                Entrepreneur's Survival Guide to Coding
              
          
Filenames must be all-lowercase and cannot contain any spaces, ever.
Always save your code files before refreshing your browser.  Otherwise your code will not take effect.
All code repositories must be placed directly under your code folder.
Never put one code repository inside of another.  Each repository must be one level down inside the code folder.
Use lowercase for all code (HTML tags, CSS rules, Javascript, Ruby, etc.) unless specificially instructed otherwise.
View the Source, Luke!
Use the Web Inspector, Luke!
Coding is deterministic.  There is a cause for every effect.  Allow nothing to remain "magical" or "fuzzy".
You should be able to verbally explain your app's behavior when called upon.


## easy.rb
# Add this file to your config/initializers directory.
#
# Then you can do things like:
#
#   Product[5]          instead of Product.find_by(id: 5)
#   Product.sample      to pull a random Product row
#   Product.sample(3)   to pull three random Product rows (but they will be consecutive)
#
# Biggest part: automatic associations!

                Pattern: User Account Confirmation
              
          
    Problem

A user's true identity or email address must be verified before they are given full access to your application.
Solution

The system sends an email to the user's email address containing a unique, personalized url.  Visiting the url in a browser provides sufficient identity verification, since the url could only have been known to the person who received the email.
