Hello,
Im currently working with an application where I want to send a clean
command into the url without encoded url value strings, in order to
cleanly serve and parse the delivered values from url_for to a
javascript handling.
The need also came up as I didnt found a way to cleanly redirect to a
url generated by url_for - without implementing addional checkups to
serve data to the Jinja templating engine, but had to respond to client
interactions from within Javascript code.
Also the returned encoded url looks kindly strange for my taste and
doesnt suit to "modern" web application design - possible users might be
irritated by the url_encode(d) url strings.
Therefore I tried to implement a small patch to avoid the encoding of
urls, if I know that the returned data is made saint inside my
application when returned to the user.
I added a small change in werkzeug.routing in order to receive what I
wanted to do, but I can guess that this is by far not the most elegant
way to do, but it does work for me.
My custom url_for looks like this (when using it):
url_for('lookup_handle', doEncode=False, myCmd='someCommandValue')
The change is in werkzeug.routing from 729 to 744
try:
# check if the value "doEncode" is present
doEncode = query_vars['doEncode'] # doEncode = False
if doEncode != False: #check if the value is really set false
raise
del query_vars['doEncode']
commands = ''
for cmd in query_vars:
commands += query_vars[cmd]
url += '?'+commands
except:
# original werkzeug code part
url += '?' + url_encode(query_vars, self.map.charset,
sort=self.map.sort_parameters,
key=self.map.sort_key)
# original werkzeug code end
Perhaps this idea might be carried further and implemented further
version of Flask/Werkzeug.
Regards,
Jan Riechers
