similar to: recording updates

I have this situation where in an after_update, I would like to know the previous value of the record instead of simply being notified the record has been updated. For example let''s say I had a table called ''foo'' which had a field ''new_flag''. I want to know when the ''new_flag'' field changes from 0 -- > 1 in an after_update so I

Is there a ''replace'' method or similar for attchment_fu? For instance, I have an image that is uploaded and stored. Now I want to replace it with a different image. I do not want to do a delete and then new - since I need to keep various attributes associated with the previous image. thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message

I need to implement multiple undo functionality into a Rails app (my first one). Essentially, every .update and .save needs to record the previous data set and save them in a history table along with some identifying stamps, so each db action can be rolled back at any time. From what i can tell, i could implement this manually using observers perhaps; but this is Rails, so i wonder if

I''ve installed the acts_as_versioned gem, and it shows up as installed when i do a "gem list" After installing it, I set up my new model with the "acts_as_versioned" line in its model file. I think went to run my migration to create this table, and I got the following error: == CreateDpslevels: migrating ================================================ --

Hey guys and gals, I have the following object that has acts_as_versioned: class Note < ActiveRecord::Base acts_as_versioned belongs_to :user end The schema for my notes table is as follows: create_table :notes, :force => true do |t| t.column :id, :integer t.column :noteshare_id, :integer t.column :user_id, :integer t.column :title, :string

Hi All, Rails newbie here trying to set up acts_as_versioned according to Chapter 14 in the Rails Recipies book. I''ve taken the following steps (nearly verbatim) as mentioned by the book: - created the target model "Post" - added the "acts_as_versioned" label to the model file - generated a migration file - added the table creation code and the command

Hi all, Despite switching to mod_fcgid (which has improved performance), sessions are still expiring sporadically. I thought I might try switching to storing them in the db, but I get the following error when I try to run the rake create_sessions_table command D:\User\Code\ruby\prometheus>rake create_sessions_table (in D:/User/Code/ruby/prometheus) rake aborted! undefined local variable or

Hi people I have tried to install the acts_as_versioned gem from github in rails 2.2.2 but it seems to conflict with some methods in the activerecords dirty.rb-file. I can solve some of the problem by changing code in the activerecord, but I don''t think that was the intention. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to

Greetings! I''m attempting to use the act_as_versioned plugin to provide versioning functionality for my rails app, but can''t think my way through this: How can you use act_as_versioned to perform versioning on a HABTM join table? It is easy to see how to do so for join models (:has_many :through) but not so for the join table. I want to use act_as_versioned to maintain

I am looking at using acts_as_versioned to manage revisions of data in several tables in my application. However, the default behavior of acts_as_versioned appears to apply to individual rows within a table. The tables I want to version are complicated lookup tables and what I really want is to version the entire contents of each table as a single set. Adding a row, deleting a row, or updating

Hi, I am having trouble with using the acts_as_versioned plugin. I installed the plugin, and ran the migration. acts_as_versioned created the versioned table OK, but when I try to use it I get an error. Here is some console output: >> m = Mymodel.find(:first) NameError: undefined local variable or method `acts_as_versioned'' for Mymodel:Class Did I miss a step? Ingo --

I am trying to use acts_as_versioned and acts_as_taggable (plugin) on the exact same model. Has anyone successfuly done this? I think what I need to do is make model_versions acts_as_taggable instead of my main model. Anyone have any other suggestions or any suggestions how to do this?

Hi, I'm integrating acts_as_versioned (ar-versioned.rubyforge.org) in my customized CMS rails application to set up revision control for pages. Getting and viewing versions works allright, but when I try to revert to a version in the following way, nothing happens to the actual data in the object. Link from page: <%= link_to image_tag('revert'), :action => 'do_revert',

Hi, I seem to remember seeing the equivalent of saving only if all attributes are different. I can''t seem to find that now in the API or the agile book. I''m using the acts_as_versioned and only want to save if the input is different. Thanks, Steve http://www.smarkets.net -------------- next part -------------- An HTML attachment was scrubbed...

I am very new to Asterisk, it was a weekend project of mine that I jumped into this weekend. I have it up and working on a box at home, and I am nearly half way through the book I purchased friday "Asterisk: The Future of Telephony 2nd Edition". Anyway, I started this out so I could help a friend who wanted a VoIP PBX solution for his small business. I have been working with Cisco

Hi list, I''ve got some counter_caches in a model. When these get incremented - say on a page view - my updated_on column also gets updated. How can I conditionally not update updated_on if just these counter_cache columns change? The problem with that is that I am using acts_as_versioned which clones the record each time updated_on changes. I am successfully ignoring the counter_cache

I've written a function that takes some input data output from a simulation model and creates some graphs. It's not very complicated code, and it works perfectly fine if I just run the code as is. But I have converted it into a function so we call it externally, and when I try to source the code to test the function, I get the error message "variable names are limited to 256

I am wondering what is the best way to mock such expression: "comment.initiator.group.name" What I do now is: =========================== comment = mock_model(Comment) initiator = mock_model(User) group = mock_model(Group, :name => "Admin") initiator.stub!(:group).and_return(group) comment.stub!(:initiator).and_return(initiator) =========================== So it becomes

Hi all, I am not sure how to handle interactions with categorical predictors in the GAM models. For example what is the different between these bellow two models. Tests are indicating that they are different but their predictions are essentially the same. Thanks a bunch, > gam.1 <- gam(mortality.under.2~ maternal_age_c+ I(maternal_age_c^2)+ + s(birth_year,by=wealth) + +
