Laravel-使用一对多关系插入多个项目

Question

Is it possible to insert multiple values through a one-to-many relationship, so that the multiple values are saved with the foreign key.

So for example: I have an array of 'contributers' which a user can select to add to a project - upon saving I want these contributers to be referenced to the just saved project.

Trying the code below (the array is coming from $_POST['contributers'] which are checkboxes) - it saves the data, but doesn't attach the foreign key. I want to avoid having to use a loop and just be able to bulk insert all of these

$this->project->find($project->id)
      ->contributers()
       ->insert(Input::only('contributers')['contributers']);

Answer 1

You can use the createMany method ( link to source )

$project = $this->project->find($project->id);
$project->contributers()->createMany(Input::get('contributers'));

I also propose a small refactoring : one action per line and use of Input::get() instead of Input:only() , which is designed for other use cases.
