Hi all, Slightly OT, but is there any way to run command-line programs through Ruby? I have a rails web application that performs some database work. After a certain action is performed, the rails app should then call a java program that performs additional work to our mainframe. This is under Win 2003 Server. Any ideas?

I know this shouldn''t be in the view but to test the code it is. Anyway if I do just session[user] I get back the user id (the id from the user table) which is good. However this code does not work. <% a = session[:user] %> <% uname = User.find(:first, :conditions => id = a) %> <%= @uname %> TIA Stuart

Hey guys, This is the final list of the new maintainers of each plugin. We need two more things to do: First please the owners of the repos add the rest of the maintainers. Second I will add a note on each rails/plugin mentioning this repos updates. So from now on, if someone else is interested in helping/contributing please send a message to the appropriate repo owner. verification

I was wondering if rails had any means of restricting access to an action in a controller (like they can''t type in url.com/cont/action, that would throw an error). The thing is I would like to be able to access this method/action through a call to render_component, so therefore, I don''t think private methods will work. So basically I am looking for something that cannot be

I have an application that worked fine, but after the recent updates has broken in some calls to render_component from views. I might be missing something but as far as I remember Rails updates is the only thing I''ve done in between. See the log: *** START LOG SNIPPET Start rendering component ({:params=> {:center_id=>10, :id=>25},

I''m calling render_component in a helper. render_component :controller => target_controller, :action => "show", :id => target_id This works fine, except that passing the id in :params didn''t work and I had to pass in an explicit :id parameter to get the target controller to override the id - is that documented anywhere? That''s not my question. My

Hi All, Silly newb question. Is there a reason why :layout is unimplemented in render_component() ? I''m looking at a situation where that would *seem* to be the right answer. Are there any patches available to add this? JK

Hi All, Anyone know if there is a way to detect whether a request came from a render_component call? There isn''t anything obvious from looking at the source, but it would be useful as I have set up a logging filter in my application.rb, and I''d prefer to exclude all component renders, since they just add extra lines to my log (I guess I could exclude identical rows at the db

Using Rails 1.1.2 and ruby 1.8.4 I''m having a weird issue with the flash when using render_component for an action inside different controller than the one from which you render. I''m passing an object via flash across a couple of actions (new and create) behind the scenes using flash.keep(:object). It works fine if the component I''m rendering is in the same

Hi I''m working on a program which relies on heavy cache sweeper usage. I''ve just bumped onto an odd problem. When using render_component method in layouts or templates with cache sweeping turned on, Rails throws an exception with the following message: NoMethodError in TestController#index You have a nil object when you didn''t expect it! The error occured while

Hello all. Am relatively new to RoR and I am pondering how to do something without using components since they appear to be "coda non grata". I have a standard layout that is used by all controllers. In this layout I want to list the next 5 events that are upcoming based on todays date. These events are currently stored in the Event model (created using scaffolding). Currently only

I need to save the output of my rails app to a file. i.e. instead of rendering a page when using "render :action=>:any_action" i want the output to be saved to a file. Anyone got any ideas? Thanks Chris -- Posted via http://www.ruby-forum.com/.

Hello folks, I use to think that a relational databases without foreign keys constraints enforced strictly by the RDBMS were no good, piece of crap, data junk. However, I''ve also learned the hard way that FKs constraints imposes serious difficulties when moving data around, specially between different DBs, or for loading test data or for upgrading DBs schemas, or for porting DBs
