did you change your database manually (without migration) or mix migration files?

mix migrtion files

hi every one i have to give the user some ModelMultipleChoiceField() field but the thing i am using this to get the choices queryset=User.objects.all() and i but this in the form and in my template i do {{form}} but the problem is i got this error after i fill all the fields in the form !! "Cannot assign "<QuerySet [<User: test01>]>": "project.owner_name" must be a "User" instance."

You got an empty filter

i used filter but it dose not fix the problem i will try agin

You cant put a filter without criteria

Just try to run it in shell

Also, its not ok to use all() if you override the query, use none()

Also you may be mixing Form and ModelForm

In ModelForm you dont init manually the fields

Use Form i guess

thanks @hyunlee1o

mix migrtion files

most simple way is delete all migration file and your db, then makemigrations and migrate

does that break things? :O

nope

hmmm

i sometimes deleted a wrong migration file but deleting all :)

im just cautious

inconsistent migration files are what break migration

yeah, tru

i sometimes deleted a wrong migration file but deleting all :)

if you delete your db also then created table after next migrate should be fine

one thing i always thought is how to regen a col i deleted in database MANUALLY

Roleback first your migrate file and makemigration again

i wont recommend you to generate manually columns django auto generate, since django take care column relationship, type, etc

yes, many details

i think dump data, delete table and rerun migration best solution when your table and migration files not sync'ed

yes, also how to do it without messing up xD

if you already fix your migration files

Roleback first your migrate file and makemigration again

by doing this for example

or manually find one by one wheres the mistake (usually the migration file start with duplicate number)

then your next migrate will be fine

yes, i feel the tension when i do that but just asking how you do it

thanks

also dumping a table better through shell or using the GUI?

*may be a noob question*

i use dbeaver

but the gui is too much eclipse like and a bit buggy

yeah true, and its another app, delete via shell probably faster for almost any case

you should not put those things there tho. use fixture instead

fixture?

fixture?

read more about django fixture here

jsonture

not always json tho

yes, its nice, also you can save a table in a fixture

but tbh i hate manage py dumpdata for backup or work with many data. it give unsorted data so sometimes relationship breaks

but maybe its just me that dont know how to really use it. maybe someone here know how to avoid that
