How to revert objects using django-simple-history
In this answer, the user provided the following HistoricForm to revert an object to an earlier instance of the object: class HistoricForm(object): def __init__(self, *args, **kwargs): self.history_id = kwargs.pop('history_id', None) instance = kwargs.get('instance') if instance and self.history_id: kwargs['instance'] = self.get_historic_instance(instance) super(HistoricForm, self).__init__(*args, **kwargs) def get_historic_instance(self, instance): model = self._meta.model queryset = getattr(model, 'history').model.objects historic_instance = queryset.get(**{ model._meta.pk.attname: instance.pk, 'history_id': self.history_id, }).instance return historic_instance I have added this code to my models.py file, but I am now stuck about how to actually revert a model. The user stated, You can revert by showing the historic instance and save (this way you will post your historic data). I created a view and a corresponding template that shows all the versions of a given object in its history using django-simple-history. However, I don't understand how to allow the user to revert to one of these versions using the above form. Can someone please provide me some guidance? -
Django ORM. How to exclude old data?
I want to exclude unnessery old records from my queryset. I tried use annotate(Max('pc_users__created')), but this is not what i want. I think i should use 'group by' or something like that, but I can not understand how. Here's my models.py class Room(models.Model): created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) room_number = models.SmallIntegerField() def __str__(self): return f'Room №{self.room_number}' class UserProfiles(models.Model): created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) name = models.CharField(max_length=100) def __str__(self): return f'{self.name}' class Pc(models.Model): created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) title = models.CharField(max_length=100) ram = models.SmallIntegerField() cpu = models.CharField(max_length=20) gpu = models.CharField(max_length=20) def __str__(self): return f'{self.title}' class PcUsers(models.Model): created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) pc = models.ForeignKey(Pc, on_delete=models.PROTECT, related_name='pc_users') user = models.ForeignKey(UserProfiles, on_delete=models.PROTECT) def __str__(self): return f'{self.pc}: {self.user}' class PcRooms(models.Model): created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) pc = models.ForeignKey(Pc, on_delete=models.PROTECT, related_name='pc_rooms') room = models.ForeignKey(Room, on_delete=models.PROTECT) def __str__(self): return f'{self.pc}: {self.room}' and views.py: from myapp.models import Pc def report(request): data = Pc.objects.values( 'id', 'title', 'pc_users__user__name', 'pc_rooms__room__room_number' ) return render(request, 'report.html', {'data': data}) Also here is my data from admin site I want exclude all repetitive records and keep all newest records.

Django: form not validating
I had a form working perfectly right, but now it doesn´t work anymore. Can´t detect what I had changed that is affecting this. The form with it´s inital data is showed correctly in the template, but for some reason it´s not validating in the view. The rest of the forms are working without problems.

Return Serialized data without storing one field in the database?
Assuming I have a model as follows: class MyModel(models.Model): value = models.TextField(null=True) And I have a serializer as follows: class MyModelSerializer(serializers.ModelSerializer): id = serializers.IntegerField(required=False, allow_null=True) class Meta: model = MyModel fields = ('value') Is it possible to pass a value to the serializer that is not saved in the database, just passed back in the exact same position? So if I send the application { 'value': 'true', 'uuid': '123' } It would return { 'id': 1, 'value': 'true', 'uuid': '123' } -
Communication between Python desktop app and remote Django server
Would it be possible to have two-way communication between a Python desktop application and a Django server, and if so what would be the best method? The Django server would host a page that allows a user to send commands to the desktop application and view the status of the desktop application. The desktop app would need to send status updates. I've looked into Channels with Django and the client would just need to create a TCP socket connection to send its data. I don't quite know how Django would send the required data to the client. Thanks for any help or input. -
Fixing Django-Haystack Exact Query
I'm trying to fix my Django-haystack search results to only return outputs of the exact query. The principal usecase is that a user enter is destination and get only the results that matches this given place. But the problem I have now is that when a user try for example, a query for "Mexico", the search results also returns information in "Melbourne" which is far from being user-friendly and accepted. What I've tried so far but still not working: My forms.py from haystack.forms import FacetedSearchForm from haystack.inputs import Exact class FacetedProductSearchForm(FacetedSearchForm): def __init__(self, *args, **kwargs): data = dict(kwargs.get("data", [])) self.ptag = data.get('ptags', []) self.q_from_data = data.get('q', '') super(FacetedProductSearchForm, self).__init__(*args, **kwargs) def search(self): sqs = super(FacetedProductSearchForm, self).search() # Ideally we would tell django-haystack to only apply q to destination # ...but we're not sure how to do that, so we'll just re-apply it ourselves here. q = self.q_from_data sqs = sqs.filter(destination=Exact(q)) print('should be applying q: {}'.format(q)) print(sqs) if self.ptag: print('filtering with tags') print(self.ptag) sqs = sqs.filter(ptags__in=[Exact(tag) for tag in self.ptag]) return sqs My search_indexes.py import datetime from django.utils import timezone from haystack import indexes from haystack.fields import CharField from .models import Product class ProductIndex(indexes.SearchIndex, indexes.Indexable): text = indexes.EdgeNgramField( document=True, use_template=True, template_name='search/indexes/product_text.txt') … -
How to Set Rendered URL Endpoint
I know this is an easy problem, but I cannot seem to get it working properly. I recently changed the urlpatterns from mydomain.com/website/template to mydomain.com/template in my project. However, when I render pages, I am being redirected to the old pattern still. When I remove website from the URL, the page is render correctly. How can I render the page without website in the urlpattern? Would I make this change in urls.py or views.py? For the example below, I want the end result to be: mydomain.com/connectwise/search?search_query= I tried return render(request, '/search.html', context) but then the application does not recognize the URL endpoint and returns resource not found. views.py return render(request, 'website/search.html', context) urls.py (application) urlpatterns = [ path('connectwise/search', views.search_bar, name='search_bar'), ] urls.py urlpatterns = [ path('admin/', admin.site.urls), path('', include('website.urls')), ] -
Is it ever possible to delete a URL path : Django
I had in my urls.py file, url patterns for certain data processing requirements and later I realized that from among a bunch of them, one was not intended as its requirement had ceased. However, when I am trying to delete the particular line (the second pattern in the excerpt of the urls.py reproduced here), I am getting the following error at page load ('holding_list'): NoReverseMatch at /supp/holding_comp/ Reverse for 'holding_change' not found. 'holding_change' is not a valid view function or pattern name. I have checked all the references (I think) wherever the path might have been referred to (including the related template). urls.py path('supp/holding_comp/', views.HoldingListView.as_view(), name='holding_list'), ... ... path('supp/holding_comp/edit/<int:pk>/', views.HoldingUpdateView.as_view(), name='holding_change'), How do I delete the second url pattern (the one for "edit" view)? I tried to look for a similar query but failed to (may be for want of a suitable search string). Any clue will be appreciated. -
How to make swagger schema for file upload API in django-rest-framework using drf-yasg?
I am not able to find any support for making a schema for the file upload API. The Swagger UI must have a button allowing a tester to upload a file for testing purposes. I am using firebase as a database so serializers and models don't come into the picture. I am using only Django's rest framework. I have looked at drf-yasg's documentation that suggests using Operation for file upload. But It is a very abstract and obscure documentation. -

Is there a way to inherit the template of an abstract parent model class in Wagtail?
I've got an abstract Page model that defines common fields for a type of page that I then subclass to restrict the types of subpages allowed.

I want the following command: SELECT * FROM Songs INNER JOIN Artists ON Songs.PageURL = Artists.PageURL WHERE IsSingle = 1 AND Artist like 'Singer%' ORDER BY Entry_At DESC Here is my models.py from django.db import models class Artists(models.Model): artist = models.CharField(db_column='Artist', max_length=400) # Field name made lowercase. pageurl = models.CharField(db_column='PageURL', primary_key=True, max_length=400) # Field name made lowercase. albumurl = models.CharField(db_column='AlbumURL', max_length=400) # Field name made lowercase. class Meta: managed = False db_table = 'Artists' unique_together = (('pageurl', 'artist'),) class Lyrics(models.Model): lyrics = models.CharField(db_column='Lyrics', max_length=400) # Field name made lowercase. pageurl = models.CharField(db_column='PageURL', primary_key=True, max_length=400) # Field name made lowercase. albumurl = models.CharField(db_column='AlbumURL', max_length=400) # Field name made lowercase. class Meta: managed = False db_table = 'Lyrics' unique_together = (('pageurl', 'lyrics'),) class Music(models.Model): music = models.CharField(db_column='Music', max_length=400) # Field name made lowercase. pageurl = models.CharField(db_column='PageURL', primary_key=True, max_length=400) # Field name made lowercase. albumurl = models.CharField(db_column='AlbumURL', max_length=400) # Field name made lowercase. class Meta: managed = False db_table = 'Music' unique_together = (('pageurl', 'music'),) class Songs(models.Model): index = models.IntegerField(db_column='ID') # Field name made … -
How to use two different templatetags in two apps in django?
Say I have a project and two registered apps. Inside my apps I created templatetags package with custom tags that I want to use in corresponding html templates: Project | | --App1 | |----templatetags | |----custom_tags.py |----__init__.py --App2 | |----templatetags | |----custom_tags.py |----__init__.py And it looks like django sees only one templatetags folder. I use {% load custom_tags %} in html templates in both apps. When there is only one templatetags folder then corresponding custom tags work (so there is no error in custom_tags.py). I tried to rename one file to eg 'custom_tags_app1' and then {% load custom_tags_app1 %} in html templates in app1, but then it throws error saying: 'custom_tags_app1' is not a registered tag library. Must be one of: . . custom_tags ... When I renamed it I tried to import 'custom_tags_app1' in the shell and it worked What am I missing here? What should I do to make it work, when they both work independently, but don't work together? -
