While I’ve been busy finishing my Google App Engine solution during the last several months, I now find Google has me painted me into a corner due to changes and differences between the local dev_server and appspot.
The scenario: My app is deployed on appspot with Federated OpenID authentication.
The problem: Google does not support data uploads while apps are configured to use OpenID. (They are aware of this problem and do not consider it a bug.)
Several years ago Nick Johnson posted a remote_api and OpenID workaround on his blog, but several people report it no longer works.
In addition, the latest (2nd) edition of Dan Sanderson’s book “Programming Google App Engine” no longer contains a chapter on data uploads. There is a chapter on Backup and Restore, but I can not restore data until I back it up, and I can not back it up until the data exists!
I can not believe I’m the only one in this predicament — it seems it should be a very common need — I simply need to upload data while my app uses OpenID.
Keep in mind that everything about my local dev_server Python app works great (appcfg.py, upload_data, remote_api, CSV yaml configs, etc.), but this problem on appspot prevents me from releasing my app!
Does anyone have a simple, up-to-date, and documented recipe to upload thousands of records to app engine? Custom upload handler endpoint? Bundle the data file(s) with new app verions, then read them somehow? Post CSV files to Google Drive and read them from a task queue?
Any ideas?
You can try this as a work around:
