I am trying to create an app in Django where registered users can log in and access certain information from the main database
I am trying to create an app in Django where registered users can log in and access certain information from the main database, but I know how to make a filter in Django when the user logs in and on the welcome page show only the database items that I want to show to that user .. Do I have to create a model for each User separate from the login? I appreciate your help -
Is their a straightforward way to limit the number of updates of a certain field in a django model?
For example i use the extended user model called "profile" and in the profile i have many fields describing the using. what i want is that the user choose whether he is a business user or a regular customer on the web site. but once this field is updated it cannot be updated again, in which the field appears in the profile edit form but as non-editable field. What is the best way to do that? I thought of using an additional field in the database where i include an "update date" and if this field is not null then the user cannot update. but it seems to me too much coding for this small feature. Thanks in advance -
Django DetailView but get_object_or_404() instead of get_object()
I have Django Model that has a live boolean attribute. I want the View to get the Model by slug and only go to this page if it's live USING THE DetailView (not function based view, because I want to see how to do it. Model definition # myapp/models.py class MyModel(models.Model): name = models.CharField(max_length=255) live = models.BooleanField(default=True) slug = models.SlugField() def save(self, *args, **kwargs): self.slug = slugify(self.name) I hoped it would be done something like this: class ModelDetailView(DetailView): model = MyModel def get(self, request, *args, **kwargs): service = self.get_object_or_404(Service, live=True) # <- Main point of what I'm looking for help with return super().get(request, *args, *kwargs) Is there a way to filter this way? -
the google map is not showing the nearby results of carwashes?
Any guidance will be helpful! I have implemented some code in my apps in Django as map.html(code is below). The app is able to locate the user's location but it does not show the nearby results of carwashes? do I need to be more specific in the code or am I completely missing something?

How to use a Formset with Django_Tables2
I love using django_tables2 but I've hit a bit of a snag. I have an edit page with a standard django form for updating a member's details. Within this form there is a table of addresses for the current member which I can render easily with django_tables2 using the following code. from tables.py class AddressTable(tables.Table): address1 = tables.Column(attrs={'th':{'class':'centered nodec'}, 'td':{'data-title':'Address 1'}}) address2 = tables.Column(attrs={'th':{'class':'centered nodec'}, 'td':{'data-title':'Address 2'}}) address3 = tables.Column(attrs={'th':{'class':'centered nodec'}, 'td':{'data-title':'Address 3'}}) address4 = tables.Column(attrs={'th':{'class':'centered nodec'}, 'td':{'data-title':'Address 4'}}) address5 = tables.Column(attrs={'th':{'class':'centered nodec'}, 'td':{'data-title':'Address 5'}}) postcode = tables.Column(attrs={'th':{'class':'centered nodec'}, 'td':{'data-title':'Postcode'}}) class Meta: model = Address fields = ('address1','address2','address3','address4','address5','postcode',) template_name = 'django_tables2/bootstrap.html' attrs={'id':'addresslist', 'class': 'table table-noborder no-table'} and I pass the data from my view like like this from views.py f = AddressListFilter(request.GET, queryset=Address.objects.all(),request=request) addresstable = AddressTable(f.qs) However, the page needs to allow the user to be able to dynamically add as many extra address records as they wish (which I can use javascript to do this) but I then need to pass the entire table, complete with additional address records, back to django for processing when the user hits the submit button within the form.

How to keep the API running and also Consume Pika (RabbitMQ) parallelly
I have a set of API endpoints serving in the Django app. But I also want to consume a queue(from Pika, a message broker) and execute a function when there is a message in the queue. If I consume a queue, it is blocking the thread and API stops serving. I'm not sure how to achieve this. Do I have to use [background tasks][1] or use Multi-Threading to create a new thread and use it to consume? Any sample code to achieve this is much appreciated.

How do I properly implement Django formsets with a CreateView ( Class Based View )?
And thanks in advance for any suggestions. I have been playing around with how to properly implement formsets with a CreateView for a couple of days and I'm stuck. Here is my code.

How do you format a Django datepicker as ISO 8601?
We need to display dates in ISO 8601 (yyyy-mm-dd) format throughout our Django site. The dates that we are getting from the database show correctly, however date pickers do not. When I run the django test server in ubuntu, the datepicker appears to use the locale that the OS is set to. When I run the same code in Windows, it uses dd/mm/yyyy. The various input_formats args appear to be getting overridden somehow, even though I have set them everywhere I can find. Is it possible to force datepickers to display yyyy-mm-dd regardless of client settings? If so, how? Here is the code we have so far. forms.py ... class DateInput(forms.DateInput): input_type = "date" input_formats = ["%Y-%m-%d"] options = { "format": "%Y-%m-%d", "autoclose": True } class RegistrationForm(forms.Form): full_name = forms.CharField(max_length=255, required=True) preferred_name = forms.CharField(max_length=255, required=False) email = forms.EmailField(required=True) password = forms.CharField( max_length=255, required=True, widget=forms.PasswordInput, help_text=password_validation.password_validators_help_text_html(), ) birth_date = forms.DateField(required=True, widget=DateInput, input_formats=["%Y-%m-%d"]) ... settings.py ...

How to test Django messages for a Class Based FormView?
I am struggling to find the proper way to test a FormView. I would like to check if the message (generated through django.contrib.messages) is rendered when the user is not authenticated. I have already read about RequestFactory, Client, Mock, Middleware and I was not able to implement this test in CBV FormView. The problem is not about authenticating user particularly, I want to use the logic in other fields also to test other messages. Here is my code: View: class MyView(FormView): form_class = MyForm template_name = 'app/welcome_template.html' def form_valid(self, form): form_data = form.cleaned_data auth = LDAPBackend() user = auth.authenticate(self.request, username=form_data['login_field'], password=form_data['password_field']) if user: return super(MyView, self).form_valid(form) else: messages.add_message(self.request, messages.WARNING, 'some warning' + str(form_data['other_field'])) return self.form_invalid(form) Form: class MyForm(forms.Form): login_field = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Login', 'class': 'form-control form-control-sm'}), label='Login:', max_length=20) password_field = forms.CharField(widget=forms.PasswordInput(attrs={'placeholder': 'Password', 'class': 'form-control form-control-sm'}), label='Password:', max_length=20) other_field = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Select ...', 'class': 'form-control form-control-sm', 'max': '99999999'}), label='Other:') Template: <form autocomplete="off" onsubmit="$('#ModalCenter').modal({backdrop: 'static', keyboard: false})" action="." target="_top" method="post"> {% csrf_token %} <div class="row"> <div> {% if messages %} {% for message in messages %} <div class="alert {% if message.tags %}alert-{{ message.tags }}{% endif %}" role="alert">{{ message }}</div> {% endfor %} {% endif %} </div> <div class="form-group mt-2"> {{ form.login_field.label_tag }} {{ … -

Python / Django - Generating API Documentation - Not using Django Rest
I am working on a Django project that does not use Django Rest On top of this code base I am trying to build a framework to autogenerate swagger documentation From this S.O. Post I am able to get the available Urls: from django.urls import get_resolver urls = get_resolver().reverse_dict urls is a MultiValueDict, here are the first few items in the Dict: MultiValueDict: { <function create_demo at 0x10f6a3820>: [( [('api/v1/create-demo', [])], 'api/v1//create\\-demo$', {}, {} )], 'create_demo': [( [('api/v1/create-demo', [])], 'api/v1/create\\-demo$', {}, {} )], <function users_detail at 0x10f67d280>: [( [('api/v1/users/users/%(user_id)s', ['user_id'])], 'api/v1/users/users/(?P<user_id>[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12})$', {}, {'user_id': <django.urls.converters.UUIDConverter object at 0x10bc3c6a0>} )], 'users_detail': [( [('api/v1/users/users/%(user_id)s', ['user_id'])], 'api/v1/users/users/(?P<user_id>[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12})$', {}, {'user_id': <django.urls.converters.UUIDConverter object at 0x10bc3c6a0>} )] It appears the keys for this dict are a reference to a view function, followed by the url "name" for that function, and the values are lists containing the relative url path and params. My thought is to loop through each function reference and create an entry for the swagger doc. Inside each view function, I will define vars named RequestSchema and ResponseSchema. Ideally I can access those vars, from the function reference, and add that data to the swagger doc as well. The goal is to have documentation that … -

Mozilla Django OpenID Logout does not revoke token
I've been working to integrate a django app with mozilla-django-oidc and I can't seem to figure out how to log out of the thing correctly. On my main page I have <form action="{% url 'oidc_logout' %}" method="post"> {% csrf_token %} <input type="submit" value="logout"> which provides the logout assuming a user is logged in. Logging in seems to work well enough. In my settings I'm providing the logout configurations OIDC_OP_LOGOUT_ENDPOINT = cfgs.get("LOGOUT_ENDPOINT") OIDC_OP_LOGOUT_METHOD = "test_app_2.openid.logout" LOGOUT_REDIRECT_URL = reverse('post-logout') POST_LOGOUT_URL = cfgs.get("LOGOUT_REDIRECT") Which are my okta oidc logout endpoint, the method that I wrote to create the correct logout url and logout redirect. I created a POST_LOGOUT_URL variable so I can access the post-logout url elsewhere. openid.logout looks like this def logout(request): id_token = str(request.COOKIES['csrftoken']) logout_request = \ f'{settings.OIDC_OP_LOGOUT_ENDPOINT}?id_token_hint={id_token}' \ f'&post_logout_redirect_uri={settings.POST_LOGOUT_URL}' return logout_request Which is the correct logout url configuration for oidc. I've tested all this through a flask app and it all works just fine. Why don't I just use flask? It's a long story. I'd rather use Django... In my views.py I have class LogoutView(OIDCLogoutView): def get(self, request): return self.post(request) Which I confess to have grabbed from another post and I'm not entirely sure how it works with my urls … -

Django DRF - jwt vs simplejwt
I have been ramping up on Django Rest Framework and JWT authentication through tutorials that point to django-rest-framework-jwt but while researching how to customize JWT validation, realized that there is a newer implementation django-rest-framework-simplejwt. The older jwt package does not have a commit since 2017 but simple-jwt is actively maintained and developed, and from what I can find, has better security features. It is also the recommended link in the DRF documentation. I could not find a relevant post on S/O but I found that JoelGoh92 in this git issue summarizes the problem well: 1. In most JWT implementations, an access token + a refresh token is returned. Otherwise the other option, if only a single token is desired, is the sliding token approach. With simple-jwt, the jwt can be configured to either of these implementations, whichever is required. 2. With the current django-rest-framework-jwt supported by rest-auth, the only approach available is similar to the sliding token approach, except that it has no way to blacklist a previously generated jwt token, e.g. by logout on user end.

I have configured cache in settings.py in my Django project as follows: CACHE_MIDDLEWARE_ALIAS = 'Cache' CACHE_MIDDLEWARE_SECONDS = 60 CACHE_MIDDLEWARE_KEY_PREFIX = '' CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': '127.0.0.1:11211', } } Cache service is running after I typed: $ memcached -p 11211 & But when I try to run server, the following error shows up: django.core.cache.backends.base.InvalidCacheBackendError: Could not find config for 'Cache' in settings.CACHES What I am doing wrong? -

Django - annotate price= "price_A" or "price_B"
I have multiple fields that stores the same value type (price) from different sources. class Product... price_amazon = ... price_ebay = ... price_etsy = ... @property def price... return self.price_amazon or self.price_ebay or self.price_etsy I'm looking for a way to annotate price to each Product from queryset. It should behave exactly as the price property. price is either price_amazon, price_ebay or price_etsy - the first not None value. How would you do that? I tried: Product.objects.all().annotate(price=F('price_amazon') or F('price_ebay') or F('price_etsy')) which raises: AttributeError Traceback (most recent call last) ~/PycharmProjects/.virtualenvs/freedomprogress.cloud/lib/python3.8/site-packages/IPython/core/formatters.py in __call__(self, obj) 700 type_pprinters=self.type_printers, 701 deferred_pprinters=self.deferred_printers) --> 702 printer.pretty(obj) 703 printer.flush() 704 return stream.getvalue() ~/PycharmProjects/.virtualenvs/freedomprogress.cloud/lib/python3.8/site-packages/IPython/lib/pretty.py in pretty(self, obj) 392 if cls is not object \ 393 and callable(cls.__dict__.get('__repr__')): --> 394 return _repr_pprint(obj, self, cycle) 395 396 return _default_pprint(obj, self, cycle) ~/PycharmProjects/.virtualenvs/freedomprogress.cloud/lib/python3.8/site-packages/IPython/lib/pretty.py in _repr_pprint(obj, p, cycle) 698 """A pprint that just redirects to the normal repr function.""" 699 # Find newlines and replace them with p.break_() --> 700 output = repr(obj) 701 lines = output.splitlines() 702 with p.group(): ~/PycharmProjects/.virtualenvs/freedomprogress.cloud/lib/python3.8/site-packages/django/db/models/query.py in __repr__(self) 261 262 def __repr__(self): --> 263 data = list(self[:REPR_OUTPUT_SIZE + 1]) 264 if len(data) > REPR_OUTPUT_SIZE: 265 data[-1] = "...(remaining elements truncated)..." ~/PycharmProjects/.virtualenvs/freedomprogress.cloud/lib/python3.8/site-packages/django/db/models/query.py in __len__(self) 267 268 def __len__(self): --> …
