Can I track and commit without push?
What I'm trying to do is to version a file without ever pushing it to github, is it something I can do ? Context : For instance, I have a local database for dev (Django) which is SQLite3 which creates a file "db.sqlite3". I don't want this file to be on github, but I'd like to be able to reset it to previous version if I mess with the migrations for example. Maybe they are better ways than git, I'm open to suggestions. Thank you ! -

Difference between creating custom Django token generator and using the default PasswordResetTokenGenerator
I'm creating a verification email users app, which as the name may suggest verify users' emails before activating their accounts. I've seen in many tutorials that they use the following code to create a custom token generator for account activation: class AccountActivationTokenGenerator(PasswordResetTokenGenerator): def _make_hash_value(self, user, timestamp): return text_type(user.is_active) + text_type(user.pk) + text_type(timestamp) token_generator = TokenGenerator() However, I don't see why I should use this over the default PasswordResetTokenGenerator. I've tried to implement both, the custom and the default and the result is the same. Why do they suggest inheriting PasswordResetTokenGenerator and create an AccountActivationTokenGenerator. Is there any security issue if I use the same token generator for two tasks? -

Django: Can't fetch records for the current date
I know you might be thinking that this is some stupid & trivial question by reading the heading but I can't make it work. I have one model called Survey which has one field called survey_date which is of type DATE. What I want to do is that fetch all the records by today's date & I really don't know why this easy looking thing became the pain in the a**. The simplest way I tried was this, def get_initial_queryset(self): today = datetime.date.today() qs = Survey.objects.filter(survey_date=today) print(qs.query) return qs I thought this should work but it did not, So tried googling it and found this Query datetime by today's date in Django It was very similar to my problem but believe me I tried every single answer from it and nothing worked. I even tried to get the actual query from the queryset I tried to run it manually via phpmyadmin but it returned no rows.I am pasting that generated query also here(I made it little shorter by removing other columns), SELECT `survey`.`id`, `survey`.`uid`, `survey`.`currency`, `survey`.`survey_type`, `survey`.`survey_subtype`, `survey`.`transit_type`, `survey`.`survey_date`, `survey`.`survey_time`, `survey`.`live_survey_type` FROM `survey` WHERE `survey`.`survey_date` = 2021-08-17 Any help would appreciated.I am using Django version 3.1.6. -
How to auto populate a read-only serializer field in django rest framework?
I have a question regarding django rest framework. Most of the time, I have a serializer which has some read-only fields. For example, consider this simple model below: class PersonalMessage(models.Model): sender = models.ForeignKey(User, related_name="sent_messages", ...) recipient = models.ForeignKey(User, related_name="recieved_messages", ...) text = models.CharField(...) def __str__(self) -> str: return f"{self.text} (sender={self.sender})" In this model, the value of sender and recipient should be automatically provided by the application itself and the user shouldn't be able to edit those fields. Alright, now take a look at this serializer: class PersonalMessageSerializer(serializers.ModelSerializer): class Meta: model = PersonalMessage fields = '__all__' read_only_fields = ('sender', 'recipient') It perfectly prevents users from setting an arbitrary value on the sender and recipient fields. But the problem is, when these fields are marked as read-only in the serializer, the serializer will completely ignore all the values that are passed into the constructor for these fields. So when I try to create a model, no values would be set for these fields: PersonalMessageSerializer(data={**request.data, 'sender': ..., 'recipient': ...) # Won't work What's the best way to prevent users from setting an arbitrary value and at the same time auto-populate those restricted fields in django rest framework? -
Django error when trying to migrate models with foreignkeys that don't have null=True or default set
I have this model that is a post like on Twitter, that has a creator. I'd ideally like the post to always require a creator_id and if the creator gets deleted then delete the post as well class Post(AbstractBaseModel): creator_id = models.ForeignKey(User, on_delete=models.CASCADE, related_name="post_creator_id") body = models.CharField(max_length=511) Whenever I try to run 'python manage.py migrate' I get this error "You are trying to change the nullable field 'creator_id' on cheerpost to non-nullable without a default; we can't do that (the database needs something to populate existing rows)." The options to solve this are are 1) provide a one off default or 2) ignore for now. Neither of these seem to fulfill my constraint that I want to enforce, which is creator_id must exist and is the person who created the post or the entity gets deleted. -
How does a django project use multiple databases with the same structure to read and write, distinguished by url
I have a django project and want to divide it into multiple databases with the same structure. Use url to distinguish different databases. When the admin management page logs in, log in to different databases according to different urls. For example: 127.0.0.1/admin uses the admin database, 127.0.0.1/admin2 uses the admin2 database. Does django implement this function? What do I need to do, Can you give me some suggestions or ideas? thank you very much -

Input Variable for Slice in html Forloop - Django

The input will basically fill a variable in the slice values and define it that way. I have been working on this for a long time with no luck, It is very far beyond me. Any help is greatly appreciated. Thanks! -
STUN/TURN server configuration for Django channels with WebRTC
I developed using django channels to implement video chat and message chat.(I was referring to a YouTuber's course.) When I first completed the development, I noticed that webrtc works only in the local network, and I found out that a stun/turn server was needed. So, I created a separate EC2 and built the stun/turn server and set this to the RTCPeerconnection in the web server. Stun/turn server test in Trickle ICE is good. But My video call still works only within the local network. And even within the same network, the connection was very slow. Server overall configuration.(Webserver with SSL application loadbalancer) Coturn config # /etc/default/coturn TURNSERVER_ENABLED=1 # /etc/turnserver.conf # STUN server port is 3478 for UDP and TCP, and 5349 for TLS. # Allow connection on the UDP port 3478 listening-port=3478 # and 5349 for TLS (secure) tls-listening-port=5349 # Require authentication fingerprint lt-cred-mech server-name=mysite.com realm=mysite.com # Important: # Create a test user if you want # You can remove this user after testing user=myuser:userpassword total-quota=100 stale-nonce=600 # Path to the SSL certificate and private key.
