Hi Is there any way to temporarily stop the updated_at field from being updated when a record is modified with ActiveRecord? I have a date field which is keeping track of when the record data was last checked by my application and my app manually updates it, of course when I do this the updated_at field is also touched making it fairly useless for finding out when the actual data was changed

This is for Rails 3.1.1 I have a field called last_seen in a model. This field will be updated when the something about the record is seen in the real world (don''t worry about this part) So I go x.update_attribute(:last_seen, Time.now) and the following happens is UPDATE "blah" SET "last_seen" = ''2012-10-23 08:57:46.179288'', "updated_at"

Hi.. Guys new plugin again Foreign Key Associations is a plugin that automatically creates associations based on foreign-keys. The associations are created at runtime-ie. as your ActiveRecord models are loaded-so they will always be up-to-date. For example, given a foreign-key from a customer_id column in an orders table to an id column in a customers table, the plugin creates:

Hi all! How can I change the name of the schema_migrations table? I have to do this because I can only use one database but want to have several rails projects.

Hi all! I have come into a strange issue in Rails that I am hoping someone can shed some light. To make a very long story short, I have been researching how to override ActiveRecord::Base#read_attribute and write_attribute to perform security checks at the model level (influenced by the ModelSecurity generator). Shortly after implementing some code to check this behavior, I began to

I''m using a legacy table, where the unique id is not ''id'' I have a Model class like the following: class Article < ActiveRecord::Base set_primary_key "ARTICLE_ID" end however, using a link_to like the following (modified scaffolding), the link has no id value: <% for article in @articles %> <tr> <% for column in

I am sending files from a 4.1.X SunOs machine to a Sun-Fire Solaris 8 with D-2 in an attempt to upgrade our systems. I moved 0ne f/s successfully containing ~ 450 M. I am now trying to move a file system of ~ 6 G. I get the output of make_list and expand file_list to 4000 bytes. It shows the moving of approx 4000 files but none are moved and the sending machine stops at the same file each

Hello I''ve been struggling with something for hours that I thought would be a simple job. Hopefully somebody can shed some light on what I''m trying to do :o) First of all I''ll explain what I''m trying to achieve. In a store application I want to have products and product variations. A product variation should inherit all of its properties from product unless

I have a database field called dates in which I am trying to serialize an array of DateTime objects. When I unserialize them, they are coming back in as Time objects. I know this, because I am getting errors that say "comparison between Time and DateTime failed. Why is this happening? Is there a way to prevent it??

I used the "serialize" class method on one of my models to save a hash in my database. It works fine, but now I would like an easy way to edit the hash with a form. I tried to make some googling, but I didn''t find anything about it. How is this done easily? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this

I defined in my model : ... serialize :unavailables .. which is set like this (Hash : "year" => 2-dimensional Array) {"2008" => Array.new(13).map!{ Array.new(32, 1)} } In my fixture I need to initiliaze this field with the following hash : {"2008" => Array.new(4).map!{ Array.new(32, 1)} + Array.new(1).map! { [1, -1, -1, -1, -1, -1, -1, -1, -1, -1,

Not really a solution, but this has to be a classic example of PHP- programmer-bass-ackwardness. They''re already writing to an extensible serialization format (XML) but then just whack language-specific serialized data in instead. That''s right up there with the HTTP-over- SOAP-over-HTTP stuff I''ve seen floating around... --Matt Jones On Sep 24, 9:14 am, Andy

Hi, I have a model with a serialized field ''other_data''. How can I add raw YAML data to that field?

Hi, I''m using the Builder gem to transform an array/hash that contains serialized ruby. Builder''s to_xs method seems to mangle serialized ruby though. I can get around this by encoding/decoding with base 64, but that doesn''t seem like a good path to follow. Builder is using this code for escaping: http://intertwingly.net/stories/2005/09/28/xchar.rb Any ideas on how to

Hi all, I''m trying to serialize a form with the exception of one specific element. Serializing the form in a hash (without pulling out specific elements) works: <li> <%= link_to_remote ''(Save)'', {:url => post_path(@post), :with => "$ (''post_form'').serialize(true)" }, :method => :put %> </li> The generated code

Hi, I would like to import a serialized object (from a JSON export) inside my database. It work fine if for instance I do: >> l = Yea.create(:title => "foo bar") => #<Yea id: 3, title: "foo bar", created_at: "2010-07-05 21:44:54", updated_at: "2010-07-05 21:44:54"> >> j = l.to_json =>

I have a few questions and thoughts regarding class versioning and serialized S4 class instances. How is the version argument to setClass is intended to work?
