There is a new feature in trunk with needs help testing. The syntax is not yet finalized and may change. I allows to make some form fields conditional on the values of other fields. To use it you must get web2py trunk and clone welcome. To use in legacy apps you must still upgrade and replace your static/js/web2py.js with the one in welcome.
Here are 3 examples: def index(): """ shows bb only if aa is checked """ db.define_table('thing', Field('aa','boolean'),Field('bb')) db.thing.bb.show_if = db.thing.aa==True form = SQLFORM(db.thing) return locals() def index(): """ shows bb only when aa is not set to "x" """ db.define_table('thing', Field('aa','boolean'),Field('bb')) db.thing.aa.requires=IS_IN_SET(('x','y','z')) db.thing.bb.show_if = db.thing.aa!='x' form = SQLFORM(db.thing) return locals() def index(): """ shows bb only when one types "x" or "y" in aa""" db.define_table('thing', Field('aa','boolean'),Field('bb')) db.thing.bb.show_if = db.thing.aa.belongs(('x','y')) db.thing.bb.show_if = db.thing.aa==True form = SQLFORM(db.thing) return locals() show_if is a DAL expression wich is converted to jQuery code and embedded in the form. Not all expressions are supported only ==, !=, contains, and belongs. No logical expressions (&, |). We could add them but I personally believe we should keep this simple. -- --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
