Flask+Cloudinary upload error on pythonanywhere

Question

Hi everebody!

Please help me, I'm stuck with cloudinary uploader error. The problem is that on localhost this function works well, but after deploying on pythonanywhere server it doesn't. Use:

• • Python3.4
    • sqlite database
      • SQL Alchemy 1.1.4
    • Flask 0.11.1
    • cloudinary python module
    • flask-googlemaps module
    • httplib2 module
    • requests module

Bits of my Code:

from flask import Flask, render_template, request, redirect, url_for, \
    flash, jsonify, make_response
from flask import session as login_session  # to avoid confusion with DB session
import random
import string
import httplib2
import json
import requests
import content
# Cloudinary API imports

import cloudinary
import cloudinary.uploader
from cloudinary.uploader import upload
import cloudinary.api
from cloudinary.utils import cloudinary_url


CLOUDINARY = {
  'cloud_name': 'ainsolence',
  'api_key': 'xxxxxxxxxxxxxxxxxxx',
  'api_secret': 'xxxxxxxxxxxxxxxxxxxxxxx',
}

cloudinary.config(cloud_name='ainsolence', api_key='xxxxxxxxxxxxxxxxxxxx',
                  api_secret='xxxxxxxxxxxxxxxxxxxxxxx')

...

# Create route for editCategory function

# Create route for uploadCategoryImage function

@app.route('/catalog/<int:category_id>/edit/upload/', methods=['GET',
           'POST'])
def uploadCategoryImage(category_id):
    if 'username' not in login_session or login_session['email'] \
        not in ADMIN:
        return redirect('/login')
    catalog = session.query(Category).all()
    categoryToEdit = \
        session.query(Category).filter_by(id=category_id).one()
    upload_result = None
    image_url = None
    if request.method == 'POST':
        file = request.files['file']
        if file:
            try:
                upload_result = upload(file, use_filename='true',
                                       folder='Menin_zherim/Categories')
                print ('This is upload result ' + upload_result)
                (image_url, options) = \
                    cloudinary_url(upload_result['public_id'], format='jpg')
                print ('Image url = ' + image_url)
                categoryToEdit.image_url = image_url
                session.add(categoryToEdit)
                session.commit()
                flash('Image for category successfully uploaded!')
                return redirect(url_for('editCategory',
                                category_id=category_id, catalog=catalog,
                                title='Edit category'))
            except:
                flash('Error in uploading', )
                return redirect(url_for('editCategory',
                                category_id=category_id, catalog=catalog,
                                title='Edit category'))
    else:
        return render_template('uploadCategoryImage.html',
                               category_id=category_id,
                               catalog=catalog,
                               category=categoryToEdit,
                               title='Upload image category')

#In uwsgi file I put this:
#Cloudinary base url
os.environ["CLOUDINARY_URL"] = "CLOUDINARY_URL=cloudinary://blablablabla:XXXXXXXXXXXXXXXXXXXX@ainsolence"

PS: of course I use real api_key and api_secret in my code

Please help me, if you have any advices where I can find the answer or just how I can understand this issue

Thank you Best Regards Anton

If you're doing this from a free PythonAnywhere account, then you haven't configured the cloudinary library you're using to use the PythonAnywhere proxy for outgoing connections. The proxy details are proxy.server:3128.
