玩！ 框架。 模板“包括”
[英]Play! framework. template “include”
问题描述
I'm planning my website structure as following: 
我正在计划我的网站结构如下：
- header.scala.html
- XXX
- footer.scala.html
now, instead of "xxx" there should be a specific page (ie "UsersView.scala.html"). 现在，而不是“xxx”应该有一个特定的页面（即“UsersView.scala.html”）。
what I need is to include (like with well-known languages) the source of the footer and the header into the the middle page's code. 我需要的是将页脚的来源和标题包含在（如知名语言）中间页面的代码中。
so my questions are: 所以我的问题是：
- How do you include a page in another with scala templating? 如何使用scala模板将页面包含在另一个页面中？
- Do you think it's a good paradigm for Play! 你认为这是Play的好范例吗？ framework based website? 基于框架的网站？

Just call another template like a method. 只需像方法一样调用另一个模板。 If you want to include footer.scala.html : 如果你想包括footer.scala.html ：
@footer()

A common pattern is to create a template that contains the boilerplate, and takes a parameter of type HTML. 常见的模式是创建包含样板的模板，并采用HTML类型的参数。 Let's say: 让我们说：
main.scala.html main.scala.html
@(content: HTML)
@header
// boilerplate
@content
// more boilerplate
@footer
In fact, you don't really need to separate out header and footer with this approach. 实际上，您并不需要使用此方法来分隔页眉和页脚。
Your UsersView.scala.html then looks like this: 您的UsersView.scala.html然后如下所示：
@main {
// all your users page html here.
}
You're wrapping the UsersView with main by passing it in as a parameter. 您通过将其作为参数传入包装UsersView。
You can see examples of this in the samples 您可以在示例中看到此示例
My usual main template is a little more involved and looks roughly like this: 我通常的主要模板更多涉及，看起来大致如下：
@(title: String)(headInsert: Html = Html.empty)(content: Html)(implicit user: Option[User] = None)
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>@title</title>
// bootstrap stuff here
@headInsert
</head>
<body>
@menu(user)
<div id="mainContainer" class="container">
@content
</div>
</body>
</html>
This way a template can pass in a head insert and title, and make a user available, as well as content of course. 这样，模板可以传入头部插入和标题，并使用户可用，当然还有内容。

Play provide a very convenient way to help implement that! Play提供了一种非常方便的方法来帮助实现它！
Layout part from official docs: 官方文档的布局部分：
First we have a base.html (that's we call in django -_-) 首先我们有一个base.html（我们称之为django -_-）
// views/main.scala.html
@(title: String)(content: Html)
<!DOCTYPE html>
<html>
<head>
<title>@title</title>
</head>
<body>
<section class="content">@content</section>
</body>
</html>
How to use the base.html? 如何使用base.html？
@main(title = "Home") {
<h1>Home page</h1>
}
