add image field in UserCreationForm in django
I'm new to python and Django and trying to build a user profile.I have created user form directly in forms.py but don't know how to add user profile picture in registration and display it in profile template.

how Django reads http request and sends http response
If I write a simple http server in C. I can read http request through a file descriptor generated by accept() function in a while loop. And I can send http response to client through that file descriptor. In Django I know the HttpRequest object will be passed to view function as a argument, but I want to know which function reads the HttpRequest through the socket and generate a HttpRequest object? I know view function will return a HttpResponse object. But which function will send the actual http response to the client? And where is the while loop? -

How do I include the id field in a django form?
I'm trying to create a simple form that pulls up a record by asking its ID in the form. views.py class Bill(models.Model): """ Represents a single purchase made by a customer at a business. """ business = models.ForeignKey(Businesses) customer = models.ForeignKey(User, blank=True, null=True) charge = models.ForeignKey(Charge, blank=True, null=True) amount = models.IntegerField(verbose_name='Purchase amount (in cents)', validators=[MinValueValidator(0)]) tip = models.IntegerField(verbose_name='Tip amount (in cents)', validators=[MinValueValidator(0)]) comments = models.CharField(max_length=255, blank=True, null=True) timestamp = models.DateTimeField(auto_now_add=True) forms.py from django import forms from django.forms import ModelForm from transactions.models import Bill class BillSelectForm(ModelForm): class Meta: model = Bill fields = ('id',) views.py @login_required(login_url='/sign-in/') def select_bill(request): """ Finds a bill based on its ID number.

Thoughts? -

Outputing images using xhtml2pdf: URI=None in xhtml2pdf\util.py
I’m trying to output PDF with images using xhtml2pdf in Django 1.10.6. Using a wrapper like django-xhtml2pdf won’t fit me since the handling of the file is somewhat specific (long story short I try to upload files using post method without any referrencing models or databases, and all have to be done in memory).

Can you change the name of the Django admin 'is_staff' flag?
I want to rename the "is_staff" flag to "is_volunteer" to better model the use-cases of our system. The function of this flag should stay exactly the same: only users with is_volunteer = True can access the admin interface. I haven't dug through the django.contrib.auth library to determine how rigid the model is, but I'm curious if anyone has done this before. -

How to get Twilio's RequestValidator to work
I'm not sure why this doesn't work. I have been looking at Twilio's documentation here, and I tried just making it a function call, but that didn't work, so I put it directly in my view, and it still didn't work. It always returns 403.

Change group in Django admin is very slow
Django 1.11 If I click Groups in Django admin site, I can see a list of groups. Namely, the address is http://localhost:8000/admin/auth/group/ I monitor the CPU usage in terminal. Python is consuming 4-5 % now. I have organized 4 groups. So, if I click any group, the server just calculating something for several minutes. The address now is like http://localhost:8000/admin/auth/group/6/change/ Maybe about 5 minutes the server is calculating something. And Python is now consuming 100 % of CPU resources. Well, Django admin is analyzing something. I have about 23-25 models. Well, this is not a very big number of models. Each model is 3 standard permissions (add, change, delete). And I created one permission myself in the Meta class of a model. So, as soon as "Change group" page is in front of me with available permissions and chosen permissions, CPU consumption by Python is again 4-5 %. Could you comment on this? Is it curable? -

For single user to multiple users Django app
i have a chatbot web application that simulate a customer service, where it takes the input and shows the output via request/response and some back-end python files.So far it is working for one user at a time. Now i want it to talk to multiple users at the same time where each user has his/her chatting page and cabot application. i found out that i should use: Django multi-session==> to create a session for each user. Sub-process==> to create a chatbot app of each user session. The problem i don't know how?!. So,if these any resource to example on how to implement it that will be very helpful. PS: i'm using Django 10.1,Python3 and new in the Django development field. thank you, -

Using Chosen.js with Django
Hello Im trying to implement chosen.js into my Django project and so far it works great. I only have one issue which I cannot solve. I have a model where "language" is a ChardField. I wanted to let the User choose more than one language so I tried to use chosen Multiple. Since a Charfield can only hold one Value so I used Django Multiselect. Now the Chosen.js is not working anymore and I have no idea what to do. Models: from multiselectfield import MultiSelectField class UserProfile(models.Model): language = MultiSelectField(verbose_name=_(u"Content Language"), max_length=40, choices=settings.LANGUAGES,default='en')` Forms: class UserProfileForm(forms.ModelForm): class Meta: model = UserProfile fields=[ 'language', ..... ] Template: {% load widget_tweaks %} {% csrf_token %} <span>Content language {{ form.language|add_class:"chosen-select" }}</span> So the question is how do I get the normal chosen.js input field to a multiple chosen field (with Django)? I know there is the possibility to add a multiple field to the forms but this messes up my hole code. -
Django Models: combine multiple fields entries for one field

The question I have is how can I combine the challengeone, two, three, four, five and get the total points and have a field totalpoints where the field points are added to that one automatically -
Django REST auth - users stored in external service
I've been wondering the best way to handle the case where a Django is used in a service-oriented architecture, so individual Django applications do not maintain their own user stores. One service maintains the user store, and others must call it in order to retrieve user information. So far example, here is how I was thinking of building a custom authentication class in Django REST to handle this: class SOAAuthentication(authentication.BaseAuthentication): def authenticate(self, request): token = request.get_token_from_auth_header() if not remote_auth_service.is_token_valid(token): raise AuthFailed('Token is invalid') user_properties = remote_users_service.get_user(token): # user_properties is a dict of properties if not user_properties: raise AuthFailed('User does not exist.') user = MyCustomUserClass(**user_properties) return (user, 'soa') So no user info would get persisted in the Django application's database, and permission classes could interrogate the instance of MyCustomUserClass to figure out what groups a user belongs to. Would this approach work for simple group-based authorization? My think is that I don't need object-level permissions, so there's no need to create rows for my users in the Django database. -
How to debug django ajax function when using djangorestframework decorator?
How to debug ajax function when using djangorestframework decorator. @api_view(['POST', ]) def authfb(request): require_more_data = True if request.method == 'POST': first_name = request.data['fb_first_name'] last_name = request.data['fb_last_name'] fb_picture = request.data['fb_picture'] fb_friends_number = request.data['fb_friends_number'] fb_username = request.data['fb_username'] fb_id = int(request.data['fb_id']) fb_link = request.data['fb_link'] username = fb_username.replace(' ', '') # print(username) password = '112358' user = auth.authenticate(username=username, password=password) Example of code. Django doesn't tell about any errors, when calling view functions through ajax request. This makes me using print and searching the wrong line manually and still leaves no idea what exactly is wrong. How to debug it, how to make django log errors as usual? -
Local OP file taking lower priority than Django default translation
In my settings.py, I have LOCALE_PATHS = ( os.path.join(BASE_DIR, "locale"), ) So local OP file should take higher priority than Django's default translation. However, the translation for some words which have a default translation, say first name and last name, are still the default 名字 and 姓氏, rather than 姓 and 名, which are what I've specified in /project/app/locale/zh_Hans/LC_MESSAGES/django.po: #: models.py:51 msgid "first name" msgstr "姓" #: models.py:55 msgid "last name" msgstr "名" I can bypass this issue by using Contextual markers, but it's merely a workaround which isn't "semantic". Also, I want to know why default translation can override the one in LOCALE_PATHS. -
How to create unique method for url parameters?
This is my get method: if request.method == 'GET': myObject = myObjectClass.objects.all() serializer = myObjectSerializer(myObject, many=True) return Response(serializer.data) Let's assume that response looks in this way: [ { "id": 1, "data1": 12, "data2": "example1" }, { "id": 2, "data1": 11, "data2": "example3" }, { "id": 3, "data1": 12, "data2": "example3" } ] I would like to create method using URL http://localhost:8000/data/?data1=12 to get in response: [ { "id": 1, "data1": 12, "data2": "example1" }, { "id": 3, "data1": 12, "data2": "example3" } ] My problem is that I would like to create unique method. For instance we could use URL http://localhost:8000/data/?data2="example3" and in response we would get: [ { "id": 2, "data1": 11, "data2": "example3" }, { "id": 3, "data1": 12, "data2": "example3" } ] I wonder if this is possible?

How do I add a FlatPageAdmin?
Welcome friends I need your help. I would like to use FlatPageAdmin. Like in the example above. from django.contrib import admin class FlatPageAdmin(admin.ModelAdmin): fieldsets = ( (None, { 'fields': ('url', 'title', 'content', 'sites') }), ('Advanced options', { 'classes': ('collapse',), 'fields': ('registration_required', 'template_name'), }), ) https://docs.djangoproject.com/en/1.11/ref/contrib/admin/#django.contrib.admin.ModelAdmin.fieldsets It may of course be very simple, but I don't know, how to do this. this my admin.py from django.contrib import admin from django.utils.translation import ugettext_lazy as _ from .models import Order from django.http import HttpResponse from django.core.urlresolvers import reverse class OrderAdmin(admin.ModelAdmin): list_display = ['id', 'name', 'email'] list_filter = ['name'] admin.site.register(Order, OrderAdmin) I'm trying. But whatever I do I always get: raise AppRegistryNotReady("Apps aren't loaded yet.") django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. Although I add admin.site.unregister(FlatPage) admin.site.register(FlatPage, FlatPageAdmin) How to solve a problem ? I would appreciate your help
