Django-Channels 2 not persisting session data set in `connect`
channels==2.1.2 | channels-redis==2.2.1 | daphne==2.2.0 | Django==1.11.6 I've upgraded to Channels 2 specifically for the ability to access and modify the session from within a consumer (and access it in a view), but that doesn't seem to be working.

How to perform an F() query with datetime field?
I want to do a query based on two fields of a model, a date, offset by an int, used as a timedelta model.objects.filter(last_date__gte=datetime.now()-timedelta(days=F('interval'))) I am using Django 2.0 and db.sqlite3 I found some sources source 1 and source 2 but they were not helpful. some suggested to use duration field, but I want the interval to be entered in days desperately, whenever I use duration field , the admin needs to enter that in [days hh:mm:ss] in admin forms. And some gave a method model.objects.filter(last_date__gte=datetime.now()-timedelta(days=1)*F('interval')) which isn't working in db.sqlite3 and returning errors. Please suggest me some solution,like admin using duration field and entering only days or some solution with integer field of days. -
Base64ImageField returns full path only when parameter context={"request": request} added to it - Is there any other way
I currently have a Base64ImageField which works totally fine. The only problem I am having is sometimes it returns back an incomplete path. It skips the domain name but the rest of the path is fine.The reason its skipping the domain name is because I do not pass in the parameter context={"request": request} during serialization.The reason for that is because sometimes I do not have access to the request object.In other words this works fine jsonObject = Serializer(model_instance,context={"request": request}).data and this one skips the domain name from the image field jsonObject = Serializer(model_instance).data My question is how can I make it return the full path using the second example when I do not have to the request object ? Or is there any way for me to obtain the request object. When its not available ? I have this serializer in my code class Serializer_Employer_TX(ModelSerializer): user = Serializer_User() employer_image = Base64ImageField(max_length=None, use_url=True, required=False) class Meta: model = modelEmployer fields = [ 'user', 'employer_zip', 'employer_image', ] -
tastypie group by value
Using tastypie. I have the following simple model: class Autocomplete(models.Model): tablename = models.CharField(max_length=50, blank=True) # fieldname = models.CharField(max_length=25, blank=True) # value = models.CharField(max_length=50, blank=True) # class Meta: managed = False db_table = 'autocomplete' And the following ModelResource: class AutocompleteResource(ModelResource): counter = fields.CharField() class Meta: queryset = Autocomplete.objects.values('fieldname').annotate(counter=Count('fieldname')) resource_name = 'autocomplete' My goal is to group by the fieldname and return a result like this: fieldname | counter -----------+------- somefield1 | 177 somefield2 | 13926 somefield3 | 7331 Instead, tastypie throws back the following: error_message: "invalid literal for int() with base 10: ''", I'm probably missing something very basic here. Is it looking for the id but can't find it, because the values() call has removed it? How can I return a result that has different fields than the original model? I've spent way too much trying to figure this out, hope you guys can point me in the right direction. Thank you! -
Django + WSGI: No HTTP_COOKIE in environ
I've followed numerous examples, but the only one that does not return errors are the implementations of the two functions below. There doesn't seem to be an HTTP_COOKIE key in the environ. The request value only gets set with POST and GET. Think something is wrong with my setup, because none of the common usage patterns I've seen online like request.POST don't work. This is on the Django 1.11 development server, so if there will be differences between this and production (apache, nginx, lighttp) please let me know.

How do I get text from the database to keep my paragraphs separated on my blogging website?

Dynamic Django apps
I searched for a long time how to create a "plugin" framework in Django, without success. You can add some support for plugins, but having apps with full support for models, urls etc. is a hard thing. Let's start from the beginning. I started an application using django that is wanted to be extended by plugins in the future. I don't know which features vendors will add to that application, so they must be able to add database models too. If I now say, let a plugin be a django app, I have the problem that django apps are not loaded dynamically during startup. I have to manually and hardcodedly add the app into my settings.py, add the urls to urls.py etc. I now created a simple plugin system that * searches for django apps in a plugins/ directory, and includes them into the "INSTALLED_APPS" dict, by adding that code INTO settings.py directly * adds Interfaces that can be implemented by plugins to automatically add e.g. urls into the root urls.py by collecting that implementations automatically. Everything works, but one thing: I'd like to add a "shadowed" Plugin model to my database that holds the metadata of the installed plugins. … -
Django Vue.js - Different default values for multiselect list

Each time the result is the same: As a default, it renders "Snapchat". I want to manipulate attribute, because I am generating many multiselect lists with different default values -

How To Model Mapping Table in Django
I'm building a Django app that needs to represent which students are in which classes. If I were doing this in SQL I'd have three tables.

But is there a "Djangonic" way to represent a mapping between two classes? -

I'm using Django 2.0 I have a model with two datetime fields class AmountGiven(models.Model): amount = models.FloatField(help_text='Amount given to the contact') _given_date = models.DateTimeField( db_column='given_date', default=datetime.now, ) promised_return_date = models.DateTimeField( blank=True, default=None, null=True, ) @property def given_date(self): return self._given_date @given_date.setter def given_date(self, value): self._given_date = value def clean(self): print(self.given_date) if self.given_date: if self.given_date.date() > datetime.today().date(): raise ValidationError({ 'given_date': _('The given date was in the future') }) if self.given_date and self.promised_return_date: if self.given_date > self.promised_return_date: raise ValidationError({ 'promised_return_date': _('Promised return date can not be earlier than given date') }) I have to perform following validations on given_date and promised_return_date given_date is not in future if promised_return_date i. promised_return_date is not in past to given_date I'm using mixer to generate model data test_models.py @pytest.mark.django_db class TestAmountGiven(TestCase): def test_model_add_amount_given_in_future(self): amount_given_in_future_1_day = mixer.blend( 'transactions.AmountGiven', given_date=datetime.now(get_localzone()) + timedelta(days=1), promised_return_date=datetime.now(get_localzone()) + timedelta(days=300) ) self.assertRaises(ValidationError, amount_given_in_future_1_day.clean) assert str(amount_given_in_future_1_day) == str(amount_given_in_future_1_day.amount), \ '__str__ should return amount string' But this test is returning no ValidationError or any error.
