How can I set up my unread message counter with my models?
So I am attempting to set up an unread message counter through a simple tag and get that in my template. Now, I'm running into a problem where a message that's sent to another user is showing up as 'unread' from my user even though it's being sent to the other user. I obviously only want messages that are sent to only MY user to be shown as unread. I'm not sure if I need to add another field to my InstantMessage model such as 'receiver' or if there's someway I can check user against request.user in my unread_messages_counter.py. unread_messages_counter.py register = template.Library() @register.simple_tag def unread_messages(user): return user.sender.filter(viewed=False).count() models.py/InsantMessage and Conversation class Conversation(models.Model): members = models.ManyToManyField(settings.AUTH_USER_MODEL) class InstantMessage(models.Model): sender = models.ForeignKey(settings.AUTH_USER_MODEL, related_name= 'sender',on_delete=models.CASCADE ) conversation = models.ForeignKey(Conversation, on_delete=models.CASCADE) message = models.TextField() date = models.DateTimeField(verbose_name="Data creation",default=timezone.now(), null=False) viewed = models.BooleanField(default=False, db_index=True) def __unicode__(self): return self.message -

Django, how to set inline formset factory with two ForeingKey?
I have create a code that works perfectly except for one little problem. I have created an inline formset factory utilizing two models: Lavorazione and Costi_materiale. class Lavorazione(models.Model): codice_commessa=models.ForeignKey(Informazioni_Generali, ) numero_lavorazione=models.IntegerField() class Costi_materiale(models.Model): codice_commessa=models.ForeignKey(Informazioni_Generali) numero_lavorazione=models.ForeignKey(Lavorazione) prezzo=models.DecimalField() After I have created the inline formset facotry as the following: CostiMaterialeFormSet = inlineformset_factory( Lavorazione, Costi_materiale, form=CostiMaterialeForm, fields="__all__", exclude=('codice_commessa',), can_delete=True, extra=1 ) But I have in Costi_materiale two ForeignKey, instead in the form the formset recognise only numero_lavorazione and not also codice_commesse. I want that the formset set in the first model the codice commesse and lavorazione fields and subsequently in the inline formset the other fields. In other word: How can I set two ForeignKey in a inline formset factory? -
Django all-auth - Social login - Facebook - Pass without requesting email
So I must be missing something, I've looked for similiar questions and tried their solutions like overhere (Django allauth, require email verification for regular accounts but not for social accounts) I would like to let users interact with my webapp without requesting their e-mailadres after logging in with their social account, in this case with their facebook account. I have the following set up; settings.py ACCOUNT_EMAIL_REQUIRED = True ACCOUNT_USERNAME_REQUIRED = False ACCOUNT_AUTHENTICATION_METHOD = 'email' ACCOUNT_EMAIL_VERIFICATION = 'optional' SOCIALACCOUNT_EMAIL_REQUIRED = False SOCIALACCOUNT_EMAIL_VERIFICATION = 'optional' At the moment, whenever someone tries to login with their facebook account, they get redirected to the signup form requesting for their email address. Even though I'm using email as a authentication method for regular signups, this should not be necessary for social signups am I right? Best regards, Kevin -

How can I unittest get_context_data() of a ListView in Django?
I tried to write a unittest for a ListView in Django 3.0.5. I need to check the data included in the context. The Application is running for this view, so error in implementation is not likely.

Django TabularInline with custom inner formset
In the Django admin I have a TabularInline (WhitholdingModel) form that has three attributes, one of them is a Model itself (CIIUModel). I want to have three different choiceFields mapping an attribute of the CIIUModel. If the user selects one field, the other should be filtered to the ones that have that attribute value. So, for example, if the first choiceField is city, and I select X city, the second choiceField must only contains values whose city is X. Besides that, I'm trying the choicefields to be stacked one below other. I have tried with formset but with no luck by now. How can I accomplish this? This is the layout I'd like to have. P.S: I'm trying not to have to handle html, so if it can be accomplished with only Python would be excelent! -

The custom domain in my django app deployed with heroku doesn't work well
I deployed my first django application with heroku. I followed the procedure to add a custom domain ( example.com) inserting it in settings in ALLOWED_HOSTS and adding the custom domain in the heroku page. If I use the custom domain I can see the page but if I go in the subpages ( for example with the heroku domain app.herokuapp.com/subpage1) it doesn't add nothing to the URL but remains always example.com instead of example.com/subpage1. How can I fix it? -

for object in objects add foreignkey field bulk django
So I have this AppUser model and I want to create a send_notification function that after sending a notification to mobile via firebase SDK I want it to be added to every AppUser object as ForeignKey. Think of it like every user has notification history. The main question is how do I implement it? Which path would you take if you would write this? class AppUser(TimeStampedModel): ....... notifications = models.ForeignKey( "UserNotifications", on_delete=models.CASCADE, null=True, blank=True ) ........ I tried to write something like this for test purpose from django.utils import timezone def send_notifications(request): notification = { "title": "test title", "data": "test body", "read_date": timezone.now, "date": timezone.now, } AppUser.objects.all().update(notifications?????) -
Repeate same data in different tables OR colect data from different tables in a database
What is the best practice while coding with Django: repeate same data in different tables in a database OR do not repeat and collect them in different tables? See the example below: table1 categories column0 id column1 category table2 register column0 id column1 category.table1 column2 sales_price column3 photo table3 purchases column0 id column1 id.table2 column2 photo.table2 I'm wondering what is the best: a) Include column2 in table3 and be able to extract all information from this table b) Do not include column2 in table3 and get the photo information from column3 in the table2. Thank you! -
Django template loader cannot find template after moving to another app
I'm sure you've solved a lot of similar problems already. I decided to split old_app to new_app, so: old_app will keep Models and will be handling REST (new feature) new_app will display 'regular' views (which are all class-based btw) AND will continue to utilize old_app.models for that. In order to do that I've: splitted urls.py fixed .htmls, so now they're pointing to new_app:all_items added an entry to INSTALLED_APPS moved (and renamed) whole old_app/templates/old_app directory to new_app/templates/new_app And now, I'm getting TemplateDoesNotExist because it tries to find it in new_app/templates/old_app/modelname_list.html instead of new_app/templates/new_app/modelname_list.html What I noticed is that it works, when I add option in class derived from ListView, by explicitly giving the directory: template_name = 'new_app/modelname_list.html' (new_app.views) Why it keeps tracking old directory instead of new? -

How do we print django models object value?
Hello, everyone! So, I create models in models.py file of my django project and controllers in views.py . I wrote a function called register(request) that add a new user to my database and another called login(request) that verifies if the datas sent by the user are in my db to log him in. Brief, the problem is when I want to print the user's first name in my template, it shows to me the object in string ... Here is the login(request) function: def login(request): title = 'Connexion' if request.method == 'POST': email_sent = request.POST['email'] password_sent = request.POST['password'].encode('utf-8') global isConnected user = Users.objects.filter(email = email_sent) if user and bcrypt.checkpw(password_sent, user[0].password): if isConnected in request.session: isConnected = request.session['isConnected'] return redirect('http://localhost:8000/', {'isConnected':isConnected, 'first_name':user[0].first_name, 'last_name':user[0].first_name}) else: request.session['id'] =user[0].first_name request.session['first_name'] = user[0].first_name request.session['last_name'] = user[0].first_name request.session['phone'] = user[0].first_name isConnected = True return redirect('http://localhost:8000/', {'isConnected':isConnected, 'first_name':user[0].first_name }) else: print('Something went wrong') return render(request, 'login.html', {'title':title, 'isConnected':isConnected}) return render(request, 'login.html', {'title':title, 'isConnected':isConnected}) else: return render(request, 'login.html', {'title':title, 'isConnected':isConnected }) Here is what I represent the user's first_name variable in my template: <span class="initials" style="position: relative; top: 7px; color: white;">{{ first_name }}</span> And that is it prints to me: <django.db.models.query_utils.DeferredAttribute object at 0x0000017850EE7A00>
