Laravel Get Data From Relation Table

I'm building a project with Laravel 7.28. I have three tables named; projects, tags and project_tags. in project_tags table there is project_ids and tag_ids. It looks like this:

database_schema

I need to get all projects with their tag and secondly I need to get projects with certain tag. So What should I do in models? Which function and how should I use? And how can I get data?

I discovered rtconner/laravel-tagging package but is it the correct way to do it? Thanks for your help

You might want to create a many to many relationship between projects and tags.

class Project extends Model
{
    public function tags()
    {
        return $this->belongsToMany(Tag::class, 'project_tags')->withTimestamps();
    }
}

Then:

// Get all projects with their tags.
Project::with('tags')->get();

// Get projects contain certain a certain tag.
Project::whereHas('tags', function ($query) {
    return $query->where('tag', 'some value');
})

In addition, tags tend to be a polymorphic many to many relationships. So if you want to manually handle tagging in the long term, I suggest designing that way.

Also, checkout spatie/laravel-tags package.
