<s>[INST] What's the difference between filter and filter_by in SQLAlchemy? Could anyone explain the difference between filter and filter_by functions in SQLAlchemy? I am confused and can't really see the difference. Which one should I be using?
 [/INST] filter_by is used for simple queries on the column names like
db.users.filter_by(name='Joe')
The same can be accomplished with filter by writing
db.users.filter(db.users.name=='Joe')
but you can also write more powerful queries containing expressions like
db.users.filter(or_(db.users.name=='Ryan', db.users.country=='England'))
