Question

Why is letter_opener not working?

Posted March 26, 2019 1.5k views
Ruby on RailsUbuntu 18.04

Hello,

I’m just starting with a DO droplet, using Ubuntu 18.04, where I installed my Rails app as environment = “development” .
In my local machine I set the gem “letter_opener”, to access and debug the emails that has to be sent, and the same configuration is on the droplet (with specific hosts, of course).
But for some reason, the emails doesn’t seem to be sent, also I can’t see them in the browser… Anyone would have had the same issue? Did I miss something in my configuration?
Thx in advance for your help!

Apparently I’m not the only one having this issue… It seems that the best option would be to dockerize the application, switching from letter_opener to mailcatcher gem^^

Greetings!

It can be difficult to say what is different between the staging and production environments here, it could be the most seemingly insignificant thing that just happens to impact your use case in the right way. I welcome anyone with more experience with letter_opener to weigh in, but I wanted to also do my best to find an answer for you. I found a GitHub issue that seems a bit dated, but had a lot of advice which may be helpful:

If you do find the answer there, I hope you will comment back so that it helps someone else later :)

    Hello, and thank you for your answer! I looked at this Github issue, and I guess my best option now would be to get the logs from my application, to help defining the exact problem… But can’t find how to access… In local environment the bin/rails s command that starts the server also provides logs, but on DO droplets, Rails is setted as a service, so how could I access those logs? Thx in advance!
