Ruby on rails 4 rspec未定义的方法`更新'；零级：零级

大家好，我有一个问题。我正在用rspec对控制器进行测试，当我测试方法删除和更新时，我得到了错误：

 1) TarefasController PATCH #update with valid attributes locates the requested @tarefa
     Failure/Error: if @tarefa.update(tarefa_params)

     NoMethodError:
       undefined method `update' for nil:NilClass
     # ./app/controllers/tarefas_controller.rb:35:in `update'
     # ./spec/controllers/tarefas_controller_spec.rb:82:in `block (4 levels) in <top (required)>'

我的控制器：

class TarefasController < ApplicationController

    before_filter :authenticate_user!

    def index
        @tarefas = current_user.tarefas.all.order(:data)
        @data = DateTime.now
    end

    def show
        @tarefa = Tarefa.find(params[:id])
    end

    def new
        @tarefa = Tarefa.new
        @data = DateTime.now.strftime("%Y%m%d%H%M") 
    end

    def edit
        @tarefa = current_user.tarefas.find_by(id: params[:id])
        @data = DateTime.now.strftime("%Y%m%d%H%M") 
    end

    def create
        @tarefa = current_user.tarefas.new(tarefa_params)
        if @tarefa.save
            redirect_to @tarefa
        else
            render 'new'
        end
    end

    def update
        @tarefa = current_user.tarefas.find_by(id: params[:id])
        if @tarefa.update(tarefa_params)
            redirect_to @tarefa
        else
            render 'edit'
        end

    end

    def destroy
        @tarefa = current_user.tarefas.find_by(id: params[:id])
        @tarefa.destroy
        redirect_to tarefas_path
    end

    def complete_index 
        @tarefas = current_user.tarefas.complete.order(:data)
    end

    def complete_update
        @tarefa = current_user.tarefas.find_by(id: params[:id])
        @tarefa.update(complete:true)
        @tarefa.update(data_complete:DateTime.now.strftime("%Y%m%d%H%M") )
    end

    def incomplete_task
        @tarefa = current_user.tarefas.find_by(id: params[:id])
        if @tarefa.update(data_tarefa_params)
            @tarefa.update(complete:false)
            redirect_to complete_index_tarefas_path
        end
    end

    def edit_complete_task
        @tarefa = current_user.tarefas.find_by(id: params[:id])
        @data = DateTime.now.strftime("%Y%m%d%H%M") 
    end

    private
    def tarefa_params
        params.require(:tarefa).permit(:titulo, :descricao, :data, :complete)
    end

    def data_tarefa_params
        params.require(:tarefa).permit(:data)
    end

end

我的规范/工厂/用户.rb

FactoryGirl.define do
  factory :user do
    email { Faker::Internet.email }
    password { Faker::Internet.password(8) }
  end
end

patch:update，id:@tarefa

=>

patch:update，id:@tarefa.id

Hmm。。。我更改了，但在您创建

@tarefa=create.时运行测试时，错误消息保持不变

你没有在那里分配

用户：当前用户

。我正在使用带有rspec的设备，我想它已经定义了当我调用login\u user时用户登录的方式，我没有进行完整的测试，我正在用完整的测试编辑上面的帖子是，但是你的“tarefa”属于另一个用户。您可以确保是否将

find_替换为（id:params[：id]）

到

find（params[：id]）

FactoryGirl.define do
  factory :tarefa do
    association :user
    titulo { Faker::Name.title }
    descricao { Faker::Name.title }
    data {Faker::Time.between(DateTime.now, DateTime.now + 365.days)}
  end
end

FactoryGirl.define do
  factory :user do
    email { Faker::Internet.email }
    password { Faker::Internet.password(8) }
  end
end
