Installing Devise/User Model - Application Treebook no longer opens

Hi, I installed devise and re-watched the video 3 times to make sure I did not miss any steps or code, my application no longer loads the message I get from the server is that it can't connect to the local host. In the video where Jason first types in the code 'rails generate devise user' I don't receive any of the feedback with "create", "insert", etc.,. This is what I receive, if anyone can offer any help I greatly appreciate it because I'm not able to go any further now.

rails generate devise user Usage: rails new APP_PATH [options]

Options: -r, [--ruby=PATH] # Path to the Ruby binary of your choice # Default: /usr/local/rvm/rubies/ruby-1.9.3-p392/bin/ruby -b, [--builder=BUILDER] # Path to a application builder (can be a filesystem path or URL) -m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL) [--skip-gemfile] # Don't create a Gemfile [--skip-bundle] # Don't run bundle install -G, [--skip-git] # Skip Git ignores and keeps -O, [--skip-active-record] # Skip Active Record files -S, [--skip-sprockets] # Skip Sprockets files -d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db/sqlserver/jdbcmysql/jdbcsqlite3/jdbcpostgresql/jdbc) # Default: sqlite3 -j, [--javascript=JAVASCRIPT] # Preconfigure for selected JavaScript library # Default: jquery -J, [--skip-javascript] # Skip JavaScript files [--dev] # Setup the application with Gemfile pointing to your Rails checkout [--edge] # Setup the application with Gemfile pointing to Rails repository -T, [--skip-test-unit] # Skip Test::Unit files [--old-style-hash] # Force using old style hash (:foo => 'bar') on Ruby >= 1.9

Runtime options: -f, [--force] # Overwrite files that already exist -p, [--pretend] # Run but do not make any changes -q, [--quiet] # Suppress status output -s, [--skip] # Skip files that already exist

Rails options: -h, [--help] # Show this help message and quit -v, [--version] # Show Rails version number and quit

Description: The 'rails new' command creates a new Rails application with a default directory structure and configuration at the path you specify.

You can specify extra command-line arguments to be used every time
'rails new' runs in the .railsrc configuration file in your home directory.

Note that the arguments specified in the .railsrc file don't affect the
defaults values shown above in this help message.

Example: rails new ~/Code/Ruby/weblog

This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.

Hi Jennifer!

This might sound like a silly question, but are you running > rails generate devise user from within the directory of your application?

No worries! I just tried it and it worked!! This may sound silly, why is it necessary to run it within the directory (if you don't mind)?

Great to hear!

Well, when you run rails new project, it generates a new directory specific to that project where are the project-specific files are stored. So, if you want to create a model for it, you should be in the project's directory.

If you have multiple projects, you just switch to the home directory for that specific project.

Oh ok, I didn't switch to the home directory. Much appreciated Rhys!

Best,

Jenn

Yep, if I'm working on the treebook project, I should be in the treebook directory:

MacbookPro:treebook username$ rails generate devise user

If I'm working on a project called bumblebee then I should be in the bumblebee directory

MacbookPro:tbumblebee username$ rails generate devise user

Got it!
