Fill requirements.txt from PyCharm virtual environment
I am trying to fill a requirements.txt for my PyCharm Django project that has a virtual environment.

A bug in 'Request and response objects' documentation?
In the first section of Request and response objects | Django ,documentation | Django It says: When a page is requested, Django creates an HttpRequest object that contains metadata about the request. Then Django loads the appropriate view, passing the HttpRequest as the first argument to the view function. Each view is responsible for returning an HttpResponse object. Amongst the second sentence, 'the HttpRequest' in passing the HttpRequest as the first argument, its link refers to 'class HttpRequest[source]¶'. It is obvious that it's the object not the class are passed as the first argument. However, the HttpRequest is used instead of the object or the HttpRequest object. If a Bug, it' easy to debug, whereas I checked multiple versions of documentation, they stay the same. If not a Bug, how to explain it? -

How do I thoroughly delete an old image file when a user updates the form's imagefield?
I have two modelforms--one includes a standard ImageField and the other is an inlineformset of ImageFields. The normal standard ImageField renders on the page with the option for "Clear[ing]" while the inlineformset ImageFields render with an optional "Delete" tickbox. Either Clear or Delete will remove the image from the User's profile, but the actual image file will remain in storage, as well as the URL to the image. I am trying to remove all associations to the image once the User updates his Profile form by "clearing" or "deleting" the image. I found FieldFile.delete which I believe just requires me to call .delete() on the instance, but I'm not sure how to conditionally check whether the user is updating the form with the "delete" box or "clear" box ticked. Here are the two models containing the image fields: class Profile(models.Model): profile_photo = models.ImageField( upload_to=profile_photo_upload_loc, null=True, blank=True, verbose_name='Profile Image', ) class CredentialImage(models.Model): profile = models.ForeignKey(Profile, default=None, related_name='credentialimage') image = models.ImageField( upload_to=credential_photo_upload_loc, null=True, verbose_name='Image Credentials', ) The ModelForms: class ProfileUpdateForm(ModelForm): class Meta: model = Profile fields = [ "profile_photo", ] class CredentialImageForm(ModelForm): image = ImageField(required=False, widget=FileInput) class Meta: model = CredentialImage fields = ['image', ] CredentialImageFormSet = inlineformset_factory(Profile, CredentialImage, fields=('image', ), extra=2) … -
Request and response objects

Django allauth facebook login failed to redirect back when in an in-app-browser
Problem When in an in-app-browser, like Google Hangout, Telegram or LINE messenger, the user won't be redirected back to my website after a success login through facebook login dialog.

Type object error while trying to inherit a form.Models base class with UserCreationForm base class
I was trying to inherit a form class object which uses forms.ModelForm into a different form class object which inherits from UserCreationForm. I undertand that when form models are been inherited, only one Meta supersedes. However, I still gave it a shot as that's the only way to achieve the business logic I am trying to arrive at. The codes below, pls kindly look through and suggest a work around: class AddressMixin(forms.ModelForm): class Meta: model = Subscriber fields = ['address_one', 'address_two', 'city', 'province'] widgets = { 'address_one':forms.TextInput(attrs={'class':'form-control'}), 'address_two':forms.TextInput(attrs={'class':'form-control'}), 'city': forms.TextInput(attrs={'class':'form-control'}), 'province': forms.TextInput(attrs={'class':'form-control'}), } class SubscriberForm(AddressMixin,UserCreationForm): first_name = forms.CharField(required=True, widget=forms.TextInput(attrs={'class':'form-control'})) last_name = forms.CharField(required=True, widget=forms.TextInput(attrs={'class':'form-control'})) email = forms.EmailField(required=True, widget=forms.TextInput(attrs={'class':'form-control'})) username = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control'})) password1 = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control', 'type':'password'})) password2 = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control', 'type':'password'})) Heres the error I am getting, AttributeError at /subscribe/signup/ type object 'Subscriber' has no attribute 'USERNAME_FIELD' Again, I understand the error is refering to the subscriber model not having username as an attribute, because the AddresMixin Meta supersedes. However the AddressMixin model contains some business logic methods that needs to be submit during registeration, hence, it needs to pass through the same form. Any advice will help, while I keep trying to figure it out. -
Not redirecting after requests.post django
I'm currently using django rest framework api and I have a form to enter some api information in. I'd like to redirect after I submit my form while still POSTing the data to the API url using the requests library. However the HttpResponseRedirect isn't triggering a redirect for some reason Here is my views.py from rest_frame.requests import reverse import requests def entry_new(request): if request.method == 'POST': form = EntryForm(request.POST) if form.is_valid(): url = reverse("entry-list",request=request) r = requests.post(url, data=request.POST, cookies=request.COOKIES) ## THIS IS WHAT ISN'T FIRING - it goes back to entry_new's URL HttpResponseRedirect(reverse('index2')) else: form = EntryForm return render(request, 'entry_new.html', {'form': form}) class entry_ViewSet(viewsets.ModelViewSet): queryset = Entry.objects.all() serializer_class= EntrySerializer permission_classes = (permissions.IsAuthenticatedOrReadOnly,) def perform_create(self, serializer): serializer.partial = True serializer.save(created_by=self.request.user, modified_by=self.request.user, modified_date=datetime.now()) my serializers.py class EntrySerializer(serializers.ModelSerializer): created_by = serializers.ReadOnlyField(source='created_by.username') modified_by = serializers.ReadOnlyField(source='modified_by.username') class Meta: model = Entry fields = '__all__' my urls.py router = DefaultRouter() router.register(r'entry', views.entry_ViewSet, base_name="entry") urlpatterns = [ url(r'^index2/$',views.index_two, name='index2'), url(r'^cat_new/$', views.category_new, name='cat_new'), url(r'^entry_new/$', views.entry_new, name='entry_new'), url(r'^api/', include(router.urls)), ] -
Django Media Files Not Uploading to S3 Amazon from main site
I'm stuck and confused trying to get this work. I'm running Django on Heroku, using Python 2.7.14 using Django-Storages 1.6.5 trying to upload to Amazon S3. Deploying my site, I can use the Admin site in Django and upload a file to S3 with no problem. Using the non-admin site, I try to upload a media file and it doens't work. The file upload field is is denied by Amazon. Static works with no issue. Why would the Admin site be able to upload media files and the main site not be able to, when they use the same models? -
Serialize queryset based on individual field values using Django Rest Framework
Goal If an object has revealed=true it serializes into: { "id":1, "info":"top secret info", "revealed":true } If an object has revealed=false it omits the info field: { "id":2, "revealed":false } So for a queryset of objects: [ { "id":1, "info":"top secret info 1", "revealed":true }, { "id":2, "revealed":false }, { "id":3, "info":"top secret info 3", "revealed":true } ] Is it possible to achieve this inside of a Django Rest Framework Model Serializer class? class InfoSerializer(serializers.ModelSerializer): class Meta: model = Info fields = ('id', 'info', 'revealed') Background The DRF docs discuss some advanced serializer usage, and this other post dives into an example. However it doesn't seem to cover this particular issue. Ideas A hacky solution would be to iterate over the serialized data afterwards, and remove the info field for every object that has revealed=false. However 1) it involves an extra loop and 2) would need to be implemented everywhere the data is serialized. -
Passing HTML Template Multiple Checkboxes to a new Django form

Django form with inputs populated from database
I have a simple Django model structure with Products and Orders, linked by an intermediary table that determines the quantity of each product within a given order: models.py: class Product(models.Model): name = models.CharField() class Order(models.Model): id = models.IntegerField() products = models.ManyToManyField(Product, through='OrderProduct') class OrderProduct(models.Model): order=models.ForeignKey(Order, on_delete=models.CASCADE) product = models.ForeignKey(Product, on_delete=models.CASCADE) quantity = models.PositiveSmallIntegerField() I'd like to design a form in my forms.py file that 1) pulls a list of every product in the database; 2) gives the user the option to adjust the quantity of each product ordered (e.g., in a CharField input), and 3) creates new Order and OrderProduct objects that store a record of the quantity of each Product ordered by the user. However, I can't figure out a good way to create a form that will automatically pull all Products from the database and add fields to represent the quantity ordered of the given Product. Ideally the result would look something like this, but coded automatically: forms.py: class OrderForm(forms.Form): product_1_quantity = forms.IntegerField() product_2_quantity = forms.IntegerField() product_3_quantity = forms.IntegerField() ....etc., for each product. What's the best way to do this? Does it involve a 'for' loop that creates a new field for each product found in the database? -

ValidationError on related model created in inline admin causes 500
I'm creating a one-to-one model to extend the functionality of an existing model type, but I want it to only allow creating the extension model in certain cases. I enforce this constraint by throwing a ValidationError in the full_clean on the new Extended model. This works great when I create Extended models using Extended's ModelAdmin directly (it highlights the a field if it's the wrong type), but when I use StackedInline to inline Extended creation in As ModelAdmin, and A is the wrong type, the form fails to catch the ValidationError and I get the message A server error occurred. Please contact the administrator. This is how I have the models set up: # models.py from django.db import models class A(models.Model): type = models.IntegerField(...) class Extended(models.Model) a = models.OneToOneField(A) def clean_fields(self, **kwargs): if self.a.type != 3: raise ValidationError({'a': ["a must be of type 3"]}) def save(self, *args, **kwargs): self.full_clean() super(Extended, self).save(*args, **kwargs) # admin.py from django.contrib import admin class ExtendedInline(admin.StackedInline): model = Extended @admin.register(A) class AAdmin(admin.ModelAdmin): inlines = (ExtendedInline,) The full traceback: Traceback (most recent call last): File "/usr/local/lib/python2.7/wsgiref/handlers.py", line 85, in run self.result = application(self.environ, self.start_response) File "/usr/local/lib/python2.7/site-packages/django/contrib/staticfiles/handlers.py", line 63, in __call__ return self.application(environ, start_response) File "/usr/local/lib/python2.7/site-packages/whitenoise/base.py", line 66, … -

Django: Changed AUTH_USER_MODEL and now getting IntegryErrors when updating other model that references it
I'm using the django-hitcount app on my web app to count hits on some pages, and the hit model references the AUTH_USER_MODEL on a foreign key (the settings variable that defines which model is used as user model). When I started, my webapp wasn't using login, so django-hitcount defaulted to the default user model from Django when I ran the migrations. But now, I've created a custom user model, and the app is throwing integrity errors because, as far as I can tell, the hitcount app ForeignKey is still pointing to the default django user model. IntegrityError at /category/28/22 (1452, ‘Cannot add or update a child row: a foreign key constraint fails (`detdb`.`hitcount_hit`, CONSTRAINT `hitcount_hit_user_id_10387956e3370b97_fk_auth_user_id` FOREIGN KEY (`user_id`) REFERENCES `auth_user` (`id`))’) Is there any way I can update the foreign key without losing all my hit instances?
