I'm trying to access an image passed down from context dictionary in a Django template as a background-image, like this: <div style="background-image:url('{{city.city_image.url}}');"> But it doesn't seem accessible from HTML or CSS. -

Django Delete an object via Post request
I want to delete an object via clicking on a glyphicon wrapped in a form. To do this, my function looks like this: def deleteHabit(request, id): print('deleteHabit') habit_to_delete = get_object_or_404(Habit, id=id) print(habit_to_delete) if (request.method == 'POST'): form = HabitForm(instance=habit_to_delete) if form.is_valid(): # checks CSRF print('delete') # normally habit_to_delete.delete() return redirect('renderOverview') # wherever to go after deleting else: # Not Working return render(request, 'overview/habit_delete_confirm', args) My understanding of Post and Get is the 'Post' condition does roughly the deleting part and the 'Get' condition renders a confirmation page for example to confirm the deletion. However, the object will be deleted, but by clicking the form it redirects to success_url and does not show a confirmation page. What's wrong on the code snippet above? -
Importing models from deployed django project in Heroku
I have been working in two projects for a while. One is a Django project where I have a web and all my logic (models, algorithms, etc). The other one is a Scrapy project. This one is the one that take care of collecting new data that it's being stored in the Django Database. While I was working locally there wasn't any problem but now that I've deployed both projects to two different heroku apps I began to have this problem: My scrapy project is importing the Django models in this way: - In my settings.py in my scrapy project I've this: import sys sys.path.insert(0, '/home/guillermo/Documents/project/django_project') #(2) import os os.environ['DJANGO_SETTINGS_MODULE'] = 'my_project.settings' and then in my files where I need a django model I do this: from base_project.models import New where New is a model in my app "base_project". Now, I don't know what to put where I put my django directory in line (2). Any help on that would be really useful as this is my project degree as an engineer and I'm looking to finish it as soon as possible. Thanks! -

django.db.utils.OperationalError: no such table -- Known error location, unknown why
I have a django app in production, and working. But when I try to setup a new version of the app, I get this error when running the initial migrate command that generates the SQLite db: django.db.utils.OperationalError: no such table: badges_badge The stack trace points to this method as the problem: File "/home/me/Developer/app/src/badges/models.py", line 69, in all_manually_granted obj.pk for obj in self.get_queryset() Here's the relevant code in badges/models.py: class BadgeManager(models.Manager): def get_queryset(self): return BadgeQuerySet(self.model, using=self._db).order_by('sort_order') ... def all_manually_granted(self): # build a list of pk's for badges that have no prerequisites. pk_manual_list = [ obj.pk for obj in self.get_queryset() # <-- OFFENDING LINE OF CODE if Prereq.objects.all_parent(obj).count() == 0 ] return self.filter(pk__in=pk_manual_list).order_by('name') class Badge(models.Model, IsAPrereqMixin): name = models.CharField(max_length=50, unique=True) ...

Creating histogram bins from Django queries
I'm trying to create bins with the count of prices to be used for a histogram. The code I've written seems to end in a infinite loop (or at least the script is still running after an hour). I'm not sure how to do it correctly. I hope someone can help. Here is the code I wrote: from itertools import zip_longest def price_histogram(area_id, agency_id): # Get prices and total count for competitors query = HousePrice.objects.filter(area_id=area_id, cur_price__range=(1000,30000)).exclude(agency_id=agency_id) count = query.values('cur_price').annotate(count=Count('cur_price')).order_by('cur_price') total = query.count() # Get prices and total count for selected agency query_agency = HousePrice.objects.filter(area_id=area_id, agency_id=agency_id, cur_price__range=(1000,30000)) count_agency = query_agency.values('cur_price').annotate(count=Count('cur_price')).order_by('cur_price') total_agency = query_agency.count() # Make list for x and y values x_comp = [] y_comp = [] x_agency = [] y_agency = [] bin_start = 0 bin_end = 1000 _count_comp = 0 _count_agency = 0 for row_comp, row_agency in zip_longest(count, count_agency, fillvalue={}): while bin_start < int(row_comp['cur_price']) < bin_end: _count_comp += row_comp['count'] _count_agency += row_agency.get('count', 0) bin_start += 1000 bin_end += 1000 x_comp.append(str(bin_start) + "-" + str(bin_end) + " USD") x_agency.append(str(bin_start) + "-" + str(bin_end) + " USD") y_comp.append(_count_comp/total) y_agency.append(_count_agency/total_agency) return {'x_comp': x_comp, 'y_comp': y_comp, 'x_agency': x_agency, 'y_agency': y_agency} I'm using Python 3.5 and Django 1.10. -
Django Template Foreign Key Check

Django: Read Uploaded Excel File

New users can't log in. Django
I'm using a view to create new users in Django. And then I have another view to log them in. But when I create a user, and I try to log in with authenticate(username=username_post, password=password_post), I get None, so it displays in the template 'Wrong username or password.'. In my database, I see new registers every time I create a new user. However, as the password is encrypted, I can't say if the problem is the login view, or the register view. However, the super user that I created through the command line after I first installed django, is able to login with no problem, so that makes me thing that the problem is when I create the user. These are my Login and Register views: class Login(View): form = LoginForm() message = None template = 'settings/blog_login.html' def get(self, request, *args, **kwargs): if request.user.is_authenticated(): return redirect('settings:index') return render(request, self.template, self.get_context()) def post(self, request, *args, **kwargs): username_post = request.POST['username'] password_post = request.POST['password'] user = authenticate(username=username_post, password=password_post) if user is not None: login(request, user) return redirect('settings:index') else: self.message = 'Wrong username or password.' return render(request, self.template, self.get_context()) def get_context(self): return {'form': self.form, 'message': self.message} class Register(CreateView): success_url = reverse_lazy('settings:login') model = User … -

Django - How can I create POST with foreign key defined in URL?
I wonder how can I create object POST with defined ID. Let's assume that I have for instance table User with columns id,name and table Object with columns id,id_users,sth where id_users is a foreign key of id from User table. I would like to have such URL /users/{id}/object and I would like to create object for user with defined ID in URL. For example this is my URL /users/1/object (url(r'^users/(?P<myID>[0-9]+)/object/$', views.UserObject) - should be okey) and body of POST: { "id": 2, "sth": 123 } In this case it should be added to my database: { "id": 2, "id_users": 1, "sth": 123 } For User with id equals 1 we have created object with id equals 2 and sth equals 123. I don't know what my view should look like? I always did POST in this way: @api_view(['GET', 'POST']) def ObjectList(request): if request.method == 'POST': serializer = ObjectSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) I have deleted duplicated posts, because I have explained here how my database and relations between tables look like.

How to get image from a custom django registration view
I'm using using django-registration (redux) and I have created a custom register view for my purposes. class MyRegisterView(RegistrationView): form_class = MyCustomForm def register(self, form_class): new_user = super(MyRegisterView, self).register(form_class) cm = CustomModel() # cm.profile_picture = form_class.cleaned_data['profile_picture'] cm.save() return new_user In order to get the image I would have to instantiate the form as form_class = MyCustomForm(request.POST, request.FILES) And to do that request should be added in register method as def register(self, request, form_class) Since register method is overridden from RegistrationView class the signatures do not match. What's the correct way to do it? -

Foreign Key to single attribute from another entity in Django
I want to create database model in django and define a foreign key.

New Django Cookiecutter project using older project's Postgres DB
I am creating a new django cookiecutter project (for clarification - the first on Python 2.7, this new one on Python 3.6). I just did the following: brew install python3 create the virtualenvironment with venv activated the venv installed cookiecutter setup a new project pip install -r requirements/local.txt createdb (project_name) (The projects aren't the same name) I then get to running the initial migrations, and run into an issue with Postgres. When I run "python manage.py migrate" I get the following error: django.db.utils.ProgrammingError: relation "django_site_domain_a2e37b91_uniq" already exists I see the new postgres db, and my Django settings are pointing to this new db. DATABASES = { 'default': env.db('DATABASE_URL', default='postgres:///inventorymaster'), } DATABASES['default']['ATOMIC_REQUESTS'] = True When I then run python manage.py runserver, I can login to the new project with the username/password for the first cookiecutter project. The second project is referencing the first project's db - but this doesn't make sense to me seeing the settings are pointed to the new db. How is the new project referencing the first, older projects user table to allow me to login and making the django.db.utils.ProgrammingError? -
MySQL (MariaDB) backend for Django under Python3 on Debian
I am attempting to configure Django running under Python3 on a Debian box to use MariaDB as its backend.

Did you install mysqlclient or MySQL-python? Now, obviously, MySQLdb doesn't work on Python3 and although I have installed the mysql connector package doesn't seem to work. If I try using the connector recommended by MySQL i.e. DATABASES = { 'default': { 'ENGINE': 'mysql.connector.django', 'NAME': 'foo', 'USER': 'tim', 'PASSWORD': 'swordfish', 'HOST': 'localhost' then I get a load of grief culminating in django.core.exceptions.ImproperlyConfigured: 'mysql.connector.django' isn't an available database backend. Try using 'django.db.backends.XXX', where XXX is one of: 'mysql', 'oracle', 'postgresql', 'sqlite3' Error was: cannot import name 'BaseDatabaseFeatures' Any suggestions? -
How to set field in model that was not defined in Meta class
In django, how do we set fields that were not defined in class Meta?` I have this model: class User(models.Model): user_name = models.CharField(max_length=32, unique=True) email = models.EmailField(unique=True) first_name = models.CharField(max_length=32) last_name = models.CharField(max_length=32) password_hash = models.CharField(max_length=64) password_salt = models.CharField(max_length=64) and this form: class ContactForm(ModelForm): password = forms.CharField(widget=forms.PasswordInput()) repeat_password = forms.CharField(widget=forms.PasswordInput()) class Meta: model = User fields = ['user_name', 'email', 'first_name', 'last_name'] def clean(self): cleaned_data = super(ContactForm, self).clean() password = cleaned_data.get('password') repeat_password = cleaned_data.get('repeat_password') if password is not None and repeat_password is not None: if password != repeat_password: raise forms.ValidationError("Passwords do not match.") password_validate = password_validate = password_validation.validate_password(password) if password_validate is not None: raise password_validate I only want the user to be able to set user_name, email, first_name and last_name fields. In clean(self) I check if the entered passwords match and if they are valid. What I want to do now is to set password_hash and password_salt of my model User. How can this be done? -
Django makemessages to get custom translatable strings
In my Django project I use Vue + vue-gettext for i18n to make translatable strings I have the following code in my my .vue files: <translate>Hello %{name}</translate> <a href="..." v-traslate>Click here</a> (using translate tags and v-translate attributes) Is there a way to configure manage.py makmessages parse this code as well ? (by default it does not look into vue files or parse this i18n code format)
