create unique profile page each user python

i using google appengine python , jinja2 , trying give each user in app unique url profile page can visited without logging in. here code far:

class profilepage(webapp2.requesthandler):   def get(self, profile_id):     user = user.get_by_id(profile_id)     #profile_id = unique field     if user:        #get posts user , render....        theid = user.theid        personalposts = db.gqlquery("select * post theid =:1 order created desc limit 30", theid)     else:         personalposts = none     global visits     logout = users.create_logout_url(self.request.uri)     currentuser = users.get_current_user()     self.render('profile.html', user = currentuser, visits = visits, logout=logout, personalposts=personalposts)  app = webapp2.wsgiapplication([('/', mainpage),                                ('/profile/([0-9]+)', profilepage),])

when try , test it gives me 404 error. suppose if code right might using wrong testing url. example if openid id: how can test out tried entering www.url.com/profile/https://www.google.com/accounts/o8/id?id=aitoawliloskgnwu5rutirtxug1l8rale45g-56 id="this part" put have:

url = www.url.com/profile/aitoawliloskgnwu5rutirtxug1l8rale45g-56

that's tried , didn't quite work. in advance help!

try regular expression:

r'^/profile/\w*?-(\d+)$'

though must tell bad idea!

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
