避免重复的“content_for”在视图中

发布于 2024-08-19 07:59:10 字数 352 浏览 13 评论 0原文

我的布局中放置了一个子菜单，该子菜单因控制器而异，但在每个控制器方法视图之间则不同。我目前正在做的事情如下：

<% content_for( :submenu ) do %>
    <%= render :partial => 'submenus/correct_submenu' %>
<% end %>

在方法的每个视图中

我的应用程序布局中都有这个

<%= yield :submenu %>

但是，这感觉有点重复，为每个视图执行此操作。每个控制器有什么方法可以做到这一点吗？

原文

I have a submenu placed in my layout wich differs from controller to controller, but not between each controllers method views. What I am currently doing is the following:

<% content_for( :submenu ) do %>
    <%= render :partial => 'submenus/correct_submenu' %>
<% end %>

In every view for a method

My applications layout then has this in it

<%= yield :submenu %>

However, this feels kind of repetitive, doing it for each view. Is there some way to do this per controller?

我的建议是为此制定一个约定，因此如果您有一个ProductsController，那么子菜单将为submenus/products_menu。这样您就可以编写一个如下所示的帮助程序：

def render_submenu
  content_for(:submenu) { render :partial => "submenus/#{controller.controller_name}_menu" }
end

然后您可以通过执行以下操作来调用它：

<%= render_submenu %>

然后您可以将其设为子菜单的默认 content_，并且仅在需要不同时才指定内容。

我希望这有帮助！

My suggest is to have a convention for this, so if you have a ProductsController then the submenu would be submenus/products_menu. This way you can write a helper that looks like:

def render_submenu
  content_for(:submenu) { render :partial => "submenus/#{controller.controller_name}_menu" }
end

You can then call this by doing:

<%= render_submenu %>

You could then make this the default content_for the submenus and only specify the content if it needs to be different.

I hope this helps!

使用嵌套布局将特定控制器的布局嵌套在应用程序布局下，方法是像这样创建一个文件：

# app/view/layouts/<controller_name>.html.erb
<% content_for( :submenu ) do %>
  <%= render :partial => 'submenus/correct_submenu' %>
<% end %>
<%= render template: "layouts/application" %>

使用这种方法，您不必修改一堆视图文件。

Use nested layouts to nest a specific controller's layout under the application layout, by creating a file like so:

# app/view/layouts/<controller_name>.html.erb
<% content_for( :submenu ) do %>
  <%= render :partial => 'submenus/correct_submenu' %>
<% end %>
<%= render template: "layouts/application" %>

With this method, you don't have to modify a bunch of view files.
