Wagtail and Django
I'm experienced with Django and I've just started looking into wagtail integration in order to provide a better UX to the content management. Let's say I have an existing Django app and I would like to keep the same structure but this time the contents can be managed from the wagtail admin panel instead of the Django one. Is there a way to let's say created a parallel Model which mirrors the existing Django Model. So I add contents from wagtail admin and it will add those content to the same DB schema . I know you can created a 1 to 1 relation to the existing django model, that might be one way of approaching it I think. Not sure what the best way to do so ?? Also it seems like you will have to provide an html template for each Model correct ? When does it make sense to use it ? Do you actually save time instead of crating you own UI ? What are the alternatives there ? Thank you in advance -
Djoser reset password flow to javascript frontend (Vue)
I've got most of this reset password flow done using djoser in django. I get the email successfully.

Migrating wagtail snippet model into page model
I'm wanting to convert an existing snippet model into a page model, along with migrating all existing data from the snippet model. Is there a way to do this without having to manually convert the data/ create a script to generate pages from the existing models? I've updated the model, ran the migrations etc. and can create new pages for this type in the wagtail UI, but the existing data hasn't been migrated over and there's no new page models for it. References/links to the old snippet models are still intact, but there's nowhere to view/edit the model as it no longer appears as a snippet and hasn't been migrated over to a page. -
Django Flowbite dropdown doesn't work when I'm looping it in template for loop
Fowbite dropdown works when I write it out of for loop, but when I'm moving it into the for loop it stops working. And reason is not html id.

Prevent Prettier from breaking Python code
I am writing some conditions in my django html file and upon every save, vs code Prettier rearranges my code but it's doing it the wrong way hence creating errors.

How to style the CSS bootstrap 'col' elements?

Django migrate error on first migration due to forms Meta class using User
I am getting the auth_user does not exist error on manage.py migrate when I try to migrate my app for the first time. This is due to the following part in one of my forms: class MyForm(ModelForm): def __init__(self, *args, **kwargs): ***dothings and super init*** def clean(self): ***dothings**** # This is where it goes wrong: class Meta: owner_choices_base = User.objects.values_list('username', flat=True) owner_choices = [(c, c,) for c in owner_choices_base] owner_choices.insert(0, (None, None,)) model = SomeModel widgets = { 'owner': forms.Select(choices=owner_choices), 'concerned_business_lines': forms.SelectMultiple() } It seems this executes before any of the migrations are done and it will see that User related things actually don't exist yet. It works nicely when I delete the Meta part and after that recreate it. Now I would like to have an app that works without having to comment out code for the first time you create it, but I have no idea how to get around this issue while still being able to populate my "special" owner field with users and I hope someone here will have an idea. For more information on why the Meta class is there: The owner field in the form is just a charfield, but I want to make … -

improve django queryset performance
I have a set of products that I need to fetch from my API, along with their respective discounts. Initially, I used the subqueries approach to achieve this, but it has led to significant performance issues as the dataset has grown. I'm looking for suggestions on how to refactor the queryset to improve the performance. Any ideas or alternative methods to efficiently retrieve product discounts would be greatly appreciated. This is the QuerySet: active_vouchers = Voucher.dal.get_active_vouchers( voucher_kind=VoucherKindChoices.Static_based ).prefetch_related('voucher_ranges__packs__expense') is_discounted_subquery = active_vouchers.filter( voucher_ranges__packs__product__id=OuterRef('pk'), min_basket_value=0 ) voucher_type = is_discounted_subquery.filter(voucher_ranges__packs__product__id=OuterRef('pk')).\ values('voucher_type')[:1] voucher_kind = is_discounted_subquery.filter(voucher_ranges__packs__product__id=OuterRef('pk')).\ values('voucher_kind')[:1] voucher_fixed_amount = Voucher.bll.convert_voucher_fixed_price_currency(active_vouchers, currency.code).\ filter(voucher_ranges__packs__product__id=OuterRef('pk'), ).values('converted_fixed_price')[:1] voucher_percent_amount = is_discounted_subquery.filter( voucher_ranges__packs__product__id=OuterRef('pk'), ).values('value_percentage_based')[:1] qs = self.annotate( is_discounted=Case( When( Q(Exists(is_discounted_subquery)), then=True, ), default=False ), voucher_kind=Case( When( Q(is_discounted=True), then=Subquery(voucher_kind) ), default=Value('no_voucher') ), voucher_type=Case( When( Q(is_discounted=True), then=Subquery(voucher_type) ), default=Value('no_voucher') ), fixed_static_discount=Case( When(Q( is_discounted=True, voucher_kind=VoucherKindChoices.Static_based, voucher_type=VoucherTypeChoices.Fixed_price_based ), then=Subquery(voucher_fixed_amount) ), default=0, output_field=MoneyCurrencyOutput(currency) ), percentage_static_discount=Case( When(Q( is_discounted=True, voucher_kind=VoucherKindChoices.Static_based, voucher_type=VoucherTypeChoices.Percentage_based ), then=Subquery(voucher_percent_amount) ), default=0, ), price_after_static_discount=Case( When( Q( is_discounted=True, voucher_kind=VoucherKindChoices.Static_based, voucher_type=VoucherTypeChoices.Fixed_price_based), then=ExpressionWrapper( F('default_pack_price') - F('fixed_static_discount'), output_field=MoneyCurrencyOutput(currency), ) ), When( Q( is_discounted=True, voucher_kind=VoucherKindChoices.Static_based, voucher_type=VoucherTypeChoices.Percentage_based), then=ExpressionWrapper( F('default_pack_price') * (100 - F('percentage_static_discount')) / 100, output_field=MoneyCurrencyOutput(currency), ) ), default=0, output_field=MoneyCurrencyOutput(currency) ), ) return qs This the QuerySet explain and the query in SQL: https://explain.depesz.com/s/xIgD#source Im not sure why planning time is … -

Command line not recognizing 'djstripe_sync_plans_from_stripe' or 'djstripe_sync_plans'
Has anyone else encountered / solved this issue? We've found no insight into this from the web. But as far as we can tell, I have to run at least one of these commands to sync our Stripe account with our Django database models. The CLI command that's worked for all our other teammates has been: python3 manage.py djstripe_sync_plans_from_stripe The expectation, as I understand, is that this command should sync Django models from relevant data on the Stripe account, however my terminal doesn't recognize this command. This is the first time the team has experienced this while onboarding a new collaborator. One command that is recognized is: python3 manage.py djstripe_sync_models This command produces a number of funky errors which may or may not be related to the issue at hand, but it does run. This illustrates that some of these "djstripe" commands are recognized, just not the one that we need. Bottom line, we need to find a fix or a workaround. -

All of those are installed on my virtual environment (env) requirements.txt asgiref==3.7.2 botocore==1.31.5 cachetools==5.3.1 certifi==2023.5.7 cffi==1.15.1 charset-normalizer==3.1.0 colorama==0.4.6 cors==1.0.1 dj-database-url==2.0.0 Django==4.2.2 django-cors-headers==4.1.0 django-heroku==0.3.1 django-storages==1.13.2 djangorestframework==3.14.0 djangorestframework-simplejwt==5.2.2 filelock==3.12.2 future==0.18.3 gcloud==0.18.3 gevent==22.10.2 googleapis-common-protos==1.59.1 greenlet==2.0.2 gunicorn==21.2.0 httplib2==0.22.0 idna==3.4 jmespath==1.0.1 jws==0.1.3 oauth2client==4.1.3 oauthlib==3.2.2 packaging==23.1 Pillow==9.5.0 protobuf==4.23.4 psycopg2==2.9.6 psycopg2-binary==2.9.6 pyasn1==0.5.0 pyasn1-modules==0.3.0 pycparser==2.21 pycryptodome==3.18.0 PyJWT==2.7.0 pyparsing==3.1.0 Pyrebase4==4.7.1 PySocks==1.7.1 python-dateutil==2.8.2 python-dotenv==1.0.0 python-jwt==2.0.1 pytz==2023.3 requests==2.29.0 requests-file==1.5.1 requests-oauthlib==1.3.1 requests-toolbelt==0.10.1 rsa==4.9 s3transfer==0.6.1 six==1.16.0 sqlparse==0.4.4 tldextract==3.4.4 typing_extensions==4.7.1 tzdata==2023.3 uritemplate==4.1.1 urllib3==1.26.16 whitenoise==6.5.0 zope.event==5.0 zope.interface==6.0 But when I try to import django-heroku it says "Import "django_heroku" could not be resolved".Issue. File structure: image. What should I try? I want the installed packages to work (dj_database_url doesn't work too). I tried reinstalling the necessary packages (also the whole environment), but it simply doesn't work. I'm sure I'm using my virtual environment (env) -
PostgreSQL/Django: target >2 Billion (2.000.000.000) Limit/Advice
I developed an R&D database to store machine time data. From this raw time I calculate/extract statistics. Suggestions/advice is needed regarding data size limits. Setup: Django (Python) backend with PostgreSQL database. Concept: Every machine: stores about 300.000 records split over two tables: index_table and data_table. An index_table contains machine info (setting, labels, operator). The data_table has 7 fields (index*, step*, datetime, value, setpoint, comment, active) where index* is an foreign key to index table and step* an foreign key to measurement settings. Comment field (text) about 30 chars. Workflow: Normally raw data (300.000 records) is uploaded to data_table and statistics are calculated/extracted. Typical user: Zero: Upload and extract datafile to database (index_table, data_table). Every time about 300.000 records in data_table. After that user "initiates calculate statistics". First: "production" report request is to collect statistics (no problems relative small tables). Second: "R&D" report request raw data (300.000 records) and server make some transformations and plots (Plotly) over HTML Status: Currently I uploaded 400 machines. The data_table has 30.000.000 (30 million) records and the database size is: 10Gb. The server is running on a low end workstation. Performance is fine and smooth. And above my expectation (last large database experience 20 years … -
How do I create multiple different types of POST requests in Django that can each be handled in a different way?
In my django project, I have a page which allows users to add a task through clicking a button and entering the details of the task(in a modal window). Users are also able to edit/delete tasks by clicking a button next to each respective task. I've run into the issue of not being able to submit different types of post requests that can handle each operation individually. Here is an image of the page for clarity: User interface I'm not sure how to create two different "types" of POST requests that can handle these two cases. One "type" of POST request for adding a task and another for editing/deleting it. Just for reference, this is what the modal window would look like to add a task: add task Right now this is the URL I want both of them to redirect to when the form is submitted(which is just the original page after the modal window is removed after submission) is: path('team/<str:team>/', views.team_view) This is the team_view function currently: def team_view(request, team): connection.connect() team_url = team[4:] if(team[4] == '1'): team_num = team[4:] else: team_num = team[5] tasks = Task.objects.filter(team_id=team_num) context = { 'task_list' : tasks, 'team_id' : team_num, 'team_id_url': team_url …
