In my application a user enters a boolean value, and later the user can modify the value*.* I want to save the original value in another field, and the user shouldn't be able to see or alter the original value.
Based on the stackoverflow <http://stackoverflow.com/questions/16280220/setting-the-default-of-a-database-field-to-the-value-of-another-field-in-web2py> conversation I tried a simple table with two methods db.define_table('mytable', Field('start_number', 'integer', requires=IS_NOT_EMPTY()), Field('n1', 'integer', default=request.post_vars.start_number), Field('n2', 'integer', compute=lambda r: r.start_number) ) Then I used the database administration to insert a value of 5, but *n1 *had a value of zero (instead of 5). While *n2 *started with the value of 5, whenever I modified *start_number*, it also modified *n2*. By the way, I wish I had web2py in 2003 when I started a bigger web application. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
