Django test.Client is logged in but passed as AnonymousUser in views
I have a weird problem here... I am trying to test a @login_required views so I wrote this code: from django.test import TestCase from django.test import Client from .models import SiteEcommerce from .models import Client as TestDbClient from .models import MyCustomEmailUser class DataBaseTestCase(TestCase): def __init__(self, *args, **kwargs): super(DataBaseTestCase, self).__init__(*args, **kwargs) self.c = Client() # instantiate the Django test client self.user = MyCustomEmailUser.objects.all()[0] def test_method(self): """ Test of the settings page. """ self.c.login(username=self.user.email, password=self.user.password) print self.user.is_authenticated() response = self.client.get('/main/settings/%s' % self.website.idsite) self.assertEqual(response.status_code, 200) The view called settings_view where I am printing the request.user The problem is that in the test print self.user.is_authenticated() give True BUT the request.user in the view return AnonymousUser -
Django checking for a query string
When someone clicks on my site's logout link, I want them to be redirected to the login page but I want a message to pop up saying that they were successfully logged out. However, I don't want this behaviour to occur when someone normally visits the login page. I decided to pass in a query string so now when someone hits logout they are redirected to users/login/?logout. How can I check for this in my template though? I want to do something like: {% if ______ %} *Message box appears* {% endif %} Thanks! -
Django error: "Expected table or queryset, not str"
Hi am currently building an django app by connecting with SQL server of existing data base through sql_server.pyodbc.

DetailView template not displaying it's data
within an app I have two models, named Course and Step. Every Step belongs to a Course and each Course has many steps. However, I'm having problem creating a detailview for Steps. For example when i go to the url 'http://127.0.0.1:8000/courses/1' it should display steps for course.objects.get(pk=1).

Django migration 11 million rows, need to break it down
I have a table which I am working on and it contains 11 million rows there abouts... I need to run a migration on this table but since Django trys to store it all in cache I run out of ram or disk space which ever comes first and it comes to abrupt halt. I'm curious to know if anyone has faced this issue and has come up with a solution to essentially "paginate" migrations maybe into blocks of 10-20k rows at a time? Just to give a bit of background I am using Django 1.10 and Postgres 9.4 and I want to keep this automated still if possible (which I still think it can be) Thanks Sam -
Is there a better way to create a Django REST Web Service?
I'm new to Python Django - further to my question. I create a REST Web Service but I'm totaly unhappy with my code, but i can not find ab better solution.

Retrieving attributes of currently selected objects in Django
Right now I'm trying to make an e-commerce site. My problem is that calculate the total amount the user has spent on the current purchase, my problem is that I don't know how to use the price from the current Product object, instead I'm just getting None.

How to intercept and control saving a Django POST form?
When the user is required to fill his profile, he picks a city from the Google Places Autocomplete and posts the form, in the view I extract the city Id from the Google API based on the posted text (I use the same id as pk in my db) and try to extract a city from my db. These are the models: class City(models.Model): #extracted from the Google API city_id = models.CharField(primary_key=True, max_length=150) name = models.CharField(max_length=128, blank=True) country = models.CharField(max_length=128, blank=True) class UserProfile(models.Model): user = models.OneToOneField(User, related_name='profile', primary_key=True) city = models.ForeignKey(City, blank=True, null=True) prof_pic = models.ImageField(blank=True, upload_to='profile_pictures') This is the view: def createprofile(request): if request.method =='POST': user = User.objects.get(username=request.user.username) user_form = UserForm(data=request.POST, instance=user) profile_form = UserProfileForm(data=request.POST) if user_form.is_valid() and profile_form.is_valid(): user = user_form.save() user.save() profile = profile_form.save(commit=False) profile.user = user #brings back the city search result as text searched_city = request.POST['city'] #brings back city ID from the Google API searched_city_id = population_script.get_city_json(searched_city.replace(" ", ""))['results'][0]['id'] #If it's a valid city if searched_city_id != -1: city = City.objects.get(city_id = searched_city_id) profile.city = city#this is what I want to happen! else: return HttpResponse("There's no such city, please try a different query.") if 'prof_pic' in request.FILES:#now save the profile pic profile.prof_pic = request.FILES['prof_pic'] print("PROF … -
How can I serialize / de-serialize a Django QuerySet without executing the queryset?
I noticed that if I pass a queryset to a Celery task (which, therefore, serializes it): my_awesome_task.apply_async((my_queryset,), queue='whatever') the query is executed, thus pulling all of the objects from the DB for nothing. Is there a way to avoid that and have it just serialize the un-executed QuerySet, itself, leaving the DB pummeling to the Celery task? -
Docker NGINX Proxy not Forwarding Websockets

Django - 'TypeError: expected string or bytes-like object' when clearing an uploaded image with Cloudinary
I'm using Cloudinary in my Django application to store and serve images that users upload in one view of my site. The images are getting uploaded and shown correctly; however, in my UpdateView when a user checks 'clear' to remove the previous image and then submits the form this error is shown: TypeError: expected string or bytes-like object The error page in the browser also shows these highlighted messages: ...\lib\site-packages\cloudinary\models.py in to_python return self.parse_cloudinary_resource(value) ... ...\lib\site-packages\cloudinary\models.py in parse_cloudinary_resource m = re.match(CLOUDINARY_FIELD_DB_RE, value) ... ...\AppData\Local\Programs\Python\Python36-32\lib\re.py in match return _compile(pattern, flags).match(string) These are what my model, view and form look like: models.py: class Item(models.Model): name = models.CharField(max_length=255) image1 = CloudinaryField('image', blank=True, null=True) views.py class ItemUpdateView(LoginRequiredMixin, UpdateView): model = models.Item form_class = forms.ItemForm forms.py class ItemForm(forms.ModelForm): image1 = CloudinaryFileField( required=False, options = {'crop': 'limit', 'width': 546, 'height': 1000,}) class Meta: model = models.Item fields = ("image1", "name") I think Cloudinary is still expecting something when the field's value is empty. I have looked at the docs and searched the web and I just can't figure out how to fix this. -
Using relational operators for several fields in django model filter
I have a requirement to find a unique record depending on two date fields and a char field as follows. Start Date End Date Item No. (There will be unique item numbers.) Owner ID - This is what should be retrieved from the model. Provided: Data model is implemented such a way, within the Start and End dates Item can only be possessed by one owner. Requirement: When the Item No. and a Date is given, find the owner of the item within that day. Let say given day is D1, Start day S1 and End day E1. I know this should be using filter logic as follows. But how can I refer those fields in my query? (negative scenarios will be discarded) Filter: (d1 >= s1) AND (d1 <= e1) -

Django HTML Template Cache
I have limited experience with Django but i am having an issue where I update the HTML Template file that serves an important view on our page and some users when they view the page do not get the updated view.

My question is is there a way that part of the page can be cached while others are not from within the same template? -

Django Wagtail elastic search 2.4 ascii folding
Is it possible to set ascii folding on Wagtail elasticsearch 2.4 search backend so that e.g. searching for "Nimes" returns objects with "Nîmes" indexed?

Merging models, Django 1.11
After upgrading from Django 1.8 to 1.11 I've been looking at a means of merging some records - some models have multiple entries with the same name field, for example. There's an answer here that would appear to have what I would need: https://stackoverflow.com/a/41291137/1195207 I tried it with models like this: class GeneralType(models.Model): #... domains = models.ManyToManyField(Domain, blank=True) #... class Domain(models.Model): name = models.TextField(blank=False) #... ...where Domain has various records with duplicate names. But, it fails at the point indicated: for alias_object in alias_objects: for related_object in alias_object._meta.related_objects: related_name = related_object.get_accessor_name() if related_object.field.many_to_one: #...snip... elif related_object.field.one_to_one: #...snip... elif related_object.field.many_to_many: related_name = related_name or related_object.field.name for obj in getattr(alias_object, related_name).all(): getattr(obj, related_name).remove(alias_object) # <- fails here getattr(obj, related_name).add(primary_object) The problem is apparently that 'GeneralType' object has no attribute 'generaltype_set'. Adding a related_name to GeneralType doesn't fix this - the script fails in the same manner but quoting the name I've now given it. I'm not quite sure what Django is up to here so any suggestions would be welcome. -
How to exclude certain entries from meta ordering in django?
Hi I have the following given: class Copy(CommonLibraryBaseModel): signature = models.CharField(max_length=100, blank=True, verbose_name=u'Signatur') ... class Meta: ordering = ['signature'] What I want to do now is to define a ordering along the signature (this is already done with ordering = ['signature']), but exclude all signatures that start with a certain substring. How would I do that using the Meta class? Thanks
