Hi I have an problem about before_* callbacks. I have a model named: Event And I don''t want anyone to destroy or update any records in Event model. So: [code] class ActiveRecord::Base before_destroy :log_illegal_operations before_update :log_illegal_operations private def log_illegal_operations Event.create(...

Hi, I have a Product and a corresponding Keyword (1:1 via belongs_to and has_one). I want to ensure, that two attributes (:name) of the two models alway stay in sync. What''s the easiest way to accomplish that? I did play around with before_/after_save hooks and with AR::Observers but in the end I''d always get infinite recursion... Thanks, Timo

Hi, I have a very sime app. I need to create as many records in the db as the selected checkboxes (named :isselected) in the view. Here is the code snippet from the controller: isselectedhash = params[:isselected] for mod in isselectedhash.keys @issue = Issue.new(params[:issue]) @issue.state = ''NEW'' @issue.mod_id = isselectedhash[mod] # this gets

What''s the better thing to do in a before_save if you don''t want the save to continue? raise an exception, or do an errors.add or both? Thanks, Chris Nolan.ca http://kweschun.com/ - Do you have a Kweschun?

I''d like to be able to enable/disable the automatic indexing of documents acts_as_ferret does. Something like MyModel.disable_indexing MyModel.enable_indexing would be perfect. I need this because I do some indexing that requires visiting the parents of the model objects and my import method imports the children first, so the information isn''t there yet. I''d like to

In the Rails Recipes book the recipe "Keeping track of who did what" explains how to do decoupled observing of models. In my application I''d like to do a similar thing but watching the controllers. For example, when somebody hits the login method of the Security controller, I''d like to make a note of it. In this case I could observe the User model and watch for

I''m new to Rails3, and I''m just trying to get one last thing to work before I call it a night. The situation is the following (please if the code is horrible, just let me know, still learning): I want to log a dive. I might have a new location on that dive at which point I have to create a new Location, and then create the dive. A dive has_one location. A location has_many

Hi, I''m doing a <model_name>.update(....) but I''m noticing that my before_update callback is not being called. If I do a find and then a save!, I notice that it is called. The problem with a find and save in my case is that I''m not able to set all my attributes in one shot by saving params["user"] and since I can''t do this, my overloaded e...

...einitialize the user object by using the params["user"] but I''d like to intialize it in a way that calls my model''s equality operator to do some sepecial initializations defined as so: # In my model def user=(user) ... end ----- I need to somehow invoke the after_* and before_* callbacks and these apparently don''t get invoked if I do an update like so: user.update(....). It seems like I must do a user.save! to invoke them. Thanks, Saureen. -- Posted via http://www.ruby-forum.com/.

With after triggers in Postgres, there are special NEW and OLD vars accessible to trigger functions. Any such thing in Rails? Or would it entail doing something like setting a class var in before_update? Jack -- Posted via http://www.ruby-forum.com/.

Hi all, if I have a has_many and belongs_to relations like this category has many articles article belongs to category is there a way I can specify the order of articles when pulling them up with @some_category.articles ? Many thanks in advance! -- Nicky

hi, i''m just getting started using switchtower for deployment. i''m working with a small team of 3 and a hosted subversion repository. i have switchtower working, but i need to create two custom tasks and have those tasks run at deployment. 1) copy a working dispatch.fcgi from another folder, and 2) copy db/database.example to db/database.yml here is what i''ve tried,

I haven''t had a chance to work on fixing multiple controller view paths recently. My original patch attempt was: http://dev.rubyonrails.org/ticket/8582 It was rejected due to the fact that it was fixing the symptom more than the problem. However, I think it''s critical that this problem get fixed, otherwise the whole concept of view_paths is severely neutered and

I have a few projects with large directories (say, user-uploaded files) that make using Capistrano a bit awkward. However, I suspect that I may have reached the "write a custom task" level. (I suppose I''m just thinking out loud, here...) It seems as though I''d want this directories symlinked in /shared... Maybe there''s a way to extend the

I have a new @offer that needs to generate a document if saved. But that''s all or nothing: transaction do @offer.save! generate_document end # handle exceptions if needed If save! fails everything is fine, but if generate_document raises an exception @offer is left as a model with timestamps, id, which is not a new_record? anymore (though the database was
