rspec post:create action ArgumentError: unknown keyword: post答案

【问题标题】：rspec post:create action ArgumentError: unknown keyword: postrspec post:create action ArgumentError: unknown keyword: post
【发布时间】：2018-07-26 04:09:40
【问题描述】：

这是我的 FactoryBot 文件，格式为 post.rb

FactoryBot.define do
  factory :post do
    title 'Rspec Test'
    text  'test for attributes'
    user_id 1
    topic_id 1
  end
end

在 posts_controller_spec.rb 中，我有以下内容来测试创建后操作的用例

it 'creates a new customer' do
  post :create, post: attributes_for(:post)
  expect(Post.count).not_to eq(0)
end

我收到以下错误

$stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift) /Users/vignesh/assignment/bin/rails spec

我正在使用Rails 5.1.4

ruby 4.4.1

factory bot 4.0
rspec 3.4

谁能帮帮我

【解决方案1】：

虽然我使用的是 rspec 5.xxx，但我在 rspec 3.xxx 的教程中也遇到了同样类型的错误所以这是我认为可行的解决方案

it 'creates a new customer' do
  expect{ 
    post :create, params: { topic_id: @topic, post: attributes_for(:post)}
        }.to change(Post, :count).by(1)
end

这和我的代码有点相似。我的代码运行良好。希望你的也能工作

 describe 'Post #create' do
      before(:each) do
      end
      context 'with valid attributes' do
        it 'saves the new product in the database' do
          expect{
            post :create, params: { product: attributes_for(:product)}
          }.to change(Product, :count).by(1)
        end
      end
    end

【解决方案2】：

代码必须是这样的

 describe 'POST create' do
    it 'creates a new Post' do
      expect {
        post :create, params: {topic_id: @topic, post: @post_attributes}
      }.to change(Post, :count).by(1)
    end

现在可以了

【解决方案3】：

似乎不包括请求助手。

请求规范由 :type => :request 标记，或者如果您已设置 config.infer_spec_type_from_file_location！通过将它们放入规格/要求。

我必须在参数中传递帖子：attributes_for(:post)，就像这个帖子：create, params:{post: attributes_for(:post)}
