Laravel - Inserting multiple items using one-to-many relationship
提问by Ashley Banks
Is it possible to insert multiple values through a one-to-many relationship, so that the multiple values are saved with the foreign key.
是否可以通过一对多的关系插入多个值，这样多个值和外键一起保存。
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 justsaved project.
例如：我有一组“贡献者”，用户可以选择将其添加到项目中 - 在保存时，我希望将这些贡献者引用到刚刚保存的项目中。
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
尝试下面的代码（数组来自 $_POST['contributers'] 复选框） - 它保存数据，但不附加外键。我想避免使用循环，而只是能够批量插入所有这些
$this->project->find($project->id)
->contributers()
->insert(Input::only('contributers')['contributers']);
回答by Alexandre Butynski
You can use the createManymethod (link to source)
您可以使用该createMany方法（链接到源）
$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.
我还提出了一个小的重构：每行一个动作并使用Input::get()代替Input:only()，这是为其他用例设计的。
