Django: How to delete token after it is used?
In Django, I am generating tokens for account activation. Here is the actual code: 'uid': urlsafe_base64_encode(force_bytes(user.pk)), 'token': default_token_generator.make_token(user), The problem is once it is used it is still valid. Django password reset mechanism (password_reset_confirm() view) somehow invalidates the token after it is used. How can I do the same? -

Nested django form for foreignkey model
I have two models that look something like class Address(models.Model): line1 = models.CharField(max_length=128, help_text="Address Line 1") city = models.CharField(max_length=128) state = USStateField() zipcode = USZipCodeField() class Company(models.Model): name = models.CharField(max_length=100) address = models.ForeignKey('Address', on_delete=models.PROTECT) The actual classes have many more fields and so I would like to automatically generate forms for creating a new company, and so I am using Django's ModelForm. Howevere, I would like to let the user choose between choosing an existing address or creating a new one all in one form. Is there a way to nest a AddressModelForm inside of a ComanyModelForm? class CreateAddressForm(forms.ModelForm): class Meta: model = Address exclude = [] class CreateCompanyForm(forms.ModelForm): class Meta: model = Company exclude = [] # Use nested form for address # custom widget maybe? How should I approach this problem? Thanks! -

Creating an abstract model for
I deleted my previous question, since it was terribly worded and my non-working examples were just confusing. I have a series of models, such as Vehicle, Computer, Chair, and whatnot. My goal is to be able to attach an arbitrary number of images to each of them. That's my question: what's the best design pattern to achieve this? What I've tried so far is to create an abstract model, AttachedImage. I then inherit from this model, and create more specific models, like VehicleImage, ComputerImage, or ChairImage. But this doesn't feel like the right way to pursue this. -

Django model inheritance with arguments
I'm trying to define a base, abstract model for "attached images", that I can then hook up to any other model with a foreign key relation to it. My idea is to use an argument that defines which Model will the AttachedImage model be hooked up to through a ForeignKey relation. I have my abstract model defined like so: class AttachedImage(models.Model): parent_object = None uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) author = models.ForeignKey(User, on_delete=models.CASCADE) image = models.ImageField(upload_to=image_path) # TO FIX: añadir la ruta is_default = models.BooleanField(default=False) class Meta: abstract = True def __init__(self, parent_model): super().__init__(self) self.parent_object = models.ForeignKey(parent_model, on_delete=models.CASCADE) And then I try to inherit from it like this: class VehicleImage(AttachedImage(Vehicle)): pass But when I try to run my migrations, I get this error: class VehicleImage(AttachedImage(Vehicle)): TypeError: __init__() takes 2 positional arguments but 4 were given First off, why am I getting this error? And second, and much more important: is this the right pattern to achieve my goal? -

Django: Multiple values in Radio Select Form
I've got a radio select form that displays addresses that the user has saved. Currently, when the user visits the "select address" template, they are only shown the 'street' field for each address that they've saved. This is controlled by the "return self.address" line below as I've established through testing. I'd like user to see the street, city, and state of each of the addresses that he/she has saved. From the list, they'll select the radio button next to the address that they'd like to ship to. models.py class Order(models.Model): user = models.ForeignKey(UserCheckout, null=True, on_delete=models.CASCADE) billing_address = models.ForeignKey(UserAddress, related_name='billing_address', null=True, on_delete=models.CASCADE) order_id = models.CharField(max_length=20, null=True, blank=True) class UserAddress(models.Model): street = models.CharField(max_length=120, null=True, blank=True) city = models.CharField(max_length=120) state = models.CharField(max_length=120, choices=STATE_CHOICES, null=True, blank=True) def __str__(self): return self.address I'm using a class based view. Here are some functions within that view that I belive are controlling the output within the template: def get_addresses(self, *args, **kwargs): user_check_id = self.request.session.get("user_checkout_id") user_checkout = UserCheckout.objects.get(id=user_check_id) b_address = UserAddress.objects.filter(user=user_checkout) return b_address def get_form(self, *args, **kwargs): form = super(AddressSelectFormView, self).get_form(*args, **kwargs) b_address = self.get_addresses() form.fields["billing_address"].queryset = b_address return form Within the template, I've got the following: {% csrf_token %} {{ form }} <input type='submit' value='Select' /> </form> I … -

How do you call a user defined function in views.py DJANGO
The requirement is to display the logged in username and his role in the organization in all the pages at the top right corner. The role can be identified by the permissions he is given. My approach: I thought of creating a user-defined function in views.py and call it in each and every other function. The function that I create should check the current user's permissions and based on them his role should be decided. All these details must be sent to base.html so that it will render and display the username and his role every time the page is loaded. Any suggestions on other approaches are welcomed and if my approach is entirely wrong please let me know. -
Django Session Data lost after clearing browser Data
Im using django 1.11.7 and the session objects to store data from users that are login works fine but when I clear the browser data the session object is lost, as far as I know if you use this 'django.contrib.sessions', you're setup to save the session object in the DB and im able to see Data in the Db each time someone logs in but the problem is that for some reason I cant use this data when i fetch it maybe is the way I fetch the data because the data is being saved in the DB here is how I fetch the data in the views: this is the normal way that works until I clear the browser data in_test = request.session['in_test'] then in some reading they suggest that even if the data is being saved in the db some cookies are created to match that data and they use this to some how also get the data from the session obj but same result: in_test = request.session.get('in_test') but at least there is a hint that the browser cookie is obviously missing since I cleared but the question is how to pair or directly fetch the session object … -

How to override Django admin `change_list.html` to provide formatting on the go
In Django admin, if I want to display a list of Iron and their respective formatted weights, I would have to do this. class IronAdmin(admin.ModelAdmin): model = Iron fields = ('weight_formatted',) def weight_formatted(self, object): return '{0:.2f} Kg'.format(object.weight) weight_formatted.short_description = 'Weight' I.e: 500.00 Kg The problem with this however is that I would have to write a method for every field that I want to format, making it redundant when I have 10 or more objects to format. Is there a method that I could override to "catch" these values and specify formatting before they get rendered onto the html? I.e. instead of having to write a method for each Admin class, I could just write the following and have it be formatted. class IronAdmin(admin.ModelAdmin): model = Iron fields = ('weight__kg',) def overriden_method(field): if field.name.contains('__kg'): field.value = '{0:.2f} Kg'.format(field.value) I.e: 500.00 Kg
