similar to: Acts as nested - Enforcing a Max Level

Hello, I''m using the Awesome Nested Set plugin: https://github.com/collectiveidea/awesome_nested_set And in my model I do the following: acts_as_nested_set after_save :ensure_max_nestedset_level private def ensure_max_nestedset_level if self.level > 2 self.move_to_child_of(parent.parent) end end I do this to keep the levels from getting

Hi Railers, Is the nested set model restricted to only one root? I''m working on a screencast building a threaded forum and nested set comes close but is lacking a few items for this project. First, all the documentation I can find restricts a nested_set to one root node, and a threaded forum would have many roots. Also, without a ton of fancy sql or an ungodly amount of db calls, it

Hi I was wondering if acts_as_nested_set can be used safely with concurrently updates? The fact that so much of the tree needs to be rewritten on inserts concerns me. Is anyone actually using it. I noticed that the status of acts_as_nested_set was unclear at the time the rails book was written. Regards, Glen

Hi, I have a scenario where a doctor can have one or more specialties. For each doctor, one and only one of her specialties can be designated as primary. So I have tables called doctors, specialties, and doctors_specialties, the last of which has a boolean is_primary column. The doctor model class specifies that: has_and_belongs_to_many :specialties I want to enforce, at the lowest possible

I have a user model and a status model. Each user has a specific status (accepted, rejected, declined, etc). I have a form that allows the adminstrator to change certain options for a user, including their status. I''m using a drop down menu populated with the different status values, and a default option that says "Choose a new status" with a value of "". I want to

I''m trying to enhance acts_as_nested_set. Well actually I already have, but I''ve done a hack up job of it. I would like to contribute these enhancements back, but I need a little help. I''m a complete newbie to this stuff. The only thing I new before coming into this project was vanilla HTML. So over the course of two weeks I''ve picked up Ruby, Rails, MySQL,

Hello, I have a table of zipcodes that I am using in my application, so there are approximately 50,000 rows in this table. I have dumped the table to a fixture yaml file to represent this data, but when I try to load it, I get this error: SystemStackError: stack level too deep Is there a max size allowed for a fixture file..?

I am having a problem finding the best way to make a "before_save :encrypt_password" conditional. I have to at times update user model attributes but each time I do this the password is reencrypted because of the above. I need to differentiate between when the user is first logging in and the password does need to be encrypted, and when they are already logged in and the

Is it will known and accepted that before_save triggers should return true? I didn''t notice this before but now I see it in the documentation. Here is what I''m doing in my model: def before_save if self.has_album? self.visible = self.album.visible? end end That results in the expected result when album.visible? is true - but not when it is false. To make it

Yay, another Task model: ## the model class Task < ActiveRecord::Base attr_accessible :lots, :of, :stuff, :but, :not, :finished_at, :and, :finished before_save do @before_save.call if @before_save end def finish self.finished = true @before_save = proc { self.finished_at = Time.now } end end ## usage t = Task.find(some_id) t.finish t.save (same code on pastie:

Hello I''m looking to learn how to redirect all non-www (mysite.com) to https://www.mysite.com I tried the following: class ApplicationController < ActionController::Base before_filter :check_uri def check_uri redirect_to request.protocol + "www." + request.host_with_port + request.request_uri if !/^www/.match(request.host) if Rails.env ==

Is there a way to get the MIME extension of a file_column field? Here''s what I want to do (look for comment in before_save method): class ProductFile < ActiveRecord::Base belongs_to :product file_column :file_name def before_save self.file_type = # something that returns the MIME type (e.g. image/jpeg) end end TIA

I''m using Restful Authentication, and the code to create a user is pretty straight forward - there is a before_save action and a before_create action: before_save :encrypt_password before_create :make_activation_code But for some reason when I try to create a user programmatically in the controller like this: User.new(:email =>

Hi there I''ve been running BackgroundRb in production for a few months now. Recently we added encryption onto some of our ActiveRecord fields by hooking in the before_save and after_save callbacks, like: class MyCallback def initialize(attr_names) @attr_names = attr_names end def before_save(model) @attr_names.each do |attr_name| next if

Greetings, This, I hope, is a simply answered question. Based on Agile Web Development with Rails (depot application), I''m developing a single table application for contact info. There is only an admin side to this, so there''s always authentication. Part of the info record (member) is changed_by and changed_at which I automatically want updated. Changed_at looks after

I have a callback (before_save) that I want to trigger only when certain fields within a record have changed. For example given a user record with ''username'', ''password'' and ''date_of_birth'' I would like the callback to do something only when the ''username'' or ''password'' changes or when the

Hi, I am having difficulties accessing parent properties/attributes from the child. Anyone could shed some lights onto this? Heres a sample code: class Parent < ActiveRecord::Base :has_many => :childs @connector def before_save @connector = ''some connector object'' 0..9.do |count| self.childs << Child.new self.childs[count].connector =

There''s a small inconsistency in ActiveRecord''s callback syntax that has tripped me up before. It wouldn''t be a big deal, but it can lead to a silent failure. I''d like to suggest that it either be made consistent or be made to fail loudly. The issue is that to do something before validating, but only when creating, you use `before_validation on: :create`,
