I have a custom form that allows users to save information on what they are
selling but the problem is that at times customers save similar items names
and during a search by buyers the buyer gets a duplicate name results, what
i want is to disable registering clients from saving the same item names,
if the name they want to save is already in the database they should get a
message that says, *"that name is already used, please choose a different
name for your items" , *what would a custom validator that does this look
like? Below is my APP code.
*MODEL*
db.define_table('black_market2',
Field('regCode', requires=IS_NOT_EMPTY()),
Field('fullNames', requires=IS_NOT_EMPTY()),
Field('id_number', 'integer', requires=IS_NOT_EMPTY()),
Field('contactNumber', requires=IS_NOT_EMPTY()),
#Field('place', 'reference locations'),
Field('geographical_place', requires=IS_NOT_EMPTY()),
Field('located_at', requires=IS_NOT_EMPTY()),
Field('product', requires=IS_NOT_EMPTY()),
Field('model', requires=IS_NOT_EMPTY()),
Field('productionYear', requires=IS_NOT_EMPTY()),
Field('productSerialNumber', requires=IS_NOT_EMPTY()),
Field('offerPrice', requires=IS_NOT_EMPTY()),
format='%(product)s')
