如何使用同一个控制器将数据插入到不同的表中？

Question

I am using Laravel (coming from CodeIgniter) and I am struggling on getting a table that contains a foreign key populated.

I have two tables: People & Friends

My People table has fields like "First Name", "Last Name" etc.

At the bottom of my form, I can add a friend. Each friend can have a "First Name", "Last Name" etc. I can add as many friends as I like.

I am successfully populating my People table, then loop through my friends fields to populate my Friends table.

MyController.php

if ($person->save()) {  // Save the primary record.

    // check if there are any friends to save.
    $friendsArray = array_filter($input['friend']);

    if (empty($friendsArray)) {
        // No friends to insert.
    } else {
        $friend = new Friend();

        $friend->person_id = $person->id;
        $friend->friend_data = json_encode(array('friend' => $input['friend']));

        $friend->save();
    }
}

If I log out $friend, I am seeing everything correctly. For example,

[attributes:protected] => Array
    (
        [person_id] => 4
        [friend_data] => {"friend":{"firstName":"Tyler","lastName":"Durden","address":"12345 Street","city":"My City","state":"CA","zip":"12345"}}
    )

It's just not getting inserted into my Friend table. I'm not getting any errors so I'm not sure what I'm doing wrong.

EDIT

Here is what my migration looks like to create my Friends table.

...
Schema::create('friends', function (Blueprint $table) {
    $table->increments('id');
    $table->integer('person_id')->unsigned();
    $table->foreign('person_id')->references('id')->on('people');
    $table->text('friend_data');
    $table->timestamps();
});

EDIT 2

After going line by line, I am seeing this in my network tab:

Base table or view not found: 1146 Table 'myapplication.friend' doesn't exist

So that tells me I have a spelling problem somewhere. The system is looking for friend when it should be friends .

Here is what my friend model looks like:

Friend

namespace App;

use Illuminate\Database\Eloquent\Model;

class Friend extends Model
{
    //
}

Laravel uses lots of conventions. One of them is that the model's name should be the singular of the table's name. For your friends table, the model should be Friend. In case you prefer to use your own naming, you can set the table in the model like this:

protected $table = 'friends';

Your naming seems correct, I'm not sure why it isn't working.
