Table definition:
tables['indicators'] = Table('indicators', metadata, autoload=True)
tables['indicatorgroups'] = Table('indicatorgroups', metadata,
autoload=True)
##indicatorgroups table has two columns: idindicatorgroup, name
##indicators table has several columns: idindicator, idindicatorgroup(FK),
...
Mapper:
mappers['indicatorgroups'] = mapper(IndicatorGroups,
tables['indicatorgroups'])
mappers['indicators'] = mapper(Indicators, tables['indicators'],
properties = {
'idindicatorgroup' :
relation(IndicatorGroups),
},allow_column_override=True)
Once i do this I have create a method in order to insert data in my mySQL
db:
class Insert:
implements(IInsert)
def insert(self, file):
import pdb
db = getUtility(IDatabase, name='db.query')
session = db.session
sniffer = csv.Sniffer()
dialect = sniffer.sniff(file.read())
file.seek(0)
csvReader = csv.reader(file, dialect=dialect)
csvReader.next()
for i in csvReader:
group, subgroup, indicator, code = i
indg=IndicatorGroups()
indg.name=group
session.save(indg)
ind=Indicators()
ind.code=code
ind.name=indicator
ind.idindicatorgroup=indg
session.save(ind)
session.flush()
but when execute session.flush() I have this error:
