What's the best way to rename photos with a unique filename on the server as they are uploaded, using django? I want to make sure each name is used only once. Are there any pinax apps that can do this, perhaps with GUID? ...

I need to use __new__ inst...
Hi I'm planning to write a pluggable application in python (+qt4). However I have great concerns about security. The plugins should be powerful enough as to do whatever they like within the application (and as a further constraint there will be a signing process and a warning for the user when using such a plugin), but interacting with ...
Being new to Python, I decided to get some feedback on a class I'd written ASAP so I ran it against pylint. Is the message it gave "Warning: Method could be a function" telling me that it would be better to move this method out of the class because it doesn't use any instance variables? In c# I would make this a static method. What's the...
I am using SWIG to pass numpy arrays from Python to C++ code: %include "numpy.i" %init %{ import_array(); %} %apply (float* INPLACE_ARRAY1, int DIM1) {(float* data, int n)}; class Class { public: void test(float* data, int n) { //... } }; and in Python: c = Class() a = zeros(5) c.test(a) This works, but how can I pa...
I'm using PYML to construct a multiclass linear support vector machine (SVM). After training the SVM, I would like to be able to save the classifier, so that on subsequent runs I can use the classifier right away without retraining. Unfortunately, the .save() function is not implemented for that classifier, and attempting to pickle it (b...
I am attempting to write a game using livewires and pygame where I have a chef (only image I had, haha), avoid rocks that are falling from the sky. The rocks are supposed to fall in random places. I want it to be that 1 rock falls to begin with, then every time you successfully dodge a rock, 2 more rocks fall, until you lose. What I have...
hi there, are there any way to create an object form any class inside a numpy array?. Something like: a = zeros(4) for i in range(4): a[i]=Register() Thanks ...
Hi, i'm trying to build a facebook API client using python, code follows: import os import urllib2 import urllib import cookielib import hashlib import json USER = '' PASS = '' LOGIN = 'http://www.facebook.com/login.php?login_attempt=1' HOST = 'http://api.facebook.com/restserver.php' API_KEY = 'eca5c767f0e5b65942419574374c34a4' SECRET...
Hi I have this OSS Project called Monocaffe connections manager which uses the Gtk.VteTerminal widget from PyGTK. A nice feature is that it allows the users to send commands to different servers' consoles (cluster mode) using a Gtk.TextView for the input. The way I send key strokes to each Gtk.VteTerminal is by using the feed_child met...
I am just starting out learning pygame and livewires, and I'm trying to make a single-player pong game, where you just hit the ball, and it bounces around until it passes your paddle (located on the left side of the screen and controlled by the mouse), which makes you lose. I have the basic code, but the ball doesn't stay on the screen, ...
How should I resize an image with Python script so that it would automatically adjust the Height ratio to the Width used? I'm using the following code: def Do(Environment): # Resize App.Do( Environment, 'Resize', { 'AspectRatio': 1.33333, 'CurrentDimensionUnits': App.Constants.UnitsOfMeasure.Pixels, ...
I'm currently using regular expressions to search through RSS feeds to find if certain words and phrases are mentioned, and would then like to extract the text on either side of the match as well. For example: String = "This is an example sentence, it is for demonstration only" re.search("is", String) I'd like to know where the is was...
I have two servers - one Django, the other likely to be written in Python - and one is putting 'tasks' into a database and another is processing these tasks. They share a database, but I want the processor to react quickly to new tasks rather than polling periodically. Are there any straightforward ways for two Python servers to talk t...
Hi together, I have a scipy.sparse.dok_matrix (dimensions m x n), wanting to add a flat numpy-array with length m. for col in xrange(n): dense_array = ... dok_matrix[:,col] = dense_array However, this code raises an Exception in dok_matrix.__setitem__ when it tries to delete a non existing key (del self[(i,j)]). So, for now ...
Hi everybody, I've recently begun working on Django and now my app is nearing completion and i've begun to wonder about security and best-practices. I have view that generates a page and different functions in the page post AJAX requests to individual views. For example, I have a view called show_employees and I can delete and update e...
I've installed all apps in a project, then added a site in the sites section, and deleted example.com. Now Pages section in Django CMS 2.0 isn't working: it raises a DoesNotExist exception: Site matching query does not exist. at http://127.0.0.1:8000/admin/cms/page/ The section worked normally before I deleted the example.com site. In ...
I want to collapse or expand sub-sequences of a list e.g. ['A', 'B', 'D', 'E', 'H'] -> ['AB', 'DE', 'H'] and vice versa EDIT: the example above may cause misunderstanding. the following is better: e.g. ['foo', 'bar', 'wtf'] <-> ['baz', 'wtf'] currently I wrote some ugly code like: while True: for i, x in enumerate(s): if x ==...
My question is pretty much the same as this question, except that ALL relationships should be many-to-many. I have the following classes in my models.py (somewhat simplified): class Profile(models.Model): # Extending the built in User model user = models.ForeignKey(User, unique=True) birthday = models.DateField() class...
I want to have a twisted service (started via twistd) which listens to TCP/POST request on a specified port on a specified IP address. By now I have a twisted application which listens to port 8040 on localhost. It is running fine, but I want it to only listen to a certain IP address, say 10.0.0.78. How-to manage that? This is a snippet...
