Django sterilizer update method validated_data convertion
I am trying to update an instance of my model via the serializer update method. This modal have many to many connection to another model. my models: class GPX(models.Model): name = models.CharField(max_length=255) created_date = models.DateField(auto_now_add=True) updated_date = models.DateField(auto_now=True) trail_types = models.ManyToManyField(TrailTypes, blank=True) class TrailTypes(models.Model): name = models.CharField(max_length=100) def __str__(self): return self.name I want to get has input a list contain trail_types names instead of their ids. The problem is that Django converts the data objects of trail_types and then pass it as validate_data to the update method under the seralizer. How can I do the conversion before? or is there another way to specify to Django to create trail_type objects by its name. @transaction.atomic def update(self, instance, validated_data): gpx: GPX = super().update(instance, validated_data) return gpx thanks in advanced -

Django model validation in clean or in separate validators?
I am pretty new to Django and I was wondering what is the best method to validate your models in Django? Are there any advantages to using clean vs adding validators to your models? By validators I mean when you do declare the field, populating the validator=[] list. I find the models to be easier to read with the validators in another package, and declared in the field list. Also, I try to validate the data before in services, before initializing the models. What do you think / prefer? Thanks a lot. -

The number of rows after narrowing-down

setAttribute also also setting the value for the following element

In my HTML, I have a button that should send a few values to a Javascript function. The javascript function should then find and update some divs in the HTML.

Runtime Foreign Key vs Integerfield
I have a problem. I already have two solution for my problem, but i was wondering which of those is the faster solution. I guess that the second solution is not only more convienient- to use but also faster, but i want to be sure, so thats the reason why im asking. My problem is i want to group multiple rows together. The group won't hold any meta data. So im only interested in runtime. On the one hand i can use a Integer field and filter it later on when i need to get all entries that belong to the group. I guess runtime of O(n). The second solution and probably the more practicle way would be to create a foreign key to another model only using the pk there. Then i can use the reverse relation to find all the entries that belong to the group. -

How to define models in django that provides custom values based on pre-selection for a field?
Given the following model that stores the user's wish list for reading books: class ReadingList(models.Model): user_id = models.ForeignKey(UserInfo, on_delete=models.DO_NOTHING, null=False, blank=False, default=None, db_column='user_id') book= models.CharField(max_length=255, blank=False) creation_time = models.DateTimeField(blank=True) class Meta: unique_together = (('user_id', book),) I want to create a model that helps in tracking the time spent in the reading the book on different days which looks something like this: class ReadingTracker(models.Model): user_id = models.ForeignKey(ReadingList, on_delete=models.DO_NOTHING, related_name='user', blank=False, db_column='user_id') book= models.ForeignKey(ReadingList, on_delete=models.DO_NOTHING, related_name='book-to-read', blank=False, db_column='book') time = models.DateTimeField(blank=True) time_spent = models.floatfield() On the client-side (corresponding to ReadingTracker) for both the fields user_id and book I see that ReadingList object (1), ReadingList object (2), ... are listed. But, this is not working as expected. What I want to achieve are the following: For user_id field I want to see the something like dummy_uid1, dummy_uid2, ... to be listed. Consider dummy_uid1 wants to read book1 and book2 whereas dummy_uid2 wants to read book1 and book3. When dummy_uid1 is selected as user_id, I want only book1 and book2 to be listed for selection. How do I define the model in django rest framework to achieve this? Any suggestions related to the above would be much appreciated and thank you in advance.
