Question

저는이 문제에 대해 지금 당분간 고민 중이며 어떤 일이 일어나고 있는지 파악할 수 없습니다. 나는 Michael Hartl 's Rails 튜토리얼을 통해 자신의 방식대로 작업하고 있으며 일부 테스트에 문제가있는 것으로 나타났습니다. 그래서 여기 내 user_pages_spec.rb의

내가 releveant 것 밖에 모르겠어요하지만, 여기에 app/views/users/new.html.erb :

<% provide(:title, 'Sign up') %> 
<h1>Sign up</h1> 

<div class="row"> 
    <div class="span6 offset3"> 
    <%= form_for(@user) do |f| %> 
     <%= render 'shared/error_messages', object: f.object %> 
     <%= f.submit "Create my account", class: "btn btn-large btn-primary" %> 
    <% end %> 
    </div> 
</div> 

솔직히이 문제를 어디에서 찾을 지 100 % 확신하지 못합니다. 이 장에서 내가 한 가장 최근의 변화들과 함께 일어났습니다. 나는 모든 연습을하려고하는데 때로는 내가 편집해야 할 것들이 유사하기 때문에 나는 뭔가를 엉망으로 만들었는지 아니면 그냥 바보 같은 짓을했는지 모른다. 브라우저에서 응용 프로그램을 방문하고 "Sign up"링크를 클릭하여 새 사용자를 등록하면 ActionController :: ParameterMissing in UsersController # create라는 빨간색 레일 오류 페이지가 나타나지만 정확히 무엇을 의미하는지 모르겠습니다. . 나는 실제로 그 코드에 영향을 줄 수있는 코드를 변경했다고 생각하지는 않았지만 이전 연습을 완료하려고 시도 할 때 약간의 문제가 발생했습니다.

도움 주셔서 감사합니다. 이것은 나의 첫 번째 게시물이므로 에티켓/포맷팅에서 큰 실수를하지 않았기를 바랍니다. 평소처럼 비슷한 문제가있는 사람을 찾았지만 아무 것도 찾을 수 없었습니다.

편집 : 새 튜토리얼이 나왔을 때 완료되지 않았으므로이 튜토리얼의 이전 버전에서 작업하고 있다고 덧붙였습니다. 당신은 여기에서 그것을 발견 할 수있다 : http://rails-4-0.railstutorial.org/book/user_microposts

Answer 1

나는 대답이 꽤 간단하다고 생각한다. 그가 오류 렌더링 구성 요소를 추가하기를 원할 때 폼에서 모든 필드를 삭제 한 것처럼 보입니다. 가입 양식은 다음과 같아야합니다.

<% provide(:title, 'Sign up') %> 
<h1>Sign up</h1>  
<div class="row"> 
    <div class="span6 offset3"> 
    <%= form_for(@user) do |f| %> 
    <%= render 'shared/error_messages', object: f.object %> 

     <%= f.label :name %> 
     <%= f.text_field :name %> 

     <%= f.label :email %> 
     <%= f.text_field :email %> 

     <%= f.label :password %> 
     <%= f.password_field :password %> 

     <%= f.label :password_confirmation, "Confirmation" %> 
     <%= f.password_field :password_confirmation %> 

     <%= f.submit "Create my account", class: "btn btn-large btn-primary" %> 
    <% end %> 
    </div> 
</div>
