In production mode, I keep getting this error the 2nd time it loads a page with a serialized attribute: ActiveRecord::SerializationTypeMismatch (answers_container was supposed to be a Array, but was a NilClass): /vendor/rails/activerecord/lib/active_record/base.rb:1964:in `unserialize_attribute'' In development, it works fine.

Hello, I have a freeze field in a table (that I can''t change).

I am dealing with a large project. I use a lot of STI and therfore have a lot of models. I''d like to use namespaces to help organize my models but am having trouble getting started.

Hi, I''m rather new to Ruby and RoR, so I do not really know whether this ist the right forum to place my question. For my first ''project'' I planned to create a simple online-viewer, which grabs data from an existing database and make them visible in a structured form via browsers. So I thought that could be the right beginner-project, because I have only read datasets

Trying to get an otherwise working app (in Rails 2.0.2) up to speed with Rails 2.1.0 and Ruby 1.8.7, I have some broken code I can''t seem to fix: module Pathmaker def self.append_features( base ) base.before_save do |model| model.path = model.name.downcase. gsub( /\ and\ /, ''-'' ). gsub( /\ on\ /, ''-'' ).

Hello. In one of my ActiveRecord models I specified a a serialize field: serialize :settings MyModelSettings If I understand the documentation correctly this restricts settings to the class MyModelSettings. The problem is that this is so restrictive that I even don''t know how to initialize the field. MyModel.new or even MyModel.new(:settings => MyModelSettings) everything I do

I was having this error in Development but not in Test: ActiveRecord::SerializationTypeMismatch: cambiable_attributes was supposed to be a Hash, but was a String Which was the problem? I was using MySQL in Development and SQLite3 in Test. Field ''cambiable_attributes'' was type String in the DB schema and had to be type Text. I changed the data type to Text and it worked well in

Hi Everyone, I''m totally brand new to RoR. I''m really starting to love coding more now that I''ve found RoR. I have what might be a dumb question, but I''m curious to know this. Is it normal to get this result: In the Beginning Rails 4 book I''m following this step: irb(main):097:0> article.location = "Toronto, ON" Here''s

Hi, For some reason, this harmless block of code in my application controller def index @wide = true end is causing this hideous error. I have read the error means that the error is raised when attribute has a name reserved by ActiveRecord. Does that mean that none of my models can have columns named "toggle"? Here is the error and framework trace:

A weird problem occurs (only on the prod server, not locally), when i try to register a new user with restful_authentication. Once in a while, i get the following error when trying to sign up as a new user: Insecure: can''t modify hash usr/lib/ruby/gems/1.8/gems/activerecord-2.2.2/lib/active_record/attribute_methods.rb:309:in `delete''

This SystemStackError is driving me crazy. It only takes place when testing with WEBrick - I can''t reproduce it with any tests. It is caused by calling the "missing" id method (base.rb:2435) on my ActiveRecord class. WEBrick and my tests are running as the same user, with a `ulimit -s` of 10240. Plus the query works sometimes so I don''t think this matters.

So I''m not exactly using Rails, but just ActiveRecord. Though I felt this would be more appropriate in the Rails forum than the general Ruby forum. I''m working on an app that interacts with databases, without having a database of its own. I have a class called Modeller, and a Modeller#retrieve_model(name) method that takes a name, looks for a table matching that name, creates a

I have the following: MODEL: def self.get_tag_cloud Rails.cache.fetch(''fetish_tag_cloud'', :expires_in => 1.hour) do find(:all, :conditions => [ "approved_for_tag_cloud = true"], :order => "LTRIM(name)") end end CONTROLLER: def index @fetishes = Fetish.get_tag_cloud end VIEW: .... <% @fetishes.each do |fetish| -%>

Hello I have been wrestling w/ the frozen hash problem in a script and I''m trying to catch this at the source where it crashes the program in flames. Unfortunately, when I look at the errors, the failure is way up in the active record ancestery chain. Here''s the first entries in the error output:

Hello, we are in troubles with smbd processes which are rapidly growing in terms of memory usage. We did implement a mean that gives us ability to dynamically mount or unmount samba shares. I prepared a simple script which demonstrates this very closely. Script loops following operations: - touch samba config file to make it newer - send SIGHUP to smbd process (kill -1 <smbd_pid>) -

Hey, I''m kinda desperate cause I''m getting an error and have no idea how to fix this since it doesn''t give me any information hinting where the problem is: irb(main):054:0> reload!;User.last.save! Reloading... NameError: undefined local variable or method `to_ary'' for #<User:0x4ed5d20> from
