Question

I’m doing a Rails project for class where a user can enter a search term, the results are displayed (images), then the user can click on an image to get a larger version of it.

On the larger version page, I have a button_to :back.

<%= button_to "Back", :back %>

But when I hit the button, the image results page it returns to shows the default images, not the ones returned from the search. I need to be able to pass params[:search_term] back to the previous page (as without a :search_term value, the default images are returned).

I tried this:

<%= button_to "Back", :back, :search_term => params[:search_term] %>

And when viewing the page source, it looks like it should pass the parameter back:

   <form action="http://localhost:3000/albums/7/add" class="button_to" method="post">
   <div>
   <input search_term="puppy" type="submit" value="Back" />
   <input name="authenticity_token" type="hidden" value="lkjsakvgjwhatever" />
   </div></form>

The authenticity token gets returned back, but my search_term doesn’t.

EDIT:

Here’s the view:

<%= image_tag("http://farm#{@pic["farm"]}.staticflickr.com/#{@pic["server"]}/#{@pic["id"]}_#{@pic["secret"]}_c.jpg") %>
<br><br>
<%= @pic["title"] %>'

<br><br>
<br><br>

<%= button_to "Back", :back, {:search_term=> params[:search_term]} %>

You have to change the action of the form. Something like this

<%= form_for(@model, :url => 'YOURURL',  :method => 'get') do %>
