Project:

Create a simple php application using the laravel framework, a mysql database and the React JS framework on the frontend.

If you are familiar with that, create it as a Single Page Applications. So the backend will be pure REST API and frontend

will be compiled static javascript, which communicates with backend API only via ajax requsts.

The application will work with two DB tables, one containing users, the other containing countries.

Users will have a first name, last name, date of birth and relation to the country. Country contains only id and name.

On the home page, display a "pie chart" from the library https://echarts.apache.org/, whose parts will mean

country and the value will be the number of users in that country.

To the right of the graph, display two inputs that will serve as a date filter for the range

of dates from - to, which will be applied to the date of birth. Choose a suitable plugin for

datepicker and apply it to the inputs. After selecting the dates, this filter will be automatically

apply to the graph and will only display users whose birth dates fall within the specified range

range. This filter should be sent as a parameter to the backend where it is applied.

Below the graph, display the list of filtered users, choose the appropriate react component on

data grid in which users will be displayed. After clicking on the grid line, display a popup window,

which will display the user details in the form. Confirm the form to edit the user

on the backend and apply the change to both the table and the chart. Allow adding and deleting users.

When you are done, please test the application and check the edge cases if you are

didn't miss any usecase. Feel free to display any notifications or warnings, if you think it's needed.

Deploy the finished result to a publicly available repository.

Task: Create the necessary routes and controllers for handling CRUD operations for the user and country data (complexity: 10) (Backend) - "create the necessary routes, controllers, and models for handling CRUD operations for the user and country data."

Act as a tutor. You have to provide a step-by-step plan for solving only for this task. You have to provide high-level code templates only for this task with placeholders for actual implementation by students.

List required classes.

AI:

Step-by-step plan:

  1. Create a new Laravel project by running the command "composer create-project --prefer-dist laravel/laravel projectname" in your terminal.

  2. Create a new model for the "users" table by running the command "php artisan make:model User" in your terminal. This model should contain the necessary fields for the "users" table, such as first name, last name, date of birth, and relation to the country.

  3. Create a new model for the "countries" table by running the command "php artisan make:model Country". This model should contain the necessary fields for the "countries" table, such as id and name.

  4. Create a new controller for handling CRUD operations for the "users" table by running the command "php artisan make:controller UserController" in your terminal.

  5. Create a new controller for handling CRUD operations for the "countries" table by running the command "php artisan make:controller CountryController" in your terminal.

  6. In the UserController, create new methods for handling the following CRUD operations:

  • index(): to display a list of all users

  • create(): to display a form for creating a new user

  • store(): to handle the form submission and create a new user in the database

  • show(): to display the details of a specific user

  • edit(): to display a form for editing a specific user

  • update(): to handle the form submission and update the user in the database

  • destroy(): to delete a specific user from the database

  1. In the CountryController, create new methods for handling the following CRUD operations:

  • index(): to display a list of all countries

  • create(): to display a form for creating a new country

  • store(): to handle the form submission and create a new country in the database

  • show(): to display the details of a specific country

  • edit(): to display a form for editing a specific country

  • update(): to handle the form submission and update the country in the database

  • destroy(): to delete a specific country from the database

  1. Create new routes in the "web.php" file that map to the appropriate methods in the UserController and CountryController. For example:

Route::get('/users', 'UserController@index');

Route::get('/users/create', 'UserController@create');

Route::post('/users', 'UserController@store');

Route::get('/users/{id}', 'UserController@show');

Route::get('/users/{id}/edit', 'UserController@edit');

Route::patch('/users/{id}', 'UserController@update');

Route::delete('/users/{id}', 'UserController@destroy');

  1. Create new routes in the "web.php" file that map to the appropriate methods in the CountryController.

  2. Test all routes and controllers using Postman or a similar tool to ensure that CRUD operations are working as expected.

Classes required:

  • User model

  • Country model

  • UserController

  • CountryController

  • web.php (routes)

  • show(): to display the details of a specific country

  • update(): to handle the form submission and update the country in the database

  • destroy(): to delete a specific country from the database

  1. In the "api.php" file, create new routes that map to the appropriate methods in the UserController and CountryController. For example:

Route::get('/users', 'UserController@index');

Route::post('/users', 'UserController@store');

Route::get('/users/{id}', 'UserController@show');

Route::patch('/users/{id}', 'UserController@update');

Route::delete('/users/{id}', 'UserController@destroy');

  1. In the "api.php" file, create new routes that map to the appropriate methods in the CountryController.

  2. Test all routes and controllers using Postman or a similar tool to ensure that CRUD operations are working as expected.

Classes required:

  • User model

  • Country model

  • UserController

  • CountryController

  • api.php (routes)

Note: You may also need to create a migration file to create the appropriate tables in the database and also run the migration command to create the tables.

UserController describe

AI:

The UserController is a class that handles CRUD (Create, Read, Update, and Delete) operations for the "users" table in the database. It contains several methods, each responsible for a specific action related to the users.

Here is a brief description of each method:

  1. index(): This method is responsible for fetching all the records from the "users" table and returning them to the client. It can be accessed using a GET request to the /users route.

  2. store(): This method is responsible for handling the form submission and creating a new user in the database. It can be accessed using a POST request to the /users route.

  3. show(): This method is responsible for fetching a specific user from the "users" table and returning it to the client. It can be accessed using a GET request to the /users/{id} route, where {id} is the id of the user you want to retrieve.

  4. update(): This method is responsible for handling the form submission and updating a user in the database. It can be accessed using a PATCH request to the /users/{id} route, where {id} is the id of the user you want to update.

  5. destroy(): This method is responsible for deleting a specific user from the "users" table. It can be accessed using a DELETE request to the /users/{id} route, where {id} is the id of the user you want to delete.

Note: The methods in UserController and their corresponding routes may vary depending on your implementation, but the basic functionality of each method will remain the same.

Here is a list of the required endpoints for handling CRUD operations for the user data:

  1. GET /users - This endpoint is used to retrieve a list of all users from the database.

  2. POST /users - This endpoint is used to create a new user in the database. The client should send the necessary information for the new user in the request body.

  3. GET /users/{id} - This endpoint is used to retrieve a specific user from the database. The {id} path parameter should be replaced with the id of the user you want to retrieve.

  4. PATCH /users/{id} - This endpoint is used to update a specific user in the database. The {id} path parameter should be replaced with the id of the user you want to update and the client should send the updated information in the request body.

  5. DELETE /users/{id} - This endpoint is used to delete a specific user from the database. The {id} path parameter should be replaced with the id of the user you want to delete.

Note: These endpoints are just examples and their naming or methods may vary depending on your implementation.

AI:

You are correct that a filter can work without specific fields, but in this case, it would be more efficient and user-friendly to have specific fields for the country and birthdate range in the form submission. This way, the user can easily understand what information is required to filter the users, and the backend can process the filter more efficiently.

It is also important to note that without specific fields for the filter, you will have to rely on some kind of parsing or string manipulation to extract the filter criteria from the request body, which may be more complex and error-prone.

In summary, while it is possible to filter the users without specific fields for the country and birthdate range in the form submission, it is recommended to include them for better user experience and easier implementation.

Here are some example methods and their brief descriptions for testing the user endpoints along with some caveats/setup required for each test:

  1. testRetrieveAllUsers(): This test should send a GET request to the /users endpoint and check if the response contains a list of all users in the database. This test should be run after setting up some test data in the users table.

  2. testCreateUser(): This test should send a POST request to the /users endpoint with the necessary information for a new user and check if the response contains the newly created user and if the user is added to the database. This test should be run after clearing the users table and setting up any necessary test data for the country table.

  3. testRetrieveUser(): This test should send a GET request to the /users/{id} endpoint with a valid user id and check if the response contains the correct user. This test should be run after setting up some test data in the users table.

  4. testUpdateUser(): This test should send a PATCH request to the /users/{id} endpoint with a valid user id and updated information and check if the response contains the updated user and if the user is updated in the database. This test should be run after setting up some test data in the users table.

  5. testDeleteUser(): This test should send a DELETE request to the /users/{id} endpoint with a valid user id and check if the response is successful and if the user is deleted from the database. This test should be run after setting up some test data in the users table.

  6. testFilterUsers(): This test should send a GET request to the /users/filter?country=&from=&to= endpoint with valid parameters for country and birthdate range and check if the response contains the filtered users. This test should be run after setting up some test data in the users and countries table.

  7. testInvalidFilterParameters(): This test should send a GET request to the /users/filter?country=&from=&to= endpoint with invalid or missing parameters and check if the response contains the appropriate error message or status code.

  8. testInvalidUpdateDeleteParameters(): This test should send a PATCH or DELETE request to the /users/{id} endpoint with invalid or missing parameters and check if the response contains the appropriate error message or status code.

  9. testInvalidCreateParameters(): This test should send a POST request to the /users endpoint with invalid or missing parameters and check if the response contains the appropriate error message or status code.

  10. testUnauthorizedAccess(): This test should send a request to the user endpoints without proper authentication and check if the response contains the appropriate error message or status code.

Please note that the above tests are just examples and the implementation may vary depending on your project.

larvel middleware catch error return json

AI:

In Laravel, you can create a custom middleware to handle errors and return a JSON response instead of a view. Here are the steps to create such a middleware:

  1. Create a new middleware class using the command php artisan make:middleware JsonErrorMiddleware. This command will create a new file JsonErrorMiddleware.php in the app/Http/Middleware directory.

  2. In the handle method of the middleware class, you can catch any exception that is thrown in the application. For example:


    public function handle($request, Closure $next)

    {

        try {

            return $next($request);

        } catch (\Exception $e) {

            return response()->json(['error' => $e->getMessage()], $e->getStatusCode());

        }

    }
  1. In the Kernel.php file, you can register the middleware as a global middleware so that it will be run on every request. For example:

    protected $middleware = [

        // ...

        \App\Http\Middleware\JsonErrorMiddleware::class,

    ];
  1. You can also specify the middleware for a specific route group or routes.

Note that this middleware catches all exception and return them in json format, it is recommended to use it in development environment only, in production environment it's better to use a more sophisticated way of error handling such as logging the error and notifying the developer team.
