• updating rails to 2.3.6

  - by Nik

  can you update your 2.3.5 app with just "gem update rails" and change the version # in environment.rb? I did that and lots of errors came out like in console just typing Post.all would show "undefined method `retrieve_connection' for nil:NilClass". Any ideas? By the way, I have these gems in my environment.rb config.gem "aws-s3", :version = "= 0.6.2", :lib = "aws/s3" config.gem "less" config.gem "authlogic" config.gem "be9-acl9", :source = "http://gems.github.com", :lib = "acl9" config.gem "hash_extension" config.gem "prawn"

• XML Schema (XSD) to Rails ActiveRecord Mapping?

  - by Incomethax

  I'm looking for a way to convert an XML Schema definition file into an ActiveRecord modeled database. Does anyone know of a tool that happens to do this? So far the best way I've found is to first load the XSD into an RDBMS like postgres or mysql and then have rails connect to do a rake db:schema:dump. This however, only leaves me with a database without rails Models. What would be the best way to import/load this xsd based database into rails?

• will_paginate with named_scopes

  - by Lowgain

  I'm using will_paginate for pagination, which has been working well so far, except for this one thing. If I try to paginate a scope, for instance class User < ActiveRecord::Base named_scope :scope, lambda { etc } end User.scope.paginate({:page => params[:page], :per_page => 10}) That will tell me paginate is an undefined method. I'd rather not have to use a second solution for only this scope, is there something I can do here?

• Rails: find by day of week with timestamp

  - by Sleepycat

  I need to grab the records for same day of the week for the preceeding X days of the week. There must be a better way to do it than this: Transaction.find_by_sql "select * from transactions where EXTRACT(DOW from date) = 1 and organisation_id = 4 order by date desc limit 7" It gets me what I need but is Postgres specific and not very "Rails-y". Date is a timestamp. Anyone got suggestions?

• Webrick transparent proxy

  - by zzeroo

  Hi there, I've a absolute simple proxy running. require 'webrick' require 'webrick/httpproxy' s = WEBrick::HTTPProxyServer.new(:Port => 8080, :RequestCallback => Proc.new{|req,res| puts req.request_line, req.raw_header}) # Shutdown functionality trap("INT"){s.shutdown} # run the beast s.start This should in my mind not influence the communication in any way.

• ActionMailer: Default From: address?

  - by Alexandre

  Googled for this to no avail. Didn't find anything in the API either. I was expecting some kind of class method or configuration option to set it... So, rather than calling from "[email protected]" for every method, it could be called automatically.

• Nasty deep nested loop in Rails

  - by CalebHC

  I have this nested loop that goes 4 levels deep to find all the image widgets and calculate their sizes. This seems really inefficient and nasty! I have thought of putting the organization_id in the widget model so I could just call something like organization.widgets.(named_scope), but I feel like that's a bad short cut. Is there a better way? Thanks class Organization < ActiveRecord::Base ... def get_image_widget_total total_size = 0 self.trips.each do |t| t.phases.each do |phase| phase.pages.each do |page| page.widgets.each do |widget| if widget.widget_type == Widget::IMAGE total_size += widget.image_file_size end end end end end return total_size end ... end

• wxruby - Set max length of ComboBox

  - by Jonas Söderström

  Is is possible to set the Max length of a ComboBox in wxruby? I have looked in the documentation but find nothing http://wxruby.rubyforge.org/doc/combobox.html But if i do my_combobox.methods.sort I get set_max_size and set_min_size in the list. But When I call it my_combobox.set_max_length(100) I only get undefined method 'set_max_length' for #<Wx::ComboBox:0x4d4a914> I've also tried to call it as a private method def my_combobox.max(i) set_max_length(i) end my_combobox.max(100) But with the same result. The issue I want to avoid is that if somebody pastes 6000+ characters in my Combobox the text becomes white.

• Rails: Cannot add :precision or :scale options with change_column in a migration?

  - by Josh Pinter

  This seems to have been asked before: http://stackoverflow.com/questions/1402547/rails-decimal-precision-and-scale But when running a change_column migration for :precision or :scale they don't actually affect the schema or database, but db:migrate runs without errors. My migration file looks like this: class ChangePrecisionAndScaleOfPaybackPeriodInTags < ActiveRecord::Migration def self.up change_column :tags, :payback_period, :decimal, { :scale => 3, :precision => 10 } end def self.down change_column :tags, :payback_period, :decimal end end But my schema (and the data) remains as: t.decimal "rate" # previous column t.decimal "payback_period" t.string "component_type" # next column Anybody else have this issue? Thanks, Josh

• Admin interface in Rails

  - by yuval

  I have an admin controller located in controllers/admin/admin_controller.rb I also have a pages controller located in controllers/admin/pages_controller.rb pages_controller.rb inherits from admin_controller.rb in routes.rb, I have an admin namespace as such: map.namespace :admin do |admin| admin.resources :pages end I want the admin have basic CRUD functionality in pages_controller.rb (I know how to do that) I want the index and show methods to be available to front-end users I would like the show and index actions to use separate views, but the same code. Questions: Should I create a new pages_controller for the front-end, or share the methods index and show? If share, how would I display separate views depending on whether the url is /admin/pages or /pages If share, should I place pages_controller in /controllers/admin (where it is now) or just in /controllers? Thank you very much.

• Cucumber Error: Socket Error for Test Environment Host in REST API

  - by tmo256

  I posted this to the Cucumber group with no replies, which makes me wonder if this is actually a cucumber issue or not. I'm pretty new to cucumber, and there are a number of things I really don't quite understand about how the cucumber environment is set up and executed within the test environment. I have a REST API rails app I'm testing with cucumber, using the RestClient gem to generate a post to controller create action. When I run the feature with a hard-coded URL pointing to a running localhost server (my local dev server environment; replacing tickets_url with "http:// localhost/tickets" in the snippet below), my cucumber steps execute as expected. However, when the resource URL resolves to the cucumber host I'm declaring, I get a socket error exception. getaddrinfo: nodename nor servname provided, or not known (SocketError) From the steps file: When /^POS Adapter sends JSON data to the Tickets resource$/ do ticket = { :ticket = { ... } } host! "test.host" puts tickets_url RestClient.post tickets_url, ticket.to_json, :content_type = :json, :accepts = :json end (the "puts" statement prints "http://test.host/tickets") Using the following gems: cucumber-0.6.1 webrat-0.6.0 rest-client-1.2.0 I should also say I have a similar set up in another rails app, using test.host as my host, and it seems to work fine. I'd appreciate any insight on what I might be missing in my configuration or what this could be related to.

• Pasting images in TinyMCE on rails app

  - by Sam Kong

  Hi, I found a weird problem with TinyMCE editor. Copying & pasting images from another domain works fine but if the images are on the same domain the path are relative but not correct sometimes. I figured out that the problem is related to the rails URL scheme. Example) Images are copied from http://mydomain.com/index.html page and the real images path is http://mydomain.com/photos/image.jpg. Editor page: http://mydomain.com/posts/new = image path is set as ../photos/image.jpg http://mydomain.com/posts/edit/123 = image path is set as ../../photos/image.jpg So I tried http://mydomain.com/posts/new/ and it worked. How do I solve this problem? Thanks. Sam

• Changing Render Kits in Browser

  - by John

  I'm working on a project to develop a cross-browser testing web app. Simply put, I'm tired of having to maintain multiple browsers on the same system and IE in VMware solely for the purpose of testing. Does anyone know if there is any way to change the render kit programmatically? For example, if I insert a URL, I would be able to load the URL and switch the browser render within a frame of some assortment. I am experienced with PHP, JS, and RoR if there is a solution using any of those. Thank you! John

• How to log into a salesforce.com sandbox?

  - by wesgarrison

  I took over a Rails app and am trying to get the Salesforce.com API credentials set up for my user account. I'm set as a system admin with "Developer Mode" on (though I have no clue what that does, I just saw it set on the previous account.) We have a sandbox. I click the login link on it, enter my sandbox username ([email protected]), enter my password, and get "Login attempt has failed". I know my password is okay since I've logged into the production site several times. Using different domains (test.salesforce.com, etc) doesn't help either.

• Why can't I set boolean columns with update?

  - by Benjamin Oakes

  I'm making a user administration page. For the system I'm creating, users need to be approved. Sometimes, there will be many users to approve, so I'd like to make that easy. I'm storing this as a boolean column called approved. I remembered the Edit Multiple Individually Railscast and thought it would be a great fit. However, I'm running into problems which I traced back to ActiveRecord::Base#update. update works fine in this example: >> User.all.map(&:username) => ["ben", "fred"] >> h = {"1"=>{'username'=>'benjamin'}, "2"=>{"username"=>'frederick'}} => {"1"=>{"username"=>"benjamin"}, "2"=>{"username"=>"frederick"}} >> User.update(h.keys, h.values) => ... >> User.all.map(&:username) => ["benjamin", "frederick"] But not this one: >> User.all.map(&:approved) => [true, nil] >> h = {"1"=>{'approved'=>'1'}, "2"=>{'approved'=>'1'}} >> User.update(h.keys, h.values) => ... >> User.all.map(&:approved) => [true, nil] Chaging from '1' to true didn't make a difference when I tested. What am I doing wrong?

• Which persistent & lightweight queue messaging for cross domain (> 2) data exchange with rails integ

  - by Erwan

  Hi all, I'm looking for the right messaging system for my needs. Can you help me ? For now, there won't be a huge amount of data to process, but I don't want to be limited later ... The machines are not just web servers, so the messaging tool should be lightweight, even if processing is not very speed. When some data change on a server, all servers should have the information and process it locally. (should I create one channel per server on each of them ?) The frontend is written on Rails, so it is important, in order to simplify the development, that there is a gem / plugin to manage communications and data sent. At this time : RabbitMQ + workling seems to fit my needs. Could this be a right choice ? ActiveMQ make me afraid, because of Java (I really don't know very well Java, but it seems to me to be big CPU consumer) Others don't seem to be as mature as them. There might be lot of development using this kind of technology, so I can't go to the wrong way ! Thank you for help.

• Using a dynamic number of checkboxes in a rails form

  - by TenJack

  I am trying to create a form with a dynamic number of checkboxes that each link to a string that is not a model number but is instead just a word. For examples: <% form_for(@words) do |f| %> <% ["apple","banana","orange"].each do |word| %> <%= f.check_box :word %> <%= f.submit %> <% end %> <% end %> So, if "apple" was checked, it would just send the string "apple" in the params. Anyone know how to do this?

• Regex issue with comma's telling me there are 6 args, instead of intended 4

  - by Azher

  I have a scenario outline table that looks like the following: Scenario Outline: Verify Full ad details Given I am on the xxx classified home page And I have entered <headline> in the search field & clicked on search When I click on full details Then I should see <headline> <year> <mileage> <price> displaying correctly and successfully Examples: |headline |year |mileage |price | |alfa romeo 166 |2005 |73,000 |6,990 | When I run my scenario it spits out that I have 6 args. But what I thought, I should only have 4 args: headline, year, mileage and price. I am thinking that it is taking the comma's and what is before and after it as two seperate args. Is there any way that I can make cucumber think that there are only 4 args with the example below? I have looked at messing around with regex but I dont seem to be getting anywhere. Any help would be greatly appreciated.

• Rails: Object#id will be deprecated; use Object#object_id

  - by sscirrus

  Hi everyone, Very quick question. My server is warning me that line 37 will be deprecated, specifically: #Server error: views/projects/index.html.erb:37: warning: Object#id will be deprecated; use Object#object_id #Views/projects/index.html.erb: 6: <% for project in @projects do %> 36: <%= project.id %> 37: <%= Matching.find_all_by_customer_id_and_project_id( @customer.id, project.id).id %> 38: <%= @customer.id %> Here's my confusion. Line 36 project.id isn't raising a warning, so I assume the issue is that I'm calling ID on the Matching model. Why is it the case that only Matching raising an error and not customer or project? How can I rectify this in my code? Thanks very much.

• SQLServer Binary Data with ActiveRecord and JDBC

  - by John Duff

  I'm using the activerecord-jdbc-adapter with ActiveRecord to be able to access a SQLServer database for Rails Application running under jRuby and am having trouble inserting binary data. The Exception I am getting is below. Note I just have a blurb for the binary data from the fixtures that was working fine for MySQL. ActiveRecord::StatementInvalid: ActiveRecord::ActiveRecordError: Operand type clash: nvarchar is incompatible with image: INSERT INTO blobstorage_datachunks ([id], [datafile_id], [chunk_number], [data]) VALUES (369397133, 663419003, 0, N'GIF89a@') When I created the tables the migration had binary and SQLServer used Image instead. We're using Rails 2.3.5, SQLServer Express 2008. What I'm looking for is a way to get the binary data into SQLServer with ActiveRecord. Thanks in advance for the help.
