Today's Goal is to setup a database for your social media app to save all of your awesome content.

Step 1 - Add a database connection to your application (Hint: It's totally okay to copy the environment.rb file from your Fwitter project.)

Step 2 - Set up your Gemfile with all of your gems - don't forget activerecord and sqlite3 (totally okay to copy from Fwitter again!)

Step 3 - Create a Rakefile and add the necessary lines of code (again, use Fwitter as a reference)

Step 4 - Now we need to modify your Content class so that it inherits from ActiveRecord::Base.

Step 5 - Create a migration for the items table rake db:create_migration NAME="create_content" and get in there to set up your up and down methods. (Look at your Fwitter migration). Don't forget to run your migration with rake db:migrate when you are done! The items table should include columns for:

:username
:content

Step 6 - You'll want to modify your controller action for creating new content. Remember that ActiveRecord is like a hash when creating new content. For Twitter:

Tweet.new("ianstwitterhandle", "My first tweet!")

becomes

tweet = Tweet.new(:username => "ianstwitterhandle", :status => "My first tweet!")
tweet.save

• Add a page that displays all of the content for a user based on the user. For example, going to "www.fwitter.com/users/ianstwitterhandle" will display all of the tweets where the username is "ianstwitterhandle", "www.fwitter.com/users/taylorswift13" will display all of the tweets where the username is "taylorswift13", etc. You'll need:
  • Dynamic URLs - check out the Sinatra documentation on routes here
  • ActiveRecord's where method - takes a condition as an argument and returns an array of items where the condition is true. ActiveRecord's where
