How does on run a script to Populate the datastore via GAE?

[John]

Hello,

When I work with a relation database, I often want to populate the
database before running my web app. So, I'll run some script to
populate the database. This is separate from the web app.

With the GAE, I wrote a class based on db.Model. The Populate()
method stores the data. In the dev environment, I just added this to
my main handler and commented it out on subsequent runs. Lame. How do
i do this right? Is there some way to have dev_appserver.py run the
populate script on demand instead of the webapp?

Thanks for your time and consideration.

Sincerely,

John

Have you looked at bulkloader????

So there is Bulkloader, which lets you convert CSV data into entities,
and inserts them into the datastore:
http://code.google.com/appengine/articles/bulkload.html

However, I found this to be easier to do:
1. Just like in the Bulkloader tutorial, insert this into app.yaml:
- url: /load
script: loader.py
login: admin

2. Now write loader.py so that it would create your initial/test data
and put()'s them into the datastore.

Hello Mahmoud,

Thinking of the entry point as a python handler did the trick for me.

Thanks,
