In my User model I could have:
has_many :tasks
and in my Task model:
belongs_to :user
Then, supposing the foreign key 'user_id' was stored in the tasks table, I could use:
@user.tasks
My question is, how do I declare the has_many relationship such that I can refer to a User's Tasks as:
@user.jobs
... or ...
@user.foobars
Thanks a heap.
Give this a shot:
has_many :jobs, foreign_key: 'user_id', class_name: 'Task'
Note, that :as is used for polymorphic associations.
If you use has_many through, and want to alias:
has_many :alias_name, through: :model_name, source: :initial_name
(thanks for the correction Sami Birnbaum)
To complete @SamSaffron's answer :
You can use class_name with either foreign_key or inverse_of. I personally prefer the more abstract declarative, but it's really just a matter of taste :
class BlogPost
has_many :images, class_name: "BlogPostImage", inverse_of: :blog_post
end
and you need to make sure you have the belongs_to attribute on the child model:
class BlogPostImage
belongs_to :blog_post
end
