Django REST: CRUD on Through Table, Many-to-Many relationship

Django cant see my toolbar
Hello I have a common problem in Django like Django can't see .. OK this time Django can't see my beautiful toolbar Terminal doesnt show any error. This is my cms_toolbar.py placed in my "aktualnosci" folder from django.utils.translation import ugettext_lazy as _ from cms.toolbar_pool import toolbar_pool from cms.toolbar_base import CMSToolbar from cms.utils.urlutils import admin_reverse from .models import * @toolbar_pool.register class PollToolbar(CMSToolbar): supported_apps = ( 'aktualnosci', ) watch_models = [Aktualnosci] def populate(self): if not self.is_current_app: return menu = self.toolbar.get_or_create_menu('poll-app', _('Aktualnosci')) menu.add_sideframe_item( name=_('Lista aktualnosci'), url=admin_reverse('aktualnosci_aktualnosci_changelist'), ) menu.add_modal_item( name=_('Dodaj aktualnosc'), url=admin_reverse('aktualnosci_aktualnosci_add'), ) Of course Django can't see it and ignore it. My question is - how to force Djnago to see it Screaming doesnt help! -

Django signals working yet one is giving unexpected results
I dislike having people go through the trouble of reviewing my code but even after trying for hours, I have no idea what the problem is. I didn't have a clear way of describing my question's title but I tried. I am building a College Management System. I have two apps at the moment. One is for accounts and the other is called klass. I have extended the default user and have added a boolean field of 'in_class' which I will be using as a check to do stuff later. Below is an overview of my accounts.models.py: accounts.models.py from django.db import models from django.contrib.auth.models import BaseUserManager, AbstractBaseUser class User(AbstractBaseUser): email = models.EmailField( verbose_name='email address', max_length=255, unique=True, ) date_of_birth = models.DateField(null=True) is_active = models.BooleanField(default=True) is_admin = models.BooleanField(default=False) is_teacher = models.BooleanField(default=False) is_student = models.BooleanField(default=False) is_parent = models.BooleanField(default=False) in_class= models.BooleanField(default=False) bio = models.TextField(blank=True, help_text='write something about yourself...') # goes on... I am not utilizing the permissions, i am using a role-based approach. The only difference is i've added the boolean fields to my user model instead of creating another model for the roles. Below is an overview of my klass.models.py: klass.models.py from django.db import models from accounts.models import User from django.db.models.signals import post_save, … -

Chatfuel bot - user validation
I have been reading a LOT seriuosly a lot of how can I implement this flow to my bot, for example: The user types his/her username I get the data written by the user I search in my Django Rest API if the user actually exists and then return to he/she the tasks he/she need to complete for the end of the week. I know that I have to use JSON plugin, and User Input, but what I don't know how to do, is obtain what the user type. Until now I got this URL setup in my JSON plugin: https://helloworld.herokuapp.com/post?username={{username}} so this mean that I have a running server. But then what? I read this: API integration and also this setup server side logic But step 3 is what I don't know how to develop, I achieve this: class GetView(TemplateView): template_name = 'profiles/get.html' def geturl(self, request): # url = 'https://helloworld.herokuapp.com/post?username={{username}}' # parsed = urlparse.urlparse(url) # return HttpResponse(urlparse.parse_qs(parsed.query)['username']) username = self.request.query_params print(username) url = 'https://helloworld.herokuapp.com/post/' + 'username' + username But I think i'm not even close to find the solution. -

CBV or Functional View for JsonResponse
I am new to creating API endpoints using Django. Which is a better way to handle API requests and process JsonResponse? Should I do it in a Class-Based View? Or a Functional View? I would assumed CBV would be an overkill since people tend to use CBV for the generic-view inheritance. Since I am merely sending back a Json object, i would consider it unnecessary and thus a Functional view would suffice. However, I am not too sure what exactly are the other components of CBV and FV that would matter and make the difference. If there is one view better over another view, can you please tell me with reasons why one is preferred over another. Cheers. -
How can I change email sender's name in django
I'm creating email system in my django project and faced to next question: Send email from custom email sender name, f.e. sending email from gmail(btw it works in my project) requires sending messages only from gmail account, same thing with smtp-pulse, sendgrid and etc. . My question is: May I use any of already configured smtp servers in my case, or I only need to create my own using smtplib(f.e) and configure it? Tried: DEFAULT_FROM_EMAIL = 'support@site.com' SERVER_EMAIL = 'support@site.com' EMAIL_HOST = 'smtp.gmail.com' EMAIL_PORT = 2525 EMAIL_USE_TLS = False EMAIL_HOST_USER = 'user@gmail.com' EMAIL_HOST_PASSWORD = 'password' This one doesn't work.

Django convert raw SQL ordering to QuerySet API
I'm trying to perform natural ordering on CharField for model (here simplified version): class House(models.Model): number = models.CharField(max_length=32) def __str__(self): return str(self.number) >>> House.objects.all() <QuerySet [<House: 2>, <House: 1>, <House: 4>, <House: 3>, <House: 1b>, <House: 2b>, <House: 1c>, <House: 13c>, <House: 10>, <House: 2e>, <House: 3ab>]> I have managed to order it by raw SQL query: House.objects.raw("SELECT * FROM entry_house ORDER BY(substring(number, '^[0-9]+'))::int, substring(number, '[0-9].*$')") But I need to get QuerySet object not RawQuerySet (for our current pagination implementation). Iterating over all raw queryset is not an option because of huge amount of data. How can I convert result of RawQuerySet to QuerySet or even better, how to convert this raw SQL query to Django QuerySet API? -
Pass attributes from a Cutom Field to a Custom Widget template
I want to create a custom Field and a custom Widget. I'm trying to do this using ModelForms. How can I pass arguments from the Field to the Widget but not as widget attributes, similar to how {{ widget.name }} is passed. field_name = CustomField(obj_original=ALPHA, obj_type=100) I want to use this values in the widget template as conditional and/or as values for template tags(do some manipulation), so this is why I don't want them in attributes(the attribute will appear in the html elements), this don't. I know I can pass multiple attributes in widget, but I need then to remove them from attributes and attached as direct properties/attributes of the widget. I want to be passed in the Field, not in Widget. I check in django source ChoiceField and SelectField but it is not very clear for me. -
updated file name in django
This is an admin form handler, for example I upload a test.txt file in the django admin panel: def save_model(self, request, obj, form, change): if 'torrent_file' in form.changed_data: print("file has changed: ") print(obj.file) else: print("file has not changed") super(FileAdmin, self).save_model(request, obj, form, change) here I get the original file name from the upload form, but by fact the file is saved with another name if there is already a file with this name, but in the above code i get only the original name in all cases, how to can I get the changed/updated file name that was saved?.. -

Modifying a Django Rest Framework Request
I have a Django rest framework api set up, and I'm trying to insert the current time into incoming PUT requests. I currently have: class ItemViewSet(viewsets.ModelViewSet): queryset = Item.objects.filter(done = False).order_by('-time') serializer_class = ItemSerializer paginate_by = None def list(self, request, *args, **kwargs): self.object_list = self.filter_queryset(self.get_queryset()) serializer = self.get_serializer(self.object_list, many=True) return Response({'results': serializer.data}) This handles partial updates, but I would like to be able to send a request setting an Item to done = True and have the api also insert a unix timestamp into the data sent to the serializer. Could I alter the request object like this, or is there a better way? def put(self, request, *args, **kwargs): request.data['time'] = time.time() return self.partial_update(request, *args, **kwargs) -
Why does my django cache return nothing? Not even 'None'
I have the following three functions. The bottom function calls on the top two functions. I will get an error when multiplying the variables c=m*b 'unsupported operand type(s) for *: 'NoneType' and 'float'' and as you can see m returns nothing. So my two problems are that btc_to_hourl3 does not show 'None' or a value (and therefore skips the if statement). And secondly when printing totalUserL3hours(user1) in last function it prints nothing even though the function called shows a cached variable? def btcToHourL3(): btc_to_hourl3 = cache.get('btc_to_hourl3') print("btc to hourl3 cached is : ".format(btc_to_hourl3)) #shows as nothing when is something? if btc_to_hourl3 is None: main_api = 'https://api.nicehash.com/api?method=balance&id=keyhere' json_data = requests.get(main_api).json() balance1 = json_data['result']['balance_confirmed'] print("Nice hash L3 balance is: {}".format(balance1)) btc_to_hourl3 = float(balance1)/totalMachineHoursWorkedMonthL3() m = float(btc_to_hourl3) print("Total btc to every hour is: {}".format(btc_to_hourl3)) cache.set('btc_to_hourl3', m, 900) #cache for 15 mins return float(btc_to_hourl3) def totalUserL3hours(user1): user_L3_hrs = cache.get('user_L3_hrs'+user1.username) print("User l3 cache hours are {}".format(user_L3_hrs)) ####Prints 'None' when it is none ie after 1800secs.

How can I add the `order_status_count` to as the same level as the `results` list?
