Hello!!

Please, i have a field that i dont want to be an empty string.

I tried those choices:

1/ if ' ' in project:

My_error_Msg2 =  'Please your project can not be empty' raise osv.except_osv(_("Error!"), _(My_error_Msg2))

----> when the field contain two string separated by a space it raises an exception

2/ if  project == ' ':

My_error_Msg2 =  'Please your project can not be empty' raise osv.except_osv(_("Error!"), _(My_error_Msg2))

----> it doesnt raise an exception

Please help
