如何在带有 Playframework 2.2.x 的 build.sbt 中使用 templatesImport [英] How to use templatesImport in build.sbt with Playframework 2.2.x

问题描述

我必须在我的所有模板中导入一些可重用的块.

I have to import some reusable blocks in all my templates.

我在 appviewslocksheader.scala.html 中定义了一个块，以将该块包含在我的所有模板中(如 这里) 我在 build.sbt 中包含了这一行:

I have defined a block in appviewslocksheader.scala.html, to include the block in all my templates (as described here) I have included in build.sbt this line:

templatesImport += "views.html.blocks._"

但是我有这个编译错误:

but I have this compilation error:

[error] E:workspaceplay2testappviewsadminmain.scala.html:13: not found: value header
[error]         @header()
[error]          ^

块没有导入，我要改什么?

the block is not imported, what I have to change?

请注意，如果我使用 @import blocks._ 在模板中导入块，它会起作用.

note that if I import the block in the template with @import blocks._ it works.

推荐答案

我找到了解决问题的方法:在 build.sbt 中，我必须移动 templatesImport += "views.html.blocks._" 在 play.Project.playJavaSettings 行之后.

I have found the solution to my problem: In build.sbt I have to move the line templatesImport += "views.html.blocks._" after the line play.Project.playJavaSettings.

这是因为 playJavaSettings 使用默认导入初始化变量 templatesImport.

This is due to the fact that playJavaSettings initializes the variable templatesImport with the defaults imports.
