How to Fix the 'Field Doesn't Have a Default Value' Error in Laravel 5.4?

Resolving "Field Doesn't Have a Default Value" Error in Laravel 5.4

When attempting to create a new Match entity using the Deal model, you may encounter the error "Field 'user_id' doesn't have a default value." This occurs despite having defined an empty guarded array in the Match class.

To resolve this issue, you should replace the guarded array with the fillable array:

protected $guarded = [];
protected $fillable = ['user_id', 'deal_id'];

By specifying the fillable array, you explicitly define the fields that can be mass assigned to the model. This ensures that only authorized fields are updated when creating or updating the Match entity.

The fillable array should include all the fields that you want to be able to set when creating or updating the model using the mass assignment syntax. In this case, you want to be able to set both the user_id and deal_id when creating a new Match.

Once you have made this change, you should be able to create new Match entities without receiving the "Field Doesn't Have a Default Value" error.
