Seeding in Production at Heroku

Locally, my seeding works fine running this script from my package.json file

“seed1”: “adonis seed --force --files UserSeeder.js”

However, I get the following error when trying to run this script below for production.
“heroku-postbuild”: “npm run production && npm run seed1”

Error: ENOENT: no such file or directory, open '/tmp/build_e21559bb4d5a80d45f8cf95569fd3e11/.env'

I have also tried to change the script to

“node ace seed --force --files UserSeeder.js”

but I get the same error

I ended up creating a migration and putting the logic inside the up() method. Worked fine.

I’m not sure if this is ok or not though.

If you look at the error message it’s telling you it cannot find the .env file.

I doubt you’d want it to work in a postbuild script anyway, as that would rerun the seeder every deploy… seeding really only ought to happen once, right at the start of a project, for initial data.

Presumably you could also, manually, post-deploy simply do something like:
heroku run node ace seed --force

Haven’t used heroku in ages… but this seems accurate :slight_smile:


I’m having the same problem trying to run ace commands on Heroku but the error message is:
Error: ENOENT: no such file or directory, open '/app/.env'
…which seems weird since this file does not exist for local dev either.

Any pointers?

Set your env variables when you run the script
ENV_SILENT=true FOO=bar node ace seed
ENV_SILENT disables .env file loading and then you can pass in all other env variables required for given command
