Play! framework. template "include"
提问by socksocket
I'm planning my website structure as following:
我计划我的网站结构如下：
- header.scala.html
- XXX
- footer.scala.html
- 标头.scala.html
- XXX
- 页脚.scala.html
now, instead of "xxx" there should be a specific page (i.e. "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.
现在，应该有一个特定的页面而不是“xxx”（即“UsersView.scala.html”）。
我需要的是将页脚和页眉的来源（与众所周知的语言一样）包含在中间页面的代码中。
so my questions are:
所以我的问题是：
- How do you include a page in another with scala templating?
- Do you think it's a good paradigm for Play! framework based website?
- 你如何使用 Scala 模板在另一个页面中包含一个页面？
- 你认为它是 Play 的一个很好的范例吗！基于框架的网站？

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

A common pattern is to create a template that contains the boilerplate, and takes a parameter of type HTML. Let's say:
一种常见的模式是创建一个包含样板的模板，并采用 HTML 类型的参数。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.
事实上，您并不真的需要使用这种方法将页眉和页脚分开。
Your UsersView.scala.html then looks like this:
你的 UsersView.scala.html 看起来像这样：
@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来使用 main 包装 UsersView。
You can see examples of this in the samples
您可以在示例中看到这方面的示例
My usual main template is a little more involved and looks roughly like this:
我常用的主模板稍微复杂一些，大致如下所示：
@(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.
通过这种方式，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这一点！
Layout part from official docs:
来自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（这是我们在django中调用的-_-）
// 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>
}
