RE: [Zope] URL quoting in python

2000-07-21 Thread Duncan Booth 



 I often create an external method for this...
 
 em:
 
 def url_quote(s):
import urllib
return urllib.quote_plus(s, safe='')
 
 Silly, but it works.
 
 I think the alternative is to hack the DT_Util.py module in the
 DocumentTemplate directory to expose urllib or a derived function.

Isn't an external method a bit overkill? It is possible to just create a 
DTML Method called url_quote where the body is:
dtml-var s url_quote

(making sure there is no whitespace before this line, and no 
newline after it.)

Then from any other DTML method you just call it remembering to 
pass in the parameter by name.

e.g. 
 dtml-call 
"RESPONSE.redirect(URL1+'?foo_bar='+url_quote(s=ufoobar))"

Thanks for the tip Duncan,

I find it strange that this utility function is not in the _ namepace...
time to make a trip to the Tracker. It seems like a url-encoding
function should be directly accessible from zope.

Thanks

Kapil

dependent on whether you want spaces coded as + or %20

How about doing the equivalent on html_quote in python?

Sorry, brain defect on my part: didn't notice the -call :(

I see someone alerady posted what I should have said...

 It also fails for dtml-return... It looks like url_quote is only applicable
 to dtml-var...which is sort of painful.

not really... how and what would you apply html_quote to in call and
return (return is slightly easier)

cheers,

RE: [Zope] URL quoting in python

2000-07-20 Thread Chris McDonough 

 Didn't happen for me (Zope 2.2b4).  I got
 Invalid attribute name, "url_quote", for tag dtml-call 
 "REQUEST.set('URL', 
URL2+'?action=Add Material 
 Infoproduct_number='+product_number)" url_quote,
 on line 195 of index_html
 
 It also fails for dtml-return... It looks like url_quote is 
 only applicable
 to dtml-var...which is sort of painful.

Considering dtml-call has no return value which can be url_quoted, it's
not all that surprising.  url_quote takes action on the value rendered.
Since there can by definition be nothing to render when using dtml-call,
url_quote can't be supported on it.
