difficulties with Django ''follow'' other user ( RedirectView )
I have a problem with a class in my Views.py class FollowToggle(RedirectView): def get_redirect_url(self,*args,**kwargs): username = self.kwargs.get("username") userprofile = self.kwargs.get("userprofile") user = self.request.user obj = get_object_or_404(UserProfile, user=user) if user.is_authenticated(): if user in obj.follow.all(): obj.follow.remove(user) else: obj.follow.add(user) url_ = obj.get_absolute_url() return url_ I want to give an User the option to follow each other. I have this call which I want to use later in an API. (everything is set up and running) but right now all It does is following itself. so if a user is doing http://127.0.0.1:8000/profiles/testuser/follow it redirects to the last page and updated the data in the model, but the followed user is the user himself. I figured that the Problem is obj.follow.remove(user) here should 'user' be 'username' but this throws me an error (invalid literal for int() with base 10: 'testuser'). If anybody knows how to solve this please let me know. Models.py: class UserProfile(models.Model): follow = models.ManyToManyField(settings.AUTH_USER_MODEL, blank=True,default=1, related_name='follow') def get_follow_url(self): return reverse("profiles:follow-toggle", kwargs={"user": self.user}) def get_api_follow_url(self): return reverse ("profiles:follow-api-toggle", kwargs={"user": self.user}) def get_absolute_url(self): return reverse("profiles", kwargs={"username": self.user}) -

Django 1.10 - Create two formsets from single queryobject
I have Book model, which has title, and author string fields. title fields may be different, but author is always equal to joey or martin. On a single page, I want to display two formsets, BUT I don't want to create QuerySet and make DB query separately for each form. Is it possible to, get all the objects at once, and then split them into separate lists and pass them info formset? My view function: def index(request): books = Book.objects.all() # Here we will take all at once joey_books = [] martin_books = [] for book in books: # books here are evaluated - only once! if book.author == 'joey': joey_books.push(book) elif book.author == 'martin': martin_books.push(book) joey_book_formset = forms.modelformset_factory( Book, form=BookForm, fields=['title', 'author'], can_delete=True, extra=1 ) joey_book_formset = joey_book_formset(queryset=joey_books) # Exception raised martin_book_formset = forms.modelformset_factory( Book, form=BookForm, fields=['title', 'author'], can_delete=True, extra=1 ) martin_book_formset = martin_book_formset(queryset=martin_books) # Exception raised context = { 'joey_forms': joey_book_formset, 'martin_forms': martin_book_formset, } return render(request, 'myapp/index.html', context) My expectation: Two formsets would be created and there would be running just one query. Problem: Following exception is raised: AttributeError: 'list' object has no attribute 'ordered' It is probably because formsets accept only QuerySet objects. Is there any workaround … -
Django/reportlab: Save generated pdf directly to FileField in AWS s3
I am writing a Django app, for which I need to generate a PDF, using reportlab, and save it to a FileField. My problem is that my media is stored in S3, and I don't know how to save this pdf directly to S3. I am creating the pdf locally then reading it and saving to the FileField in s3, then deleting the local version, but I'm wondering if there's a better solution, where I can save the file directly to S3. here's how I generate the contract now: #temporary folder name to generate contract locally folder_name = ( '/tmp/' + '/contracts/' + gig.identifier ) mkdir_p(folder_name) address = ( folder_name + '/contract_' + lang + '.pdf' ) doc = SimpleDocTemplate( address, pagesize=A4, rightMargin=72, leftMargin=72, topMargin=120, bottomMargin=18 ) doc.build(Story, canvasmaker=LogoCanvas) local_file = open(address) pdf_file = File(local_file) contract = Contract.objects.create(lang=lang, gig=gig) contract.contract_file.save('contract_'+lang+'.pdf', pdf_file) contract.save() #remove temporary folder shutil.rmtree(folder_name) return True and the Contract model is defined like this: class Contract(models.Model): gig = models.ForeignKey(Gig, related_name='contracts') lang = models.CharField(max_length=10, default='') contract_file = models.FileField( upload_to=get_contract_path, blank=True, null=True, default=None ) -

how to manage Django urls alias redirections?
I'd like set up my urls correctly avoiding doing it like the example below since it afects my Google indexation : urls.py (wrong way) : url(r'^virtual-reality/$', views.virtualreality, name="virtual-reality"), url(r'^virtual-reality$', views.virtualreality, name="virtual-reality"), url(r'^vr/$', views.virtualreality, name="virtual-reality"), url(r'^vr$', views.virtualreality, name="virtual-reality"), As you can see I'd like vr/, vr, virtual-reality/, virtual-reality to redirect to the same page. I have more than 30 urls on my site and doing each url redirection like this is problematic since the structure grows. I do not use Apache on my Django site, so Rewriting Rules can not be made. (I'm on pythonanywhere (webserver : Gunicorn)) What's the best way to redirect all types of aliases in the same view without affecting my google search indexation and avoid to enter each url with the same view to urls.py ? -

Django multiple SQL join when no backwards relation are created (related_name='+')?
I need to execute this SQL statement (see below) using Django's ORM. I've to join 3 Django models. This is my SQL requirement: select a.attr_a, c.attr_c from table_a as a left join table_b as b on a.a_id = b.a_id and b.d_id = 1 left join table_c as c on a.a_id = c.a_id and c.d_id = 2 where b.attr_b = 'foo' and c.attr_c = 'bar' Then here are my Django models: class A(models.Model): a_id = models.AutoField(primary_key=True) attr_a = models.CharField(max_length=250) class Meta: db_table = 'table_a' class B(models.Model): b_id = models.AutoField(primary_key=True) attr_b = models.CharField(max_length=250) fk_to_a = models.ForeignKey(A, related_name='+') fk_to_d = models.ForeignKey(D, related_name='+') class Meta: db_table = 'table_b' class C(models.Model): c_id = models.AutoField(primary_key=True) attr_c = models.CharField(max_length=250) fk_to_a = models.ForeignKey(A, related_name='+') fk_to_d = models.ForeignKey(D, related_name='+') class Meta: db_table = 'table_c' class D(models.Model): d_id = models.AutoField(primary_key=True) attr_d = models.CharField(max_length=250) class Meta: db_table = 'table_d' Is there a way to resolve this with a single Django ORM query? Otherwise, could you show me how? -
Django - credentials not working for CustomUser
I'm trying to make a custom user, but there's one problem, when i get request.user, it’s an instance of User, not an instance of CustomUser, so i don’t get the extra fields and methods. I've found this, but when i'm trying to login in the django admin it won't work anymore. Here is my code: models.py class CustomUser(User): timezone = models.CharField(max_length=50, default='Europe/Bucharest') porecla = models.CharField(max_length=50, null=True) selectat = models.BooleanField(default=False) objects = UserManager() auth_backends.py - so i can use the methods of the custom user when using request.user from django.conf import settings from django.contrib.auth.backends import ModelBackend from django.core.exceptions import ImproperlyConfigured from django.apps import apps class CustomUserModelBackend(ModelBackend): def authenticate(self, username=None, password=None): try: user = self.user_class.objects.get(username=username) if user.check_password(password): return user except self.user_class.DoesNotExist: return None def get_user(self, user_id): try: return self.user_class.objects.get(pk=user_id) except self.user_class.DoesNotExist: return None @property def user_class(self): if not hasattr(self, '_user_class'): self._user_class = apps.get_model(*settings.CUSTOM_USER_MODEL.split('.', 2)) if not self._user_class: raise ImproperlyConfigured('Could not get custom user model') return self._user_class settings.py AUTHENTICATION_BACKENDS = ('football_app.auth_backends.CustomUserModelBackend', ) CUSTOM_USER_MODEL = 'football_app.CustomUser' admin.py class CustomUserAdmin(admin.ModelAdmin): list_display = ('username', 'email', 'first_name', 'last_name', 'is_staff', 'is_active', 'selectat', ) admin.site.register(CustomUser, CustomUserAdmin) -
How to remove Django`s BinaryField from memory?
I have a Django model with BinaryField: class MyData(models.Model): someData = models.CharField() data = models.BinaryField() In my app I need to iterate over the big set of rows. Of course I mark binary field as deferred: myDataList = MyData.objects().filter(...).defer('data') for myData in myDataList: doSmthWithData(myData.data) ... The result of the initial request requires small amount of memory. But while I iterate over the query set I fetch binary data from the database. Because of the size of the binary fields, memory is quickly exhausted. We can do a trick to free the memory - at the end of loop set data to None: myData = None. But in this case to modify and save entity I need to query it again from the database, otherwise binary data will be lost. Do we have any other way to delete binary data from the memory? Something like: set_defer(myData.data) -

Cant seem to retrieve info on django many to many, 'object has no attribute'

My Python web crawler loop thru a list but writes over and over in the same field in my SQL Database
I working on web crawler, which gathers brand names for my an save the name in a SQL database. Since I'm programming with python I choose Django to build my GUI, so I also use Djangos ability to connect to SQL database. Somehow when I loop thru the list of brands, in the end it's aways the last brand name wich get stored in the database. My suspicion is that I didn't understand how the auto field of my brand class is working. So I will show you, how my brand class looks like, I will not post the whole web crawler, cause it's not important how I code that one, in the end the crawler return a list, and then I will sho you the function saveBrands(), which should store the brand names in my database.

How do I upload images to a separate imageFields in Django model using Django form inside a Bootstrap modal?
I am currently creating a website using Django. I am creating a gallery page where the user can upload and display images inside 8 different squares. Each square is a different ImageField in the model. When the user clicks a square on the page a Bootstrap modal appears, containing a form that the user can use to upload an image. This works and at the moment I can upload an image to one of the squares, however, I would like to: 1) Check which image square has been clicked on the page allowing me to update the corresponding image in the database. 2) load this image into the correct image square. Code for the modal that appears when the user clicks the square, and then saves the image: <div class="modal fade" id="image-upload"> <div class="modal-dialog"> <form class="modal-content" action="#" method="POST" id="imageform" enctype='multipart/form-data'> {% csrf_token %} <div class="modal-header"> <h5 class="modal-title">Modal title</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div class="modal-body"> <p>Upload a item..</p> <div class="form-group filepicker"> <label for="{{form.image.imageid }}">Image:</label> {{ form.image }} </div> </div> <div class="modal-footer"> <button type="submit" class="save btn btn-default">Upload</button> <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button> </div> </form> </div> </div> JQuery to load the modal: <script> $(function(){ $(".img-thumbnail").click(function(eventObject){ $('#image-upload').modal() alert(imagesquare) }) … -

TestCase - Exception not raised in with statement when mocking __enter__
I'm trying to test a Python method containing a with statement. The code inside the with statement can raise an RuntimeError. The test I'm talking about tests if the RuntimeError is raised. The __enter__ and __exit__ methods are heavy (typically open and close SSH connections), and I mock them when testing. Here is a simplified definition of the method I want to test: # client.py class Client(): def method_to_test(): with self: raise RuntimeError() For clarification purpose, I omitted the definition of __enter__ and __exit__, and removed all the code in method_to_test which was not involved in the current issue. To test this method, I mock __enter__ and __exit__, and check if RuntimeError is raised: # tests.py from django.test import TestCase import mock from .client import Client class ClientTestCase(TestCase): @mock.patch('mymodule.client.Client.__enter__') @mock.patch('mymodule.client.Client.__exit__') def test_method_raises_Runtime(self, mock_exit, mock_enter): mock_enter.return_value = None client = Client() with self.assertRaises(RuntimeError): client.method_to_test() This test fails with: AssertionError: RuntimeError not raised If I do not mock __enter__, the RuntimeError is raised. Why does mocking __enter__ makes this test fail? -

having two models on a ListView in django
I have set a ListView querry which works fine. I now want to add a star ratings to the thumbnail so that each car has its own customer star rating within the thumbnail. My present Listview is as such: class CarListView(FilterMixin, ListView): model = Car queryset = Car.objects.all() filter_class = CarFilter I am getting an error saying: 'str' object has no attribute '_meta' Now I think it is because I have not added the star ratings model which is an app on its own onto the ListView. Any idea how I can add the star ratings model here?
