RandomKeygen is a free mobile-friendly tool that offers randomly generated keys and passwords you can use to secure any application, service or device. KEY RandomKeygen - The Secure Password & Keygen Generator. Dec 22, 2017 Rails 5.1 introduced Encrypted Secrets to help simplify the management of your application secrets (things such as service credentials and the secretkeybase). This article details the feature and its usage. Aug 06, 2013 Hi, I am using devise in my rails 4 app. In my gem file like so: gem 'devise', github: 'plataformatec/devise' When I run rails generate devise:install I get the below errors: Devise.secretkey was not set. Please add the following to you.
1 Upgrading to Rails 4.1
Technically the purpose of secrectkeybase is to be the secret input for the application’s keygenerator method (check Rails.application.keygenerator). The application’s keygenerator, and thus secretkeybase, are used by three core features within the Rails framework. Jcoyne changed the title Missing devise secret key with Rails 5.2.0.beta1 Missing devise secret key with Rails 5.2.0.beta2 Nov 28, 2017 gencer added a commit to gencer/devise that referenced this issue Nov 30, 2017.
If you're upgrading an existing application, it's a great idea to have good testcoverage before going in. You should also first upgrade to Rails 4.0 in case youhaven't and make sure your application still runs as expected before attemptingan update to Rails 4.1. A list of things to watch out for when upgrading isavailable in theUpgrading Ruby on Railsguide.
2 Major Features2.1 Spring Application Preloader
Spring is a Rails application preloader. It speeds up development by keepingyour application running in the background so you don't need to boot it everytime you run a test, rake task or migration.
New Rails 4.1 applications will ship with 'springified' binstubs. This meansthat
bin/rails and bin/rake will automatically take advantage of preloadedspring environments.
Running rake tasks:
Running a Rails command:
Spring introspection:
Have a look at theSpring README tosee all available features.
See the Upgrading Ruby on Railsguide on how to migrate existing applications to use this feature.

Feedback
You're encouraged to help improve the quality of this guide.
Win 7 home premium 64 bit key generator. Please contribute if you see any typos or factual errors. To get started, you can read our documentation contributions section.
You may also find incomplete content or stuff that is not up to date. Please do add any missing documentation for master. Make sure to check Edge Guides first to verify if the issues are already fixed or not on the master branch. Check the Ruby on Rails Guides Guidelines for style and conventions.
If for whatever reason you spot something to fix but cannot patch it yourself, please open an issue.
And last but not least, any kind of discussion regarding Ruby on Rails documentation is very welcome on the rubyonrails-docs mailing list.
This tutorial assumes you have basic Rails knowledge from reading the Getting Started with Rails Guide.
1 Command Line Basics
There are a few commands that are absolutely critical to your everyday usage of Rails. In the order of how much you'll probably use them are:
rails console
rails server
rails test
rails generate
rails db:migrate
rails db:create
rails routes
rails dbconsole
rails new app_name
You can get a list of rails commands available to you, which will often depend on your current directory, by typing
rails --help
. Each command has a description, and should help you find the thing you need.
Let's create a simple Rails application to step through each of these commands in context.
1.1 rails new
The first thing we'll want to do is create a new Rails application by running the
rails new
command after installing Rails.
You can install the rails gem by typing
gem install rails
, if you don't have it already.
Rails will set you up with what seems like a huge amount of stuff for such a tiny command! You've got the entire Rails directory structure now with all the code you need to run our simple application right out of the box.
1.2 rails server
The
rails server
command launches a web server named Puma which comes bundled with Rails. You'll use this any time you want to access your application through a web browser.
With no further work,
rails server
will run our new shiny Rails app:
With just three commands we whipped up a Rails server listening on port 3000. Go to your browser and open http://localhost:3000, you will see a basic Rails app running.
You can also use the alias 's' to start the server:
rails s
.
The server can be run on a different port using the
-p
option. The default development environment can be changed using -e
.
The
-b
option binds Rails to the specified IP, by default it is localhost. You can run a server as a daemon by passing a -d
option.
1.3 rails generate
The
rails generate
command uses templates to create a whole lot of things. Running rails generate
by itself gives a list of available generators:
You can also use the alias 'g' to invoke the generator command:
rails g
.
You can install more generators through generator gems, portions of plugins you'll undoubtedly install, and you can even create your own!
Using generators will save you a large amount of time by writing boilerplate code, code that is necessary for the app to work.
Let's make our own controller with the controller generator. But what command should we use? Let's ask the generator:
All Rails console utilities have help text. As with most *nix utilities, you can try adding
--help
or -h
to the end, for example rails server --help
.
The controller generator is expecting parameters in the form of
generate controller ControllerName action1 action2
. Let's make a Greetings
controller with an action of hello, which will say something nice to us.
What all did this generate? It made sure a bunch of directories were in our application, and created a controller file, a view file, a functional test file, a helper for the view, a JavaScript file, and a stylesheet file.
Check out the controller and modify it a little (in
app/controllers/greetings_controller.rb
):
Then the view, to display our message (in
app/views/greetings/hello.html.erb
):
Fire up your server using
rails server
.
The URL will be http://localhost:3000/greetings/hello.
With a normal, plain-old Rails application, your URLs will generally follow the pattern of http://(host)/(controller)/(action), and a URL like http://(host)/(controller) will hit the index action of that controller.
Rails comes with a generator for data models too.
For a list of available field types for the
type
parameter, refer to the API documentation for the add_column method for the SchemaStatements
module. The index
parameter generates a corresponding index for the column.
But instead of generating a model directly (which we'll be doing later), let's set up a scaffold. A scaffold in Rails is a full set of model, database migration for that model, controller to manipulate it, views to view and manipulate the data, and a test suite for each of the above.
We will set up a simple resource called 'HighScore' that will keep track of our highest score on video games we play.
The generator checks that there exist the directories for models, controllers, helpers, layouts, functional and unit tests, stylesheets, creates the views, controller, model and database migration for HighScore (creating the
high_scores
table and fields), takes care of the route for the resource, and new tests for everything.
The migration requires that we migrate, that is, run some Ruby code (living in that
20130717151933_create_high_scores.rb
) to modify the schema of our database. Which database? The SQLite3 database that Rails will create for you when we run the rails db:migrate
command. We'll talk more about that command below.
Let's talk about unit tests. Unit tests are code that tests and makes assertionsabout code. In unit testing, we take a little part of code, say a method of a model,and test its inputs and outputs. Unit tests are your friend. The sooner you makepeace with the fact that your quality of life will drastically increase when you unittest your code, the better. Seriously. Please visitthe testing guide for an in-depthlook at unit testing.
Let's see the interface Rails created for us.
Go to your browser and open http://localhost:3000/high_scores, now we can create new high scores (55,160 on Space Invaders!)
1.4 rails console
The
console
command lets you interact with your Rails application from the command line. On the underside, rails console
uses IRB, so if you've ever used it, you'll be right at home. This is useful for testing out quick ideas with code and changing data server-side without touching the website.
You can also use the alias 'c' to invoke the console:
rails c
.
You can specify the environment in which the
console
command should operate.
If you wish to test out some code without changing any data, you can do that by invoking
rails console --sandbox
.
1.4.1 The app and helper objects
Inside the
rails console
you have access to the app
and helper
instances.
With the
app
method you can access named route helpers, as well as do requests.
With the
helper
method it is possible to access Rails and your application's helpers.
1.5 rails dbconsole
rails dbconsole
figures out which database you're using and drops you into whichever command line interface you would use with it (and figures out the command line parameters to give to it, too!). It supports MySQL (including MariaDB), PostgreSQL, and SQLite3.
You can also use the alias 'db' to invoke the dbconsole:
rails db
.
1.6 rails runner
runner
runs Ruby code in the context of Rails non-interactively. For instance:
You can also use the alias 'r' to invoke the runner:
rails r
.
You can specify the environment in which the
runner
command should operate using the -e
switch.
You can even execute ruby code written in a file with runner.
1.7 rails destroy
Think of
destroy
as the opposite of generate
. It'll figure out what generate did, and undo it.
You can also use the alias 'd' to invoke the destroy command:
rails d
.
1.8 rails about
rails about
gives information about version numbers for Ruby, RubyGems, Rails, the Rails subcomponents, your application's folder, the current Rails environment name, your app's database adapter, and schema version. It is useful when you need to ask for help, check if a security patch might affect you, or when you need some stats for an existing Rails installation.
1.9 rails assets:
You can precompile the assets in
app/assets
using rails assets:precompile
, and remove older compiled assets using rails assets:clean
. The assets:clean
command allows for rolling deploys that may still be linking to an old asset while the new assets are being built.
The name may sound scary at first, but the mechanism is relatively simple to understand.Symmetric keyTo better understand how works a system based on asymmetric keys, it is necessary to begin by describing what is a system of a symmetric key. Almost all of the existing tokens are exchanged through this mechanism. Symmetric key cryptography using random key generator pdf download. The encryption of asymmetric key is a central mechanism in bitcoin operations and cryptocurrencies in general.
If you want to clear
public/assets
completely, you can use rails assets:clobber
.
1.10 rails db:
The most common commands of the
db:
rails namespace are migrate
and create
, and it will pay off to try out all of the migration rails commands (up
, down
, redo
, reset
). rails db:version
is useful when troubleshooting, telling you the current version of the database.
More information about migrations can be found in the Migrations guide.
1.11 rails notes
Rails Secret Key Base
rails notes
searches through your code for comments beginning with a specific keyword. You can refer to rails notes --help
for information about usage.
By default, it will search in
app
, config
, db
, lib
, and test
directories for FIXME, OPTIMIZE, and TODO annotations in files with extension .builder
, .rb
, .rake
, .yml
, .yaml
, .ruby
, .css
, .js
, and .erb
.
1.11.1 Annotations
You can pass specific annotations by using the
--annotations
argument. By default, it will search for FIXME, OPTIMIZE, and TODO.Note that annotations are case sensitive.
1.11.2 Tags
You can add more default tags to search for by using
config.annotations.register_tags
. It receives a list of tags.
1.11.3 Directories
You can add more default directories to search from by using
config.annotations.register_directories
. It receives a list of directory names.
1.11.4 Extensions
You can add more default file extensions to search from by using
config.annotations.register_extensions
. It receives a list of extensions with its corresponding regex to match it up.
1.12 rails routes
rails routes
will list all of your defined routes, which is useful for tracking down routing problems in your app, or giving you a good overview of the URLs in an app you're trying to get familiar with.
1.13 rails test
A good description of unit testing in Rails is given in A Guide to Testing Rails Applications
Rails comes with a test framework called minitest. Rails owes its stability to the use of tests. The commands available in the
test:
namespace helps in running the different tests you will hopefully write.
1.14 rails tmp:
The
Rails.root/tmp
directory is, like the *nix /tmp directory, the holding place for temporary files like process id files and cached actions.
The
tmp:
namespaced commands will help you clear and create the Rails.root/tmp
directory:
rails tmp:cache:clear
clearstmp/cache
.rails tmp:sockets:clear
clearstmp/sockets
.rails tmp:screenshots:clear
clearstmp/screenshots
.rails tmp:clear
clears all cache, sockets, and screenshot files.rails tmp:create
creates tmp directories for cache, sockets, and pids.
1.15 Miscellaneous
rails stats
is great for looking at statistics on your code, displaying things like KLOCs (thousands of lines of code) and your code to test ratio.rails secret
will give you a pseudo-random key to use for your session secret.rails time:zones:all
lists all the timezones Rails knows about.
1.16 Custom Rake Tasks
Custom rake tasks have a
.rake
extension and are placed inRails.root/lib/tasks
. You can create these custom rake tasks with therails generate task
command.
To pass arguments to your custom rake task:
You can group tasks by placing them in namespaces:
Invocation of the tasks will look like:
If you need to interact with your application models, perform database queries, and so on, your task should depend on the
environment
task, which will load your application code.
2 The Rails Advanced Command Line
More advanced use of the command line is focused around finding useful (even surprising at times) options in the utilities, and fitting those to your needs and specific work flow. Listed here are some tricks up Rails' sleeve.
2.1 Rails with Databases and SCM
When creating a new Rails application, you have the option to specify what kind of database and what kind of source code management system your application is going to use. This will save you a few minutes, and certainly many keystrokes.
Getting together with some of your hunter friends could be just the ticket you need to topple that challenge. Trust us — no one's going to judge you for needing a hand every now and then.
Can't quite beat that high-ranked monster on your own?
Rails 5 Generate Secret Key Card
Let's see what a
--git
option and a --database=postgresql
option will do for us:
We had to create the gitapp directory and initialize an empty git repository before Rails would add files it created to our repository. Let's see what it put in our database configuration:
It also generated some lines in our
database.yml
configuration corresponding to our choice of PostgreSQL for database.
The only catch with using the SCM options is that you have to make your application's directory first, then initialize your SCM, then you can run the
rails new
command to generate the basis of your app.
