Question

我刚刚开始第10章，刚好在图10.1之后。

我在迁移和测试之前尝试了rake db：reset：prepare命令，但是没有用。

这是我的错误，我在这里找不到类似的错误：

故障：

1) Micropost 
     Failure/Error: @micropost = Micropost.new(content: "Lorem ipsum", user_id: user_id)
     NameError:
       undefined local variable or method `user_id' for #<RSpec::Core::ExampleGroup::Nested_1:0x007fcfecc789b8>
     # ./spec/models/micropost_spec.rb:9:in `block (2 levels) in <top (required)>'

  2) Micropost 
     Failure/Error: @micropost = Micropost.new(content: "Lorem ipsum", user_id: user_id)
     NameError:
       undefined local variable or method `user_id' for #<RSpec::Core::ExampleGroup::Nested_1:0x007fcfecc8a000>
     # ./spec/models/micropost_spec.rb:9:in `block (2 levels) in <top (required)>'

Failed examples:

rspec ./spec/models/micropost_spec.rb:15 # Micropost 
rspec ./spec/models/micropost_spec.rb:14 # Micropost

这是我的代码：

文件的

： db / migrate / [我的唯一时间戳] _create_microposts.rb

class CreateMicroposts < ActiveRecord::Migration
  def change
    create_table :microposts do |t|
      t.string :content
      t.integer :user_id

      t.timestamps
    end

    add_index :microposts, [:user_id, :created_at]

  end
end

对于文件： spec / models / micropost_spec.rb

require 'spec_helper'

describe Micropost do
  # pending "add some examples to (or delete) #{__FILE__}"

  let(:user) { FactoryGirl.create(:user) }
  before do
    #This code is not correct, idiomatically
   @micropost = Micropost.new(content: "Lorem ipsum", user_id: user_id)
  end

  subject { @micropost }

  it { should respond_to(:content) }
  it { should respond_to(:user_id) }

end

PS所有我的测试都是绿色的。 10

Answer 1

也许

   @micropost = Micropost.new(content: "Lorem ipsum", user_id: user_id)

错了？ user_id（第二次提及，即价值）来自哪里？

可能是user.user_id或current_user.id

Answer 2

来自the tutorial的确切代码：

require 'spec_helper'

describe Micropost do

  let(:user) { FactoryGirl.create(:user) }
  before do
    # This code is not idiomatically correct.
    @micropost = Micropost.new(content: "Lorem ipsum", user_id: user.id)
  end

  subject { @micropost }

  it { should respond_to(:content) }
  it { should respond_to(:user_id) }
end

不是user_id: user_id而是user_id: user.id

RSpec - 未定义的局部变量或方法`user_id'用于＃
