I'm not feeling well today, so I have to cancel lab today.
Due to the inconvenience, I'm going to remove the deadline from the lab. You still need to complete it (since it is the first part of completing your last project), and I recommend you still try to complete it before Sunday. But if you can't figure out how to do it for whatever reason, then you won't be penalized in your grade.
Also, I'm providing some additional starter code for part 2 of the lab. In particular, you can use the following root route (inside project.py)
@app.route('/')
def root():
# connect to the database
con = sqlite3.connect(args.db_file)
# construct messages,
# which is a list of dictionaries,
# where each dictionary contains the information about a message
messages = []
sql = """
SELECT sender_id,message
FROM messages
ORDER BY created_at DESC;
"""
cur_messages = con.cursor()
cur_messages.execute(sql)
for row_messages in cur_messages.fetchall():
# convert sender_id into a username
sql=
"""
SELECT username
FROM users
WEREE id="""+str(row_messages[0])+""";
"""
cur_users = con.cursor()
cur_users.execute(sql)
for row_users in cur_users.fetchall():
pass
# build the message dictionary
messages.append({
'message': row_messages[1],
'username': row_users[0],
})
# render the jinja2 template and pass the result to firefox
return render_template('root.html', messages=messages)

:You just have to make some minor adjustments to the code above to extract a bit more information from SQL database in order to complete the lab.
