Hi, I''ve developed a standalone Rails app - using tar2rubyscript and rubyscript2exe. The users aren''t going to understand that the''ll need to open the browser and go to 127.0.0.1:3000 to view the app, after running the exe. I am wondering whether other people have tackled this problem in the past, and how they went about solving it. One way would be to write a

Hi, I need to download an image, and I''ve mucked about with Net::HTTP resp = Net::HTTP.get_response(''www.mydomain.com'', ''/test.jpg'') f = File.new("test.jpg","w") f.write(response.body) And various other combinations using HTTP.get etc. Anyway, I get an image, but it looks very psychedelic. This is obviously not the correct way.

Is there a way for me to do: OrderItem.find(:all, :include => [:user, :product => [:supplier]] So I don''t have a supplier_id on my order_item, but have it on my product, which is part of order_item. Joerg -- Posted via http://www.ruby-forum.com/.

Hi, I have method I want to call ... it can receive * number of parameters. I also have 3 parms that I want to pass often, so I have defined them in a separate function: def my_params { :parm1 => 1, :parm2 => 2, :parm3 => 3 } end And I want to call my method like this: mymethod :parm4 => 4, my_params Now - this doesn''t work - as my_params is a hash of params, which

Hi I have my routes set up like this: map.resource :contact, :path_prefix => "/employers/:employer_id" so now when I view all contacts for an employer I go to: /employers/1/contacts That works. On that page, there''s a problem with the routes: new_contact_url translates to: /employers/1/contacts/new ... so that works. But, contact_url(@contact) gives me

Hi, When calling remote functions (AJAX), I can test for :success and :failure. But how do I return a :success or :failure to my AJAX function call from my action? Thanks Joerg -- Posted via http://www.ruby-forum.com/.

Hi, I have a webservice. And I want to pass in, a model. So, for example: api_method :save_person, :expects => [Person] When I do this I get an error saying that I cannot have ActiveRecord objects as parameters. Fine. I can have AWS Structs as parameters.

Hi folks, I am running an offline Rails app that periodically connects to the Internet to download the latest catalogue, and upload any new orders. I am about to implement the synching bit - and was thinking whether there is any other solution other than writing webservices and code to do a manual sync of the data, or whether there is a more nifty and robust way using say replication?

I have a loop that I iterate through in my view. <% coll.each do |itm| puts(itm.value) end %> How do I render the itm.value without using a <%= %> tag? Should puts not work? Joerg P.S. There is a good enough reason for me wanting to do this :-) -- Posted via http://www.ruby-forum.com/.

Hi, Not sure where to address this question ... but I guess this is a good start. I am a freelance Rails developer - and have been developing Rails apps professionally for about a year now. I just want to get an idea of what you other freelancers charge yourselves out at. I have been charging the equivalent of about $28/hour, but get a sense that I could/should charge a whole lot more. I am

Is there a way to add a mime type of my own to respond_to ? There''s html, xml, js, ical etc ... But I want to be able to respond_to Excel. Excel has the following content-type header: application/vnd.ms-excel I want to use the new ?format=xml querystring parameters that respond_to can respond to. So I want to pass in ?format=xsl or ?format=ms-excel so that I can return my results

Hi - I have a fresh install of OSX, Rails, Ruby, Ferret, AAF etc ... Everything is working fine, I can start mongrel, I can start backgroundrb, but Ferret Drb ... doesn''t want to work. RAILS_ENV=development script/ferret_start Gives me: env: script/runner: Permission denied Is there a way I can debug this to figure out what is going on - or is there another way to start Ferret Drb?

Hi, I have been running ferret for several months now, but want to make use of the new Drb functionality. So I am running Rails Stable (off the branch), Ferret 0.11.4, and the latest AAF. I have a ferret_server_yml file in my RAILS_ROOT/config folder: production: host: localhost port: 9009 pid_file: log/ferret.pid And I took the three scripts from the AAF plugin and put them into my

I''m using Edge Rails: Has anybody used :group (and say :sum) in a find method? It seems to ignore it, and my generated sql contains no mention of GROUP BY. Or am I not getting it? -- Posted via http://www.ruby-forum.com/.

Hi, I have the following: order = YAML::load(order_yaml) The YAML contains order_items too, and my order model has a has_many to order_items. When I do order.order_items, I don''t want Rails to go the db to get the order_items, but use the order_items already contained in the object created from the YAML. How would I do this? Thanks Joerg -- Posted via

Some long-running AJAX calls are returning Execution Timeout errors - though after a few seconds already which I find very strange, as on other computers I can run these AJAX scripts for 10 minutes without timeouts. Is there a setting somewhere, that I can set to adjust my timeout value? Or am I barking up the wrong tree? Thanks Joerg -- Posted via http://www.ruby-forum.com/.

In my tests, I want to invoke my webservice not using the default SOAP protocol, but using XmlRpc ... how do I do that? -- Posted via http://www.ruby-forum.com/.

Hi, I want to make a copy of an object with its associations, and I am looking for an elegant solution. This is what I intuitively think should work, but it doesn''t: order2 = order1.clone order1.line_items.each do |o| order2.line_items.build(o) end This doesn''t work because a model class does not stringify its keys ... so I can''t pass an object into a method that
