ruby-on-rails – 设计 – Omniauth – 如果用户通过Facebook登

我遇到的当前问题是如果他们通过Facebook注册,则在我的注册#edit视图中隐藏密码字段.作为两个宝石的新手我还在努力调整.因此,在设置必要的辅助方法时,我有点不知所措.

根据维基的指示,这是我的注册控制器的样子：

class RegistrationsController < Devise::RegistrationsController
  before_filter :configure_permitted_parameters,if: :devise_controller?

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

    successfully_updated = if needs_password?(@user,params)
      @user.update_with_password(devise_parameter_sanitizer.sanitize(:account_update))
    else
      # remove the virtual current_password attribute
      # update_without_password doesn't know how to ignore it
      params[:user].delete(:current_password)
      @user.update_without_password(devise_parameter_sanitizer.sanitize(:account_update))
    end

    if successfully_updated
      set_flash_message :notice,:updated
      # Sign in the user bypassing validation in case their password changed
      sign_in @user,:bypass => true
      redirect_to after_update_path_for(@user)
    else
      render "edit"
    end
  end

  private

  # check if we need password to update user data
  # ie if password or email was changed
  # extend this as needed
  def needs_password?(user,params)
    user.email != params[:user][:email] ||
      params[:user][:password].present? ||
      params[:user][:password_confirmation].present?
  end

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) do |u|
      u.permit(:first_name,:last_name,:email,:password,:password_confirmation)
    end
    devise_parameter_sanitizer.for(:account_update) do |u|
      u.permit(:first_name,:password_confirmation)
    end
  end
end

这是我的注册编辑视图：

<% provide :title,'Edit Profile' %>

<h2>Edit <%= resource_name.to_s.humanize %></h2>

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

  <div><%= f.label :first_name %><br />
  <%= f.text_field :first_name %></div>

  <div><%= f.label :last_name %><br />
  <%= f.text_field :last_name %></div>

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

  <% if devise_mapping.confirmable? && resource.pending_reconfirmation? %>
    <div>Currently waiting confirmation for: <%= resource.unconfirmed_email %></div>
  <% end %>

  <div><%= f.label :password %> <i>(leave blank if you don't want to change it)</i><br />
    <%= f.password_field :password,autocomplete: "off" %></div>

  <div><%= f.label :password_confirmation %><br />
    <%= f.password_field :password_confirmation,autocomplete: "off" %></div>

  <div><%= f.label :current_password %> <i>(we need your current password to confirm your changes)</i><br />
    <%= f.password_field :current_password,autocomplete: "off" %></div>

  <div><%= f.submit "Update" %></div>
<% end %>

UPDATE

经过一些广泛的研究后,我找到了一个question,它隐藏了输入字段(问题中倒数第二个评论).唯一的问题是,由于某种原因,它会触发密码验证错误,尽管它不存在…

<div>
    <%= f.label :first_name %><br />
    <%= f.text_field :first_name %>
  </div>

  <div>
    <%= f.label :last_name %><br />
    <%= f.text_field :last_name %>
  </div>

  <% if user_signed_in? && !current_user.provider == 'facebook' %>
    <div>
      <%= f.label :email %><br />
      <%= f.email_field :email %>
    </div>

    <% if devise_mapping.confirmable? && resource.pending_reconfirmation? %>
      <div>Currently waiting confirmation for: <%= resource.unconfirmed_email %></div>
    <% end %>

    <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 :current_password %> <i>(we need your current password to confirm your changes)</i><br />
      <%= f.password_field :current_password %>
    </div>
