How to format a datetime MySQL database field to local using strftime()

[nikos]

I decided to move from 'pymysql' to 'bottle-pymysql' plugin. i have this code:

# dbhost is optional, default is localhost
plugin = bottle_pymysql.Plugin( dbuser='nikos', dbpass='*******', dbname='counters', charset = 'utf8' )
app.install(plugin)

.....
.....

for visit in visits:
		visit = visit.strftime('%A %e %b,  %I:%M %p')

When trying to read that view, bottle() gives me this error:

Output:
Traceback:
Traceback (most recent call last):
  File "/usr/lib64/python3.6/site-packages/bottle.py", line 862, in _handle
    return route.call(**args)
  File "/usr/lib64/python3.6/site-packages/bottle.py", line 1740, in wrapper
    rv = callback(*a, **ka)
  File "/usr/lib/python3.6/site-packages/bottle_pymysql.py", line 174, in wrapper
    rv = callback(*args, **kwargs)
  File "/home/nikos/wsgi/www.py", line 132, in log
    visit = visit.strftime('%A %e %b,  %I:%M %p')
AttributeError: 'str' object has no attribute 'strftime'

What does this error mean?

I don'understand it, because before using bottle_pymysql i uses pymysql adn that line was interpreted correctly. Now with bottle_pymysql it does not. What can i do?
Thank you.
