我正在使用 rails composer 来开发一个快速的基础应用程序。我设置了一个带有主页的 bootstrap-devise-pundit 应用程序(也尝试过 Home、User、About 选项 - 页面在 ../views/pages 中设置为静态)。主页是“访问者”控制器,并作为标准布局查看。Rails 作曲家将 gem high_voltage 用于附加页面(静态),将它们放置在 ../views/pages 文件夹中。我遇到问题的地方是添加我自己的模型/控制器/视图。不是因为他们不工作。我的问题是视图没有使用应用程序页眉/页脚呈现。“访客”页面确实如此。不知道为什么。我可能在这里缺少什么?
例如,
I create a model mymodel.rb in ../app/models
I create a controller mycontroller.rb in ../app/controllers
I create a view index.html.erb in ../app/views/mycontroller/
可以查询模型,查看呈现索引(显示和定义/创建的自定义操作)。但是,我没有得到应用程序标头(以及样式表/javascript 包含或页脚。
当然会很感激轻推...
谢谢
从 rails composer 默认创建的应用程序布局。

这是我的应用程序布局。我相信我确实对控制器有看法。但是,它在没有应用程序布局的情况下呈现。

这是访问者控制器和 canopy_aps 控制器
root@work:/home/hackerkatt/workspace/canopy_portal# cat app/controllers/visitors_controller.rb
class VisitorsController < ApplicationController
end
root@work:/home/hackerkatt/workspace/canopy_portal# cat app/controllers/canopy_aps_controller.rb
class CanopyApsController < ApplicationController
before_filter :authenticate_user!
def initialize
@apname = ''
end
def index
canopy_aps = Gestio.getAPList()
@canopy_aps = CanopyAPS.organize(canopy_aps)
end
def show
ip = int2IPOctet(params[:id])
@apip = ip
@apname = params[:apname]
@ap = CanopyAPS.getAPSubscribers(ip)
@reg_subs = @ap.count
end
def registered_sms
@canopy_aps = Gestio.getAPList()
@reg_subs = CanopyAPS.getRegSMCounts(@canopy_aps)
@totals = CanopyAPS.totalsByComp(@reg_subs)
end
end
为了完整起见,相关视图...

如果我将渲染布局:“应用程序”添加到操作,则会渲染应用程序布局,然后是操作视图。而且我必须将其添加到每个操作/方法中以获取要呈现的应用程序布局。在网络上发现的一些帖子建议在控制器顶部使用“布局”应用程序“,这对我不起作用。也值得注意。如果我向访问者控制器添加一个索引操作(它没有定义任何操作,因此呈现默认索引视图),应用程序布局渲染中断并且所有呈现的是访问者索引视图。我想了解这一点。
class CanopyApsController < ApplicationController
before_filter :authenticate_user!
def initialize
@apname = ''
end
def index
canopy_aps = Gestio.getAPList()
@canopy_aps = CanopyAPS.organize(canopy_aps)
render layout: "application"
end
def show
ip = int2IPOctet(params[:id])
@apip = ip
@apname = params[:apname]
@ap = CanopyAPS.getAPSubscribers(ip)
@reg_subs = @ap.count
render layout: "application"
end
end
