Question

symfony

good time of the day,
I get an error when saving to the database, how can I fix it?

Expected value of type "MyBundle\HotelBundle\Model\Pic" for association field "MyBundle\HotelBundle\Model\Hotel#$pics", got "NULL" instead.

Answer 1

you need to make the type for the pics field nullable=true and remove the strict typehint if it exists
