Creating an object of a class whose field is a set of objects of another class
In the Django model lets create a class, eg Ingredients: class IngredientsClass(models.Model): name = models.CharField('Name', max_length=50, default='') package_price = models.FloatField() package_amount = models.FloatField() supplier = models.ForeignKey(SupplierClass) price = models.FloatField() Now lets make some product from the ingredients class DishClass(models.Model): name = models.CharField('Name', max_length=50, default='') price = models.FloatField() ingredients = models.***???*** And here is a problem... In the field ingredients of an DishClass object can be different amount of ingredients from one to thousand. How do I need to set up the field ingredients? -

Automatic field filling based on user information
I want the name field to be filled automatically based on the user's information and the user cannot change it while filling the form.

Django REST framework and Vue.js "CSRF cookie not set" is occurred

is ConnectionClosedByClient exception from pika a problem
I recently upgraded to a newer version of pika and these logs started showing up where they have not been there before: User-initiated close: result=BlockingConnection__OnClosedArgs(connection=<SelectConnection CLOSED transport=None params=<URLParameters host=rabbitmq port=xxxxx virtual_host=xxxxx ssl=False>>, error=ConnectionClosedByClient: (200) 'Normal shutdown') AMQP stack terminated, failed to connect, or aborted: opened=True, error-arg=None; pending-error=ConnectionClosedByClient: (200) 'Normal shutdown' Stack terminated due to ConnectionClosedByClient: (200) 'Normal shutdown' I have looked over my changes but all I was doing before these logs showed up was to upgrade my django project libraries No changes in logic have taken place It is confusing because according to documentation this exception, ConnectionClosedByClient, is raised when "Connection was closed at request of Pika client." which is the normal behaviour? Also it says Normal Shutdown So am i safe to assume this is just a new log that is cluttering my logs and isn't an actual error because all my rabbitMQ and logs are all good and they are behaving properly as well If it is the case that it is just new logs and this exception needs to be handled for it to not appear in logs, any tips on how to do that safely as well -
Django: Track and save to db user login/logout activities
I want to log users into the database with their time when they log in or log out. I can do this if these operations are done using the login and logout functions, but I need to detect and record the logout operation when they log out by closing the browser. I used websocket for this, but websocket disconnects and reconnects when users switch pages in the project, so it is detected as logout. Is there a way to do this? I added this websocket codes to my base.html let wsProtocol = window.location.protocol === "https:" ? "wss" : "ws"; let url = `${wsProtocol}://${window.location.host}/ws/socket-server/` const markSocket = new WebSocket(url) markSocket.onopen = function(e){ markSocket.send(JSON.stringify({ 'message':'CONNECTED' })) } markSocket.onclose = function(event) { console.error("WebSocket closed:", event); }; and here is my consumer.py that connected to websocket class OnlineStatusConsumer(AsyncWebsocketConsumer): async def connect(self): await self.accept() user = self.scope['user'] status = True print("CONNECTED",user) await self.change_online_status(user, status) async def disconnect(self, close_code): user = self.scope['user'] status = False print("DISCONNECTED", user,close_code) await self.change_online_status(user, status) @database_sync_to_async def change_online_status(self, user, status): if status: active_user = ActiveUsers.objects.get_or_create()[0] if not active_user.active_users.filter(id=user.id).exists(): active_user.active_users.add(user) active_user.active_user_count += 1 active_user.save() # Kullanıcının en son oturum açma girişimini al last_login_attempt = SpecificUserLoginDiary.objects.filter(user=user).last() # Eğer kullanıcı daha önce oturum açma … -
Django logging not happening in real-time
I have a log configuration setting like the following: LOGGING = { 'version': 1, 'formatters': { 'verbose': { 'format': '[{levelname}] {asctime} {module}.{funcName}.{lineno} {process:d} {thread:d} {message}', 'style': '{' } }, 'filters': { 'filter_for_generic': { '()': 'service.logging.filters.FilterLevels', 'filter_levels': [ "INFO", "DEBUG" ] }, 'filter_for_mail': { '()': 'service.logging.filters.FilterLevels', 'filter_levels': [ "WARNING", "ERROR", "CRITICAL" ] }, }, 'handlers': { 'file_generic': { 'level': 'DEBUG', 'class': 'logging.handlers.TimedRotatingFileHandler', 'filename': path.join(BASE_DIR, 'logs', 'generic.log'), 'when': 'midnight', 'backupCount': 30, 'formatter': 'verbose', 'filters': ['filter_for_generic'] }, 'file_diagnostic': { 'level': 'WARNING', 'class': 'logging.handlers.TimedRotatingFileHandler', 'filename': path.join(BASE_DIR, 'logs', 'diagnostic.log'), 'when': 'midnight', 'backupCount': 30, 'formatter': 'verbose' }, 'mail_admins': { 'level': 'WARNING', 'class': 'django.utils.log.AdminEmailHandler', 'filters': ['filter_for_mail'] } }, 'loggers': { 'app': { 'handlers': ['file_generic', 'file_diagnostic', 'mail_admins'], 'level': 'DEBUG' }, 'jwt_validator_middleware': { 'handlers': ['file_generic', 'file_diagnostic'], 'level': 'DEBUG' }, 'django': { 'handlers': ['file_generic', 'file_diagnostic', 'mail_admins'], 'level': 'DEBUG' } }, } Let's say I am something in my code as follows: LOGGER = logging.getLogger(__name__) LOGGER.info("Hello") The generic log file gets created, but I can't see the Hello in the file.

Django DB backup and restore
I am using Postgres in my Django project. My concern is regarding database backup and restore. Let's say I have a Django model named TestModel with name as a char field in that TestModel. I have ran Django's migrations and have inserted the data into model from Frontend. Then I take backup of database using django's dumpdata command and store it into backup.json. At some point after backup, I had to delete my database, change the field name 'name' to 'machine_name' of TestModel and then I ran migrations. Now when I try to insert data by loaddata command using my earlier backup file named backup.json, it gives me error for that name field that I had changed. I tried: Django's built-in commands like dumpdata and loaddata. Third-party library django-dbbackup I need to know how this database backup and restore is carried out in production when there are changes in database schema. How can I know the changes in database schema from one backup to another and if there are changes in schema I still be able to restore my old data into new database. -

How to change the default "non_field_errors" message with Django Rest Framework

That's why I've added the "format" option, but once this option is set up (line to be uncommented in the above code), my form is no more valid: the date field becomes red when I submit the form data, but no error message is raised on the server side. The data is simply not submitted to the database. And the print you can see in the clean() function no longer returns anything related to … -

HTML CSS background image not loading
I have a background image url('home1400.jpg') from the style.css file. I have saved the image in the same folder as the style.css for debugging. /* ===== Home ====== */ .sectionHome{ width: 100%; min-height: 90vh; background-image: linear-gradient(0deg, rgba(0,0,0,0.3), rgba(0,0,0,0.3)), url('home1400.jpg'); background-position: center; background-size: cover; position: relative; display: flex; justify-content: center; flex-direction:column ; } /* ===== end food Home ====== */ I checked that the home.html reads the style.css because if I change the home1400.jpg for any url with a picture in the internet, it loads the picture in the internet. So I cannot see the image and I dont know why. I see in Chrome inspection that the image points to an static url. Is this the reason? Maybe my Django statics are wrongly set? Any idea what may be going on? I have checked other SO questions but still not working. -

Hi I am new to Django and due to time constraints i am making a personal_project on the go.I have been able to set upa login page and some forms to fetch the data going through videos and tutorial. The issue i am facing now is that for a location model.If i insert same data multiple times it is creating a new row in My DB. What would be the correct way to prevent it should i update my Db model logic or Is there a view level validation that i can implement for same? My Current Model includes User(Default User Model), Agency and Lcoation Models And Each user can create multiple agencies but each agency can have one or more location but not at the same place.Below is how i have set it up is there any to identify if the string is same? One way i though was that i Should query and concat all the fields to lower from Location model before saving it and compare it with the new data and only if its different i should update it .Is it a efficient/valid way to do it? Here is the model i am using Any Advice … -
Django Bootstrap modal forms missing csrf token
I'm using django bootstrap modal forms for login and signup popups but they're missing csrf tokens, i get "CSRF token from POST incorrect." error when signing up or logging in. I have {% csrf token %} in my html templates so that's not the problem. I've seen lots of answers to this problem with views reconfigurations (adding method decorators and form to render context) but since i'm using class-based view from bootstap modal forms documentation example I can't repeat such solutions. My views look like this: class CustomLoginView(BSModalLoginView): authentication_form = CustomAuthenticationForm template_name = 'login.html' success_message = 'Success: You were successfully logged in.' extra_context = dict(success_url=reverse_lazy('home')) class SignUpView(BSModalCreateView): form_class = CustomUserCreationForm template_name = 'signup.html' success_message = 'Success: Sign up succeeded. You can now Log in.' success_url = reverse_lazy('home') I've tried rewriting them with methods like this: class SignUpView(BSModalCreateView): def signup_view(request): form = CustomUserCreationForm() if request.method == "GET": return render(request, 'signup.html', context={'form':form}) if request.method == "POST": data = request.POST if form.is_valid(): user = form.save(False) user.set_password(user.password) user.save() return redirect('home') but then forms stop working. Also, I've tried adding CsrfExemptMixin from django-braces but that didn't work either. The only solution that worked is disabling csrf checks completely but I really want to keep them … -
Django - fill in a field based on what the user enters for another field
I am trying to have a field fill in automatically based on what the user enters for another field. You will see below that there is a Choice field called 'typeofacct' and there is another field called 'mintoopen'. One of the options for 'typeofacct' is Everyday Business and there are 4 other options as well. For example, if the user selects Everyday Business as the option for the 'typeofacct' field, I would like to have the 'mintoopen' field filled in with '$100' (a string). Below are my files: forms.py class WaiveForm(forms.Form): header = forms.CharField( widget=HeaderWidget(attrs={'class': 'my-css-class'}), initial='Fee Waive Worksheet', required=False, label='' ) businessname = forms.CharField(max_length=50, label='Business Name') acctnum = forms.IntegerField(label='Business Account Number') annualreviewdt = forms.DateField(label='Annual Review Date', initial=(today + relativedelta(years=1)).strftime('%m/%d/%Y'), disabled=True, required=False) effectivemonth = forms.ChoiceField(choices=effectiveMonthChoice, label='Effective Month') typeofacct = forms.ChoiceField(choices=typeOfAcctChoice, label='Type of Account') # Table mintoopen = forms.ChoiceField(required=False, choices=minToOpenOptions) class SnippetForm(forms.ModelForm): class Meta: model = Snippet fields = ('businessname', 'acctnum', 'annualreviewdt', 'effectivemonth', 'typeofacct', 'mintoopen') models.py class Snippet(models.Model): businessname = models.CharField(max_length=50) #acctNum = models.IntegerField(max_length=17) acctnum = models.PositiveIntegerField(primary_key=True, validators=[MaxValueValidator(99999999999999999)]) annualreviewdt = models.DateTimeField(default=today) effectivemonth = models.CharField(choices=effectiveMonthChoice, max_length=2) typeofacct = models.CharField(choices=typeOfAcctChoice, max_length=1) # Table mintoopen = models.CharField(max_length=20, blank=True, choices=minToOpenOptions, default=typeofacct.formfield()) def __str__(self): return self.businessname, self.acctnum, self.annualreviewdt, self.effectivemonth, self.typeofacct, self.mintoopen def mintoopen_func(self): return minToOpenArray[int(self.typeofacct)] def … -
