What is happing now is that it lists all names…and if I type in some
letters and click return …the whole page is getting rendered
again…in the list
Your javascript is not actually doing anything with the value of the
query text field (take a look at the params received by your code).
The get method takes as its optional 2nd argument a map or string of
data, ie in your case {query: $(this).val()} (since this is in that
event handler, ‘this’ will be the text field.
You also want to ask rails to render without a layout. You can either
do this with render :layout => false or you can set the layout at the
controller level
<[email protected] do |client|%> #coffee
jQuery ($) ->
$("#query").change ->
$.get “search”, (data) ->
$("#results").html data

SELECT clients.* FROM clients WHERE (name like ‘%%’)
=> true…
Can you please tell me some more about… as I am not really familiar
with js/coffee
$.get “search”, (data) ->
As I understand it in (data) should be the value of :query giving it to
the action search
@clients = Client.where(“name like ?”, “%#{params[:query]}%”)
But this is not happening

This is a little unclear to me.

actually, no, here data is the parameter that is passed to your ajax
callback function (which contains the response from the server).
@clients = Client.where(“name like ?”, “%#{params[:query]}%”)
But this is not happening
When you make an ajax request like that, you need to actually set the
parameters that you want to pass. Right now you’re passing no
parameters, so params[:query] is nil
would pass the value of the field with id query (and since this code
is being called from the change event handler attached to the text
field, you can shorten that slightly to $(this).val() instead of $
(‘#query’).val()
Here is what you need to do (there are multiple ways of doing it, I am
showing you an easy one, definitely not the best one).
You actually have 2 different views, one that renders the search page
and
another one that renders only the list content, which is invoked through
jquery. The behavior you see now is because you use just one view.
@clients = Client.where("name like ?", "%#{params[:query]}
%").limit(5)
render :layout => false
end
and your coffeescript
#coffee
jQuery ($) ->
$("#query").change ->
searchText = $("#query").val()
# Need to uriEncode searchText here, there should be a good jquery
way
to do so.
$.get "/path to your route/results?query=#{searchText}", (data) ->
$("#results").html data
Please keep in mind that I haven’t done anything in rails for quite some
time, so the above code is not perfect and probably contains bugs. But
it
should show the general idea.
