Hi everyone, i am new to this group, hope someone can help me.

Suppose a DB schema with the following tables: users, documents, sections, documents_sections_users

How can i implement the has_and_belongs_to_many here? Rails doesn't seem to extract the dependencies :\

Thanks everyone

Hi, It should be from what I guess (you need to give more details): class User < AR   has_and_belongs_to_many :documents end

class Document < AR   has_and_belongs_to_many :users   has_and_belongs_to_many :sections end

class Section < AR has_and_belongs_to_many :documents end

and the tables are users, documents, sections, documents_users, documents_sections
