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

Hi, Does anyone knows how to manage transactions in RoR. Thanx

Hi, I have a problem where I need an auto-incremented id back from the database for a statement that has yet to be committed. The operation that uses the id may fail, and if so, I need to rollback the database. I can''t figure out how to send only the statement to the database without the commit without sending over hard coded SQL. This is what I started out with: 1 def add_album

Hello, I have an application where I need to create two records in a database transaction. ie: begin User.transaction(user) do User_details.transaction(user_details) do user.save user_details.save end end end rescue flash[:notice] "Insert rolled back... but why..??" end >From reading the Agile book, I gather that once I wrap the

I read in various places that although migrations aren''t transactional, all you need to do is wrap you migration method in "ActiveRecord:: Base.connection.transaction do" to make the self.up or self.down transactional. In my experience (Rails + PostgreSQL), this doesn''t work very well. If my migration hits an exception, any tables that were touched remain modified.

PLEASE help me - this is making me insane. Can anyone suggest any reasons for this behavior? It occured previously, then went away and is now back. In Task.rb (where task is an active record subclass) def clear_schedule puts "clearing schedule for task" scheduled_end_date= nil #reset the scheduled end date save halt.

When I use stylesheet_link_tag, the results come back with a timestamp ID, like this: <link href="/stylesheets/style.css?1154009736" media="screen" rel="Stylesheet" type="text/css" /> I don''t want the query string and ID on the end, but I can''t see how to disable this in the docs. How do I do this? thanks, jeff -- Posted via

Hello, I have the following structure: model foo has_many :bars:, :dependent => true end model bar belongs_to :foo end In my action, when i try to save foo: def save begin f = foo.new f.a = 5 begin b = bar.new b.a = 10 f.bars << b rescue Exception => exc ... end f.save! <-- This does not happen

My flash object stays persistent even after I redirect to the next page. For example, I may set flash[:foo], then redirect to /bar, which successfully shows the flash[:foo] field. But if I then click on another page that also displays flash[:foo], it shows the same contents from the prior page. The flash[:foo] field persisted past the first page redirect. but I thought it was supposed to

I have a main form representing the model, let''s call that ''Order'', and a partial displaying its'' OrderLines. I use the bulk update methods to initialize model objects directly from form data, leaving validation of business logic to the model. As AR likes to write stuff before i do an explicit save, I wrap the whole update in a manual transaction. This works

I cant seem to find much information apart from the basics on transactions in rails. I have 5 nested transactions, and am performing the following basic operations: @whatever1.transaction do @whatever2.transaction do .... @whatever2.something = "foo" @whatever1.something = "bar" @whatever1.save @whatever2.save ..... end end ((( I had tried using

Hello, R 2.3.0 Windows XP I have spent quite a bit of time trying to resolve my problem below, which included a R site search.

A short while ago I reported a network interruption while performing a YUM update on a server. A check of the logs as recommended by a list member indicated that the update process had succeeded. However, I am now encountering the following problem on that same server and my nastily suspicious mind is trying to tell me that the previous event and this situation are somehow related. >

Seems currently xenstore transaction provides confusing message in different places: a) comment of xs_transaction_start says "You can only have one transaction at any time." However do_transaction_start allows up to 10 transactions created, as long as all other existing transaction channel is idle at the time (conn->transaction == NULL) b) when multiple transactions can be

Hi, I have some blocked transactions. Does anybody have some advise on how I could mend this because I am unsure where to start? I believe this broke after I issued some set auth.allow commands: # gluster volume set oem-shared auth.allow 10.54.54.57,10.54.54.160,10.54.54.161,10.54.54.213,10.54.54.214,10.22.9.73,10.22.9.74 Kind regards, Sophie [2017-06-20 13:28:24.052623] E

I am developing a large scale financial application which is going to be very intensive write-wise, and use a lot of transactions. I can see how the the web and application servers can be scaled and load balanced quite easily, but not the database tier. The setups I have looked at so far seem to deal with coping with a lot of reads, and minimal writes - this maybe because they are largely
