Hi there,

is there somebody who could help me out with the correct query syntax?

The situation is the following:

MODELS:

user has_many :memberships

user has_many :groups,
              :through => :memberships,
              :source => :group

TABLES:

users:
- id

memberships:
- id
- user_id
- group_id
- accepted (true/false)

groups:
- id

=> What I need is the collection of groups ("@groups") for a user, but
only if the "memberships" have "true" in the column "accepted".

I started with something like this (but don't know how to fix the
conditions part):

@groups = @user.groups.find(:all, :conditions => { "the memberships must
have 'true' in the 'accepted' column" })

= ?", @user])

Hey Craig,

thanks for your answer! One question back though:

In your 'conditions' statement: doesn't "accepted" refer to the 'group'
table? I'm asking because the tricky part in my case is: "accepted"
refers to/exists only in the 'membership' table... (see above: the model
is: user has_many :groups, :through => :memberships, :source => :group)

You can use the :conditions option:

  has_many :accepted_groups, :through => :memberships, :source
=> :group,
    :conditions => ['memberships.accepted =?', true]
