Query with sqlalchemy with and and or
First of all thank you for your help.
My problem is that I have to query the server with a lot of inputs. I am updating a web page that on the past only accept one input but now, i created a checkbox so the user can have more flexibility on the query:
query = session.query(table_name).filter(and_(*conditions) , or_(*multiple_choice_filter))
Where multiple choice is a list with letters like ["A", "B"]
And conditions are a list of conditions:
table_name.c.column_1.op('~*')(filter_1))
Where on the past, there weren't anything else apart from the initial conditions but now I want to add the checkbox.
Somebody now how to combine in the query the conditions from the past with the multiple_choice_filter?
Thank you!

I found how to do it.The point of my question is to chain AND with OR.
First, create the filters:
conditions =
for the and statement is very straight forward:
conditions.append(table_name.c.column_name_1.op('~*')(value_1))
conditions.append(table_name.c.column_name_2.op('~*')(value_2))
conditions.append(table_name.c.column_name_3.op('~*')(value_3))
query = session.query(table_name).filter(and_(*conditions)).order_by(table_name.c.column_name_1)
Which is translated to:
SELECT * FROM table_name WHERE (column_name_1 == value_1 AND column_name_2 == value_2 AND column_name_3 == value_3)
Now, to chain conditions with OR and AND:
We use two different variables: one for the AND statement (exactly like above) and another other one like the next one:
filter_or_1.append(table_name.c.column_name_4.op('~*')(value_4))# First possible value for the OR statement
filter_or_1.append(table_name.c.column_name_4.op('~*')(value_5))# Second possible value for the OR statement
filter_or_1.append(table_name.c.column_name_4.op('~*')(value_6))# Third possible value for the OR statement
and the query will be:
query = session.query(table_name).filter(and_(*conditions) , and_(or_(*filter_or_1))).order_by(table_name.c.column_name_1)
Which is translated to:
SELECT * FROM table_name WHERE (column_name_1 == value_1 AND column_name_2 == value_2 AND column_name_3 == value_3 AND(column_name_4==value_4 OR column_name_4==value_5 column_name_4==value_6 ))
