设计配置
Devise configuration
我目前想用设计登录。在电子邮件和密码之上,我想要一个用户名。我生成了迁移:
class AddUsernameToBuyer < ActiveRecord::Migration
def change
add_column :buyers, :username, :string
add_index :buyers, :username, unique: true
end
end
我还在注册视图中添加了用户名:
<h2>Sign up</h2>
<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
<%= devise_error_messages! %>
<div class="field">
<%= f.label :username %> <br />
<%= f.text_field :username %>
</div>
<div class="field">
<%= f.label :email %><br />
<%= f.email_field :email, autofocus: true %>
</div>
<div class="field">
<%= f.label :password %>
<% if @validatable %>
<em>(<%= @minimum_password_length %> characters minimum)</em>
<% end %><br />
<%= f.password_field :password, autocomplete: "off" %>
</div>
<div class="field">
<%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation, autocomplete: "off" %>
</div>
<div class="actions">
<%= f.submit "Sign up" %>
</div>
<% end %>
<%= render "devise/shared/links" %>
然后我将应用程序控制器用户名作为允许参数输入:
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_permitted_parameters, if: :devise_controller?
protected
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username) }
end
def after_sign_up_path_for(resource)
redirect_to root_path
end
end
当我尝试注册时,我被重定向到:http://localhost:3000/buyers/sign_up
填写详细信息后,我点击注册,我希望自己被重定向到 root_page。然而,devise 将我重定向到 http://localhost:3000/buyers
,它告诉我,即使我添加了它,我也不能有一个空白的用户名。
我怎样才能改变这个behavior/fix呢?
您需要在 after_sign_in_path_for(resource)
中生成 url。试试下面的代码。
def after_sign_in_path_for(resource)
root_path
end
要重定向,您需要将 after_sign_up_path_for
放入 RegistrationsController
。首先创建它以覆盖 Devise
的本机控制器。
class RegistrationsController < Devise::RegistrationsController
protected
def after_sign_up_path_for(resource)
root_path
end
end
