I was caught up in excitement upon discovering pow. After setting it up, and testing it out on the project I’m working on now, I encountered a problem. My app is setup to send email using Gmail thru SMTP configured in a Rails environment config, and the email is sent using ActionMailer.
The config looks like this
1 2 3 4 5
The emails were arriving when I tested the app by running
rails server but on the local pow server, authentication errors were the norm. Clearly the environment variables weren’t being set. So I googled pow’s documentation for how to setup environment variables, ending up on this page. While reading through the linked section, I missed something critical.
“Pow attempts to execute two scripts — first .powrc, then .powenv — in the application’s root. Any environment variables exported from these scripts are passed along to Rack.”
So I idiotically set about creating a .powrc file in my user/bin directory. Obviously this did not work, but I wasted an hour or so tweaking random settings trying to get this to work. Then I re-read the page, set about to fix the problem, which I did as follows.
touch .powrcin my project’s root.
- Edit .powrc and add the environment variables as follows:
export GMAIL_USERNAME=username export GMAIL_PASSWORD="my password"
- Restart pow’s worker for the app by running
And that worked!
