Why Am I Getting the 'Field Doesn't Have a Default Value' Error in Laravel 5.4 When Creating a Match Object?

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

Problem:

You are receiving the error "Field 'user_id' doesn't have a default value" when attempting to create a new Match object through a Deal object. Your Match class has the $guarded array set to an empty array, but this is not resolving the issue.

Solution:

The error suggests that the database table for matches requires a non-null value for the user_id column. To resolve this, update your Match class to specify the fillable fields instead of guarded fields:

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

Explanation:

In Laravel, by default, all fields are guarded, meaning that they cannot be mass-assigned. This is to prevent security vulnerabilities. By defining a fillable array, you are specifying which fields can be mass-assigned. In this case, the user_id and deal_id fields are the only ones that can be set when creating a new Match object.

By using the fillable array instead of the guarded array, you are allowing the user_id field to be set when creating a new Match. This will resolve the error and allow you to successfully create new matches.
