我在rails中建立了一对多关联，但我的测试一直在因为外键没有正确设置而失败。我想知道是否有人有建议。
我有两个模型-轮班和用户。我希望一个轮班由一个用户“创建”。一个用户可以创建多个轮班。
测试失败
*在rota_spec中：*
it {should belong_to :creator}
Expected Rota to have a belongs_to association called creator (Rota does not have a creator_id foreign key.)
*在user_spec中*
it {should have_many :created_rotas}
Expected User to have a has_many association called created_rotas (Rota does not have a creator_id foreign key.)
Rota.rb
belongs_to :creator, :class_name => "User"
User.rb
has_many :created_rotas, :class_name => "Rota", :foreign_key => "creator_id"
迁移
class AddCreatorToRotas < ActiveRecord::Migration
def change
add_column :rotas, :creator_id, :string
end
end
