GET() takes exactly 2 arguments (1 given)

[murat bilal]

Hi Everyone,

I am new to web.py and read this tutorial http://webpy.org/docs/0.3/tutorial

My code is
#!/usr/bin/env python
import web
render = web.template.render('templates/')
urls = {
'/.*','index'
}
class index:
def GET(self,name):
return render.index(name)

if __name__ == "__main__":
app = web.application(urls,globals())
app.run()

But when i go to the url like http://192.168.1.13:8080/Joe
I got his error <type 'exceptions.TypeError'> at /Joe

GET() takes exactly 2 arguments (1 given).

Any Ideas.Please help

I think your problem may be in the url mapping.  Try this:

'/(.*)', 'index'

Note the parens - I think that matters.

For what it's worth (your mileage may vary), I've found I'm not doing
very much argument passing on the URL once I got going past the
tutorials. I'm using web.data() and web.input() to get querystring or
post data the "old fashioned" way. For my jQuery ajax posts, I even
made a wrapper function:

def getAjaxArg(sArg, sDefault=""):
"""Picks out and returns a single value."""
data = uiGlobals.web.data()
dic = json.loads(data)

if dic.has_key(sArg):
return dic[sArg]
else:
return sDefault


and I call it like this:
xyz = getAjaxArg("myarg")

Yep, the ()'s are the regular expression capture directives, then those are automatically passed to the class function in question. I believe you can do multiples, but yeah, as Shannon says after you figure out the best method for passing that stuff around you realize there's better ways to do it.
