Ошибка/ошибка с Ruby on Rails Tutorial Chapter 9

Question

Может ли кто-нибудь, кто сделал это упражнение, помочь мне?

Это мой первый опыт использования этого языка программирования и не так много, но мне нужно закончить до 10-й главы, что является окончательной оценкой.

Вот мой код:

require 'spec_helper' 

describe "User pages" do 

    subject { page } 

    describe "index" do 
    before do 
     sign_in FactoryGirl.create(:user) 
     FactoryGirl.create(:user, name: "Bob", email: "bob@example.com") 
     FactoryGirl.create(:user, name: "Ben", email: "ben@example.com") 
     visit users_path 
    end 

    it { should have_title('All users') } 
    it { should have_content('All users') } 

    it "should list each user" do 
     User.all.each do |user| 
     expect(page).to have_selector('li', text: user.name) 
     end 
    end 
    end 

    describe "profile page" do 
    let(:user) { FactoryGirl.create(:user) } 
    before { visit user_path(user) } 

    it { should have_content(user.name) } 
    it { should have_title(user.name) } 
    end 

    describe "signup page" do 
    before { visit signup_path } 

    it { should have_content('Sign up') } 
    it { should have_title(full_title('Sign up')) } 
    end 

    describe "signup" do 

    before { visit signup_path } 

    let(:submit) { "Create my account" } 

    describe "with invalid information" do 
     it "should not create a user" do 
     expect { click_button submit }.not_to change(User, :count) 
     end 
     describe "after submission" do 
     before { click_button submit } 

     it { should have_title('Sign up') } 
     it { should have_content('error') } 
     end 
    end 

    describe "with valid information" do 
     before do 
     fill_in "Name",   with: "Example User" 
     fill_in "Email",  with: "user@example.com" 
     fill_in "Password",  with: "foobar" 
     fill_in "Confirmation", with: "foobar" 
     end 

     it "should create a user" do 
     expect { click_button submit }.to change(User, :count).by(1) 
     end 

     describe "after saving the user" do 
     before { click_button submit } 
     let(:user) { User.find_by(email: 'user@example.com') } 

     it { should have_link('Sign out') } 
     it { should have_title(user.name) } 
     it { should have_selector('div.alert.alert-success', text: 'Welcome') } 
     end 
    end 
    end 

    describe "edit" do 
     let(:user) { FactoryGirl.create(:user) } 
    before do 
     sign_in user 
     visit edit_user_path(user) 

    describe "page" do 
     it { should have_content("Update your profile") } 
     it { should have_title("Edit user") } 
     it { should have_link('change', href: 'http://gravatar.com/emails') } 
    end 

    describe "with invalid information" do 
     before { click_button "Save changes" } 

     it { should have_content('error') } 
    end 
    end 

    describe "with valid information" do 
     let(:new_name) { "New Name" } 
     let(:new_email) { "new@example.com" } 
     before do 
     fill_in "Name",    with: new_name 
     fill_in "Email",   with: new_email 
     fill_in "Password",   with: user.password 
     fill_in "Confirm Password", with: user.password 
     click_button "Save changes" 
     end 

     it { should have_title(new_name) } 
     it { should have_selector('div.alert.alert-success') } 
     it { should have_link('Sign out', href: signout_path) } 
     specify { expect(user.reload.name).to eq new_name } 
     specify { expect(user.reload.email).to eq new_email } 
    end 
    end 
end 

Answer 1

Если код отформатирован так:

describe "edit" do 
    let(:user) { FactoryGirl.create(:user) } 
before do 
    sign_in user 
    visit edit_user_path(user) 

describe "page" do 
    it { should have_content("Update your profile") } 
    it { should have_title("Edit user") } 
    it { should have_link('change', href: 'http://gravatar.com/emails') } 
end 

я могу видеть, что это, вероятно, сломана без чтения какого-либо кода.

Все ли ваши блоки кода правильно закрыты? Не выглядит так!

Answer 2

В дополнении к незакрытым блокам, которые phoet указывала, которые вызывают ваш «неопределенный метод описание» ошибка, вы получаете ошибки в /app/views/users/index.html.erb строке 5. Ошибка undefined method `each' for nil:NilClass что означает, что есть переменный в этой строке, что вы 'do variable.each, но вы либо не устанавливаете эту переменную, либо когда вы ее устанавливаете, она устанавливается в nil.

В общем, путь для вас, чтобы успешно пройти через это, - это прочитать сообщения об ошибках и попытаться исправить то, о чем они жалуются. Если вы будете искать каждое сообщение об ошибке индивидуально, вы найдете проблемы переполнения стека по конкретной проблеме, которая вам поможет.
