路由Rails中使用户名的网址：(Routing in Rails making the Usern

用户和注册模型（每个用户都有一个注册表） - 在我的Rails应用程序有设备型号是。

我想改变我的路线，这样，而不是：

的 “http：//本地主机：3000 /注册/ 3”

表明：

“HTTP：//本地主机：3000 / erinwalker”

所以我改变路线

match '/:name' => "registries#show"

而在我的控制器中的表演动作：

def show
@user = current_user
@user = User.find_by_name!(params[:name])
@registry = @user.registry

和它的作品，但是当我创建或现在先更新注册表，它说：

Couldn't find User with name = 
app/controllers/registries_controller.rb:21:in `show'

尽管演出行动工作？

所述注册控制器：类RegistriesController <ApplicationController中的before_filter：的authenticate_user！：除了=>：显示load_and_authorize_resource

# GET /registries
# GET /registries.json
def index
@registries = Registry.all
@user = current_user
respond_to do |format|
  format.html # index.html.erb
  format.json { render json: @registries }
end
end

# GET /registries/1
# GET /registries/1.json
def show
@user = current_user
@user = User.find_by_name!(params[:name])
@registry = @user.registry


respond_to do |format|
  format.html # show.html.erb
  format.json { render json: @registry }
end
end

# GET /registries/new
# GET /registries/new.json
def new
@registry = Registry.new
@user = current_user

respond_to do |format|
  format.html # new.html.erb
  format.json { render json: @registry }
end
end

# GET /registries/1/edit
def edit
@registry = Registry.find(params[:id])
@user = current_user
end

# POST /registries
# POST /registries.json
def create
@registry = current_user.build_registry(params[:registry])
@user = current_user

respond_to do |format|
  if @registry.save
    format.html { redirect_to @registry, notice: 'Registry was successfully created.' }
    format.json { render json: @registry, status: :created, location: @registry }
  else
    format.html { render action: "new" }
    format.json { render json: @registry.errors, status: :unprocessable_entity }
  end
end
end

# PUT /registries/1
# PUT /registries/1.json
def update
@registry = Registry.find(params[:id])
@user = current_user


respond_to do |format|
  if @registry.update_attributes(params[:registry])
    format.html { redirect_to @registry, notice: 'Registry was successfully updated.' }
    format.json { head :no_content }
  else
    format.html { render action: "edit" }
    format.json { render json: @registry.errors, status: :unprocessable_entity }
  end
end
end

我的所有路由：

Mystorkparty::Application.routes.draw do  

devise_for :users


resources :registries


root :to => "static_pages#home"

match '/home',    to: 'static_pages#home'

match '/:name' => "registries#show"

Answer 1:

当您创建或更新您的模型，您发送POST /registries或PUT /registries/1 。

但/registries是由您的最后一个规则匹配match '/:name' => "registries#show" ，因此请求命中show动作。

如果您运行rake routes ，你应该看到这样的事情：

                POST   /registries(.:format)                 registries#create
                PUT    /registries/:id(.:format)             registries#update
                DELETE /registries/:id(.:format)             registries#destroy
                       /:name(.:format)                      registries#show

您可以添加method参数的路线，这样它会hit show只能在GET请求。

match '/:name' => "registries#show", :via => :get

但仍有可能在未来的冲突。 举例来说，如果你有注册表名users 。 所以，它通常建议使用前缀（ match '/r/:name' ）或定义允许的名称的设定，或选择注册安全名。

PS我不认为load_and_authorize_resource会为您的工作show的默认操作。 因为它需要PARAMS [：ID]自动加载资源。
