hello
Hello! How can I assist you today?
consider the below problem statement and design database schema for it considering that multiple users can submit the same form and also write the attributes associated with each of collection created for the solution : The lifecycle of data collection via this platform does not end with the submission of a response. There is usually some post-submission business logic that the platform needs to support over time. Some real-life examples -
To address the requirements outlined in the problem statement, we can create a relational database schema that includes the following tables and their associated attributes:
Forms
Questions
Responses
Answers
For the Google Sheets use case, we can implement a solution where each response to the form becomes a row in the Google Sheet, and questions in the form become columns. This can be achieved through a separate process that populates the Google Sheets using the data from the Responses and Answers tables. The metadata associated with the Google integration can include details such as the Google Sheets API credentials, sheet format, and update frequency.
To demonstrate a plug-and-play fashion for handling post-submission business logic, we can consider the example of sending an SMS to the customer as soon as the ingestion is complete. This can be achieved by introducing a new table, "ScheduledActions", with attributes including action_id, response_id, action_type, action_status, and scheduled_time. This table can be used to schedule and manage various post-submission actions, allowing for seamless integration of new use cases in the future.
By designing the schema in this manner, we can provide a flexible and extensible data model that supports various post-submission business logic requirements and enables seamless integrations with external systems.
write other attribute for above collections which are marked as other attributes
Certainly! Here are additional attributes for the collections mentioned previously:
These additional attributes provide more granular details and flexibility to the database schema, enabling a comprehensive and extensible solution for handling various post-submission business logic and integration requirements.
write the datatype for designing the schema in mongodb ?
When designing the schema in MongoDB, we can define the datatype for each attribute as follows:
In MongoDB, we use specific datatypes such as ObjectId for unique identifiers, String for textual data, Date for date and time values, Boolean for true/false values, Number for numeric data, and Array/Object for complex data structures. These datatypes allow for flexibility and scalability in the schema design within a MongoDB environment.
write nodejs route handler for above problem statement ?
Creating route handlers in Node.js typically involves using a web framework like Express.js. Here is an example of how you might create Express route handlers for the previously described database schema. Note this is simplified code and might need to be adjusted to meet additional criteria. Error handling and security measures, such as data validation and sanitization, are not included in this example to focus on the main structure.
const express = require('express'); const router = express.Router(); // Mongoose models const Form = require('./models/Form'); const Question = require('./models/Question'); const Response = require('./models/Response'); const Answer = require('./models/Answer'); const ScheduledAction = require('./models/ScheduledAction'); // Create Route Handlers... // Get All Forms router.get('/forms', async (req, res) => { const forms = await Form.find(); res.json(forms); }); // Get a Specific Form router.get('/forms/:id', async (req, res) => { const form = await Form.findById(req.params.id); res.json(form); }); // Add a New Form router.post('/forms', async (req, res) => { const newForm = new Form(req.body); const savedForm = await newForm.save(); res.json(savedForm); }); // Update a Form router.put('/forms/:id', async (req, res) => { const updatedForm = await Form.findByIdAndUpdate(req.params.id, req.body); res.json(updatedForm); }); // Delete a Form router.delete('/forms/:id', async (req,) => { const deletedForm = await.findByIdAndRemove(req.params.id); res.json(deletedForm); }); // Similar route handlers can be created for Questions, Responses, Answers, and ScheduleActions module.exports = router;
These are some basic CRUD (Create, Read, Update, Delete) operations. The actual functionality, like connecting to the database and defining what to do with the received data, depends on how you structure your Node.js application.
consider the problem statement that i had given you at the start and for that write node js route handler for storing form data in their corresponding collections ?
In Express.js, a route handler for storing form data in the corresponding MongoDB collections might look like this:
Please install necessary npm packages like express, mongoose, and body-parser.
const express = require('express'); const router = express.Router(); const mongoose = require('mongoose'); const Form = require('./models/Form'); const Question = require('./models/Question'); const Response = require('./models/Response'); const Answer = require('./models/Answer'); router.post('/submit-form', async (req, res) => { // Assuming the request body has the structure formData = { form, questions, responses, answers } const session = await mongoose.startSession(); session.startTransaction(); try { const form = new Form(req.body.form); await form.save({ session: session }); const questions = req.body.questions.map(question => { question.form_id = form._id; return new Question(question); }); await Question.insertMany(questions, { session: session }); const response = new Response({ ...req.body.response, form_id: form._id }); await response.save({ session: session }); const answers = req.body.answers.map(answer => { answer.response_id = response._id; return new Answer(answer); }); await Answer.insertMany(answers, { session: session }); await session.commitTransaction(); res.status(200).send({ msg: 'Form data submitted successfully' }); } catch (error) { await session.abortTransaction(); res.status(500).send({ error: 'An error occurred when saving form data' }); } finally { session.endSession(); } }); module.exports = router;
This route handler creates a new in the "Forms", "Questions", "Responses", and "Answers" collections based on incoming form data. For robustness, the operations are performed in a transaction (provided by MongoDB 4.0 and later) to ensure that if an error occurs during any step in the process, none of the steps are applied. This keeps your data consistent and avoids situations, for example, a Form exists without any associated Questions, Answers, or Responses. The structure and fields of the incoming form data are assumed, you should modify it accordingly.
You could then call this route handler via a client-side action such as a form submission event.
write separate route handler for each requests like '/submit-form/:id' : that adds responses of user into database, '/get-form/ : that sends the form to client, '/create-form/' : creates form by accepting request and based on that stores data into forms, questions, answers collection
Sure, I will break down the operations into separate route handlers along with appropriate HTTP verbs. We'll need Express.js and Mongoose package in Node.js to do this.
const express = require('express'); const mongoose = require('mongoose'); const router = express.Router(); const Form = require('./models/Form'); const Question = require('./models/Question'); const Response = require('./models/Response'); const Answer = require('./models/Answer'); // Route Handler to Create a Form routercreate-form', async (req, res) => { const session = await mongoose.startSession(); session.startTransaction(); try { const form = new Form(req.body.form); await form.save({ session: session }); const questions = req.body.questions.map((question) => { question.form_id = form._id; return new Question(question); }); await Question.insertMany(questions, { session: session }); await session.commitTransaction(); res.status(200).send({ msg: 'Form created successfully' }); } catch (error) { await session.abortTransaction(); res.status(500).send({ error: 'An error occurred when creating the form.' }); } finally { session.endSession(); } }); // Route Handler to Get a Form router.get('/get-form/:id', async (req, res) => { try { const form = await Form.findById(req.params.id); const questions = await Question.find({ form_id: req.params.id }); res.status(200).send({ form, questions }); } catch (error) { res.status(500).send({ error: 'An error occurred when fetching the form.' }); } }); // Route Handler to Submit a Form router.post('/submit-form/:id', async (req, res) => { const session = await mongoose.startSession(); session.startTransaction(); try { const response = new Response({ ...req.body.response, form_id: req.params.id }); await response.save({ session: session }); const answers = req.body.answers.map((answer) => { answer.response_id = response._id; return new Answer(answer); }); await Answer.insertMany(answers, { session: session }); await session.commitTransaction(); res.status(200).send({ msg: 'Form submitted successfully' }); } catch (error) { await session.abortTransaction(); res.status(500).send({ error: 'An error occurred when submitting the form.' }); } finally { session.endSession(); } }); module.exports = router;
For these route handlers:
for the /submit-form/:id request I am storing the response in response collection but in response collection I need to store the formid that i will get from req.params.id but how do i store the question id then ?
To store the response along with the associated question IDs, we can modify the route handler for the '/submit-form/:id' request.
When a user submits a response to a form, the request body should contain the response data, including the IDs of the questions being answered. We can then use this information to store the response and associated question IDs in the Response collection as follows:
// Route Handler to Submit a Form router.post('/submit-form/:id', async (req, res) => { const formId = req.params.id; const responseData = req.body.response; const answerData = req.body.answers; try { const response = new Response({ form_id: formId, // Save other response data }); const savedResponse = await response.save(); const answerDocs = answerData.map(answer => { return new Answer({ response_id: savedResponse._id, question_id: answer.question_id, // Assuming the answer object contains the question_id answer_text: answer.answer_text // Assuming the structure of answer object // Save other answer data }); }); await Answer.insertMany(answerDocs); res.status(200).json({ message: 'Form submitted successfully' }); } catch (error) { res.status(500).json({ error: 'An error occurred when submitting the form.' }); } });
In this code, we assume that the answer objects in the request body contain the question_id field to link each answer to its corresponding question. We use this information to associate each answer with its respective question in the Answer collection.
Please replace the placeholder comments with the actual code to save the response and answer data based on your document structure and schema design.
how would the incoming form will have questions id ?
The incoming form will typically have questions associated with it, and these questions will have unique identifiers (IDs) that can used to link them to responses.
Assuming that you have a form creation process where you define the questions for the form, you can assign unique IDs to each question as part of the form creation process. For example, when you create a form and its associated questions, you can assign an ID to each question before saving it to the database.
When a user submits a form response, the request should include the form ID and the answers to the questions, where each answer includes the question ID it pertains to. This information allows you to link each to the corresponding question.
For example, in a form creation interface, you might have a way to add questions to the form. Each question added to the form will have an associated question ID. When the form is submitted, the front-end or client application needs to send the form ID along with the question IDs and answers for each question.
In the backend, you can then use this information to associate the responses with the corresponding questions by matching the question IDs from the request body to the question IDs in the database.
It's essential to ensure that the client application sends the question IDs along with the answers when submitting the form. This allows you to accurately link each answer to its respective question when storing the response and answer data in the database
that means when we service the get-form request we will send form that will form id and questions with their ids as well so that when user submits the form we will have questions id as well ?
Exactly, that's correct. When servicing the get-form
request, you should send the form details along with the questions and their IDs. This allows the client to have access to the question IDs when presenting the form to the user.
By providing the questions with their IDs, you ensure that when the user submits the form, the request includes the necessary question IDs along with the answers. This way, you can accurately link each answer to its corresponding question when processing the form submission on the server side.
When sending the form details to the client in response to the get-form
request, make sure to include the question IDs as part of the questions' data. This will allow the client to handle form submissions effectively and provide the server with the required information to properly store the response and associated question IDs.
Ensuring that the client has access to the question IDs is crucial for maintaining data integrity and accurately linking responses to their corresponding questions in the database.
how will i then create a form that will have form id as well questions with their id also ?
When creating a form with questions and their respective IDs, you can follow a structured approach where each question is associated with a unique identifier (ID) within the form. Here a general guideline on how you can handle this process:
Form Creation in the Backend:
Adding Questions to the Form:
Sending Form with Questions and IDs to Client:
get-form
request, the server would send the form details to the client. This form object should include the form ID and an array of questions, with each question containing its unique identifier (ID).Client-Side Representation:
Submitting Form with Question IDs:
Server-Side Processing:
By following this approach, you can ensure that the form creation, representation in the client application, and form submission all maintain the necessary linkage between questions and their unique identifiers, facilitating accurate data storage and retrieval.
write code for it ?
Certainly! Below is an example of how you might create a form with questions and their IDs in a Node.js application using Express.js. This example assumes the use of an in-memory store for simplicity, but in a real application, you would likely use a database to store and retrieve form and question data.
const express = require('express'); const app = express(); app.use(express.json()); // In a real application, you would have a database to store form and question data. // For simplicity, we'll use in-memory arrays to store the data. let forms = []; // Route to create a form with questions app.post('/forms', (req, res) => { const { title, description, questions } = req.body; // Generate a unique form ID (you can use a library like uuid for this) const formId = forms.length + 1; const newForm = { id: formId, title, description, questions: questions.map((question, index) => { return { id index + 1, // Assign a unique ID to each question text: question }; }) }; forms.push(newForm); res.json(newForm); }); // Route to get a specific form by ID app.get('/forms/:id', (req, res) => { const formId = parseInt(req.params.id); const form = forms.find(form => form.id === formId); if (form) { res.json(form); } else { res.status(404).json({ message: 'Form not found' }); } }); // Route to submit form with question IDs app.post('/submit/:id', (req, res) => { const formId = parseInt(req.params.id); const form = forms.find(form => form.id === formId); if (!form) { res.status(404).json({ message: 'Form not found' }); return; } // Assuming the request body includes the answers with question IDs const { answers } = req.body; // Here you can process and store the form submission data, linking answers to their respective questions res.json({ message: 'Form submitted successfully' }); }); app.listen(3000, () => { console.log('Server is running on port 3000'); });
In this example, the /forms
route allows the creation of a new form with questions, each with its unique ID. The /forms/:id
route provides a way to retrieve a specific form, including the questions with their IDs. The /submit-form/:id
route demonstrates how you might handle a form submission, including processing the answers with their respective question IDs.
i am making the application assuming, first the form is created by serving the request create-form where a form is stored in form collection with a form-name, and questions are stored in questions collection and during stroing mongodb will automatically creates id for these questions, and also we are storing the answers of questions in answers collection. So, now if we get a get-form/:id request from client we will fetch the form id and based on that corresponding questions from questions collection and send the form to client and now when client sends the form to route handler submit-form/:id then handler will take form id and stores user response in response collection but here i am getting an issue that i want to store for each response their corresponding question id also ?
I understand your scenario. To address the issue storing each response with its corresponding question ID, you can modify the code to include the question IDs when a user submits a response to a form.
Here's how might approach this:
Fetching Form and Questions from the Database:
When handling the get-form/:id
request, you retrieve the form details from the form collection. Along with the form details, you fetch the corresponding questions from the questions collection for that form ID.
Submitting Form Response Question IDs:
When a user submits a response to the form via the submit-form/:id
route, the request body should contain the response data and the question IDs associated with each answer.
Storing Response with Question IDs:
In the route handler for submit-form/:id
, after storing the response, you also store the question IDs along with the user's answers in the response collection.
Here's an example of how you can achieve this using Mongoose, a popular ODM for MongoDB, in a Node.js application:
const express = require('express'); const app =const mongoose = require('mongoose'); // Assuming you've the schemas for form, question, and response const Form = require('./models/form'); const Question = require('./models/question'); const Response require('./models/response'); app(express.json()); // Set up MongoDB connection mongoose.connect('mongodb://localhost:27017/your-database-name', { useNewUrlParser: true, useUnifiedTopology: true }) .then(() => console.log('Connected to MongoDB')) .catch(err => console.error('Could not connect to MongoDB', err)); // Route to get form and questions by form ID app.get('/get-form/:id', async (req, res) => { const formId = req.params.id; try { const form = await Form.findById(formId); const questions = await Question.find({ form_id: formId }); res.json({ form, questions }); } catch (error) { res.status(500).json({ error: 'An error occurred when fetching the form and questions' }); } }); // Route to submit form response app.post('/submit-form/:id', async (req, res) => { const formId = req.params.id; const responseData = req.body.response; const questionIds = req.body.questionIds; // Assuming the client sends question IDs along with the response try { const response = new Response({ form_id: formId, // Save other response data }); const savedResponse = await response.save(); // Store responses with question IDs const responseDetails = questionIds.map((questionId, index) => { return { response_id: savedResponse._, question_id: questionId, answer_text: responseData[index] // Assuming the answers match the order of question IDs }; }); await ResponseDetail.insertMany(responseDetails); res.status(200).json({ message: 'Form submitted successfully' }); } catch (error) { res.status(500).json({ error: 'An error occurred when submitting the form' }); } }); app.listen(3000, () => { console.log('Server is running on port 3000'); });
In this example, we assume that you've defined the Mongoose schemas for Form
, Question
, Response
. When a form is fetched, both the form and its associated questions are sent to the client. When the form is submitted, the response is stored along the question IDs in the ResponseDetail
collection.
how the stricture of response should : will it be like their is a separate document each having clientId, formId, responseID, response, questionID or any other way of storing because if we have 10 questions and 10 users then for above appeoach each user will have 10 documents in response collection and then a total of 100 documents for all users ?
When designing the structure for storing form responses, especially in a scenario with a large number of forms and users, it's essential to consider the trade-off between query performance and database size. Here are a few approaches you can consider:
const UserSchema = new mongoose.Schema({ clientId: String, // Other user details responses: [{ formId: String, responseId: String, answers: [{ questionId: String, answer: String }] }] });
const ResponseSchema = new mongoose.Schema({ clientId: String, formId: String, responseId: String, answers: [{ questionId: String, answer: String }] });
const FormResponseSchema = new mongoose.Schema({ formId: String, // Other form details responses: [{ clientId: String, responseId: String, answers: [{ questionId: String, answer: String }] }] });
It's important to consider your specific use cases when designing the structure for form responses. If your application frequently needs to access individual responses, keeping each response in a separate document might be appropriate. On the other hand, if you often need to analyze or aggregate responses, a structure that allows for that aggregation might be more suitable.
Consider indexing the fields that are frequently queried for better performance and always keep an eye on the potential impact of the chosen structure on database size and query complexity.
