I restart local database (postgres in a docker container) and then my server bundle exec bin/rails s
After that I go to the console with bundle exec bin/rails c
(or bin/rails c
or bundle exec rails c
),
being in the project root folder.
Sometimes (not sure exactly why yet), environment get messed up.
When trying a request such as : User.count
I get a weird error.
could not connect to server: No such file or directory (ActiveRecord::ConnectionNotEstablished)
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
While the server is running locally and could connect to the database.
It happens the console explicitly starts with the following announcement :
Running via Spring preloader in process 1720240
Hey ! That's a good hint.
Of course, I did disregard it completly for a couple hours more than once.
The solution is so often related though. You reload the database and the server,
under spring preloader's feet.
spring prelaoder is so lost ! Let's restart it too.
Solution :
spring stop
bin/rails console
and voilà ! It works again.
