• Rails logger messages test.log?

  - by Dave Paroulek

  Is it possible to configure rails to show logger.debug messages (from logger.debug statements inside controllers) to display inside test.log (or to the console) when running unit and functional tests? I added the following to test_helper.rb. I see messages from logger.debug statements directly inside tests but no messages from logger statements inside controller methods? def logger RAILS_DEFAULT_LOGGER end

• Rails rspec expects Admin::PostsController, which is there.

  - by berkes

  I have a file app/controllers/admin/posts_controller.rb class Admin::PostsController < ApplicationController layout 'admin' # GET /admin/posts def index @pposts = Post.paginate :page => params[:page], :order => 'created_at DESC' end # ...Many more standard CRUD/REST methods... end And an rspec test spec/controllers/admin/posts_controller_spec.rb require 'spec_helper' describe Admin::PostsController do describe "GET 'index'" do it "should be successful" do get 'index' response.should be_success end end #...many more test for all CRUD/REST methods end However, running that spec throws an error. I have no idea what that error means, nor how to start solving it. /home/...../active_support/dependencies.rb:492:in `load_missing_constant': Expected /home/...../app/controllers/admin/posts_controller.rb to define Admin::PostsController (LoadError) I may have it all set up wrong, or may be doing something really silly, but all I want is my CRUD actions on /admin, with separate before filters and a separate layout. And to test these controllers. EDIT ZOMG, made a terrible copy-paste error into this SO posting. The controller was PostsController, not the PagesController that I pasted into there. Problem still stands, as my code is correct, just the SO post, here was wrong.

• Rails override validator message

  - by Anand

  Hi, I have a site thats served in 2 flavours, English and French. Here's some code app/views/user/register.html.erb ----------------- <% form_for .....> <%= f.text_field :first_name %> <% end %> app/models/user.rb ------------------ class User < ActiveRecord::Base validates_presence_of :first_name end Now to display the error message in case if the site is being served in the French version, I have app/config/locales/fr.yml ------------------------- activerecord: errors: messages: empty: "ne peut pas être vide" So if someone does not fill in a first name, the validator takes the name of the field and appends the custom message for empty clause giving "First name ne peut pas être vide" which is incorrect, coz 'First name' in French is 'Prénom', hence it should be "Prénom ne peut pas être vide" Please can someone suggest a way of achieving the desired result.

• Is it Me or Are Rails and Django Difficult to Install on Windows?

  - by Mackristo

  I tried getting these frameworks working on Windows Vista for a couple of days but to no avail. Every single time I thought I had them working I would get some random error involving the PostgreSQL or MySQL setup, or the paths were screwed up or some other command line error "not recognized as an internal or external command" (or something). Someone told me that these frameworks are a lot easier to get running on Ubuntu but I really don't want to make that switch as everything I have is on Windows. Are these common problems when trying to get running on Windows? I think I'll just stick with C# and .NET as everything seems to work pretty nicely together with none of this "install-twenty-different-components" stuff and see if they work together. Is Instant Django advisable to use?

• Iterating Over Params Hash

  - by Joe Clark

  I'm having an extremely frustrating time getting some images to upload. They are obviously being uploaded as rack/multipart but the way that I'm iterating over my params hash must be causing the problem. I could REALLY use some help, so I can stop pulling out my hair. So I've got a params hash that looks like this: Parameters: {"commit"=>"Submit", "sighting_report"=>[{"number_seen"=>"1", "picture"=>#<File:/var/folders/IX/IXXrbzpCHkq68OuyY-yoI++++TI/-Tmp-/RackMultipart.85991.5>, "species_id"=>"2"}], "authenticity_token"=>"u0eN5MAfvGWtfEzrqBt4qfrL54VJ9SGX0jFLZCJ8iRM=", "sighting"=>{"sighting_date(2i)"=>"6", "name"=>"", "sighting_date(3i)"=>"5", "county"=>"0", "notes"=>"", "location"=>"", "sighting_date(1i)"=>"2010", "email"=>""}} My form can have multiple sighting reports with multiple pictures in each sighting report. Here's my controller code: def create_multiple @report = Report.new @report.name = params[:sighting]["name"] @report.sighting_date = Date.civil(params[:sighting][:"sighting_date(1i)"].to_i, params[:sighting][:"sighting_date(2i)"].to_i, params[:sighting][:"sighting_date(3i)"].to_i) @report.county_id = params[:sighting][:county] @report.location = params[:sighting][:location] @report.notes = params[:sighting][:notes] @report.email = params[:sighting][:email] @report.save! @report.reload for sr in params[:sighting_report] do sighting = SightingReport.new sighting.report_id = @report.id sighting.species_id = sr[:species_id] sighting.number_seen = sr[:number_seen] sighting.save if sr[:picture] sighting.reload for pic in sr[:picture] do p = SpeciesPic.new p.uploaded_picture = pic p.species_id = sighting.species_id p.report_id = @report.id p.save! end end end redirect_to :action => 'new_multiple' end

• Fill a rails form with a hashmap

  - by Ignace

  Hey, I have a difficult situation. I let the the user create a form through a Rich Text Editor and then I save this. So for example, I save this literally into my DB: http://pastebin.com/DNdeetJp (how can you post HTML here? It gets interpreted, so now I use pastebin...) On another page I wrap this in a form_tag and it gets presented as it should be. What I want to do is save this as a template and save the answers as a hashmap to my DB. This works well, but the problem is I want to recreate what checkbox/radiobutton/... is selected when the user goes back to the page. So I want to fill the form with the answers from the hashmap. Is there a way to use a 'dummy' model or something else to accomplish this? Thanks!

• Flash/Flex sending XML to Rails App

  - by bdicasa

  I'm trying to send some XML to a rails app in Flex. I'm using the URLRequest and URLLoader objects. However, I'm having trouble determining how to send the XML and _method parameter to the rails app using these flash objects. Below is how I'm currently trying to achieve this. var request:URLRequest = new URLRequest(); request.method = URLRequestMethod.POST; request.data = new Object(); request.data.xml = Blog.xml.toXMLString(); request.contentType = "text/xml"; var loader:URLLoader = new URLLoader(); loader.addEventListener(Event.COMPLETE, saveCompleteHandler); var saveUrl:String = ""; saveUrl = BASE_URL; if (Blog.isNewBlog) { // Set the rails REST method. request.data._method = "POST"; saveUrl += "blogs.xml"; } else { // Set the rails REST method. request.data._method = "PUT"; saveUrl += "blogs/" + Blog.id.toString() + ".xml"; } request.url = saveUrl; //trace(request.data.toString()); loader.load(request); However the only data that is getting sent to the server is [Object object]. If some one could let me know where I'm going wrong I'd greatly appreciate it. Thanks.

• Using Bundler along with preinstalled gems

  - by Rob Cameron

  So I've got thin installed the old fashioned way: gem install thin I put an app on the server and installed all of its required gems via bundler: bundle install But, when I tried to start the app with thin start, it can't find any of the bundler-installed gems since they're not installed in the default gems directory. My question is: how do I make this work? Do I need to install thin via bundler as well? Will that still set up the thin executable in /usr/bin so I can start it from the command line like normal? Thanks!

  Hi I have a controller named "places" with some actions like "view", "new", "create" When a user goes to mysite.com/places I want to execute the action "show" of another controller called "cores" So I've put this in the routes.rb file: map.connect '/:id/show', :controller => "cores", :action => "show" But it doesn't work.

• Synchronize locale yml files tool in Rails

  - by Konstantinos

  I was wondering, is it possible to synchronize with any tool or gem or w/e 2 or more yml files? eg. i have the Greek yml file called el.yml el: layout: home: "??????" and the english one called en.yml en: layout: home: "Home" category: "Category" Is there any tool that based on a single yml file ie en.yml ( root ) that goes to the rest of the ymls and creates the missing translations with the default (en.yml) values? After running such a tool i would expect to have the el.yml become likes this: el: layout: home: "??????" category: "Category" I am using a similar tool in .NET RESX Synchronizer and it does exactly that, but for resx files.

• Google Maps integration with JSON - CircularReferenceError

  - by JZ

  I'm working on Rails 3.0.0.beta2, following Advanced Rails Recipes "Recipe #32, Mark locations on a Google Map" and I hit a road block. The following code is returning a "ActiveSupport::JSON::Encoding::CircularReferenceError" "object references itself" at line 3. This code represents the /layouts/maps.html.erb file <% if @maps -%> <script type="text/javascript"> var maps = <%= @maps.to_json %>; </script> <% end -%> This is my first attempt at rendering JSON, and I don't know how to debug this problem. Do you have experience with this? What could cause this problem? Thank you in advance!

• Rspec Selenium. Test to check certain Ajax functions passes when i expect it to fail.

  - by alokswain

  I am testing a Ajax action using Rspec and Selenium. My story is as follows: it "should create a new User with any input" do @browser.open "/people" @browser.wait_for_page_to_load "2000" @browser.type "user_name", "Alok Swain" @browser.click "user_submit" @browser.text?("Alok Swain").should be_true end The action i am testing is: def add_user @users = User.all User.create(params[:user]) render :update do |page| page.alert "Created User" page.replace_html "users", :partial => '/people/users_list', :locals => {:users => @users} end end The test fails and the error I get is: 'User should create a new User with any input' FAILED expected false to be true. This test should pass right ? I also kept an alert and tried @browser.is_alert_present.should be_true but i got the same error. I tried @browser.is_text_present("test") and this test succeeded. In the test database a record was created for Alok Swain but when I tried the above assertion it passed when i expected it to fail. Is there any thing else to be done here. What am I missing ?

• Can I ensure all tests contain an assertion in test/unit?

  - by Andrew Grimm

  With test/unit, and minitest, is it possible to fail any test that doesn't contain an assertion, or would monkey-patching be required (for example, checking if the assertion count increased after each test was executed)? Background: I shouldn't write unit tests without assertions - at a minimum, I should use assert_nothing_raised if I'm smoke testing to indicate that I'm smoke testing. Usually I write tests that fail first, but I'm writing some regression tests. Alternatively, I could supply an incorrect expected value to see if the test is comparing the expected and actual value.

• Naming selenium grid nodes. Spawning a specific node

  - by ???? ????

  I'm trying to implement a kind of default queues in selenium hub. There is a possibility to specify node's name (actually its environment, smth like "firefox on ubuntu" or "chrome on windows"). Selenium grid itself has a default queue, it works according to 'First In, First Out' principle. But I want to prioritize some of my tasks given to selenium server. I have no possibility to introduce custom queue (seems like there is no API for that), that's why I decided to separate queue's logic from selenium server. I'll only call a specific node with specific name (environment) for example "firefox important node" or smth like that. So, I want to know how to directly tell selenium which node to use for my task? And generally, am I thinking in a right way? Here are my configs: hubConfig.json.erb { "host": null, "port": <%= node[:selenium][:server][:port] %>, "newSessionWaitTimeout": -1, "servlets" : [], "prioritizer": null, "capabilityMatcher": "org.openqa.grid.internal.utils.DefaultCapabilityMatcher", "throwOnCapabilityNotPresent": true, "nodePolling": <%= node[:selenium][:server][:node_polling] %>, "cleanUpCycle": <%= node[:selenium][:server][:cleanup_cycle] %>, "timeout": <%= node[:selenium][:server][:timeout] %>, "browserTimeout": 0, "maxSession": <%= node[:selenium][:server][:max_session] %> } nodeConfig.json.erb { "capabilities": [ { "browserName": "firefox", "maxInstances": 5, "seleniumProtocol": "WebDriver" }, { "browserName": "chrome", "maxInstances": 5, "seleniumProtocol": "WebDriver" }, { "browserName": "phantomjs", "maxInstances": 5, "seleniumProtocol": "WebDriver" } ], "configuration": { "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy", "maxSession": <%= node[:selenium][:node][:max_session] %>, "port": <%= node[:selenium][:node][:port] %>, "host": "<%= node[:fqdn] %>", "register": true, "registerCycle": <%= node[:selenium][:node][:register_cycle] %>, "hubPort": <%= node[:selenium][:server][:port] %> } } And my Driver class: ... def remote_driver @browser = Watir::Browser.new(:remote, :url => "http://myhub.com:4444/wd/hub", :http_client => client, :desired_capabilities => capabilities ) end def capabilities Selenium::WebDriver::Remote::Capabilities.send( "firefox", :javascript_enabled => true, :css_selectors_enabled => true, :takes_screenshot => true ) end def client client = Selenium::WebDriver::Remote::Http::Default.new client.timeout = 360 client end ... I still don't know how to use specified node for my task. If I try to start a driver adding :name => "firefox important node" and extend nodeConfig.json.erb's configuration with environments: - name: "firefox important node" browser: "*firefox" - name: "Firefox36 on Linux" browser: "*firefox" selenium just starts random firefox browser on a random node. How can I control it?

• Handling dynamic data from javascript or rails

  - by 99miles

  I have page consisting of a calendar view ( http://code.google.com/p/calendardateselect/ ) as well as divs, each of which contain information about a person. In each div I want to have a link to a new controller and action, and pass the id for the person and the date selected in the calendar. I can think of a one way, but I'm thinking there's likely a better solution: 1) Do something like: =link_to_function "Week", "weekClicked(#{person.id})" Then in the weekClicked() javascript method I get the selected date from the calendar, such as: $('e_date').selected_date; then with javascript I could make a post request as mentioned here: http://stackoverflow.com/questions/133925/javascript-post-request-like-a-form-submit 2) Or, is there a way that I could make each link a button in it's own form and maybe have a hidden field that gets the selected date from the calendar as or before the form is submitted? I tried this too, but couldn't figure it out. This definitely seems like it's more on the right track than #1. Thanks.

• How to get strptime to raise ArgumentError with garbage trailing characters

  - by Matt Briggs

  We have to handle user specified date formats in our application. We decided to go with Date.strptime for parsing and validation, which works great, except for how it just ignores any garbage data entered. Here is an irb session demonstrating the issue ree-1.8.7-2010.01 > require 'date' => true ree-1.8.7-2010.01 > d = Date.strptime '2001-01-01failfailfail', '%Y-%m-%d' => #<Date: 4903821/2,0,2299161> ree-1.8.7-2010.01 > d.to_s => "2001-01-01" what we would like, is behavior more like this ree-1.8.7-2010.01 > d = Date.strptime '2001failfailfail-01-01', '%Y-%m-%d' ArgumentError: invalid date Any suggestions would be appreciated

• rails validate_format_of non-negative integers

Instead it saves a value of 0 in the database. How do I make it write to the list of error messages. thanks

• Rails, How can I combine multiple model attributes to create a unique permalink using permalink_fu?

  - by Ranknoodle

  Can Permalink_fu combine 2 or more model attributes to create a unique permalink? Let's say I have a Business Model, this model contains :name, :address, :phone, :city, :state, :country etc. attributes. Right now I have permalink set up in this model only for :name has_permalink :name So I would get "/biz/name". However I would like to combine the Business name, city, and a incremental number if there are more than 1 location in the city for that business. For example I would like to use: "/biz/joes-coffee-shack-chicago" for the permalink or if a multple location business "/biz/starbucks-chicago-92" Is this possible with the current permalink_fu plugin or some fork of permalink_fu? Or will this require some modification to the permalink_fu plugin?

• aws-s3 can't find xml-simple, but in gem list

  - by Dan Donaldson

  I'm transitioning to heroku, and need to have AWS-s3 connections to deal with a variety of graphics. I've installed the aws-s3 gem, but one of its dependencies is not being found: xml-simple. My belief is that this is a standard part of RoR, and it is in the gem list. When I deploy to heroku, all is fine, but on my development server, it isn't being found when the code uses it to check the existence of a graphic. It works fine from the console, using s3sh. I'm not quite sure why this is -- what do I need to check? Using OS X 10.6, on a 64 bit machine -- can this be part of it?
