大家好,我是Rails的新手,如果我的问题很简单或很愚蠢,请理解我。我当前正在使用devise
gem,并且尝试将模式信息放入我的application.html.erb
中,以便模式信息始终显示在顶部,但是我得到的错误消息是
ApplicationController:Class的未定义局部变量或方法“ current_user”
我应该在哪里修复从Post.rb
中的Application.html.erb
调用记录的问题?感谢您的帮助!
Application.html.erb
<ul class="nav navbar-nav navbar-right">
<% if user_signed_in? %>
<li><%=link_to 'Sign out', destroy_user_session_path, method: 'delete' %></li>
<%=render "post_list", post_list: @post_list%> //I tried to call this
<% else %>
<li><%=link_to 'Sign in', new_user_session_path %></li>
<li><%=link_to 'Sign up', new_user_registration_path %></li>
<% end %>
</ul>
应用程序控制器
class ApplicationController < ActionController::Base
before_action :configure_permitted_parameters, if: :devise_controller?
protected
@post_list = Post.where(user_id: current_user).list?
def configure_permitted_parameters
devise_parameter_sanitizer.permit(:sign_up, keys: [:name])
devise_parameter_sanitizer.permit(:account_update, keys: [:name])
end
end
答案 0 :(得分:1)
这是您可以在current_user
中访问ApplicationController
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
def current_user_posts?
@post_list = Post.where(user_id: current_user).list? // current_user should work here.
end
end
