• Passing in **kwargs from Flex over PyAMF

  - by cookiecaper

  Anyone know if it is easily possible to send **kwargs over PyAMF from NetConnection.call()? I would like it. I could write a wrapper around the actual function and expose that and perform some parsing manually to determine the kwargs to pass in, but I don't want to do that. I will just use a normal argument list in that case.

• Setting attributes of a class during construction from **kwargs

  - by Carson Myers

  Python noob here, Currently I'm working with SQLAlchemy, and I have this: from __init__ import Base from sqlalchemy.schema import Column, ForeignKey from sqlalchemy.types import Integer, String from sqlalchemy.orm import relationship class User(Base): __tablename__ = "users" id = Column(Integer, primary_key=True) username = Column(String, unique=True) email = Column(String) password = Column(String) salt = Column(String) openids = relationship("OpenID", backref="users") User.__table__.create(checkfirst=True) #snip definition of OpenID class def create(**kwargs): user = User() if "username" in kwargs.keys(): user.username = kwargs['username'] if "email" in kwargs.keys(): user.username = kwargs['email'] if "password" in kwargs.keys(): user.password = kwargs['password'] return user This is in /db/users.py, so it would be used like: from db import users new_user = users.create(username="Carson", password="1234") new_user.email = "[email protected]" users.add(new_user) #this function obviously not defined yet but the code in create() is a little stupid, and I'm wondering if there's a better way to do it that doesn't require an if ladder, and that will fail if any keys are added that aren't in the User object already. Like: for attribute in kwargs.keys(): if attribute in User: user.__attribute__[attribute] = kwargs[attribute] else: raise Exception("blah") that way I could put this in its own function (unless one hopefully already exists?) So I wouldn't have to do the if ladder again and again, and so I could change the table structure without modifying this code. Any suggestions?

• Django exclude(**kwargs) help

  - by shawnjan

  Hey guys/gals! I had a question for you, something that I can't seem to find the solution for... Basically, I have a model called Environment, and I am passing all of them to a view, and there are particular environments that I would like to exclude. Now, I know there is a exclude function on a queryset, but I can't seem to figure out how to use it for multiple options... For example, I tried this but it didn't work: kwargs = {"name": "env1", "name": "env2"} envs = Environment.objects.exclude( kwards ) But the only thing that it will exclude is the last "name" value in the list of kwargs. I understand why it does that now, but I still can't seem to exclude multiple objects with one command. Any help is much appreciated! Shawn

• Copy **kwargs to self?

  - by Mark

  Given class ValidationRule: def __init__(self, **kwargs): # code here Is there a way that I can define __init__ such that if I were to initialize the class with something like ValidationRule(other='email') then self.other would be "added" to class without having to explicitly name every possible kwarg?

• 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

• Python New-style Classes and the Super Function

  - by sfjedi

  This is not the result I expect to see: class A(dict): def __init__(self, *args, **kwargs): self['args'] = args self['kwargs'] = kwargs class B(A): def __init__(self, *args, **kwargs): super(B, self).__init__(args, kwargs) print 'Instance A:', A('monkey', banana=True) #Instance A: {'args': ('monkey',), 'kwargs': {'banana': True}} print 'Instance B:', B('monkey', banana=True) #Instance B: {'args': (('monkey',), {'banana': True}), 'kwargs': {}} I'm just trying to get classes A and B to have consistent values set. I'm not sure why the kwargs are being inserted into the args, but I'm to presume I am either calling init() wrong from the subclass or I'm trying to do something that you just can't do. Any tips?

• python list mysteriously getting set to something within my django/piston handler

  - by Anverc

  To start, I'm very new to python, let alone Django and Piston. Anyway, I've created a new BaseHandler class "class BaseApiHandler(BaseHandler)" so that I can extend some of the stff that BaseHandler does. This has been working fine until I added a new filter that could limit results to the first or last result. Now I can refresh the api page over and over and sometimes it will limit the result even if I don't include /limit/whatever in my URL... I've added some debug info into my return value to see what is happening, and that's when it gets more weird. this return value will make more sense after you see the code, but here they are for reference: When the results are correct: "statusmsg": "2 hours_detail found with query: {'empid':'22','datestamp':'2009-03-02',}", when the results are incorrect (once you read the code you'll notice two things wrong. First, it doesn't have 'limit':'None', secondly it shouldn't even get this far to begin with. "statusmsg": "1 hours_detail found with query: {'empid':'22','datestamp':'2009-03-02',with limit[0,1](limit,None),}", It may be important to note that I'm the only person with access to the server running this right now, so even if it was a cache issue, it doesn't make sense that I can just refresh and get different results by hitting F5 while viewing: http://localhost/api/hours_detail/datestamp/2009-03-02/empid/22 Here's the code broken into urls.py and handlers.py so that you can see what i'm doing: URLS.PY urlpatterns = patterns('', #hours_detail/id/{id}/empid/{empid}/projid/{projid}/datestamp/{datestamp}/daterange/{fromdate}to{todate}/limit/{first|last}/exact #empid is required # id, empid, projid, datestamp, daterange can be in any order url(r'^api/hours_detail/(?:' + \ r'(?:[/]?id/(?P<id>\d+))?' + \ r'(?:[/]?empid/(?P<empid>\d+))?' + \ r'(?:[/]?projid/(?P<projid>\d+))?' + \ r'(?:[/]?datestamp/(?P<datestamp>\d{4,}[-/\.]\d{2,}[-/\.]\d{2,}))?' + \ r'(?:[/]?daterange/(?P<daterange>(?:\d{4,}[-/\.]\d{2,}[-/\.]\d{2,})(?:to|/-)(?:\d{4,}[-/\.]\d{2,}[-/\.]\d{2,})))?' + \ r')+' + \ r'(?:/limit/(?P<limit>(?:first|last)))?' + \ r'(?:/(?P<exact>exact))?$', hours_detail_resource), HANDLERS.PY # inherit from BaseHandler to add the extra functionality i need to process the possibly null URL params class BaseApiHandler(BaseHandler): # keep track of the handler so the data is represented back to me correctly post_name = 'base' # THIS IS THE LIST IN QUESTION - SOMETIMES IT IS GETTING SET TO [0,1] MYSTERIOUSLY # this gets set to a list when the results are to be limited limit = None def has_limit(self): return (isinstance(self.limit, list) and len(self.limit) == 2) def process_kwarg_read(self, key, value, d_post, b_exact): """ this should be overridden in the derived classes to process kwargs """ pass # override 'read' so we can better handle our api's searching capabilities def read(self, request, *args, **kwargs): d_post = {'status':0,'statusmsg':'Nothing Happened'} try: # setup the named response object # select all employees then filter - querysets are lazy in django # the actual query is only done once data is needed, so this may # seem like some memory hog slow beast, but it's actually not. d_post[self.post_name] = self.queryset(request) # this is a string that holds debug information... it's the string I mentioned before pasting this code s_query = '' b_exact = False if 'exact' in kwargs and kwargs['exact'] <> None: b_exact = True s_query = '\'exact\':True,' for key,value in kwargs.iteritems(): # the regex url possibilities will push None into the kwargs dictionary # if not specified, so just continue looping through if that's the case if value == None or key == 'exact': continue # write to the s_query string so we have a nice error message s_query = '%s\'%s\':\'%s\',' % (s_query, key, value) # now process this key/value kwarg self.process_kwarg_read(key=key, value=value, d_post=d_post, b_exact=b_exact) # end of the kwargs for loop else: if self.has_limit(): # THIS SEEMS TO GET HIT SOMETIMES IF YOU CONSTANTLY REFRESH THE API PAGE, EVEN THOUGH # THE LINE IN THE FOR LOOP WHICH UPDATES s_query DOESN'T GET HIS AND THUS self.process_kwarg_read ALSO # DOESN'T GET HIT SO NEITHER DOES limit = [0,1] s_query = '%swith limit[%s,%s](limit,%s),' % (s_query, self.limit[0], self.limit[1], kwargs['limit']) d_post[self.post_name] = d_post[self.post_name][self.limit[0]:self.limit[1]] if d_post[self.post_name].count() == 0: d_post['status'] = 0 d_post['statusmsg'] = '%s not found with query: {%s}' % (self.post_name, s_query) else: d_post['status'] = 1 d_post['statusmsg'] = '%s %s found with query: {%s}' % (d_post[self.post_name].count(), self.post_name, s_query) except: e = sys.exc_info()[1] d_post['status'] = 0 d_post['statusmsg'] = 'error: %s' % e d_post[self.post_name] = [] return d_post class HoursDetailHandler(BaseApiHandler): #allowed_methods = ('GET',) model = HoursDetail exclude = () post_name = 'hours_detail' def process_kwarg_read(self, key, value, d_post, b_exact): if ... # I have several if/elif statements here that check for other things... # 'self.limit =' only shows up in the following elif: elif key == 'limit': order_by = 'clock_time' if value == 'last': order_by = '-clock_time' d_post[self.post_name] = d_post[self.post_name].order_by(order_by) # TO GET HERE, THE ONLY PLACE IN CODE WHERE self.limit IS SET, YOU MUST HAVE GONE THROUGH # THE value == None CHECK???? self.limit = [0, 1] else: raise NameError def read(self, request, *args, **kwargs): # empid is required, so make sure it exists before running BaseApiHandler's read method if not('empid' in kwargs and kwargs['empid'] <> None and kwargs['empid'] >= 0): return {'status':0,'statusmsg':'empid cannot be empty'} else: return BaseApiHandler.read(self, request, *args, **kwargs) Does anyone have a clue how else self.limit might be getting set to [0, 1] ?

• Overriding the save() method of a model that uses django-mptt

  - by saturdayplace

  I've been using django-mptt in my project for a while now, it's fabulous. Recently, I've found a need to override a model's save() method that uses mptt, and I'm getting an error when I try to save a new instance of that model: Exception Type: ValueError at /admin/scrivener/page/add/ Exception Value: Cannot use None as a query value I'm assuming that this is a result of the fact that the instance hasn't been stuck into a tree yet, but I'm not sure how to go about fixing this.

• Python required variable style

  What is the best style for a Python method that requires the keyword argument 'required_arg': def test_method(required_arg, *args, **kwargs: def test_method(*args, **kwargs): required_arg = kwargs.pop('required_arg') if kwargs: raise ValueError('Unexpected keyword arguments: %s' % kwargs) Or something else? I want to use this for all my methods in the future so I'm kind of looking for the best practices way to deal with required keyword arguments in Python methods.

• How to provide an inline model field with a queryset choices without losing field value for inline r

  - by Judith Boonstra

  The code displayed below is providing the choices I need for the app field, and the choices I need for the attr field when using Admin.

The attr selected for these saved does show in small print above the field, but not within the field itself. # MODELS: Class Vocab(models.Model): entity = models.Charfield, max_length = 40, unique = True) Class App(models.Model): name = models.ForeignKey(Vocab, related_name = 'vocab_appname', unique = True) app = SelfForeignKey('self, verbose_name = 'parent', blank = True, null = True) attr = models.ManyToManyField(Vocab, related_name = 'vocab_appattr', through ='AppAttr' def parqs(self): a method that provides a queryset consisting of available apps from vocab, excluding self and any apps within the current app's dependent line. def attrqs(self): a method that provides a queryset consisting of available attr from vocab excluding those already selected by current app, 2) those already selected by any apps within the current app's parent line, and 3) those selected by any apps within the current app's dependent line.

• django admin: Add a "remove file" field for Image- or FileFields

  - by w-

  I was hunting around the net for a way to easily allow users to blank out imagefield/filefields they have set in the admin. I found this http://www.djangosnippets.org/snippets/894/ What was really interesting to me here was the code posted in the comment by rfugger remove_the_file = forms.BooleanField(required=False) def save(self, *args, **kwargs): object = super(self.__class__, self).save(*args, **kwargs) if self.cleaned_data.get('remove_the_file'): object.the_file = '' return object When i try to use this in my own form I basically added this to my admin.py which already had a BlahAdmin class BlahModelForm(forms.ModelForm): class Meta: model = Blah remove_img01 = forms.BooleanField(required=False) def save(self, *args, **kwargs): object = super(self.__class__, self).save(*args, **kwargs) if self.cleaned_data.get('remove_img01'): object.img01 = '' return object when i run it I get this error maximum recursion depth exceeded while calling a Python object at this line object = super(self.__class__, self).save(*args, **kwargs) When i think about it for a bit, it seems obvious that it is just infinitely calling itself causing the error. My problem is i can't figure out what is the correct way i should be doing this. Any suggestions? thanks

• Stochastic calculus library in python

  - by LeMiz

  Hello, I am looking for a python library that would allow me to compute stochastic calculus stuff, like the (conditional) expectation of a random process I would define the diffusion. I had a look a at simpy (simpy.sourceforge.net), but it does not seem to cover my needs. This is for quick prototyping and experimentation. In java, I used with some success the (now inactive) http://martingale.berlios.de/Martingale.html library. The problem is not difficult in itself, but there is a lot non trivial, boilerplate things to do (efficient memory use, variable reduction techniques, and so on). Ideally, I would be able to write something like this (just illustrative): def my_diffusion(t, dt, past_values, world, **kwargs): W1, W2 = world.correlated_brownians_pair(correlation=kwargs['rho']) X = past_values[-1] sigma_1 = kwargs['sigma1'] sigma_2 = kwargs['sigma2'] dX = kwargs['mu'] * X * dt + sigma_1 * W1 * X * math.sqrt(dt) + sigma_2 * W2 * X * X * math.sqrt(dt) return X + dX X = RandomProcess(diffusion=my_diffusion, x0 = 1.0) print X.expectancy(T=252, dt = 1./252., N_simul= 50000, world=World(random_generator='sobol'), sigma1 = 0.3, sigma2 = 0.01, rho=-0.1) Does someone knows of something else than reimplementing it in numpy for example ?

• Ubuntu + Wacom Intuos 4 + MyPaint HELP!

  - by Sativa

  Please keep in mind I'm not that computer savvy, but I will try any suggestion so please help me out! My tablet will stop working if the USB connection is ever broken, or the Ubuntu software is being updated. Sometimes it will stop working for no reason that I can see. The lights will still be on, but it won't be responsive. It doesn't work again until I restart the laptop with the tablet plugged in, which is grating if you have to do it every 25 min. or so... I'm not sure if the issue is with the port, the tablet/cable or the driver but any suggestions would be very welcome! Also, MyPaint is frequently having hiccups. It seems to save fine but at times it will randomly close down and when I open files they're often empty. They turn into 0Kb files and only contain a single empty layer. Also very grating, considering I lose days of work for no clear reason and without any heads up. Again, I'm not sure if the issue is with the port, the tablet/cable or the driver but any suggestions would be very welcome!

• Is this over-abstraction? (And is there a name for it?)

  - by mwhite

  I work on a large Django application that uses CouchDB as a database and couchdbkit for mapping CouchDB documents to objects in Python, similar to Django's default ORM. It has dozens of model classes and a hundred or two CouchDB views. The application allows users to register a "domain", which gives them a unique URL containing the domain name that gives them access to a project whose data has no overlap with the data of other domains. Each document that is part of a domain has its domain property set to that domain's name. As far as relationships between the documents go, all domains are effectively mutually exclusive subsets of the data, except for a few edge cases (some users can be members of more than one domain, and there are some administrative reports that include all domains, etc.). The code is full of explicit references to the domain name, and I'm wondering if it would be worth the added complexity to abstract this out. I'd also like to know if there's a name for the sort of bound property approach I'm taking here. Basically, I have something like this in mind: Before in models.py class User(Document): domain = StringProperty() class Group(Document): domain = StringProperty() name = StringProperty() user_ids = StringListProperty() # method that returns related document set def users(self): return [User.get(id) for id in self.user_ids] # method that queries a couch view optimized for a specific lookup @classmethod def by_name(cls, domain, name): # the view method is provided by couchdbkit and handles # wrapping json CouchDB results as Python objects, and # can take various parameters modifying behavior return cls.view('groups/by_name', key=[domain, name]) # method that creates a related document def get_new_user(self): user = User(domain=self.domain) user.save() self.user_ids.append(user._id) return user in views.py: from models import User, Group # there are tons of views like this, (request, domain, ...) def create_new_user_in_group(request, domain, group_name): group = Group.by_name(domain, group_name)[0] user = User(domain=domain) user.save() group.user_ids.append(user._id) group.save() in group/by_name/map.js: function (doc) { if (doc.doc_type == "Group") { emit([doc.domain, doc.name], null); } } After models.py class DomainDocument(Document): domain = StringProperty() @classmethod def domain_view(cls, *args, **kwargs): kwargs['key'] = [cls.domain.default] + kwargs['key'] return super(DomainDocument, cls).view(*args, **kwargs) @classmethod def get(cls, *args, **kwargs, validate_domain=True): ret = super(DomainDocument, cls).get(*args, **kwargs) if validate_domain and ret.domain != cls.domain.default: raise Exception() return ret def models(self): # a mapping of all models in the application. accessing one returns the equivalent of class BoundUser(User): domain = StringProperty(default=self.domain) class User(DomainDocument): pass class Group(DomainDocument): name = StringProperty() user_ids = StringListProperty() def users(self): return [self.models.User.get(id) for id in self.user_ids] @classmethod def by_name(cls, name): return cls.domain_view('groups/by_name', key=[name]) def get_new_user(self): user = self.models.User() user.save() views.py @domain_view # decorator that sets request.models to the same sort of object that is returned by DomainDocument.models and removes the domain argument from the URL router def create_new_user_in_group(request, group_name): group = request.models.Group.by_name(group_name) user = request.models.User() user.save() group.user_ids.append(user._id) group.save() (Might be better to leave the abstraction leaky here in order to avoid having to deal with a couchapp-style //! include of a wrapper for emit that prepends doc.domain to the key or some other similar solution.) function (doc) { if (doc.doc_type == "Group") { emit([doc.name], null); } } Pros and Cons So what are the pros and cons of this? Pros: DRYer prevents you from creating related documents but forgetting to set the domain. prevents you from accidentally writing a django view - couch view execution path that leads to a security breach doesn't prevent you from accessing underlying self.domain and normal Document.view() method potentially gets rid of the need for a lot of sanity checks verifying whether two documents whose domains we expect to be equal are. Cons: adds some complexity hides what's really happening requires no model modules to have classes with the same name, or you would need to add sub-attributes to self.models for modules. However, requiring project-wide unique class names for models should actually be fine because they correspond to the doc_type property couchdbkit uses to decide which class to instantiate them as, which should be unique. removes explicit dependency documentation (from group.models import Group)

• Custom Django admin URL + changelist view for custom list filter by Tags

  - by Botondus

  In django admin I wanted to set up a custom filter by tags (tags are introduced with django-tagging) I've made the ModelAdmin for this and it used to work fine, by appending custom urlconf and modifying the changelist view. It should work with URLs like: http://127.0.0.1:8000/admin/reviews/review/only-tagged-vista/ But now I get 'invalid literal for int() with base 10: 'only-tagged-vista', error which means it keeps matching the review edit page instead of the custom filter page, and I cannot figure out why since it used to work and I can't find what change might have affected this. Any help appreciated. Relevant code: class ReviewAdmin(VersionAdmin): def changelist_view(self, request, extra_context=None, **kwargs): from django.contrib.admin.views.main import ChangeList cl = ChangeList(request, self.model, list(self.list_display), self.list_display_links, self.list_filter, self.date_hierarchy, self.search_fields, self.list_select_related, self.list_per_page, self.list_editable, self) cl.formset = None if extra_context is None: extra_context = {} if kwargs.get('only_tagged'): tag = kwargs.get('tag') cl.result_list = cl.result_list.filter(tags__icontains=tag) extra_context['extra_filter'] = "Only tagged %s" % tag extra_context['cl'] = cl return super(ReviewAdmin, self).changelist_view(request, extra_context=extra_context) def get_urls(self): from django.conf.urls.defaults import patterns, url urls = super(ReviewAdmin, self).get_urls() def wrap(view): def wrapper(*args, **kwargs): return self.admin_site.admin_view(view)(*args, **kwargs) return update_wrapper(wrapper, view) info = self.model._meta.app_label, self.model._meta.module_name my_urls = patterns('', # make edit work from tagged filter list view # redirect to normal edit view url(r'^only-tagged-\w+/(?P<id>.+)/$', redirect_to, {'url': "/admin/"+self.model._meta.app_label+"/"+self.model._meta.module_name+"/%(id)s"} ), # tagged filter list view url(r'^only-tagged-(P<tag>\w+)/$', self.admin_site.admin_view(self.changelist_view), {'only_tagged':True}, name="changelist_view"), ) return my_urls + urls Edit: Original issue fixed. I now receive 'Cannot filter a query once a slice has been taken.' for line: cl.result_list = cl.result_list.filter(tags__icontains=tag) I'm not sure where this result list is sliced, before tag filter is applied. Edit2: It's because of the self.list_per_page in ChangeList declaration. However didn't find a proper solution yet. Temp fix: if kwargs.get('only_tagged'): list_per_page = 1000000 else: list_per_page = self.list_per_page cl = ChangeList(request, self.model, list(self.list_display), self.list_display_links, self.list_filter, self.date_hierarchy, self.search_fields, self.list_select_related, list_per_page, self.list_editable, self)

  I want to better write this test: def test_profile_created(self): self.client.post(reverse('registration_register'), data={ 'username':'ygam', 'email':'[email protected]', 'password1':'ygam', 'password2':'ygam' }) """ Test if a profile is created on save """ user = User.objects.get(username='ygam') self.assertTrue(UserProfile.objects.filter(user=user).exists()) and I just came upon this code on django-registration tests that does not actually "create" the user: def test_registration_signal(self): def receiver(sender, **kwargs): self.failUnless('user' in kwargs) self.assertEqual(kwargs['user'].username, 'bob') self.failUnless('request' in kwargs) self.failUnless(isinstance(kwargs['request'], WSGIRequest)) received_signals.append(kwargs.get('signal')) received_signals = [] signals.user_registered.connect(receiver, sender=self.backend.__class__) self.backend.register(_mock_request(), username='bob', email='[email protected]', password1='secret') self.assertEqual(len(received_signals), 1) self.assertEqual(received_signals, [signals.user_registered]) However he used a custom function for this "_mock_request": class _MockRequestClient(Client): def request(self, **request): environ = { 'HTTP_COOKIE': self.cookies, 'PATH_INFO': '/', 'QUERY_STRING': '', 'REMOTE_ADDR': '127.0.0.1', 'REQUEST_METHOD': 'GET', 'SCRIPT_NAME': '', 'SERVER_NAME': 'testserver', 'SERVER_PORT': '80', 'SERVER_PROTOCOL': 'HTTP/1.1', 'wsgi.version': (1,0), 'wsgi.url_scheme': 'http', 'wsgi.errors': self.errors, 'wsgi.multiprocess':True, 'wsgi.multithread': False, 'wsgi.run_once': False, 'wsgi.input': None, } environ.update(self.defaults) environ.update(request) request = WSGIRequest(environ) # We have to manually add a session since we'll be bypassing # the middleware chain. session_middleware = SessionMiddleware() session_middleware.process_request(request) return request def _mock_request(): return _MockRequestClient().request() However, it may be too long of a function for my needs. I want to be able to somehow "fake" the account creation. I have not much experience on mocks and stubs so any help would do. Thanks!
