generate html attributes only if condition is met

[jdescelliers]

Hi

I have a simple use case where I must include an anchor to an element only if one is set, for example:

.my-element[id="#{ generate_anchor }"]

Where generate_anchor would look something like this:

def generate_anchor(element)
  return if element[:anchor].blank?

  element[:anchor]
end

This is a fairly ugly solution as it would create blank id attributes everywhere.

Is there an more elegant way to do something like this:

.my-element([id="#{ generate_anchor }"]) - if element[:anchor].present?
