I have been trying to use rails as the backend for sproutcore. I am following the tutorial: http://blog.lawrencepit.com/2008/07/19/sproutcore-rails/#comment-4 I have followed all the steps in the tutorial. When I try to run the http://localhost:4020/contacts, its gives me the following console errors: Contacts is not defined [Break on this error] Contacts.detailController =

I have been trying to connect to MySQL thru rails. Initially I had rails 2.1.2 and upgraded to rails 2.2 to use RestAPI in sproutcore. Once I have upgraded my rails version to 2.2, I have been getting this error. All I did is the following: 1. rails addressbook 2. cd addressbook 3. script/generate scaffold Contact first_name:string lastname:string 4. rake db:migrate I also change the

I''ve upgraded to 0.11 this morning specifically to test out the pagination stuff. When that didn''t work (didn''t recognise the command) I deleted my project and recreated from scratch. So in short rails projectname cd projectname edit config/database.yml (my database is postgres by the way) ruby scripts/generate model Recordtype ruby

Hi, I have two processes spinning up independent sets of guests, letting the guests run for a while, and tearing them down. The two processes are generally giving their set of guests a different "run-period", so the guest spin-up/tear-down will happen during different cycles/phases. Call these processes A and B, each is currently managing 32 guests. I am seeing an issue, where when

Hi all I''m creating a shop page. I have a cart model that looks like the following: class Cart attr_reader :line_items def get_line_item id @line_items.each do |l| return l if l.id == id end end def initialize @line_items = [] end def empty! initialize end def empty? return true if @line_items.empty? false end end And I have some

Hi there, Why are the instantiated fixtures turned off by default in the rspec on rails plugin? This was not the case in older versions. After upgrading (and much head scratching) I had to turn on the instantiated_fixtures in spec_helper thusly ... self.use_instantiated_fixtures = true Regards, Keith

Hi, While investigating the situation of visibility annotations and linkage in libc++ with the goal of removing uses of `__always_inline__`, Eric Fiselier and I stumbled upon the attached test case, which I don't think Clang compiles properly. Here's the gist of the test case, reduced to the important parts (see the attachment if you want to repro): // RUN: %cxx -shared -o

I''m working on a website which interacts with Amazon web services. I have an Item class which is a cache for amazon items. I''d like to have the class instances to refresh data every day (Time.now - item.last_updated > 1.day) but not sure how. I''ve tried with class Item < ActiveRecord::Base # ... private def instantiate(record) super

Is there any way to get AR to instantiate a different class when using STI? Where it would normally instantiate Digit, I would like it to instantiate SkelDigit. Here''s why... My rails app has the following STI hierarchy: Digit < Glyph < ActiveRecord::Base My migrate script can''t use those classes directly however (backward compatibility issues), so I created some

Hey everyone, I''m trying to find a work around for a performance problem I''ve been having. I have a class that builds paths (among other things) dynamically to many files and folders depending on what sets of information the user accesses. Once built, this class instantiation contains all the information necessary for several pages (controllers/views) to operate. However at

Hi I am the maintainer of pygccxml, which uses clang/llvm and CastXML to parse c++ code. A user reported a problem with the current llvm 3.9 trunk version (I tested with r261262). Our problem is that the AST contains some declarations which were not there before. Using "clang -Xclang -ast-dump” on a c++ file, I get the following result: TranslationUnitDecl 0x8e41ab0 <<invalid

Hello, I am working on a tool which takes c++ header files and based on interfaces defined in them generates csharp classes and glue layer for interop. For analyzing the c++ code I am currently using clang, which parses the headers and writes output into xml via -ast-print-xml (yes, this unfortunately means that it is a very old version of clang). I then use these xml files to generate the csharp

Is the original definition of the template available in the XML file, not just the reference to the specific instantiations (i.e. IMyEnumerator<int>).

OK, we all know that Rails turned off instantiated fixtures by default in 1.0. That''s not a problem. However, what I''m now wondering is how to access the raw fixture data out of the YML file (as opposed to the database.) Mainly, for comparing my database results with my expected results in a DRY way. The book says if you have the command "fixtures :foo", that

My gut tells me that if it isn't already available, then it will be difficult as the instantiation has to occur for the final compilation, but that must be occurring in a later phase of compilation than the one where the XML file is generated. Their is also a good chance that the instantiation depends on information that isn't available until after the XML file is generated (things like

I''m modifying a shopping cart plugin, MinimalCart, and for some reason I can add one item to the cart multiple times, but as soon as I add a second item, all kinds of strange things start happening. An actionview::template error is thrown because a method defined in application_helper is "undefined" What could cause a defined application helper method to all the sudden not be

I just moved my app from development to test, and now getting the following error on my form: undefined method ''find'' for Status:Class The only difference between the two environments is that test is using Mongrel and we were running WEBrick in dev. We are on Rails 1.2.5 . Any suggestions? Thanks, Brian -- Posted via http://www.ruby-forum.com/.
