serializer showing name of model
I want to serialize data from nested queryset: I have working code but output from serializer showing too many data. I want hide this for security reason. example output: (...) "gallery": "[{"model": "mainapp.imagesforgallery", "pk": 1, "fields": {"user": 1, "image": "uploads/2022/8/6/drw/Adapta-KDE-theme_JOgL4kO.webp", "thumbnail": ""}}]" (...) this is models.py class ImagesForGallery(models.Model): user = models.ForeignKey(UserProfile, null=True, blank=True, on_delete=models.CASCADE) image = models.ImageField(upload_to=user_directory_path, blank=True, null=True) thumbnail = models.ImageField(upload_to='uploads/', blank=True, null=True) def __str__(self): return 'User: {} || Image: {}'.format(self.user, self.image) class Gallery(models.Model): project = models.ForeignKey(Projects, null=True, blank=True, on_delete=models.CASCADE) project_gallery = models.ManyToManyField(ImagesForGallery, blank=True, related_name='project_gallery') def __str__(self): return '{}'.format(self.project) This is my view class HomeView(viewsets.ModelViewSet): serializer_class = ProjSerializer queryset = Proj.objects.all() def list(self, request, *args, **kwargs): response = super(HomeView, self).list(request, args, kwargs) gal = Gallery.objects.all() for d in response.data: for g in gal: if d['uuid'] == str(g.project.uuid): qs = g.project_gallery.get_queryset() serialized_obj = serializers.serialize('json', qs) d['gallery'] = serialized_obj return response This code compares the project model to the photo gallery model. If uuid is correct, include this gallery in the project and send json. I'm not sure the code is efficient and safe. The question is how to modify the code so that it does not show the model name. -

I can't solve this problem myself, I have the following code: urls.py re_path(r'^category/(?P<hierarchy>.*)$', show_category, name='category'), I tried different things, settled on two options after the comment "# No category, show top-level content somehow" views.py def show_category(request, hierarchy=None): hierarchy = (hierarchy or "").strip("/") # Remove stray slashes if hierarchy: category_slug = hierarchy.split('/') parent = None for slug in category_slug[:-1]: parent = Categories.objects.get(parent=parent, slug=slug) category = Categories.objects.get(parent=parent, slug=category_slug[-1]) else: category = None if category: return render(request, 'shop/categories.g.html', {'instance': category}) # No category, show top-level content somehow # categories = Categories.objects.all() category = Categories.objects.filter(parent=None) return render(request, 'shop/categories.g.html', {'instance': category}) The problem is that the path /category/window-and-door opens the required category.

Django creating multiple groups with post_save
I need to auto-create several groups with a post_save signal. I almost have this working however, as a novice, I can't get the syntax right. When I use the code below, instead of two groups, I get one group with the name ('manager', 'employee'). How would I change this to add two groups - manager and employee? # autocreate basic employee groups when new company is created @receiver(post_save, sender=Tenant) def create_basic_group(sender, created, **kwargs): if created: # Get or create group new_group, created = Group.objects.get_or_create( name=('manager', 'employee')) -
Django, how to save a randomly generated variable for the next session after POST method
I have an integer in Views.py which is generated randomly. I send it to Index.html: return render(request, 'index.html', {'number':number}) Then I have a simple form in forms.py class AForm(forms.Form): information = forms.CharField(label='Your answer', max_length=100) And this form in Index.html with POST method: <form action="{% url 'index' %}" method = POST> {% csrf_token %} {{ form }} <input type="submit" value="Submit"> </form> which leads to the same page and function. And I want to return via this POST method that number which I previously sent, because now it is already another, taken randomly, because it is the same function. But I already need the previous one. In other words I generate a random number and I need to save it for the next loading, after POST Method. I would even not send that number anywhere if it is possible. Is there a simple, elegant way to do it? I've read about sessions in Django, probably it is the way, but is there an easier way? Thanks. -

PyCharm: Cannot connect to postgres-db in docker container

Does anyone might know what I'm doing wrong or maybe had the same problem? Thanks for your help and have a great weekend! -

How to loop websocket events in django in a roulette game
Hello fellow programmers, I'm currently using Django with WebSockets to create a replica close to https://bloxflip.com/roulette or any kind of online synchronized roulette you can have that involves multiple bets from all different players. I am at this stage attached image, and I'm trying to create a backend loop that will run between states (Waiting for bets, Calculating hashes, Rolling, Restarting), the only solution I got is using workers from Celery that will loop it on a Redis server. I wonder if there is any other solution that can help me make this loop in the backend so I can send it to the frontend with WebSockets. Let me know what other method i can use or if i can improve my actual code. consumers.py class RouletteConsumer(WebsocketConsumer): def connect(self): self.room_group_name = 'roulette' async_to_sync(self.channel_layer.group_add)( self.room_group_name, self.channel_name ) self.accept()` current_state = states[0] self.send(text_data=json.dumps({ 'type':'current_state', 'current_state': current_state })) def receive(self, text_data): text_data_json = json.loads(text_data) bet_data = text_data_json['bet_data'] async_to_sync(self.channel_layer.group_send)( self.room_group_name, { 'type':'send_bet', 'bet_data': bet_data, } ) def send_bet(self, event): bet_data = event['bet_data'] self.send(text_data=json.dumps({ 'type':'bet', 'bet_data': bet_data })) def current_state(self, event): state = event['current_state'] self.send(text_data=json.dumps({ 'type':'state', 'current_state': state })) -

Store the primary key but display the name of an instance in Django Forms
I created a form through which the user can send an email to customers. I wanted to create a UI where the user can select a customer from the list of customers and automatically after clicking the customer, the email field is updated(i.e., the customer's email). I have done this before and the Foreign Key relation works the best but in this case, I think there is no need to create a different app for Email support and then give the foreign relations, etc. forms.py: class EmailForm(forms.Form): customer = forms.CharField(widget=forms.Select) email = forms.CharField(max_length=100) subject = forms.CharField(max_length=100) attach = forms.FileField() message = forms.CharField(widget = forms.Textarea) def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['customer'].widget.choices = [(i.name, i.name) for i in Customer.objects.all()] email.html: {{ customer_data|json_script:"customerdata" }} <script type="text/javascript"> var customerdata = JSON.parse(document.getElementById('customerdata').textContent); document.getElementById('id_customer').onchange = function(event){ var cust = customerdata.find(({customer_id}) => customer_id == event.target.value); document.getElementById('id_email').value = cust && cust.email ? cust.email : ""; }; I am passing the Customer data to the email.html using JSON but I am not able to assign the email to the appropriate field because id_customer returns a String, i.e., The customer name and not the customer_id as I want.

Django.urls reversing urls through multiple url pattern lists within one app
I have a url.py inside my project which includes the following urls.py (belongs to my app). urls.py from django.urls import path,include from .views import Index, Foo bar_urlpatterns = [ path('foo/', Foo.as_view(), name='foo'), ] urlpatterns = [ path('', Index.as_view(), name='index'), path('bar/', include(bar_urlpatterns)),] I'm trying to outsource the subpaths of a path. The docs says the function include can include a pattern_list and when i call the url"http://myurl/foo/bar" directly, this seems to hold true. I can also load the view via ajax directly when i give it the string. But when i try to use the reverse {%url 'foo'} url template tag this throws: Uncaught SyntaxError: Invalid regular expression flags(at ...) Doing the same thing with non-outsourced url patterns works perfectly fine for me. The html elements where i use the function: <a onclick="load_tab_view({% url "foo" %})">Foo</a> <div id="tab_view_replaceable"></div> js (works fine with my other views) function load_tab_view(url){ replace_id = 'tab_view_replaceable'; $.ajax({ url: url, type: 'GET', dataType: 'html', success: function(data){ $('#'+replace_id).html(data); } }); } Is there a way in which im still able to outsource my subpaths and make use of the reverse url template tag? (I dont want to create a new app for bar) -
