Rails路由名称空间和表单

ruby-on-rails

Dex · 技术社区 · 15 年前

  namespace :businesses do
    resources :registration
  end

我的控制器位于business/registration\u controller的子目录中。

def new
  @business = Business.new
end

form_for @business do |f| ... 但我得到了以下错误:

No route matches {:controller=>"businesses", :action=>"create"}

重新启动了服务器,我也得到了:

undefined method 企业路径:0x10339bb20>`

如果有名称空间的路由,最好的方法是:

class Admin::BusinessesController < ApplicationController
  def new
    @business = Business.new
  end
end

namespace :admin do
  resources :businesses
end

观点:

form_for [:admin, @business] do |f|...

文件: http://guides.rubyonrails.org/form_helpers.html 第2.3.1节 处理名称空间

关于你的案子:

在路线.rb一切正常。在视图中,您应该显式地编写url,因为控制器中除了controller name之外还有其他变量:

form_for @business, :url => business_registration_path do |f|...

class Businesses::RegistrationController < ApplicationController
  def new
    @business = Business.new
  end
end

还有一句话:我不会为注册新业务创建注册控制器。我认为将业务相关的操作保留在business_controller中会更清楚。

实际上,我认为有更好的解决办法。

form_for [:admin, @business]

提供url的问题是,如果将表单抽象为部分视图,则需要处理“创建”和“更新”情况。它们指向不同的url,最后提供 @url
