[jira] Created: (TAPESTRY-2313) Make usage of expansion within
Asset injection and template definition
Make usage of expansion within Asset injection and template definition
----------------------------------------------------------------------
Key: TAPESTRY-2313
URL: https://issues.apache.org/jira/browse/TAPESTRY-2313
Project: Tapestry
Issue Type: Improvement
Components: tapestry-core
Affects Versions: 5.0
Environment: Any
Reporter: Massimo Lusetti
It would be great if we could provide a way to use Asset with a dynamic path, known only at runtime.
Typical usage is for asset relative to a product in a online shot where i got the id of the prodcut beeing displayed and want to display the relative image via Asset to benefit of caching and others.
For the records, now the problem is solved using and an action link as the src attribute of img tag and from the action event handler returning a StreamResposne.

Well the point here is not to discuss when or where to have an (apache
httpd) alias which point to the root directory... is how to make the
Asset facility works dynamically to point to the correct asset base on
the product specificied.
Let's say you'have a URL like this /product/218 which is the product
page with activate context 218 that show the product details for
product with ID 218, now i want to put an asset with the product image
lets say ${asset:dynamic:product.path} which is a relative path on the
filesystem which point to the subdir of a predefined root where i got
access to the image file or just using the id to query the db to get
the actual path of the image.
Regards

So.. outside the context and classpath.. wow.
So how is that accessed then? Like what would the url point to it and
who would handle it and return something?..
Or is he saying that the clients can access the filesystem directly.. so
just giving them a "file:///........" url is fine.
If that is the case, I already have a UrlAssetFactory that I can post
up. It allows you to create assets with a "url:" prefix, that just
return the url associated with them. Allowing absolute urls :
"url:http://www.google.com/" or "url:file:///etc/passwd"

Well the asset is actually outiside the context path and outisde the
classpath. The asset is simply on the filesystem.
Maybe you're right in term that this reqeust is too specific but it
could be useful to have a FilesystemAssetFactory configurable via a
Symbol

Well, I can't remember who wanted this functionality, of being able to
generate assets dynamically. That is actually done through the
AssetSource, which is backed by a list of AssetFactories. So the could
would look something like the following:
@Inject
private AssetSource source;
public Asset getMyDynamicAsset() {
return source.getAsset( null, "context:/blahblah"+blahblah+"blah", null );
}

You mean AssetFactory which compose the structure behind AssetSource service.

So.. you know you could get the AssetSource, and create the desired
Asset directly, whenever you like..

[jira] Commented: (TAPESTRY-2313) Make usage of expansion within
Asset injection and template definition
Posted by "Massimo Lusetti (JIRA)" <de...@tapestry.apache.org>.

Massimo Lusetti commented on TAPESTRY-2313:
-------------------------------------------
Maybe another way could be to use the action link event handler to return a url (relative) built on top of assets virtual folder. But that is problematic since you have to eventually deal with context prefix and others development configuration options, i don't know if this is easly handled.
After that the job is ended with a custom factory.

[jira] Closed: (TAPESTRY-2313) Make usage of expansion within Asset
injection and template definition
Posted by "Howard M. Lewis Ship (JIRA)" <de...@tapestry.apache.org>.

Resolution: Won't Fix
Assignee: Howard M. Lewis Ship
I'm really adverse to mixing and matching the different bindings; anything complicated should go in Java code.
The AssetSource can help with what you want, but isn't quite ideal; perhaps if it had an extra method or two for conveniently obtaining assets from the context. Worse, the same code that handles the asset: binding prefix also has to handle @Inject @Path private Asset foo (that is, the AssetObjectProvider inside the MasterObjectProvider chain of command). Expansions and symbols share the same syntax which would be very confusing (that ${...} is a symbol only for asset: or something along those lines).
You can instead inject the AssetFactory (with marker annotation @ContextProvider).
