Question

我有设置表单。我想make，这样如果密码字段为空，则更新其他属性。我也在使用 devise 。是否有一些有用的方法可以帮助我解决这个问题？

form.html.erb

<%= form_for(@user, :url => url_for(:controller => 'settings', :action => 'update')) do |f| %>

    <%= f.label :email, 'Email' %>
    <%= f.email_field :email %>

    <%= f.label :mobile, 'Mobile' %>
    <%= f.phone_field :mobile %>

    <%= f.label :current_password, "Current password" %>
    <%= f.password_field :current_password %>

    <%= f.label :password, "New Password" %>
    <%= f.password_field :password, :autocomplete => "off"  %>

    <%= f.label :password_confirmation, "Confirm New Password" %>
    <%= f.password_field :password_confirmation %>

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

user.rb

  validates :password, length: {minimum: 4}, on: :update, allow_blank: true

settings_controller.rb

  def update 
    @user = current_user

    if @user.update_attributes(user_params)
        sign_in(@user, :bypass => true)
        flash[:success] = "Settings were successfully updated"

        respond_to do |format|
          format.html {redirect_to :action=> :show}
        end
    else
        flash[:fail] = "Settings **was not updated**"
        respond_to do |format|
            format.html {render :action => :show }
        end
    end
  end

使用此：

  def update
    # For Rails 4
    account_update_params = devise_parameter_sanitizer.sanitize(:account_update)
    # For Rails 3
    # account_update_params = params[:user]

    # required for settings form to submit when password is left blank
    if account_update_params[:password].blank?
      account_update_params.delete("password")
      account_update_params.delete("password_confirmation")
    end

    @user = User.find(current_user.id)
    if @user.update_attributes(account_update_params)
      set_flash_message :notice, :updated
      # Sign in the user bypassing validation in case his password changed
      sign_in @user, :bypass => true
      redirect_to after_update_path_for(@user)
    else
      render "edit"
    end
  end

Answer 2

我也在使用devise并在admin命名空间中有一个从application_controller继承的users_controller，因为我想保持admin和user部分分开。以下事情对我有用。

在用户模型中

验证：password，：password_confirmation，presence：true，on :: create

在控制器的更新操作中

def update # ..... @user.update_without_password(users_params) # ...... end

使用和不使用密码更新用户设置。轨道
