I am attempting to patch web2py to allow support for custom errors in custom
forms, so that the widgets to auto magically render the errors when using
custom form.
Desired functionality should behave such as "{{=form.custom.errors.field}}"
and would display "<div id='field__error' class='error'>must contain a
value!</div>"
The below patch provides this functionality, however, when using regular
form, it will not render the error div.
Perhaps there is a less intrusive method? Something that will still work
with just calling {{=form}}
I would think that the new errors DIV would need to be appended to the
components of the SQLFORM?
Could someone with more knowledge of the web2py innerworkings help me with
this?
