How to initialize Django database without using existing migrations?
I have a Django project, which contains dozens of migrations, and I want to initialize it on a new database. How do I do this without running all the migrations, which can take a lot of time to run? In earlier versions of Django, it used to have a "syncdb" command that you could run to create all tables in a blank database, bypassing all migrations. Current Django's migrate command has a --run-syncdb option, but the docs say: Creates tables for apps without migrations. Since all my apps have migrations, I interpret this to mean it does nothing in my case. Does modern Django no longer have anyway to initialize a database without tediously running through every single migration? Note, I'm not asking how to initialize a Django database. I'm asking how to do it more efficiently than by running migrations, which are designed to modify an existing database, not initialize one from scratch. -
Save generated image to model AND upload to S3?
I cannot find documentation on how to do what I need to do. My goal(s): User fills out a form with basic info Server-side a qr code is generated for that user. This qr code image needs to be uploaded to S3 to not bog down the server storage. This needs to be referenced in a model. WHY? This image will need to be displayed later in various front-end frameworks so at least the URL should be somewhere. It is stated lower but note: the s3 upload IS functional via form in admin. Currently I am building this out as an API to be used by various front-end frameworks so no forms in django will be used. All code is in testing mode so there is currently no security (just FYI). I am just trying to get this functionality working. Current model: from django.db import models # Customer model only class Customers(models.Model): customerId = models.CharField(max_length=25, unique=True) qr = models.FileField(upload_to='media/') #THIS IS WHERE IT WOULD BE STORED email = models.EmailField(unique=True) password = models.CharField(max_length=255) phone = models.CharField(max_length=20, unique=True) displayTag = models.CharField(max_length=255, unique=True) Views.py that is doing the saving from django.shortcuts import render from django.http import JsonResponse as j from qrewards_api_pj.helper import generate_id, … -
Django collectstatic ends up with "AWS S3 Boto3 Python - An error occurred (AccessDenied) when calling the DeleteObject operation: Access Denied"
I'm using Heroku+S3+Cloudfrong and I'm facing the titled error when trying to collectstatic. I'm having all the necessary IAM permissions, including AmazonS3FullAccess. The django settings set AWS_DEFAULT_ACL=None. My S3 bucket is configured with "Object Ownership" with "ACLs enabled" and it unblocks all public access (i.e. all set as public).

Ngnix + Django + Gunicorn not found static and media
I'm trying to deploy the site on the server, but static and media are not loaded on it. I tried to juggle the url pattern and config nginx, but all in vain. The most interesting thing is that he loads only index.css, and does not see all the others server { listen 443; server_name domain.com; location /media { alias /root/djangoproj/media; } location /static { alias /root/djangoproj/static; } location / { proxy_pass http://unix:/run/gunicorn.sock; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_no_cache 1; proxy_cache_bypass 1; } } I tried to juggle the url pattern and config nginx -

Why am I seeing an NGINX 502 error in Chrome, only on MacOS?
I have a very strange issue happening. Multiple users have reported it, across multiple computers, and multiple sites. They keep getting an NGINX 502 error. It only occurs on Google Chrome. It has only been reported from users using MacOS. I have not been able to recreate the issue I haven't found anything in logs, aside from I can see the access failure. The only commonality between the sites, is they have all been a Django/NGINX/Uwsgi stack on CentOS. The issue is not present if the user switches to incognito. The issue persists if the website cache is cleared. The issue disappears if the entire browser cache is cleared. One site is new, the other is old and has not had a configuration change since the problem began. The problem is sporadic, and seemingly random. First noted in the past ~1 month. Any thoughts on this would be helpful. Since I can't recreate the issue, I am having a hard time troubleshooting. Thanks in advance. -
Django Select2 field query return no select options
On a Django model, I have a foreign key field 'owner', refer to User model. I have a view class and form class for the model instance creation page. I made the form 'owner' field using select2 widget as below. All worked fine. class OwnerWidget(ModelSelect2Widget): search_fields = ["name__istartswith", "email__icontains",] Now I changed the page to use bootstrap modal. All other model fields behaved okay but not the 'owner' field: when I type in search characters like 'te', it start to send query to the server, but server returned 404 not found. See log below. "GET /select2/fields/auto.json?term=te&_type=query&q=te HTTP/1.1" 404 2699 I have nowhere configured the path '/select2/fields/auto.json'. I guess it's select2 default path. Did I miss anything on the view or form classes in order for this path to work? or I need to configure a different URL path somehow base on my view and form? I added line below to the widget, but no help. model = settings.AUTH_USER_MODEL I have no clue how this select2 search work. Any help appreciated. -

There is a problem for updating database using forms.form in Django and I want use only one 'update' button to update many database data
what I want do make is that show the existing data in the database to a user through HTML page. let a user update the existing data if he wants to do. Promblem 1> the problem is that,when running my code, a user input the new data and clicked 'update' button, but the update did not work. I don't know whether it is the reason or not, anyway, when I put 'def show_data' and 'def input' together, updating did work well. However 'def show_data'and 'def input' should be separate. 'def show_data' : it is for saving the data from excel file into the database using pandas 'def input': it is for receiving the input data from a user and updating the existing data with the input data Promblem 2> There are many 'update' button in the web page. I want to make only one 'update' button at the bottom of web page for updating all data user input into the database.

Wagtail custom permissions
I have a wagtail site. I have certain pages that I only want certain users to be able to access. I have used the standard django permissions setup to do this: models.py class Case(TimeStampedModel): case_userdefined_id = models.CharField( max_length=17, null=False, blank=False, unique=True, default='default' ) user = models.ForeignKey( get_user_model(), blank=False, null=True, on_delete=models.SET_NULL) class Meta: permissions = (("can_access_case", "Can Access case"),) views.py class CreateCaseView(PermissionRequiredMixin, CreateView): permission_required = 'Case.can_access_case' print('test2') template_name = 'cases/create_case.html' form_class = CaseForm success_url = reverse_lazy('patients') def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) form = CaseForm() context['form'] = form return context wagtail_hooks.py from django.contrib.auth.models import Permission from wagtail import hooks @hooks.register('register_permissions') def view_restricted_page(): return Permission.objects.filter(codename="can_access_case") Then in the wagtail admin I have created a group 'case_access' and ticked the custom permissions to allow access. I have then made various users members of this group. However these users still get a '403 forbidden' screen, it is only superusers that can access the relevant pages. What else do I need to do? -

How to better structure variations for Ecommerce site
I am working on an e-commerce application in Django. It allows for product variations. My first impulse has been to go with multi-table inheritance, where variants have their own table different from the main product table. Both of these inherit an abstract table, so they share common properties. Then in the frontend, implicitly place the main product as the first variation in the variation list. The thing I am struggling with deciding whether to duplicate main product as variant like in the Amazon custom implementations of variations, as shown in this image: The primary main product always seems to be the first expected product. But clicking on that, you see that the circled label(color) in the above image, also changes, in this case 01-black. My question is, is Amazon duplicating the main product as a variation too? Which means, it will have it's specific features like the color name. That would mean duplication. If in case then that Amazon is implicitly displaying the main product as the first variation, how come it has unique property values like the color name ````01-black``? -

Google Cloud Run Gunicorn Multi-Threaded Django Request Blocked on Cold Start
I have a Django application deployed on Google Cloud Run using a Gunicorn server. There is a daily task triggered by Google Cloud Scheduler. The task job involves patching a Microsoft subscription. For this patch to complete successfully, Microsoft makes a call to another API endpoint on the same Django application to validate a token. The Gunicorn server is running with multiple threads. When the task is triggered and the container has a cold start, the validation request is blocked, the patch request fails and the container only responds to it after the patch failure. However, if the container is warm, the task completes successfully and the additional thread is able to respond to the validation check. Any idea why this is occurring and how it can be addressed? This was working previously but started encountering this error in recent weeks. Have tried setting multiple workers and more threads on the Gunicorn server as well as enabling CPU boost on Cloud Run but neither of these worked.
