Nonetype check in django conditional expressions
Let's say we have two models, as below: class DefaultDescription(models.Model): first_attr = models.IntegerField() second_attr = models.CharField(max_length=20) description = models.CharField(max_length=100) class SomeEntity(models.Model): first_attr = models.IntegerField() second_attr = models.CharField(max_length=20) # and some other unimportant attributes... @property def description(self): try: return DefaultDescription.objects.get(first_attr=self.first_attr, second_attr=self.second_attr).description except DefaultDescription.DoesNotExist: return '' What I want to do is to write a single query for SomeEntity to fetch all of the descriptions. As you can see, the description property will run a queryset, which means a queryset for each entity. So I've tried some queryset like this: class DescriptionAnnotationQS(models.QuerySet): def annotate_descriptions(self): self.annotate( desc=models.Case( models.When( DefaultDescription.objects.filter( first_attr=models.F('first_attr'), second_attr=models.F('second_attr')).exists(), then=models.Value(DefaultDescription.objects.get( first_attr=models.F('first_attr'), second_attr=models.F('second_attr')).description)), default=models.Value('') ) ) I used Case and When to check if there wasn't any default description for the entity. But still I get DoesNotExist exception! I thought then section will not be executed unless the condition returns True. Is there any way to annotate SomeEntity with description with none type check? P.S: I get this problem from a legacy code which I'm not allowed to establish relations between models. -

How can i redirect user to obtain new access token in refresh token view if access token is expired ? i implemented cookie based authentication with simple jwt library in django rest framework. refresh token and access token are finely generated.

Redirect route from ajax using class based view subclasses in Django
I'm curios and just got started learning about class based views in Django and I'm testing it with AJAX. The idea is to get the data from the object (1/get-report) and redirect from AJAX to url which will be rendered from subclass (show_report route below). This is what I have: urls.py path("<int:pk>/get-report", ShowReportForDevice.as_view(), name="daily-report"), path("show-report/", ShowGraphReport.as_view(), name="show-report"), views.py # Parent class class ShowReportForDevice(DetailView): model= ModbusDevice #queryset = ModbusDevice.objects.all() template_name= None checked_vars=[] dev_id=-1 def get(self, request, *args, **kwargs): if request.is_ajax(): # Data from client I want to be visible in the child class (methods) self.checked_vars= request.GET.getlist('myvars[]') #myvars= kwargs.get('myvars[]') # None self.dev_id= request.GET.get('dev_id') # response created: data={} data['redirect']='/show-report' data['success']=True return JsonResponse(data, status=200) # Child class class ShowGraphReport(ShowReportForDevice): template_name= 'modbus_app/report2.html' data={} # Q1: Do I need to overrided this method if I only need parent class attributes? # Q2: Is "context" variable parent attribute ?

Django REST Framework : How to make a custom Validator to validate a combination of several fields at once?
I need to make a custom validator as below. But I can't find any way to retrieve the values of several fields, on which I need to check a condition. class MyCustomValidator(): def __call__(self, field_1, field_2): if condition_on_field_1_and_field_2 is True: message = 'my custom message' raise serializers.ValidationError(message) I saw in the Documentation that there is a way to provide context to a validator. But it seems to provide only one "serializer_field". Is there any way to retrieve more than one serializer field ? How would you do it? -
How to configure HTTPS for Django server on IIS 10
My client is developed using Vue and server using Django. We've hosted this on IIS 10. As for the SSL certificate we got from GoDaddy. I was successfully able to configure to the client. However when I run the app, I'm getting the following error. Mixed Content: The page at 'https://xxx.yyy.com/' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://x.x.x.x:xxxx/yyyy/'. This request has been blocked; the content must be served over HTTPS. What I understand is that we need to configure the Django server to allow HTTPS. Need assistance on how to achieve the same. Thanks!! -

Building an offline web system and updating the new versions remotely after entering data
I wanna create an offline web system that is working on a local server. the user can enter data offline and it will be saved locally. Then, the data will be synced to an online server whenever the internet is available. let me explain the steps a little bit more: 1- User can sign up to an account on a website. 2- After login the user can download an app to his/her device, which containing an offline web app with local database. 3- The user will use the local system to enter his data and organize it offline. 4- whenever the internet is available the data will be synced immediately. 5- if there is a new version of the system or the database the user can update the system without effecting on his entered data. so, my questions are: what is the best technologies(languages, DBs, etc.) to build such a system? how I can update the version and database without effecting the data? I have good experience on python, django, pyqt, etc. is python and its frameworks capable of building such a system. Thank you. -

How to create some restrictions for users?
I want to split my application into modules. So each user will have permission to enter certain pages. There are pages such as; Add new user See user list User Performance Assigned customers ... on the menu. For example some users can see one of them and other users can see 2 of them etc.. Should I create an attribute as models.BooleanField for each one and if it is true, user can see otherwise cannot see. I have at least 10 function like this in my menu, I'm not sure it will be the most efficient way. How can I handle this problem? Is there a better way? -
How to edit output of elasticsearch shown in the rest framework and can we show the output in a custom page?

JQuery: Select options not getting shortlisted based on radio button selection by using a passed Django variable
I want to provide the functionality to shortlist (reduce) the options inside select on the basis of the value of the radio button that is selected I am currently doing this using a PlugIn in JQuery that looks like this - jQuery.fn.filterOn = function (radio, values) { return this.each(function () { var select = this; var options = []; $(select).find('option').each(function () { options.push({ value: $(this).val(), text: $(this).text() }); }); $(select).data('options', options); $(radio).click(function () { var options = $(select).empty().data('options'); var haystack = values[$(this).attr('id')]; $.each(options, function (i) { var option = options[i]; if ($.inArray(option.value, haystack) !== -1) { $(select).append( $('<option>').text(option.text).val(option.value) ); } }); }); }); }; I used this plugin from here - https://stackoverflow.com/a/878331/11827709 You just pass a dictionary to this PlugIn and it shortlists the select options for you If I pass the dictionary hardcoded to this function like this - $(function () { $('#config').filterOn('input:radio[name=core]', { 'A': ['A1', 'A2', 'A3'], 'B': ['B1', 'B2', 'B3'], 'C': ['C1', 'C2', 'C3', 'C4', 'C5', 'C6'] }); }); The shortlisting works fine Like if I select 'A' in the radio button I can only see A1, A2, and A3 in the select menu But if I replace it with a variable that I pass from a …
