我想要測試一些協會與RSpec的,但我得到這些故障:測試協會使用RSpec:類別沒有POST_ID外鍵
Category
Failure/Error: it {should belong_to :post}
Expected Category to have a belongs_to association called post (Category does not have a post_id foreign key.)
# ./spec/models/category_spec.rb:7:in `block (2 levels) in <top (required)>'
Post
Failure/Error: it {should have_one (:category)}
Expected Post to have a has_one association called category (Category does not have a post_id foreign key.)
# ./spec/models/post_spec.rb:8:in `block (2 levels) in <top (required)>'
這裏是我的模型:
class Post < ActiveRecord::Base
has_one :category
validates_presence_of :author, :category, :post
end
class Category < ActiveRecord::Base
belongs_to :post
validates_presence_of :name
end
和我的測試:
require 'spec_helper'
describe Post do
it {should validate_presence_of(:author)}
it {should validate_presence_of(:post)}
it {should validate_presence_of(:cathegory)}
it {should have_one (:category)}
end
describe Category do
it {should validate_presence_of :name}
it {should belong_to :post}
end
和我的方案
ActiveRecord::Schema.define(:version => 20121118131441) do
create_table "categories", :force => true do |t|
t.string "name"
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
t.integer "post_id"
end
create_table "posts", :force => true do |t|
t.string "author"
t.string "cathegory"
t.text "post"
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
t.integer "category_id"
end
end
有沒有人知道發生了什麼事?
你可以發佈你的模式嗎? –
對於has_one/belongs_to,您不需要雙方的按鍵我會說它應該發佈belongs_to類別(並有一個category_id列),而類別has_many帖子。 –
