That's the simplest way to do it - except
class Image < ActiveRecord::Base
has_and_belongs_to_many :tags
end
class Tag < ActiveRecord::Base
has_and_belongs_to_many :images
end
سؤال
Using rails 4.0.0 I'm trying to understand what "many to many, many to one, one to many etc" relationship i should use to do the following:
Image Table:
|file_name|description|
test.png test image
test2.jpg another test image
Tag table:
|tag_name|
funny
creative
cute
awesome
image_tag table:
|image_id|tag_id|
1, 1
1, 2
1, 3
2, 2
2, 4
etc..
What type of relationship should i use? This is what I'm considering using:
class Image < ActiveRecord::Base
has_and_belongs_to_many :image_tag
end
class Tag < ActiveRecord::Base
has_and_belongs_to_many :image
end
