  • MySQLdb through proxy

    - by MihaiD
    I'm using the above mentioned Python lib to connect to a MySQL server. So far I've worked locally and all worked fine, until i realized I'll have to use my program in a network where all access goes through a proxy. Does anyone now how I can set the connections managed by that lib to use a proxy? Alternatively: do you know of another Python lib for MySQL that can handle this? I also have no idea if the if the proxy server will allow access to the standard MySQL port or how I can trick it to allow it. Help on this is also welcomed.

  • "cannot concatenate 'str' and 'list' objects" keeps coming up :(

    - by ratce003
    I'm writing a python program and passing in a html template but an error keeps coming up, "cannot concatenate 'str' and 'list' objects" here is is the program: #!/usr/bin/env python # -*- coding: UTF-8 -*- # enable debugging import cgi import cgitb cgitb.enable() def template(file, **vars): return open(file, 'r').read() % vars print "Content-type: text/html\n" print form = cgi.FieldStorage() # instantiate only once! num_1 = form.getfirst('num_1') num_2 = form.getfirst('num_2') int1r = str(num_1) int2r = str(num_2) def calc_range(int2r, int1r): start = range(int2r, int1r + 1) end = range(1, int2r) return start+end int1 = int(int1r) int2 = int(int2r) out_str = '' for i in range(0, int1): first_line_num = (int2 + i) % int1 if first_line_num == 0: first_line_num = int1 line = calc_range(first_line_num, int1) out_str += line print template('results.html', output=out_str, title="Latin Squares")

  • Django syncdb not making tables for my app

    - by Rosarch
    It used to work, and now it doesn't. python manage.py syncdb no longer makes tables for my app. From settings.py: INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'mysite.myapp', 'django.contrib.admin', ) What could I be doing wrong? The break appeared to coincide with editing this model in models.py, but that could be total coincidence. I commented out the lines I changed, and it still doesn't work. class MyUser(models.Model): user = models.ForeignKey(User, unique=True) takingReqSets = models.ManyToManyField(RequirementSet, blank=True) takingTerms = models.ManyToManyField(Term, blank=True) takingCourses = models.ManyToManyField(Course, through=TakingCourse, blank=True) school = models.ForeignKey(School) # minCreditsPerTerm = models.IntegerField(blank=True) # maxCreditsPerTerm = models.IntegerField(blank=True) # optimalCreditsPerTerm = models.IntegerField(blank=True) UPDATE: When I run python manage.py loadddata initial_data, it gives an error: DeserializationError: Invalid model identifier: myapp.SomeModel Loading this data had worked fine before. This error is thrown on the very first data object in the data file.

  • Appscript to write iTunes artwork

    - by Kartik Aiyer
    I'm trying to capture artwork from a pict file and embed into a track on iTunes using python appscript. I did something like this: imFile = open('/Users/kartikaiyer/temp.pict','r') data = imFile.read() it = app('iTunes') sel = it.current_track.get() sel.artworks[0].data_.set(data[513:]) I get an error OSERROR: -1731 MESSAGE: Unknown object Similar applescript code looks like this: tell application "iTunes" set the_artwork to read (POSIX file "/Users/kartikaiyer/temp.pict") from 513 as picture set data of artwork 1 of current track to the_artwork end tell I tried using ASTranslate but it never instantiates 'the_artwork' and then throws an error when there is a reference to the_artwork. Can anyone help. I'm new to appscript and python in general.

  • Building an extension framework for a Rails app

    - by obvio171
    I'm starting research on what I'd need in order to build a user-level plugin system (like Wordpress plugins) for a Rails app, so I'd appreciate some general pointers/advice. By user-level plugin I mean a package a user can extract into a folder and have it show up on an admin interface, allowing them to add some extra configuration and then activate it. What is the best way to go about doing this? Is there any other opensource project that does this already? What does Rails itself already offer for programmer-level plugins that could be leveraged? Any Rails plugins that could help me with this? A plugin would have to be able to: run its own migrations (with this? it's undocumented) have access to my models (plugins already do) have entry points for adding content to views (can be done with content_for and yield) replace entire views or partials (how?) provide its own admin and user-facing views (how?) create its own routes (or maybe just announce its presence and let me create the routes for it, to avoid plugins stepping on each other's toes) Anything else I'm missing? Also, is there a way to limit which tables/actions the plugin has access to concerning migrations and models, and also limit their access to routes (maybe letting them include, but not remove routes)? P.S.: I'll try to keep this updated, compiling stuff I figure out and relevant answers so as to have a sort of guide for others.

  • How to force PyYAML to load strings as unicode objects?

    - by Petr Viktorin
    The PyYAML package loads unmarked strings as either unicode or str objects, depending on their content. I would like to use unicode objects throughout my program (and, unfortunately, can't switch to Python 3 just yet). Is there an easy way to force PyYAML to always strings load unicode objects? I do not want to clutter my YAML with !!python/unicode tags. # Encoding: UTF-8 import yaml menu= u"""--- - spam - eggs - bacon - crème brûlée - spam """ print yaml.load(menu) Output: ['spam', 'eggs', 'bacon', u'cr\xe8me br\xfbl\xe9e', 'spam'] I would like: [u'spam', u'eggs', u'bacon', u'cr\xe8me br\xfbl\xe9e', u'spam']

  • Mocking Autofac's "Resolve" extension method with TypeMock

    - by Lockshopr
    I'm trying to mock an Autofac resolve, such as: using System; using Autofac; using TypeMock.ArrangeActAssert; class Program { static void Main(string[] args) { var inst = Isolate.Fake.Instance<IContainer>(); Isolate.Fake.StaticMethods(typeof(ResolutionExtensions), Members.ReturnNulls); Isolate.WhenCalled(() => inst.Resolve<IRubber>()).WillReturn(new BubbleGum()); Console.Out.WriteLine(inst.Resolve<IRubber>()); } } public interface IRubber {} public class BubbleGum : IRubber {} Coming from Moq, the syntax and exceptions from TypeMock confuse me a great deal. Having initially run this in a TestMethod, I kept getting an exception resembling "WhenCalled cannot be run without a complementing behavior". I tried defining behaviors for everyone and their mothers, but to no avail. Then I debug stepped through the test run, and saw that an actual exception was fired from Autofac: IRubber has not been registered. So it's obvious that the static Resolve function isn't being faked, and I can't get it to be faked, no matter how I go about hooking it up. Isolate.WhenCalled(() => ResolutionExtensions.Resolve<IRubber>(null)).WillReturn(new BubbleGum()); ... throws an exception from Autofac complaining that the IComponentContext cannot be null. Feeding it the presumably faked IContainer (or faking an IComponentContext instead) gets me back to the "IRubber not registered" error.

  • Downgrading to pyobjc 2.0 from pyobjc 2.2

    - by maxdj
    I accidentally installed pyobjc 2.2 with easy-install pyobjc, and it's causing problems: When I try to import it I get the error Incompatible library version: _objc.so requires version 10.0.0 or later, but libxml2.2.dylib provides version 9.0.0 I'm not interested in fixing that though, all I want is my pyobjc 2.0 back. I've tried removing pyobjc 2.2 and reinstalling python, and I've tried building 2.0 from the svn trunk (I get the error lipo: can't figure out the architecture of [random filename].out) I imagine there must be a good way of doing this but it escapes me. Any insight would be appreciated. Edit: Python 2.6 and OSX 10.5

  • why egrep's stdout did not go through pipe?

    - by ccfenix
    Hi, i got a weird problem regarding egrep and pipe I tried to filter a stream containing some lines who start with a topic name, such as "TICK:this is a tick message\n" When I try to use egrep to filter it : ./stream_generator | egrep 'TICK' | ./topic_processor It seems that the topic_processor never receives any messages However, when i use the following python script: ./stream_generator | python filter.py --topics TICK | ./topic_processor everything looks to be fine. I guess there need to be a 'flush' mechanism for egrep as well, is this correct? Can anyone here give me a clue? Thanks a million import sys from optparse import OptionParser if __name__ == '__main__': parser = OptionParser() parser.add_option("-m", "--topics", action="store", type="string", dest="topics") (opts, args) = parser.parse_args() topics = opts.topics.split(':') while True: s = sys.stdin.readline() for each in topics: if s[0:4] == each: sys.stdout.write(s) sys.stdout.flush()

  • Emacs shell output buffer height

    - by jimbo
    Hi , i have the following in my .emacs file(thanks to a SOer nikwin), which evaluates the current buffer content and displays the output in another buffer. (defun shell-compile () (interactive) (save-buffer) (shell-command (concat "python " (buffer-file-name)))) (add-hook 'python-mode-hook (lambda () (local-set-key (kbd "\C-c\C-c") 'shell-compile))) The problem is that the output window takes half the emacs screen. Is there any way to set the output windows's height to something smaller. I googled for 30mins or so and could not find anything that worked. Thanks in advance.

  • Ubuntu One Folder Sync Filter

    - by Andy Barlow
    Hi, I am trying to modify the Ubuntu One File syncing python scripts to not including things like .iso's. I have got as far as finding this file: /usr/share/pyshared/ubuntuone/u1sync/constants.py Inside is this piece of code: import re # the name of the directory u1sync uses to keep metadata about a mirror METADATA_DIR_NAME = u".ubuntuone-sync" # filenames to ignore SPECIAL_FILE_RE = re.compile(".*\\.(" "(u1)?partial|part|" "(u1)?conflict(\\.[0-9]+)?)$") How can I edit this last section (regex?) and make it ignore .iso files??? I'm fairly sure this is the place to put it! Pretty sure this is standard python action :) Any help would be appreciated. Thanks kindly. Andy

  • ANCOVA in Python with Scipy/Numpy stats

    - by Shax
    I would like to know a way of performing ANCOVA(analysis of covariance) using Python with scipy. It is basically a statistical comparison of regression lines. I know Python can do ANOVA and it can also do regression line fitting with Scipy.stats. I'm not sure how to put those together to get an effective ANCOVA though, if it is possible. Regards, Shax

  • Why am I getting 404 in Django?

    - by alex
    After installing this python Django module: http://code.google.com/p/django-compress/wiki/Installation I am getting 404's in my media static files. This Django module is supposed to "compress" the javascript/css files. That's why I'm getting 404 I guess. The problem is, I don't want this anymore. And when I installed this program, I did "python setup.py install" How do I install it? I just want to revert it back to normal so I don't get any 404 errors.

  • When I run Django on Dreamhost using SQLite, why do I get an OperationalError telling me that a tabl

    - by Paul D. Waite
    I had a Django site running on Dreamhost. Although I used SQLite when developing locally, I initially used MySQL on Dreamhost, because that’s what the wiki page said to do, and because if I’m using an ORM, I might as well take advantage of it by running against a different database. After a while, I switched the settings on the server to use SQLite, to make it easier to keep my development database in sync with the server one. python manage.py syncdb worked on the server, but when I tried to access the site, I got an OperationalError. The Django error page said that one of my tables didn’t exist. I checked the database using sqlite on the command line on the server, and using python manage.py shell, and both worked fine.

  • Getting readline to block on a FIFO

    - by Dan
    I create a fifo: mkfifo tofetch I run this python code: fetchlistfile = file("tofetch", "r") while 1: nextfetch = fetchlistfile.readline() print nextfetch It stalls on readline, as I would hope. I run: echo "test" > tofetch And my program doesn't stall anymore. It reads the line, and then continues looping forever. Why won't it stall again when there's no new data? I also tried looking on "not fetchlistfile.closed", I wouldn't mind reopening it after every write, but Python thinks the fifo is still open.

  • Spam in the VS2010 Extension Manager

    - by Alex DeLarge
    What's with all the spam (free trials and so on from Component Source & Telerik among others) in the VS 2010 Extensions Manager. Without going to the website there is no way to know whether a listing is free or trialware so, for me, the entire user experience of the Extensions Manager is ruined. Anyone else finding this? Is there a way of suppressing these? Alex...
