DRF Q Filter string working in Django shell_plus, but not in django-filter code
I have a DRF project where I use Q filters to filter the query set. The search value will be used to search a string field "name" and tested if it is an integer and then tested if it is eq to "port" or part of a range defined by "port" and "port_end". I need to modify the Q filter based on some conditions, so I thought it would be easy to define the query based on conditions and use it in the filter. I was thinking that there might be an issue that the value is a string and the field in the DB an integer. But that is not the case I also tried to have fixed values in the string as integer and string, but that was not the issue. Also a int(value) did not change anything. If I do this in the Django shell_plus, then I get proper results: >>> value = "22" >>> query = Q(name__icontains=value)|Q(port__exact=value)|(Q(port__lte=value)&Q(port_end__gte=value)) >>> items = MyObject.objects.filter(query) >>> print(items) If I do the same in my DRF filter code then the "items" query has only matches for the name field. query = Q(name__icontains=value)|Q(port__exact=value)|(Q(port__lte=value)&Q(port_end__gte=value)) items = queryset.filter(query) I have remove the filter on … -

How can I make a password confirmation in Django to access an specific page?

If i built a Django Website, can i make an api with Django Rest Framework of the same logic to make a mobile client later?
What i mean is lets say i have a totally functional and regular Django Web App. But then the client tells me they want a mobile client of the same app. So that means i should make an api, to get the data on the client. Django Rest Framework is the way to make api with Django, but i dont know if i can add the api layer after making the regular Django App and leverage or take advantage of the existing logic i have previously created so the both web app and api can coexist. Or if i should have started making the app with django rest framework from the begining.(Wich isnt convenient for me now). What do you think? What are my options? Thanks in advance! -

Django: A None DateInput does not pass through form validate. How can I fix it?
I use UpdateView and created a field called date_updated. When the user creates, e.g., a Group, there are zero updates. In models.py I defined: date_updated = models.DateTimeField(null=True) Then in forms.py I created the update form, e.g., class UpdateGroupForm(forms.ModelForm): class Meta: model = Group fields = ['name','date_updated'] In templates I call my form, as expected in the iteration {% for field in form %}, field.value = None for the specific field date_updated, and because of this I believe is not updating. In views.py I have the following in the UpdateGroup class def form_valid(self, form): if form.instance.owner == self.request.user: form.instance.date_updated = timezone.now() return super().form_valid(form) else: return super().form_invalid(form) I tried to replace the empty value with a fake date considering in my templates the following: {% if field.name == 'date_updated' and field.value == None %} <input type="date" name="date_updated" value="2000-01-01" format="yyyy-mm-dd" required disabled> {% else %} But it doesn't work also, I cannot validate the form and update my values with the first update.. What can I do? The only thing that works is to remove date_updated from forms.py, do the first updated and then restore it forms.py. Now because is not an empty Date everything works and I can proceed with a second … -

Save data from several models to one summary by the smallest size of one of this?
I have three databases - table models. In which there is a different amount of data - a different number of rows of elements in the database table. One table has 100 rows - the other model table has 150 rows. I’m going to transfer the data from these models to another one - a general summary table model. Sequentially transferring data from each model. How can I do this - to transfer data to the summary table - only by the size (number of rows) of the smallest model table? -- def file_upload_button(request): context = {} queryset_summ = Model_upload_summ.objects.all() queryset_1 = Model_upload_teplo.objects.all() queryset_2 = Model_upload_gvs.objects.all() queryset_3 = Model_upload_topgas.objects.all() datetime_1 = [d.datetime for d in queryset_1] datetime_2 = [d.datetime for d in queryset_2] datetime_3 = [d.datetime for d in queryset_3] numbers_1 = len(datetime_1) numbers_2 = len(datetime_2) numbers_3 = len(datetime_3) if numbers_1 <= numbers_2 and numbers_1 <= numbers_3: # save numbers_1 (rows of queryset Models) into queryset_summ or Model_upload_summ elif numbers_2 <= numbers_1 and numbers_2 <= numbers_3: # not active if first condition (above) id done elif numbers_3 <= numbers_1 and numbers_3 <= numbers_2: # not active if first condition (above) id done
