Hi, I am thinking about writing an acts_as_fox plugin that defines an after_find callback method. If I do this what will happen if a user creates a model that acts_as_fox but this model has it''s own after_find callback method? I imagine that the model''s after_find method shadows the plugin''s after_find. Presumably both after_find callbacks would need...

Hi everybody I would like a function as the "before_save" method in the model. But it must be the opposite. When I take out data from the database through the model, I want to call a function before the data are available in the controller. Can anyone help me? ---- >>>> thx <<<< ---- -- Posted via http://www.ruby-forum.com/.

...#39;'t have a portfolio so I would like to only add that association when required. Obviously I could just return nil for that method, but it doesn''t feel right having that there in the first place. What''s the best way to get around this? I''ve looked at using eval in after_find to call the has_one, but couldn''t get it working.

Question for all: Right now i have a Table in a mySQL DB that has a row called Ingredients.

Hello, I am still reading Agile Web Developer pdf, it says about after_initialize and after_find. There is a Joe asks part when I read that they are special, however I didn''t really get the idea, why they are. On rubyonrails.org in the manual there is some sort description about their speciality, however their full descriptions are missing. What are the difference between after_in...

Just starting a new thread so that it''s easy to follow. I just submitted a patch at trac to add a new class method called "set_default_values" ( not a great name I think ), which lets you do all kinds of crazy stuff with setting default values. This ticket is at http://dev.rubyonrails.org/ticket/9093 and example pastie is at http://pastie.caboo.se/81925 It also lets you make

I am pondering the possibility of encrypting/decrypting some fields in a SQLite backend on-the-fly. The point of the message is not security, I know that''s broken, but whether there''s a technique that provides on-the-fly save/read filters. Of course the solution would need to work transparently in joins, so user.posts.last.title would do the right thing if title

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. Chris

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 haven''t had much time to devote...

My problem is that I have two classes where the eager loading isn''t working as well as I would hope... Here are my two classes: class Daynote < ActiveRecord::Base belongs_to :userplace class Userplace < ActiveRecord::Base has_many :daynote, :dependent => true When I show my userplaces, I want to get the associated daynotes with them, so I am doing: @userplace =

...How to get around the N+1? select problem and eager load Media? In the case of Show.all, Show and Media have a relation (yes bad schema) so I was thinking I could pull all the Media after a the Segment collection is loaded by Show and assign them to the Segments accordingly. But, while there is an after_find, this is applied after each object and not after the collection. Any ideas? Thanks

Seems like I do a fair amount of mocking ActiveRecord''s automatically generated routines when I''m testing controllers. Things like: @portalspace = PortalSpace.new :public_readable => true, :public_writable => true, :name => ''public'' @portalspace.stubs(:id).returns(203) PortalSpace.stubs(:find).with(203).returns(@portalspace)

Hi, I know that it is possible to execute code each time data is saved into a model by using the +validate+ method. However, is there also a way to execute code each time the data is accessed, not just when it is changed? Bye, Winsmith -- Posted via http://www.ruby-forum.com/.

Hi all, your thoughts appreciated: I''d like to encrypt one of my databases, as described in the first Rails book, by putting encrypt and decrypt methods on the :after_find, :before_save, and :after_save hooks in my model (what a lovely transparent way rails does things!). But unlike the book, I actually want to use real encryption, perhaps something from the OpenSSL library, something that requires a symmetric key, that I will ask the user to enter at login. Either t...

I created a model with some internal state derived from a combination of database and non-database data. Since I wanted to calculate these values once rather than every time they''re requested by the view, I calculated them in the initialize method and set some instance variables. However, I soon noticed that these values weren''t getting set when I retrieved data using the

I want to expire caches if a certain field of an item changes. How can I compare the item field''s old value to its new value (in the create, or after_save, etc. method)? thanks csn __________________________________ Yahoo! Mail - PC Magazine Editors'' Choice 2005 http://mail.yahoo.com

Is there any easy way to make a fancy looking form to take phone numbers. Something that looks like this: [ ] - [ ] - [ ] ext: [ ] Then when you submit it it''s combined into one string in the database. Optimally it would auto-switch from field-to-field after you fill each field. Has anyone seen anything like this in Rails? Thanks, Adam -- Posted via
