{'sales@mydomain.co': (553, b'5.7.1 <abc@gmail.com>: Sender address rejected: not owned by user sales@mydomain.co')}
I have a contact form on my website where users fill in their name, email and message to contact support which in this case is sales@mydomain.co and say the sender's email is abc@gmail.com. When a user submits the form, the form yields an error {'sales@mydomain.co': (553, b'5.7.1 <abc@gmail.com>: Sender address rejected: not owned by user sales@mydomain.co')} The form works if the sender's email belongs to the organization sales@mydomain.co. Is it possible to for a user to send an email(using a different organization email, such as Gmail) through the online form? here is my forms.py class ContactForm(forms.Form): name = forms.CharField(label='Your name', max_length=100) email = forms.EmailField(label='Your email', max_length=100) message = forms.CharField(max_length=600, widget=forms.Textarea) def send_mail(self): logger.info("Sending email to customer service") subject = "Site message" message = f"From: {self.cleaned_data['name']} <{self.cleaned_data['email']}>\n{self.cleaned_data['message']}" sender_email = self.cleaned_data['email'] # Use the user's email as the sender recipient_list = ['sales@mydomain.co'] # My domain email address send_mail( subject, message, sender_email, recipient_list, fail_silently=False, ) -
Attempting to migrate an Django ImageField, but failing to migrate
I am currently facing a problem with trying to migrate a Django Image field from a folder named media_root located inside a folder named static_cdn inside of my current project here is what my current file structure looks like as that may help; veganetworkmain -----profiles -------static_cdn ---------media_root ----------test.png Test.png is a png file that is generated using a picture generation algorithm using Pillow, here is what Test.png actually looks like: However what actually happens when I try to implement the code to get the picture into my program using a Django Image Field is that it just becomes white as seen here: I had tried methods like using python manage.py makemigrations, python manage.py migrate, changing the static by changing url_patterns and setting and even python ./manage.py makemigrations profiles.

400 Bad Request Error in an application using Django, Gunicorn, and Nginx
I've been trying to troubleshoot my issue with no success for a while now, so I hope posting here helps. I am developing an application using Django REST Framework, Gunicorn, and Nginx. The idea is to have Gunicorn serve the Django applicaiton, and have Nginx be used as a reverse proxy that holds the SSL certs. I've referenced multiple guides on hosting applications using these three technologies, with little success. I have my Django application connected to gunicorn using a sock file on port 80, and my Nginx server blocks listen for both port 80 and 433 (for SSL purposes). I have tried just about everything I can think of, and yet I am still getting a 400 - Bad Request error whenever I navigate to the domain that should serve the API. This is my Nginx sites-available file, with just a couple of names changed for security purposes: server { listen 80; server_name www.querymarketplace.net; return 301 http://querymarketplaceapi.net$request_uri; } server { listen 80; server_name querymarketplaceapi.net 157.245.10.103; location /static/ { root /home/jbisc/qm_marketplace/; } location / { include proxy_params; proxy_pass http://unix:/home/jbisc/qm_marketplace.sock; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-Host $server_name; } } server { listen 443 ssl; listen [::]:443 ssl; # Optional: … -
How do I pass a Javascript variable to my Django framework to be used in template or via get_context?
I have been working to pass form values to a modal using Django. I have gotten most of the way there, but I can't quite make out how to connect the two....

A function working in a custom file but not in a "custom migration" on Django
I am beginner in Django and just started learning migrations. In a DB table, I am trying to remove a row that has a specific field value. When I create a custom file which uses Django settings, the function properly deletes the row. But when I use the snippet in another function in a custom migration file, the deletion doesn't take place. It is possible that I am missing something elementary as a beginner. So I am trying to delete all orders the status of which is cancelled. The function that works in a separate file is: os.environ.setdefault("DJANGO_SETTINGS_MODULE", "orm_skeleton.settings") django.setup() from main_app.models import Order def delete_test_fnc(): all_orders = Order.objects.all() for i in range(len(all_orders) - 1, -1, -1): order = all_orders[i] if order.status == "Cancelled": order.delete() delete_test_fnc() The custom migration where delete doesnt work (other two modifications work without issues) is: from datetime import timedelta from django.db import migrations CURRENT_ORDERS = [] def modify_delivery_warranty(apps, schema_editor): global CURRENT_ORDERS orders = apps.get_model("main_app", "Order") all_orders = orders.objects.all() CURRENT_ORDERS = all_orders for i in range(len(all_orders) - 1, -1, -1): order = all_orders[i] if order.status == "Cancelled": order.delete() elif order.status == "Pending": order.delivery = order.order_date + timedelta(days=3) elif order.status == "Completed": order.warranty = "24 months" order.save() … -

How to hide password field from request.user in django?

Running DRF endpoints in a venv with gunicorn

I run gunicorn like this: /path_to_venv/bin/gunicorn But in the API code I log os.getenv('VIRTUAL_ENV') and it's None. Is that valid evidence that the code is not running in the venv? If so, how can I force it to run in the venv? If not, how can I validate that it is running in the venv? -

Django broken pipe error when handling large file
A server developed using the Django framework is hosted in a local environment, and a broken pipe error occurs in the process of processing large files. The current problem is the code below, which is to respond by changing the DICOM file to the png extension through a separate view to deal with the DICOM file. There is no problem in normal cases, but a broken pipe error occurs when processing about 15MB of files. # javascript code for request file data in html template function loadImages(images, fileType, index) { event.preventDefault(); if (index < images.length) { var image = images[index]; var fileName = image.image_url.split('/').pop(); var imageData = { fileName: fileName, }; imageInfoArray.push(imageData); var img = new Image(); img.onload = function() { var filePreviewHTML = ` <li class="add-image-${index}"> <a href="javascript:void(0)" class="img-wrap" data-id="${index}"> <img src="${(fileName.endsWith('.DCM')) ?

Flutter Web: Assets Not Loading Correctly from main.dart.js Using Current Relative URL Instead of Base HREF
I'm currently working on hosting a Flutter web application using a Django web server on an Ubuntu 20.2 environment. The Flutter version I'm using is 3.13.5, channel stable, and my project structure has the Flutter web project located in the static folder. I've been facing an issue where the Flutter web application cannot locate the FontManifest.json file. It seems like this file is being sought using the current URL (relative) instead of the base URL defined in the index.html file. Assets loaded from index.html work correctly with the base href directed to static directory, but those loaded from main.dart.js and are using the current URL. Has anyone encountered a similar issue or has insights on how to ensure that all assets, including FontManifest.json, loaded from main.dart.js use the base URL as intended? I am almost inclined to reference the missing visual assets in main.dart through the Network module but I think Flutter should have a configuration option to determine the static-uri-location where the app will be hosted with all it's static files instead of just having to rely on the relative-uri for static files. 1.I tried fetching those 2 files (AssetManifest.bin + FontManifest.json) through the main.dart.js but that does not … -

Django Objects Filter received a naive datetime while time zone support is active when using min max range
So this question is specifically about querying a timezone aware date range with max min in Django 4.2. Timezone is set as TIME_ZONE = 'UTC' in settings.py and the model in question has two fields: open_to_readers = models.DateTimeField(auto_now=False, verbose_name="Campaign Opens") close_to_readers = models.DateTimeField(auto_now=False, verbose_name="Campaign Closes") The query looks like allcampaigns = Campaigns.objects.filter(open_to_readers__lte=today_min, close_to_readers__gt=today_max) Failed Solution 1 today_min = datetime.combine(timezone.now().date(), datetime.today().time().min) today_max = datetime.combine(timezone.now().date(), datetime.today().time().max) print("Today Min", today_min, " & Today Max", today_max) returns the following which would be a suitable date range except it also gives the error below for both min and max.

This can be caused by a too short worker timeout or by a memory leak. what is it? how can i solve this? The project should have fetched the data from datasets and then compare the user input and show the result. -
