  • global applied stylesheet link on debian box

    - by James
    Hi there, Having some trouble identifying what is wrong with my link to an external CSS stylesheet... I am using a debian box to host some things... including a file i am accessing page.py which is located in /var/www/cgi-bin. I need this page to link to a css file which currently has the pathname /var/www/styles.css. Now I know I could link as: <link rel="stylesheet" href="**../styles.css**" type="text/css"> and the problem is solved but I would rather have a 'global' link, that I can use in other py files elsewhere in my filesystem and they will all point to /var/www/styles.css The information I have searched suggests that <link rel="stylesheet" href="**/var/www/styles.css**" type="text/css"> should work fine... but it doesn't. I have tried multiple combinations of everything I know but it doesn't seem to link as I would expect. Can anyone point me in the right direction?

  • Django: How to write the reverse function for the following

    - by ninja123
    The urlconf and view is as follows: url(r'^register/$', register, { 'backend': 'registration.backends.default.DefaultBackend' }, name='registration_register'), def register(request, backend, success_url=None, form_class=None, disallowed_url='registration_disallowed', template_name='registration/registration_form.html', extra_context=None): What i want to do is redirect users to the register page and specify a success_url. I tried reverse('registration.views.register', kwargs={'success_url':'/test/' }) but that doesn't seem to work. I've been trying for hours and can't get my mind around getting it right. Thanks

  • read the dictionary value from array

    - by ben martin
    CALORIES = \ { 'Beef' : 200, \ 'Chicken' : 140, \ } class Food(): __slots__ = ( 'cal' # Calories ) def mkFood( name ): """Create and return a newly initialized Food item""" result = Food() result.cal = calorie in dict(CALORIES[1]) return result Is that a proper way to the value of the target item in Calories? Like getting 200, 140, such like that. result.cal = calorie in dict(CALORIES[1])

  • Problems installing a package from PyPI: root files not installed

    - by intuited
    After installing the BitTorrent-bencode package, either via easy_install BitTorrent-bencode or pip install BitTorrent-bencode, or by downloading the tarball and installing that via easy_install $tarball, I discover that /usr/local/lib/python2.6/dist-packages/BitTorrent_bencode-5.0.8-py2.6.egg/ contains EGG-INFO/ and test/ directories. Although both of these subdirectories contain files, there are no files in the BitTorr* directory itself. The tarball does contain bencode.py, which is meant to be the actual source for this package, but it's not installed by either of those utils. I'm pretty new to all of this so I'm not sure if this is a problem with the package or with what I'm doing. The package was packaged a while ago (2007), so perhaps it's using some deprecated configuration aspect that I need to supply a command-line flag for. I'm more interested in learning what's wrong with either the package or my procedures than in getting this particular package installed; there is another package called hunnyb that seems to do a decent enough job of decoding bencoded data. Mostly I'd like to know how to deal with such problems in other packages.

  • Indexing one-dimensional numpy.array as matrix

    - by Alain
    I am trying to index a numpy.array with varying dimensions during runtime. To retrieve e.g. the first row of a n*m array a, you can simply do a[0,:] However, in case a happens to be a 1xn vector, this code above returns an index error: IndexError: too many indices As the code needs to be executed as efficiently as possible I don't want to introduce an if statement. Does anybody have a convenient solution that ideally doesn't involve changing any data structure types?

  • "UserWarning: Unbuilt egg for setuptools" - What does this actually mean?

    - by Wolo
    Hiya. When I install things into a virtualenv using pip I often see the message "UserWarning: Unbuilt egg for setuptools". I always safely ignore it and go about my business and it doesn't seem to cause me any problems. But I've suddenly been smacked in the face with curiosity, and wondered if someone could explain what it means, exactly? Also, does the new virtualenv option to use distribute instead fit into all this somewhere? Should I be using that instead, or just ignoring it until distutils2 comes out? (apologies if that's totally unrelated - maybe it should be a new question?) Thanks!

  • File mode for creating+reading+appending+binary

    - by MihaiD
    I need to open a file for reading and writing. If the file is not found, it should be created. It should also be treated as a binary for Windows. Can you tell me the file mode sequence I need to use for this? I tried 'r+ab' but that doesn't create the files if they are not found. Thanks

  • How do I make a defaultdict safe for unexpecting clients?

    - by ~miki4242
    Several times (even several in a row) I've been bitten by the defaultdict bug. d = defaultdict(list) ... try: v = d["key"] except KeyError: print "Sorry, no dice!" For those who have been bitten too, the problem is evident: when d has no key 'key', the v = d["key"] magically creates an empty list and assigns it to both d["key"] and v instead of raising an exception. Which can be quite a pain to track down if d comes from some module whose details one doesn't remember very well. I'm looking for a way to take the sting out of this bug. For me, the best solution would be to somehow disable a defaultdict's magic before returning it to the client.

  • Gtk: How can I get a part of a file in a textview with scrollbars relating to the full file

    - by badgerman1
    I'm trying to make a very large file editor (where the editor only stores a part of the buffer in memory at a time), but I'm stuck while building my textview object. Basically- I know that I have to be able to update the text view buffer dynamically, and I don't know hot to get the scrollbars to relate to the full file while the textview contains only a small buffer of the file. I've played with Gtk.Adjustment on a Gtk.ScrolledWindow and ScrollBars, but though I can extend the range of the scrollbars, they still apply to the range of the buffer and not the filesize (which I try to set via Gtk.Adjustment parameters) when I load into textview. I need to have a widget that "knows" that it is looking at a part of a file, and can load/unload buffers as necessary to view different parts of the file. So far, I believe I'll respond to the "change_view" to calculate when I'm off, or about to be off the current buffer and need to load the next, but I don't know how to get the scrollbars to have the top relate to the beginning of the file, and the bottom relate to the end of the file, rather than to the loaded buffer in textview. Any help would be greatly appreciated, thanks!

  • PHP's form bracket trick is to Django's ___?

    - by Matt
    In PHP you can create form elements with names like: category[1] category[2] or even category[junk] category[test] When the form is posted, category is automatically turned into a nice dictionary like: category[1] => "the input value", category[2] => "the other input value" Is there a way to do that in Django? request.POST.getlist isn't quite right, because it simply returns a list, not a dictionary. I need the keys too.

  • Amazon S3 permissions

    - by Joe
    Trying to understand S3...How do you limit access to a file you upload to S3? For example, from a web application, each user has files they can upload, but how do you limit access so only that user has access to that file? It seems like the query string authentication requires an expiration date and that won't work for me, is there another way to do this?

  • testing existing attribute of a @classmethod function, yields AttributeError

    - by alex
    i have a function which is a class method, and i want to test a attribute of the class which may or may not be None, but will exist always. class classA(): def __init__(self, var1, var2 = None): self.attribute1 = var1 self.attribute2 = var2 @classmethod def func(self,x): if self.attribute2 is None: do something i get the error AttributeError: class classA has no attribute 'attributeB' when i access the attribute like i showed but if on command line i can see it works, x = classA() x.attributeB is None True so the test works. if i remove the @classmethod decorator from func, the problem disapears. if i leave the @classmethod decorator, it only seems to affect variables which are supplied default values in the super-class's constructor. whats going on in the above code?

  • Why does 'url' not work as a variable here?

    - by kryptobs2000
    I originally had the variable cpanel named url and the code would not return anything. Any idea why? It doesn't seem to be used by anything else, but there's gotta be something I'm overlooking. import urllib2 cpanel = 'http://www.tas-tech.com/cpanel' req = urllib2.Request(cpanel) try: handle = urllib2.urlopen(req) except IOError, e: if hasattr(e, 'code'): if e.code != 401: print 'We got another error' print e.code else: print e.headers print e.headers['www-authenticate']
