In Depot, the demo application in the the Agile book, actions that modify the model such as add_to_cart redirect to another action that has a clear view role, like index, or show_cart, instead of generating the view themselves. This uses an HTTP redirect that goes to the client and returns. Is this an idiomatic way to design the flow in Rails? -- fxn

I have a bunch of queries to compute some counters, like find_by_sql(<<-SQL SELECT p.*, c.nfavourites FROM people p, ( SELECT fp.person_id, COUNT(fp.user_id) as nfavourites FROM favourite_people fp, users u WHERE fp.user_id = u.id AND u.cluster = ''#{in_cluster_of_user.cluster}'' GROUP BY fp.person_id ) as c WHERE

I left ":memory:" in database.yml for testing and the most simple tests in the Agile book do not work (see trace below for test_truth). Since that''s what comes with the distributed database.yml I suppose it''s me doing something wrong. Did someone get SQLite ":memory:" working? How does it grab the schema? -- fxn % rake test_units (in

Hi, im looking to build a page similar to a shopping cart page. When you change the ''price'' or ''quantity'' fields, the total is calculated and displayed. There are other fields in the form which have no relation to this action. So i guess observe_form is not required. Can someone tell me what the best practise is for this?

So after successfully getting the test SQLite db to run from memory, I tried running some tests but found that somewhere in the schema translation from Postgres (my devel database) and SQLite Rails fails to properly set the ''id'' column, which breaks all kinds of things. Take as an example my ''users'' table. In Postgres the schema is (generated with pgAdmin III):

I have an model Order and a model Customer. Each customer has_many Orders. Each Order belongs_to a Customer. If I create an order but don''t specify a Customer (for whatever reason, maybe it''s unknown at the time).. I obviously can''t access @order.customer.name because I''ll get a nil error... So what''s the right way to handle that? If the Customer is

Howdy, I''ve been getting this issue for about a month in dashboard. All our nodes poll on a cronjob between 00:00 and 01:00 daily, but one node has been getting this as a failed task for a while, with the yaml files building up on the server. Outside of this one cronjob, other puppet runs on the same node are running just fine. The backtrace on dashboard is: Importing report

The new rescue_from in edge rails seems to conflict with ActionWebService, which I need for various other purposes. When I define, for example (with AWS gem installed): <b>rescue_from ActionController::RoutingError, :with => :page_not_found</b> I get the exception: <b>uninitialized constant ActionWebService::Dispatcher::ActionController::Base</b> OK, so AWS

I am following the rails book, and arrived to the section about testing.

I want to write a function that after an ActiveRecord saves successfully, can show me what the before and after values of a particular column are. Is this possible without creating a separate object before modifying the current one? -John

I have a pretty complex form with many text fields and a number of selects. We let the user add multiple types of associated objects to the parent object and to edit the values for those associated objs, so the form can have something like the following number of fields on the page: 9 text fields + 3 selects + a*(1 text + 1 select) + b*(1 text + 1 select) + c*(1 text + 1 select) + d*(1 text +

I am pondering the possibility of encrypting/decrypting some fields in a SQLite backend on-the-fly. The point of the message is not security, I know that''s broken, but whether there''s a technique that provides on-the-fly save/read filters. Of course the solution would need to work transparently in joins, so user.posts.last.title would do the right thing if title

I''ve got a model Message, which needs to send an email using action mailer after it''s first saved in the database. I want to pass the model to the mailer which then uses methods on the message model to render the email. So the natural way to do this is in an after_create callback on the Message model. But I can''t see an easy way to test this. Here''s my spec

I have been working through an upgrade of my 1.2.6 application to 2.2.2. I am almost there but I have hit a problem with ActiveRecord. Before the upgrade, the following code was working fine. def create_root(administrator) root = create_root_collection(self.pingee_name, administrator,
