AGh..tilename was in it, I just didnt include it in this thread:
db.define_table('supplier',
Field('suppliercode'),
Field('suppliername'),
format='%(suppliercode)s')
db.supplier.suppliercode.requires = IS_NOT_IN_DB(db,db.supplier.suppliercode
)
db.supplier.suppliername.requires = IS_NOT_IN_DB(db,db.supplier.suppliername
)
db.define_table('series',
Field('supplier','reference supplier'),
Field('seriesname'),
Field('seriesdescription'),
Field('description'))
db.define_table('product',
Field('series', 'reference series'),
Field('supptile',represent=lambda id, r: '%s%s'% (r.supplier.suppliercode
,r.tilename)),
Field('tilename'),
Field('description'),
Field('conversiontype'),
Field('inactive','boolean'))
controller function:
grid = SQLFORM
<http://127.0.0.1:8000/examples/global/vars/SQLFORM>.grid(db.series,left
=[db.series.on(db.series.id==db.product.series),db.supplier.on(db.supplier.id==db.series.supplier)],fields=[db.supplier.suppliercode,db.product.supptile,db.product.tilename],
headers = {'supplier.suppliercode':
'SUPPLIERCODE','series.supptile':'ITEMCODE','product.tilename':'REORDER#'})
As it is, the grid works as I want. I get the supptile which is a
concatenation of the suppliercode and tilename. When I go to database
administration, which I use, the product table prompts me an error. Agh!!!
Thanks so much Anthony!
**I hope I didnt miss anything**
