Structs within a Rails project

struct.rb

# If you're using Structs within a Rails project (in particular),
# you might run into an error about "superclass mismatch for class".

# You can solve this quite simply. Rather than doing this:

class SimpleContact < Struct.new(:name, :role, :company)
  def get_details
    ...
  end
end

# You should do this:

SimpleContact = Struct.new(:name, :role, :company)

class SimpleContact
  def get_details
    ...
  end
end
