  • Complex form widgets in Django

    - by Shekhar
    I am looking for good helper libraries to generate a rather complex form in Django. Dynamic field dependencies: Say if option a is selected certain fields are shown/hidden and subset of these are mandatory depending on option selection. Add more: On clicking "Add more" button that clones some widget. This is something which ToscaWidgets is capable of handle. http://toscawidgets.org/documentation/tw.dynforms/tutorial.html#growing Currently I am managing this with some jquery code however not completely satisfied. TIA

  • How can I use geoalchemy with elixir autoload tables?

    - by Dan Ellis
    I'm using geoalchemy and autoloaded tables, but I'd like to use Elixir, because it has a nicer query syntax. Does anyone know how to get them to work together? I did get it working with this code -- http://pastie.textmate.org/private/y3biyvosuejkrtxbpdv1a -- but that still gives the ugly warning about not recognising the geometry column when the table is reflected. Ideally, what I'd like to do is to get SQLAlchemy's own table reflection to recognise the geometry columns. How would I plumb them together?

  • Crossfading audio with PyQT4 and Phonon

    - by dwelch
    I'm trying to get audio files to crossfade with phonon. I'm using PyQT4. I have tracks queuing properly, but I'm stuck with the fade effect. I think I need to be using the KVolumeFader effect. Here's my current code: def music_play(self): self.delayedInit() self.m_media.setCurrentSource(Phonon.MediaSource(self.playlist[self.playlist_pos])) self.m_media.play() def music_stop(self): self.m_media.stop() def delayedInit(self): if not self.m_media: self.m_media = Phonon.MediaObject(self) audioOutput = Phonon.AudioOutput(Phonon.MusicCategory, self) Phonon.createPath(self.m_media, audioOutput) def enqueueNextSource(self): if len(self.playlist) >= self.playlist_pos+1: self.playlist_pos += 1 self.m_media.enqueue(Phonon.MediaSource(self.playlist[self.playlist_pos])) else: self.m_media.stop() Can anyone give me some advice on implementing the effect?

  • JSON Serialization of a Django inherited model

    - by Simon Morris
    Hello, I have the following Django models class ConfigurationItem(models.Model): path = models.CharField('Path', max_length=1024) name = models.CharField('Name', max_length=1024, blank=True) description = models.CharField('Description', max_length=1024, blank=True) active = models.BooleanField('Active', default=True) is_leaf = models.BooleanField('Is a Leaf item', default=True) class Location(ConfigurationItem): address = models.CharField(max_length=1024, blank=True) phoneNumber = models.CharField(max_length=255, blank=True) url = models.URLField(blank=True) read_acl = models.ManyToManyField(Group, default=None) write_acl = models.ManyToManyField(Group, default=None) alert_group= models.EmailField(blank=True) The full model file is here if it helps. You can see that Company is a child class of ConfigurationItem. I'm trying to use JSON serialization using either the django.core.serializers.serializer or the WadofStuff serializer. Both serializers give me the same problem... >>> from cmdb.models import * >>> from django.core import serializers >>> serializers.serialize('json', [ ConfigurationItem.objects.get(id=7)]) '[{"pk": 7, "model": "cmdb.configurationitem", "fields": {"is_leaf": true, "extension_attribute_10": "", "name": "", "date_modified": "2010-05-19 14:42:53", "extension_attribute_11": false, "extension_attribute_5": "", "extension_attribute_2": "", "extension_attribute_3": "", "extension_attribute_1": "", "extension_attribute_6": "", "extension_attribute_7": "", "extension_attribute_4": "", "date_created": "2010-05-19 14:42:53", "active": true, "path": "/Locations/London", "extension_attribute_8": "", "extension_attribute_9": "", "description": ""}}]' >>> serializers.serialize('json', [ Location.objects.get(id=7)]) '[{"pk": 7, "model": "cmdb.location", "fields": {"write_acl": [], "url": "", "phoneNumber": "", "address": "", "read_acl": [], "alert_group": ""}}]' >>> The problem is that serializing the Company model only gives me the fields directly associated with that model, not the fields from it's parent object. Is there a way of altering this behaviour or should I be looking at building a dictionary of objects and using simplejson to format the output? Thanks in advance ~sm

  • metaclass multiple inheritance inconsistency

  • Django doctests in views.py

    - by Brian M. Hunt
    The Django documentation on tests states: For a given Django application, the test runner looks for doctests in two places: The models.py file. You can define module-level doctests and/or a doctest for individual models. It's common practice to put application-level doctests in the module docstring and model-level doctests in the model docstrings. A file called tests.py in the application directory -- i.e., the directory that holds models.py. This file is a hook for any and all doctests you want to write that aren't necessarily related to models. Out of curiosity I'd like to know why Django's testrunner is limited to the doctests in models.py, but more practically I'd like to know how one could expand the testrunner's doctests to include (for example) views.py and other modules when running manage.py test. I'd be grateful for any input. Thank you. Brian

  • Function to hide sloppy phone numbers..

    - by Frank Malina
    I need to hide phone numbers (and maybe other contact details) in user generated content to protect my users from anonymous web. Input is very random, therefore I'd be looking to replace anything that looks like a phone number (e.g.: string of 3 or more numbers) with just dots, and also perhaps remove some exotic notations of e-mail addresses. What is the best way to do this? Nice and slick, reusable. Give away your secret regexes. Write in any language. Except perhaps COBOL :) function privacy($str){ // protect phone numbers // protect e-mail addresses // protect web addresses }

  • How to sort my paws?

    - by Ivo Flipse
    In my previous question I got an excellent answer that helped me detect where a paw hit a pressure plate, but now I'm struggling to link these results to their corresponding paws: I manually annotated the paws (RF=right front, RH= right hind, LF=left front, LH=left hind). As you can see there's clearly a pattern repeating pattern and it comes back in aknist every measurement. Here's a link to a presentation of 6 trials that were manually annotated. My initial thought was to use heuristics to do the sorting, like: There's a ~60-40% ratio in weight bearing between the front and hind paws; The hind paws are generally smaller in surface; The paws are (often) spatially divided in left and right. However, I’m a bit skeptical about my heuristics, as they would fail on me as soon as I encounter a variation I hadn’t thought off. They also won’t be able to cope with measurements from lame dogs, whom probably have rules of their own. Furthermore, the annotation suggested by Joe sometimes get's messed up and doesn't take into account what the paw actually looks like. Based on the answers I received on my question about peak detection within the paw, I’m hoping there are more advanced solutions to sort the paws. Especially because the pressure distribution and the progression thereof are different for each separate paw, almost like a fingerprint. I hope there's a method that can use this to cluster my paws, rather than just sorting them in order of occurrence. So I'm looking for a better way to sort the results with their corresponding paw. For anyone up to the challenge, I have pickled a dictionary with all the sliced arrays that contain the pressure data of each paw (bundled by measurement) and the slice that describes their location (location on the plate and in time). To clarfiy: walk_sliced_data is a dictionary that contains ['ser_3', 'ser_2', 'sel_1', 'sel_2', 'ser_1', 'sel_3'], which are the names of the measurements. Each measurement contains another dictionary, [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10] (example from 'sel_1') which represent the impacts that were extracted. Also note that 'false' impacts, such as where the paw is partially measured (in space or time) can be ignored. They are only useful because they can help recognizing a pattern, but won't be analyzed. And for anyone interested, I’m keeping a blog with all the updates regarding the project!

  • A good matplot tutorial (from beginner to intermidiate)?

    - by morpheous
    Can anyone recommend a good matplot tutorial. I am a complete beginner - but have used similar software (matlab, R etc), in my halcyon days at University (i.e. a long time ago). A google search brings up a list of dubious quality, and the 'official' docs are too terse, or provide examples that are more 'edge case' (e.g. drawing dolphins swimming in a bubble), than one is likely to meet in practise. I want a manual that provides the following information in a well structured manner: Introduction to the data types Introduction to 2D plotting with some simple practical examples (simple 2D graphs) Introduction to 3D plotting with some simple practical examples (simple 2D graphs: contour and surface)

  • Unit testing with django-celery?

    - by Jason Webb
    I am trying to come up with a testing methodology for our django-celery project. I have read the notes in the documentation, but it didn't give me a good idea of what to actually do. I am not worried about testing the tasks in the actual daemons, just the functionality of my code. Mainly I am wondering: How can we bypass task.delay() during the test (I tried setting CELERY_ALWAYS_EAGER = True but it made no difference)? How do we use the test settings that are recommended (if that is the best way) without actually changing our settings.py? Can we still use manage.py test or do we have to use a custom runner? Overall any hints or tips for testing with celery would be very helpful.

  • Check if the integer in a list is not duplicated, and sequential

    - by prosseek
    testGroupList is a list of integer. I need to check the numbers in testGroupList is sequential (i.e, 1-2-3-4...) and not duplicate numbers. Ignore the negative integer. I implemented it as follows, and it's pretty ugly. Is there any clever way to do this? buff = filter(lambda x: x 0, testGroupList) maxval = max(buff) for i in range(maxval): id = i+1 val = buff.count(id) if val == 1: print id, elif val = 2: print "(Test Group %d duplicated %d times)" % (id, val), elif val == 0: print "(Test Group %d missing)" % id,

  • Regex to ensure group match doesn't end with a specific character

    - by AJ
    I'm having trouble coming up with a regular expression to match a particular case. I have a list of tv shows in about 4 formats: Name.Of.Show.S01E01 Name.Of.Show.0101 Name.Of.Show.01x01 Name.Of.Show.101 What I want to match is the show name. My main problem is that my regex matches the name of the show with a preceding '.'. My regex is the following: "^([0-9a-zA-Z\.]+)(S[0-9]{2}E[0-9]{2}|[0-9]{4}|[0-9]{2}x[0-9]{2}|[0-9]{3})" Some Examples: >>> import re >>> SHOW_INFO = re.compile("^([0-9a-zA-Z\.]+)(S[0-9]{2}E[0-9]{2}|[0-9]{4}|[0-9]{2}x[0-9]{2}|[0-9]{3})") >>> match = SHOW_INFO.match("Name.Of.Show.S01E01") >>> match.groups() ('Name.Of.Show.', 'S01E01') >>> match = SHOW_INFO.match("Name.Of.Show.0101") >>> match.groups() ('Name.Of.Show.0', '101') >>> match = SHOW_INFO.match("Name.Of.Show.01x01") >>> match.groups() ('Name.Of.Show.', '01x01') >>> match = SHOW_INFO.match("Name.Of.Show.101") >>> match.groups() ('Name.Of.Show.', '101') So the question is how do I avoid the first group ending with a period? I realize I could simply do: var.strip(".") However, that doesn't handle the case of "Name.Of.Show.0101". Is there a way I could improve the regex to handle that case better? Thanks in advance.

  • Eventlet and locking

    Since Eventlet uses green threading and asynchronous I/O, do I still need to set locks before accessing objects? My understanding is that greenlets are all part of one thread and locking isn't necessary. Can anyone confirm or deny this?
