Question

I’ve got an object/param that I’m saving into my database. But while I do that I’d like to get the first row in that object to do some Javascript things with. So what I’m receiving in my view from the Javascript object(Which is being send by an AJAX request) if i do this:

<% @markers.each do |marker| %>
  <%= marker%>
<% end %>

Is this record:

["triplocations_attributes", {"0"=>{"latlng"=>"53.20192541983673, 5.535024029052693", "title"=>"first", "description"=>"first"}, "1"=>{"latlng"=>"53.18896756239149, 5.536568981445271", "title"=>"2nd", "description"=>"2nd"}}]

Now, what I would like is to get the latlng from the first(0) row. Can anyone tell me how?

What I’ve tried so far didn’t work:

<%= marker.triplocations_attributes %>
<%= marker[0].title %>
<%= marker.title %>

Answer 1

It seems reasonable to suppose that you have something like

class Marker < ActiveRecord::Base
  has_many :triplocations
  ...
end

In that case you need to access

marker.triplocations[0].title
marker.triplocations[0].description
...
