Hello all, I am working on a app right now that is going to replace a paper form process out client has. This process has quite a few forms (about 30) and different groups of forms (section) need to be filled out based on what information is required from the user.

Hi I''m struggling to find a neat way to spec this. The Sequel ORM doesn''t support automatically destroying dependent models. It''s easy enough to do in a callback though: class Changeset < Sequel::Model has_many :migrations, :class => DataModel::Migration before_destroy do migrations.each { |m| m.destroy } end # ... end

I wanted to group some functions which I use in some models in one place. Controllers have application.rb and views have helpers but I couldn''t find anything about models. Using the /lib directory seemed to be the only way. Alright... so I have something like this: /lib/code.rb class ActiveRecord::Base def method_a(n) ....... end def method_b(n) ........ end end

I have a problem with before_destroy deleting by dependent records, even through I return flase. ... has_many :users, :class_name => ''Editor'', :as => :editable, :dependent => :destroy ... def before_destroy unless self.has_access?(99) errors.add_to_base "Destroy permissions error!" return false end end When I remove the dependent

Hello- With a database filled with several customers'' datasets, I thought it would be a nice feature of my app''s backend interface to be able to extract (and optionally delete) the data from a single customer. It would then also be nice to rebuild that data from the stored info. What''s a good way to do this efficiently? If all the ":dependent => true"

According to the documentation, if I return false in a model''s before_destroy method then it should cancel the action. Although I know it is reaching and running this code, it deletes the object despite the "return false". I''m sure this were a bug it would have been noticed by now so I must be missing something but I cannot imagine what. Even in the simplest

Hey, probably an easy question but, I''m trying to get a method to run "before_destory" for a model, and I want the method to throw an error, and not delete the object from the database, if a certain condition is held Obviously, I can just raise an error and rescue it... but for some reason I can''t get <% error_messages_for ''model" %> to catch

What''s the best way to validate_on_destroy. Rails only seems to include validate_on_create and validate_on_update methods. I don''t want to resort to doing: before_destroy do |j| raise "There is an error" if j.etc end Is there a way of finding out what action (create/update/destroy) is being performed if I use the ''validate'' method? -- Posted via

Rails has many built in validation methods to ensure that an ActiveRecord instance cannot be created or updated under certain situations (typically caused by invalid data). However, I can find no methods to govern whether an ActiveRecord instance can be destroyed. Essentially, I wish an error to be raised when a user tries to delete an ActiveRecord without first adhering to a certain set of

What''s the best way to exclude ActiveRecord in Rails3? In Rails2, one could just do: *config.frameworks -= [ :active_record ]* in the configuration block in environment.rb. Is it possible in Rails3?

Hi, There is something I don''t understand about :dependent => :destroy. I hope someone can help me. Consider this code: class Folder < ActiveRecord::Base has_many :myfiles has_many :folders has_many :group_folders, :dependent => :destroy validates_uniqueness_of :name, :scope => "folder_id" validates_presence_of :name before_destroy

Hi all I''ve approached Rails since a couple of months to develop a quick application for my company. Fantastic framework. As every noob, I do have some gaps to cover. The one which is giving me a little frustration, generated by my lack of knowledge is as follows. I need to make sure the region object is not deleted if there are countries associated with it. I solved this by putting a

How would I set up a model stub so that <%= error_messages_for ''some_model'' %> doesn''t complain? I started going down this road: @some_model.stub! (:errors).and_return(ActiveRecord::Errors.new) but it seems like a long, hopefully uneccessary road. Cheers, Michael
