Hello everyone, I''m having trouble figuring out which approach is better. I have the following tables: products, orders and line_items. Every time an Order is placed, the quantity field in the products table has to be updated for each LineItem in the Order. One option is to use DB triggers which is not as portable as using before_create in the Order model. But with before_create I cannot

Hi I''d like to know how to have ActiveResource generate a URL for the /teams/1/edit type of resource. I''ve got custom_methods.rb and have used Team.find(1).get(:edit) This generates http://localhost:xxxx/teams/1/edit.xml But all I get returned is a hash of the attributes (in this case of team 1), rather than an object of team 1. In other words the

Hi, I have a very sime app. I need to create as many records in the db as the selected checkboxes (named :isselected) in the view. Here is the code snippet from the controller: isselectedhash = params[:isselected] for mod in isselectedhash.keys @issue = Issue.new(params[:issue]) @issue.state = ''NEW'' @issue.mod_id = isselectedhash[mod] # this gets

I have a problem displaying images when using attachment_fu. When I try to display the image, only about 40k appears in the browser, and with some images even that much is not visible (just garbage when I view source). I can display images smaller than 40k correctly. I''m storing the images in the database (mysql) and haven''t tried storing in the file system to see if that works

Hi all, please help me: First time I totally had to delete all ruby and Rails because of this problem. How to solve it well?

Has anyone hacked Builder::XmlMarkup to dasherize underscore tags by default? I know I can use tag!, but I''d like to find a way for it to translate underscores to dashes automatically. In other words: xml.department_manager do "fred end #=> <department-manager>fred</department-manager> I tried hacking Builder::XmlBase.method_missing but got myself all twisted up!

We have a product where our customer is "allowed" to make minor changes to the .rhtml views. Obviously, this can be an issue when updating the software, as changes need to be merged in. Also, sometimes the customer wants to back out there change but no longer has the original file. SOOO.... I''d like to tell them - if you want to change a .rhtml file - just copy it to

Hi All! This is not a problem in general but i''ve just missed the point. If my application has a global state, which i have to use both throughout ActionController and ActiveView, then, where to place that state? E.g. if I do this: class ApplicationController < ActionController::Base protected def authenticated? !user.nil? end end then I can''t use that from any

See the blog post at http://blog.lonestarsoftware.net/2007/03/09/active_resources-010-released/ Reading through the rails blogosphere last week, I read a post (which I can not find again) that suggested a completely different approach to AJAX use in rails apps. The idea was to create a Javascript proxy to the ActiveRecord models and allow AR operations to be called from the client. I see this

Hi all, I would first like to introduce myself to the Ruby on Rails (RoR) community and to say that I hope to begin to build some relationships with other RoR developers. I''m a long time Java programmer (5+ years). Java was my first experience with Object Oriented Programming (OOP). Before Java I developed using many other languages including C, Pascal, Fortran, BASIC, Visual Basic,

Hello, (shamelessly adapted to my needs from a old message from this list) I want to integrate status messages over xmpp in my Rails application. My problem is that I do not want to establish a connection to the jabber server each time a message is sent and disconnect the connection afterwards. So I am looking for a solution to establish the connection and use this connection in my controllers

Hi, I''m trying to serve the iPhone a video file from my controller using send_file. However, it appears as thought the iPhone requires byte- range request support and rails doesn''t seem to support this. If I give the iPhone a url that points to an actual file (i.e. it''s served by my webserver nginx, instead of rails) it downloads and plays it fine. Here is the proof
