本文介绍了如何使用Eloquent过滤数据透视表?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述



例如:用户名::

我正在使用我正在使用的项目中的数据透视表。 find(1) - > works 给我ID为1的用户的作品。



事情是我想过滤这个

  User :: find(1) - > work-> pivot-> where('active',1) - > get(); 

其中活动是我在我的user_works数据透视表中设置的列。



这是我的User.php模型的相关部分:

 <?php 

类用户扩展Cartalyst\Sentry\Users\Eloquent\User {

public function works(){
return $ this-> belongsToMany('Work','user_works') - > withPivot('active') - > withTimestamps();
}

}

这是我的相关部分Work.php模型:

 <?php 

class工作扩展Eloquent {

public function users(){
return $ this-> belongsToMany('User','user_works') - > withPivot('active') - > withTimestamps ();
}
}

这是我的数据透视表架构:

 <?php 

使用Illuminate\Database\Migrations\Migration ;
使用Illuminate\Database\Schema\Blueprint;

class CreateUserWorksTable扩展迁移{

/ **
*运行迁移。
*
* @return void
* /
public function up()
{
Schema :: create('user_works',function(Blueprint $表){
$ table-> increment('id');

$ table-> integer('user_id') - > unsigned() - > );
$ table-> integer('work_id') - > unsigned() - > default(0);

$ table->枚举('active' array('0','1')) - > default(1);

$ table-> foreign('user_id') - > references('id') - > on('users') - > onDelete('cascade');
$ table-> foreign('work_id') - > references('id') - > on('works') - > onDelete('cascade');

$ table-> timestamps();
});
}

/ **
*反转迁移。
*
* @return void
* /
public function down()
{
Schema :: drop('user_works');
}

}

有没有办法获得数据没有为数据透视表创建新的模型?



提前感谢



编辑:
我可以这样过滤:

  return User :: find (1) - >作品() - 化合物其中( 'user_works.active', '=', '1') - >得到(); 

我不得不键入表名原始。但是,有没有更好的方式获得这个没有使用它?

解决方案

Laravel 4.1将本机 wherePivot orWherePivot 方法,这直接解决了我的问题。


I'm using a pivot table on the project I'm working with to get works of users.

E.g: User::find(1)->works gives me the works of user with ID of 1.

The thing is that I want to filter this results with extra Pivot data.

Something like:

User::find(1)->works->pivot->where('active',1)->get();

In which the active is the column I've set in my user_works pivot table.

This is my related part of my User.php model:

<?php

class User extends Cartalyst\Sentry\Users\Eloquent\User {

    public function works() {
        return $this->belongsToMany('Work','user_works')->withPivot('active')->withTimestamps();
    }

}

This is my related part of my Work.php model:

<?php

class Work extends Eloquent {

    public function users() {
        return $this->belongsToMany('User','user_works')->withPivot('active')->withTimestamps();
    }
}

This is my pivot table schema:

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;

class CreateUserWorksTable extends Migration {

    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('user_works', function(Blueprint $table) {
            $table->increments('id');

            $table->integer('user_id')->unsigned()->default(0);
            $table->integer('work_id')->unsigned()->default(0);

            $table->enum('active',array('0','1'))->default(1);

            $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
            $table->foreign('work_id')->references('id')->on('works')->onDelete('cascade');

            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop('user_works');
    }

}

Is there any way to gain the data without making a new model for the pivot table?

Thanks in advance,

Edit: I can filter this way:

return User::find(1)->works()->where('user_works.active','=','1')->get();

I had to type table name raw. But is there a better way to gain this without using it?

解决方案

Laravel 4.1 brings native wherePivot and orWherePivot methods, which is directly a solution to my problem.
