Django and multi tenancy, data sharing
I'm working on a small project (CRM) using Django and I'm using Django-tenant-schemas, so each user have his own Schema, I would like to know how can I share some data between users ( ex: share user contact list between two users) I was thinking to create a table in the public schema but I don't think is the right solution since I'm isolating data -
How to use the data about objects modifications in Django?
Django stores a history of the modification for every object, it is something we can access to through the Django admin: It contains data about when the object was created/modified, the user who performed the action and the timestamp of the action: By giving a look at the database, I can guess this data is stored in a default table called django_admin_log: I am wondering if we can make use of this data in any way through the instance of a model ? I got used to adding manually my timestamps on every models through an Abstract Base Class, but I am wondering if it is useful in any way ? Or this table records only the modification taking place in the Django admin panel, which would makes the custom timestamp still needed for when the models instance were to be updated outside it. -

What is a good way to store guest user information that may be saved to a permanent user after registration in django?
I have a RESTful django webapp that allows users to take quizzes in a progressive system where the quizzes become increasingly difficult. Their progress is saved when they answer a question. I'm using django-rest-framework. class User(AbstractUser): pass class IntervalsProfile(models.Model): # Belongs to User model in 1-to-1 relationship # If User is deleted, then the corresponding IntervalsProfile will be deleted as well user = models.OneToOneField(settings.AUTH_USER_MODEL, related_name='profile', on_delete=models.CASCADE) level = models.IntegerField(default=0) current_level = models.IntegerField(default=0) # Level the user is currently viewing/on I would like users to be able to play as a guest, and if they so choose, register in order to save their progress. I cannot figure out how to save this guest information or how to save it once they register. I've searched thoroughly and all the solutions I see are either several years old or seem too cumbersome (such as adding a check for authentication in every view and having 2 cases for each view). Any advice or guidance would be much appreciated. -
Open and validate files to Django (Wagtail) admin before upload
thanks in advance, I'm currently trying to create some data types which are pretty much just Wagtail's default document type (implemented on the admin similar to Django's FileField) with a custom clean (validation) method. However, the problem I'm getting is when I'm uploading the file, I get an IOError when my program tries to open the file to process. Validating the extension is easy enough, but the problem lies when I actually have to open the file. I'm guessing when I try to open it the document isn't uploaded on the server yet when it tries to validate all the information, so opening it would be impossible. I wasn't able to find any information identifying whether this is even possible, and this seemed like a core Django constraint, not just Wagtail. P.S. I'm intentionally not showing code because it doesn't really clear to much up, but if you'd like to see it I'd be happy to provide it or anything else. -

django - DecimalField max_digits, decimal_places explained
So I'm just starting out with Django and using it to store forex prices which are represented as 1.21242, 1.20641, etc... model.py from django.db import models # Create your models here. class ForexPrice(models.Model): openPrice = models.DecimalField(max_digits=6, decimal_places=6) highPrice = models.DecimalField(max_digits=6, decimal_places=6) lowPrice = models.DecimalField(max_digits=6, decimal_places=6) closePrice = models.DecimalField(max_digits=6, decimal_places=6) My Question Is: How do the max_decimal and decimal_places attributes work? I'm using 6 for both fields assuming max_digits=6 will allow values to be stored up to 6 digits ie: 123456.000000 while decimal_palces=6 will support values up to 000000.123456. Is this assumption correct or am I missing something? Getting the following error when I save the record to the DB: A field with precision 6, scale 6 must round to an absolute value less than 1. -
Django-cms admin url 404 after language change
I recently started learning Django & Django CMS, and was trying to change the language of my website from English to Dutch, I migrated over my pages using Page.objects.filter(languages='en-us').update(languages='en') Title.objects.filter(language='en-us').update(language='en') CMSPlugin.objects.filter(language='en-us').update(language='en') In my settings.py I also changed LANGUAGE_CODE to 'nl' and set my languages and CMS languages as follows LANGUAGES = ( ## Customize this ('nl', 'Nederlands'), ) CMS_LANGUAGES = { ## Customize this 1: [ { 'code': 'nl', 'name': 'Nederlands', 'redirect_on_fallback': True, 'public': True, 'hide_untranslated': False, }, ], 'default': { 'redirect_on_fallback': True, 'public': True, 'hide_untranslated': False, }, } This works like a charm for the normal pages, but as soon as I try to open the admin interface I get the following error Request Method: GET Request URL: http://localhost:8000/nl/en/admin/cms/page/?language=en Raised by: cms.views.details Using the URLconf defined in PinManagementSite.urls, Django tried these URL patterns, in this order: sitemap.xml nl/ admin/ nl/ ^cms_login/$ [name='cms_login'] nl/ ^cms_wizard/ nl/ ^(?P<slug>[0-9A-Za-z-_.//]+)/$ [name='pages-details-by-slug'] nl/ ^$ [name='pages-root'] ^media/(?P<path>.*)$ ^static/(?P<path>.*)$ The current path, /nl/en/admin/cms/page/, didn't match any of these. As far as I can see I configured it all correctly, but when I go to the admin pages it tries to route me through /nl/en instead of just /nl/ and I can't figure out why. For completeness … -
Access a field's custom class in Django's ModelForm
I'm working on a ModelForm in Django that uses a Model, which has a custom CharField. When handling form errors I want to show the user valid examples (I thought this shouldn't be part of the raised ValidationError). However, when I try to access the fields using myform.fields by getting the invalid fields and the corresponding error messages using myform.errors.items() type(myform.fields["myfield"]) returns <class 'django.forms.fields.CharField'> instead of my custom MyField. Therefore myform.fields["myfield"].test() raises AttributeError: 'CharField' object has no attribute 'test'. How do I get the correct MyField instance from form.fields? class MyField(models.CharField): pass class MyModel(models.Model): myfield = MyField(max_length=20) class MyForm(forms.ModelForm): class Meta: exclude = tuple() model = MyModel myform = MyForm() print(type(myform.fields["myfield"])) -

Request can only be served after Gunicorn Worker Timeout and new Worker is booted
I have a Django application in Docker using Gunicorn to run the web server. If I request any URL, say app.com/dashboard, the page loads for 30 seconds. The reason it loads for 30 seconds is because that's how long the Gunicorn web worker to timeout, exit, and boot a new worker with a new pid. This is what shows up in the logs after a request and waiting for the worker to timeout. web_1 | [2021-04-28 17:51:57 +0000] [1] [CRITICAL] WORKER TIMEOUT (pid:7) web_1 | [2021-04-28 12:51:57 -0500] [7] [INFO] Worker exiting (pid: 7) web_1 | [2021-04-28 17:51:57 +0000] [9] [INFO] Booting worker with pid: 9 Once the new worker is booted, the page is served instantly. Has anyone experienced something similar to this before? -
Result type from cursor.fetchall() is list of tuples, but doc shows tuple of tuples
from django.db import connection conn = connection.cursor() conn.execute("some select query..") print( conn.fetchall() ) This shows that result from cursor.fetchall() is list of tuples, though in docs there is example: >>> cursor.execute("SELECT id, parent_id FROM test LIMIT 2"); >>> cursor.fetchall() ((54360982, None), (54360880, None)) That shows that result is not list, but tuple of tuples.

DJango use templates from seperrate AWS S3 Bucket
I have a Django server running in an elastic beanstalk environment. I would like to have it render HTML templates pulled from a separate AWS S3 Bucket. I am using the Django-storages library, which lets me use static and media files from the bucket, but I can't figure out how to get it to render templates. The reasoning for doing it like this is that once my site is running, I would like to be able to add these HTML templates without having to redeploy the entire site. Thank you -
Apache httpd and Easy Apache 4 (Installing mod_wsgi for python app)
It's been a while but I am running into an issue and could not find any answers elsewhere. I pay for a dedicated server that is running Easy Apache 4 with Centos 7. I have root access to everything so no limitations. I am in the process of deploying a Python/Django app on the server for a client. When trying to install mod_wsgi it errors out stating it needs the package httpd-mmn. I can install the httpd module using yum but I am worried about conflicts since the server is using Easy Apache 4. Is this a relevant concern? I have a bunch of php sites on my server and I am afraid I'll break it. For the record, I do not want to use the experimental easy apache mod wsgi as it's, well...experimental and a use at your own risk situation. Any thoughts or recommendations would be great. -
