我是Rails的新手,对路线有点困惑:
我有一个设备控制器:
#devices_controllers.rb
class DevicesController < ApplicationController
def index
@devices = Device.all
end
def show
@device = Device.find(params[:id])
end
def new
@device = Device.new
end
def create
@device = Device.new(params[:device])
if @device.save
flash[:notice] = "Successfully created device."
redirect_to @device
else
render :action => 'new'
end
end
def edit
@device = Device.find(params[:id])
end
def update
@device = Device.find(params[:id])
if @device.update_attributes(params[:device])
flash[:notice] = "Successfully updated device."
redirect_to @device
else
render :action => 'edit'
end
end
def destroy
@device = Device.find(params[:id])
@device.destroy
flash[:notice] = "Successfully destroyed device."
redirect_to devices_url
end
def custom_action
"Success"
end
我想通过以下网址访问“custom_action”操作:
http://foo.bar/devices/custom_action
我已将此行添加到我的routes.rb文件中:
match 'devices/custom_action' => 'devices#custom_action'
但是,当我在浏览器中尝试URL时,出现此错误:
ActiveRecord::RecordNotFound in DevicesController#show
Couldn't find Device with ID=custom_action
似乎是#show动作而不是#custom_action。如果没有提供用户ID,我转到http://foo.bar/devices/custom_action
,我希望它去#custom_action。
我已阅读Rails Routing from the Outside,但似乎仍无法解决问题。
答案 0 :(得分:3)
我认为问题可能是由于您定义路线的顺序。
我怀疑你resources :devices
中有routes.rb
。此外,我怀疑您已经在之后定义了自定义路线。如果在控制台/终端中键入rake routes
,您将看到已经为以下模式定义了路由:
GET /devices/:id
此路线是resources :devices
的乘积,优先于您的自定义路线。返回参考Edge Guides,特别是在1.1. Connecting URLs to Code中,它指出请求将被分派到 第一个 匹配路由。因此,一个简单的解决方法是在resources :devices
之前定义自定义路由。
