How to swap django-authtools for django.contrib.auth
I'm currently working on a project which makes use of django-authtools. This is something we want to move away from and to go back to using the django.contrib.auth package. What would be the best way to go about this? I need to preserve all existing user accounts and can't seem to have the auth_user and authtools_user tables co-exist. -
Django (Trying to use pagination with filter)
I am trying to add Pagination to my queryset with filter, filter seems to work but pagination doesn't. Can someone let me know what changes i need to make so that pagination works.

Django - Check if a variable set exists in the Database and process it if it does?
So I have a Django App, where a CSV-File can be uploaded. My CSV-File has 9 columns that can be divided into two "datasets" where the first 5 columns need to be handled as one information and the other 4 need to be handled as another information. I cannot put the first 5 in one cell and the other ones in another cell. I would like to check whether or not the first dataset exists and if it does, process it. The same applies to the other dataset. And if both datasets do not exist already it should just update the Database with get_or_create. Here is my views.py idea def import_csv(request): if request.method == "POST": with open('C:/Users/admin/Desktop/djangoexcel/b.csv') as file: reader = csv.reader(file) for row in reader: var = CSV_File4.objects.filter( attr1=row[0], attr2=row[1], attr3=row[2], attr4=row[3], attr5=row[4], ) if var.exists(): TemplateResponse(request, "documents/replace_entry.html", {'var' : var}) else: for row in reader: switch = CSV_File4.objects.filter( attr6=row[5], attr7=row[6], attr8=row[7], attr9=row[8] ) if var2.exists(): TemplateResponse(request, "documents/replace_entry.html", {'var2' : var2}) else: for row in reader: _, p = CSV_File4.objects.get_or_create( attr1=row[0], attr2=row[1], attr3=row[2], attr4=row[3], attr5=row[4], attr6=row[5], attr7=row[6], attr8=row[7], attr9=row[8] ) return redirect('documents:index') form = UploadFileForm() return render( request, "documents/csv_upload.html", {"form": form} ) It should look something like this.

How to annotate count based on nested JSONField in Django 1.11 and postgres 9.6
My model currently looks like: class Review(models.Model): source = models.CharField(max_length=80, blank=True, null=True) metadata = JSONField(default=dict) entity_type = models.CharField(max_length=255, blank=True, null=True) Example object of class Review: { "source": "amazon", "entity_type": "media", "metadata": [ { "product": 123456 }, { "product": 012345 } ] } I want to annotate count based on "source", "entity_type", "metadata_product" I am talking about Django query similar to: Review.objects.filter().values( "source","entity_type","metadata__product" ).annotate(count=Count('id')) which will obviously not work. I want to get output query set similar to: [{"source": "amazon", "entity_type": "media", "metadata_product": 123456, "count": 1}, {"source": "amazon", "entity_type": "media","metadata_product": 012345, "count": 1}] I want to achieve this using Django ORM and not resort to python because the table contains data close to 10 or 20 million. If that is not possible it will be really good if someone can suggest raw SQL query which can be put in Django ORM raw SQL method. -
uwsgi segmentation fault when serving a django application

On the new server, the application works fine when used using Django's runserver. To test the django application under uwsgi, I used uwsgi --http :8000 --module mysite.wsgi This opens the django admin page as expected but as soon as I try to login, uwsgi gets a segmentation fault error which is as follows. Would greatly appreciate if anybody could help understand what this means, and how might I fix this. *** uWSGI is running in multiple interpreter mode *** spawned uWSGI worker 1 (and the only) (pid: 15398, cores: 1) !!! uWSGI process 15398 got Segmentation Fault !!! *** backtrace of 15398 *** uwsgi(uwsgi_backtrace+0x35) [0x5569e2f17555] uwsgi(uwsgi_segfault+0x23) [0x5569e2f17903] /lib/x86_64-linux-gnu/libc.so.6(+0x35fc0) [0x7f0dd221bfc0] /home/vikas/ssersurvey/env/lib/python3.6/site-packages/psycopg2/.libs/./libssl-1d6df745.so.1.0.2p(ssl3_cleanup_key_block+0xb) [0x7f0dd0241cab] /home/vikas/ssersurvey/env/lib/python3.6/site-packages/psycopg2/.libs/./libssl-1d6df745.so.1.0.2p(ssl3_clear+0x16) [0x7f0dd023f5a6] /home/vikas/ssersurvey/env/lib/python3.6/site-packages/psycopg2/.libs/./libssl-1d6df745.so.1.0.2p(tls1_clear+0x9) [0x7f0dd024b219] /usr/lib/x86_64-linux-gnu/libssl.so.1.1(SSL_new+0x43f) [0x7f0dd2bf376f] /home/vikas/ssersurvey/env/lib/python3.6/site-packages/psycopg2/.libs/libpq-3a62a61f.so.5.11(+0x23969) [0x7f0dd04d6969] /home/vikas/ssersurvey/env/lib/python3.6/site-packages/psycopg2/.libs/libpq-3a62a61f.so.5.11(+0x24fc5) [0x7f0dd04d7fc5] /home/vikas/ssersurvey/env/lib/python3.6/site-packages/psycopg2/.libs/libpq-3a62a61f.so.5.11(PQconnectPoll+0xb78) [0x7f0dd04c1ba8] /home/vikas/ssersurvey/env/lib/python3.6/site-packages/psycopg2/.libs/libpq-3a62a61f.so.5.11(+0xfa28) [0x7f0dd04c2a28] /home/vikas/ssersurvey/env/lib/python3.6/site-packages/psycopg2/.libs/libpq-3a62a61f.so.5.11(PQconnectdb+0x1f) [0x7f0dd04c541f] /home/vikas/ssersurvey/env/lib/python3.6/site-packages/psycopg2/_psycopg.cpython-36m-x86_64-linux-gnu.so(+0x12651) [0x7f0dd0716651] /home/vikas/ssersurvey/env/lib/python3.6/site-packages/psycopg2/_psycopg.cpython-36m-x86_64-linux-gnu.so(+0x133df) [0x7f0dd07173df] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(+0x1fcab2) [0x7f0dd25d9ab2] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(_PyObject_FastCallDict+0x89) [0x7f0dd2645e99] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(_PyObject_CallFunction_SizeT+0x124) [0x7f0dd26468b4] /home/vikas/ssersurvey/env/lib/python3.6/site-packages/psycopg2/_psycopg.cpython-36m-x86_64-linux-gnu.so(+0xc1a8) [0x7f0dd07101a8] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(PyCFunction_Call+0x96) [0x7f0dd25f0fe6] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(_PyEval_EvalFrameDefault+0x7940) [0x7f0dd2561f10] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(+0x17ba3f) [0x7f0dd2558a3f] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(PyEval_EvalCodeEx+0x3e) [0x7f0dd25594fe] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(+0x23cc63) [0x7f0dd2619c63] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(PyObject_Call+0x48) [0x7f0dd26466d8] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(_PyEval_EvalFrameDefault+0x3de5) [0x7f0dd255e3b5] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(+0x17a8a3) [0x7f0dd25578a3] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(+0x17c2eb) [0x7f0dd25592eb] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(_PyEval_EvalFrameDefault+0x4ec2) [0x7f0dd255f492] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(+0x17a8a3) [0x7f0dd25578a3] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(+0x17c2eb) [0x7f0dd25592eb] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(_PyEval_EvalFrameDefault+0x4ec2) [0x7f0dd255f492] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(+0x17a8a3) [0x7f0dd25578a3] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(+0x17c2eb) [0x7f0dd25592eb] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(_PyEval_EvalFrameDefault+0x4ec2) [0x7f0dd255f492] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(+0x17ba3f) [0x7f0dd2558a3f] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(+0x17c11e) [0x7f0dd255911e] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(_PyEval_EvalFrameDefault+0x4ec2) [0x7f0dd255f492] /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0(+0x17a8a3) … -

Django form prefix separator hyphen to underscore
The naming process for django-formtools seems to be breaking the ability to access variables in session data. The form I have named patient_details but it's fields are being separated by - for example patient_details-upper_arch. I'm trying to access the session data to manipulate a form further along in the wizard based on a selection in the first form. However when trying to access {{ ...patient_details-upper_arch }} it throws a TemplateSyntaxError Could not parse the remainder: '-upper_arch' from ...patient_details-upper_arch Is there a way to set the separator to an underscore to make this variable accessible in the template, or another way around this? -

Django DRF APITestCase chain test cases
For example I want to write several tests cases like this class Test(APITestCase): def setUp(self): ....some payloads def test_create_user(self): ....create the object using payload from setUp def test_update_user(self): ....update the object created in above test case In the example above, the test_update_user failed because let's say cannot find the user object. Therefore, for that test case to work, I have to create the user instead test_update_user again. One possible solution, I found is to run create user in setUp. However, I would like to know if there is a way to chain the test cases to run one after another without deleting the object created from previous test case. -
Validate form and formsets with django
I'm trying to set my form validation in my view and I would like to get you help because I have a little issue. This is my formset : DocumentFormSet = inlineformset_factory(Publication, Document, form=DocumentForm, extra=1, max_num=4, can_delete=True) This is my code : def get_context_data(self, **kwargs): context = super(PublicationCreateView, self).get_context_data(**kwargs) document_queryset = Document.objects.all() context['FormSets'] = DocumentFormSet(self.request.POST or None, self.request.FILES or None, prefix='doc', queryset=document_queryset) return context def form_valid(self, form): try: context = self.get_context_data() formsets = context['FormSets'] if form.is_valid(): self.object = form.save(commit=False) if formsets.is_valid(): formsets.instance = self.object formsets.save(commit=False) for element in formsets: element.save(commit=False) self.object = form.save() formsets.save() return super(PublicationCreateView, self).form_valid(form) except IntegrityError: ... I read some things, especially form has to be save before forms in formset if there is ForeignKey between form and forms in my formset. The issue comes if I have wrong field in my formset. As the first form is saved, it creates an object with only the first form and not with the associated form in my formset. This is an example : As you can see, it saves my first form, but I don't want until all the formset is valid. I have to switch between .save(commit=False) and .save() methods. Thank you -

Reverse relationships in Nested serializer in django rest framework
My models.py is as as follows: class Group(models.Model): name = models.CharField(max_length=50, unique=True) class Policy(models.Model): name = models.CharField(max_length=50, unique=True) source_group = models.ForeignKey(Group, related_name='source_group') destination_group = models.ForeignKey(Group, related_name='destination_group') Since I have two foreign keys, pointing to the same model, I am using related name to avoid clashes. Now, when I try to create a serializer for Groups in order to list all Policies associated with it, I do the following: class PolicySerializer(serializers.ModelSerializers): class Meta: model = Policy fields = "__all__" class GroupSerializer(serializers.ModelSerializer): policy = PolicySnippetSerializer(source ='source_group', many=True) class Meta: model = Group fields = ['id', 'name', 'policy'] However, this will give me only policies for a a source_group.How did i get all groups associated with a group, source and destination ? -
