使用Omniauth和Devise为用户登录到Rails应用程序创建密码

Question

用户可以使用omniauth提供程序登录到我的Rails应用程序，但我想仅为具有密码的用户启用某些功能。

当用户使用omniauth凭证创建时，其密码为空。当我尝试为omniauth用户创建密码时，出现错误“当前密码不能为空”。

如何为具有“nil”作为其current_password的omniauth用户创建密码？

这是我目前有我的形式修改用户的密码：

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => { :method => :put }) do |f| %> 
    <%= devise_error_messages! %> 

    <% if current_user.password != nil %> 
      <div class="formField"><%= f.label :current_password, :class=>"label label-info " %> <br /> 
       <%= f.password_field :current_password %></div> 
    <% else %> 
      <%= f.hidden_field :current_password, :value => nil %> 
    <% end %> 

    <div class="formField"><%= f.label "New password", :class=>"label label-info" %> <br /> 
     <%= f.password_field :password, :autocomplete => "off" %> 
    </div> 

    <div class="formField"><%= f.label "New password confirmation", :class=>"label label-info" %><br /> 
     <%= f.password_field :password_confirmation %> 
    </div> 

    <div class="editAccountButtons"> 
     <%= f.submit "Update", :class=>"btn btn-small btn-info submitButton" %> 
    </div> 
<% end %> 

registrations_controller.rb

def update 
      @user = User.find(current_user.id) 
     successfully_updated = if needs_password?(@user, params) 
     Rails.logger.debug('updating with password') 
      @user.update_with_password(params[:user]) 
      else 
      # remove the virtual current_password attribute 
      if @user.provider.blank? 
        @user.update_without_password(params[:user]) 
       else 
       @user.update_with_password(params[:user]) 
       end 
     end 

     if successfully_updated 
       if params[:update_email] 
      set_flash_message :alert, :signed_up_but_unconfirmed 
      redirect_to after_update_path_for(@user) 
     else    
      set_flash_message :notice, :updated 
      sign_in @user, :bypass => true 
      redirect_to after_update_path_for(@user) 
     end 
     else 
      redirect_to :back, alert: resource.errors.full_messages[0] 
     end 
    end 

    # check if we need password to update user data 
    def needs_password?(user,params)   
     !params[:profile] && !user.password.blank? 
    end

这太问题回答我的问题！

Rails 3.2 Omniauth Devise - Add password - Skip current password

这是我的最终控制人：

def update 
     @user = User.find(current_user.id) 
     force_updated = false 

     successfully_updated = if needs_password?(@user, params) 
      Rails.logger.debug('updating with password') 
      @user.update_with_password(params[:user]) 
     else 
      if resource.update_attributes(params[resource_name]) 
       force_updated = true 
      end 
     end 

     if successfully_updated || force_updated 
      if params[:update_email] 
       set_flash_message :alert, :signed_up_but_unconfirmed 
       redirect_to after_update_path_for(@user) 
      else    
       set_flash_message :notice, :updated 
       sign_in @user, :bypass => true 
       redirect_to after_update_path_for(@user) 
      end 
     else 
      redirect_to :back, alert: resource.errors.full_messages[0] 
     end 
    end
