I am a newbie in rails. I am creating a new rails
application. Here I have 4 models.
The concept is
- Item belongs to User
- Item has many Tags
It means you have tags table will have item_id
- Item has many applications through tags
for above you must have some relations between application and tags
- Tags are hierarchical (i.e a tree structure, a child tag can be
related to a parent tag.)
tag belongs_to parent_tag :class_name => “Tag”, :foreign_key =>
You must have parent_id field in tags table.
If parent_tag is nil then you can identify tag as child_tag
Please help me, how to handle these Associations.
hope this will help !
