Bulk Upload Data to App Engine Dev DB

NOTE: these instructions are for the previous version of App Engine!

How to upload bulk data to App Engine Dev:

1. Create a loader file:

import datetime
import main
from google.appengine.ext import db
from google.appengine.tools import bulkloader

class ClothesLoader(bulkloader.Loader):
def __init__(self):
  bulkloader.Loader.__init__(self, 'Clothes',
                [('title', lambda x: x.decode('utf-8')),
                ('image', lambda x: x.decode('utf-8')),
                ('type', lambda x: x.decode('utf-8')),
                ('tag', lambda x: x.decode('utf-8'))
                ])

loaders = [ClothesLoader]

2. Create a CSV file with your data. Example:

 Jeans, http://localhost:8080/images/jeans1.jpg, bottom, spring

3. In your app.yaml file, MAKE SURE you have the following lines:

 handlers:
- url: /remote_api
 script: $PYTHON_LIB/google/appengine/ext/remote_api/handler.py

4. Also make sure that your PYTHONPATH env var has the directory in which you saved your models. On a Mac:

 export PYTHONPATH=$PYTHONPATH:<directory>

5. Finally, run the following command:

 appcfg.py upload_data --config_file=<loader python file> --filename=<csv data file> --kind=<model name> --url=http://localhost:8083/remote_api <app directory>
