Easier way to pull associated records of has_many associated


Currently my User model has has_many groups and the Group model has_many

so is there any way to pulling all the folders like this.

Currently I have to loop like this and dump them in to array.

def user_folders user_folders = [] user_folders.push(self.folders.collect) self.groups.each do |group| user_folders.push(group.folders.collect) end user_folders = user_folders.flatten.uniq end

I get this error
“ActiveRecord::HasManyThroughSourceAssociationMacroError: Invalid source
reflection macro :has_many :through for has_many :group_folders,
:through => :groups. Use :source to specify the source reflection.”

User model

has_many :permissions has_many :folders, :through => :permissions has_many :members has_many :groups, :through => :members has_many :group_folders, :through => :groups, :source => :folders

Group model

has_many :members has_many :users, :through => :members has_many :permissions has_many :folders, :through => :permissions

So is there a easy way to pull user.groups.folders without looping
through each group and saving folder in a array?


If you want all folders belonging to all groups for a user, you can

user.groups.collect{|g| g.folders}.flatten.uniq

which will return all unique folders in an array.
