使用 Rails 4 添加字段以设计注册 [英] Adding Fields To Devise Sign Up Using Rails 4

问题描述

首先，我是 Rails 的新手，所以我仍在掌握事情的窍门.

To start off, I'm new to rails, so I'm still getting the hang of things.

我正在尝试向 Devise 注册页面添加两个字段，一个名字字段和一个姓氏字段.我已经继续更改视图和控制器以尝试此操作.它们看起来像这样:

I'm attempting to add two fields to the Devise sign up page, a first name field and a last name field. I've gone ahead and changed the view and the controller in order to attempt this. They look like this:

控制器:

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception

  before_action :configure_devise_permitted_parameters, if: :devise_controller?

  protected

  def configure_devise_permitted_parameters
    registration_params = [:firstName, :lastName, :email, :password, :password_confirmation]

    if params[:action] == 'update'
      devise_parameter_sanitizer.for(:account_update) { 
        |u| u.permit(registration_params << :current_password)
    }
    elsif params[:action] == 'create'
      devise_parameter_sanitizer.for(:sign_up) { 
        |u| u.permit(registration_params) 
      }
    end
  end
end

查看:

<h2>Sign up</h2>

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>

  <div><%= f.label :email %><br />
  <%= f.email_field :email, :autofocus => true %></div>

  <div><%= f.label :password %><br />
  <%= f.password_field :password %></div>

  <div><%= f.label :password_confirmation %><br />
  <%= f.password_field :password_confirmation %></div>

  <div><%= f.label :firstName %><br />
  <%= f.fName_field :firstName %></div>

  <div><%= f.label :lastName %><br />
  <%= f.lName_field :lastName %></div>

  <div><%= f.submit "Sign up" %></div>
<% end %>
<%= render "devise/shared/links" %>

但是，当我去查看页面时出现此错误:

However, I get this error when I go to view the page:

undefined method `fName_field' for #<ActionView::Helpers::FormBuilder:0x00000003c89940>

我必须在哪里定义这些方法?或者它们是在其他地方自动定义的?

Where must I define those methods? or are they automatically defined somewhere else?

感谢您的帮助.

推荐答案

使用f.something"，您可以只定义表单中的字段类型.尝试类似

With "f.something" you can just define the type of the field in the form. Try something like

<%= f.text_field :lastName %>

这应该可行.

您可以在此处阅读有关可用字段类型的信息:http://apidock.com/rails/ActionView/Helpers/FormHelper/form_for
