问题
I am re-writing my website and am trying to import my members from array of JSON objects.
Each object represents a band that the user has uploaded. So I wrote a quick file that works with the list and my new database / authentication system, auth0.
As outline in the comments below... First I Request an access token so I can create an account for each member using Auth0. Then I iterate through my array of objects representing bands. For each band object I have the code do a few things... First, it creates a new account on my auth system. This sends back a user ID. I add the user ID to the band object to be stored in my database. It adds the location as well as adds a few posts that the user may have had from the old system.
This all works well if I do one user... But if I let it iterate through the whole array it doesn't work. It added about 15 bands to the auth system and 50 bands to the database... It seems like its going too fast to successfully publish them all. Any ideas on how to fix this?
** Also tried this with a for loop instead of for each. Moving everything inside the for loop creates both the same number of bands and user accounts, but now it times out at about 10 bands instead of doing all of them.
Thanks!
