Question

我想通过使用Angular.js和Rails来显示卡片的索引。

这是我的代码。

# app/views/decks/show.html.erb
<div ng-controller="DeckCtrl">
  <form ng-submit="addCard()">
    <input type="text" ng-model="newCard.front" />
    <input type="submit" value="Add">
  </form>
  {{newCard.front}}
  <ul>
    <li ng-repeat="card in cards">
      {{card.front}}
    </li>
  </ul>
</div>

咖啡脚本

# app/assets/javascripts/decks.js.coffee
app = angular.module("Deck", ["ngResource"])

@DeckCtrl = ($scope, $resource) ->
  Card = $resource("/cards/:id", {id: "@id"}, {update: {method: "PUT"}})
  $scope.cards = Card.query()

  $scope.addCard = ->
    $scope.cards.push($scope.newCard)
    $scope.newCard = {}

CardsController。

class CardsController < ApplicationController
  respond_to :json
  def index
    respond_with Card.all
  end

  def show
    respond_with Card.find(params[:id])
  end

  def create
    respond_with Card.create(card_params)
  end

  def update
    respond_with Card.update(params[:id], card_params)
  end

  def destroy
    respond_with_Card.destroy(params[:id])
  end

  private
    # Never trust parameters from the scary internet, only allow the white list through.
    def card_params
      params.require(:card).permit(:front, :back, :tips, :cardtype, :deck_id, :box_number)
    end
end

addCard功能正常，但Card.query()给了我这个错误。

ActionController::UnknownFormat - ActionController::UnknownFormat:

看起来Angular.js发送HTML而非json，导致错误，是吗？如何删除此错误？

Answer 1

406表示服务器不支持客户端请求的格式。

angular发送的默认Accept标头为application/json, text/plain, */*。所以基本上它接受一切。只要我能看到它，$resource就不会改变任何东西。

有可能在您的应用程序中的某个位置设置了您的服务器无法处理的格式。

Answer 2

试试这个？

$resource("/cards/:id", {id: "@id"}, {update: {method: "PUT", responseType: 'json'}})

尝试Angular.js query（）函数时完成406 Not Acceptable错误
