I have a model created in Django, simple one. I have updated the value of this model through the web page. Is there anyway to check the previous values of a certain ID?

Hahaha, you have to create a separate model or have a field that you'll copy data to before destroying it. You'll write a logic to do that.

if you've notice, you call YourViewClass.as_view() so, as you can see, you're calling the function .as_view() of the CBV, so yes, technically you can, but you're gonna break things if you don't know what you're doing 🤷🏻‍♂️ but, if you're asking that, it means you don't, so the short answer is: "NO"

I just tried and did it. Though i do not know if it is an ethical way... What i did is yourviewclass.myfunction

Hi guys, someone here use factory boy to populate fake data?, I mean, using factory boy as fixtures

I just tried and did it. Though i do not know if it is an ethical way... What i did is yourviewclass.myfunction

it has nothing to do with ethics but chances are that maybe you're writing unmaintainable code, so your future self (or another developer) will call on your mom 🤷🏻‍♂️

😂😂😂 ok dat was a good metaphor... So i will use an alternate way of creating a different function and using FBV

Oh I see, so once I do an update of a field, the previous value will be destroyed by default right? Dang it, I lost something important 😆 Anyway, thank you for the idea of how to keep backup this field!

I have two models. Students has name, class. Parents has name, one-to-one relation with Student. How do I access query set of students who's parent name= 'somename' ?

Hi, I want to ExtractDay from annotated field

.annotate( expire_days=F('expiration_date') - now))\ .values( days=ExtractDay(F('expire_days'))

But it doesn't work

How I should do it?

Annotation of expire_days works perfectly and add new field

Students.objects.filter(parents__name='somename')

I haven't added any parent relation in Student model Relation between them is in Parents model i.e one-to-one(Student)

So I was trying to get students query set from Parent's set

So I was trying to get students query set from Parent's set

What is related_name value of one-to-one field in Parents?

What is related_name value of one-to-one field in Parents?

It's 'student'

It should be name of Parent model in Student model. For example. If related_name is 'parent' then it will work like Students.objects.filter(parent__name='somename')

It should be name of Parent model in Student model. For example. If related_name is 'parent' then it will work like Students.objects.filter(parent__name='somename')

Ya but this won't be using the advantage of relation between them. Since name of parent is in parents table I want to get it using relation

It's 'student'

is 'student' the name of field in Parent or the related_name value of student field in Parent?

is 'student' the name of field in Parent or the related_name value of student field in Parent?

It is a field in the Parent. student = models.OneToOneField(StudentInfo,primary_key=True, on_delete=models.CASCADE)

Guys, can we create a telegram channel or slack channel with a curriculum for be a either back-end dev or full stack guy

@admin

It is a field in the Parent. student = models.OneToOneField(StudentInfo,primary_key=True, on_delete=models.CASCADE)

student = models.OneToOneField(StudentInfo,primary_key=True, on_delete=models.CASCADE, related_name='parent')

student = models.OneToOneField(StudentInfo,primary_key=True, on_delete=models.CASCADE, related_name='parent')

Did these changes to my model and tried Students.objects.filter(parent__fName='somename') since my name field in parent is 'fName' but got error— Related Field got invalid lookup
