  • Python Fabric error

    - by jwesonga
    I'm running fabric (Django deployment to apache) and everything seems to work fine until I get to the task for installing the site: def install_site(): "Add the virtualhost file to apache" require('release', provided_by=[deploy, setup]) sudo('cd %(path)/releases/%(release)/%(release); cp %(project_name)/%(virtualhost_path)/%(project_domain) /etc/apache2/sites-available/%(project_domain)s') sudo('cd /etc/apache2/sites-available; a2ensite %(project_domain)') I keep getting this error: [173.203.124.16] sudo: cd %(path)/releases/%(release)/%(release); [173.203.124.16] err: /bin/bash: -c: line 0: syntax error near unexpected token `(' [173.203.124.16] err: /bin/bash: -c: line 0: `cd %(path)/releases/%(release)/%(r elease);' Warning: sudo() encountered an error (return code 2) while executing 'cd %(path) /releases/%(release)/%(release);' I've gone through the fabfile.py over and over and I can't see why the error is coming...any ideas?

  • Django-pyodbc SQL Server/freetds server connection problems on linux

    - by wizard
    Error: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified (0) (SQLDriverConnectW)') I'm migrating from developing on a windows development machine to Linux machine in production and I'm having issues with the freetds driver. As far as I can tell that error message means it can't find the driver. I can connect via the cli via sqsh and tsql. I've setup my settings.py as such. 'bc2db': { 'ENGINE': 'sql_server.pyodbc', 'NAME': 'DataTEST', 'USER': 'appuser', 'PASSWORD': 'PASS', 'HOST': 'bc2.domain.com', 'options': { 'driver': 'FreeTDS', } }, Does anyone have any SQL Server experience with django? do I have to use a dns? (how would I format that?)

  • Google Appengine and Python exceptions

    - by Jim
    In my Google Appengine application I have defined a custom exception InvalidUrlException(Exception) in the module 'gvu'. Somewhere in my code I do: try: results = gvu.article_parser.parse(source_url) except gvu.InvalidUrlException as e: self.redirect('/home?message='+str(e)) ... which works fine in the local GAE development server, but raises <type 'exceptions.SyntaxError'>: invalid syntax (translator.py, line 18) when I upload it. (line 18 is the line starting with 'except') The problem seems to come from the 'as e' part: if I remove it I don't get this exception anymore. However I would like to be able to access the raised exception. Have you ever encountered this issue? Is there an alternative syntax?

  • Webdriver python bindings

    - by Ockonal
    Hello, I can't make python bindings for webdriver workable. Here is tutorial for installing. easy_install webdriver Won't find webdriver package so I have to install it manually from sources. I've downloaded source from trunk, set WEBDRIVER and PYTHONPATH variables and installed webdriver: ~$ cd ~ ~$ svn checkout http://selenium.googlecode.com/svn/trunk/ selenium-read-only ~$ cd selenium-read-only ~# python setup.py install ~$ env |grep PYT ~$> PYTHONPATH=:/home/ockonal/selenium-read-only/../../../firefox/lib-src:/home/ockonal/selenium-read-only/.. ~$ env |grep WEB ~$> WEBDRIVER=/home/ockonal/selenium-read-only Then I downloaded RemoteDriverServer.jar and ran it: java -jar RemoteDriverServer.jar 8888 Now I want to include webdriver module in python script: from selenium.firefox.webdriver import WebDriver ImportError: No module named firefox.webdriver

  • Python class design - Splitting up big classes into multiple ones to group functionality

    - by Ivo Wetzel
    OK I've got 2 really big classes 1k lines each that I currently have split up into multiple ones. They then get recombined using multiple inheritance. Now I'm wondering, if there is any cleaner/better more pythonic way of doing this. Completely factoring them out would result in endless amounts of self.otherself.do_something calls, which I don't think is the way it should be done. To make things clear here's what it currently looks like: from gui_events import GUIEvents # event handlers from gui_helpers import GUIHelpers # helper methods that don't directly modify the GUI # GUI.py class GUI(gtk.Window, GUIEvents, GUIHelpers): # general stuff here stuff here One problem that is result of this is Pylint complaining giving me trillions of "init not called" / "undefined attribute" / "attribute accessed before definition" warnings.

  • undefined symbol: PyUnicodeUCS2_Decode whilst trying to install psycopg2

    - by Marco Fucci
    I'm getting an error whilst trying to install psycopg2 on ubuntu 9.10 64 bit. The error is: >>> import psycopg2 Traceback (most recent call last): File "<stdin>", line 1, in <module> File "psycopg2/__init__.py", line 69, in <module> from _psycopg import BINARY, NUMBER, STRING, DATETIME, ROWID ImportError: psycopg2/_psycopg.so: undefined symbol: PyUnicodeUCS2_Decode I've tried downloading the package from http://initd.org/pub/software/psycopg/ and installing it. I've tried by using easy_install too. No error during the installation. It's quite weird as my python (2.6.2) has been compiled with UCS4 and so the installation should just work without problems. Any help would be appreciated. Cheers

  • OpenCV 2.0 and Python

    - by Jive Dadson
    I cannot get the example Python programs to run. When executing the Python command "from opencv import cv" I get the message "ImportError: No module named _cv". There is a stale _cv.pyd in the site-packages directory, but no _cv.py anywhere. See step 5 below. MS Windows XP, VC++ 2008, Python 2.6, OpenCV 2.0 Here's what I have done. Downloaded and ran the MS Windows installer for OpenCV2.0. Downloaded and installed CMake Downloaded and installed SWIG Ran CMake. After unchecking "ENABLE_OPENMP" in the CMake GUI, I was able to build OpenCV using INSTALL.vcproj and BUILD_ALL.vcproj. I do not know what the difference is, so I built everything under both of those project files. The C example programs run fine. Copied contents of OpenCV2.0/Python2.6/lib/site-packages to my installed Python2.6/lib/site-packages directory. I notice that it contains an old _cv.pyd and an old libcv.dll.a.

  • Log axis2 client requests and responses

    - by Manuel Darveau
    I would like to log all requests/responses made by an axis2 client. I tried to create a file called client-config.wsdd as describer in http://code.google.com/support/bin/answer.py?hl=en&answer=15137 but without success (I don't get a log file). Requests are made over https and I am not sure if it matters. I tried <transport name="http" pivot="java:org.apache.axis.transport.http.HTTPSender"/> and <transport name="https" pivot="java:org.apache.axis.transport.http.HTTPSender"/> without success.

  • Apps not showing in Django admin site

    - by jack
    I have a Django project with about 10 apps in it. But the admin interface only shows Auth and Site models which are part of Django distribution. Yes, the admin interface is up and working but none of my self-written apps shows there. INSTALLED_APPS INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.sites', 'django.contrib.contenttypes', 'django.contrib.humanize', 'django.contrib.sessions', 'django.contrib.admin', 'django.contrib.admindocs', 'project.app1', ... app1/admin.py from django.contrib import admin from project.app1.models import * admin.site.register(model1) admin.site.register(model2) admin.site.register(model3) What could be wrong in this case? Looks like everything is configured as what document says. Thank you in advance.

  • Django: reverse lookup URL of feeds?

    - by Santa
    I am having trouble doing a reverse URL lookup for Django-generated feeds. I have the following setup in urls.py: feeds = { 'latest': LatestEntries, } urlpatterns = patterns('', # ... # enable feeds (RSS) url(r'^feeds/(?P<url>.*)/$', 'django.contrib.syndication.views.feed', {'feed_dict': feeds}, name='feeds_view'), ) I have tried using the following template tag: <a href="{% url feeds_view latest %}">RSS feeds</a> But the resulting link is not what want (http://my.domain.com/feeds//). It should be http://my.domain.com/feeds/latest/. For now, I am using a hack to generate the URL for the template: <a href="http://{{ request.META.HTTP_HOST }}/feeds/latest">RSS feeds</a> But, as you can see, it clearly is not DRY. Is there something I am missing?

  • SyntaxError using gdata-python-client to access Google Book Search Data API

I'm not sure how to interpret the error message. If it matters, I'm using python 2.6.5.

  • Loading fixtures in django unit tests

    - by loder
    I'm trying to start writing unit tests for django and I'm having some questions about fixtures: I made a fixture of my whole project db (not certain application) and I want to load it for each test, because it looks like loading only the fixture for certain app won't be enough. I'd like to have the fixture stored in /proj_folder/fixtures/proj_fixture.json. I've set the FIXTURE_DIRS = ('/fixtures/',) in my settings.py. Then in my testcase I'm trying fixtures = ['proj_fixture.json'] but my fixtures don't load. How can this be solved? How to add the place for searching fixtures? In general, is it ok to load the fixture for the whole test_db for each test in each app (if it's quite small)? Thanks!

  • What's a good Minimal Server-Side Javascript Framework?

    - by Nick Retallack
    So I was writing a web app with web.py that uses plenty of client-side javascript, and my database is on couchdb so the queries are in javascript too, and eventually I just got to thinking, why not skip the python and go all javascript? Besides, some functions need to run once on the client and again on the server to make sure you're not spoofing, so why translate between javascript and python? So I'm looking for a simple lightweight javascript web framework. All I really need is the url routing, request and response stuff (standard wsgi?), and a way to hook into a big http server like nginx. What do you guys recommend?

  • Rewriting An URL With Regular Expression Substitution in Routes

    - by Sean M
    In my Pylons app, some content is located at URLs that look like http://mysite/data/31415. Users can go to that URL directly, or search for "31415" via the search page. My constraints, however, mean that http://mysite/data/000031415 should go to the same page as the above, as should searches for "0000000000031415." Can I strip leading zeroes from that string in Routes itself, or do I need to do that substitution in the controller file? If it's possible to do it in routing.py, I'd rather do it there - but I can't quite figure it out from the documentation that I'm reading.

  • Having py2exe include my data files (like include_package_data)

    - by cool-RR
    I have a Python app which includes non-Python data files in some of its subpackages. I've been using the include_package_data option in my setup.py to include all these files automatically when making distributions. It works well. Now I'm starting to use py2exe. I expected it to see that I have include_package_data=True and to include all the files. But it doesn't. It puts only my Python files in the library.zip, so my app doesn't work. How do I make py2exe include my data files?

  • Web publishing system with code highlighting

    - by Dragos Toader
    I'd like to publish some of the many programs I've written on the web. Is there a syntax highlighting Linux web publishing application (CMS/Blog/RoR app) that displays syntax for C++, Python, Bash scripts, SQL, VBA, awk, Erlang, java, makefiles, Ruby, Pascal and other languages? The more syntax settings configuration files, the better. The extensions I have in Textpad (for which I have syntax highlighting -- syn files) are .as, .asm, .asp, .awk, .bas, .bat, .c, .conf, .cpp, .cs, .ctl, .dfm, .dsc, .erl, .fnc, .h, .hpp, .inf, .ini, .jav, .java, .mak, .nsh, .nsi, .ora, .pas, .pkb, .pks, .pl, .prc, .py, .reg, .rsp, .sh, .sql, .syn, .tcl, .trg, .vw, .xml, .xsl, .xslfo

  • Django ImageField validation & PIL

    - by Zayatzz
    Hello On sunday, I had problems with python modules, when I installed stackless python. Now I have compiled and installed : setuptools & python-mysqldb and i got my django project up and running again. (i also reinstalled django-1.1), Then I compiled and installed, jpeg, freetype2 and PIL. I also started using mod_wsgi instead of mod_python. But when uploading imagefield in form I get validationerror: Upload a valid image. The file you uploaded was either not an image or a corrupted image. Searchmonkey shows that it comes from field.py imagefield validation. before raising this error it imports Image from PIL, opens file and verfies it. I tried importing PIL from python prompt manually - it worked just fine. Same with Image.open and Image.verify. So what could be causing this problem? Alan

  • jquery-Ajax call on tornado handlers waits for pervious ajax call to return

    - by harshh
    Hey All. I recently started testing TornadoWeb for a home-project, which uses jquery getJSON function to call my tornado handlers. And found something strange, which i seek an explanation for. I fire an ajax request for Handler1 on tornado, and in some cases request for Handler2 is initiated before Handler1 returns. It appears from development-server logs, and firebug console-debugging, that Handler2 request waits for Handler1 request to finish, and then return. So basically, XHR call is waiting for earlier XHRs. They are supposed to be asynchronous/non-blocking right?? Or am i missing something. You can check the test-case environment called testtornado at http://github.com/harshh/Harsh-Projects/ with main.py as server triggering file. I would appreciate help from anyone who can throw some light on this.

  • need help figuring out dynamic menu generation in django

    - by photographer
    I need to dynamically generate a code like this in the resulting html: <p>>> gallery one</p> <p><a href="../gallery2">gallery two</a></p> <p><a href="../about">about the author</a></p> <p><a href="../news">our news</a></p> I do have menu_code string variable created in views.py (it is generated depending on an item number of the current page passed — 1 in the case above), which contains that long string with the code shown above. It is (well, supposed to) passed by locals() into the html template (all other variables are passed that way successfully): return render_to_response('gallery_page.html', locals()) I have this: {% include menu_code %} inside the template html. But instead of being interpreted as code it is just shown as text in the browser. What am I doing wrong? How to make it work as a dynamically generated menu?
