我是 Ruby on Rails 环境的新手,我能够解决的大多数问题,但我还没有找到解决这个问题的方法。
提供上下文:
- 使用导轨 (4.0.0)
- 使用守望者 (1.2.3)
- 使用设计(3.0.0)
- 使用 rolify (3.2.0)
- 使用康康 (1.6.10)
我的问题
当我使用Devise 的注册注册新用户时。:name 字段未添加到数据库中。查看服务器输出
用户模型(app/models/user.rb)
:name 包含在 attr_accessible 中。
class User < ActiveRecord::Base
rolify
# Include default devise modules. Others available are:
# :token_authenticatable, :confirmable,
# :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
# Setup accessible (or protected) attributes for your model
attr_accessible :role_ids, :as => :admin
attr_accessible :name, :email, :password, :password_confirmation, :remember_me
end
用户控制器(app/controllers/users_controller.rb)。
为了与 Rails 4 保持一致,我添加了 params 白名单,但这并没有解决问题。
class UsersController < ApplicationController
before_filter :authenticate_user!
def index
authorize! :index, @user, :message => 'Not authorized as an administrator.'
@users = User.all
end
def show
@user = User.find(params[:id])
end
def update
authorize! :update, @user, :message => 'Not authorized as an administrator.'
@user = User.find(params[:id])
if @user.update_attributes(params[:user], :as => :admin)
redirect_to users_path, :notice => "User updated."
else
redirect_to users_path, :alert => "Unable to update user."
end
end
def destroy
authorize! :destroy, @user, :message => 'Not authorized as an administrator.'
user = User.find(params[:id])
unless user == current_user
user.destroy
redirect_to users_path, :notice => "User deleted."
else
redirect_to users_path, :notice => "Can't delete yourself."
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_user
@user = User.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def user_params
params.require(:user).permit(:name, :email, :password, :password_confirmation, :remember_me)
end
end
Devise 的新注册视图(app/views/devise/registrations/new.html.erb)
<h2>Sign up</h2>
<%= simple_form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => {:class => 'form-vertical' }) do |f| %>
<%= f.error_notification %>
<%= display_base_errors resource %>
<%= f.input :name, :autofocus => true %>
<%= f.input :email, :required => true %>
<%= f.input :password, :required => true %>
<%= f.input :password_confirmation, :required => true %>
<%= f.button :submit, 'Sign up', :class => 'btn-primary' %>
<% end %>
<%= render "devise/shared/links" %>
应用程序控制器(app/controllers/application_controller.rb)
我遵循了有关强参数的说明,并包含了Devise的懒人方法
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_filter :configure_permitted_parameters, if: :devise_controller?
rescue_from CanCan::AccessDenied do |exception|
redirect_to root_path, :alert => exception.message
end
protected
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:name, :email) }
end
end

我的结论
毕竟,我相信问题出在设计的registration_controller,但我不确定如何访问控制器并纠正这个问题,或者这是否是问题所在。我希望这很简单,我只是忽略了它。
如果有人遇到此问题或可以对情况有所了解,将不胜感激。
干杯。
