T5: Multiple onActivate?
Hi all,
It appears that onActivate() cannot be overloaded in a single page class.
I'm hoping I just missed something and that conclusion is wrong. If not,
how are others handling URLs like:
"news/43" (43 = DB ID)
"new/breaking-story" (breaking-story=slug)
I'd like to avoid a single onActivate() that takes an Object. So, any help
would be much appreciated.
Thanks,
Kevin

In some ways I'd agree, in others I wouldn't. I'm finding cases where T5
really made some simple well-defined aspects from previous generations much
more difficult than they need be. These will be getting added to JIRA
though.
All in all though, I do like a lot of the improvements. I'll have to check
out Alexander's book I suppose as well, since the documentation is a bit
lacking at the moment.

Kevin,
On this process, T3 ->T4 ->T5, just keep in mind that Tapestry 5 is much
more simple.

On the surface, I'd like to preserve the bookmarks. Like I said though, I
could do that with URLRewrite -- not ideal, but guaranteed to work.
Digging further, I'm trying to wrap my head around how Tapestry resolves
page names in T5, having been a T3 then a T4 user. The problems I'm running
into seem like they really shouldn't be problems and should be a common case
that Tapestry should make easy to handle. So, I'm willing to give the
framework the benefit of the doubt and correct my understanding. If not,
that's fine, too. I'll make a mental note not to try to do these things or
reevaluate if it's to be my new framework of choice.
For what it's worth, I'm working on migrating an application from django to
T5. There are a variety of reasons for this, both technical and political.
Ultimately, I'd like to see Java and Tapestry be a suitable replacement for
the flexibility of Python and Django.

I don't know.
There have been some threads and I think JIRA issues over the months on
similar topics. They revolve around making Tapestry URL's friendly, and the
logic involved in having something like Order/EditOrder reduced down to
order/edit, and dealing with cases when the package name is the same as the
page name, or even worse, if a parameter looks like a page name.
A search for those threads and issues might give you some ideas.
Are you just trying to preserve bookmarks? Is this something where you
really need to code the logic to cope with the old URL's while migrating to
a new URL scheme?

That did help a bit. At least I know how multiple onActivate can work if I
need a variable number of context values. Unfortunately, it doesn't address
when you have the same number, but different type.
Likewise, I still haven't seen how to render to "index" pages inside
subpackages.

Re: T5: Multiple onActivate?

Hmm . . . Okay, that's what I was afraid of. Unfortunately, it's a port of
an existing app, so I'd like to preserve URL structure if possible. I
supposed URLRewrite could do the trick.
As a follow-up question, is there anyway to do the following:
"orders/43" (DB ID, caught through onActivate())
"orders/latest" (specified in com.example.www.pages.orders.Latest)
It looks like Tapestry will still try to pass "latest" through to
com.example.www.pages.Orders. I also couldn't figure out how to have a
"Start" class for each package, so that the first URL would actually map to
com.example.www.pages.orders.Start.
Is that doable, or do I have to work around it as well?
Thanks,
Kevin

RE: T5: Multiple onActivate?

For this use-case, I would suggest taking a string. If it matches a regex
(like a number pattern), then cast and do a db-lookup. Otherwise, do
whatever else you want to do.
Or you can use something like news/lookup/43 and
news/breaking/breaking-story to be more explicit.
