Hey.. If any one can help,
I wanted to make a form where there are fields from different table linked by foreign key
Form has drop downs which are dependent on each other(fields from different model - foreign key)
In a way that when we select one field ,the next dropdown should be filled according to previously selected dropdown.
Is there any fast way of creating such form in django?

I think you are using pip instead of pip3
Try using pip3

python 2 is dead
Not in 2years time.
It will still be in use.
I work on enterprise systems that depends heavily on python2 for the CLI.
It will take years to switch to py3.
There are several companies that will still receive support for the next 5years
Ghorz
Google, Instagram and a host of others still run python2.

Even Letsencrypt Certbot SSL is still using py2 till date

come on @Ghorz , I know but Viswa is working with a fresh project by using py2 😅

Vishnu
Mirco
Bro I please check this
https://docs.djangoproject.com/en/2.2/ref/validators/#fileextensionvalidator
Django has already built-in what u r looking for
Mirco

subtype indicates the partition subtype. It can be integer, date etc.

If not csv_file.name.endswith('.csv'):

If the given file is not a csv file it should print the error message Naa,

I've already answered you this morning, study Django Validators and you don't have to write the check into the view
Vishnu
Bro but I'm passing a primary key within that so that's the reason I was using it inside the view
Vishnu
Like if u look my views page you can understand
Vishnu
Without that I can't upload the contents in the csv file
Mirco
Bro but I'm passing a primary key within that so that's the reason I was using it inside the view

and I ask you the same thing of this morning
do you know what a Django validator is ?
Mirco
and how can you use it in a Model ?
Vishnu
