I'm having some trouble using Python string functions on VARCHAR columns in
MySQL (reflected using automap_base() and base.prepare). I'm getting
AttributeError: Neither 'InstrumentedAttribute' object nor 'Comparator'
object associated with users.middlename has an attribute 'replace'
when I try
base_match = sess.query(md_users.id, abms_biog.id).\
filter(match().non_conflict_middlename(md_users.middlename,
abms_biog.middlename) == 1).
with my non_conflict_middlename function which just does some basic string
matching:
def non_conflict_middlename(self, a, b):
a = a.replace('.','')
b = b.replace('.','')
if ((len(a.strip()) == 0 or len(b.strip()) == 0)
or (a.replace('-','').replace(' ','') ==
b.replace('-','').replace(' ',''))
or ((len(a) == 1 or len(b) == 1) and a[0] == b[0])
or ((len(a) > 1 and len(b) > 1) and (a.find(b) + b.find(a) >
-2))
or (((' ' in a) and a[0]+a.split(' ',1)[1][0] == b) or ((' ' in
b) and b[0]+b.split(' ',1)[1][0] == a))
or ((('-' in a) and a[0]+a.split(' ',1)[1][0] == b) or (('-' in
b) and b[0]+b.split(' ',1)[1][0] == a))):
return 1
else:
return 0
Am I missing something here? Do I need to explicitly declare the tables and
data types with declarative base or can I somehow treat columns as Python
string objects while using reflected tables via automap? Thanks in advance
for your time!
