    <p>I'm trying to implement auto complete in my rails application. I'm trying to pass ruby parameter via source of the jquery. Here is what I'm trying to do.</p> <pre><code>$( "#text" ).autocomplete({ appendTo: "#searchwrapper1", source: h_url+"product_details/menu_search_auto/" + &lt;%= "'#{params[:deptid]}'" %&gt; , open:function() { $(".ui-autocomplete").mCustomScrollbar1({ set_width : false, set_height : false, horizontalScroll : false, scrollInertia : 550, scrollEasing : "easeOutCirc", mouseWheel : "auto", autoDraggerLength : true, scrollButtons : { enable : false, scrollType : "continuous", scrollSpeed : 20, scrollAmount : 40 }, } </code></pre> <p>Here is my route.rb file</p> <pre><code>match "/product_details/menu_search_auto/:deptid"=&gt;'product_details#menu_search_auto' </code></pre> <p>and controller part is:</p> <pre><code>def menu_search_auto list=[] if(params[:deptid].to_s == 'all') b1=test4.where("name LIKE ?","#{params[:term]}%") else case params[:deptid].to_i when 1 b1=test1.where("name LIKE ?","#{params[:term]}%") when 2 b1=test2.where("name LIKE ?","#{params[:term]}%") when 3 b1=test3.where("name LIKE ?","#{params[:term]}%") else end end b1.each do |b1| list &lt;&lt; {"label"=&gt;b1.name, "value"=&gt;b1.name, "id"=&gt;b1.id} end respond_to do |format| format.json{render :json=&gt;list.to_json, :layout=&gt;false} end end </code></pre> <p>But neither I'm able to pass the parameter nor I'm getting any error.</p> <p>Please suggest me where I'm going wrong??</p>

    1. COmaybe you append some code (e.g. the product_details_controller#menu_search_auto and the routing for this action in your config/routes.rb ) so we can see something more. Another tip: add the server log (request and response) so we can see what is being passed and why.

    3. COcontroller and routes seem to be ok. i think the parameter is not passed because there's a problem with the embedded ruby (erb) in your js. Maybe it's better to change single and double quotes there and check if the parameter is just not set. Can you <%= puts SOME PARAMETER %> somewhere in your js to see if its interpreted. Does the js have the .erb extension?

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).
