Python Flask with SQLAlchemy Basics Connecting to a Database with SQLAlchemy Working with a Plant Database

[Solved] My solution works locally but isn't accepted

My app.py file looks like this:

from models import db, Plant, app
from flask import render_template, url_for, request, redirect


@app.route('/')
def index():
    return render_template('index.html')


@app.route('/form', methods=['GET', 'POST'])
def form():
    if request.form:
        new_plant = Plant(
            plant_type=request.form["type"],
            plant_status=request.form["status"]
        )
        db.session.add(new_plant)
        db.session.commit()
        return redirect(url_for('index'))
    return render_template('form.html')


if __name__ == '__main__':
    app.run(host='0.0.0.0', port=8000)

I've set up this project locally and it runs perfect, but the quiz won't accept my answer. The feedback I get is to use db.add(). But in the previous video we learned to use db.session.add(). Switching to db.add() instead of db.session.add() also doesn't work.

Also: There's a typo in the form.html file. Line 4:

<form action="{{ url_form('form') }}" method="POST">

should be:

<form action="{{ url_for('form') }}" method="POST">

Switching to db.add will work, but you also need to accommodate a specific formatting quirk of the challenge. It apparently wants you to place the closing parenthesis for Plant on the same line as the 2nd argument, like this:

        new_plant = Plant(
            plant_type=request.form["type"],
            plant_status=request.form["status"] )   # <-- note closing parenthesis
        db.add(new_plant)
        db.commit()

Your formatting is technically fine and looks much nicer as well! :+1:

You may want to report this, along with the typo you found, directly to the Support team. It should get you the "special Exterminator badge". :beetle:

Thanks Steven! Your code works. I'll report the issue to Treehouse
