How can I get Django Form ModelChoiceField values from Class View back to the template from which they came
I am trying to display a list of tests, select one with ModelChoiceField Form and then display the selected test information on the same template the ModelChoiceField is on. (2 fields - the ID number and the name) as a link. So basically you select the test, it appears under the ModelChoiceField as a link and then you click it go to a detail screen. I can capture the selected choice information in the class view in form_valid but I don't know how to return to the template with this new information. Tried various approaches with context etc. but nothing is working. The screen will look something like this: When you press the select button the test selected will appear on the same screen. I need access to both the name and id number, which I get in form_valid # forms.py class TestBrowseForm(forms.Form): choice = forms.ModelChoiceField( Universal_Test_File.objects.all().order_by('test_name'), to_field_name="service_id") # views.py class ListTests(FormView): model = Universal_Test_File context_object_name = "testlist" form_class = TestBrowseForm template_name = "lab/list_tests.html" success_url = '/list_tests/' def form_valid(self, form): # choice is a queryset with both service_id and testname so we need to specify service_id choice = form.cleaned_data.get("choice") ## I want to display the test_name and link to service_id … -
Restrict user registration with registration key
I want to restrict who can register on my site. I want to achieve this by asking for a registration key in the registration form. The key should be valid X amount of times, so not it can not be used by everyone forever. I have created two separate models, one user model and one registration key model. In the User model, have I created a key field, which is a foreign key related to the registration key model. These are my two models class RegistrationKey(models.Model): key = models.CharField(max_length=30) max_amount = models.IntegerField(null=True) class User(AbstractUser): ... key = models.ForeignKey(RegistrationKey, on_delete=models.CASCADE) The problem however is that I don't know how to validate that the key the user enters in the registration form is registered in the model and that the key is still valid, in other words still not being used more than X times. I would appreciate all sorts of help, even sources that describes similar problems because I have not been able to find any. -

Now I need to save certain forms to a sqlite database and I've watched some tutorials however I cannot understand how to do this.

Microsoft Azure - how to locate ML models
I have been writing Python for a number of years and I'm at a fairly decent level. I have never formally studied Computer Science. I have been reading about and using Azure Cognitive Services for one of my applications which uses the Microsoft Azure Cognitive Service' textanalytics service for Language Detection based on text input. As per my understanding Microsoft (MS) has trained some powerful ML models that are used for their cognitive services package. I understand that all the code is open source: https://github.com/Azure/azure-sdk-for-python/tree/main/sdk/textanalytics/azure-ai-textanalytics/azure/ai/textanalytics And I am able to do some basic navigation through the SDK documentation and repo to solve my purpose. However, I want to understand that if Microsoft does use a ML model for the text analytics service or any other cognitive service where is the actual model saved in the repository. While navigating the repository I was expecting to find a call to some sort of serialized file (eg .pkl, .yaml) which loads the model and makes a prediction / returns an output. However, for the life of me, after spending a couple of hours I am lost in this massive repo with no results. To make it easier, I'd be interested to know where … -
What is the difference between default LoginView and creating my own form with authentication in Django? One works, the other doesn't with LDAP
I ask this because I use ldap to authenticate users. A user logs in with the default Django LoginView and in the back ldap does all the checks and it works. However, if instead I customize my own login method with authentication, it no longer works. I know my login method is correct because it works in applications without ldap. So I wonder what are these differences... To be more precise... here are the two examples: 1)This is my customized method: def login_page(request): login_data = LoginForm() return render(request, 'login.html', {'login_data':login_data}) def login_validate(request): login_data = LoginForm(request.POST) if login_data.is_valid(): user = auth.authenticate(username=request.POST['username'], password=request.POST['password']) if user is not None: if user.is_active: auth.login(request, user) return redirect('/') error_message= 'Incorrect password / username. Try again.' return render(request, 'login.html', {'login_data':login_data,'login_errors':error_message}) error_message= 'Internal error. Please contact the administrator.' return render(request, 'login.html', {'login_data':login_data,'login_errors':error_message}) It doesn't work with ldap... however if instead I choose 2)Default login: def login(request): return LoginView.as_view(template_name='login.html')(request) it works with ldap ...both work in applications without ldap.. so what is the difference between both. I don't show the ldap set up but is the default installation of django-ldap. What makes LoginView special in this case? If there are differences, then how do I customize my own login … -

Django app w/Python and JS: Alert modal is not produced when user does not apply search filters to jqGrid
Below I have some python logic for a Django view that takes the search_query and checks if the data the user wants to download has had filters applied, to prevent them from downloading all database records for every page of the grid. The code does reach return JsonResponse; I have checked that. However, the corresponding JS function does not produce the alert modal. There is another piece of js code adjacent to my if(gridData["export_Error"] does produce a modal for a separate gridData value, but why would mine not be working? It seems to attempt to produce the exported CSV instead of stopping to show a modal filters = search_query['filters'][0] filter_list = filters.split('[')[1] list_fields = re.findall("\{(.*?)\}", filter_list) no_search = False for search_filter in list_fields: filter_data = search_filter.split(':')[-1] if filter_data not in ['"2"', '""', '"any"']: break no_search = True if no_search: data = { "export_error": "Results must be filtered before exporting.

I have a model for a "gym", and a model for a "workout": class Gym(models.Model): name = models.CharField(max_length=255) address = models.CharField(max_length=255) def __str__(self): return self.name class Workout(models.Model): gym = models.ForeignKey(Gym, on_delete=models.CASCADE) time = models.DateTimeField() I will also show the 'WorkoutSerializer': class WorkoutSerializer(serializers.ModelSerializer): gym = serializers.StringRelatedField() class Meta: model = Workout fields = ['gym','time'] as you can see, gym is represented in the workout json as a string of the field 'name'. here is the view for workout: @api_view(['GET','POST']) def workout_list(request): if request.method == 'GET': queryset = Workout.objects.select_related('gym').all() serializer = WorkoutSerializer(queryset, many=True) return Response(serializer.data) elif request.method == 'POST': serializer = WorkoutSerializer(data=request.data) serializer.is_valid(raise_exception=True) # rasis 400 bad request if needed serializer.save() return Response('ok') when I try to test a POST request with (I want to use the gym's str representation in POST as well): { "gym": "gym 2", "activity": "Yuga", "time": "2022-03-07T06:00:00Z", "participants": [ "Anna Boing" ] } I get the error: StringRelatedField.to_internal_value() must be implemented for field any idea why, and what can I do to fix this? -
how to create a hyperlink in matched results in Django search autocomplete trevoreyre
I am using autocomplete trevoreyre to handle autocomplete function in my search bar. For now, the user is redirected to the search_result page when clicking enter or search icon. The problem is that even if a suggestion appears user must click on title then click enter or search icon, then the function will redirect him to the search_results page, and then user can click on a card that is interested in. I'd like to extend this feature and create a hyperlink in title suggestions so if the user clicks on the title suggestion then the function should redirect the user directly to DetailedView page. I know that I should follow this logic: onSubmit: result => { window.open(`${wikiUrl}/wiki/${ encodeURI(result.title) }`) } but I am not sure how to create a link to DetailView pages if there are 3 models in my Django app and these models have different URLs. I want to add something like onclick event so when the user clicks on suggestion then it will redirect him to the DetailView page but if clicks enter or search icon it will redirect him to the search_result page. base.html <button onclick="openSearch()"><i class="fas fa-search fa-sm"></i></button> <form action="{% url 'search_result' %}" method="get" id="search"> … -
How to auto save data every month?
CentreInvoice model: class CentreInvoice(core_models.TimestampedModel): centre = models.ForeignKey(Centre, null=False, on_delete=models.CASCADE, related_name="c_centre_invoice") rcl_share_amount = models.FloatField(null=True) total_billed_amount = models.FloatField(null=True) start_date = models.DateField() end_date = models.DateField() paneluser = models.ForeignKey("panel.PanelUser", related_name="c_invoice_creator", on_delete=models.DO_NOTHING) invoice_no = models.CharField(max_length=255) total_advance_payment = models.FloatField(default=0) I am using this model to generate invoices in my project. I need to save this manually everytime, but I want it to happen automatically every month. Is there a way to do this? Any advice would be appreciated.
