Where to find Alert/Flash messages

[Brennie Standy]

I have a ticket where our client wishes to see a list of all flash/alert/error messages, including anything from "Logged in" to our own customized error messages set by the previous developer. Where in the app can I find this list? Standard global search is not proving useful. Thanks!

You can see error tickets from the Admin module (screenshot below). I believe they are stored on the filesystem, not in a table. I have never looked.

Re Flash messages, unless they are generated from error tickets, i doubt they are stored anywhere.

I have a function that logs errors (and anything else I want) in an EventLog table. You are probably catching all errors and trying to handle them gracefully so its not hard to grab the error that was raised at that point. Trying to extract the error from the exception took me a little looking for. My code for that is below. 

Also, there is a logging feature in web2py. http://web2py.com/books/default/chapter/29/04/the-core?search=logger#Logging 

Maybe something there helps?

def MyFunction:
try:
#My code

    except Exception as e:
        Result = Public.LogError(pyFileName, e, I, ReturnJson = False)


Public Module
-------------
from datetime import datetime
import inspect
import sys
import simplejson as json

def LogError(FileName, e=None, ExtraInfo = "", LogType = 'Error', ReturnJson=False, FlashError = False):

    NOW = datetime.now()
    curframe = inspect.currentframe()
    ErrFunction = inspect.getouterframes(curframe, 2)
    Msg = sys.exc_info()[0]
    LogFunction = "%s < %s < %s [%s]" %(ErrFunction[1].function, ErrFunction[2].function, ErrFunction[3].function, FileName)

    if e:
        if hasattr(e, 'message'):
            Msg = "%s [Sys: %s]" % (e.message, Msg)
            #print(e.message)
        else:
            #print(e)
            Msg = "%s [Sys: %s]" % (e, Msg)

    if not Msg: Msg=''
   
    print('------------------------------- ERROR -----------------------------------')
    print("%s: FUNC: %s. ERR: %s. %s" % (str(NOW)[11:19], LogFunction, Msg, ExtraInfo))
    Common.AddLogEntry(LogType=LogType, LogFunction = LogFunction, LogMessage = '%s %s' % (Msg, ExtraInfo))
   
    print('-------------------------------------------------------------------------')
   
    result = ("%s: FUNC: %s. ERR: %s. %s" % (str(NOW)[11:19], LogFunction, Msg, ExtraInfo))

    message = result
    if 'ERR: UNIQUE constraint failed' in message:
        startat = message.find("ERR: UNIQUE")
        char1 = ":"
        char2 = "["
        table_info = message[message.find(char1,startat) + 1: message.find(char2,startat)]
        message = f'There is already a record in the database just like this one. We cannot add another. ({table_info})'

    if FlashError: current.response.flash = XML("Error: " + message + current.response.flash)

    result = dict(Success = False, Message = message)
    if ReturnJson:
        result = json.dumps(result)
   
    logger = logging.getLogger("web2py.app.myapp")
    logger.setLevel(logging.DEBUG)
    logger.error(message)

    return result
