^set blank=True, null=True also

even if you change those params to False it will work, but with different behavior. so make sure you know what you need

I have changed it to auto_add_ now = true

harisai | హరి సాయి

But showing the same error

inchidi

you access the data directly from db, no python there while default=timezon.now() is python code

harisai | హరి సాయి

okay got it.

inchidi

okay got it.

when you work with django make sure you do anything to db via python manage.py shell, not touching db directly will save you from many bad things

Sure thanks.. I'm new to django can you suggest me best website to learn django..

inchidi

you already on good track imo, just make sure you check the docs oftentimes

harisai | హరి సాయి

set auto_now_add=True similar with above but you cant pass other value, and its uneditable (the cell will always store timestamp when the row created)

this is working but i only need date out of it not the time how can i get that

I want to insert bulk vales

Javi

Yes, that is what bulk_create does

You can use Update if you want to update previously created obiects

Hi guys, a question If I define a class , (and Its NOT a model class) , may I make a object like queries results from another model class to do a join query? I want to make a app where you insert some info, and mix it with database values; both datasets are houry values

Hmmm

Anonymous

I am not able to understand your problem.

Javi

me neither :/

Ismael

i try do explain in other way

Ismael

I have a model like this class Prices(models.Model): ___Price ___Hour (1-24) ___Date And my app client sends data for Date-Hour_quantity buyed class Quantity(): ___Volume ___Hour ___Date

Ismael

I dont want to upload each client data

Ismael

just take it, and valorate, Price * Volume per hour and day

Ismael

and my question is if I can make something like a "join query" with the no-database-class and the database-class

Javi

maybe I'm not taking the idea correctly, but you can use the quantity class to build the query.

Javi

You can even create a custom manager that takes the Quantity as input and builds the query there, so you have to write the code only once

Ismael

my idea is to do something like a "temporary table"

😼

I would suggest a temporary chair

Ismael

I would suggest a temporary chair

Tnx, I suggest you use a contemporary ideology
