SQLAlchemy DateTime result 0's

[AMarotta97]

Hi all, I am new here and also quite new to python, so I apologize in advance for any errors I may make, just let me know any I will prevent it in the future, thank you.

So My current function is using flask, having a form to book an appointment, so far in my template for the time part is:

<form  action="/patient/patientbook" method="POST" role="form">
  <label for="name">Start Time:</label>
   <input type="datetime-local" class="form-control" id="starttime" name="starttime" required>
<br>
</form>

And inside my python script:

# Databse model for a Booking
class Book(db.Model):
    __tablename__ = 'booking'
    bid = db.Column(db.Integer, primary_key=True)
    starttime = db.Column(db.DateTime(), nullable=False)

    count = 1

    def __init__(self, starttime):
        self.starttime = Book.starttime
        Book.count += 1

class BookSchema(ma.Schema):
    class Meta:
        # Fields to expose
        fields = ('bid', 'starttime')

book_schema = BookSchema()
books_schema = BookSchema(many=True)

# Route for a patient to make a booking
@app.route("/patient/patientbook", methods=["POST", "GET"])
def patientBook():
    if request.method == 'POST':
        pemail = (request.form.get('email'))
        pname = (request.form.get('pname'))
        starttime = request.form['starttime']
        print(starttime)
        starttime = "{}:00".format(starttime)
        print(starttime)

        if pemail and pname and starttime:
            new_booking = Patient(pemail, pname)
            new_bookingtwo = Book(starttime)
            db.session.add(new_booking)
            db.session.add(new_bookingtwo)
            db.session.commit()

    return render_template('patient/patientbook.html')

And After I have completed the process and view the results in the database (google cloud db),
I receive the following:

Output:
MySQL [crud]> select * from booking;
+-----+---------------------+
| bid | starttime           |
+-----+---------------------+
|   1 | 0000-00-00 00:00:00 |
|   2 | 0000-00-00 00:00:00 |
|   3 | 0000-00-00 00:00:00 |
+-----+---------------------+
3 rows in set (0.11 sec)

Any help appreciated!

Also another thing, I am working on linking up my database so that a Doctor will be linked with an appointment time with a patients email, any guide on how to do that would also be appreciated,
Thank you!!!
