I am using Play 2.3.7 Java, and I am trying to render templates. I can get it to work, but only by using really ugly syntax. What I have that works so far is right here: https://gist.github.com/aaron235/c21866dd7bff0ba3fc0c

Clearly, having a bunch of curly-bracketed blocks of HTML isn't the best way to do this. My ideal 'home.scala.html' would look something like this: https://gist.github.com/aaron235/4f446dfa41feb7d02458

I'd like to have named parameters that parse into 'main.scala.html', but I can't find any resources that make sense, after thorough searching of SO, attempting to find information in "Play for Java" by Nicolas Leroux and Sietse de Kaper, and scouring the rest of the internet. Any help is appreciated.

In the template use cases documentation you can find a section devoted to your problem at the end of the Layout paragraph. Two different ways of declaring page-specific content blocks can be found there.

By applying information from docs your view is going to look like this:

@()

@title = {
<title>Welcome to MessageWorks.</title>
},

@stylesheets = {
<link type="text/css" rel="stylesheet" href="/styles/main.css" />
...
},

@javascripts = {
<script type="text/javascript" src="http://code.jquery.com/jquery-2.1.1.min.js"></script>
...
},

@page = {
<h1>MessageWorks</h1>
...
} 

@main(title)(stylesheets)(javascripts)(page)

You have to define each section as a reusable block and than simply pass them to the main template as parameters.

  • Thanks. I did kind of forget these things are actually executable Scala, that changes things. I found my own solution, I'll post it as a comment to my own post in addition to this in the hopes I can help someone some day. – user3140645 Dec 13 '14 at 11:18

I ended up finding a solution to my own problem. My setup ended up looking like this, which is more or less what my ideal solution would be. Essentially, I define 'main.scala.html' as a function that takes in those 4 arguments listed at the top, then in 'home.scala.html', I define 4 variables full of some HTML, and then pass them into my function 'main.scala.html'. Works like a charm, and I can parse different other files of simialr structure into main.
