Problem with your SQLite table!

[OriLev123]

Hi Tim!
The default argument of the column date should be a function, not the function response.
You wrote: "default=func.now()"
But you should write: "default=func.now" (pass the function as an argument…)

Hi, I am having an error while running your final tutorial 5 while signing or login in, it looks like it can't create or identify any database! Can you please take a look, at where is the problem? Thanks in advance.

OperationalError

FROM user
WHERE user.email = ?
LIMIT ? OFFSET ?]
