Fix Laravel belongsTo Issue

I have a Laravel project where a simple belongsTo relationship is not behaving as expected. The models and migrations are already in place, yet Eloquent either returns null or throws an error whenever I attempt to pull the parent record. Here’s what I need from you: • Review the two relevant models and confirm the proper key naming and relationship declaration. • Inspect the existing migration files to verify foreign-key integrity. • Provide a concise code tweak or migration adjustment that resolves the issue, along with a brief explanation of why it works. You may work directly in PHPStorm or your preferred IDE; I’ll share the Git repository once we start. A quick video or text walkthrough outlining the fix is appreciated so I can replicate the approach on similar relationships elsewhere in the codebase.
