I have a field that references another table
Field('material', db.material)
I can get SQLFORM to give me a drop down list of available material
names
Field('material', db.material,
requires=IS_IN_DB(db,'material.id','material.name'))
I can get SQLFORM to insist on filling the field
Field('material', db.material,
requires=IS_NOT_EMPTY())
I would like to get both at once. However
Field('material', db.material,
requires=[IS_IN_DB(db,'material.id','material.name'),IS_NOT_EMPTY()])
does not show the drop down list.
The problem seems to be in placing IS_IN_DB inside a list,
because this does not work
Field('material', db.material,
requires=[IS_IN_DB(db,'material.id','material.name')])
