To check if a field is dirty we can simply use
fromPHP()
function of the mongodb driver. Besides, we shouldn't use the SQL-specific logic ofIlluminate\Eloquent\Model::originalIsEquivalent()
for mongodb. In sql, fields keep their schema data types and changing integer 1 to string '1' actually does nothing. However, in mongodb fields accept their types as they are inserted/updated. Therefore, if we change value of a field from(int)1
to(string)'1'
we actually must regard it as dirty.This change is backward incompatible. Don't know if anyone likes the current behaviour more.
