Question

我目前在本教程的清单10.32和10.33之间：http://ruby.railstutorial.org/chapters/user-microposts#sec-manipulating_microposts

我在运行测试时遇到了问题。输出如下：

Failures:

  1) Micropost pages micropost creation with invalid information should not create a micropost
     Failure/Error: expect { click_button "Post" }.not_to change(Micropost, :count)
     ActionController::ParameterMissing:
       param not found: micropost
     # ./app/controllers/microposts_controller.rb:23:in `micropost_params'

     # ./spec/requests/micropost_pages_spec.rb:16:in `block (4 levels) in <top (required)>'

  2) Micropost pages micropost creation with invalid information error messages

  3) Micropost pages micropost creation with valid information should create a micropost

Finished in 0.56491 seconds
3 examples, 3 failures

Failed examples:

rspec ./spec/requests/micropost_pages_spec.rb:15 # Micropost pages micropost creation with invalid information should not create a micropost
rspec ./spec/requests/micropost_pages_spec.rb:21 # Micropost pages micropost creation with invalid information error messages 
rspec ./spec/requests/micropost_pages_spec.rb:28 # Micropost pages micropost creation with valid information should create a micropost

这是目前失败的测试：

require 'spec_helper'

describe "Micropost pages" do

    subject { page }

    let(:user) { FactoryGirl.create(:user) }
    before { sign_in user }

    describe "micropost creation" do
        before { visit root_path }

        describe "with invalid information" do

            it "should not create a micropost" do
                expect { click_button "Post" }.not_to change(Micropost, :count)
            end

            describe "error messages" do
                before { click_button "Post" }
                it { should have_content('error') }
            end
        end

        describe "with valid information" do

            before { fill_in 'micropost_content', with: "Lorem ipsum" }
            it "should create a micropost" do
                expect { click_button "Post" }.to change(Micropost, :count).by(1)
            end
        end
    end

end

这意味着@micropost变量显然没有设置，但它是在静态页面控制器中设置的。我已经检查了一段时间，现在确实发现了与教程的差异，但没有成功找到任何。

有没有人看到这个问题？

问题是这里缺少'='标志：

<%= f.text_area :content, placeholder: "Compose new micropost..." %>
