Hi people !
Whenever i create a date or datetime field in entity python always gives
me an exception:
"NameError: name 'date' is not defined" for "date = Required(date)"
record according your documentation documentation
"pony.orm.core.ERDiagramError: Entity definition date was not found" for
"date = Required('date')"
I am trying to run i file with folowing code:
#!/usr/bin/python
# -*- coding: utf-8 -*-
from pony.orm import *
db = Database('sqlite', 'db.sqlite', create_db=True)
class subscribers(db.Entity):
id = PrimaryKey(int, auto=True)
email = Optional(str)
date = Required(date)
sql_debug(True)
db.generate_mapping(create_tables=True)
Running that code from python shell gives me the following:
>>> from pony.orm import *
>>> db = Database('sqlite', '/tmp/db.sqlite', create_db=True)
GET NEW CONNECTION
RELEASE CONNECTION
>>> class subscribers(db.Entity):
... id = PrimaryKey(int, auto=True)
... email = Optional(str)
... date = Required('date')
...
>>> sql_debug(True)
>>> db.generate_mapping(create_tables=True)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<auto generated wrapper of generate_mapping() function>", line 2, in generate_mapping
File "/usr/local/lib/python2.7/dist-packages/pony/orm/core.py", line 2698, in _resolve_attr_types_
throw(ERDiagramError, 'Entity definition %s was not found' % py_type)
File "/usr/local/lib/python2.7/dist-packages/pony/utils.py", line 126, in throw
raise exc # Set "pony.options.CUT_TRACEBACK = False" to see full traceback
pony.orm.core.ERDiagramError: Entity definition date was not found
So database can't be created after all.
Pony version installed with pip:
pony - Pony Object-Relational Mapper
INSTALLED: 0.5.1
LATEST: 0.5-beta
Is it a bug or something? How i should create a datefield with Pony ?
I've couldn't create a table with several tables with Pony until i
commented out all datefields strings from the code. So Pony works if i
don't use datetime fields.
