...tween create and create! I see that create is document in the api http://api.rubyonrails.org/classes/ActiveRecord/Base.html#M002269 What is the difference between the two of these functions and where is the create! function defined. Also, What are the differences between these two calls? a) SomeModel.create!{ :property_a => ''value'', :property_b => ''value 2'' } b) SomeModel.create!({ :property_a => ''value'', :property_b => ''value 2'' }) Thanks a lot for the help! -Jim --~--~---------~--~----~------------~------...

I have a question regarding best practices around module and plugin testing for rails applications. In our application we have created several plugins that extend ActiveRecord::Base with class methods, that when invoked in a model add behavior to that model. For example ... class SomeModel < ActiveRecord::Base adds_some_cool_behavior adds_another_wicked_sweet_behavior end My initial thoughts are that any model that add these behaviors "should" have this specified in their spec. With that in mind, I was leaning towards creating a module that when included inside...

I have a simple question when to the synchronize method in the Mutex class. Now that backgroundrb has allow_concurrency = true there is no need to synchronize database calls in threads. The question I have is lets say I have a simple method in my worker as follows: def some_method SomeModel.find_all each do |obj| obj.some_count += 1 obj.save! end end It accesses the database, but is not in a thread. Since this is a single process running in the background, if that method gets called simultaneously will the database lose connection? Will I get unexpected results? For instan...

Hello, This is probably a silly question but looking at "api.rubyonrails.org", I can''t seem to figure out which method I should be using ... I want to execute an sql statement, like "truncate table BLAH" from within one of my rails app ... What''s the "right" way to do this? Thanks, /B -- Bruno Mattarollo <bruno.mattarollo@gmail.com>

Is there any scalable alternative to iterating all the records of a certain model? #find_all seems to load everything into memory. With 500.000 records it will be a swap storm. Pedro.

Hello, I need to access an mirrored database with one read and one write cluster. Is there a way to tell a model to use two connections? So that all updates etc go to the write database and all read from the read one? This is a fixed set up I can not use MySQL 5.x stuff and additionally i get a token on write, which can be checked on read (and wait for replication) if new data is needed. I

...a controller and then access it from within a view. It seems that the class variables aren''t working right.

Would it make sense for rake db:migrate to support creating databases if it is not found, with blessing from user to prevent typos, or as an additional command line switch. Or am I just being too lazy? -- Posted via http://www.ruby-forum.com/.

Hey, I have got a script that returns a long list of font family names, which I all want to store in a variable (array).

Hi, I am writing an active record adapter for our new database and when I run the tests I see lots of statements that could be run as prepared statements, but instead of passing me bindings AR passes me a fully specialized SQL string, not in all cases, but in many.
