PG::ConnectionBad (fe_sendauth: no password supplied )
You may need to create a new PSQL user. Follow this guide to define a username and password.
To keep this information private, list PSQL_USERNAME and PSQL_PASSWORD
under config/env/test.env and config/env/development.env, then add username
and password to config/database.yml:
You may also want to set PSQL_HOST="localhost" in config/env/test.env and config/env/development.env.
FATAL: database files are incompatible with server
DETAIL: The data directory was initialized by PostgreSQL version 9.4, which is
not compatible with this version 9.6.1.
brew install [email protected]brew services start [email protected]- Stop the server by running
brew services stop [email protected].
PG::ConnectionBad (could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
)
rm -rf /usr/local/var/postgres/postmaster.pid
Please note the below was done on Arch Linux, so adjust as neccessary
If the above does not work, try to restart the service. If the service refuses to start, it will most likely output a log using journalctl. View this by running journalctl -xe.
If the log reports that a file exists in /var/postgres/data, delete the file with super permissions.
Recreate the server clusters:
sudo -iu postgres
initdb -D /var/lib/postgres/data
FATAL: database "ifme_test" does not exist
bin/rake db:create db:migrate RAILS_ENV=test
Error during failsafe response: Devise could not find the `Warden::Proxy` instance on your request environment.
21:30:29 web.1 | Make sure that your application is loading Devise and Warden as expected and that the `Warden::Manager` middleware is present in your middleware stack.
21:30:29 web.1 | If you are seeing this on one of your tests, ensure that your tests are either executing the Rails middleware stack or that your tests are using the `Devise::Test::ControllerHelpers` module to inject the `request.env['warden']` object for you.
You need to run Postgres in the background, if you're using macOS or Linux run postgres -D /usr/local/var/postgres
Make sure to start Postgres first to avoid internal server error.
brew services start postgres
bin/rake db:setup db:test:prepare
Sorry, you can't use byebug without Readline. To solve this, you need to
rebuild Ruby with Readline support. If using Ubuntu, try `sudo apt-get
install libreadline-dev` and then reinstall your Ruby.

This is likely due to a lingering Category ID that is stored in a Strategy object. This used to occur when a Category object was destroyed while there was a Strategy object that stored the corresponding Category ID (a recent PR fixed this).
There is a rake task setup to clean your database to eliminate the issue. Simply run bundle exec rake cleaner:remove_lingering_categories.
