Hey guys,

I have a Bookmark model.

I would like to have a List model. So my users can create Bookmark lists.

I created a List scaffold with this command

rails generate scaffold List title:string

  1. A List can have many bookmarks

  2. A Bookmark can have many lists.

Can someone help me to create List Bookmark relationship.? It would be awesome if you can give me some resources to learn.

Thankyou

Hi,

If list can have many bookmarks and bookmark can be included in many lists, you should use has_and_belongs_to_many, or has_many :through associations.

You can learn more in these articles

You should use a has_and_belongs_to_many association. Here is a nice code sample: http://guides.rubyonrails.org/association_basics.html#the-has-and-belongs-to-many-association

Don,t forget to create a middle table “bookmasks_lists”.

If the asociation has any attributes you shold use “has_many :through association” instead. http://guides.rubyonrails.org/association_basics.html#the-has-many-through-association
