playframework - Dynamic content in the root template in Play framework (Scala) -
i learning play framework & wondering how create dynamic sidebar/footer appear in root template & wouldn't need pass data explicitly when rendering every single view. read through the docs, , there nothing this.
in django create custom template tag this. there similar in play well? best / typical approach solve this?
how avoid passing parameters everywhere in play2? , http://jazzy.id.au/default/2012/10/26/passing_common_state_to_templates_in_play_framework.html quite helpful.
for example can have templates footer.scala.html, main.scala.html , header.scala.html.
main.scala.html can like:
@(title: string)(content: html)(implicit x: sometype) <!doctype html> <html> <head> <title>@title</title> <link rel="stylesheet" media="screen" href="@routes.assets.at("stylesheets/main.css")"> <link rel="shortcut icon" type="image/png" href="@routes.assets.at("images/favicon.png")"> <script src="@routes.assets.at("javascripts/jquery-1.9.0.min.js")" type="text/javascript"></script> </head> <body> @header() @* include header *@ @content @* resolve "the content" index.scala.html *@ @footer() @* include footer *@ </body> </html> and page template example index.scala.html:
@(message: string)(implicit x: sometype) @main("welcome play 2.1") { content } the footer or header can consume x: sometype implicit method parameters deliver dynamic content.
