When I run bundle exec rake db:setup I get an error saying that rake doesn't know how to build that task. I then run bundle exec rake -T and see that db tasks are missing (all output below). How can I access the db tasks?

The following command is supposed to create a new database.
rails db:create
Where is this function defined? Or is this a pre-packaged function in rails?
It's in the databases.rake file of the framework:
namespace :create do
task all: :load_config do
ActiveRecord::Tasks::DatabaseTasks.create_all
end
ActiveRecord::Tasks::DatabaseTasks.for_each do |spec_name|
desc "Create #{spec_name} database for current environment"
task spec_name => :load_config do
db_config = ActiveRecord::DatabaseConfigurations.config_for_env_and_spec(Rails.env, spec_name)
ActiveRecord::Tasks::DatabaseTasks.create(db_config.config)
end
end
end
Whenever you doubt or want to know where a task has been defined, you can use the rails -W (or rake) command, passing the task:
$ rails -W db:create
rails db:create /path/databases.rake:26:in `block in <top (required)>'
rails db:create:all /path/databases.rake:20:in `block (2 levels) in <top (required)>'
Note it was introduced in the version 0.9 of Rake. This might or might not work depending on the versions which you're working with.
Some of my rSpec tests are failing and I suspect it's due to the test database not being cleared out. When I try to run rake db:test:prepare, I'm getting the error below (i'm in Rails 3.2). Clearly, this looks like some kind of Postgres issue, looks like the rake task is trying to drop the test database so it can repopulate it. Production database schema loads fine.
I've looked for the rake task in lib/tasks/ but I haven't been able to find it. Anyone have any idea on what's going on?

Figured it out. My database.yml file for the development environment was set like this:
database: <%= ENV['DATABASE_NAME_TEST'] %>
The rake task was looking for an environmental variable that did not exist.
In a Rails 4 app, I want precompiled assets to have copies of some assets to be available with a non fingerprinted filename. The app is deployed on Heroku.
I have the following rake task in place:
namespace :app do
task :nonfingerprint_assets => :environment do
manifests = Rails.application.config.assets[:precompile]
manifests = manifests.slice(1, manifests.length)
assets = Dir.glob(File.join(Rails.root, 'public/assets/**/*'))
regex = /(-{1}[a-z0-9]{32}*\.{1}){1}/
assets.each do |file|
next if File.directory?(file) || file !~ regex
source = file.split('/')
source.push(source.pop.gsub(regex, '.'))
non_digested = File.join(source)
if manifests.any? {|m|
if m.is_a? Regexp
m.match non_digested
else
m.ends_with?(non_digested)
end
}
puts "** copy source: #{file}"
puts "** copy destination: #{non_digested}"
FileUtils.cp(file, non_digested)
end
end
end
end
Rake::Task['assets:precompile'].enhance do
puts "Invoke nonfingerprint_assets"
Rake::Task['app:nonfingerprint_assets'].invoke
end
This rake task is working fine on my local machine even in production environment. It creates a file in public/assets/application.js which is the copy of the same file with a digest in its name.
When I deploy this code to heroku I get the following error message which I don't understand:
-----> Preparing app for Rails asset pipeline
Running: rake assets:precompile
[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_

I'm running clockwork in the background using Clockworkd. If I just run clockwork, it executes the rake command successfully. If I run it via clockworkd, it produces an error. I'm not sure why it isn't working. Any advice / suggestions would be appreciated.

The process running your rake get_updates task may not be in the same working directory as your Rakefile is located.
You could either Dir.chdir '/dir/containing/Rakefile/', or else explicitly pass the path to the Rakefile using the -f option:
every(1.hour, 'Get Updates') do
Dir.chdir '/dir/containing/Rakefile/'
`rake get_updates`
end
I'm trying to solve a problem I'm having lately, deploying from a github production branch with cap: production deploy:migrations to my server.
I saw a potential solution was to follow this page: http://www.kudelabs.com/2012/03/28/rails-3-2-cap-deploy-with-assets
However I got errors at the rake assets:precompile part, running it locally. Terminal suggested I do
bundle exec rake assets:precompile, which I did, but I got the following:

Can anyone tell me where the problem might be?
If this is an initial deploy, try to remove
load 'deploy/assets'
Then try to
cap deploy:setup
cap deploy:cold
In this case you app will be deployed but without any assets :)
Then you need to add this:
#to the top of your deploy.rb namespace :deploy block
namespace :assets do
task :precompile, :roles => :web do
from = source.next_revision(current_revision)
if capture("cd #{latest_release} && #{source.local.log(from)} vendor/assets/ lib/assets/ app/assets/ | wc -l").to_i > 0
run_locally("rake assets:clean && rake assets:precompile")
run_locally "cd public && tar -jcf assets.tar.bz2 assets"
top.upload "public/assets.tar.bz2", "#{shared_path}", :via => :scp
run "cd #{shared_path} && tar -jxf assets.tar.bz2 && rm assets.tar.bz2"
run_locally "rm public/assets.tar.bz2"
run_locally("rake assets:clean")
else
logger.info "Skipping asset precompilation because there were no asset changes"
end
end
task :symlink, roles: :web do
run ("rm -rf #{latest_release}/public/assets &&
mkdir -p #{latest_release}/public &&
mkdir -p #{shared_path}/assets &&
ln -s #{shared_path}/assets #{latest_release}/public/assets")
end
end
Then recheck if you have this in your production.rb
config.serve_static_assets = false
# Compress JavaScripts and CSS
config.assets.compress = true
# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = false
# Generate digests for assets URLs
config.assets.digest = true
After all this work, change some thing in you assets, for example add new line in application.css, this will tell "task :precompile" to realy precomlile and upload new assets, because new assets was added..
