强参数 不允许的参数

Question

我知道有很多关于这个问题的问题，但是在看了大约十几个之后，似乎没有一个是同一个问题。我有一个"行动"模型，我只是简单地尝试编辑和更新。（仅供参考，这不是嵌套表单，我没有使用 devise，这不是活动管理员问题......就像几乎所有关于这个主题的其他问题一样）。我得到了

错误：

unpermitted parameters: utf8, _method, authenticity_token when I do this.

Actions_controller中的动作参数：

def action_params
    params.permit(:id, :call_answered, :is_customer, :category_id, :actiontype_id, :why,   :reviewer_id, :reviewed, :spam, :lead)
end

如果我将其更改为：

    params.require(:action).permit(:id, :call_answered, :is_customer, :category_id, :actiontype_id, :why,   :reviewer_id, :reviewed, :spam, :lead)
end

比我得到以下错误（我找不到任何解决方案）：

undefined method `permit' for "update":String

操作控制器：

def edit
    @action = Action.find(params[:id])
    @actiontypes = Actiontype.all
    @categories = Category.all
    @lead_categories = @categories.where(lead: true)
    @user = current_user
    @reviewer = User.find(@action.reviewer_id) if @action.reviewed?
end
def update
  @action = Action.find(params[:id])
    if @action.update!(action_params)
      binding.pry
      flash[:success] = "Loop closed!"
      redirect_to '/closingloop/actions?reviewed=false'
    else
      flash[:danger] = "Something Went Wrong! The loop was not closed!"
      render :edit
    end 
end
def action_params
    params.permit(:id, :call_answered, :is_customer, :category_id, :actiontype_id, :why,   :reviewer_id, :reviewed, :spam, :lead)
end

这里的主要问题是，如果你有一个名为"action"的模型，默认情况下你的参数将以相同的方式命名，这与ActionController默认参数发生冲突。我想最简单的解决方案是重命名您的模型。
