Django ModelAdmin: how to ask password using two secret fields?
This is my custom user model: class CustomUser(AbstractUser): created = models.DateTimeField(auto_now_add=True) username = models.CharField(max_length=100, unique=True) email = models.EmailField(max_length=200, unique=True) company = models.ForeignKey(Company, on_delete=models.CASCADE, related_name='%(class)s_company') Since there is a foreign key field, I have created a custom ModelAdmin: class CustomUserAdmin(admin.ModelAdmin): exclude = ('groups', 'user_permissions', 'date_joined') list_display = ('username', 'email', 'company') Otherwise it works fine, but there is only one, clear-text password field shown. How can I modify it so that Django Admin would ask the password using the default two field approach? -
Djongo issue with "id" field and existing mongo db
I'm trying to use django+djongo and an already existing mondo database. The collection I need to read is like this: { "_id" : ObjectId("5dde69143f664504b7149fed"), "name" : "example_123456", "hash" : { "md5" : "d9feb4e791077aeba4e946696a2fbf8a", "sha256" : "72f7a877db57e43580495d0ac05615138a73e3f8507781188d4469b1bf09389b", "sha1" : "38e600408e141389d0bb0baaf6a2e0594411a34d" }, } So in my models.py I've created these two models: class Hash(models.Model): md5 = models.TextField() sha256 = models.TextField() sha1 = models.TextField() class Meta: db_table = "hash" abstract = True class ExampleCollection(models.Model): name = models.TextField() hash = models.EmbeddedModelField( model_container=Hash ) class Meta: db_table = "example_collection" Now the problem is that when I try to read something from this collection (for example even a ExampleCollection.objects.all()), I get a MigrationError: Exception Type: MigrationError Exception Value: id I've noticed (by creating a "test" model) that django/djongo automatically add an "id" field in my models (that acts as a primary key), but since it doesn't exist in this collection, I get this exception. -

Python - Create multiple user types and email as the username field in Django 2
I'm working on a project using Python(3.7) and Django(2.2) in which I have to implement multiple types of users as: Personal Account - below 18 Personal Account - above 18 Parent Account Coach Account Admin along with that, I also need to use email as the username field for login/authentication. The strategy I'm trying to use is to build a custom base model as User inherited from AbstractBaseUser and also created a custom User Manager to make the email as username but it's not working. Here's my complete model code: class UserManager(BaseUserManager): def _create_user(self, email, password, is_staff, is_superuser, **extra_fields): if not email: raise ValueError('Users must have an email address') now = timezone.now() email = self.normalize_email(email) user = self.model( email=email, is_staff=is_staff, is_active=True, is_superuser=is_superuser, last_login=now, date_joined=now, **extra_fields ) user.set_password(password) user.save(using=self._db) return user def create_user(self, email=None, password=None, **extra_fields): return self._create_user(email, password, False, False, **extra_fields) def create_superuser(self, email, password, **extra_fields): user = self._create_user(email, password, True, True, **extra_fields) user.save(using=self._db) return user def generate_cid(): customer_number = "".join([random.choice(string.digits) for i in range(10)]) return customer_number class User(AbstractBaseUser, PermissionsMixin): email = models.EmailField(max_length=255, unique=True) is_personal_above_18 = models.BooleanField(default=False) is_personal_below_18 = models.BooleanField(default=False) is_parent = models.BooleanField(default=False) is_staff = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) is_active = models.BooleanField(default=True) last_login = models.DateTimeField(null=True, blank=True) date_joined = models.DateTimeField(auto_now_add=True) USERNAME_FIELD … -
How to stop User Agent Stylesheet from overriding my CSS
I have the following CSS .imagetable{ border-collapse:collapse; width:100%; height:100%; } and HTML: <table class="imagetable"> <tr> <th><img src="{% static "images/myimage1" %}"></th> <th><img src="{% static "images/myimage2" %}"></th> </tr> <tr> <td><a href='myurl'><button>button1</button></a></td> <td><a href='myurl'><button>button2</button></a></td> </tr> </table> But whenever I run this and look in Google Chrome F12 I see not my own CSS but this: table { user agent stylesheet display: table; border-collapse: separate; border-spacing: 2px; border-color: grey; Annoyingly my CSS works everywhere else other than this table.

Start 'python manage.py runserver' of django within jupyter notebook
I would like to create small application in Django. However, main requirement for this application is to be started within jupyter notebook, as every user will have such application locally. Plotly dash (from which I would like to rewrite this app) allows app.runserver() inside jupyter cell, which afterwards starts the app. However this is not available for django in the jupyter notebook. I could do !python manage.py runserver This spawns server correctly. But this server is not 'killable' using the interrupt button inside jupyter notebook - which is important feature of this approach. Same applies for os.system or subprocess.Popen. I tried also approach from this question: Django runserver from Python script Which does not work in the jupyter notebook unfortunately. This raises zmq.error.ZMQError: Address in use Is there any other approach which I could try? -
Run specific function before executing any code in the view
I haven't worked too much with Django. Let's say I have three views. The url patterns that these views are mapped to all start with string Y. Suppose I want to run specific function X before running code that the views contain. Is there a way to run function X by adding it somewhere only once instead of adding the function call to to the beginning of each of these views separately? Would middleware be the recommended way to do this? -

API's of vCenter
We are using API's in our product to talk at vCenter. We are a quit new development team and want to update vCenter 6.5 to 6.7. I tried to find if this will have consequences for our code base in the form of deprecation or something. But I cant find anything regarding to this. Now this seem to mean that it should have no consequences. But before updating production I want to be sure. Does anyone has experience with this? -

How can i get the id of each record in ListApiView in DRF
I am facing an issue while getting the promary_ket(id) of record ListApiView in the Django rest framework. I am also implementing the Custom pagination. Here is my ListApiView Code: class TestList(ListAPIView): permission_classes = (IsAuthenticated, ) serializer_class = AllTestListSerializer pagination_class = CustomPagination def get_queryset(self): return TakeTestDetails.objects.filter(user=self.request.user).order_by('date', 'time').all() And here is my CustomPagination code: class CustomPagination(pagination.PageNumberPagination): def get_paginated_response(self, data): response_data = { 'status': '200', 'message': 'Success', 'count': self.page.paginator.count, 'next': self.get_next_link(), 'previous': self.get_previous_link(), } if data: new_cycle_data = [] for row in data: row_dict = dict(row) print(row) cycle_id = row_dict['cycle_id'] cycle = TestCycle.objects.get(id=cycle_id) cycle_no = cycle.cycle_no cycle_start_date = cycle.cycle_start_date cycle_end_date = cycle.cycle_end_date cycle_start_date = change_date_format(cycle_start_date) cycle_end_date = change_date_format(cycle_end_date) test_date = change_date_format(row_dict['date']) row_dict['date'] = test_date row_dict['cycle_no'] = cycle_no row_dict['cycle_start_date'] = cycle_start_date row_dict['cycle_end_date'] = cycle_end_date new_cycle_data.append(row_dict) response_data['data'] = new_cycle_data else: return Response({ 'status': '404', 'message': "You haven't performed any test yet", 'count': self.page.paginator.count, 'next': self.get_next_link(), 'previous': self.get_previous_link(), 'data': data }) return Response(response_data) Now what i want is also to get the primary_key/id of each row/record. But it's not giving me the id in data. How can i get the id? Thanks in advance -
Django: How to keep non-PII from removed users under GDPR
I'm using Django to build a B2B SaaS hobby project, where each company (tenant) can have many users and, eventually, remove them. It's important to keep the reason why a user was removed. The straightfoward way for this to be solved would be to turn is_active to False and add a reason_for_removal field on the User model. Then make sure is_active is indexed (is it by default in Django?) and all querysets are appropriately filtered. However, in a GDPR world, is this the right way to do it? Does it make sense to create a separate model called RemovedUser just with the user and reason_for_removal fields (and no other Personal Identifiable Information) and delete the original user instance? -
python requests taking 100% of cpu

Django formtools how to store form data between logout/login cycles
I am using django-formtools to split a long form in parts. This is working fine. However, I want users to be able to start filling the form going until let's say step 5 out of 9, then logout and login again and continue filling the form from step 5 on. I can do this with cookies but, if user A starts filling the form then logs out and then user B logs in, user B can see the data of user A if user B chooses to continue filling the form. This happens if users A and B use the same computer and web browser. This, of course, cannot happens. If I use sessions instead of cookies then when a user logs out it is not possible to continue filling the form from step 5 on because the session is flushed and the data deleted. So I guess that sessions will not help me here. In order to continue filling the form from step 5 on I override the get method of django-formtools.WizardView: def get(self, request, *args, **kwargs): """ To allow resume editing of a session storaged submissions """ if self.continue_fill == True: try: return self.render(self.get_form()) except Exception as e: … -
How to create multiple users in Django without letting them access each other's data
I am not quite sure if the title I used for my question is the right one. And if this has previously been answered, someone should please point me to it as I have tried so much to find that out but its been futile. I am currently working on a basic HR system which can be used by different companies. In a much clearer way, how can I create an online system whereby multiple companies can manage their employees online without having access to each other's data? And without even knowing that they use the same system? A perfect example of this kind of system is "Zoho People". -

Django Rest API - custom layout for xml Render
Im having trouble formatting XML output for a specific render. I need to have the XML format outputted like the below sample: <mappings> <mapping> <subnet from="192.168.1.1" mask="255.255.255.0"/> <location country="United States" region="California" city="San Francisco"/> </mapping> <default country="United States" region="California" city="San Francisco"/> </mappings> Ive tried two methods thus far both have failed, how can I achieve this xml output? Thanks First I create json fields in serialiser and create the json dict manually for subnet and location like below Serializer class SerializerDataGeoMapping(serializers.Serializer): subnet = serializers.JSONField() location = serializers.JSONField() View class DataGeoMapping(generics.ListAPIView): permission_classes = (IsAuthenticated,) serializer_class = SerializerDataGeoMapping paginate_by = 20 def get_queryset(self): queryset = SiteSupernet.objects.filter(site__is_live=True, subnet_type__subnet_type__icontains='site aggregate' ).select_related( 'site', 'site_type', 'subnet', 'subnet__subnet_type' ).values( 'site_id', 'mask', 'subnet', location=F('site__location'), country=F('site__country'), region=F('site__region'), city=F('site__town'), location_type=F('site__site_type__site_type'), ) for supernet in queryset: supernet['subnet'] = {"from" : supernet['subnet'], "mask" : supernet['mask']} supernet['location'] = {"country" : supernet['country'], "region" : supernet['region'], "city" : supernet['city']} output <root> <list-item> <subnet> <from>10.1.1.0</from> <mask>/24</mask> </subnet> <location> <country/> <region/> <city>Aberdeen</city> </location> </list-item> <list-item> <subnet> <from>10.3.3.0</from> <mask>/24</mask> </subnet> <location> <country/> <region/> <city>Edinburgh</city> </location> </list-item> ...

Dynamic select box in Django template without using JavaScript
I have a template page which displays a database table. The implementation I would like here is to have a set of select boxes to set filter parameters, then have a button to apply the selected filters. The problem here is some of my categories are a bit out of control with the amount of options available. So I would like to be able to select an option from selectbox1 and depending on the choice, the options in selectbox2 are filtered down by eliminating any null combinations. I reckon this is a fairly easily solved problem if I included some JavaScript in my solution but I want to know if there is a relatively tidy method of doing this purely within Django Views + Templates. -
Django - JupyterHub - OAuth2 - Jupyter Notebook Interaction
I have a rather complex requirement. Here is what I hope to achieve. A Django backend that shall host all kinds of information about the user of a service. User will log into Django backend and can send some instructions or query to the service. OR The user can access a Jupyter notebook from within the Django app and use an API to communicate the query to the service. This might be a preferred mode of accessing the service since the results are something that need further analysis using Python. Whether it is a query sent using a form within the Django service OR whether query is sent using a Python API from within a notebook, it is sent to the same web URL/endpoint so that the query can be logged etc. This URL is protected by authentication. Now, what I have managed to do so far is the following: Configure Django to provide OAuth based authentication. Configure JupyterHub to communicate with Django and start a user specific notebook server. I have even figured out how to use Jupyter Notebook Extensions to pre-populate any new notebook with the relevant code and comments that will help the user use our API. … -
