Laravel多对多在现有的Pivot上进行旋转

Question

I have a situation in Laravel 5.1 where I would like to add a many-to-many relationship to an existing relationship. According to the diagram below, I already have all the items in green working.

The issue is that since there isn't a primary key on the issue_person table, I don't know how to add a many-to-many relationship to Users. Does anyone know how I would go about accomplishing this?

Answer 1

So it appears that a simple answer to this is to write a migration that adds a primary key to the original issue_person pivot table, and then set up a many-to-many relationship between issue_person and user using the position_user table.

My migration looks like this:

public function up()
{
    Schema::table('issue_person', function (Blueprint $table) {
        $table->increments('id');
    });
}

public function down()
{
    Schema::table('issue_person', function (Blueprint $table) {
        $table->dropColumn('id');
    });
}
