Given the field definition:
Field('company_name', 'reference company', notnull=True)
and the fact that the db.company table has a "format" attribute, you will
get a default "represent" attribute for the db.project.company_name field
that displays the company name rather than its record ID. However, the
represent attribute is used only in SQLTABLE, SQLFORM.grid, and read-only
SQLFORM fields, not anywhere you happen to display the value of the field.
So, you have to be explicit:
{{# Explicitly pass the value to the field's "represent" function.}}
{{=db.project.company_name.represent(item[3])}}
or
{{# Query the db.company table for the item[3] record and extract the
company_name field.}}
{{=db.company(item[3]).company_name}}
In trunk, there is also now a new method that would work if you had a Rows
object instead of using executesql:
def_index:
items = db().select(db.project.company_name)
return locals()
{{for item in items.render():}}
{{=item.company_name}}
{{pass}}
items.render() returns an iterable that generates a copy of each Row object
with each field transformed by its "represent" attribute. You can also
extract just a specific Row:
items.render(0)
As an aside, it would be more common to name the db.project.company_name
field either just db.project.company or db.project.company_id. It is
misleading to name it db.project.company_name, as it doesn't actually store
the name (it is merely represented by the name in some display contexts).
Finally, any reason for using executesql rather than a DAL select?
