Common ruby patterns

• Ruby style guide (naming & formatting conventions)

To set a variable based on the condition of a value in another variable, use this pattern:

@var = other_var || "default value"

instead of this one:

if other_var
  @var = other_var
else
  @bar = "default value"
end

and if the other value might be coming from a Hash, use this:

@var = my_hash.fetch("other_var", "default value")
