[T5.2] Issues with Assets and Stylesheets
Today i migrated my application to T5.2-SNAPSHOT (i'm was obliged,
because spring-3.0 was required by thirdparty library). And i have few
notes about Asset handling.
First of all, when i found what i cannot reference Assets by static
urls (they was hardcoded in templates) i start thinking about
solution. I decide to create a Stack, and found what all inclusions of
script assets are placed before any script. This was a problem,
because there was external references (common for my company
libraries, which shouldn't be stored in my application by policy). My
Javascript is depends on this external libraries, so when i failed to
made inclusions in propper order i start to search way to hack. And
there is my solution:
Mapper<String, Asset> urlToAsset = new Mapper<String, Asset>() {
public Asset map(final String url) {
return new Asset() {
@Override
public String toClientURL() {
return url;
}
@Override
public Resource getResource() {
return
assetSource.getUnlocalizedAsset("classpath:media/temp.txt").getResource();
}
};
}
};
javaScriptStack =
Cf.x(F.flow("//js.externalhost.company.net/jquery/1.3.2/_jquery.js",
"//js.externalhost.company.net/2.1/common/js/_common.js").map(urlToAsset).toList()).plus(F.flow("${blogmon.assets}/js/_blogmon.js").map(pathToAsset).toList());
This works fine until combining scripts is turned off. There is no
actual request for assets occured, so temp.txt will never readed
(except cacher).
Solution in this situation will be to allow specify precendence of
imports (before or after script tags in templates) or to allow
including links to external assets.
Another suggestion is to be able to add initialization scripts in head
of document insted of end.
