Hi Massimo,
I hope this helps.
Example 1 :
form = SQLFORM.factory(
Field('fromyr', requires=[IS_INT_IN_RANGE
(1950,2000,error_message='Allowed Years, 1950-2000')],label='*
Enrolled - From Year'),
Field('toyr', requires=[IS_INT_IN_RANGE
(1950,2000,error_message='Allowed Years,
1950-2000')],label='* ..................... - To Year'))
In Example 1 when form is submitted and there is an error in the range
the form displays the error below the field and the data inputted is
also displayed back.
-----------------------------------------------------------------------
Example 2
if request.vars.fromyr > request.vars.toyr:
response.flash=T('To year is less than From Year')
return dict(form=form)
In Example 2, when the same form is submitted and the range has no
error but encountered an error during the validation in Example 2 a
blank form is displayed together with the error on the upper portion
of the form (like Welcome to Web2py).
What I would like to have is to display the error "To year is less
than From Year" below the field "toyr" even if I validate the 'toyr'
variable like in Example 2.
Thanks again Massimo.
