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 new @offer that needs to generate a document if saved. But that''s all or nothing: transaction do @offer.save! generate_document end # handle exceptions if needed If save! fails everything is fine, but if generate_document raises an exception @offer is left as a model with timestamps, id, which is not a new_record? anymore (though the database was

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?

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, I just wanted to update my Rails installation with "sudo gem update rails" but I get this error: Updating installed gems...

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

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. The test database is configured as: test: adapter: sqlite3 database: ":memory:" and I get this error with the simple product test: % ruby test/unit/product_test.rb Loaded suite test/unit/product_test Started E/usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.1.0/lib/sqlite3/ errors.rb:94:in

Hi, I have a User model, with a validates_uniqueness_of :login The generated SQL for the validation is: SELECT * FROM `users` WHERE (LOWER(users.login) = ''fernando'' AND users.id <> 10001) LIMIT 1; and it takes 0.13s to happen (my table has 10.000 rows) When I use the EXPLAIN instruction on it, it shows that it will use the primary_key as index, but this is not

I have an error I don''t know how to debug. I am adding the login suport in Depot (the example in the RoR book) and LoginController#add_user throws ActiveRecord::StatementInvalid in an innocent /login/add_user GET request. The trace goes down to a call to SQLiteAdapter#table_structure, and the source code suggests what''s happening is that "PRAGMA

Before the new db tasks I used as anyone a custom task. It used IO.popen("mysql -u root -p", ''w'') to pipe SQL based on ActiveRecord::Base.configurations[RAILS_ENV]. The new db tasks assume the configured user can create and drop databases. Do you people actually grant those privileges? -- fxn --~--~---------~--~----~------------~-------~--~----~ You received
