Easy Crud using Laravel

Easy Crud using Laravel

Creating, reading, updating, and deleting resources is used in pretty much every application. Laravel helps make the process easy using resource controllers. Resource Controllers can make life much easier and takes advantage of some cool Laravel routing techniques. Today, we’ll go through the steps necessary to get a fully functioning CRUD.

We will use CRUD generator for Laravel 5.x for crud functions.

 

Installation:

  1. Download:
    • Run composer require nvd/crud-generator from the project directory
  2. Register the Service Provider in config/app.php:
    'providers' => [
        ...
        ...
        Nvd\Crud\Providers\NvdCrudServiceProvider::class,
    ],
    
  3. Publish configuration file and view templates:
    • Run php artisan vendor:publish from the project directory
  4. Done!

Usage:

Run php artisan nvd:crud table_name

Now you can access http://your-site.com/table-name to access the CRUD app. (Here table-name refers to the singular, slugged version of the table name. e.g.

Customizing NVD CRUD Generator:

Configuration File

NVD CRUD generator publishes a configuration file config/crud.php. You can modify the default settings of the package here. The file is completely documented and hence self explanatory.

Templates

In case you don’t like the default code that is generated for you, the templates for the generated model, controller and the views are located in the /resources/views/vendor/crud directory. You are free to edit them as you like. Or make a copy of any of the templates directory and refer to it in the config/crud.php.

 

Known Problems and Their Solution:

Layout and Styling

  • The default view templates use vendor.crud.common.app template as the layout. If you are using a different layout, specify it in the config/crud.php
  • The default view templates use classes from Bootstrap and Font Awesome. You can edit the templates and not use them or you can simply include them in your layout like the one below:
<!DOCTYPE html>
<html>
<head>
    <title>Laravel Sandbox</title>
    <link rel="stylesheet" href="path/to/bootstrap.min.css">
    <link rel="stylesheet" href="path/to/font-awesome.min.css">
</head>
<body>




<div class="container">




<div class="content">
        @yield("content")
    </div>




</div>




</body>
</html>

Routes Declaration:

  • For Laravel 5.2, the generator generates routes inside the closure of the route group that applies the ‘web’ middleware group in the /app/Http/route.php out of the box, as follows:
    Route::group(['middleware' => ['web']], function () {
        Route::resource('user-profile','UserProfileController');
        //
    });
    

    If, for some reasons, the routes are generated outside the closure, you should move them inside to avoid any exception while creating, editing or deleting a resource.

  • You can also tell the generator explicitly where to declare the routes by adding a comment: ‘nvd-crud routes go here’ and the generator will place the route declaration just after the comment.
    Route::group(['middleware' => ['web']], function () {
        // nvd-crud routes go here
    });
    

Exception: Class “Input” not found

  • Although it happens rarely, sometimes the facade “Input” is not declared in config/app.php. Declare the alias and the exception will be gone:
    'aliases' => [
        //
        'Input'     => Illuminate\Support\Facades\Input::class,
        //
    ],

Note: Use of Input facade was removed in the latest version. So this error is expected not to appear anyway.

Primary Keys Other Than ‘id’

  • At the moment NVD CRUD generator accepts only ‘id’ column as the primary key. Having a primary key other than ‘id’ will be supported in upcoming versions. But right now, you have to follow the convention.

Laravel Eloquent Conventions

  • For smooth operations, Laravel conventions should be followed when creating database tables. If you are facing errors / exceptions mentioning primary keys, table names or timestamps (created_at, updated_at), please refer to Laravel docs about conventions.
