Laravel - Relationships - Many To Many Polymorphic Table Structure

Many-to-many polymorphic relations are slightly more complicated than "morph one" and "morph many" relationships. For example, a Post model and Video model could share a polymorphic relation to a Tag model. Using a many-to-many polymorphic relation in this situation would allow your application to have a single table of unique tags that may be associated with posts or videos. First, let's examine the table structure required to build this relationship:

    
    posts
        id - integer
        name - string
    
    videos
        id - integer
        name - string
    
    tags
        id - integer
        name - string
    
    taggables
        tag_id - integer
        taggable_id - integer
        taggable_type - string
