我刚刚将rails从4.0升级到4.2,这似乎导致我的一个form_fors出错。现在,当我访问新视图时,我得到:
错误:
ActionController::UrlGenerationError at /billing/providers/new
No route matches {:action=>"show", :controller=>"billing/provider_agencies", :id=>nil} missing required keys: [:id]
查看(此行的错误):
= form_for @provider_agency, url: billing_provider_agency_path(@provider_agency) do |f|
...
路线:
namespace :billing do
resources :provider_agencies, path: "providers" do
resources :invoices
end
end
控制器:
class Billing::ProviderAgenciesController < BillingController
before_action :set_provider_agency, only: [:show, :edit, :update, :destroy]
def index
...
end
def show
@users = @provider_agency.users
end
def destroy
...
end
def new
@provider_agency = Agency::Provider.new
end
def create
...
end
def edit
...
end
def update
...
end
protected
def provider_agency_params
params.require(:agency_provider).permit(:id, :name,...
...
])
end
def set_provider_agency
@provider_agency = @agency.agencies.find(params[:id])
end
end
我必须在form_for中定义url,因为我在路由中命名资源的方式。定义form_for中的url用于在包括new的任何视图中工作。现在,新视图似乎在调用show动作,并查找尚未创建/保存的@provider_agency。要清楚,这打破了新观点,但所有其他观点仍然有效。
我回去检查提交,但这些文件都没有改变,当我升级到Rail 4.2时,错误就开始了。
非常感谢任何想法,谢谢!
编辑:
以下是我的佣金路线的相关部分:
billing_provider_agencies GET /billing/providers(.:format) billing/provider_agencies#index
POST /billing/providers(.:format) billing/provider_agencies#create
new_billing_provider_agency GET /billing/providers/new(.:format) billing/provider_agencies#new
edit_billing_provider_agency GET /billing/providers/:id/edit(.:format) billing/provider_agencies#edit
billing_provider_agency GET /billing/providers/:id(.:format) billing/provider_agencies#show
PATCH /billing/providers/:id(.:format) billing/provider_agencies#update
PUT /billing/providers/:id(.:format) billing/provider_agencies#update
DELETE /billing/providers/:id(.:format) billing/provider_agencies#destroy

我有类似的问题。
我修改了form_for语法。
对于嵌套模型,旧语法:
form_for(@child, url: parent_child_path(@parent,@child))
更新语法
form_for([@parent,@child])
对于独立模型
form_for(@model, url: model_path(@model))
到
form_for(@model)
