So, Haml is *not* good at taking ugly code and making it pretty. Its good at
making you make sure you do good stuff.
def text_field_with_label(f, name, label_override = nil, options = {})
haml_tag :p do
puts f.label(name, label_override)
puts f.text_field(name, options)
end
end
then, you can do...
- text_field_with_label(f, :name)
- text_field_with_label(f, :address)
- text_field_with_label(f, :country)
.... etc....
making it even more dry, i'd probably do this.
def field_sets(f, *names)
names.each do |data|
name, label_override = *data
puts text_field_with_label(f, name, label_override)
end
end
- field_sets(f, :name, :address, :country, [:uri, "URI"], :postal_code)
Also, let's say we kept this simple and a little WET. What is so wrong with
doubling the lines.
Its less characters than the erb! So what if its on a new line?
