Saving Django form displayed on template like {{form.item}}
Django beginner here. I'm trying to understand something : In my template if I'm rendering my form like this {{form}} and click my button <button name="button" type="submit" onclick="">Save Form</button> The form is correctly saving.

I want to specifically change the color of nav-link active class here. How do I go about it? Is there any issue with any declaration here and the way it is framed?

If possible, please also suggest me a way to go around managing the page structure of Django Dash wherein how do I configure the page setup if I am uploading Django dash set up directly in html template? Thank you! Color does not change. If other items on vertical tabs get selected, they change color but not the main first tab. -

Django select_related() and prefetch_related() don't solve N+1 problem with nested objects
I'm trying to solve N+1 problem right now. I'm aware of select_related() and prefetch_related() methods but unfortunately the query I'm requesting to DB still not efficient enough. I have Comment model which has ForeignKey/M2M relations. class Comment(models.Model): profile = models.ForeignKey(Profile, related_name="comments", on_delete=CASCADE) post = models.ForeignKey(Post, related_name="comments", on_delete=CASCADE) parent = models.ForeignKey("self", related_name="children", blank=True, null=True, on_delete=models.CASCADE) reply_to = models.ForeignKey("self", related_name="replies", blank=True, null=True, on_delete=models.CASCADE) text = models.TextField(max_length=350) liked_by = models.ManyToManyField(Profile, related_name="comment_likes", blank=True) Comments system has just two-level layout (root comment and replies). But whenever I perform a query : comments = ( Comment.objects.filter(parent=None) .select_related("profile__specialization", "post", "parent", "reply_to") .prefetch_related("liked_by") .annotate(likes_count=Count("liked_by", distinct=True)) .order_by("-date_published") ) I'm still getting over 50 queries against DB to fetch profiles, posts etc. Even I remove select_related() and prefetch_related() at all I still get just 4-5 queries more. Serializers I use are just normal model.Serializer (requirements of a project pattern): class CommentDTOSerializer(serializers.Serializer): id = serializers.IntegerField(required=False, read_only=True) profile = ProfileBaseDTOSerializer(read_only=True) post = PostBaseDTOSerializer(read_only=True) parent = BaseCommentDTOSerializer(read_only=True) reply_to = BaseCommentDTOSerializer(read_only=True) children = BaseCommentDTOSerializer(many=True, read_only=True) text = serializers.CharField(read_only=True) liked_by = ProfileBaseDTOSerializer(many=True, read_only=True) likes_count = serializers.IntegerField(read_only=True) I can't get what is wrong with my prefetching and why all the nested models (profile, post, parent, reply_to) are not prefetched correctly and still require DB to perform … -

Use phone number / sms token instead of username password in django
I'm new to django and I'm developing a website with django, but I want to have a custom flow for register/login instead of django's default, as described below: When a user want to login/register redirects to a form that only have one field "phone number" and a submit button in the next page if the phone is belongs to a registered user, user receive a token via SMS and enter it to complete login. and if the phone isn't found, redirects to a form to receive user's information such as first/last name and SMS token to complete registering user. I know I need custom forms and custom user model, but I don't know how to implement this. Do I need to subclass my custom user model from django's AbstractUser or AbstractBaseUser? Do I need to use any plugin? Should I write a custom authentication backend? what should I do, if i want to differ between staffs and customers. So staff should login with username/password and customers use system described. I browsed some topics and tutorial about django user system and official document of django, but I feel confused and can't find my way. -

Simple Example of Multiple ManyToMany Model Relations in Django
I'm writing a workout app and have a number of models that need to link together. Specifically, I have an Exercise model that needs to track the name of each exercise as well as the primary and secondary muscle groups targeted by the exercise. I also need a muscle group model, and these all need to link together in a ManyToMany fashion, e.g. any muscle group be associated with the primary and/or secondary or multiple exercises and vice versa. How do I write the code to define the classes, as well as write a script to populate the database and test how to access various fields? Answered below as hopefully a useful super intro tutorial for others since I couldn't find something so easily online. -
