  • module compiled with swig not found by python

    - by openbas
    Hello, I've a problem with SWIG and python. I've a c-class that compiles correctly, but the python script says it can't find the module. I compile with: swig -c++ -python codes/codes.i g++ -c -Wall -O4 -fPIC -pedantic codes/*.cc g++ -I/usr/include/python2.6 -shared codes/codes_wrap.cxx *.o -o _codes.so This gives me a _codes.so file, as I would expect, but then I have this python file: import sys import codes (rest of the code omitted) It gives me: Traceback (most recent call last): File "script.py", line 3, in <module> import codes ImportError: No module named codes According to http://www.swig.org/Doc1.3/Introduction.html#Introduction_nn8 this is all I should have to do... The files are in the same directory, so the path should not be a problem ?

  • Django crash without message

    - by schneck
    Hi there, I have a Django-project which was running fine, until I made "some changes" I don't remember exactly. Since that point, on every request, my project crashes silently: $ ./manage.py runserver -v2 Validating models... 0 errors found Django version 1.1.1, using settings 'src.settings' Development server is running at http://127.0.0.1:8000/ Quit the server with CONTROL-C. After I requested a page (admin oder frontend), it returns to the prompt. I did not find any other option to get verbose output than -v2 - is there any logfile I can use? I'm using Django 1.1.1 on a Mac OS X 10.6 with virtualenv, Python 2.6 Thanks a lot.

  • Fabfiles With Command Line Arguments

    - by phasetwenty
    Is there a clean way to have your fabfile take command line arguments? I'm writing an installation script for a tool that I want to be able to specify an optional target directory via the command line. I wrote some code to test what would happen if I passed in some command line arguments: # fabfile.py import sys def install(): _get_options() def _get_options(): print repr(sys.argv[1:]) A couple of runs: $ fab install ['install'] Done. $ fab install --electric-boogaloo Usage: fab [options] <command>[:arg1,arg2=val2,host=foo,hosts='h1;h2',...] ... fab: error: no such option: --electric-boogaloo

  • Any thoughts on A/B testing in Django based project?

    - by Maddy
    We just now started doing the A/B testing for our Django based project. Can I get some information on best practices or useful insights about this A/B testing. Ideally each new testing page will be differentiated with a single parameter(just like Gmail). mysite.com/?ui=2 should give a different page. So for every view I need to write a decorator to load different templates based on the 'ui' parameter value. And I dont want to hard code any template names in decorators. So how would urls.py url pattern will be?

  • Django: Admin with multiple sites & languages

    - by lazerscience
    Hi everybody! I'm supposed to build some Django apps, that allow you to administer multiple sites through one backend. The contrib.sites framework is quite perfect for my purposes. I can run multiple instances of manage.py with different settings for each site; but how should django's admin deal with different settings for different sites, eg. if they have different sets of languages, a different (default) language? So there are some problem s to face if you have to work on objects coming from different sites in one admin... I think settings.ADMIN_FOR is supposed to be quite helpful for cases like this, but theres hardly any documentation about it and I think it's not really used in the actual Django version (?). So any ideas/solutions are welcome and much appreciated! Thanks a lot...

  • Parsing JSON file with Python -> google map api

    - by Hannes
    Hi all, I am trying to get started with JSON in Python, but it seems that I misunderstand something in the JSON concept. I followed the google api example, which works fine. But when I change the code to a lower level in the JSON response (as shown below, where I try to get access to the location), I get the following error message for code below: Traceback (most recent call last): File "geoCode.py", line 11, in test = json.dumps([s['location'] for s in jsonResponse['results']], indent=3) KeyError: 'location' How can I get access to lower information level in the JSON file in python? Do I have to go to a higher level and search the result string? That seems very weird to me? Here is the code I have tried to run: import urllib, json URL2 = "http://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=false" googleResponse = urllib.urlopen(URL2); jsonResponse = json.loads(googleResponse.read()) test = json.dumps([s['location'] for s in jsonResponse['results']], indent=3) print test Thank you for your responses.

  • Editting ForeignKey from "child" table

    - by profuel
    I'm programming on py with django. I have models: class Product(mymodels.Base): title = models.CharField() price = models.ForeignKey(Price) promoPrice = models.ForeignKey(Price, related_name="promo_price") class Price(mymodels.Base): value = models.DecimalField(max_digits=10, decimal_places=3) taxValue = models.DecimalField("Tax Value", max_digits=10, decimal_places=3) valueWithTax = models.DecimalField("Value with Tax", max_digits=10, decimal_places=3) I want to see INPUTs for both prices when editing product, but cannot find any possibility to do that. inlines = [...] works only from Price to Product, which is stupid in this case. Thanx for adnvance.

  • Include at text file as is in (Python) Sphinx Docs

    - by Gregg Lind
    (using Python-Sphinx Documentation tool) I have a .txt log file I'd like to build into _build/html unaltered. What do I need to alter in conf.py, index.rst, etc. Here is the layout: src/ index.rst some_doc.rst somefile.txt How do I get somefile.txt into the html build? I tried adding a line like this to index.rst: Contents: .. toctree:: :maxdepth: 2 some_doc "somefile.txt" hoping it would work by magic, but no magic here! Assuming this is even possible, what would I put in some_doc.rst to refer/link to that file? Note Yes, I'm aware I could put it in /static and just be done with it, but that seems like a total hack, and ugly.

  • How can I integrate a bitbucket repository with the hosted on-demand version of FogBugz?

    - by carrier
    I use the on-demand (hosted) version of FogBugz. I would like to start using Mercurial for source control. I would like to integrate FogBugz and a BitBucket repository. I gave it a bit of a try but things weren't going very well. FogBugz requires that you hook up your Mercurial client to a fogbugz.py python script. TortoiseHg doesn't seem to have the hgext directory that they refer to in instructions. So has anyone successfully done something similar?

  • How change Subversion's default binary mime-type?

    - by lamcro
    Subversion sets a binary file's svn:mime-type property to application/octet-stream by default. I need to change this default to some other mime-type. When I import for the first time this code, I would like Subversion to set mime-type to the one I choose. The reason is that my code base contains code in binary files (proprietary format), and I have the applications necessary to emulate diff and diff3 for these. But Subversion does not let me due to their default mime-type. Please note: There is no default extension (*.jar, *.py, etc) for these code files. Some files don't even have an extension. So configuring mime-type by file extension is not possible.

  • Prevent Django from redirecting to add trailing slash

    - by konrad
    UPDATED: Sorry, it looks like it's Apache that's rewriting it for some reason, not Django. I'll investigate further and post my findings. I need to add a /xmlrpc.php to my Byteflow installation to handle an application that is written for PHP blog engines and uses this hardcoded path. For some reason Byteflow appends a slash to this URL using a 301 Moved Permanently redirect, which breaks the application. It does not do so for the /robots.txt that is configured in a similar way. Relevant lines from the project urls.py: url(r'^xmlrpc.php$', 'django_xmlrpc.views.xmlrpc_handler'), url(r'^robots.txt$', include('robots.urls')), I read that the behavior was changed in the Django codebase in commit 6852 (in 2007) to prevent redirects being done for urls that have been explicitly configured not to contain any trailing slashes. I'm using Django 1.1. I assume that once I have fixed this problem, I should be able to use this application with Byteflow, because the application uses the MetaWeblog XML-RPC API. Any clue?

  • Printing to STDOUT and log file while removing ANSI color codes

    - by Arrieta
    I have the following functions for colorizing my screen messages: def error(string): return '\033[31;1m' + string + '\033[0m' def standout(string): return '\033[34;1m' + string + '\033[0m' I use them as follows: print error('There was a problem with the program') print "This is normal " + standout("and this stands out") I want to log the output to a file (in addition to STDOUT) WITHOUT the ANSI color codes, hopefully without having to add a second "logging" line to each print statement. The reason is that if you simply python program.py > out then the file out will have the ANSI color codes, which look terrible if you open in a plain text editor. Any advice?

  • Django how to handle # in variable name.

    - by Jack
    I've got a dictionary in python which is assigned as a template variable. One of the keys is named "#text" but when i try to access it using {{ artist.image.3."#text"}} I get an error which is File "/home/jack/Desktop/test/appengine/lib/django/django/template/__init__.py", line 558, in __init__ raise TemplateSyntaxError, "Could not parse the remainder: %s" % token[upto:] TemplateSyntaxError: Could not parse the remainder: "#text" So how can I use this in the template? I've tried putting quotes around it but to no avail. I'd like to not modify the dictionary if possible, but if its easy enough to do then I guess its okay. Thanks

  • Are any of these quad-tree libraries any good?

    - by Noctis Skytower
    It appears that a certain project of mine will require the use of quad-trees, something that I have never worked with before. From what I have read they should allow substantial performance enhancements than a brute-force attempt at the problem would yield. Are any of these python modules any good? Quadtree 0.1.2 <= No: unable to execute in Python 3.1 QuadTree <= Yes: simple while working with rectangles quadtree.py <= No: no support for needed operations EDIT: Does anyone know of a better implementation that the one presented on the pygame wiki article?

  • How to accept localized date format (e.g dd/mm/yy) in a DateField on an admin form ?

    - by tomjerry
    Is it possible to customize a django application to have accept localized date format (e.g dd/mm/yy) in a DateField on an admin form ? I have a model class : class MyModel(models.Model): date = models.DateField("Date") And associated admin class class MyModelAdmin(admin.ModelAdmin): pass On django administration interface, I would like to be able to input a date in following format : dd/mm/yyyy. However, the date field in the admin form expects yyyy-mm-dd. How can I customize things ? Nota bene : I have already specified my custom language code (fr-FR) in settings.py, but it seems to have no effect on this date input matter. Thanks in advance for your answer

  • Python sys.argv lists and indexes

    In the below code I understand that sys.argv uses lists, however I am not clear on how the index's are used here. def main(): if len(sys.argv) >= 2: name = sys.argv[1] else: name = 'World' print 'Hello', name if __name__ == '__main__': main() If I change name = sys.argv[1] to name = sys.argv[0] and type something for an argument it returns: Hello C:\Documents and Settings\fred\My Documents\Downloads\google-python-exercises \google-python-exercises\hello.py Which kind of make sense. Can someone explain how the 2 is used here: if len(sys.argv) >= 2: And how the 1 is used here: name = sys.argv[1]

  • How to auto-restart a python script on fail?

    - by norm
    This post describes how to keep a child process alive in a BASH script: http://stackoverflow.com/questions/696839/how-do-i-write-a-bash-script-to-restart-a-process-if-it-dies This worked great for calling another BASH script. However, I tried executing something similar where the child process is a Python script: #!/bin/bash PYTHON=/usr/bin/python2.6 function myprocess { $PYTHON daemon.py start } NOW=$(date +"%b-%d-%y") until myprocess; do echo "$NOW Prog crashed. Restarting..." >> error.txt sleep 1 done Now the behaviour is completely different. It seems the python script is no longer a child of of the bash script but seems to have 'taken over' the BASH scripts PID - so there is no longer a BASH wrapper round the called script...why?

  • MPI4Py Scatter sendbuf Argument Type?

    I'm having trouble with the Scatter function in the MPI4Py Python module. My assumption is that I should be able to pass it a single list for the sendbuffer. However, I'm getting a consistent error message when I do that, or indeed add the other two arguments, recvbuf and root: File "code/step3.py", line 682, in subbox_grid i = mpi_communicator.Scatter(station_range, station_data) File "Comm.pyx", line 427, in mpi4py.MPI.Comm.Scatter (src/ mpi4py_MPI.c:44993) File "message.pxi", line 321, in mpi4py.MPI._p_msg_cco.for_scatter (src/mpi4py_MPI.c:14497) File "message.pxi", line 232, in mpi4py.MPI._p_msg_cco.for_cco_send (src/mpi4py_MPI.c:13630) File "message.pxi", line 36, in mpi4py.MPI.message_simple (src/ mpi4py_MPI.c:11904) ValueError: message: expecting 2 or 3 items Here is the relevant code snipped, starting a few lines above 682 mentioned above. for station in stations #snip--do some stuff with station station_data = [] station_range = range(1,len(station)) mpi_communicator = MPI.COMM_WORLD i = mpi_communicator.Scatter(station_range, nsm) #snip--do some stuff with station[i] nsm = combine(avg, wt, dnew, nf1, nl1, wti[i], wtm, station[i].id) station_data = mpi_communicator.Gather(station_range, nsm) I've tried a number of combinations initializing station_range, but I must not be understanding the Scatter argument types properly.
