Add scroll wheel to Ckeditor 5 text editor django
I am quite new to using django. I want to add a rich text editor to my webapp and I saw a tutorial on how to do so using "django-ckeditor-5". I followed these steps: https://pypi.org/project/django-ckeditor-5/ and the editor works fine and everything however, it keeps expanding with the the text, so it just goes of the screen after a while. Is there a way to stop this behavior, and instead add a scroll wheel to the side of the editor so users can use that to see the entire text? I was also wandering how I can install plugins to the editor since I know it's possible but i'm not really sure how. Here is my ckeditor config in the settings.py file: customColorPalette = [ { 'color': 'hsl(4, 90%, 58%)', 'label': 'Red' }, { 'color': 'hsl(340, 82%, 52%)', 'label': 'Pink' }, { 'color': 'hsl(291, 64%, 42%)', 'label': 'Purple' }, { 'color': 'hsl(262, 52%, 47%)', 'label': 'Deep Purple' }, { 'color': 'hsl(231, 48%, 48%)', 'label': 'Indigo' }, { 'color': 'hsl(207, 90%, 54%)', 'label': 'Blue' }, ] CKEDITOR_5_CONFIGS = { 'default': { 'toolbar': ['heading', '|', 'bold', 'italic', 'link', 'bulletedList', 'numberedList', 'blockQuote' ], }, 'extends': { 'blockToolbar': [ 'paragraph', 'heading1', 'heading2', 'heading3', '|', … -
Custom logger Formatter in Python
I need to use 2 different handlers, one for Elasticsearch and the other for Django. The Elasticsearch handler has already custom formatter (json-like), and is set to ERROR level. I need to pass extra args in order to create indexes in Kibana. The Django logs needs a different formatting: '[%(asctime)s] %(name)s %(levelname)-8s --> %(message)s'. But for the ERROR level I need to take care of the extra, because the message will be: f"[{pid}] {func}() - {msg} - {tb} - [{exc_name} - {exc_args}]" For the INFO i need only f"[{pid}] {func}() - {msg}" So I created a Custom Formatter Class, and it works but: I can not find a way to pass the fmt in order to add asctime and name (package.module). The LogRecord doesn't have by default them. LOG_BASE_PATH = BASE_DIR / 'logs/' LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'precise': { '()': utils.DjangoCustomFormatter("[%(asctime)s] %(name)s %(levelname)s: %(message)s"), # 'format': '[%(asctime)s] %(name)s %(levelname)-8s --> %(message)s', }, 'ecs': { '()': 'ecs_logging.StdlibFormatter', }, }, 'handlers': { 'file_django': { 'class': 'logging.handlers.RotatingFileHandler', 'filename': LOG_BASE_PATH / 'django.log', 'formatter': 'precise', 'level': 'INFO', }, 'file_ecs': { 'class': 'logging.handlers.RotatingFileHandler', 'filename': LOG_BASE_PATH / 'test.log', 'formatter': 'ecs', 'level': 'ERROR' }, }, 'loggers': { 'multi_logger': { 'handlers': ['file_ecs', 'file_django'], 'level': … -

Django ORM: LEFT JOIN condition based on another LEFT JOIN
I'm using Django 4.0 and PostgreSQL (13.7) as the backend (upgrading would be possible if its required for a solution) I have two models: Cat and Attribute. The Attribute holds generic key-value pairs describing Cat instances. Cat table: PK name 1 Wanda 2 Aisha 3 Thala Attribute table: PK cat_id key value 1 1 size 10 2 1 age 5 3 2 size 7 4 2 intelligence 75 5 2 children 3 6 3 intelligence 60 7 3 age 9 I'd like to select different attribute values depending on conditions of other attributes for all instances, e.g.: Get size of a Cat if its age is greather than 4 or it has more than 2 children - or if there is no match, get age if intelligence is over 50. Well, the example here contains random attributes and numbers and does not make any sense, but in my application's world the conditions can be overly complex including several recursive AND, OR, EXISTS and NOT conditions. My query would be: SELECT DISTINCT(cat.id), cat.name, COALESCE( result1.key, result2.key ) as result_key COALESCE( result1.value, result2.value ) as result_value FROM cat -- first condition LEFT OUTER JOIN attribute cond1 ON ( cat.id = cond1.cat_id AND … -
create a new model instance automatically in django
I am creating a django + react.js project. I have integrated social auth for google using django social auth. I am able to get the django access token and in the admin panel I can see a new User instance is getting created. However I have a UserProfile model which has a one-to-one relation with the User model and there no new instance is getting created. Following is my model class for UserProfile. class UserProfile(models.Model): user = models.OneToOneField(User,on_delete=models.CASCADE) userName = models.CharField(max_length=26,unique=True) email = models.EmailField(max_length=254,unique=True) profilePhoto = models.ImageField(default="/default.png") rank = models.CharField(max_length=26,default="Novice") def __str__(self): return self.userName My question is, Is there any way that I could automatically create a new instance for UserProfile just whenever a new User instance is getting created. -
Django Models: Different fields in a form depending on a selected option from a selected list
One table has a choices select list, specialization (rocket engines, navigation software, or airports) The other table(s) should create different Forms which have different classes, (I mean college study program classes) and therefore different fields in the Form, depending on what was selected on the other table. Should I create several models, one for each specialization? so that each has different study program classes? How can I make it so that upon having chosen a specialization, the corresponding model is activated and launches me the correct Form? This is my timid visualization, but I have no idea whether that is the right approach or even how to implement that code. So far 4 days and can't get my head around it. I have seen this: Django: Switch a form in template depending on choice field but still can't come full circle. -

function on entering admin list view
I have an admin list view, that for every row calls an external API and therefore becomes costly. So I am looking for a way to make the call once on entering the admin list view: @admin.display(description = "foo") def some_action(self, obj): return do_some_expensive_call(obj) I want to turn this into: def run_once(self): self.results = {} self.results[key] = some_expensive_list_call() @admin.display(description = "foo") def some_action(self, obj): return self.results[obj] Is there a method that should be used? -
Django: connection of LoginView with template fields
I created a combined registration and login form that is linked to the LoginView, but I ran into a problem relating the fields in the form to the LoginView mechanism (it does not use them). Can anyone suggest if it's possible to use custom template styling instead of using the standard approach with unstyled {{form.username}}, {{form.password} } and the like? Thanx!

In my flask web application, I am trying to update user's credits immediately after user has made payment through paypal. To make it secure, I want to make sure that user doesn't modify the amount of payment. I also want to ensure that I credits to the correct user who made the payment. This requires me to send a 'custom' variable assocaite to the user who is going to make the payment. And on the payment is captured/successed, the custom variable can be read back from the payment confirmation, so that I can identify which user made the payment. After that, I can update database and update user credit.

How can I customize the data for a serializer in Django Rest Framework with the POST request data and function generated data?
I have created an APIView that handles a POST request in DRF. I need the POST request to save data in my database based on one of my models: Model class Card(models.Model): game = models.ForeignKey(Game, on_delete=models.CASCADE) image_numbers = jsonfield.JSONField() The game parameter is an integer that will be received from the client application, and the image_numbers field is a list that I want to serialize to be stored as a json object. Here is my serializer: class CardSerializer(serializers.ModelSerializer): class Meta: model = Card fields = ( 'game', 'image_numbers' ) Here is my view class CardsView (APIView): permission_classes = (IsAuthenticated, ) def generate_combinations(request): L = [i for i in range(1, 64)] List = random.choices(L, k = 16) return List def get(self, request, *args, **kwargs): qs = Card.objects.all() serializer = CardSerializer(qs, many=True) return Response(serializer.data) def post(self, request, *args, **kwargs): #I asume this is the line I should modify serializer = CardSerializer(data = request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data) return Response(serializer.error) Whenever the POST request is received with the game parameter, I want to execute the generate_combinations function and store both the game(received with the request) and the generated_combinations result, which is a list. I'm lost on how to structure the data for …
