Question

我的模型用户有关系：

belongs_to :freelancer

和模型自由职业者：

belongs_to :user.

注册时使用设计。注册后，将使用user_id = current user.id自动创建具有Freelancer对象的新用户。在注册或登录并传入布局模板后，如何更好地获取@freelancer user_id = current user对象：

布局/ _user_panel.html.erb

<div class="user-panel_head">
    <%= link_to @freelancer, title: current_user.username, class: "user-panel__avatar active" do %>
      <%= image_tag "default/avatar.png", class: "avatario" %>
    <% end %>
    <div class="user-panel__side">
      <%= link_to current_user.username,  @freelancer, class: "user-panel__user-name" %>
      <span class="btn_drop icon_arrow_up" role="expand_menu_trigger"></span>
    </div>
</div>

Answer 1

此示例中current_user和@freelancer之间的区别是什么？您使用current_user中的数据来填充您的观点，这意味着他们是同一个对象，所以您不能link_to current_user, ...吗？

无论如何，为了解决你的问题 - 控制器中的实例变量会像模板和部分一样传递给布局。他们都被认为是观点，并且通常以类似的方式表现。因此，您需要在负责呈现页面的任何操作中在控制器中设置@freelancer。

对于Devise，您应该考虑覆盖after_sign_up_path_for方法并返回您希望用户在注册后重定向到的路由。

class Users::RegistrationsController < Devise::RegistrationsController

  # Resource is a User in this case
  def after_sign_up_path_for(resource)
      super(resource)

      user_path(resource)  # Return the path for the `users#show` route
    end
  end
end

因此，您要在与@freelancer相关联的控制器操作中指定user_path。同样的原则适用于Devise的SessionsController

Answer 2

试试这个，它会在Freelancer后立即创建sign_up。

class User < ActiveRecord::Base
   has_one :freelancer, dependent: :destroy
   before_create :set_freelancer

   def set_freelancer
    build_freelancer(id: self.id, user_id: self.id, email: self.email)
   end 
end

class Freelancer < ActiveRecord::Base
     belongs_to :user
end

如何在布局中看到变量？
