How to run django-pytest on a project which imports settings from environment variables defined in manage.py
I'm working on a Django project in which settings such as SECRET_KEY are defined in a .env file, and manage.py sets the environment variable using python-dotenv as follows: from dotenv import load_dotenv, find_dotenv if __name__ == "__main__": load_dotenv(find_dotenv()) # usual manage.py code Then settings.py simply defines module-level settings from environment variables, for example, SECRET_KEY = os.environ['SECRET_KEY'] I'm now in the process of switching to pytest-django for unit testing. The problem, however, is that without running python manage.py first, the environment variables don't get set, so I end up with E KeyError: 'SECRET_KEY' The way I'm now thinking of working around this is to define a custom action to register with manage.py to run pytest (following https://docs.djangoproject.com/en/2.0/howto/custom-management-commands/). This seems a bit like using a sledgehammer to crack a nut, though. Any suggestions of more elegant ways to go about this problem? -

Django request.GET Recieves Dict of Arrays
I am using Django's Restful Api 'APIView'. When I do a request.GET I get the following: {'param_A': ['things_A'], 'param_B': ['things_B']} However, I was wondering if there was a way to get the parameters not in form of an array so like this: {'param_A': 'things_A', 'param_B': 'things_B'} -
How to limit the selectable date range on UI for Crispy Form - forms.DateField?
In my form declaration, I have this field: effective_date = forms.DateField(required=False, label='Effective Date', widget=forms.TextInput(attrs={'class': 'datepicker'})) I want to limit the selectable date range on the datepicker to be [today - 30, today]. Is there a way to do it in Django crispy form? I'm using Django 1.9 with crispy form. FYI I tried the SelectDateWidget but it is not the UI I want. I'm looking for a component which can render this UI and support date range restriction: -

Why and how do params in annotate affect each other?
I've been reading https://docs.djangoproject.com/en/1.11/topics/db/aggregation/ a lot, but I'm still missing something. Using Django 1.11, say I have the following models: class School(models.Model): pass class Classroom(models.Model): school = models.ForeignKey(School, on_delete=models.PROTECT) active = models.BooleanField() busy = models.BooleanField() class Chalkboard(models.Model): classroom = models.ForeignKey(Classroom, on_delete=models.PROTECT) class Whiteboard(models.Model): classroom = models.ForeignKey(Classroom, on_delete=models.PROTECT) And I create a school, with a classroom, which has 2 whiteboards and 2 chalkboards: s = School() s.save() c = Classroom(school=s, active=True, busy=False) c.save() Chalkboard(classroom=c).save() Chalkboard(classroom=c).save() Whiteboard(classroom=c).save() Whiteboard(classroom=c).save() Whiteboard(classroom=c).save() I want a summary of how many chalkboards there are at each school that is active but not busy. q = School.objects.filter( Q(classroom__active=True) & Q(classroom__busy=False) ).annotate( chalkboard_count=Count('classroom__chalkboard'), ) q[0].chalkboard_count 2 # as expected Now I want to know about chalkboards and whiteboards. q = School.objects.filter( Q(classroom__active=True) & Q(classroom__busy=False) ).annotate( chalkboard_count=Count('classroom__chalkboard'), whiteboard_count=Count('classroom__whiteboard'), # added this line ) q[0].chalkboard_count 6 # expected 2 q[0].whiteboard_count 6 # expected 3 If I chain the calls to annotate, I get the same result. q = School.objects.filter( Q(classroom__active=True) & Q(classroom__busy=False) ).annotate( chalkboard_count=Count('classroom__chalkboard') ).annotate( whiteboard_count=Count('classroom__whiteboard') ) q[0].chalkboard_count 6 # expected 2 q[0].whiteboard_count 6 # expected 3 All the while, the counts are what I expect Chalkboard.objects.count() 2 Whiteboard.objects.count() 3 What am I doing wrong here? -
Showing child properties on main database object in Django admin site
i am asking a similar question to this here but the solutions presented in that question did not make sense my situation. Basically i have 3 different models set up. One for portfolio which holds a number of transactions, one for coins which is just a model holding some info on a coin and a transaction model which holds info on a purchase of a coin and is tied to a portfolio: models.py from django.db import models class Portfolio(models.Model): name = models.CharField(max_length=250) @property def coins(self): return Transaction.objects.filter(portfolio=self) def __str__(self): return self.name class Coin(models.Model): name = models.CharField(max_length=100) symbol = models.CharField(max_length=5) price = models.DecimalField(max_digits=20, decimal_places=9) info = models.TextField() website = models.TextField() rank = models.IntegerField() def __str__(self): return self.name + " - " + self.symbol class Transaction(models.Model): portfolio = models.ForeignKey(Portfolio, on_delete=models.CASCADE) coin = models.ForeignKey(Coin, on_delete=models.PROTECT) purchaseDate = models.DateTimeField() soldDate = models.DateTimeField(default=None, null=True, blank=True) amount = models.DecimalField(max_digits=20, decimal_places=3) price = models.DecimalField(max_digits=20, decimal_places=9) Now my problem is I want to see a list of transactions when I click on a portfolio however currently all I see is this: without the coins property showing up and inside it its transactions. I also can see the individual coin and transaction objects but that aren't all tied together … -
How do you save a single space (" ") in a field in a django Model?
My model definition looks like this: class MyModel(models.Model): tag_separator = models.CharField(max_length=1, null=True, blank=True) The tag_separator is a single character, and it can be a single space: " ". I need to select null=True in order to get it to work, but when I POST data through my REST API, it saves the tag_separator as an empty string: "tag_separator": "". Is there a simple way to stop django from assuming that my single space string is an empty string? I am using: Django==1.11 and djangorestframework==3.7.7 -
Django 1.10 media (FileField) 404
My first question ever, so go easy. I'll give as much detail as possible. My setup django 1.10 (I know, I need to upgrade) python 3.5.[something] postgres DB gunicorn nginx The problem and what I've tried The problem is that I pulled a recent commit that was working fine locally and suddenly none of a model's images, which previously rendered fine, are working - I'm getting 404s for all of them. I've tried the following: Checking out previous commits Restarting gunicorn (sudo systemctl restart gunicorn) Restarting nginx Restarting postgresql Using python manage.py shell to access objects and check that they're still associating with a URL to the file My code works when run locally - none of the uploaded images/files are causing 404s. As with my production environment, the logos folder sits in the main directory of my project, rather than being appended to a media folder (which other answers and the django docs suggested would be the case - this could be a red herring though). My browser console shows the 404s and that it's trying to fetch from <domain.com>/media/logos/<filename>, even though they're stored (I've checked the file structure) in <project_folder>/logos/<filename> (i.e. without the media folder), but this was … -

Django: path doesn't find the right primary key in url path
I'm using django2 and I get an error when I access this url: http://127.0.0.1:8000/hotes/12/access/7/update I get an error 404 "None access object was found" To make a long story short: I want to update an object linked to another. To do so, I have to send through the link, both primary keys (12 and 7 in the url). Also, I use the generic view "UpdateView" given by Django. This is the path concerned in my project.urls: urlpatterns = [ path('hotes/<int:pk>/access/<int:access_pk>/update',views.AccessUpdateView.as_view(), name='access_update'), ] I want the second primary key to be used in my view "AccessUpdateView". This is a part of my models.py: class Host(models.Model): name = models.CharField(max_length=30, unique=True) usage = models.CharField(max_length=30, blank=True) function = models.CharField(max_length=30, blank=True) production = models.NullBooleanField(blank=True, null=True) place = models.CharField(max_length=30, blank=True) type = models.CharField(max_length=30, blank=True) processor = models.DecimalField(max_digits=3, decimal_places=2, null=True, blank=True) storage = models.CharField(max_length=10, blank=True) memory = models.CharField(max_length=10, blank=True) dns_inner = models.CharField(max_length=50, blank=True) dns_extern = models.CharField(max_length=50, blank=True) os = models.ForeignKey(Os, null=True, related_name='hosts', on_delete=models.SET_NULL, blank=True) class Access(models.Model): service = models.CharField(max_length=20) client_access = models.NullBooleanField(blank=True, null=True) ip = models.GenericIPAddressField() login = models.CharField(max_length=30, blank=True) password = models.CharField(max_length=50, blank=True) host = models.ForeignKey(Host, related_name='access', on_delete=models.CASCADE) As you can see on host can have multiple access but an access in linked to only one … -

nginx doesn't serve static files
I've configured a conda virtual environment for Python 3.6 under OS X and installed everything necessary to test the deployment: Nginx, django, gunicorn, celery. My app runs perfectly well on a Django test server, so I've tried serving it via Nginx. The site works (all pages open and submissions carry on), but Nginx serves no static files.

Update User Model Without Entering Password
I am trying to create a page where users can edit their first_name, last_name or email that is stored in the User model. However whenever try to do so, the page refreshes and asks for the password. Is there anyway to make these changes without entering the password. This is what my original UserFrom looks like (this is what users fill out when they register): class UserForm(forms.ModelForm): email = forms.EmailField(required=True) password = forms.CharField(widget=forms.PasswordInput()) confirm_password = forms.CharField(widget=forms.PasswordInput()) class Meta: model = User fields = ('username', 'first_name', 'last_name', 'email', 'password') # Make sure passwords match: def clean(self): cleaned_data = super(UserForm, self).clean() password = cleaned_data.get("password") confirm_password = cleaned_data.get("confirm_password") if password != confirm_password: raise forms.ValidationError("Password do not match") And here is the form users can use to edit the User model once signed up: class EditUserForm(forms.ModelForm): class Meta: model = User fields = ('username', 'first_name', 'last_name', 'email') exclude = ('password',) and the correlating views.py: if request.method == 'POST': user_form = UserForm(data=request.POST, instance=request.user) user_form.fields['username'].widget.attrs['readonly'] = True if user_form.is_valid(): user_form.save() return HttpResponseRedirect('/account-settings/') else: user_form = EditUserForm(instance=request.user) user_form.fields['username'].widget.attrs['readonly'] = True context_dict['user_form'] = user_form Any idea on how I can have users edit the User model without entering a password? -
MultiValueDictKeyError on sending data using AJAX to Django 2

How do you "skip" the Django Middleware when using the requests library or urllib3?
I have a Django REST Framework and I am trying to pull json data from it to be used for the different projects I have in my Django application. I have middleware that hijacks urls with HttpRequest.urlconf = 'app.urls' so I don't have to use my base urls.py. Whenever I try to use requests.get("url"), my middleware picks it up and tries to redirect my original path to the api page instead of pulling the json data. Is there a way I can tell my custom Middleware to not run or is there a completely better way to do this? -

Editing a field belonging to a through table in a formset
I have two models that have a many to many relationship via a custom through table. Foo(models.Model): ... models.ManyToManyField('Bar', through='Foo_Bar', related_name='foo_bar') Bar(models.Model): ... Foo_Bar(models.Model) foo = models.ForeignKey(Foo, related_name='foobar') bar = models.ForeignKey(Bar, related_name='foobar') foobar_relationship = models.CharField() I have created a modelformset for the model Foo allowing users to edit all records of Foo belonging to a specific instance of Bar via, FooBarFormSet = modelformset_factory(Foo, form=FooForm) foobar_formset = FooBarFormSet(queryset=Foo.objects.filter(foobar__BAR_ID=id)) What I would like is to have the users be able to edit the field foobar_relationship at the same time. I am not really sure how to achieve this. I can add foobar_relationship as an input no problem, I simply add a charfield to the form used to create my formset, and then I save the values when I set the relationships. The problem is that once a value is stored I don't know how to populatethe forms in my formset during a GET request. -
A wrong id is assigned to each new object being created in Django
I deleted some objects belonging to one of my models in Django. Now when I create a new object, a wrong id is assigned to this object. This id is not successive. How can I address this problem?
