similar to: save without commit ?

hello it seems like this question has appeared a few times with no answer: how do you get rails to issue ''write'' statements (ie ''CREATE/UPDATE'') to the database without committing each time? I tried setting ActiveRecord::Base.connection.begin_db_transaction before calling any action on my object, but as soon as myObject.save or myObject.update is called,

Hi has anyone managed to use update_all with rails on postgres? In my setup, it does not work: >> @keyword.update_all(myupdates) NoMethodError: undefined method `update_all'' for #<Keyword:0xb7ac4670> from /home/lib/ruby/gems/1.8/gems/activerecord-1.14.0/lib/active_record/base.rb:1786:in `method_missing'' from (irb):14 I checked that the base.rb

Hello I''ve now read a lot about application-level authentication in Rails, but I need to do database-level authentication. The reason is that my database needs to have the current_user (database current_user, not current_user defined in an ActiveRecord Model) set to execute triggers for automatically updating audit tables. So it is not enough to have a session check against a User

Hi All I wanted a little advice on the convention for namespace usage and organisation of code. I originally used PHP and often had an "admin" backend that performed the various admin tasks with users, and data Then I had a front-end often situated at the root that had user services. I''m trying to emulate this in Rails but feel I''m missing a significant point here and

Hi All, I''m trying to use a form to upload a photo that I will save using attachment_fu. I''m very new to Facebookr so I apologize if this is covered somewhere, but I''m kind of stumped. Here''s what I''m doing now: <% facebook_form_for(:my_object, :url => { :action => ''upload_photo'', :id => params[:id] }, :html => {

Hello How can I test equality with two objects when they include some attribute that is BigDecimal? if I make something like this: it "should ...whatever" do obj = Factory.create(:my_object) ... MyObject.first.should == obj end. FAILS This fails because the object expected is different from the object gotten, and the only difference are the BigDecimal attributes, that are

Not sure if this is possible currently. I have a section of code like this: ActiveRecord::Base.transaction do cow.save! duck.save! dog.save! end (Names changed to protect the innocent.) I''d like to specify that the saves run in a transaction. I can do ActiveRecord::Base.should_receive(:transaction).and_yield But is there any way to specify that the code is

What are the limitations on using: errors.add_to_base to display errors in views? I have tried for days to add errors from my object.rb and they never get displayed. class Keyword < ActiveRecord::Base validates_presence_of(:name, :message => "Name is required.") validates_uniqueness_of(:name, :message => "This name is already in use. Please try

I know ActiveRecord doesn''t support composite primary keys, but I need to use one, and I need it ASAP. I don''t need any composite foreign keys, luckily; what I have is a table that stores old versions of rows in another table, so the composite key is an id + date stamp. Would someone tell me a hack I can use to support this? -- View this message in context:

I didn''t get a chance to go to this meeting debating WebObjects Vs Rails, but here''s a report about it: http://desperatepundit.com/blog/cremes/technology/2006/02/15/WebObjects-versus-Ruby-On-Rails.html I don''t get what he''s saying, hand coding the model? yeah, you COULD ... but what about script/generate ??? And is that so what he said about security? --

Hi all, I am very new to Ruby and I have a silly question: how do I get RoR to "recognize" that I just defined a class? To be more explicit, I have a controller and view, and then I want to create a class and get the controller to "see" it. So, I created a file called "myobject.rb" in the models/ directory and inside it defined "class myobject [...] end".

Hi all - I know this must be really easy to do, but I can''t for the life of me figure it out. I have about 100,000 rows I need to migrate over into rails using a migration. Right now, I select all of them out of the old database and do a series of: ... new.col = old.col ... new.save ... Problem is each one is it''s own transaction. And it''s slow. I''d

Hi, We have 2 problems with rsync over ssh that we haven't been able to replicate all the time. Basically, we have a developement server running Solaris 2.5.1 and another running Solaris 2.6, the development tree is shared via nfs. When minor changes are made they are distibuted to various mirror sites via a perl script which does some checks (path, etc) and runs 'rsync -e ssh ....'

We have samba 2.0.0 running on Solaris 2.6 (Sparc) sharing out various directories and user homes. Recently I've set it up for Win98 logins and all this is working fine. Unfortunately this also means that if the server has to go down so do the clients, as we're pushing the users to use the server as much as possible. My question is what would be the best way to set up a Backup Samba

Hello! I experienced problems with testing transactions which are supposed to be rolled back, but are not, because of transactional fixtures eliminating the inner transaction. Can this be worked around somehow without turning off transactional fixtures? Maybe savepoints can help this? Does anyone have any experience with savepoints to achieve nested transaction functionality? Both Postgres

I need a single boolean which would be "globally" accessible to all instances of a class. Seems like the boolean should be in the class prototype, but I was troubled by the difficulty of setting the prototype boolean to true. Maybe I''m missing something? var MyObject = Class.create(); MyObject.prototype = { bSwitch: false, ... other methods and properties } var oMyOb1

I am working on a new package to do fire department analysis. I am working with emergency dispatch data from different agencies that all contain the same information but have slightly different formats. Typically the variable names and date-time formats are different. I am getting pretty good at reading in and rearranging the data so that it is essentially in the same format, but it is common

I have a mock object (Person) that is associated with another object (my_object) through a belongs_to association. When I check whether my_object is valid (my_object.should be_valid), I am getting an error like the following: Mock "Person_6338" received unexpected message :marked_for_destruction? with (no args) Checking the list of methods on the mock,

Hi everyone- Model.update_all works and changes the records, but it''s not changing the updated_at field. Am I doing something wrong or is this by design?
