Re: [SQLObject] Problems with str() on SQLObjects

[Simen B. <si...@lu...>]

I get this message afer it's been looping for a while:

RuntimeError: maximum recursion depth exceeded

The code producing it is a function called xmlrepr which basically takes
some basic python types and turns them into an xml document:

-- BEGIN xmlify.py --
from types import ListType, DictionaryType, InstanceType

def xmlrepr(object, name):
 if type(object) =3D=3D ListType:
  xml =3D "<%s>" % name
  for item in object:
   xml+=3D xmlrepr(item, "item")

  xml =3D xml + "</%s>" % name
  return xml

 elif type(object) =3D=3D DictionaryType:
  xml =3D "<%s>" % name
  for (key, value) in object.items():
   xml+=3D xmlrepr(value, key)

  xml =3D xml + "</%s>" % name
  return xml
 else:
  return "<%s>%s</%s>" % (name, object, name)
-- END xmlify.py --

The code invoking this is here:

-- BEGIN Main.py --
 def list(self):
  """Lists the current entries."""
  entries =3D []
  for entry in Entry.select('all'):
   entries.append(entry.content())

  self.model =3D entries
-- END --

Where Entry is an SQLObject:

-- BEGIN entry.py --
class Entry(SQLObject):
 _columns =3D [IntCol('date', default=3DNone), Col('content', =
default=3DNone),
IntCol('mood', default=3D5)]
 _connection =3D SQLiteConnection('C:/Home/Projects/blog/blog.db', =
debug=3D1)

 def content(self):
  return {'date': self.date, 'content': self.content, 'mood': self.mood}
-- END entry.py --

Hope that helped :)

only happens to Col() or StringCol() types, IntCol() works fine.
