Question

我无法弄清楚为什么我的表单没有将params传递给注册控制器。我有一个注册表单，使用jquery和javascript作为登录表单。我的第二种形式（最后一种）应该通过注册信息发送到注册控制器。不幸的是，我持续得到错误的参数数量（0表示1）。我不确定我是如何不传递信息的，任何帮助都表示赞赏。

    <div id="part-2">

registrations_controller.rb

class RegistrationsController < ApplicationController
[![enter image description here][1]][1] def new
    end

    def create
        @user = User.create(sign_up_params)
        if @user.save
            log_in @user
            flash[:success] = "We Made it!"
        else
            flash[:error] = @user.errors
        end
    end

    private 

    def sign_up_params
        params.require.(:user).permit(:email, :username, :avatar, :password, :password_confirmation, :trump)
    end

end

Answer 1

在.之后删除params.require：

def sign_up_params
  params.require(:user).permit(:email, :username, :avatar, :password, :password_confirmation, :trump)
end

Answer 2

应该是这样的：

 def sign_up_params
        params.require(:user).permit(:email, :username, :avatar, :password, :password_confirmation, :trump)
 end

Answer 3

错误显示为wrong number of arguments(0 for 1)，因为您没有在require方法中传递任何参数，而是在开头括号前添加了.参数，你需要删除它，因为Ruby正在执行(:user)作为方法，但事实并非如此。修正错误，将错误更正为答案

中提到的 dp7

def sign_up_params
  params.require(:user).permit(:email, :username, :avatar, :password, :password_confirmation, :trump)
end

希望有所帮助！

没有使用form_for将params传递给action
