similar to: polymorphic validation

Hi Everyone, Ran into an interesting case last night, and I was hoping that someone on the list here could give me some guidance. I''ve got a Polymorphic association for Addresses (which can belong to two different models). The catch is, one model requires a strict, precise address, and the other only requires a City, State and Postal Code. I want to use :validates_presence_of :street,

What are the limitations on using: errors.add_to_base to display errors in views? I have tried for days to add errors from my object.rb and they never get displayed. class Keyword < ActiveRecord::Base validates_presence_of(:name, :message => "Name is required.") validates_uniqueness_of(:name, :message => "This name is already in use. Please try

Dear R-sians.. I am trying to plot boxplots with side-by-side option.. I tried some of the posted suggestions and could not make it work due to unequal sizes of categories... e.g. weekly measured water depth values are categorized into 5 levels based on their values such measurement is again categorized into dichotomous levels - based on the result of a test I would like generate boxplot of

For example, in the following block: page.select(''.foo'').each do |element| ... end How would I access, just for example, the id attribute of each element in the collection? I''ve randomly tried element.id and element.attributes[''id''], but neither of those has worked. I''ve also been unsuccessful in finding any documentation on this, but it

Hello, I'm using the following Dial command syntax: Dial*(SIP/peer/exten!sip:xyz at xyz.com <sip%3Axyz at xyz.com>*), the SIP URI after the '!' mark should be set as To-URI in outgoing INVITE from Asterisk. It works, but problem is that To-URI formatting is a bit messed up, It looks as follows: *sip:sip:xyz at xyz.com <sip%3Asip%3Axyz at xyz.com>*, it seems that Asterisk

It seems to me that ipsecnat tunnel type is not complete. Latest drafts of ipsec nat-traversal use udp port 4500 for nat-traversal communications. (It''s called port floating). That is needed to get rid of ugly ipsec passthru devices. Now ipsecnat opens port udp/500 from any source port. And I think ipsecnat won''t work at all with gw zone defined? I''m not sure about

I have two partials to deal with contact information. The Contact information uses single-table polymorphism. I want to be able to use save on Contact and set ''type'' manually, based on the type of form the user is filling in. This is saved as the value on a hidden field. class Contact belongs_to :person acts_as_list :scope => :person validates_presence_of :type

Please help, I am really at a loss at how validation is supposed to work in rails. Model contains acts_as_tree I want to force my NEW objects to have a parent I do NOT want existing object to have a parent so I only want to have parent_id on create, NOT on update. I am trying this: def validate_on_create validates_presence_of :parent_id, :message => "You must specify a

problem: validation error is not functionning in callback callback for many-to-many association: # keyword.rb :before_add => :reject_self_related def reject_self_related(related_keyword) if (related_keyword == self) # this does not work: errors.add(:name, "Relating a keyword to itself is forbidden!") raise "Relating a keyword to itself is

Category.has_many :products Let''s say a product must belong to a category. I know it is recommended to do the following: class Product validates_presence_of :category_id end But, as we all know, this is a pain for new records, meaning what if the associated category is a new record? I''ve been meaning to ask this, but what''s wrong with doing the following: class

Hi all, I am a newbie to Rails. Please enlighten me on how to do this appropriately, the Rails and the Ruby way: Suppose I have a Recipe model. Let''s simplify things and pretend that it has only 2 attributes, a :name and the other is a ''category_id''. In the recipes table, category_id is a foreign key to field id of table categories. We also assume that I have generate

Is there a package in R that can do a variability plot? A variability plot is a kind of categorized dot plot. (If there is a lot of data in each category, box plots are used rather than dot plots.) Usually, the categories are factor level combinations. All the dot plots appear in the same window; below the x-axis a hierarchy of factors shows which dot plot corresponds to which factor-level

Is there an easy way to validate that a related record exists? I''ve got a table that contains a set of categories and I want to make sure the user has entered a vaild category (i.e. a category that exists in the categories table). So in the model of the table I put this: class Master < ActiveRecord::Base belongs_to :category, :foreign_key => "categoryid"

Hi. I have two tables and want to join them. <genres> id genre_name genre_order <links> id genre_id name symbol url order display etc The code of links_Controller is like below. def list @links = Genre.find(:all,:include => :link) end Below is the mysql log. SELECT genres.`id` AS t0_r0, genres.`genre_n ame` AS t0_r1, genres.`genre_order` AS t0_r2, links.`id` AS t1_r0,

Hi, seem to keep running into a wall here. I can''t find any resources on site navigation that can deal with any model being in the nav, allow nesting, and can dynamically update. So I thought about it for a while, and decided on a MenuItems class, which contained the position of the child in relation to it''s siblings, where the parent and the child were polymorphic. Then a given

I have a form with 3 fields: user_id, email and password. All 3 fields are required, so I have a "validates_presence_of :user_id, :email, :password" in my model. Works, but the validation errors show up in a different order than I specificed in the validates_presence_of statement. Is there a way to specify the order in which the validations (and corresponding error messages) should

HEllo, I have the following problem with rails, I am new in this...is there anyone who explain to me what´s happens? Thanks See below: NoMethodError in Classified#show Showing app/views/classified/show.rhtml where line #17 raised: undefined method `updated_at'' for #<Classified:0x686c5e4> Extracted source (around line #17): 14: 15: <strong>Date Posted:</strong>

OK - I know this has been asked before, but I cannot find it in the archives. Forgive me if I''m creating more noise than I should. I want to know the easiest way to deal with this scenario: I have articles. I have categories for the articles. On the form where you write an article, there needs to be a free-form field to entire the category. The create() method will build the

I want to use mocks and stubs to test the controller, but am having trouble getting my validation not to trigger. Here''s the code: # spec: Image.stub!(:find).and_return(@image) @image.should_receive(:save!).once.with(:any_args) put :update, :id => @image.id, :category_id => @category.id, :image => {:name => ''test'', :image_number =>

Looking over the contents of various packages, including my own, it is clear that lots of things end up 'hidden away' in packages where they don't belong. My gregmisc package is a particularly egregious example, containing something from almost every functional category. I propose that from time to time the R community go through the complete set of packages and 'refactor'
