Filtering Forms in Django
I am making a small project to rate salesmen. I have regions and each region has its salesmen. So, if region "blahblah" is selected, form should show salesmen choices which are related to that region.

Heroku error H10 and fwd, my site won't function and I'm unable to determine what actions to take to correct the problem
I just uploaded sync'd my working GitHub repository to Heroku, and when I load the page, I get the "appplication error" page. This is a Django/Python project for school.

How to add "-" in django rest_framework Serializer class variables?
I am writing a rest_framework Serializer class for basic validations class ValidateSerializer(serializers.Serializer): client_name = serializers.CharField(allow_blank=False, trim_whitespace=True) and my request data contains "-" in the keys, so I need something like this class ValidateSerializer(serializers.Serializer): # Like the below class variable? I know it is not possible with python variable declaration. client-name = serializers.CharField(allow_blank=False, trim_whitespace=True) I've checked the rest_framework CharField to find out any kwargs that allow me to accept data like client_name = serializers.CharField(name='client-name') So, is it possible to accept - in the Serializer class variables from request data? -
Images in react not displaying
I'm using django and react to build an application. There are some images in react public folder which are being used in different pages. The rest images are coming from django. Both images (images from react and django) were displaying on the browser until I combined react and django and started serving react index.html page from django (using react build folder in django).

How do I export my django model into custom csv?
I have a Django app in which I maintain products for a webshop. Since many products have multiple variations and working in Excel is not optimal, I thought Python could help me and make the work easier. However, for the import into my store system I need a CSV file and here comes my problem. I have a model with five fields where two are multiple fields (django-multiselectfield). SIZES = (('16', 'Size 16'), ('17', 'Size 17'), ('18', 'Size 18'), ('19', 'Size 19'), ('20', 'Size 20')) COLORS = (('white', 'White'), ('black', 'Black'), ('blue', 'Blue'), ('red', 'Red'), ('yellow', 'Yellow')) class Items(models.Model): name = models.CharField(_('Name'), max_length=254, null=True, blank=True, default='',) sku = models.CharField(_('SKU'), max_length=254, null=True, blank=True, default='',) size = MultiSelectField(_('Size'), choices=SIZES) color = MultiSelectField(_('Color'), choices=COLORS) price = models.DecimalField(_('Price'), max_digits=7, decimal_places=2) I created two products to demonstrate my needs In my CSV file, for example, I need a new line for each size and color so that the variation is created correctly in the webshop software. So my CSV would have to look like this: "type","sku","attribute 1 name","attribute 1 value","attribute 2 name","attribute 2 value" "variable","abc01921","size","16","color","white,black,blue" "variation","abc01921_white_16","size","16","color","white" "variation","abc01921_black_16","size","16","color","black" "variation","abc01921_blue_16","size","16","color","blue" "variable","abc01831","size","16,17","color","black,blue" "variation","abc01831_black_16","size","16","color","black" "variation","abc01831_blue_16","size","16","color","blue" "variation","abc01831_black_17","size","17","color","black" "variation","abc01831_blue_17","size","17","color","blue" How do I best implement this successfully?

How to allow CORS from chrome extension origin on django after set white list to all?
I'm trying to re-add CSRF token protection to an API made with Django and deployed to heroku. Local tests with the CSRFToken verification allowed worked fine before I uploaded the web app to heroku but now that I'm in the final tests is not working unless I add the csrf_exempt decorator to the the Django view. I obtained the following error with Django 3.1.7: Referer checking failed - no Referer I was using Django 4.0 on heroku and I decided to try with 3.1.7 version because I tought it could resolve my problem since in this question I understood that this was because in previously Django versions CSRF domain was not checked: Forbidden (403) CSRF verification failed.

Using subdomains for redirection only (Special for Django)
Suppose that my domain is example.com I want to set subdomains such as blog.example.com, contact.example.com ... In my use case: The subdomains will never have unique content. They will always redirected to determined URLs. Assume that, --> Site objects were created for them. (using The “sites” framework) site_1 : example.com site_2 : contact.example.com site_3 : blog.example.com ... --> Then, Redirects are handling with The Redirects app. Example Redirects Goals: >>> redirect_1 = Redirect.objects.create( ... site_id=1, ... old_path='/contact-us/', ... new_path='/contact/', ... ) >>> redirect_2 = Redirect.objects.create( ... site_id=2, ... old_path='/', ... new_path='https://example.com/contact/', ... ) >>> redirect_3 = Redirect.objects.create( ... site_id=3, ... old_path='/first-blog/', ... new_path='https://example.com/blog/first-blog/', ... ) My questions - Can The sites framework and The redirects app be used this way with subdomains? - If possible, how should subdomains be configured for this use case? Note: Assume that there is no configuration related to subdomains in the project and that what is wanted to be done is prefer to done by Django side as much as possible. -

I'm attempting to send consumers.py information to display on the client end outside of consumers.py. I've referenced Send message using Django Channels from outside Consumer class this previous question, but the sub process .group_send or .group_add don't seem to exist, so I feel it's possible I'm missing something very easy. Consumers.py from channels.generic.websocket import WebsocketConsumer from asgiref.sync import async_to_sync class WSConsumer(WebsocketConsumer): def connect(self): async_to_sync(self.channel_layer.group_add)("appDel", self.channel_name) self.accept() self.render() appAlarm.py def appFunc(csvUpload): #csvUpload=pd.read_csv(request.FILES['filename']) csvFile = pd.DataFrame(csvUpload) colUsernames = csvFile.usernames print(colUsernames) channel_layer = get_channel_layer() for user in colUsernames: req = r.get('https://reqres.in/api/users/2') print(req) t = req.json() data = t['data']['email'] print(user + " " + data) message = user + " " + data async_to_sync(channel_layer.group_send)( 'appDel', {'type': 'render', 'message': message} ) It's throwing this error: async_to_sync(channel_layer.group_send)( AttributeError: 'NoneType' object has no attribute 'group_send' and will throw the same error for group_add when stripping it back more to figure out what's going on, but per the documentation HERE I feel like this should be working. -

Sending dictionary as Django model attribute
Is there any possibility to send some keyword: argument into django model attribute (one attribute)? I tried to use models.TextField for that but there must be better solution. from django.db import models class Newsletter(models.Model): start_datetime = models.DateTimeField() text = models.TextField(blank=True) filter = models.TextField() end_datetime = models.DateTimeField()
