Hey all, I''ve just put together a little plugin to easily access the neighbours of a given model in a particular order. Read on if interested. Install: script/plugin install http://svn.viney.net.nz/things/rails/plugins/acts_as_ordered Usage: class Person < ActiveRecord::Base acts_as_ordered :order => ''first_name'' end Say you have people with first

Ask and ye shall receive. 1.1.3 now has a plugin test. i had one small issue with after_save being called, so i added the callback in. it works when i create a test app and run the unit tests so i think it has something to do with how i override the save method. if you have any suggestions, please feel free to comment. As far as the AR test suite goes...I''m not sure how this plugin

After a couple of thoughtful comments, I''ve made changes to acts_as_modified plugin. It no longer relies on after_find and after_initialize, which were both causing performance issues. Please check it out and let me know what you think, where you might recommend improvements or additional features and what not. One feature I do have planned (again, thanks to comments), but

Nothing special, just my first plugin. it came out of a request I saw on the list from someone who wanted to be able to tell if a model''s attributes had changed prior to being saved. Well, this plugin does just that (at least I hope it does). http://rubyforge.org/projects/actsasmodified/ Please see the README for details. Constructive comments and criticisms are appreciated.

I am running an lme model with the main effects of four fixed variables (3 continuous and one categorical – see below) and one random variable. The data describe the densities of a mite species – awsm – in relation to four variables: adh31 (temperature related), apsm (another plant feeding mite) awpm (a predatory mite), and orien (sampling location within plant – north or south). I have read

This plugin gives ActiveRecord the ability to do stricter date checking. Example: class Person < ActiveRecord::Base validates_date :date_of_birth end This will ensure that date_of_birth is a *valid* date. The date can be set initially as a string in any of the following formats: "2006-01-01" "1 Jan 06", or "1 Jan 2006" "1/1/06" # Day /

How do you tell if an foreign key attribute has been changed? For example, lets say you have a model with attribute table_a_id. Would you do this? def table_a_id=(value) if value != table_a_id @table_a_changed = true write_attribute ''table_a_id'', value end end def table_a=(value) if value != table_a @table_a_changed = true

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?

If the associated object of a has_one association has been loaded, it is resaved when the parent is saved. Eg: class Person < ActiveRecord::Base has_one :user end class User < ActiveRecord::Base belongs_to :person end p = Person.find(:first) p.save # As expected, nothing happens with the user association p.user # Loads the associated object p.save # As well as saving the person, the

Hi guys, I''m trying to make an AR model which accepts a string data (from a text input) in euro date format eg <input .... value = "23/01/2006"> ( 23 Jan 2006) Reading the example from RDoc... i tried to overwrite/overload/override the = function to write in the date.. Cant get it to work because .. i dont knoe what format should it accept.. i''ve tried

I''m developing database systems for clinical trials using Ruby on Rails. Some trials require ''double data entry'' as a form of validation; I need to incorporate this into my system and am having difficulties. My plan would be to have it work as follows: - Once a new record has been created, alongside the usual ''edit'' option there would be a

I''ve tried Time.parse() and DateTime.parse() but they interpret the date as US format. Is there any way to tell it to interpret as dd/mm/yyyy? -- Posted via http://www.ruby-forum.com/.

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

I am building a small app that reuires some clever text pattern matching... In my controller, I''ll have a string that I will want to parse out to a datetime and a message, a la Google Calendar Quick Add. Examples: 10/30/2006 7pm message 10-30-96 7:00 pm message 10/30/2006 19:00pm message ... You see what I''m getting at. For a v1.0 release, I CAN publish some standards for

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. For instance: //Returns all the posts into a collection called posts @posts = Post.find(:all) //Returns a specific post based on an id @post = Post.find(params[:id]) //How can i return the next

Hi, I have a table which has a column called due_date. Datatype of this column in mySQL is "Date". Here is what I extracted from schema.rb > t.column "due_date", :date My fixture tasks.yml file has the following line > due_date: 07/17/2006 My test_task.rb has the following line > assert_equal "07/17/2006", @task.due_date When I run

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

Hey there, There''s been a bit of work going on with Selenium and Rails recently, so I thought I may as well share what I came up with. Check out my blog post at http://blog.viney.net.nz/articles/2006/02/09/selenium-testing, grab the plugin and give it a whirl (be sure to read the README!). Basically, my approach was to make it possible to write Selenium tests in the same way that
