Question

我想路由

[PUT] http:// foo /data/base_states/?id=8

到我的控制器，最好是这种定义：

`match '/data/base_state:id' => 'base_state#create_or_update', via: [:put]`

如何？

似乎有许多不同的方法来定义路线，文档有些缺乏。会对任何其他建议的语法（有效）感兴趣。

不知道为什么建议的路线不起作用，这是我的routes.rb和控制器......

配置/ routes.rb中

EntwineBe::Application.routes.draw do

  namespace :data, defaults: {format: :json} do
      resources :event_categories
      resources :state_categories
      resources :base_events
      resources :base_states

      match '/block/:bock' => 'block#show', via: [:get]  # curiously, this WORKS AS EXPECTED with GET http://foo/data/block/foo

      match '/base_state/:id' => 'base_states#create_or_update', via: [:put]
  end
end

app / controllers / data / base_states_controller.rb

class Data::BaseStatesController < ApplicationController
  before_action :set_base_state, only: [:show, :edit, :update, :destroy]

  def index
    @base_states = BaseState.all
  end

  def show
  end

  def new
    @base_state = BaseState.new
  end

  def edit
  end

  def create  # typical REST is that this is PUT
    @base_state = BaseState.new(base_state_params)

    respond_to do |format|
      if @base_state.save
        format.html { redirect_to @base_state, notice: 'Base state was successfully created.' }
        format.json { render action: 'show', status: :created, location: data_base_state_url(@base_state) }
      else
        format.html { render action: 'new' }
        format.json { render json: @base_state.errors, status: :unprocessable_entity }
      end
    end
  end

  def create_or_update
    logger.info "WTF"
  end

  def destroy
    @base_state.destroy
    respond_to do |format|
      format.html { redirect_to base_states_url }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_base_state
      @base_state = BaseState.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def base_state_params
      params.require(:base_state).permit(:foo, :bar)
    end
end

            data GET    /data/block/:block(.:format)          data/code_block#show {:format=>:json}
                 PUT    /data/base_state/:id(.:format)            data/base_states#create_or_update {:format=>:json}
                 PUT    /data/base_state:id(.:format)             base_state#create_or_update {:format=>:json}

示例调用

$.ajax({'type':'PUT', 'url':'/data/base_state?id=8'})
$.ajax({'type':'PUT', 'url':'/data/base_state/?id=8'})

$.ajax({'type':'PUT', 'url':'/data/base_state?id=8.json'}) // not that expect it to need / I want to have .json
$.ajax({'type':'PUT', 'url':'/data/base_state/?id=8.json'}) // not that expect it to need / I want to have .json

Answer 1

将defaults: {format: :json}添加到您的路线中。

match '/data/base_state:id' => 'base_state#create_or_update', via: [:put], defaults: {format: :json}

Answer 2

put '/data/base_state:id' => 'base_state#create_or_update', defaults: { format: :json }

Answer 3

put "data/base_state:id(.:format)" => 'base_state#create_or_update'

Answer 4

希望我对此并不太晚！

如果您的路线为/data/base_state/:id，那么您用来查看ID为8的匹配资源的网址为/data/base_state/8.json。

正如spas正确指出的那样，如果你在ajax调用dataType: 'json'中设置了正确的数据类型，那么你不需要在URL的末尾添加.json
