Rspec Rails：找不到ID为ID /没有路线匹配的帖子

Question

我正在用rspec测试create action，它给了我：

ActiveRecord :: RecordNotFound：找不到带有'id'=：post_id的帖子

不知道为什么会这样，有什么建议吗？

规格：

describe CommentsController  do
  it "#create" do
    post1 = create(:post)
    post :create, comment: attributes_for(:comment, post_id: post1.id)
    p Comment.count
  end
end

创建动作：

 def create
    @comment = @post.comments.build(comment_params)
    @comment.user_id = current_user.id

    respond_to do |format|
      if @comment.save
        format.json { render json: @comment }
      end
    end
  end

行动前：

  before_action :authenticate_user!
  before_action :find_post, only: [:index, :create, :destroy]

路线：

  post_comments GET /posts/:post_id/comments(.:format)        comments#index
                POST   /posts/:post_id/comments(.:format)     comments#create
  post_comment  DELETE /posts/:post_id/comments/:id(.:format) comments#destroy

Answer 1

尝试这个：

describe CommentsController  do
  it "#create" do
    post1 = create(:post)
    post :create, { post_id: post1.id, comment: attributes_for(:comment, post_id: post1.id) }
    p Comment.count
  end
end

我想问题是您没有在参数中发送post_id 。

Answer 2

问题是您没有正确传递post_id 。 这样传递并在find_post方法中调试，参数如何到达那里。

describe CommentsController  do
  it "#create" do
    post1 = create(:post)
    post :create, { post_id: post1.id, comment: { comment_attributes_here } }
    p Comment.count
  end
end
