利用Laravel-Admin从头撸一个CRM--2

第二章 表和模型

先要确定我们都需要哪些表：

• Contacts table: 保存联系人和客户的数据
• Tasks table: 这里是任务，实际上这个任务有很多种类，包括客户需求、系统触发、条件触发等多种。
• Documents table: 文档表，这里是各种文档
• Mailbox table: 这个属于内部通信用的表

• Settings table: 系统设置，针对于CRM系统的一些设定。
  我们来看看主要的表的结构图：

  
  
  联系人
  
  

  这是联系人表。

  
  
  电话和邮件
  
  联系人电话和邮件，这里单独列出表是因为一个人可能有多个电话或者邮件。
  
  文档和状态
  
  联系人的文档和状态。
  
  任务表
  
  

  任务表、任务状态表，任务类型表，任务和文档关联表。

  
  
  文档表

文档和文档类型

设置表

系统设置表。

以上这些表是一个CRM系统中最基本的表的结构图，当然还应该有用户表，用户权限表等，幸运的是 laravel-admin 内置了非常好的权限控制，可以让我们很容易的处理用户和权限的问题。
接下来就是建立这些表

php artisan make:migration create_setting_table
php artisan make:migration create_document_type_table
php artisan make:migration create_document_table
php artisan make:migration create_task_status_table
php artisan make:migration create_task_type_table
php artisan make:migration create_contact_status_table

php artisan make:migration create_contact_table
php artisan make:migration create_contact_phone_table
php artisan make:migration create_contact_email_table
php artisan make:migration create_contact_document_table
php artisan make:migration create_task_table
php artisan make:migration create_task_document_table

接下来我们开始通过seed文件建立相应的数据表；
首先是设定表，通过上面的语句，这个文件应该已经被自动建立了，文件会在
database/migrations/XXXX_XX_XX_XXXXX_create_setting_table.php。后面

目前暂时先用这些表，当然随着功能的增加，还会增加新的表。
php artisan migrate
执行上面的命令，如果没什么错，那么恭喜你，数据库我们就算建完了。接下来的任务是往数据表里填充一些基本数据。

填充基础数据

现在我们需要用一些基础数据或者默认值填充我们的表。这个步骤也是必不可少的，因为这些数据决定了项目启动时的基本功能，首先是基本的配置文件
在 config/ directory 建立一个新的文件：seed_data.php。 修改代码：

 ['Contract', 'License Agreement', 'EULA', 'Other'],
    'task_statuses' => ['Not Started', 'Started', 'Completed', 'Cancelled'],
    'task_types' => ['Task', 'Meeting', 'Phone call'],
    'contact_status' => ['Lead', 'Opportunity', 'Customer', 'Close'],
    'settings' => ['crm_email' => '[email protected]', 'enable_email_notification' => 1],
    'permissions' => [
        'create_contact', 'edit_contact', 'delete_contact', 'list_contacts', 'view_contact', 'assign_contact',
        'create_document', 'edit_document', 'delete_document', 'list_documents', 'view_document', 'assign_document',
        'create_task', 'edit_task', 'delete_task', 'list_tasks', 'view_task', 'assign_task', 'update_task_status', 
        'edit_profile', 'compose_email', 'list_emails', 'view_email', 'toggle_important_email', 'trash_email', 'send_email',
        'reply_email', 'forward_email', 'show_email_notifications', 'show_calendar'
    ],
    'mailbox_folders' => array(
        array("title"=>"Inbox", "icon" => "fa fa-inbox"),
        array("title"=>"Sent", "icon" => "fa fa-envelope-o"),
        array("title"=>"Drafts", "icon" => "fa fa-file-text-o"),
        array("title"=>"Trash", "icon" => "fa fa-trash-o")
    )
];

然后是database/seeds/DatabaseSeeder.php 文件，修改成这样

call(UsersTableSeeder::class);

        // inserting document types
        foreach (config('seed_data.document_types') as $value) {

            DB::table('document_type')->insert([
                'name' => $value
            ]);
        }

        // insert task status
        foreach (config('seed_data.task_statuses') as $value) {

            DB::table('task_status')->insert([
                'name' => $value
            ]);
        }

        // insert task types
        foreach (config('seed_data.task_types') as $value) {

            DB::table('task_type')->insert([
                'name' => $value
            ]);
        }

        // insert contact status
        foreach (config('seed_data.contact_status') as $value) {

            DB::table('contact_status')->insert([
                'name' => $value
            ]);
        }

        // insert the system main email into settings table
        foreach (config('seed_data.settings') as $key => $value) {
            DB::table('setting')->insert([
                'setting_key' => $key,
                'setting_value' => $value
            ]);
        }
    }
}

最后执行
php artisan db:seed
然后检查一下数据是不是正常填充了。
