Overview

the to_gmaps4rails method accepts a block to customize:

  • infowindow

  • picture

  • title

  • sidebar

  • json

This works this way:

@json = User.all.to_gmaps4rails do |user, marker|
  marker.infowindow render_to_string(:partial => "/users/my_template", :locals => { :object => user}).gsub(/\n/, '').gsub(/"/, '\"')
  marker.picture({
                  :picture => "http://www.blankdots.com/img/github-32x32.png",
                  :width   => "32",
                  :height  => "32"
                 })
  marker.title   "i'm the title"
  marker.sidebar "i'm the sidebar"
  marker.json({ :id => user.id })
end

For backward compability, a mere string could be passed:

@json = User.all.to_gmaps4rails do |user, marker|
  "\"id\": #{user.id}"
end
