Rails assets:precompile tries to connect to DB

Question

Rails assets:precompile tries to connect to DB

sabudaye opened this issue 9 years ago · comments

I'm trying to deploy my application with maily_herald gem to Heroku, and it fails with this reason:

could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port xxxx?

I reproduced this on local machine

RAILS_ENV=production rake assets:precompile
and got this error:

RAILS_ENV=production rake assets:precompile --trace
** Invoke assets:precompile (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)
** Execute environment
rake aborted!

@sabudaye You have to add a package to your Heroku setup such as https://postgres.heroku.com or similar for other DB types.

Sebastian Velandia · Answer 2 · Mon Oct 19 2015 07:25:51 GMT+0800 (China Standard Time)

lol it is because you do not have any database yet set up.

In local you have to create the db, run these commands

rake db:drop db:create db:migrate

with that your local database will be recreated, but in your heroku instance if you have a database addon installed you won't have to run those commands manually. Also make sure you run maily_herald migrations!

@Phitherek, @ssoulless thank you, but i'm already added DB on Heroku and also have db setup on local machine. This issue is not about my db configuration, is about https://devcenter.heroku.com/articles/rails-asset-pipeline#troubleshooting
I runned asset:precompile task on nonexisting database just for reproducing error:

If rake assets:precompile is still not working, you can debug this locally by configuring a nonexistent database in your local config/database.yml and attempting to run rake assets:precompile. Ideally you should be able to run this command without connecting to the database.

rails asset:precompile task should not require connection to database, and without maily_herald gem it works fine.

I found same issues in other gems:
thiagopradi/octopus#287
spree/spree#3688
mbleigh/acts-as-taggable-on#396

You also could use the activerecord-nulldb-adapter gem -> https://github.com/nulldb/nulldb
