Question

我正在创建第一个rails应用程序并且昨天一切正常。我今天在视图上创建了关联，玩家可以使用has_many和belongs_to进入团队页面。现在我无法创建一个新的播放器，因为它在PlayersController #create消息中不断给我一个ActiveModel :: ForbiddenAttributesError。

提取的来源（第27行）：

  def create
    @player = Player.create(params[:player])
    respond_to do |format|
      if @player.save

参数：

{"utf8"=>"✓",
 "authenticity_token"=>"uw5w2sOgNF6y3+Jv6kvTj3X/dV2+PAVo2/OyHinIirY=",
 "player"=>{"first_name"=>"test",
 "last_name"=>"",
 "address_1"=>"",
 "address_2"=>"",
 "city"=>"",
 "state"=>"",
 "zip"=>"",
 "phone_number"=>"",
 "email"=>"",
 "birthday"=>"",
 "position"=>"",
 "bio"=>"",
 "team"=>"",
 "team_id"=>"1",
 "number"=>""},
 "commit"=>"Create Player"}

我的玩家控制器是：

def创建 @player = Player.new（player_params）

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

Answer 1

您应该在控制器中使用此player_params方法，并使用它将params传递给模型操作（创建，更新）

class PlayersController
  ...
  def create
    @player = Player.create(player_params)
    ...
  end

  private

  def player_params
    allow = [:first_name, :last_name, :address_1, :address_2, :city, :state, :zip, :phone_number, :email, :birthday, :position, :bio, :team, :team_id, :number]
    params.require(:player).permit(allow)
  end
end

Answer 2

当我已经应用了params.require位时，我一直在寻找解决方案。因此，对于使用 cancan 的用户，您需要将此部分添加到ApplicationController：

请参阅：https://github.com/ryanb/cancan/issues/571

before_filter do
  resource = controller_name.singularize.to_sym
  method = "#{resource}_params"
  params[resource] &&= send(method) if respond_to?(method, true)
end

Answer 3

class PlayersController

   ...

 def create
     @player = Player.new(player_params)

   ...

  end

 private

 def player_params

   params.require(:player).permit(:first_name, :last_name, :address_1, :address_2, :city, :state, :zip, :phone_number, :email, :birthday, :position, :bio, :team, :team_id, :number)

   end

end

Answer 4

如果您使用的是Rails 4并且添加了player_params方法，请不要忘记将创建方法中的params[:player]更改为player_params。

PlayersController中的ActiveModel :: ForbiddenAttributesError #create
