similar to: How to fetch the previous or next record

Hi, Quick question (which means that I think there should be an easy answer)... When I am in the "show" view, I''d like to add 2 links, one for previous and one for next record so that the user can go on to the next "result" without having to go back to the ''list'' of results. However, I can''t find my way about this problem :-S

Does ActiveRecord offer a simple solution to get previous/next records relative to a certain record? For instance, say I have this table: PEOPLE id | name 1 | john 2 | mary 3 | bob Using p = Person.find(2), is it possible to get the previous (john) and next (bob) records using perhaps something like p.previous and p.next? If not, how can I do this without resorting to ugly queries? Thanks in

Hi, I know about pagination but dont want to use that option if it all possible. How in a collection of posts can i check if the there is a next item in the collection and then add that an object.

Hello, In a list view, I''m trying to list a subset of a table''s records based on a partial search value. So if the user enters " Smith " then the view should list all records with " Smith " as the value of the relevant field. I have this partial listing of the Find view: Enter name to find <%= start_form_tag :action =>

A quick note about acts_as_modified, acts_as_ordered and validates_date_time. If you are using any of those plugins you should update them. They''ve all had improvements/bug fixes. Also, acts_as_modified is now being maintained by both Chris Hall and myself. http://svn.viney.net.nz/things/rails/plugins/acts_as_ordered http://svn.viney.net.nz/things/rails/plugins/acts_as_modified

Hi, While viewing part of a long list of records, the user may want to do a Find of a specific record (for example, find_by_name). The found record is then displayed using the list view. I''ve searched the wiki and couldn''t find a sample or information that will help directly in implementing this function. Any pointers? Thanks! gk -- Posted via http://www.ruby-forum.com/.

Hi, When I "smbmount" a shareable drive on my linux box, the result of the "ls" command is often false.

Hey all, I got annoyed recently that I couldn''t specifiy multiple chunks of test setup and teardown code that get executed for each test. You''re currently limited to just one setup method (unless I''m much mistaken). Anyway, I just wrapped up my solution in a plugin. The answer: use blocks! class Test::Unit::TestCase # This is overridden by the subclass and will

Hello all. I don''t suppose some enterprising soul with much more skill than me has whipped up a "validates_dateness_of" (Complete with leap year calculations) method for use with all the other validation methods and wishes to spread much much joy?

Hey all, I''d like to abstract the process of updating different portions of the page after an Ajax request has taken place. Rather than simply putting the extra view logic in the standard rjs template, it seems to give better separation if there is a split between the core view logic (ie, inserting a row in a table), and updating any associated portions of the page. Is this possible? I
