The default profile that i have put in the image field doesn't work in Django
I have a Custom User model which has an image field, I have as well added a default option and have given a default option but the user doesn't seem to be using the default option anytime I render it onto the templates. I have observed that only when I add an image onto it, it works but it doesn't use the default if there is not image in it.

Django Models - Lead Model
Good day. I am busy with a small project on creating a django leads crm. The first user story is as follows: When a user logs onto the website - they will complete a short form. Once submitted all leads will be sent to a default (listview) showing all leads. Leads will then be allocated by the manager to individual agents. As such leads will have an initial(default category) of 0 i.e. is_unassigned, once assigned the lead_category must change to 1 i.e. is_assigned. This can be either int type fields or just boolean fields. What would be the best representation of this model? This is the current model I have. models.py class Lead(models.Model): first_name = models.CharField(max_length=20) last_name = models.CharField(max_length=20) lead_source = models.CharField(max_length=20, null=True) def __str__(self): return f{self.first_name} {self.last_name} class LeadAssigned(models.Model): pass Is it best that I create a boolean field or would I create a seperate model showing LeadAssigned? -
Django Suspicious File Operation when including ReactJS's build/static in STATICFILES_DIRS
My settings.py STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATIC_URL = '/static/' STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage' STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'build', 'static'), os.path.join(BASE_DIR, 'src/static') ] MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' I'm following this guide to put my app on heroku, but I'm running into problem when doing python manage.py collectstatic The error is: django.core.exceptions.SuspiciousFileOperation: The joined path (/path/to/root_folder/static/media/file.jpg) is located outside of the base path component (/path/to/root_folder/staticfiles) What's strange is that there's no place that mentions static/media in my app, except in the build/asset-manifest.json and some css files in static/css/ I'm wondering how the /path/to/root_folder/static/media/ is from and how to fix it None of the previous posts I've found solve my problem. If you can link one, that'd be great too -
Why request.user == 'admin' conditional statement not working in Django3 views.py?
I am currently logged as 'admin' in my django3 project. As 'admin', I have to display all the books. But the if-else statement in the views.py is not recognising the 'admin' and always goes into the else section of the conditional statement. def book_list(request): print ('Currently logged as ', request.user) if request.user is 'admin': print ('All') books = Book.objects.all() else: print ('Filter') books = Book.objects.filter(author=request.user) return render(request, 'mtsAuthor/book_list.html', { 'books': books }) When I refresh the page as an 'admin', the following custom debug messages are seen in the terminal. Hope the same shall help to troubleshoot.

Django language_cookie domain cannot be changed
So there is a poroblem. I need to change domain for my site until I use eg. ab.user.localhost ac.user.localhost My language cookie with default name 'django_language' has domain accordingly set to host: ab.user.localhost or ac.user.localhost depends on which of these two urls you currently are. I want to have this cookie domain set for all subdomains to: .user.localhost So I used in my django settings.py like https://docs.djangoproject.com/en/2.2/ref/settings/#language-cookie-domain LANGUAGE_COOKIE_DOMAIN = '.user.localhost' But still.. After clearing cookies django_language cookie has ab.user.localhost domain or ac.user.localhost domain set. Any idea why this is not working? -
Django-allauth - Custom Sign Up with OneToOneField

How to populate html input in Django framework without using a any of Django form?
I'm implementing an HTML table that is populated with information as the page is rendered. I cannot use a form here but still, I need to embed some common input controls to certain s in that HTML table (selection boxes). So I think the data itself can be passed to the template as the page is being rendered but do I need to use javascript to fill the controls? I think I cannot use anything related to forms here. I have implemented a javascript ajax code to get the data when the table is filled by a user. That is working perfectly. But the user does not fill everything on that table but there must be some selections done before the data can be submitted. That data is read from the database, delivered to the HTML table for the user to make a selection. But I have never used HTML inputs other than in Django forms. Or is there a better solution to achieve this? -
Install Postgis and Postgres for Django (windows)
I'm trying to use Postgis along with my Django website and Postgres database. I got Postgis, Django and Postgres installed already on my Windows 10 setup. Now whenever I attempt to run a 'makemigrations' for my models making use of types such as 'Geometry' I got errors saying it's unable to find GDAL. I understand from the documentation you have to install 3 packages before being able to use Postgis; GEOS, PROJ.4 and GDAL. Is this necessary? Whenever I look at the installation guide it seems to be for Linux systems and there's no mention of Windows 10. I'm able to perfectly fine use my databases through the pgadmin interface with Postgis to plot and view lines etc, but Django wont play ball. Does anyone have an idea how to make Postgis work for Django, or do I have to switch to Linux to get the required packages even though I already have them installed through pip installer. Any help is appreciated. Thanks -
Django Admin overwrite the __str__ method in an autocomplete_field
I want to overwrite the __str__ method in Django admin when using the autocomplete_fields = () but the returned values are using __str__. I have a form something like class MyAdminForm(forms.ModelForm): placement = forms.Select( choices = Organisation.objects.active(), ) class Meta: model = Lead fields = '__all__' def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['placement'].label_from_instance = lambda obj: f'{str(obj)} {obj.post_code}' This will provide back a Select with the organisation name and post code in the dropdown fields. But there are some 80k choices so I need to using autocomplete. Within within admin.py I have class LeadAdmin(admin.ModelAdmin): form = LeadAdminForm autocomplete_fields = ('placement',) As soon as I add the autocomplete_fields I lose my postcode and it reverts to just showing the __str__ Hoa can I used autocomplete_fields and overwrite the __str__ method? -

Set default option in select element and load data
On my html-template I got a select-element looking like this: <select class ="form-control", id="categories"> {% for c in categories %} <option value = {{c.id_category}}>{{c}}</option> {% endfor %} </select> Where the user can choose one of the avaiable categories and with javascript the according database entries of that category get loaded in to a table on the site. $(document).ready(function(){ $("#categories").change(function(e){ ... The script only gets active when one uses the dropdown menu. At the moment if you first access the site no data will be shown by default. What I want it to do though is, that by default one of the categories (doesnt really matter which) is selected and the corresponding data is shown. If I simply use 'selected' for one of the options no data will be in the table (obviously, cause the JS doesnt register a change of a selected option). So how can I do this? -

Django channels - how to send messages to groups from an external script?
I have a very simple Django channels consumer that subscribes clients to a group: class TestConsumer(AsyncJsonWebsocketConsumer): async def websocket_connect(self, event): await self.accept() await self.send_json('Connected') await self.channel_layer.group_add( 'GROUP1', self.channel_name ) async def websocket_receive(self, event): pass async def websocket_disconnect(self, event): await self.channel_layer.group_discard( 'GROUP1', self.channel_name ) And then, in the same server but outside of the Django application, i have a script that receives data from a websocket server: import asyncio import websockets async def hello(): uri = "ws://SOME-URL" async with websockets.connect(uri) as websocket: data = await websocket.recv() print(json.loads(data)) Is there any way i can send the data received in the second script to users subscribed to GROUP1 in the Django Channels app? So basically every time the second script receives a new message, that message must be sent from the Django Channels app to its clients. For various reasons i can't run the second script in a Django management command, is there another way to do this? -
