Question

I want to associate two models (Team and Member) by has_many :through, but returns NameError.
What am I missing?

Models

class Team < ActiveRecord::Base
  has_many :team_members
  has_many :members, :through => :team_members
end

class Member < ActiveRecord::Base
  has_many :team_members
  has_many :teams, :through => :team_members
end

class TeamMember < ActiveRecord::Base
  belongs_to :teams
  belongs_to :members
end

Database Tables

teams
members
teams_members

Errors

When I try to create new record with association, I got following errors.

@team = Team.new
@team.members
NameError: uninitialized constant Team::Members

Also when searching for existing record, these errors are thrown.

@team = Team.find(1)
@team.members # expecting to get existing records in members table
NameError: uninitialized constant Team::Members

Answer 1

The correct name for TeamMember table is team_members not teams_members
