ActiveModel::ForbiddenAttributesError Ruby

Question

我被这个错误困住了，我不知道出了什么问题。

class TicketsController < ApplicationController
  def new
  end

  def create
    @tickets = Newticket.new(params[:tickets])

    @tickets.save
    redirect_to @tickets
  end

  private

  def tickets_params
    params.require(tickets).permit(:title, :text)
  end
end

Answer 1

您必须将ticket_params 传递给new 方法

def create
    # your code
    @tickets = Newticket.new(params[:tickets])

    # you should use
    @tickets = Ticket.new(ticket_params) #if your model is named Ticket
    @tickets = Newticket.new(ticket_params) #if your model is named Newticket
    @tickets.save
    redirect_to @tickets
end

private
    def tickets_params
        params.require(:tickets).permit(:title, :text) # if your model is named Ticket
        params.require(:newtickets).permit(:title, :text) # if your model is named Newticket
    end
end

您有创建方法ticket_params 允许来自params 哈希的:tickets 值，并且您已经用permit 说在params[:tickets] 哈希对象中允许哪些键。您已输入:title, :text。您的问题是您使用的 params[:ticket] 没有任何允许的参数。

Answer 2

@tickets = Newticket.new(params[:tickets])

Newticket.new 那个是造成麻烦的人。我之前在生成控制器时定义了错误的方法，我称之为 Newticket，而我应该称之为门票。

感谢您的输入。
