How to obtain the image path/ url from a file uploaded on an openshift data dir to be stored in a postgresql database? - postgresql

Question

I am a self-taught programming newbie here so please bear with me. I am trying to create a site which allows users to upload their images on. With the patience of another user, I was able to get some answers as to how to create and allow users to upload their images onto the data drive on openshift. However, now I need to be able to store the image path or url onto a postgresql database (which can be called on later) so that each user will be able to keep track of the images that they have uploaded. I am currently stymied by this.
Here are the fragments of code which I feel plays a big role in answering this question:
class Todo(db.Model):
__tablename__ = 'todos'
id = db.Column('todo_id', db.Integer, primary_key=True)
title = db.Column(db.String(60))
text = db.Column(db.String)
done = db.Column(db.Boolean)
pub_date = db.Column(db.DateTime)
user_id = db.Column(db.Integer, db.ForeignKey('users.user_id'))
image_url = db.Column(db.String)
def __init__(self, title, text, image_url):
self.title = title
self.text = text
self.image_url = image_url
self.done = False
self.pub_date = datetime.utcnow()
def allowed_file(filename):
return '.' in filename and \
filename.rsplit('.', 1)[1] in app.config['ALLOWED_EXTENSIONS']
#app.route('/upload', methods=['POST'])
def upload():
# Get the name of the uploaded file
file = request.files['file']
# Check if the file is one of the allowed types/extensions
if file and allowed_file(file.filename):
# Make the filename safe, remove unsupported chars
filename = secure_filename(file.filename)
# Move the file form the temporal folder to
# the upload folder we setup
file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
# Redirect the user to the uploaded_file route, which
# will basicaly show on the browser the uploaded file
return redirect(url_for('uploaded_file',
filename=filename))
#app.route('/uploads/<filename>')
def uploaded_file(filename):
return send_from_directory(app.config['UPLOAD_FOLDER'],
filename)
#app.route('/new', methods=['GET', 'POST'])
#login_required
def new():
if request.method == 'POST':
if not request.form['title']:
flash('Title is required', 'error')
elif not request.form['text']:
flash('Text is required', 'error')
else:
todo = Todo(request.form['title'], request.form['text'])
todo.user = g.user
db.session.add(todo)
db.session.commit()
flash('Todo item was successfully created')
return redirect(url_for('index'))
return render_template('new.html')
The current code that I have is pieced together by various tutorials and examples.
Currently, I am trying to merge the "Todo" db, "upload" function and "new" function and am having very little success. Using the little knowledge I have, I have merely added the "image_url" portions in which will be a column that is intended to house the image path. I would greatly appreciate it if somebody could shed some light on this conundrum. Thanks a million.
Respectfully,
