[Grok-dev] grok.url & grok.application_url in viewlets etc.

[Christian Klinger]

Hi Cavemans,

in my new grok application i use pure Z3 viewlets.

I wan´t construct some urls in my viewlets.

Now the Problem:
How can i access the application_url from my grok
application in viewlets.

After searching in this ml i found some methods
for getting url´s.

grok.View.application_url()
grok.util.url

I think grok.View.application_url() is the perfect fit for my
needs but i don´t get theses methods working in my
viewlets.

Now i make a a little hack in my viewlets for getting the
application_url, i just copy the funktion application_url in my
viewlet and this seems to work. But i have a "not so good feeling"
with this.

Are there any cleaner solutions for this?

I think a utiliy for getting application based url is nicer.
So i could access the url´s from every non grok module i use.

Thanks for help.

Christian
