    <p>There was a question in the comments section of the AutoComplete Railscast that was unanswered and I need help with the same issue. <a href="http://railscasts.com/episodes/102-auto-complete-association-revised?view=comments#comment_159833" rel="nofollow noreferrer">http://railscasts.com/episodes/102-auto-complete-association-revised?view=comments#comment_159833</a></p> <p>I'm implementing jQuery-UI Autocomplete with the datasource coming from a Rails Controller which in turn is calling the Foursquare API. The Foursquare API requires 2 parameters (a "query" and a "lat/long" value).</p> <p>The Autocomplete widget's default param that it sends to the Rails controller is params[:term] which contains the "query". I need the Autocomplete Widget to pull the value from another text_field (let's call it the geocode_location field) and pass that as the "latlong" param. </p> <p>So effectively, the GET request to the Rails Controller would be </p> <p>Request URL:<a href="http://localhost:3000/foursquare?ll=37.7+-122.5&amp;term=McDonalds" rel="nofollow noreferrer">http://localhost:3000/foursquare?ll=37.7+-122.5&amp;term=McDonalds</a></p> <p>and not </p> <p>Request URL: URL:<a href="http://localhost:3000/foursquare?term=McDonalds" rel="nofollow noreferrer">http://localhost:3000/foursquare?term=McDonalds</a> </p> <p>Below is my current coffeescript file. I need to try to pass it extraParams or some way to let it know to pass a param named :latlong. How do I do that with Coffeescript and this type of data source?</p> <pre><code> $('[type="text"][name*="[location]"]').autocomplete source: $('[type="text"][name*="[location]"]').data('autocomplete-source') focus: (event, ui) -&gt; event.preventDefault() $(this).val ui.item.label select: (event, ui) -&gt; event.preventDefault() $(this).val ui.item.label $(this).siblings('[name*="[foursquare_id]"]').val ui.item.value </code></pre> <p>I'm not very familiar with Coffeescript syntax but really appreciate the help here. There is a similar question here but the data source for the autocomplete results is different. <a href="https://stackoverflow.com/questions/3803998/jquery-ui-autocomplete-with-extra-params-returned-data">jQuery UI - Autocomplete with extra params - returned data</a></p>

    1. COI'm not too familiar with coffeescript but I can provide a pure JS solution. Would that help?

    2. COYea that would be great. At this point - I think anything in the right direction would help. I will try my best to translate back to Coffeescript and post back if it works. Thanks @AndrewWhitaker

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
