I started to learn Ruby on Rails and I am facing a problem with command logs.
I am starting my server with Command Prompt.
My Ruby version is: 2.7
My Rails version is: 7.0
I want to turn off or hide unnecessary logs.
Logs example:
Post Load (0.5ms) SELECT "posts".* FROM "posts" WHERE "posts"."author_id" = $1 ORDER BY "posts"."created_at" DESC LIMIT $2 [["author_id", 3], ["LIMIT", 3]]
Could not log "sql.active_record" event. Encoding::CompatibilityError: incompatible encoding regexp match (ASCII-8BIT regexp with UTF-8 string) [

I tried to find solution online, but I didn't find anything that will help me.
In my application I need to show a QRCode that embeds a URL to be opened in a browser.
I'm using the Nayuki library in my Qt/C++ application and I encode this string:
"http://mydevice.local"
but my device (Android) decodes it as a literal string, asking me if I want to copy the text.
Encoding a commercial website, say:
"http://www.google.com"
instead works as expected, asking me if I want to open the URL in a browser.
Because the protocol is not enough to trigger this feature, how I need to encode such a URL?
If http://www.google.com works, but http://mydevice.local doesn't, then it's probably not an encoding problem. Maybe the library that decodes qr codes on your device simply doesn't recognize .local as a valid TLD.
I don't have an android device on hand, but an iphone running IOS 15.1 opens a browser with the desired url for both urls.
for reference, here are the qr codes I used (generated using qrencode -t ansiutf8):
http://mydevice.local:

I'm trying to use a redirect_to in my controller and I'm getting an error complaining that redirect_to is not defined (please see logs below)

class ChargesController < ApplicationController

In my rails routes.rb I have

After a resent deploy of a Railsapplication to a Ubuntu 16.04.1 x64 VPS the server is not able to start. Since yesterday I've been trying to solve why, but without any luck. Now I'm totally helpless and out of options.
The deploy stops at:
deploy:migrating
01 $HOME/.rbenv/bin/rbenv exec bundle exec rake db:migrate
01 rake aborted!
01 PG::ConnectionBad: could not connect to server: Connection refused
01 Is the server running on host "127.0.0.1" and accepting
01 TCP/IP connections on port 5432?
Because of this error messages I've changed the settings in the pg_hba.conf and the postgresql.conf to the following examples according to this article http://www.railszilla.com/postgresql-tcpip-connections-port-5432/coffee-break
`pg_hba.conf`
# Database administrative login by Unix domain socket
local all postgres peer
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all md5
# IPv4 local connections:
host all all 0.0.0.0/0 trust
# IPv6 local connections:
host all all ::1/128 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres peer
#host replication postgres 127.0.0.1/32 md5
#host replication postgres ::1/128 md5
And the postgresql.conf settings (See below).
# - Connection Settings -
listen_addresses = '*' # what IP address(es) to listen on;
# comma-separated list of addresses;
# defaults to 'localhost'; use '*' for all
# (change requires restart)
port = 5432 # (change requires restart)
max_connections = 100 # (change requires restart)
#superuser_reserved_connections = 3 # (change requires restart)
unix_socket_directories = '/var/run/postgresql' # comma-separated list of
directories
# (change requires restart)
#unix_socket_group = '' # (change requires restart)
#unix_socket_permissions = 0777 # begin with 0 to use octal notation
# (change requires restart)
#bonjour = off # advertise server via Bonjour
# (change requires restart)
#bonjour_name = '' # defaults to the computer name
# (change requires restart)
# - Security and Authentication -
And after restarting by sudo service postgresql restart I still get the same error after deploying again.
Update, database.yml from server
Here is the database.yml from the server.
production:
adapter: postgresql
host: 127.0.0.1
database: databasename
username: username
password: password
encoding: unicode
pool: 5
In the /var/log/nginx/error.log the last line is like this [ 2017-09-27 13:09:13.4321 1530/7fa87d58e700 age/Cor/Con/CheckoutSession.cpp:285 ]: [Client 1-149] Cannot checkout session because a spawning error occurred. The identifier of the error is c620ca8b. Please see earlier logs for details about the error.
As it says I checked out earlier logs. Below is the whole log. It is reffering to a order_notifier.rb witch is supposed to have a bad syntax.
here is the whole log for the error c620ca8b :

def received(order)
#order = order
mail (to: order.email, subject: 'Hlin Reykdal Concept Store')
end
def shipped(order)
#order = order
mail (to: order.email, subject: 'Order Shipped')
end
end
I've restarted both the nginx by sudo service nginx restart and the app by bundle exec passenger-config restart-app but with out a luck, still getting the same error if I deploy again.
I googled all over the web and looked at hundreds of posts here on stack. Nothing seems to work. Now I'm getting really desperate about this. I've had similar problems before after a deploy, but I've always managed to fix it, but this seems to be aout of my league.
UPDATE
It seems like the production log is stuck in 23/5 2017 even after all my restarts and deploys. It seems like it is stuck in an error from the mailer??

May app is up and running again...
I've had this problem on two apps now. Heroku themselves haven't been able to be much help (yet).
I am using:
Rails 3.2.9
Unicorn
Heroku, with a Postgres Dev (free) database and OpenRedis Micro
MongoDB (for storing social network statuses)
Resque
Resque-scheduler
Everything works great when running with my local Postgres and Redis databases.
And here's an example of the the errors in my Heroku log:

2013-01-01T21:17:27+00:00 app[resque_worker.1]: Running before_fork hooks with [(Job{facebook} | FacebookRefresh | ["facebook_key"])]
I've tried so many before_hook and after_hook things in my unicorn's config file, but none of them seem to help.
# What the timeout for killing busy workers is, in seconds
timeout 60
# Whether the app should be pre-loaded
preload_app true
# How many worker processes
worker_processes 3
before_fork do |server, worker|
# Replace with MongoDB or whatever
if defined?(ActiveRecord::Base)
ActiveRecord::Base.connection.disconnect!
Rails.logger.info('Disconnected from ActiveRecord')
end
# If you are using Redis but not Resque, change this
if defined?(Resque)
Resque.redis.quit
Rails.logger.info('Disconnected from Redis')
end
sleep 1
end
after_fork do |server, worker|
if defined?(ActiveRecord::Base)
ActiveRecord::Base.establish_connection
Rails.logger.info('Connected to ActiveRecord')
end
if defined?(Resque)
Resque.redis = ENV['OPENREDIS_URL'] || 'redis://localhost:6379'
Rails.logger.info('Connected to Redis')
end
end
And my Procfile
web: bundle exec unicorn -c lib/unicorn/config.rb -p $PORT
resque_scheduler: env bundle exec rake resque:scheduler
resque_worker: env QUEUE=* bundle exec rake environment resque:work
So one thing I'm wondering is that my resque_worker doesn't use the Unicorn config at all, and since its running on a completely separate Heroku worker, I'm unsure if there's any way it would know about that stuff. The web instnace is just fine, as is the scheduler. Its just the resque_worker that's blowing up on every postgres call.
I'm not making any particularly crazy database calls from the worker. An example on might be:
def queue_users_for_refresh
FacebookAccount.all.each do |x|
Resque.enqueue(FacebookAccountRefresh, x.username)
end
end
And another one later (in the FacebookAccountRefresh) that is:
FacebookAccount.where(:username => user).first
This looks like an error caused by sharing database connections across processes incorrectly. This happens when the Resque worker isn't re-initializing database connections after forking.
Do you have a Resque initializer? It looks like you're missing after_fork directives for Resque workers to match the ones in your Unicorn app server workers.
Add/edit your Resque initializer file (ie: config/initializers/resque.rb):
Resque.after_fork = Proc.new { ActiveRecord::Base.establish_connection }
