  • simply way to add another webapp framework to my project.

    - by zjm1126
    one webapp project has many url and i have to change this: ('/addTopic', AddTopic), ('/delTopic', DeleteTopic), ('/addPost', AddPost), ('/delPost', DeletePost), to this: ('/tribes/addTopic', AddTopic), ('/tribes/delTopic', DeleteTopic), ('/tribes/addPost', AddPost), ('/tribes/delPost', DeletePost), but ,if i add this to my project ,i have to change the url in every py file or html file , in django it can be this : urlpatterns = patterns('', (r'^articles/2003/$', 'news.views.special_case_2003')), ) it is easy to add the url of 'news' to my peoject, but does webapp has this ? thanks updated: (1) my main page url is : ('/', MainPage), ('/sign', Guestbook), (2) the url of a webapp project that i want to add is : ('/', MainPage), ('/logout', LogoutPage), ('/login_response', LoginHandler), and i want to change (1) to this: ('/', MainPage), ('/sign', Guestbook), ('/aa/', p2.MainPage), ('/aa/logout', p2.LogoutPage), ('/aa/login_response', p2.LoginHandler), so i have to change so many url like / to /aa/ , or change /logout to /aa/logout in py file and html file , that is a hard work so any simple way to do this ?

  • Chipmunk warning still present with --release

    - by Kaliber64
    I'm using Python27 on Windows 7 64-bit. I downloaded the source for Chipmunk 6.2.x and compiled Pymunk with --release and -c ming32. Almost zero problems. Lots of path not found cause I'm bad. All prints seem to have disappeared but I get spammed with EPA iteration warnings. I've seen a couple discussions but no solutions. Possible chipmunk betas to fix the float errors causing the double truths causing the warning. I picked the latest stable version I think. My program is seriously bogged down with all the prints. class NullDevice(): def write(self, s): pass sys.stdout=NullDevice() Does not disable the C prints .< Any help?

  • How to create a backup from SqlAlchemy?

    - by swilliams
    I'm writing a Pylons app, and am trying to create a simple backup system where every table is serialized and tarred up into a single file for an administrator to download, and use to restore the app should something bad happen. I can serialize my table data just fine using the SqlAlchemy serializer, and I can deserialize it fine as well, but I can't figure out how to commit those changes back to the database. In order to serialize my data I am doing this: from myproject.model.meta import Session from sqlalchemy.ext.serializer import loads, dumps q = Session.query(MyTable) serialized_data = dumps(q.all()) In order to test things out, I go ahead and truncation MyTable, and then attempt to restore using serialized_data: from myproject.model import meta restore_q = loads(serialized_data, meta.metadata, Session) This doesn't seem to do anything... I've tried calling a Session.commit after the fact, individually walking through all the objects in restore_q and adding them, but nothing seems to work. What am I missing? Or is there a better way to do what I'm aiming for? I don't want to shell out and directly touch the database, since SqlAlchemy supports different database engines.

  • Is there a better way of making numpy.argmin() ignore NaN values

    - by Dragan Chupacabrovic
    Hello Everybody, I want to get the index of the min value of a numpy array that contains NaNs and I want them ignored >>> a = array([ nan, 2.5, 3., nan, 4., 5.]) >>> a array([ NaN, 2.5, 3. , NaN, 4. , 5. ]) if I run argmin, it returns the index of the first NaN >>> a.argmin() 0 I substitute NaNs with Infs and then run argmin >>> a[isnan(a)] = Inf >>> a array([ Inf, 2.5, 3. , Inf, 4. , 5. ]) >>> a.argmin() 1 My dilemma is the following: I'd rather not change NaNs to Infs and then back after I'm done with argmin (since NaNs have a meaning later on in the code). Is there a better way to do this? There is also a question of what should the result be if all of the original values of a are NaN? In my implementation the answer is 0

  • Django db encoding

    - by realshadow
    Hey, I have a little problem with encoding. The data in db is ok, when I select the data in php its ok. Problem comes when I get the data and try to print it in the template, I get - Å port instead of Šport, etc. Everything is set to utf-8 - in settings.py, meta tags in template, db table and I even have unicode method specified for the model, but nothing seems to work. I am getting pretty hopeless here... Here is some code: class Category_info(models.Model): objtree_label_id = models.AutoField(primary_key = True) node_id = models.IntegerField(unique = True) language_id = models.IntegerField() label = models.CharField(max_length = 255) type_id = models.IntegerField() class Meta: db_table = 'objtree_labels' def __unicode__(self): return self.label I have even tried with return u"%s" % self.label. Here is the view: def categories_list(request): categories_list = Category.objects.filter(parent_id = 1, status = 1) paginator = Paginator(categories_list, 10) try: page = int(request.GET.get('page', 1)) except ValueError: page = 1 try: categories = paginator.page(page) except (EmptyPage, InvalidPage): categories = paginator.page(paginator.num_pages) return render_to_response('categories_list.html', {'categories': categories}) Maybe I am just blind and/or stupid, but it just doesnt work. So any help is appreciated, thanks in advance. Regards

  • How to preprocess a Django model field value before return?

    - by Satoru.Logic
    Hi, all. I have a Note model class like this: class Note(models.Model): author = models.ForeignKey(User, related_name='notes') content = NoteContentField(max_length=256) NoteContentField is a custom sub-class of CharField that override the to_python method in purpose of doing some twitter-text-conversion processing. class NoteContentField(models.CharField): __metaclass__ = models.SubfieldBase def to_python(self, value): value = super(NoteContentField, self).to_python(value) from ..utils import linkify return mark_safe(linkify(value)) However, this doesn't work. When I save a Note object like this: note = Note(author=request.use, content=form.cleaned_data['content']) The conversed value is saved into the database, which is not what I wanna see. Would you please tell me what's wrong with this? Thanks in advance.

  • Copy **kwargs to self?

    - by Mark
    Given class ValidationRule: def __init__(self, **kwargs): # code here Is there a way that I can define __init__ such that if I were to initialize the class with something like ValidationRule(other='email') then self.other would be "added" to class without having to explicitly name every possible kwarg?

  • Debugging IDAPython Scripts outside of IDAPro

    - by YaronK
    I'm kinda new to scripting for IDA - nevertheless, I've written a complex script I need to debug, as it is not working properly. It is composed of a few different files containing a few different classes. Writing line-by-line in the commandline is not effective for obvious reasons. Running a whole script from the File doesn't allow debugging. Is there a way of using the idc, idautils, idaapi not from within IDA? I've written the script on PyDev for Eclipse, I'm hoping for a way to run the scripts from within it. A similar question is, can the api classes I have mentioned work on idb files without IDA having them loaded? Thanks.

  • How to do call function after client finishes download from tornado web server?

    - by Shabbyrobe
    I would like to be able to run some cleanup functions if and only if the client successfully completes the download of a file I'm serving using Tornado. I installed the firefox throttle tool and had it slow the connection down to dialup speed and installed this handler to generate a bunch of rubbish random text: class CrapHandler(BaseHandler): def get(self, token): crap = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(100000)) self.write(crap) print "done" I get the following output from tornado immediately after making the request: done I 100524 19:45:45 web:772] 200 GET /123 (192.168.45.108) 195.10ms The client then plods along downloading for about 20 seconds. I expected that it would print "done" after the client was done. Also, if I do the following I get pretty much the same result: class CrapHandler(BaseHandler): @tornado.web.asynchronous def get(self, token): crap = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(100000)) self.write(crap) self.finish() print "done" Am I missing something fundamental here? Can tornado even support what I'm trying to do? If not, is there an alternative that does?

  • module "random" not found when building .exe from IronPython 2.6 script

    - by Graham
    I am using SharpDevelop to build an executable from my IronPython script. The only hitch is that my script has the line import random which works fine when I run the script through ipy.exe, but when I attempt to build and run an exe from the script in SharpDevelop, I always get the message: IronPython.Runtime.Exceptions.ImportException: No module named random Why isn't SharpDevelop 'seeing' random? How can I make it see it?

  • App Engine HTTP 500s

    - by pocoa
    This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application. I've handled all the situations, also DeadlineExceededError too. But sometimes I see these error messages in error logs. That request took about 10k ms, so it's not exceeded the limit too. But there is no other specific message about this error. All I know is that it returned HTTP 500. Is there anyone know the reason of these error messages? Thank you.

  • how to detect an escape sequence in a string

    - by mix
    Given a string named line whose raw version has this value: \rRAWSTRING how can I detect if it has the escape character \r? What I've tried is: if repr(line).startswith('\r'): blah... but it doesn't catch it. I also tried find, such as: if repr(line).find('\r') != -1: blah doesn't work either. What am I missing? thx! EDIT: thanks for all the replies and the corrections re terminolgy and sorry for the confusion. OK, if i do this print repr(line) then what it prints is: '\rSET ENABLE ACK\n' (including the single quotes). i have tried all the suggestions, including: line.startswith(r'\r') line.startswith('\\r') each of which returns False. also tried: line.find(r'\r') line.find('\\r') each of which returns -1

  • Storing a list of objects in GAE

    - by Dominic Bou-Samra
    I need to store some data that looks a little like this: xyz 123 abc 456 hij 678 rer 838 Now I would just store it as a traditional string and integer model, and put in the datastore. But the data changes regularly, and is ONLY relevant when looked at as a COLLECTION. So it needs to be store as either a list of lists, or a list of objects, both of which can't really be done without pickling as far as I know. Can anyone help? Even storing it as a text file may work :S

  • Disable autocomplete on textfield in Django?

    - by tau-neutrino
    Does anyone know how you can turn off autocompletion on a textfield in Django? For example, a form that I generate from my model has an input field for a credit card number. It is bad practice to leave autocompletion on. When making the form by hand, I'd add a autocomplete="off" statement, but how do you do it in Django and still retain the form validation?

  • Getting an entry before and after a given entry in a Django Queryset

    - by Vernon
    I am creating a simple blog as part of a website and I am getting stuck on something that I am assuming is simple. If I call any blog post, say by it's title, from a queryset, how can I get the entry before and after the post in it's published order. I can iterate over the whole thing, get the position of the entry I have and use that to call the one before and the one after. But that is a long bit of code for something that I am sure I can do more simply. What I want would be something like this: next_post = Posts.object.filter(title=current_title).order_by("-published")[-1] Of course because of the filter, it is not going to work, but just to give you the idea of what I am looking for.

  • Facebook Connect via Javascript doesn't close and doesn't pass session id

    - by ensnare
    I'm trying to authenticate users via Facebook Connect using a custom Javascript button: <form> <input type="button" value="Connect with Facebook" onclick="window.open('http://www.facebook.com/login.php?api_key=XXXXX&extern=1&fbconnect=1&req_perms=publish_stream,email&return_session=0&v=1.0&next=http%3A%2F%2Fwww.example.com%2Fxd_receiver.htm&fb_connect=1&cancel_url=http%3A%2F%2Fwww.example.com%2Fregister%2Fcancel', '_blank', 'top=442,width=480,height=460,resizable=yes', true)" onlogin='window.location="/register/step2"' /> </form> I am able to authenticate users. However after authentication, the popup window just stays open and the main window is not directed anywhere. In fact, it is the popup window that goes to "/register/step2" How can I get the login window to close as expected, and to pass the facebook session id to /register/step2? Thanks!
