I have a problem, I'll simplify it down to the blog example. 1) Each 'post' is created by a different user stored in a 'User' database. 2) Several 'comments' belong to the one 'post'. 3) When a new 'comment' is made, the user who created the initial 'post' needs to be emailed. I have setup the mailer and observer. I am just not sure how...
Hi, I programmed in Ruby and Rails for quite a long time, and then I fell in love with the simplicity of the Sinatra framework which allowed me to build one page web applications. Is there a web framework like Sinatra available for Erlang? I tried Erlyweb but it seems far too heavyweight ...

I have a model that has an overriden to_param method returning the (unique) name of a record. This works quite fine, however with one caveat - the user can edit the name. If I have record #1 with name="abc" and record #2 with name="xyz", then a user editing record #2 and changing name to "abc" will get an error upon saving as the valida...

I've come across a frustrating issue with FastCGI and Rails whereby lighttpd is treating routed url's as static files (i.e. not sending them to rails since it believes they're static) If I hit the root path I get the rails application, but as soon as I hit something with a URL structure, even a path that matches the default :controller/...
Hi folks, I am stuck one more time ... and one more time I suspect it's a stupid syntax problem: I want to pass 2 vaiables in the url with my super simple search form. I was expecting a URL like this: http://mydomain/categories/search?search=pdf&os=2 But I get this: http://mydomain/categories/search?search=pdf&os[]= I though...

Hi All, I have a table with a column called lifecycle_id, and another called lifecycle_change_reason. lifeycle_id is normally changed automatically by the system based on other factors, but certain users have the ability to change the lifecycle manually. if they do, I would like to require them to provide a reason for the change, but I...
I am building a REST Web Service layer on top of a Rails app that will be used by an Iphone application. The response format is XML. I would like to build some acceptance tests that should be external to the rails stack (and should test everything, including the http server). The test scenarios are quite complex, involving the process ...
We have written a Ruby on Rails application that allows a visitor to fill out a form with personal information (name, address & other confidential details), which is stored in a database until the information can be collected by a batch process running inside institution's firewall.

I am a rails rookie and fear that my question is woefully ignorant - please be gentle. I am building an app that will catalog and monitor other websites, and need to synchronize with an external data source (thus overiding primary key). I have the model below, but i cannot figure out the routing for accessing individual records (tho li...

Currently you need to do something along the lines of: def show @user = User.find( params...
I was working on my Rails project which is checked into Git. I read tutorials and they said for everytime you start to change something, check out a branch. However, accidently I made some changes but did not check out a branch. What should I do now? What commands can I run so that Git takes my new changes and push them on my reposit...
I am interested in making a 3D pie chart dynamically on my page depending on values pulled from my database. The chart would only be updated every few days, so I don't mind a process intensive task as I could cache the image. 2D charts and pie graph libraries seem to be everywhere, but are there any libraries (server side image magic, or...

One of my controllers is doing mission-critical work and I need to know of any errors ASAP. When there is an error, I would like my app to send an email to myself, ca...
