Have you tried adding a format to your tables and defining your tables
using objects instead of 'reference...'?
I'm no web2py expert by any means, but I had a similar situation and when I
changed the reference for my foreign id to db.other_table instead of
'reference other_table,' the format defined for that table was used instead
of the id.
Something like this:
db.define_table('HumanLanguage',
Field('languageName','string'),
Field('forumLocations','string'),
Field('comments','string'),
format = '%(languageName)s'), # define a format
auth.signature)
db.HumanLanguage.languageName.requires = IS_NOT_EMPTY()
##
## Define DictionaryReferenceModel and WordReferenceModel above here
## DictionaryReferenceModel, WordReferenceModel should have a format
##
## Dictionary type means what category of dictionary is it? Medical,
computer,etc. There is one for each language.
db.define_table('DictionaryType',
Field('dictionaryName','string'),
Field('comments','string'),
Field('languageID',db.HumanLanguage ), # changed to object
Field('DictionaryReferenceModelID', db.DictionaryReferenceModel), #
changed to object
format = '%(dictionaryName)s', # define format
auth.signature)
db.DictionaryType.dictionaryName.requires = IS_NOT_EMPTY()
db.DictionaryType.languageID.requires = IS_IN_DB(db, 'HumanLanguage.id',
'%(languageName)s',zero=T('choose one'))
db.DictionaryType.DictionaryReferenceModelID.requires = IS_IN_DB(db,
'DictionaryReferenceModel.id', '%(DictionaryTypeID)s',zero=T('choose one'))
db.define_table('Word',
Field('wordName','string'),
Field ('definition','string'),
Field('languageID', db.HumanLanguage ), # changed to object
Field('dictionaryTypeID',db.DictionaryType), # changed to object
Field('wordReferenceModelID',db.WordReferenceModel), # changed to object
Field('comments','string'),
auth.signature)
db.Word.languageID.requires = IS_IN_DB(db, 'HumanLanguage.id',
'%(languageName)s',zero=T('choose one'))
db.Word.dictionaryTypeID.requires = IS_IN_DB(db, 'DictionaryType.id',
'%(dictionaryName)s',zero=T('choose one'))
db.Word.wordName.requires = IS_NOT_EMPTY()
db.Word.wordReferenceModelID.requires = IS_NULL_OR(IS_IN_DB(db,
'WordReferenceModel.id', '%(wordID)s',zero=T('choose one')))
