Delete multiple posts

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

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?

Issue in Tutorial 3 - file views.py line 42

Hallo Tim,

corrected for the code in the file views.py line 42 in the tutorial,

elif current_user.id != post.id: --> elif current_user.id != post.author:

CMIIW.

Comments add to existing posts

When you delete a post, create a new one with the same id as the old post, the comments from the old post show up on the new post.

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…)

Error in Tutorial 2

I am getting this error in tutorial 2 and I am unable to create the database to store the user sign-up info

from flask_sqlalchemy import SQLAlchemy
from .extension import SQLAlchemy
from .model import _QueryProperty
class DefaultMeta(BindMetaMixin, NameMetaMixin, sa.orm.DeclarativeMeta):
AttributeError: module 'sqlalchemy.orm' has no attribute 'DeclarativeMeta'

there should be another base function defined to render base.html

from flask import Blueprint, render_template
from flask_login import login_required, current_user

views = Blueprint("views", name)

@views.route("/")
def base():
return render_template("base.html", name="guest")
@views.route("/home")
def home():
return render_template("home.html", name=current_user.username)

Getting an error while sign up or login, I think its about database problem! please help me!

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.

After testing the finished product I have noticed that when you make more than one post the website says that you do not have permission to delete the second post
