Re: [web2py] Re: REF: DAL Catching errors
Good point. web2py normally does a rollback if a request results in an exception, but if you catch the exception, you would need to do the rollback yourself to prevent web2py from committing the transaction at the end of the request.

Re: [web2py] Re: REF: DAL Catching errors
It depends on how the particular exception class is implemented. In general, if you do str(error), you get the error message. I think in most exception classes, error.args[0] is also typically the error message. This is a general Python issue and not specific to web2py. try: except db._adapter.driver.IntegrityError as e: return str(e) Anthony On Saturday, January 11, 2014 1:55:30 AM UTC-5, software.ted wrote: > > Hi Anthony! > > Those gems we need to know!!!, since i have to extract undocumented > details on this list, I would like to find out how i can then get system > generated messages cause there are many integrity error > descriptions...instead of me having one message like this: > > try: > ... > except db._adapter.driver.IntegrityError: > err_msg = "Duplicate record in database" > > I would like to have a situation were i can get system messages of the > specific integrity error enountered: > > try: > ... > except db._adapter.driver.IntegrityError: > err_msg = db.[some object].errorMessage > > > Any pointers? > > > On Sat, Jan 11, 2014 at 8:11 AM, Anthony >wrote: > >> Another one of our great undocumented gems. :-) >> >> -- >> 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. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to web2py+un...@googlegroups.com . >> For more options, visit https://groups.google.com/groups/opt_out. >> > > > > -- > > ... > Teddy Lubasi Nyambe > Opensource Zambia > Lusaka, ZAMBIA > > Cell: +260 97 7760473 > website: http://www.opensource.org.zm > > ~/ > Human Knowledge belongs to the world! - AntiTrust > > Man is a tool-using animal.

Re: [web2py] Re: REF: DAL Catching errors
IntegrityError is defined by the database driver, so needs to be imported. Actually, I forgot, we made this easier, so it is not adapter-dependent -- you can do: try: ... except db._adapter.driver.IntegrityError: ... Another option is: def insert_error_handler(table, fields, error): [handle the error] db.mytable._on_insert_error = insert_error_handler There is also an _on_update_error callback.
