How Can I Get A Dictionary Value From Python?
I was trying to convert a look up today to a data dictionary...for performance reasons... It's almost working...Except that it's duplicating the entries on my output... Here is my code in question... class Calendar(HTMLCalendar): def __init__(self, year=None, month=None, user=None): self.user = user self.year = year self.month = month super(Calendar, self).__init__() # formats a day as a td # filter events by day def formatday(self, day, requests): requests_per_day = DailyPlannerRequest.objects.filter(Q(created_by=self.user)).distinct().order_by('start_time') daily_planner_events1 = [] for requests in requests_per_day: requests_per_day_dict = model_to_dict(requests) daily_planner_events1.append(requests_per_day_dict) daily_planner_events1 = dict() events = add_event_dates(requests_per_day) all_event_dates = [] for event in events: for date in event.dates: if date not in all_event_dates and date.month == self.month and date.year == self.year: all_event_dates.append(date) for event in events: for date in event.dates: if date in all_event_dates and date not in daily_planner_events1 and date.month == self.month and date.year == self.year: daily_planner_events1[date] = [event] else: if date.month == self.month and date.year == self.year: daily_planner_events1[date].append(event) # daily_planner_events[date].append(events) d = '' for requests in requests_per_day: for event in daily_planner_events1: if event.day == day: d += f'<li> {requests.get_html_url} </li>' if day != 0: return f"<td><span class='date'>{day}</span><ul> {d} </ul></td>" return '<td></td>' The code above works...Except it's giving me incorrect output...The problem piece in particular is this... for requests in … -

How to set User's password in django with async, or create User
i have telegram bot(aiogram) for django-site registration, and here is problem. Django have a lot of async methods but i didn't find method for setting user password.

Printing out the event sent to a websocket but receiving received: {"isTrusted":true} as opposed to text received
I have a websocket that listens for a connection and sends data from my frontend to my websocket. I expect my websocket to send back a message indicating that it has received said data and my terminal to print out the text send.

how to add custom templates in django-ckeditor in django
I am trying to use the Templates feature of the CKEditor in Django and I want to add some custom templates in the list. I've used this approach. I've tried editing myvenv\Lib\site-packages\ckeditor\static\ckeditor\ckeditor\plugins\templates\templates\default.js default.js CKEDITOR.addTemplates("default",{imagesPath:CKEDITOR.getUrl(CKEDITOR.plugins.getPath("templates")+"templates/images/"),templates:[{title:"Welcome Template",image:"template2.gif",description:"A template that you can send to clients as a welcome message.",html:' <h2>Welcome</h2> <p>Hi, <strong> Name here </strong> </p><p>You have recently shown an interest . . . </p>'},]}); but it didn't help, I've tried the collect static command but it didn't help either. I am still seeing the same default three templates. I'm not sure but there is another option of using extra plugins in the settings.py file but I don't know how to use it for this problem. settings.py CKEDITOR_UPLOAD_PATH = "file_upload/" CKEDITOR_CONFIGS = { 'default': { 'toolbar':'full', }, } apps INSTALLED_APPS = [ ..., 'ckeditor', 'ckeditor_uploader', ] urls.py urlpatterns = [ path('ckeditor/',include('ckeditor_uploader.urls')),] models.py class text(models.Model): body = RichTextField(blank=True, default="None") So my question is how to add custom templates in django-ckeditor==6.3.2? -
Using django modeling, how do you properly extend a model?
I'm an amateur developer who has been learning python in order to build my first full-stack project, which is an animal exchange site for a game I play. The animals can have up to 3 traits, but some of them have special ones. In the case of animals with special traits, I attempted to extend the base model and add additional traits using a notation someone suggested, but it doesn't seem to work. I know that technically I can just copypaste the base trait set and manually add them in, with a different model every time but that seems like it would bloat my code, and I'd like to be efficient about it. If you notice something else that could be improved, please let me know, thanks. from django.db import models #traits listed in class animal are base traits class ANIMAL(models.Model): MALE = 'MA' FEMALE = 'FE' SHINY = 'SHI' NORMAL = 'NOR' EGG = 'EGG' CHILD = 'CHI' ADOLESCENT = 'ADO' ADULT = 'ADU' ELDER = 'ELD' BIGBONED = 'BIGB' BUTTERFACE = 'BUTT' CHARMED = 'CHAR' CHATTY = 'CHAT' CONSTIPATED = 'CONS' CURVY = 'CURV' EVIL = 'EVIL' EXALTED = 'EXAL' FORTUNATE = 'FORT' FREAKOFNATURE = 'FREA' FROSTBREATH = … -
my css, js and imgs files are not comming in static folder
After running the following command for the Django project: python manage.py collectstatic Some other CSS files are generated, but the following CSS files "that exist in my template folder" are not coming into a static generated folder. When I manually copy-paste these files after the command then it works on local to load, but on production upon deployment to Heroku, it again runs collecstatic command which overwrites those files and then it doesn't load. I also have disabled collect static upon deploying the project to Heroku to prevent overwriting then again it does not load CSS files from the static folder. Please, does anyone, know how I could deal with it? thanks in advance -
Django tests fail due to null ids in content_type table depending on app naming
I added a new app to an established Django project with a PostgreSQL DB. The app name begins with an "a". The app models have foreign keys to models in other apps. The migrations run with no issue and the application starts and runs fine. However, running the tests gives an error like the below as soon as the test database creation starts. Each run creates an error for a different model. From this we can see that content_type table is being populated with null values for the ids. django.db.utils.IntegrityError: null value in column "name" of relation "django_content_type" violates not-null constraint DETAIL: Failing row contains (1, null, threadedcomments, threadedcomment). I have dependencies defined in the migrations file to ensure DB tables are created in the correct order. I have also moved the new app to the end of the list in the INSTALLED_APPS setting. Everything runs as it is supposed to if I do either of the following. Rename the app to start with a different letter. Removing the foreign keys. It looks like the tables are being created alphabetically, despite the migration dependencies. Is there a way to force the order of the table creation? Or is there something … -

Save large CSV data into Django database fast way
I am trying to upload extensive CSV data like 100k+ into the Django database table, I have created the model below and then made a save function to insert the data into the table. It takes a long time so I have written celery code to run this in the background so it doesn't timeout, But the saving data into the table is slower. Is there any way to make the saving faster? class Film(models.Model): title = models.CharField(max_length=200) year = models.PositiveIntegerField() genre = models.ForeignKey(Genre, on_delete=models.CASCADE) def save_csv_to_db(): with open('films/films.csv') as file: reader = csv.reader(file) next(reader) for row in reader: print(row) genre, _ = Genre.objects.get_or_create(name=row[-1]) film = Film(title=row[0], year=row[2], genre=genre) film.save() -

Django pagination: EmptyPage: That page contains no results
When using Django CBV ListView with pagination, if I provide a page that is out of range, I get an error: I would like to have a different behaviour: to fallback to the last existing page if the provided page is out of range. I dug into Django source code paginator.py file and was surprised to find some code that does exactly this: def get_page(self, number): """ Return a valid page, even if the page argument isn't a number or isn't in range. """ try: number = self.validate_number(number) except PageNotAnInteger: number = 1 except EmptyPage: number = self.num_pages return self.page(number) However, it seems this code is never called by default using Pagination. What is the right way to deal with this? Should I make my own paginator by subclassing the Paginator class? Thanks. -
