Question

型号：

class User < ApplicationRecord
   has_many :posts
end

class Post < ApplicationRecord
  belongs_to :user
end

控制器：

class PostsController < ApplicationController
  def create
   @post = current_user.posts.creata(post_params)
  end

  def post_params
   params.require(:post).permit(:name,:user_id)
  end
end

RSpec.describe PostsController do
 describe "create post" do
  it "should create"
   user = create(:user)
   expect{
   post :create, params: { name: "new post", user_id: user.id }
   }.to change(Post,:count).by(1)
  end
 end

这个错误： ActionController的:: ParameterMissing： param丢失或值为空：post

在轨道5上，您需要通过整个参数结构。见下文：

Rails 4：

import urllib.request, urllib.parse, urllib.error
import json
import threading
import time

localtime = time.asctime( time.localtime(time.time()))



url = 'api'

uh = urllib.request.urlopen(url)
data = uh.read().decode()

js =json.loads(data)


def last_price():
  threading.Timer(1.0, last_price).start()
  print(js['last'])
  print(localtime)


last_price()

Rails 5：

post :create, post: { name: "new post" }

您的规范也缺少current_user存根：

post :create, params: { post: { name: "new post" } }

在rspec控制器中使用current_user创建帖子
