I am working on the implementation of a search on zip-code.
The model:
db.define_table('company',
SQLField('name', length=54, default='', notnull=True),
SQLField('kvk_nummer', length=8),
SQLField('subdossiernummer', length=4, default='0000'),
SQLField('status', length=1, default='0'),
migrate=False)
db.define_table('address',
SQLField('company', db.bedrijf, default='', notnull=True),
SQLField('street', length=42),
SQLField('number', length=6),
SQLField('zip_code_digits', type=integer, length=4),
SQLField('zip_code_letters', length=2),
SQLField('city', length=42),
migrate=False)
db.define_table('zipcoderegions',
SQLField('region', type=integer, length=2, default='',
notnull=True),
SQLField('min', type=integer, length=4, default='', notnull=True),
SQLField('max', type=integer, length=4, default='', notnull=True),
migrate=False)
Values in the zipcoderegions table are:
73 7300 7399
80 8000 8099
91 9100 9199
In SQL the query reads like:
SELECT company.id, company.name, company.status, address.street,
address.city
FROM company
INNER JOIN address ON company.id=address.company
WHERE address.zip-code_digits BETWEEN zipcode.min AND zipcode.max
ORDER BY company.status, company.name;
The problem is I have no idea how the build the form in which the user
selects a zip-code region, e.g. 73 then retrieve the min (7300) and
max (7399) from the zipcoderegions table and insert them in the
query.
I hope one of you can point me in the right direction to get this
working.
Kind regards,
Annet
