Question

我一直在尝试从管理员更新用户，但在更新用户时要求我不要将密码字段留空并确认密码，我该如何解决？

PD：我正在为用户使用设计，这只有在我在管理员中打印用户并尝试更新用户记录时才会发生

enterprise.rb

class Enterprise < ApplicationRecord

   validates :name, :about, :address, :image, :municipality_id, :enterprise_tag_id, presence: true
   validates :name, uniqueness: true

end

enterprises_controller.rb

class EnterprisesController < ApplicationController

  def index
    @enterprise_tags = EnterpriseTag.all
      if params[:enterprise_tag_id].present?
        @enterprises = Enterprise.paginate(:page => params[:page], :per_page => 8).by_category(params[:enterprise_tag_id])
      else
        @enterprises = Enterprise.paginate(:page => params[:page], :per_page => 8)
      end
   end

  def show
    @enterprise = Enterprise.find(params[:id])
    @hash = Gmaps4rails.build_markers(@enterprise) do |enterprise, marker|
      marker.lat enterprise.latitude
      marker.lng enterprise.longitude
    end
  end

  def new
  end

  def edit
    @enterprise = Enterprise.find(params[:id])
  end

  def create
  end

  def update
    @enterprise = Enterprise.find(params[:id])

    respond_to do |format|
      if @enterprise.update(enterprise_params)
        format.html { redirect_to admin_dashboard_path, notice: 'La empresa fue actualizada' }
        format.js {}
        format.json { render :show, status: :ok, location: @enterprise }
      else
        format.html { render :edit }
        format.js {}
        format.json { render json: @enterprise.errors, status: :unprocessable_entity }
      end
    end
  end

  def destroy
    @enterprise = Enterprise.find(params[:id])
    @enterprise.destroy
    redirect_to admin_dashboard_path
  end

private

  def enterprise_params
    params.require(:enterprise).permit(:name, :password, :password_confirmation, :municipality_id, :enterprise_tag_id, :email, :address, :image, :about)

我可以用这个设计链接解决问题： https://github.com/plataformatec/devise/wiki/How-To%3a-Manage-users-through-a-CRUD-interface

由于其灵活性，设计很棒。在用户模型上执行基本的CRUD操作实际上与在Rails中为其他任何内容创建CRUD操作没有什么不同。

但要记住几件事：

请务必将resources :user放在devise_for :users路线下方。

由于注册路由和用户管理路由可能会发生冲突，因此您需要更改其中一个。您可以将设计放在特定前缀下：

devise_for :users, :path_prefix => 'my'
resources :users

或您的用户：

devise_for :users
scope "/admin" do
  resources :users
end

在您的UsersController中，如果它是空白的，您还需要删除params哈希的密码密钥。如果没有，Devise将无法验证。在您的更新方法中添加以下内容：

if params[:user][:password].blank?
  params[:user].delete(:password)
  params[:user].delete(:password_confirmation)
end

UsersController中的CRUD操作示例：

def destroy
  @user.destroy!

  respond_to do |format|
    format.json { respond_to_destroy(:ajax) }
    format.xml  { head :ok }
    format.html { respond_to_destroy(:html) }      
  end
end
