Hi,
By keeping the same name, you can modify existing SQL constrains via custom modules.
For example, if you need to change below constrain
_sql_constraints = [
( 'positive_color' , 'CHECK(color >= 0)' , 'The color code must be positive!' )
] In your custom module,
_sql_constraints = [
( 'positive_color' , 'CHECK(color > 0)' , 'The color code must be greater than zero!' )
]
Thanks
