Django rest framework TokenAuthentication custom `obtain_auth_token` view not authenticating user
Here is my situation: I am using the django rest framework with TokenAuthentication. Everything works as expected, except the login call, where the client sends credentials to authenticate, and receives the token.key value associated with the authenticating user. Every call to login a user returns status=400 content='{"non_field_errors":["Unable to log in with provided credentials."]}' This indicates that the call to django.conf.auth.authenticate() in the TokenAuthentication serializer returned None rather than a valid user. Pertinent details: I made a slight modification to the built-in ObtainAuthToken class, and the AuthTokenSerializer class to facilitate logging users in with email + password rather than username + password. I also changed the way User objects are created, so that passwords are not passed back to the client. I know it's a hashed value, and will be using SSL, but I still find it unnecessary. I suspect I am doing something wrong in the second modification, as I'm fairly certain the thing that isn't working the way I expect it to is the call to authenticate() in the AuthTokenSerializer. Any help would be greatly appreciated!! Here are the relevant files: Abbreviated settings.py INSTALLED_APPS = [ # included middleware 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', # extra middleware 'rest_framework', … -
Triggering 'chosen:updated' on Django Admin popup close
I'm using the Django Admin portal as my primary methodology for toying with models in the database for my application and I prefer using the Chosen Select plugin to represent the select elements on the page. By default, the Django Admin pages are configured to trigger select elements to update their options if you modify them via the change-related, add-related, or delete-related buttons next to the appropriate fields. However, this doesn't seem to trigger the change event for the select element... I have the following code in a custom JavaScript file tied to the admin pages: $(document).ready(function() { options = { no_results_text: "Entity not found...", placeholder_text_multiple: "Choose entities...", search_contains: true } $('select').chosen(options).change(function () { $(this).trigger('chosen:updated'); }); }); I know that this code does its job because the use of $('#select').change() in the browser's console will update the Chosen Select element accordingly, but this event isn't fired when the Admin popup window is closed and the select element's value is changed... In short, I need to know what what event is triggered when the select element's options are changed so I can update the Chosen Select box as well. I could in theory have an event fire when the button that's … -
How do I resolve access denied aws s3 files?
Im trying to make files on my s3 bucket (CSS JS files) accessible to a Django application running in heroku. I think I have the settings.py configured correctly. However when I try to make changes to permissions in the S3 bucket i get access denied. I added cors and bucket policy is set to public. Ultimately when I load the application from heroku Im getting 403 errors when trying to access the static files. Bucket policy: { "Version": "2012-10-17", "Statement": [ { "Sid": "AddPerm", "Effect": "Allow", "Principal": { "AWS": "*" }, "Action": "s3:*", "Resource": "arn:aws:s3:::NameOfBucket/*" } ] } CORs configuration: <?xml version="1.0" encoding="UTF-8"?> <CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/"> <CORSRule> <AllowedOrigin>*</AllowedOrigin> <AllowedMethod>GET</AllowedMethod> <MaxAgeSeconds>3000</MaxAgeSeconds> <AllowedHeader>Authorization</AllowedHeader> </CORSRule> </CORSConfiguration> How can I get the permissions to make changes in the s3 bucket please? -
Start Django config app only once when using multiple Gunicorn workers
I'm using : python 3.6 django==2.1.1 gunicorn==19.9.0 i have done the following: created a django project called api created an apiapp (an app in my project) and i have this code in api_app's apps.py : from django.apps import AppConfig from api import settings class Apiapp(AppConfig): name = 'apiapp' verbose_name = "random_name" def ready(self): self.job() @classmethod def job(cls): ### doing whatever here for example : print(settings.SHARED_VARIABLE) and the following in api_app's __init__.py: import os default_app_config = 'linkedin.apps.LinkedinConfig' i'm creating an API so i am required to use multiple workers when deploying: gunicorn api.wsgi -w 10 now, my issue is that the function job which is called when the server is started, is getting called 10 times because i'm using 10 gunicorn workers, i would like to call it only once another thing that i would like to do is to have the settings.SHARED_VARIABLE variable, shared between the different workers. this variable will be updated only by the worker that will launch the app.py on server start. Thank you ! -
How do I resolve invalid literal for int() with base 10: 'arbitrary_username'?
I've read what I could manage to dig up in terms of UpdateView, test_func and get_object within the docs and on SO not to mention various articles. It has now been three days of grinding along and I'm out of ideas. Can someone explain test_func() to me like I'm five, please? :) The views.py is: class GalleryUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView): # form_class = GalleryUpdateForm model = Gallery slug_field = 'owner' slug_url_kwarg = 'username' success_url = '/' def form_valid(self, form): form.instance.owner = self.request.user return super().form_valid(form) def test_func(self): obj = self.get_object() if self.request.user == obj.owner: return True else: return False The models.py is: class Gallery(models.Model): class Meta: verbose_name = 'gallery' verbose_name_plural = 'galleries' owner = models.ForeignKey(User, on_delete=models.CASCADE) extra_img = models.ImageField(default='default.jpg', upload_to='images') def __str__(self): return self.owner.username def get_absolute_url(self): return reverse('account:view-profile', args=[str(self.owner.username)]) def save() Finally, the urls.py: urlpatterns = [ ... ... path('update-gallery/<str:username>/', GalleryUpdateView.as_view(), name='update-gallery'), ] I had it running without the fancy UserPassesTestMixin in a more simplified setup; it did what it was supposed to, but as soon as I try to implement specific users, I'm in trouble. I've tried a whole slew of permutations of the test_func variables, and I believe this is the closest I've come to an actual resolution. Here I … -
Django: from 2 functions to 1 class
I've 2 functions: 1 for creating the order, 1 for just for displaying records of a model. These are: cart_charge (works with request.POST) and cart_detail However, I also have 2 models that need to interact with them and need to be called between them. But since there are called inside the 2 different functions I wondering if it is ok to do so. How can I convert the 2 functions into 1 single class: This one creates the Order as order_details. order_details needs to be called in cart_details for creating the OrderItem. @csrf_exempt def cart_charge(request): culqipy.public_key = settings.CULQI_PUBLISHABLE_KEY culqipy.secret_key = settings.CULQI_SECRET_KEY amount = request.POST.get('amount') currency_code = request.POST.get('currency_code') email = request.POST.get('email') source_id = request.POST.get('source_id') last_four = request.POST.get('last_four') dir_charge = {"amount": int(amount), "currency_code": currency_code, "email": email, "source_id": source_id} charge = culqipy.Charge.create(dir_charge) transaction_amount = int(charge['amount'])/100 #Necesario dividir entre 100 para obtener el monto real, #Esto debido a cómo Culqi recibe los datos de los pagos transaction = Transactions.objects.create( charge_id = charge['id'], last_four = last_four, email = email, amount = transaction_amount, ) try: order_details = Order.objects.create( token = source_id, #nombre del token total = transaction_amount, emailAddress = email, billingName = billingName, billingAddress1= billingAddress1, billingCity= billingCity, billingPostCode = billingPostCode, billingCountry= billingCountry, shippingName= shippingName, shippingAddress1= shippingAddress1, … -
How can I know Django Models dependencies that avoid to delete an instance due to models.PROTECT setting
I have a Django model Reservation that is the root of a very complex structure, because it is the base for other models for different parts of the system, like reservation itinerary, operations, quotations, rates, etc., that have their own dependencies also. Some times we requiere to delete a reservation record, but we are unable due to dependencies. The problem is that the dependencies tree is so complex, that it is very time consuming to explore all the possible dependencies. Is there any way to know all the objects that reference a model object through foreign keys, so they can be reported to users so they can take of them and make the required changes to be able to delete the object? -
Is it possible to make free mezzanine cms themes (Moderna, Flat, Nova & Solid) editable in admin?
I found some Django Mezzanine CMS themes (Moderna, Flat, Nova & Solid) on Github. I managed to use these in Mezzanine CMS. But these themes are implemented as 'HOMEPAGE AS STATIC TEMPLATE' in urls.py. I tried to change this according to the instructions (among others in the comment of urls.py and the documentation) to 'HOMEPAGE AS AN EDITABLE PAGE IN THE PAGE TREE'. This was only partly succesful. In the end I didn't get any errors but I only saw the outline of the page not the content. Has anyone exerience with this? Can this be done or are the themes simply to complicated to change them into editable pages in the admin? KR Berweb -

Django AAdmin: Multiple editable entries in one column in ChangeList View
with this model: class MyModel(models.Model): a = models.BooleanField(default=False) b = models.BooleanField(default=False) c = models.BooleanField(default=False) and this admin definition: class MyModelAdmin(admin.ModelAdmin): list_display = ( 'a', 'b', 'c', ) list_editable = ( 'a', 'b', 'c', ) I have a, b and c in one column each. Is there a way to place a, b and c in the same column? I tried this: class MyModel(models.Model): a = models.BooleanField(default=False) b = models.BooleanField(default=False) c = models.BooleanField(default=False) def all(self): return self.a, self.b, self.c class MyModelAdmin(admin.ModelAdmin): list_display = ( 'all', ) list_editable = ( 'all', ) and get following error: "The value of 'list_editable[0]' refers to 'all', which is not an attribute of 'app.MyModel'."

Django Dynamic formset: correct usage with inline formsets?
I am using Django Formsets to make invoices (need to add items, people, materials etc.). To be able to add and delete formsets, I am using Django Dynamic Formset. However, this plugin seems to be no longer maintained and while it seems to work fine for modelformsets, the problem arises with inline formsets. I am using this logic to select the number of extra forms I need for the view(where you can modify your invoice) costi_offerta_inline = forms.inlineformset_factory(offerta_impianti, offerta_impianti_costi, form=offerta_impianti_costi_form, extra=0) if (offerta_impianti_costi.objects.filter(offerta_ref=instance).count() > 0) else forms.inlineformset_factory(offerta_impianti, offerta_impianti_costi, form=offerta_impianti_costi_form, extra=1) Problem is that doing this(it's probably not the reason, but you never know) the formsets act weird. If I add a new form, it works fine. Total Forms updates adding plus one and form is displayed correctly. But when I try to remove one, Total Forms doesn't decrement and I'm left with an extra form that blocks all validation from happening. Can someone help me? -

Django- Using django_filter and Django Forms together
So i am trying to figure out if there is a way to filter results of the database with django_filter and then (on the same url) use the filtered results in a form to edit them. I have a FilterSet which works just fine and the results are plain text with a edit button that gets me to another url where I can edit the results in a Form. However I would like to edit the results on the same webpage to edit them right then and there. SO basically just combining the filtering and the editing on one page. Is there a way to combine both templates? Here is some of my code. my filters.py class CSVFilter(django_filters.FilterSet): class Meta: model = Excel7 fields = {'test1' : ['icontains'], 'test2' : ['icontains'], 'test3' : ['icontains'], 'test4' : ['icontains']} my forms.py class DocumentForm(forms.ModelForm): gebaeudebereich = forms.CharField(required=False) gebaeudenummer = forms.CharField(required=False) ebene = forms.CharField(required=False) raum = forms.CharField(required=False) dose = forms.CharField(required=False) switch_ip = forms.CharField(required=False) switch_port = forms.CharField(required=False) datum = forms.CharField(required=False) akteur = forms.CharField(required=False) class Meta: model = Excel7 fields = ('gebaeudebereich', 'gebaeudenummer', 'ebene', 'raum', dose', 'switch_ip', 'switch_port', 'datum', 'akteur', ) The view that handles the filtering def filter_location(request): user_list = Excel7.objects.values() user_filter = CSVFilter(request.GET, queryset=user_list) … -
