Share the code with pastebin, it's easier to understand what you're trying to do
George
Nope
Jimmies San
share code :)
George
Each time i did an insert django tried to save on a primary key 1, 2, etc
George
I cant share the code but its nothing special
George
But primary keys 1,2,3 where already used so till the fourth insertion it didnt work
George
Mind a model with a single name field, a view that pics the form and saves my name field.
Jimmies San
But primary keys 1,2,3 where already used so till the fourth insertion it didnt work
what db are you using?
George
Postgresql
Jimmies San
how you generate pk?
George
Automatically i guess

George
But i inserted manually some values
George
The pk is generated by django
George
Should it check what is the last pk used?
Jimmies San
should. yes.
Jimmies San
but we don t know your env and your code.... check log debug . of db too
George
Hum ok
George
My env ok

SPARK_LOCAL_IP="<IP address>"
