Django view being called with no kwargs
I have a django.views.generic.DetailView-based class called LocationView that is set up like this: class LocationView(DetailView): model = Location pk_url_kwarg = 'location_id', template_name = 'accounts/locations/view_location.html' And the corresponding url definition: url( r'^accounts/(?P<account_id>\d+)/locations/(?P<location_id>\d+)/$' LocationView.as_view(), name='view_location', ) When I try to access LocationView in my browser, I get the following exception: AttributeError: Generic detail view LocationView must be called with either an object pk or a slug. After much digging, I found out that somewhere along the line, self.pk_url_kwarg gets changed from 'location_id' to ('location_id', ), which causes the view to fail to retrieve the object's pk when it runs self.kwargs.get(self.pk_url_kwarg) because none of the keys in self.kwargs matches the modified pk_url_kwarg value. Why is this happening and how can I fix it? django.VERSION == (1, 11, 'final', 0) -

How Secure Is Too Secure in OAuth 2.0?
Background: I am currently on a team responsible for building an API for University College, London. I am responsible for building an implementation of OAuth which sits on top of Shibboleth that we can provide to our users. In order to keep it as secure as possible (we are going to be providing student data, so we can't take any risks here), I have implemented a nonce parameter along with a client_secret_proof parameter (the appsecret_proof that is described at sakurity.com/oauth). The difference is that in my implementation a request is made to a nonce endpoint and then this nonce value is concatenated onto the user's token then run through the HMAC algorithm so that the client_secret_proof parameter cannot be replayed. The question here is that my PM thinks this extra protection is unnecessary and just terrible for Developer Experience, but I want to try and make it as difficult as possible to MITM the connection and do as much as I can to prevent the leaking of client secrets by sloppy programming on the part of our student developers. Am I wasting my time in toughening up OAuth here, or is OAuth 2.0 inherently weak when it comes to preventing … -
Exclude a field from Wagtail Page revisions
I have a Wagtail model that extends the base Page model. I am only updating the active field programmatically via daily API import script, so I want it excluded from the CMS entirely. I'm able to exclude the active field from the CMS edit view by not including it in the "content_panels", but a value is still always included in page revisions, which is overriding my imported value. How can I have a field that is excluded from page revisions? class EmployeePage(Page): active = models.BooleanField(blank=True) first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) ... content_panels = [ FieldPanel('first_name'), FieldPanel('last_name'), ] -
How to update a form value and submit the updated form using JS

But now I want to update this {{form.UserContent.Value}} in the form and using JS then POST it again using the submit button and let django save the new value. But it stores "None" instead! I am using materialize css and django 1.11 Textarea is a must for my use. -
Error when starting Django application from VSCode
I am trying to debug an Django application using VSCode. I made sure the launch.json has the right Django setting, opened the manage.py file, then start debugging session. But the console always shows that the manage.py does not take the argument "runserver" from the launch.json and failed as it cannot find any argument. The code I tried to debug won't be hit until the user click a button to trigger the action, so I am not sure if I can open that file as the starting point when I start the debugging session. When I tried that, I got a bunch of other errors : File "C:\Python34\lib\site-packages\django\conf__init__.py", line 42, in _setup % (desc, ENVIRONMENT_VARIABLE)) django.core.exceptions.ImproperlyConfigured: Requested setting CACHES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. Not sure what is the problem, but I thought this should be a very common scenario that everyone using VSCode+Django will have. Any advise is highly appreciated. Thanks. -

Python-ldap can connect to active directory from python console but not application
I am trying to connect to an active directory using Python-ldap library. I have the following bind code: def bind_connection(): ldap_password = ******* ldap_url = 'ldaps://*******:636 ldap_login = "CN=***, CN=Users, DC=***, DC=local" ldap.set_option(ldap.OPT_X_TLS_REQUIRE_CERT, ldap.OPT_X_TLS_NEVER) l = ldap.initialize(ldap_url) l.set_option(ldap.OPT_REFERRALS, 0) l.set_option(ldap.OPT_PROTOCOL_VERSION, 3) l.set_option(ldap.OPT_X_TLS, ldap.OPT_X_TLS_DEMAND) l.set_option(ldap.OPT_X_TLS_DEMAND, True) l.set_option(ldap.OPT_DEBUG_LEVEL, 255) l.simple_bind_s(ldap_login, ldap_password) return l Importing and running this in the python console works fine.

How to set password to staging env for a django app on Heroku?
I'd like to password-protect my staging environment so it's not accessible to the public. Also, the password protection should not be tied to Django's authentication backend, so that I can test features (e.g. creating an account for user, logging in / out, etc.). How best to achieve that? -

Django-multiform with custom form field, input not being passed to view
I am using django-multiform to submit two forms to my class based view (FormView). The two forms consist of multiple custom fields that extend the BooleanField class. The trouble that I'm having is that all fields evaluate to false even if they're checked, and I don't have the same problem if I only submit one form without using the django-multiform. Here is the custom field, it's extends the boolean field to return False if unchecked, and a pre-determined list if checked. class RangeField(forms.BooleanField): def __init__(self, hand=None, *args, **kwargs): super(RangeField, self).__init__(*args, **kwargs) self.hand = hand def to_python(self, value): # Return hand as a list object to python if isinstance(value, six.string_types) and\ value.lower() in ('false', '0'): return super(RangeField, self).to_python(False) elif bool(value): return self.hand else: return super(RangeField, self).to_python(False) Here are my forms class RangeForm(forms.Form): aa = RangeField(required=False, label='AA', hand=[12, 25], widget=forms.CheckboxInput(attrs={ 'class': 'range-form-attr hidden'})) aks = RangeField(required=False, label='AKs', hand=[25, 24], widget=forms.CheckboxInput(attrs={ 'class': 'range-form-attr hidden'})) class FlopForm(forms.Form): twoc = RangeField(required=False, label='2c', hand=[0], widget=forms.CheckboxInput(attrs={ 'class': 'range-form-attr hidden'})) threec = RangeField(required=False, label='3c', hand=[1], widget=forms.CheckboxInput(attrs={ 'class': 'range-form-attr hidden'})) class RangeFlopForm(MultiForm): base_forms = OrderedDict([('range_form', RangeForm), ('flop_form', FlopForm)]) Here is my view, it does nothing but print the input in the server so I can see what's happening. class … -
Django-rest saving model against a specific user

In Django, how to render both JSON data with api and info from context dictionary
In Django, I want to render a page that includes a Chart js chart that relies on data from my database. I believe I need to implement an API for this. The same page with the chart will contain other info from the database that I think is rendered with a context dictionary and {{ variable }}. I know how to do one or the the other, but not both on the same page. Here is what I have so far. In views.py: from django.shortcuts import render from django.http import HttpResponse, JsonResponse from django.views import generic from django.views.generic import View from .models import Article from rest_framework.views import APIView from rest_framework.response import Response class ChartData(APIView): authentication_classes = [] permission_classes = [] def get(self, request, format=None): articles = Article.objects.all() correlationlist = [] nocorrelationlist = [] for corr in articles: if corr.correlation_type == "Correlation": correlationlist.append(1) nocorrelationlist.append(0) elif corr.correlation_type == "No Correlation": correlationlist.append(0) nocorrelationlist.append(1) else: pass correlation_items = correlationlist nocorrelation_items = nocorrelationlist data = { "correlation_items": correlation_items, "nocorrelation_items": nocorrelation_items, } return Response(data) The Javascript I have on the page where the chart appears is: $(document).ready(function(){ var endpoint = 'api/chart/data/' var defaultData1 = [] var defaultData2 = []; $.ajax({ method: "GET", url: endpoint, success: function(data){ … -
Override foreignkey fields to textarea in Django
i'm have a model: @python_2_unicode_compatible class TypologyItem(Base): ... action = models.ForeignKey( Action, null=True, on_delete=models.CASCADE, verbose_name=_('action')) subject = models.ForeignKey( Subject, null=True, on_delete=models.CASCADE, verbose_name=_('subject')) brand = models.ForeignKey( Brand, null=True, on_delete=models.CASCADE, verbose_name=_('brand')) ... def save(self, *args, **kwargs): if not self.id: self.name ='{} {} {}'.format( self.action.name, self.subject.name, self.brand.name ) self.slug = slugify(self.name, allow_unicode=True) super(TypologyItem, self).save(*args, **kwargs) def __str__(self): return self.name And it is necessary, for convenience, to make a form in which each field corresponding to the related model is a Textarea. The data entered in these fields should be parsed line by line, and for each of the lines you need to create an instance of the corresponding model, and only then create the number of objects represented by this form equal to the multiplied number of each Textarea field. That is, if action1, action2, action3 was entered in the action field, subject1, subject2, subject3 was entered in the subject field, and in the brand field, respectively, brand1, brand2, brand3, then the output should look something like this: <Typology: Action1 subject1 brand1>, <Typology: action2 subject1 brand1>, <Typology: action3 subject1 brand1>, ... <Typology: action3 subject3 brand3>. Initially, I thought about the modelForm and did try to do something like this: class TypologyForm(forms.ModelForm): class Meta: … -

And the grades are specific to students. As it is apparent form the models, Subject contains chapter, Chapter consists of Questions. Each question can have multiple grades. All the values for the grades are stored in the Rating table which in turn is connected to the Data table using foreign key. I am using django rest framework for creating the APIs. Now for fetching I have to hit the Rating Table to get the schema as well as the data.

How do I make sure to fetch the whole schema with current values. I was thinking I could do something … -
Serve media files in Django as seekable (with HTTP PartialResponse)
I know that it will be easier to serve these video files with another server like Apache, but I can't use it now. I have some uploaded videos in the media folder using Django (using those FileField models). Now, I have set up a way to stream those videos, but the problem is, the video is not seeking. This can be fixed by implementing some sort of Streaming Response (maybe this, but I am unsure and don't know how to do.) that implements HTTP PARTIAL RESPONSE. Any way to implement this? I'm using media files as specified here (see the MEDIA_ROOT, MEDIA_URL parts.) My settings.py - MEDIA_ROOT = os.path.join(BASE_DIR, "media/") MEDIA_URL = "media/" ...
