Hello guys, could you please advise how to make indication of Date and Time in datebase when new object was created, currently field Date_Pub = models.DateTimeField(auto_now_add=True), but after a form was submitted - all fields in adminpage filled up except Date_Pub field, how to fix? thanks.
You can use signals to perform a post_save operation. You can update the values of any variable specified in your model.

Not really well tested in Django, version 2.1 broke everything, the only solution was to drop the database or fix its schema by hand
How about using an old version of django to dump to json and then migration with new version?
Rohan
Or that's what you're calling fixing schema with hand?

You had to manually fix the table references as they were pointing to not existing tables.

hi, somebody uses TinyMCE-4-lite as editor ?
Gourav
Obviously
Gourav
U have excluded all there options😂😂
Gourav
Try other framework
Gourav
React or vue etc..
But i'm not sure about their speed as i didn't use them much
Mirco
Gourav
But they render differently
Mirco
The fetching stuff is basically the same
Gourav
Uses DOM manipulation
Mirco
Whatever u want but that doesn't change the speed of pending request while fetching
Gourav
But much effective than regular js
Gourav
Try both
Gourav
How can i predict??😂😂😂😂
Mirco
Instead of thinking about frontend libraries etc. , spend more time on backend staff
For example the objects.all() could be used with a prefetch or select_related and speed up query to db
Gourav
What's the problem with pagination exactly
godmode
Nobody uses tinymce4 for django?
Ricardo
a good idea is first identify from where the slow is coming, database query, html rendering, js framework
Ricardo
without knowing where is the bottleneck you will not manage to find a good solution other them by blind luck
Ricardo
fyi, i just rendered 4000 objects and it took 7seconds, so you probably need to check your database queries, maybe prefetch_related as stated above can help you

Hey guys, when i ask for a object in a view if that object got an ForeignKey but the value of this Foreign Key haven't been set yet... if i want the objects which doesn't got the ForeignKey set should i ask for Model.Objects.get(foreign_field=None)?
godmode
Better example, i got a list of questions and a model for question an another for answers, if i want a list of questions without answer should i ask for all these questions which got the field answer (It's a Foreign Key) with the value None?
godmode
For example i know in Java is Null... in python?
