I'm having some trouble loading custom configuration data from a yml file. I've looked at a few resources and can't seem to get anywhere with it.
When I try to load some custom settings from the yml file I get an empty hash.
my application.rb contains:
config.myapp = config_for(:myapp)
my myapp.yml contains:
default: &default
emails:
support: test#myapp.com
marketing: marketing#myapp.com
address: 123 Test lane
production:
<<: *default
development:
<<: *default
test:
<<: *default
When I call:
Rails.configuration.myapp
I get:
{}
Any thoughts what the issue might be?
Thanks
It's got something to do with the lifecycle of the Application object and where your config.myapp = config_for(:myapp) call sits.
So I tried it locally and solved this problem by putting it inside a config.before_initialize callback block:
this is in my config/application.rb file
config.before_initialize do
config.myapp = config_for(:myapp)
end
and then in rails console Rails.application.config.myapp correctly dumps the config parsed from yml.

I'm following the 'Running Rails on the Cloud Run environment' instructions and have hit a snag. I used their provided github repo and the google cloud shell and I had success in launching the working application.
Now, I am trying to integrate Cloud Run into my rails template. While 'Deploying the app to Cloud Run' using the cloudbuild.yaml file provided, the build crashes during database migration. I am using postgreSQL. Here are the error details:
The error
"bundle exec rails db:migrate" ->
"ActiveRecord::ConnectionNotEstablished: could not connect to server: No such file or directory"
I think I've traced it to database.yml file where Google recommends this host:
production:
<<: *default
database: <%= ENV["PRODUCTION_DB_NAME"] %>
username: <%= ENV["PRODUCTION_DB_USERNAME"] %>
password: <%= Rails.application.credentials.gcp[:db_password] %>
host: "<%= ENV.fetch("DB_SOCKET_DIR") { '/cloudsql' } %>/<%= ENV["CLOUD_SQL_CONNECTION_NAME"] %>"
It is unclear where this ENV.fetch("DB_SOCKET_DIR") comes from [at least to me, I'm new]. Their git repo holds a folder where I found templates for another build that included an app.standard.yaml and a config/database_unix.yml that I've tried integrating.
app.standard.yaml:
entrypoint: bundle exec rackup --port $PORT
runtime: ruby27
env_variables:
SECRET_KEY_BASE: <SECRET_KEY>
RAILS_ENV: production
INSTANCE_UNIX_SOCKET: /cloudsql/<PROJECT-ID>:<INSTANCE-REGION>:<INSTANCE-NAME>
DB_USER: <YOUR_DB_USER_NAME>
DB_PASS: <YOUR_DB_PASSWORD>
DB_NAME: <YOUR_DB_NAME>
beta_settings:
cloud_sql_instances: <PROJECT-ID>:<INSTANCE-REGION>:<INSTANCE-NAME>
database_unix.yml:
# [START cloud_sql_postgres_activerecord_connect_unix]
unix: &unix
adapter: postgresql
# Configure additional properties here.
# [END cloud_sql_postgres_activerecord_connect_unix]
pool: 5
timeout: 5000
# [START cloud_sql_postgres_activerecord_connect_unix]
# Note: Saving credentials in environment variables is convenient, but not
# secure - consider a more secure solution such as
# Cloud Secret Manager (https://cloud.google.com/secret-manager) to help
# keep secrets safe.
username: <%= ENV["DB_USER"] %> # e.g. "my-database-user"
password: <%= ENV["DB_PASS"] %> # e.g. "my-database-password"
database: <%= ENV.fetch("DB_NAME") { "vote_development" } %>
# Specify the Unix socket path as host
host: "<%= ENV["INSTANCE_UNIX_SOCKET"] %>"
# [END cloud_sql_postgres_activerecord_connect_unix]
development:
<<: *unix
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
<<: *unix
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 1 } %>
database: <%= ENV.fetch("DB_NAME") { "vote_test" } %>
production:
<<: *unix
database: <%= ENV.fetch("DB_NAME") { "vote_production" } %>
Some other solutions I've seen mention this instead of host:
socket: “/cloudsql/project_id:us-central1:photo-album-production”
I tried this with no luck. I cloned the repo to my machine and re-tried the Cloud Run instructions. No success this time as it's getting the same migration error. Am I thinking about this wrong?
Check this out: https://cloud.google.com/sql/docs/postgres/connect-build.
In short, you'll need to run the Cloud SQL Auth Proxy to create a Unix socket in Cloud Build so your app can connect.
If you're using a private IP instance, you'll need to make sure you're using private pools.
I'm trying to send custom metrics to NewRelic insights, but unfortunately it is not working for my Rails app that is currently sending default data to New Relic.
Steps to reproduce
I just logged in the console of the working application and ran the following command:
NewRelic::Agent.record_metric('/Custom/MyCategory/MyMetric', 5)
Unfortunately it never appeared in the Insights Data Explorer.
The configuration in the application is the following:
common: &default_settings
license_key: <MY_KEY>
app_name: my_app
log_level: info
development:
<<: *default_settings
app_name: executive_alerts (development)
monitor_mode: false
test:
<<: *default_settings
app_name: executive_alerts (test)
monitor_mode: false
staging:
<<: *default_settings
app_name: executive_alerts (staging)
production:
<<: *default_settings
Thank you!
From the documentation for the New Relic agent:
http://www.rubydoc.info/github/newrelic/rpm/NewRelic/Agent#record_metric-instance_method
https://github.com/newrelic/rpm/blob/c252fad410a5d41a65a827d633338af609f8dff6/lib/new_relic/agent.rb#L143-L144
metric_name should follow a slash separated path convention. Application specific metrics should begin with Custom/.
Change your command from:
NewRelic::Agent.record_metric('/Custom/MyCategory/MyMetric', 5)
to:
NewRelic::Agent.record_metric('Custom/MyCategory/MyMetric', 5)
SCENARIO:
I have a ruby (2.2.3) on rails (4.2.4) application, working on a Firebird(2.5) database through activerecord-fb-adapter(1.0.2). This is a legacy database with ISO-8859-1 encoding, so I set up my database.yml file with encoding ISO-8859-1. Rails default encode is UTF-8, so I set up my application.rb file like this:
#config\application.rb
config.encoding = "ISO-8859-1"
Database.yml file:
#config\database.yml
default: &default
adapter: fb
encoding: ISO-8859-1
create: false
charset: ISO8859_1
development:
<<: *default
database: db/cadastro.fdb
username: sysdba
password: masterkey
host: localhost
ERROR:
The data coming from the database are ok, but when I tried to save data into the database or tried to show hard coded strings in a browser I receive a character error:
browser error:
code:
<th class="text-center">Data de Serviço</th>
output:
Data de Serviço
database error:
seeds:
MotoboyServiceType.where(:service_type => "REDAÇÃO").first_or_create
database:
REDAÇÃO
QUESTION:
How can I setup my application, so I can save the right data on database and display strings with right special characters?
I am trying to set up ruby on rails to develop locally on a 64 bit windows 7 machine using SQL server 2005. We have an existing database and it does not conform to the ruby way so I created a table to test conectivity.
Unable to find information on properly configuring the database.yml file I suspect my problem is there. I have both 32-bit and 64-bit DSNs defined. When I run the console I get "Table doesn't exist"
Here's my database.yml. I don't know
default: &default
host: 111.222.333.444
adapter: sqlserver
mode: odbc
dsn: DSN_Name
database: ERP
username: sa
password: ********
development:
<<: *default
host: 111.222.333.444
adapter: sqlserver
mode: odbc
dsn: DSN_Name
database: ERP
username: sa
password: ********
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
<<: *default
database: db/test.sqlite3
production:
<<: *default
database: db/production.sqlite3
Does anyone know how the default works? I can't find any information on it. Specifically "<<: *default"
I updated my database.yml file. Created a table for testing; used the plural and ID for the primary key:
CREATE TABLE [dbo].[Cars](
[ID] [int] NULL,
[Name] [nchar](10) COLLATE SQL_Latin1_General_CP1_CI_AS NULL
) ON [PRIMARY]
Created a model
class Car < ActiveRecord::Base
end
But I get "Table doesn't exist" after connecting to Car and entering 'Car'. Anyone have any idea what the next step would be to debug this?
The &default in the line default: &default, means make the key/value pairs under this YAML namespace available as the variable *default.
The <<: *default lines are taking those key/value pairs, and making them part of the other groups, so you only need to change values that are different from the default: group.
If all your databases are on the same machine, then your database.yml should look a lot like this:
default: &default
host: 111.222.333.444
adapter: sqlserver
mode: odbc
dsn: DSN_Name
username: sa
password: ********
development:
<<: *default
database: ERP_development
test:
<<: *default
database: ERP_test
production:
<<: *default
database: ERP_production
Since you are on sqlserver, you'll probably have to create all those databases yourself (instead of letting Rails do it for you).

Force Schema To Lowercase
Although it is not necessary, the Ruby convention is to use lowercase
method names. If your database schema is in upper or mixed case, we
can force all table and column names during the schema reflection
process to be lowercase. Add this to your config/initializers file for
the adapter.
ActiveRecord::ConnectionAdapters::SQLServerAdapter.lowercase_schema_reflection = true
Schemas & Users
Depending on your user and schema setup, it may be needed to use a
table name prefix of dbo.. So something like this in your initializer
file for ActiveRecord or the adapter.
ActiveRecord::Base.table_name_prefix = 'dbo.'
I'm new at ruby on rails, and I've noticed that when I send an email, my site_name and site_url vars are not being recognized from the mailer files.
In my config.yml file I've got the following:
development: &local
site_name: my site name
site_url: http://localhost:8282
company_name: my company name
admin_email: admin#domain.com
support_name: askdjaskd Support
support_email: support#domain.com
production:
<<: *local
staging:
<<: *local
test:
<<: *local
And in the mailers I call them the as follows:
#body[:url] = "http://#{Setting.get(:site_url)}/"
Do I need to write a require statement at the beginning of the mailers? If not, what am I missing?
Thanks,
Brian
I've solved it! Instead of Settings.get(:site_url), I'm using configatron.site_url and it works!
Thank you!
Brian
