polymorphicHasMany
Usage
A polymorphicHasMany
relationship is a one-to-many
relationship. This relationship is used when an entity can belong to multiple types of entities. The classic example for this type of relationship is Posts
, Videos
, and Comments
.
The first value passed to polymophicHasMany
is a WireBox mapping to the related entity.
The second value is a prefix
for the polymorphic type. A common convention where is to add able
to the end of the entity name, though this is not automatically done. In our example, this prefix is commentable
. This tells quick to look for a commentable_type
and a commentable_id
column in our Comment
entity. It stores our entity's mapping as the _type
and our entity's primary key value as the _id
.
The inverse of polymophicHasMany
is polymorphicBelongsTo
.
