Admin background is an integral part of modern web application development. It provides developers with a convenient interface for managing and monitoring application data. Dcat Admin is a powerful management background framework, which is developed based on the Laravel framework and provides rich functions and flexible scalability. This article will give you an in-depth understanding of Dcat Admin and provide you with an application guide for getting started.
Part 1: Introducing Dcat Admin
1.1 Overview of Dcat Admin
Dcat Admin is an open source management background framework, which aims at rapid development and flexibility. It is built on the Laravel framework and written in PHP language. Dcat Admin provides a rich set of page components, form building tools, data display and operation functions, allowing developers to easily build a beautiful and easy-to-use management background.
1.2 Features of Dcat Admin
Dcat Admin has many impressive features, here are some of the highlights:
Rapid development: Dcat Admin provides a wealth of predefined components and templates, enabling developers to quickly build a fully functional management background.
Scalability: Dcat Admin supports adding new functions and components through plug-ins and extensions to meet the needs of different projects.
Data visualization: Dcat Admin provides various data visualization components, such as charts, maps, etc., to facilitate developers to analyze and display data.
Multilingual support: Dcat Admin supports multiple languages, and developers can easily implement an internationalized management background.
Responsive layout: Dcat Admin's page components are carefully designed to adapt to different screen sizes and device types.
Part II: Install and configure Dcat Admin
2.1 Environmental requirements
Before starting to use Dcat Admin, you need to ensure that the following environment requirements are met:
PHP >= 7.2
Laravel >= 5.7
Composer
2.2 Install Dcat Admin
Installing Dcat Admin is very simple, just execute a few commands:
bash
Copy
# Use Composer to install Dcat Admin
composer require jqhph/dcat-admin
# Publish resource files
php artisan vendor:publish --provider="Dcat\Admin\AdminServiceProvider"
2.3 Configure Dcat Admin
After the installation is complete, you need to do some basic configuration to ensure that Dcat Admin can work properly.
First, open the config/admin.php file and configure the database connection information:
php
Copy
'database' => [
// database connection name, the default is `mysql`
'connection' => 'mysql',
// Database table prefix, default is empty
'prefix' => '',
// Specify the database connection configuration, the default is `default`
'connection_name' => 'default',
],
Next, you also need to create a data table for managing the background. Execute the following commands on the command line:
bash
Copy
php artisan admin:install
This will create the required tables and generate an initial admin account and password. You can use this account to log in to the management background.
Part 3: Building the management background
3.1 Create a background controller
In Laravel, controllers are responsible for handling requests and responses. To use Dcat Admin, you need to create a controller that inherits from Dcat\Admin\Controllers\AdminController. For example, create a controller named UserController:
php
Copy
<?php
namespace App\Admin\Controllers;
use Dcat\Admin\Controllers\AdminController;
class UserController extends AdminController
{ // ... } 3.2 Define resource routing
Next, define resource routes in the routes/web.php file to map requests to corresponding controller methods:
php
Copy
<?php
use App\Admin\Controllers\UserController;
Route::resource('users', UserController::class);
This will generate regular CRUD routes, including routes for displaying, creating, editing, and deleting users.
3.3 Create model and database migration
Before managing data with Dcat Admin, you need to create corresponding models and database migrations. Assuming you want to manage user data, first create a User model:
bash
Copy
php artisan make:model User
Then, generate the database migration file:
bash
Copy
php artisan make:migration create_users_table --create=users
In the generated migration file, define the fields and indexes of the user table:
php
Copy
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateUsersTable extends Migration
{
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
}
public function down()
{ Schema::dropIfExists('users'); } } Run the migration command to create the user table:
bash
Copy
php artisan migrate
3.4 Register resources to the management background
The last step is to register the user resource with the management background. Open the app/Admin/routes.php file and add the following code:
php
Copy
<?php
use App\Admin\Controllers\UserController;
use Dcat\Admin\Admin;
Admin::resource('users', UserController::class);
Now, you can access the /admin/users path to view and manage user data.
Part Four: Extensions and Customizations
4.1 Using plugins
Dcat Admin supports extending functions through plug-ins. You can find various useful plug-ins in the Dcat Admin plug-in market, such as file management, rights management, etc. After downloading the plugin, install it into your project and configure and use it according to the plugin documentation.
4.2 Custom pages and styles
Dcat Admin provides a rich set of page components and styles, but you may wish to customize it to meet your project needs. You can edit the view files in the resources/views/admin directory to customize the page layout and style.
4.3 Custom forms and lists
Dcat Admin provides powerful form building tools and data list functions. You can customize form fields, validation rules, and list display methods according to your specific needs. Check out the Dcat Admin documentation to learn more about how to customize forms and lists.
