Can''t figure out how duplicate routes are differentiated by rails ... Read routing from inside out and API as well as a few tutorials but still don''t get it!!! For example... routes.rb resources :minisections do resources :questions end rake routes: minisection_question GET /minisections/:minisection_id/questions/:id(.:format) questions#show

Hi, I''m new in developint rails (but I love rails). I would like to react on changing a field in the view (no model field) from a selection box to show the number of rows (which I used in the controller). In the controller I read the params-hash: ... @rowsperpage = params[''rowsperpage''].to_i ... In the view I have the field, where I like to react directly. ...

Hi, Yet another newbie here... I''m writing an appliction in Rails, and I''ve Ajaxified my select boxes so they update dynamically. I used the "observe_field" method to monitor changes to my select box.

Hi, I know that to make a dropdown box automatically submit when you change the value, you do this: <select ..... onchange="this.form.submit();"> BUT i''ve got an ajax form, and if i do the above trick, it simply reloads the ajax partial into the whole screen, rather than into the div where it is meant to go. I''ve already got it all working so that if you click

I have just started using RoR and am creating some select boxes on my form with the following code: <%= select_tag(options_from_collection_for_select(Owner.all, :id, :fname)) %> My problem is that it does NOT return the first record from the table, but just the second and succeeding records. Does anyone have any ideas on how I can get the first record included in the select box? Thanks.

I would like to pass the value selected in a select statement back so that I can use it in the controller, through using a remote_function call, and I cannot figure out what I am doing wrong: view rhtml: <select id="widgets_id" name="widgets[id]" onchange="<%= remote_function( :update => "parts", :url=> { :action => :loadParts } )

Hello, I''m trying to get a select field to update a view via the ''onchange'' option. I''ve seen examples of it here in the forum where people hardcode the forms and use javascript to trigger the change (and nearly all have complained that it''s a hack) and I''m wondering if anyone has a more elegant solution using the embedded ruby methods?

Goal: I want to auto-send a form whenever any field changes. The page will be updated "via Ajax", so standard submission is cancelled. Idea: Add onchange="document.forms[0].submit();" to every field Problem: Can not cancel form submission.
