similar to: populating model attribute from one of many lists

Hi all I tried and tried and tried, but I still fail in creating a form with proper validation and stuff for foreign keys... So I''d really like to get some help here. I''m creating a booking site for DJ''s, and for every booking one can choose one of different countries: class Booking < ActiveRecord::Base validates_presence_of :country_id

Disclaimer: RoR newbie. Using the acts_as_taggable plugin. As an exercise I wanted to switch from the destructive TAG_WITH method to adding tags while preserving the existing ones. On the surface this seemed easy enough and eventually I got it working. However, the following method: def add_tags(list) Tag.transaction do Tag.parse(list).each do |name| if

I''ve installed the acts_as_taggable plugin and modifed it according to the tutorial form making it user specific (http://www.slashdotdash.net/blog/articles/2006/04/29/acts_as_taggable-per-user-tagging ). I keep getting errors when I try to tag things, however, and have traced the problem to the line of the tag_with function that calls the find_or_create_by_name function. So I fired

Hi everyone, I''m refreshing the local Rails database from a remote database every 10 minutes. I''m using a :through association to relate people to mailinglists through subscriptions. # Works fine, every 10 minutes: remote_lists.each { |list| List.find_or_create_by_name(list.name) } remote_subscribers.each do |subscriber| person = Person.find_by_email(subscriber.user)

Hi, I was looking around a bit and couldn''t find any callbacks that executed before before_validation The current problem with using before_validation is that it won''t fire if I''m not using validations with #save(:validate => false) - which makes sense. Before_save won''t suffice because I want these callbacks to fire before validation on the occasions that

Hi all ! I''m having an issue and I can''t seem to make heads or tails of it. I am attempting to add an observer to a model object. I created app/models/greenback_transaction_observer.rb, inherited from AR::Observer, defined methods, registered in config/environment.rb, but things don''t work... So, I took a step back and put in the following code: class

Hi, There is a line in acts_as_taggable plugin: send(acts_as_taggable_options[:from]).tags.find_or_create_by_name(name).on(self) could someone explain what is: send(xxx) and .on(self) I cannot find it rDoc -- Posted via http://www.ruby-forum.com/.

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`,

This code: <p> <label for="resource_type">Type</label><br/> <%= select(:resource, :type, %w{ Web Data }, { :include_blank => true }) %> </p> Produces this error: TypeError in Resources#new Showing app/views/resources/_form.rhtml where line #6 raised: wrong argument type String (expected Module) Extracted source (around line

Hi all, After working on my first rails app and having handed over some very sophisticated coding from a lot of you guys. My app does what I want it to do, but I''m no where near the end yet, and it seems that the KISS and DRY objectives already went down the drain. It could be lack of knowledge, only doing Ruby on (and) Rails for a month, but I''m stuck on the following:

Hi all, I''m happily using "HowToReuseEditViewsForNewViews" found at: http://wiki.rubyonrails.com/rails/pages/HowToReuseEditViewsForNewViews There''s this comment there saying you only need the tag "<%= auto_form %>" when using the code below. Can somebody tell me if that will work when extending it with model_name (some how)? I have several new_*

Hi -- I''ve got a very strange error. I have an action called ''commit_input'' on a controller called ''SiteVisitController''. This definately exists, and is called from the functional test for it, and passes fine. My problem is with the form that is supposed to call this action. The form tag is: <%=

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

Can''t seem to find an example of this anywhere - how do I populate a select list in a form from a database? I have a form to create a new task. The task is for a client, so there should be a select list populated from my clients table. I thought this would work: <%= select ''task'', ''client_id'', Client.find_all, "id", "name"

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:

Guys, I''m using select_tag to display a non-model dropdown, which works fine. However, I''ve tried every which way to use the :include_blank => true option, but it simply won''t display a blank value. Using :include_blank => true with select on model fields works fine. Can someone please show me a working example? -- Posted via http://www.ruby-forum.com/.

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
