[英]Rails 4 destroy action, undefined_method message_path
[英]“Undefined_method, did you mean [pluralised] path?” error message on form_with Rails 5.1.6, using resources
我敢肯定,這是一個基本的問題,但是令人尷尬的是,我幾天來一直在撞牆。 因此,我有一個名為“國家”的模型。
Routes.rb看起來像:
Rails.application.routes.draw do
resources :country
resources :references
get 'homepage/home'
end
country_controller.rb看起來像:
class CountryController < ApplicationController
before_action :set_country, only: [:show, :edit, :update, :destroy]
def new
@country = Country.new
end
def create
@country = Country.new(:name => params[:name], :metatitle => params[:metatitle], :metadescription => params[:metadescription], :ogtitle => params[:ogtitle], :ogdescription => params[:ogdescription], :abouthtml => params[:abouthtml])
if @country.save
redirect_to country_index_path, notice: 'Country was successfully created.'
else
redirect_to :new, notice: 'Something went wrong :('
end
end
def update
if @country.update
redirect_to country_index_path, notice: 'Country was successfully created.'
else
redirect_to :new, notice: 'Something went wrong :('
end
end
end
new.html是:
<%= render 'form', country: @country %>
_form.html.erb是
<div class="form">
<%= form_with(model: country, local: true) do |f| %>
<div class="form_element">
<%= f.label "Name" %>
<%= f.text_field :name %>
</div>
<div class="form_element">
<%= f.label "Meta Title" %>
<%= f.text_field :metatitle %>
</div>
<div class="form_element">
<%= f.label "Meta Description" %>
<%= f.text_field :metadescription %>
</div>
<div class="form_element">
<%= f.label "OG_Title" %>
<%= f.text_field :ogtitle %>
</div>
<div class="form_element">
<%= f.label "OG_Description" %>
<%= f.text_field :ogdescription %>
</div>
<div class="form_element">
<%= f.label "abouthtml" %>
<%= f.text_field "About (HTML)" %>
</div>
<%= f.submit %>
<% end %>
</div>
在/ country / new上,我收到一條錯誤消息,提示未定義“ countries_path”,我的意思是“ country_path”嗎? 我絕對不知道我哪里出了錯。
干杯! 麥克風
關於多元化。 routes
和controllers
都使用復數model
中單數。
# config/routes.rb
Rails.application.routes.draw do
resources :countries # <= HERE
resources :references
get 'homepage/home'
end
# apps/controllers/countries_controller.rb
class CountriesController < ApplicationController
# ...
end
另外,我知道這不是您的問題的一部分,但也許您會希望將create動作更新為:
def create
@country = Country.new(country_params)
if @country.save
redirect_to countries_path, notice: 'Country was successfully created.'
else
redirect_to :new, notice: 'Something went wrong :('
end
end
protected
def country_params
params.require(:country).permit(:name, :metatitle, :metadescription, :ogtitle, :ogdescription)
end
在routes.rb
您應該具有:
Rails.application.routes.draw do
resources :countries
end
加上您擁有的所有其他內容,更改是: resources :countries
應為復數形式
