similar to: Creating nested hash from nested active record results

I''m trying to write a helper method similar to attr_accessible but instead it will be used to whitelist which attributes are available for serialization (attr_serializable). My first attempt at this was to override serialized_hash and modify the :only option to include nothing but serializable attributes. I''m facing a problem when nested models are ''included''

I''ve found these two snippets of code useful and would love some feedback. first, .should_have_valid_associations usage: context "A new Product" do specify "should have valid associations" do @product.should_have_valid_associations end end code: (thanks to Wilson/Defiler for converting to rspec) module Spec module Expectations module Should

Hello, I have a question. I would like to know if there is a way with the reflection and respond_to? to know if there is a relationship between tables. When I say that I mean if inside a model there is a Has_many or belongs_to declaration. Because I try to get this information dynamically, during the execution of a script. If someone has an idea even if it''s not with the reflection,

I want to find out what are the associations with another active record class. So If my class is as below: Class Component < ActiveRecord::Base has_many :branches end class Branch < ActiveRecord::Base belongs_to :component end and then I do Component.reflections[:branches].active_record I would expect that to be Branch but it is in fact Component. The inspection of

So what i want to do is in my code loop through all the associations for a risk and display some field information from each as they are pretty similar. So somehting like <% for model_association in project.risks %>

I want to have popup menus and check boxes in my forms to let users select associated objects. In the form I''m working on, the object "belongs_to" another type of object which is selected from a popup menu. The id of the chosen object(s) for association is passed back in the parameter hash, but when rails creates a new object from this parameter hash, I get a

The first administrative console screencast is now available at: http://screencasts.visualjquery.com/demo1/ I''ve posted a bunch about the Admin Console, but it''s essentially an automated scaffold that works as an engine. The screencast is a quick overview of the minor things you''ll need to do in models, environment.rb, and others, as well as ::drumroll:: a demo of

Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>".

Hi, I''m trying to include the support of Msgpack<https://github.com/msgpack/msgpack-ruby> in Rails 3.2 but when I try to return a mpac response, I get an error concerning a missing template.

Hello people, I''d like to detect whether an attribute of a model has vaildates_presence_of applied to it so I can automatically apply a mandatory (*) to the field...it doesn''t look easy...any ideas? Cheers, -- Dan Webb http://www.danwebb.net

I''m trying to send to my application the coords x,y on an "input type image" in a html form, but x,y variables are not present in the POST_DATA (are not submitted).

I am assuming this an appropriate place to discuss this, but if it isn''t my apologies- just let me know. Just a Rails 4-ish thing. Am attempting to pull AMS (active_model_serializers), strong_parameters, and the "permitter" strategy that Adam Hawkins is using: http://broadcastingadam.com/2012/07/parameter_authorization_in_rails_apis/ Code so far is here (in the

Is there a reason why AM:S doesn''t support arbitrary keys to serialization? I can see a lot of uses cases where arbitrary keys could come handy. Right now, if one tries to do it, AM:S checks if the keys match a method of the model and raises exception if it can''t find any. class Client < ActiveRecordBase attr_accessible :name, :address, as: :creator include

Hi, Version: prototype 1.6.0 I''m using the $F function to get the value of a field. It works fine in FireFox, but IE 6 and 7 are reporting "object does not support his property or method" (translated from german). In IE debugger it hightlights the line 3485: --- return Form.Element.Serializers[method](element); --- I searched the web, but this problem seems to be quite unique
