module ErbTemplatable

Simple wrapper around ERB Intended to simplify templates usage

by establishing few conventions

Module should be included to make method available

class BrandNewClass

include ErbTemplatable

# this method will render file
#   parent_dir/templates/mozzarella.html.erb
#   where parent_dir - the location of BrandNewClass
def want_the_template
  erb_template("mozzarella")
end

# this method will render file
#    app/models/sausages/cheeses/camembert.html.erb
#    with no biding attached
def explicit_template
  erb_template("camembert.html.erb", dir_name="app/models/sausages", "cheeses/", nil)
end

end
