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.

no logout.html file in templates folder (tutorial3)

In turtorial3 file, here is no logout.html file in the templates file but there is a reference "href="/logout" in base.html in line 30

I don't know if I am right or completely wrong about this.

If I am wrong, sorry for your waste of time

i am getting an error the for tutorial 1

I am getting the following error when runing the create_function function:

Traceback (most recent call last): File "c:\Users\aalba\OneDrive\Documents\techwithtim_Flask\app.py", line 1, in <module> from website import create_app ImportError: cannot import name 'create_app' from 'website' (c:\Users\aalba\OneDrive\Documents\techwithtim_Flask\website\__init__.py)

I believe it is something silly. The code is exactly the same could it be something with the path variable or venv?

Problem with your SQLite table!

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…)

No home.html file

The home.html file is not updated past video tutorial #1. I tried to view the code in the home.html file for Tutorial #3 but it has the code for Tutorial #1 in all of the versions.

Delete multiple posts

It is not possible to delete all posts when there are multiple posts created by one user.
