• Facebook Cucumber testing with Authlogic - how test user logged in as facebook user?

  - by rhh

  I'm having trouble implementing this step: Given "I am logged in as a Facebook user" do end The best suggestions I can find on the web (http://opensoul.org/2009/3/6/testing-facebook-with-cucumber) do not seem to be using Authlogic for authentication. Can someone with the Cucumber/Authlogic_facebook_connect/Authlogic combo post their step for testing facebook logins? Thank you very much.

  - by Kevin Sylvestre

  What the best way to store CSPC and UPC codes are in Rails? I used integers with SQLite, but had overflow issues when moving to production. I've since switch to strings, but am not sure if a better generic datatype (needs to support SQLite, MySQL and PostgreSQL). Thanks.

• How do you unpack gems using jruby on rails 2.3?

  - by James Moore

  I'm trying to unpack all the system gems to end up with a standalone Rails directory including all the rails gems and all the system gems. I'm starting with a bare rails setup; just did a jruby -S rails and a 'generate jdbc'. I then add a config.gem 'jdbc-mysql' to environment.rb and do the jruby -S rake gems:unpack:dependencies. After unpacking, if I do a rake I get: no such file to load -- jdbc-mysql Is there something else you need to do to get the jdbc gem unpacked? I'm using jruby 1.4.0 (and moving to 1.5 is on my todo list) and rails 2.3.8.

• Restart nginx without sudo?

  - by tesmar

  So I want to be able to cap:deploy without having to type any passwords. I have setup all private keys so I can get to the remote servers fine, and am now using svn over ssh, so no passwords there. I have one last problem, I need to be able to restart nginx. Right now I have sudo /etc/init.d/nginx reload. That is a problem b/c it uses the capistrano password, the one I just removed b/c I am using keys. Any ideas on how to restart nginx w\out a password?

• Rails page caching and flash messages

  - by KJF

  I'm pretty sure I can page cache the vast majority of my site but the one thing preventing me from doing so is that my flash messages will not show, or they'll show at the wrong time. One thing I'm considering is writing the flash message to a cookie, reading it and displaying it via javascript and clearing the cookie once the message has been displayed. Has anyone had any success doing this or are there better methods? Thanks.

• gem install cannot find a header file

  - by Milktrader

  Following along the github README for talib_ruby: sudo port install ta-lib Complete. Next is where the trouble begins. sudo env ARCHFLAGS="-arch PLATFORM" gem install talib_ruby -- --with-talib-include=ABSOLUTE_PATH_TO_TALIB_HEADERS --with-talib-lib=ABSOLUTE_PATH_TO_TALIB_LIBS This install fails I believe because apparently it cannot find the ta_abstract.h file talib.c:2:25: error: ta_abstract.h: No such file or directory . . . many more errors I have included in my .bash_profile file the following: export ABSOLUTE_PATH_TO_TALIB_HEADERS=/opt/local/var/macports/software/ta-lib/0.4.0_0/opt/local/include/ta-lib export ABSOLUTE_PATH_TO_TALIB_LIBS=/opt/local/var/macports/software/ta-lib/0.4.0_0/opt/local/lib And indeed the ta_abstract.h file is located where I'm saying in the ABSOLUTE_PATH variable assignment. What gives?

• How do you prevent Git from printing 'remote:' on each line of the output of a post-recieve hook?

  I recently configured an EC2 instance with a Git deployment workflow that resembles Heroku, but I can't seem to figure out how Heroku prevents the Git post-receive hook from outputting 'remote:' on each line.

• How to always return a set number of records when using find_related_tags with acts-as-taggable-on

  - by hadees

  I'm using the acts-as-taggable-on gem and I need to use find_related_tags on my survey model to get back 3 surveys every time. In the event there aren't always 3 related I need to pick how ever many are related plus some random ones to get to 3. Additionally I have a method I wrote called completed_survey_ids which return an array of survey_ids that shouldn't be used because the user has already completed them. Also there is a rare case that there won't be enough surveys because the user has completed them all so in that event it is okay to return less surveys then requested. I did write a named_scope to handle getting rid of the completed_survey_ids that I think works named_scope :not, lambda { |survey_ids| {:conditions => "id NOT IN (#{survey_ids.join(',')})" } }

• active record relations – who needs it?

  - by M2_

  Well, I`m confused about rails queries. For example: Affiche belongs_to :place Place has_many :affiches We can do this now: @affiches = Affiche.all( :joins => :place ) or @affiches = Affiche.all( :include => :place ) and we will get a lot of extra SELECTs, if there are many affiches: Place Load (0.2ms) SELECT "places".* FROM "places" WHERE "places"."id" = 3 LIMIT 1 Place Load (0.3ms) SELECT "places".* FROM "places" WHERE "places"."id" = 3 LIMIT 1 Place Load (0.8ms) SELECT "places".* FROM "places" WHERE "places"."id" = 444 LIMIT 1 Place Load (1.0ms) SELECT "places".* FROM "places" WHERE "places"."id" = 222 LIMIT 1 ...and so on... And (sic!) with :joins used every SELECT is doubled! Technically we cloud just write like this: @affiches = Affiche.all( ) and the result is totally the same! (Because we have relations declared). The wayout of keeping all data in one query is removing the relations and writing a big string with "LEFT OUTER JOIN", but still there is a problem of grouping data in multy-dimentional array and a problem of similar column names, such as id. What is done wrong? Or what am I doing wrong? UPDATE: Well, i have that string Place Load (2.5ms) SELECT "places".* FROM "places" WHERE ("places"."id" IN (3,444,222,57,663,32,154,20)) and a list of selects one by one id. Strange, but I get these separate selects when I`m doing this in each scope: <%= link_to a.place.name, **a.place**( :id => a.place.friendly_id ) %> the marked a.place is the spot, that produces these extra queries.

• How to perform Rails model validation checks within model but outside of filters using ledermann-rails-settings and extensions

  - by user1277160

  Background I'm using ledermann-rails-settings (https://github.com/ledermann/rails-settings) on a Rails 2/3 project to extend virtually the model with certain attributes that don't necessarily need to be placed into the DB in a wide table and it's working out swimmingly for our needs. An additional reason I chose this Gem is because of the post How to create a form for the rails-settings plugin which ties ledermann-rails-settings more closely to the model for the purpose of clean form_for usage for administrator GUI support. It's a perfect solution for addressing form_for support although... Something that I'm running into now though is properly validating the dynamic getters/setters before being passed to the ledermann-rails-settings module. At the moment they are saved immediately, regardless if the model validation has actually fired - I can see through script/console that validation errors are being raised. Example For instance I would like to validate that the attribute :foo is within the range of 0..100 for decimal usage (or even a regex). I've found that with the previous post that I can use standard Rails validators (surprise, surprise) but I want to halt on actually saving any values until those are addressed - ensure that the user of the GUI has given 61.43 as a numerical value. The following code has been borrowed from the quoted post. class User < ActiveRecord::Base has_settings validates_inclusion_of :foo, :in => 0..100 def self.settings_attr_accessor(*args) >>SOME SORT OF UNLESS MODEL.VALID? CHECK HERE args.each do |method_name| eval " def #{method_name} self.settings.send(:#{method_name}) end def #{method_name}=(value) self.settings.send(:#{method_name}=, value) end " end >>END UNLESS end settings_attr_accessor :foo end Anyone have any thoughts here on pulling the state of the model at this point outside of having to put this into a before filter? The goal here is to be able to use the standard validations and avoid rolling custom validation checks for each new settings_attr_accessor that is added. Thanks!

• Using Routing helpers in a Rake task

  - by trobrock

  I have a rake task that sends out the next 'x' invitations to join a beta it uses this code: desc "This will send out the next batch of invites for the beta" task :send_invites => :environment do limit = ENV['limit'] c = 0 invitation = Invitation.all(:conditions => { :sent_at => nil, :sender_id => nil }, :limit => limit).each do |i| Mailer.deliver_invitation(i, register_url(i.token)) c.increment! end puts "Sent #{c} invitations." end I need to pass in the 'register_url' to the Mailer in order for the link to show up in the email, but since this is running from a rake task and not from a request it does not have a access to the helper methods. What is the best way of achieving this?

• Validate HAML from ActiveRecord: scope/controller/helpers for link_to etc?

  - by Chris Boyle

  I like HAML. So much, in fact, that in my first Rails app, which is the usual blog/CMS thing, I want to render the body of my Page model using HAML. So here is app/views/pages/_body.html.haml: .entry-content= Haml::Engine.new(body, :format => :html5).render ...and it works (yay, recursion). What I'd like to do is validate the HAML in the body when creating or updating a Page. I can almost do that, but I'm stuck on the scope argument to render. I have this in app/models/page.rb: validates_each :body do |record, attr, value| begin Haml::Engine.new(value, :format => :html5).render(record) rescue Exception => e record.errors.add attr, "line #{(e.respond_to? :line) && e.line || 'unknown'}: #{e.message}" end end You can see I'm passing record, which is a Page, but even that doesn't have a controller, and in particular doesn't have any helpers like link_to, so as soon as a Page uses any of that it's going to fail to validate even when it would actually render just fine. So I guess I need a controller as scope for this, but accessing that from here in the model (where the validator is) is a big MVC no-no, and as such I don't think Rails gives me a way to do it. (I mean, I suppose I could stash a controller in some singleton somewhere or something, but... excuse me while I throw up.) What's the least ugly way to properly validate HAML in an ActiveRecord validator?

• How to let a guest user start their workflow and prompt registration when they try to save their wor

  - by Brandon Cordell

  I'm wondering what I would do to go about letting a guest use my web application without registering, then if they attempt to save their work they are prompted with a registration. This will be in a rails application by the way. Can I just allow public access to part of the work flow, then when they save check if they're a registered user (by session value, or cookie?). If they aren't a registered user, save all their work into the session and let them fill out a sign out form. On successful registration automatically log them in and initiate the create on the db?

• Saving an active record, in what order are the associated objects saved?

  - by Bryan

  In rails, when saving an active_record object, its associated objects will be saved as well. But has_one and has_many association have different order in saving objects. I have three simplified models: class Team < ActiveRecord::Base has_many :players has_one :coach end class Player < ActiveRecord::Base belongs_to :team validates_presence_of :team_id end class Coach < ActiveRecord::Base belongs_to :team validates_presence_of :team_id end I expected that when team.save is called, team should be saved before its associated coach and players. I use the following code to test these models: t = Team.new team.coach = Coach.new team.save! team.save! returns true. But in another test: t = Team.new team.players << Player.new team.save! team.save! gives the following error: > ActiveRecord::RecordInvalid: > Validation failed: Players is invalid I figured out that team.save! saves objects in the following order: 1) players, 2) team, and 3) coach. This is why I got the error: When a player is saved, team doesn't yet have a id, so validates_presence_of :team_id fails in player. Can someone explain to me why objects are saved in this order? This seems not logical to me.

• Rails SSL Requirement plugin -- shouldn't it check to see if you're in production mode before redire

  - by Joe Van Dyk

  Take a look at the ssl_requirement plugin. Shouldn't it check to see if you're in production mode? We're seeing a redirect to https in development mode, which seems odd. Or is that the normal behavior for the plugin? I thought it behaved differently in the past.

• How do I configure integration tests using rspec 2?

  - by Jamie Monserrate

  I need to have different settings for my unit tests and different settings for my integration tests. Example For unit tests, I would like to do WebMock.disable_net_connect!(:allow_localhost => true) And for integration tests, I would like to do WebMock.allow_net_connect! Also, before the start of an integration test, I would like to make sure that solr is started. Hence I want to be able to call config.before(:suite) do SunspotStarter.start end BUT, only for integration tests. I do not want to start my solr if its a unit test. How do I keep their configurations separate? Right now, I have solved this by keeping my integration tests in a folder outside the spec folder, which has its own spec_helper. Is there any better way?

• Rails and SWFUpload: Sporadic Failure on Upload and Response Issue

  - by Gimli

  I've got SWFUpload version 2.5 beta 3 attached to my Rails 2.3.2 application and it works great 75% of the time. The other 25%, I get types of failure. The first failure is a failure to upload. The activity starts, but never actually sends the file to the servers. In my JS, when setting breakpoints, it stops between setting the post params and starting the upload (last two lines below): var params = { "authenticity_token": authToken, "photo[name]": $("#photo_name").val(), "photo[description]": $("#photo_description").val(), "photo[post_id]": $("#post_id").val() }; params[keyName] = key; swfu.setPostParams(params); swfu.startUpload(); It just occurred to me that the file might not being queued, but I've got a handler attached to show the file name in a text box and that works consistently. The second issue is this: Sometimes the response string is truncated. I'm rendering a partial in Rails without a layout to show the uploaded file data in my layout. Most of the time this partial comes through fine, but sometimes it comes through as only the first line, or only parts of the first several lines. The variables seem to be coming through into the view just fine. Any ideas? Thanks!

• Easiest way to split up a large controller file

  I have a rails controller file that is too large (~900 lines - api_controller). I'd like to just split it up like something like this: api_controller.rb api_controller_item_admin.rb api_controller_web.rb I don't want to split into multiple controllers. What would be the preferred way to do this? Could I just require the new parts at the end? like: require './api_controller_item_admin' require './api_controller_web'

• How do I find the .max of an attribute value among a group of different Models?

  - by Angela

  Hi, everyone: I am also open to just straight-up refactoring what I'm finding to be pretty repetitive, but to give a baseline of how it's working.... I have for every contact a Campaign, which has_many of three types of Models: Email, Call, and Letter. When an Email (Call or Letter) has been executed for a specific contact, I have a Contact_Email(_or_Call_or_Letter) which belongs to both the Contact and the Model (Email_or_Call_or_Letter). Each Contact_Email for example pairing has a :date_sent attribute. So does each Contact_Call and Contact_Letter. How do I find the latest of all of them? Here is the code I wrote that can find the latest Email and my finding retyping similar code for Call and Letter, but then stuck on how to do a .max on all of them: def last_email(contact) #get campaign the contact belongs to @campaign = Campaign.find_by_id(contact.campaign_id) @last_email = ContactEmail.find(:last, :conditions => "contact_id = #{contact.id}", :order => "date_sent DESC") @last_call = ContactCall.find(:last, :conditions => "contact_id = #{contact.id}", :order => "date_sent DESC") @last_letter = ContactLetter.find(:last, :conditions => "contact_id = #{contact.id}", :order => "date_sent DESC") # how do I get the latest of all of these to display? if @last_sent_email.nil? return "no email sent" else return @last_sent_email.date_sent end end Question 1: With what I have, how can I find effectively @last_event given I can find the last Email, last Call, and last Letter for every contact? Question 2: How can I remove the repetitive code that I have to write for each Model?

• Can't mass-assign protected attributes -- unsolved issue

  - by nfriend21

  I have read about 10 different posts here about this problem, and I have tried every single one and the error will not go away.
