Best way to modified third party app database restrictions?

[Yongky Tria Putra]

Hello everyone,

What is the best way to modified database field restrictions in third party app (pretix)? Currently, i want to change max_digits=7  to max_digits=9  in database below.

default_price = models.DecimalField(

decimal_places=2, max_digits=7,

null=True, blank=True,

verbose_name=_("Default price"),

)

Is it possible without modified the third party source code?

Thanks

Try to set default_price.max_digits=9

Or you can create your own class extending DecimalField setting your defaults.

I solve it with this two lines code in my models:

from thirdparty.models import ParentModelClass
ParentModelClass._meta.get_field('default_price').max_digits = 9

then makemigrations && migrate

voila it work, but i don't know any downside using this tricks.

Hope it will help others with similar situation as well.
