I wrote an article on how to resolve the error "local.ERROR Creating default object from empty value" in Laravel.

What kind of error occurs

local.ERROR: Creating default object from empty value {“exception”:“[object] (ErrorException(code: 0): Creating default object from empty value at /app/Http/Controllers/PostController.php:30)

This is the kind of error you will encounter.

Why does the error occur?

The fundamental cause of this error is that:

The database column is required but contains no data

This is the reason for the error.

In other words,

1. In the database design, consider not making it mandatory in the first place
2. In the database design, set a default value (initial value when no input is given)
3. Check if the expected data is not being received

I think you should take appropriate action from these 3 points.

① How to make the database design not mandatory in the first place

By adding nullable() to the migration file, it is possible to allow null.

Modify the migration file

  Schema::create('items', function (Blueprint $table) {
      $table->id();
      $table->string('title')->nullable(); // Add nullable()
      $table->timestamps();
  });

This can be set for each column.

② How to set a default value in the database design

By adding default value in the migration file, you can insert the value set as default when no data is entered.

Modify the migration file

Schema::create('items', function (Blueprint $table) {
    $table->id();
    $table->string('title')->default('No Title'); // Add default()
    $table->timestamps();
});

In this way, if no data is entered, "No Title" will be inserted into the column.

③ Check if the expected data is not being received

For example, in the controller:

$item = new Item;
$item->title = $request->title;
$item->save();

If you encounter the error message at the beginning, it may be because:

$request->title

May not have any data.

You can deal with this by checking the content using:

dd($request->title);

If this is null, consider how data can be entered into $request->title.

Summary

That's all for now.

I hope this can be helpful to someone.
