class RecipesController < ApplicationController
  def index
    @user = User.find(params[:user_id])
    @recipes = Recipe.all
 
    respond_to do |format|
      format.html
      format.json { render json: Recipe.where(user_id: params[:user_id]).featured }
    end
  end
  ...
end

我尝试为response.xhr？添加一个检查,如果它是一个AJAX请求,只渲染JSON,但这不起作用.

这是相关的Backbone代码.

# app/assets/javascripts/collections/recipe_list_.js.cofee
@App.Collections.RecipeList = Backbone.Collection.extend
  url: ->
    "/users/#{@userId}/recipes"
  model: window.App.Models.Recipe
  initialize: (opts) ->
    @userId = opts.userId
 
 
# app/assets/javascripts/app.js.coffee
$->
  urlAry = window.location.href.split('/')
  userId = urlAry[urlAry.length - 2]
  App = window.App
  App.recipeList = new App.Collections.RecipeList(userId: userId)
  App.recipeListView = new App.Views.RecipeListView
