Question

嗯，我是铁杆的新手，但不是新的铁路方式，我有一个错误，我不知道如何解决它。

我创建了控制器而不是视图。

控制器：

class ReclamacoesController < ApplicationController

    def new
       @reclamacao = Reclamacao.new
    end
end

以及视图＆gt; controllerName＆gt; new.html.erb。

下的视图

<%= form_for @reclamacao do |f| %>
    <%= f.text_field  :titulo %>
<% end %>

Reclamacao模型存在。

我也为它创建了资源路径。

resources :reclamacoes

所以，当我访问/ reclamacoes / new时会抛出异常。

NoMethodError in Reclamacoes#new 
undefined method `reclamacaos_path' for #<#<Class:0x00000001fc0660>:0x00000001fba850>

Extracted source (around line #1):
<%= form_for @reclamacao do |f| %>
    <%= f.text_field  :titulo %>
<% end %>

路线：

     reclamacoes GET    /reclamacoes(.:format)          reclamacoes#index
                 POST   /reclamacoes(.:format)          reclamacoes#create
   new_reclamaco GET    /reclamacoes/new(.:format)      reclamacoes#new
  edit_reclamaco GET    /reclamacoes/:id/edit(.:format) reclamacoes#edit
       reclamaco GET    /reclamacoes/:id(.:format)      reclamacoes#show
                 PATCH  /reclamacoes/:id(.:format)      reclamacoes#update
                 PUT    /reclamacoes/:id(.:format)      reclamacoes#update
                 DELETE /reclamacoes/:id(.:format)      reclamacoes#destroy

有什么问题？

Answer 1

Rails正试图自动猜测复数。问题是您的资源是reclamacao，其中Rails变为reclamacaos复数。但您已将其命名为reclamacoes

我建议更改名称或指示Rails使用更好的复数。以下是相关文章：How do I override rails naming conventions?

Answer 2

查看rake routes的输出。您会注意到拼写错误

reclamacoes    GET    /reclamacoes(.:format)          reclamacoes#index
               POST   /reclamacoes(.:format)          reclamacoes#create
new_reclamaco  GET    /reclamacoes/new(.:format)      reclamacoes#new
edit_reclamaco GET    /reclamacoes/:id/edit(.:format) reclamacoes#edit
reclamaco      GET    /reclamacoes/:id(.:format)      reclamacoes#show
               PATCH  /reclamacoes/:id(.:format)      reclamacoes#update
               PUT    /reclamacoes/:id(.:format)      reclamacoes#update
               DELETE /reclamacoes/:id(.:format)      reclamacoes#destroy

根据以上输出，正确的路径名称为reclamacoes path。

Rails强调Convention over Configuration，你的模型，视图和控制器中有不同的拼写。

存在的方法的NoMethodError
