I have a controller method as such: def delete @category = Category.find_by_name(params[:name]) @element_id = @category.name Category.delete_all(["name = ?", @category.name]) end (For the purpose of this exercise, category names are unique) I have the corresponding delete.rjs file: if @element_id page.remove :id => @element_id page.visual_effect :highlight, ''categories'&...

Hi all, I''m using a selection-list / dropdown-list to choose an element in a number of grouped elements. Is there a way of passing an element_id to the form AND using the HTTP-''get''-method? I found that the <% start_tag %> has a :method-switch as an option, but it passes the arguments on like "/controller/action/?action=1". I would need something like "/controller/action/1" Can you help? -- Timo...

Often I have the need to set one class name to an element. I don''t care what was there before, just remove it and set it to the new class. I don''t see any easy way to remove all the class names or to set just one class name. Why is this? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on

Ok, that''s not the best subject line, but I couldn''t think of a concise way to describe what I''m trying to do. I''ve got two models. Grouping simply contains an id and a few other attributes (e.g. rating). A grouping can contain many elements which are stored the Element model. A set of elements is tied together by a grouping_id. An element can be one of

Can some one point me in the right direction? I''ve got several pages that will respond to user input by creating a new div in the content area. I want that new div to visually expand into view or flash with a background color rather than just appear. Thanks. -- Posted via http://www.ruby-forum.com/.

I''m trying to prevent double ajax requests when I have nested onclick handlers. I have a table with clickable column headings (for sorting by that column). I have onclick handlers on both the <th> and the <a> link so that clicking anywhere on the table heading should work. <th onclick="window.location.href=''http://foo?sort=foo'';">

Hello, I just can''t seem to find a way to extend a form dynamically in ROR. Say I am writing a recipe website. There is one form to enter the recipe. There is room for N number of ingredients (let''s say a text field for each ingredient name and selection list for the amount). What if the user wants to add more than N ingredients as he types them in? how do I do this without
