在Phoenix中对模板使用不同布局的正确方法 [英] Proper way to use different Layouts for Templates in Phoenix

问题描述

在每个Controller动作中更改模板布局以使用put_layout方法的正确/最简单的方法吗?一个简单的示例，希望为不同的控制器使用不同的布局似乎变得非常重复(如下所示)，因此感觉好像我在框架中缺少某些东西.

Is the proper/simplest way to change the Layout of a Template to use the put_layout method within each Controller action? A simple example of wanting a different Layout for different Controllers seems to become very repetitive (below) so it feels like I'm missing something within the framework.

defmodule MyPhoenix.AController do 
    use MyPhoenix.Web, :controller

    def pageOne(conn, _params) do
        conn
        |> put_layout("LayoutA.html")
        |> render "page1.html" 
    end

    def pageTwo(conn, _params) do 
        conn
        |> put_layout("LayoutA.html")
        |> render "page2.html" 
    end
end

defmodule MyPhoenix.BController do 
    use MyPhoenix.Web, :controller

    def pageOne(conn, _params) do
        conn
        |> put_layout("LayoutB.html")
        |> render "page1.html" 
    end

    def pageTwo(conn, _params) do 
        conn
        |> put_layout("LayoutB.html")
        |> render "page2.html" 
    end
end

推荐答案

我认为最好设置默认布局.

I think you might be best off by setting a default layout.

defmodule MyPhoenix.AController do 
    use MyPhoenix.Web, :controller

    plug :put_layout, "LayoutA.html"

    def pageOne(conn, _params) do
        render conn, "page1.html"
    end

    def pageTwo(conn, _params) do 
        render conn, "page2.html" 
    end
end

defmodule MyPhoenix.BController do 
    use MyPhoenix.Web, :controller

    plug :put_layout, "LayoutB.html"

    def pageOne(conn, _params) do
        render conn, "page1.html" 
    end

    def pageTwo(conn, _params) do 
        render conn, "page2.html"
    end
end
