Mail is not validated because I do not change my username
I have a form that takes "username" from the User model and my own "email" field. I want to change this data for the User model. At first glance everything seems to work fine, the name changes and the mail is the same. But if I only change the mail and I don't touch the username, I get an error: "A user with this name already exists. Is there any way I can make an exception for this situation? file views.py: form=UserUpdateForm(request.POST) if form.is_valid(): user=User.objects.get(username=self.request.user) user.username=form.cleaned_data.get('username') user.email=form.cleaned_data.get('email') user.save() file forms.py: class UserUpdateForm(forms.ModelForm): email = forms.EmailField(required=False) def __init__(self, *args, **kwargs): super(UserUpdateForm, self).__init__(*args, **kwargs) if 'label_suffix' not in kwargs: kwargs['label_suffix'] = '*' self.fields['username'].widget = forms.TextInput(attrs={'class':'input-text'}) self.fields['email'].widget = forms.EmailInput(attrs={'class':'input-text'}) class Meta: model = User fields = ("username","email",) def clean_email(self): cleaned_data = super(UserUpdateForm,self).clean() email=cleaned_data.get('email') return email -

If statement in Django views
I have followed an ecommerce tutorial by Dennis Ivy in Django (Python). I want to expand on the project by adding product categories. So the idea is that every product has a dropdown menu (models.py) CATEGORIES = ( ('code','CODE'), ('books', 'BOOKS'), ('computer','COMPUTERPARTS'), ('other','OTHER'), ) category = models.CharField(max_length=15, choices=CATEGORIES, default='code') The store.html shall only render products from a given category. If I type 'localhost/code' in my browser it shall only display the items that have the category: 'code'. Currently it just displays everything, when I just goto 'localhost/'. I have thought about making a urlpattern for each individual category, but I think it will get messy pretty quickly. I have a function called store in views.py def store(request): data = cartData(request) cartItems = data['cartItems'] order = data['order'] items = data['items'] products = Product.objects.all() context = {'products':products, 'cartItems':cartItems} return render(request, 'store/store.html', context) Is there a way to return only a specific category -or to return something else than objects.all()? products = Product.objects.all() The store.html looks like this: {% for product in products %} <div class="col-lg-4"> <img class="thumbnail" src="{{product.imageURL}}"> <div class="box-element product"> <h6><strong>{{product.name}}</strong></h6> <hr> {{product.about}}<br><br> <button data-product="{{product.id}}" data-action="add" class="btn btn-outline-secondary add-btn update-cart">Add to Cart</button> {{product.category}} <h4 style="display: inline-block; float: right"><strong>${{product.price}}</strong></h4> </div> </div> {% … -
Django Orm Compare to same model querysets

Add identifier only if there is a conflict for slug
I have a slug customization, It provides to create slug from title automatically. Here is my code, #models.py from django.db import models from django.urls import reverse from django.template.defaultfilters import slugify class Blog(models.Model) title = models.CharField(max_length=200) slug = models.SlugField(blank=True) def get_absolute_url(self): return reverse('school', kwargs={'slug':self.slug}) def save(self, *args, **kwargs): if not self.slug: self.slug = slugify(self.name) return super().save(*args, **kwargs) #admin.py class BlogAdmin(admin.ModelAdmin): list_display = ('title') prepopulated_fields = {'slug': ('title',)} admin.site.register(Blog,BlogAdmin) #urls.py from django.urls import path from .views import * urlpatterns = [ path('blog/<slug:slug>', entry.as_view(), name='entry'), ] If I make Slug as unique=True, when blog titles are the same(It could be same), slugs should be changed manually. I don't want this. I want to add identifier with numbers but only if there is conflict. The scenario I want is as follows, Lets assume that, Admin creates a blog, blog title is "London travel guide" -> This is the first time created blog with this title. so slug is "london-travel-guide" Second time admin creates a blog with title as "London travel guide" slug should be "london-travel-guide-1" Third time, slug should be "london-travel-guide-2" and so on. How can i implement this, thanks for help. -
URL Pattern with Primary Key not working properly
Need help with the regex in urls. I'm building a different app, not the one shown in the lecture above. To relate to my case with the lecture, School is Clients, and Students is categories. In urls.py file, from url_patterns : url(r'^(?P<pk>[-\w]+)/$', views.DetailClientList.as_view(), name='Detail_Client_List'), This work correctly, with the address being http://127.0.0.1:8000/App1/cli1/, where cli1 is a Clients table primary key (one of the records). But when I put the line below in url patterns (instead of the above) url(r'^<str:pk>/$', views.DetailClientList.as_view(), name='Detail_Client_List') I get the following error (same error for int:pk): Page not found (404) Request Method:GET Request URL:http://127.0.0.1:8000/App1/cli1/ The resulting URL is the same in both cases described above. So where am I going wrong here. I'm guessing its an issue with the url pattern regex (although resulting URL is the same?). Please help. TIA! -
There should be an error here, but does'nt
i'm following the Django's tutorial for first app, and in the Part 5 they say: Different error? If instead you’re getting a NameError here, you may have missed a step in Part 2 where we added imports of datetime and timezone to polls/models.py. Copy the imports from that section, and try running your tests again. But i not missed nothing, i write line by line, and i not received the expected message. I put my code below, if someone with more experience can help me to understand why i not receive the error message, i'll thank you ( the word appreciate and its meaning is very strange uhh). my_project/project/polls/model.py import datetime from django.db import models from django.utils import timezone class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') def was_published_recently(self): return self.pub_date >= timezone.now() - datetime.timedelta(days=1) def __str__(self): return self.question_text class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) votes = models.IntegerField(default=0) def __str__(self): return self.choice_text my_project/project/polls/tests.py import datetime from django.test import TestCase from django.utils import timezone from .models import Question class QuestionModelTests(TestCase): def test_was_published_recently_with_future_question(self) time = timezone.now() + datetime.timedelta(days=30) future_question = Question(pub_date=time) self.assertIs(future_question.was_published_recently(),False) -

Resend failed web socket messages django
I have setup django channels with redis: CHANNEL_LAYERS = { "default": { "BACKEND": "channels_redis.core.RedisChannelLayer", "CONFIG": {"hosts": [(REDIS_HOST, REDIS_PORT)]}, } } On connection to my websocket channel I update a row in my database for the corresponding user/team - socket_channel - with the websocket channel_name. team.socket_channel = self.channel_name team.save() On disconnection, I remove this from the row. I have created a handler for my Team model: def send_ws_message(self, message: WSStruct) -> bool: channel_layer = get_channel_layer() if not self.socket_channel: logging.error(f"{self.username} is not connected to a socket") # TODO store message in redis return False async_to_sync(channel_layer.send)(self.socket_channel, message.dict()) return True I am wanting to add two pieces of functionality: When the team connects to the channel again they will receive all messages that were not received because of the team not actually being connected to the websocket (the TODO above). A sort of ack that the client actually received the websocket message and if not will store for sending on reconnection/ping-pong. I am assuming the best way to do this is with a redis store? But I would also like to not reinvent the wheel here as imagine this is a fairly common design? Any advice would be greatly appreciated. -
