• Route alias, is it possible?

  - by benoror

  I have a Vehicle model: map.resources :vehicles, :has_many => :suppliers Everything works great, but Vehicle has a boolean attribute is_truck. I want to make an Alias so I can get the same resources but with the "truck" word, I tried with: map.trucks '/trucks', :controller => :vehicles, :action => :index, :is_truck => true map.trucks '/trucks/by_supplier/:supplier', :controller => :vehicles, :action => :index, :is_truck => true The first one works well, but when I search within a Form the second doesn't work and searches all suppliers. Is it possible to map.resources for an alias ?

• Unknown user 'app' with capistrano

  - by trobrock

  This is my first time trying to set up capistrano to deploy a rails application. I am deploying from my local machine to my remote server that has the repo, web, app, and mysql servers all on the same machine. I am following this walk through: http://www.capify.org/index.php/From_The_Beginning I get to the command cap deploy:start Then I get this error: *** [err :: example.com] sudo: unknown user: app command finished failed: "sh -c 'cd /var/www/example/current && sudo -p '\\''sudo password: '\\'' -u app nohup script/spin'" on example.com Am I supposed to add an 'app' user, or is there a way of changing what user the command runs as? This is my deploy.rb: set :application, "example" set :repository, "[email protected]:example.git" set :user, "trobrock" set :branch, 'master' set :deploy_to, "/var/www/example" set :scm, :git # Or: `accurev`, `bzr`, `cvs`, `darcs`, `git`, `mercurial`, `perforce`, `subversion` or `none` role :web, "example.com" # Your HTTP server, Apache/etc role :app, "example.com" # This may be the same as your `Web` server role :db, "example.com", :primary => true # This is where Rails migrations will run And obviously everywhere it says example.com is my servers hostname and every it just says example is the app name.

• Rail plugin acts_as_taggable_on :through

  - by Craig

  I have two models: class Employee < ActiveRecord::Base has_many :projects end class Project < ActiveRecord::Base acts_as_taggable_on :skills, :roles end I would like to find Employees using the tags associated with their projects. The geokit-rails plugin supports a similar concept, using its ':through' relationship. Ideally, I would be able to: specify which tags (i.e. skills, roles) would be included in the conditions order the employees by the total number of projects with matching tags be able to access the matching-tag count for each employee for the purposes of building a tag cloud Any thoughts would be appreciated.

• google oauth doesn't redirect to callback after authorization

  - by dstywho

  I can't seem to get google to redirect to the callback url after obtaining the auth token. By redirecting the user to the following url, the user can click grant or deny access. After that the user clicks on one of the choices, the user is not redirected back to the callback url. https://www.google.com/accounts/OAuthAuthorizeToken?oauth_token=4%2F5ETLZ84rGmRxE_yx0b-_IFDReUxe&oauth_callback=http://blahblahblah.com/user_sessions/create&oauth_version=1.0&hd=default I'm wondering if anyone knows what the problem might be. Also does google require I use something like openssl.

• Converting TrueClass / FalseClass to integer.

  - by Nick Gorbikoff

  Hello. I'm trying to figure out if there is an easy way to do the following short of adding to_i method to TrueClass/FalseClass. Here is a dilemma: I have a boolean field in my rails app - that is obviously stored as Tinyint in mysql. However - I need to generate xml based of the data in mysql and send it to customer - there SOAP service requires the field in question to have 0 or 1 as the value of this field. So at the time of the xml generation I need to convert my False to 0 and my True to 1 ( which is how they are stored in the DB). Since True & False lack to_i method I could write some if statement that generate either 1 or 0 depending on true/false state. However I have about 10 of these indicators and creating and if/else for each is not very DRY. So what you recommend I do? Or I could add a to_i method to the True / False class. But I'm not sure where should I scope it in my rails app? Just inside this particular model or somewhere else?

• acts-as-taggable-on find within specific tag context

  - by user284194

  I have two models (entries and messages) using acts-as-taggable-on for tagging. How do I write a find condition for tagged messages from only the one model and not both? The only way I can get the tagged items to display is through the basic find: @tags = Tag.find(:all) But this displays tags from both the entries model and the messages model. How can I find the tags from just the messages model? I'm really new to Rails and ActiveRecord finds. I appreciate any help you can offer. Thank you for reading my question.

• Rails: Helpers and Models - where to organize code

  - by Sam

  More and more I'm putting all of my code in models and helpers concerning MVC. However, sometimes I'm not sure where to organize code. Should it go into the model or should it go into a helper. What are the benefits of each. Is one faster or are they the same. I've heard something about all models getting cached so it seems then like that would be a better place to put most of my code. For example here is a scenario that works in a model or in helper: def status if self.purchased "Purcahsed" elsif self.confirmed "Confirmed" elsif self.reserved "Reserved" else "Pending" end end I don't need to save this status as in the database because there are boolean fields for purchased, and confirmed, and reserved. So why put this in a model or why put it into a helper? So I'm not sure of the best practice or benefits gained on putting code into a model or into helper if it can be in both.

• Doing will_paginate pages calculation around a record

  - by Anderson De Andrade

  I'm displaying a list of events. I wanted displayed the page with the events for today by default. That was easy accomplished by: page = number_of_records_before_RECORD / number_of_pages + 1 Now I want to display the first item of today's events as the first item in that page. Maybe there is a way to generate page numbers around a record with negative values to get back.

• Rails - handling global site settings

  - by egarcia

  I'm developing a new rails application which is supposed to be installed several times in order to implement several sites. There are some things, like the "Site Title" or the "Default Number of Items per Page" that clearly belong to a "global settings" table / config file. I've made a list of the things I think I'll need: ActiveRecord model that is capable of: Storing different kinds of data. I suppose this would be accomplished encoding the values on a string on the db, probably with a "type" field. Indexing settings by name Validations based on a "type" attribute (i.e. don't accept invalid dates on "date" settings) Validations based on a allows_nil property. A controller that allows me to change settings via views. I'm pretty sure I could implement this myself, but I'm not willing to reinvent the wheel. I've done some searching, but I could only find rails-settings, which doesn't really serve me: I need a proper model & controller so I can use declarative-authorization, and it does not provide any controller or view facilities. Is there a gem or plugin out there that implements what I want, or any library I should look at? Thanks a lot.

• Invalid AuthenticityToken everywhere

  - by bwizzy

  I have a rails app that I just deployed which is generating Invalid AuthenticityToken errors anywhere a form is submitted. The app uses subdomains as account names and will also eventually allow for a custom domain to be entered. I have an entry in production.rb to allow for cross-domain session handling. The problem is that you can't login / or submit any form because everything raises an Invalid AuthenticityToken error. The issue looks similar but not the same as http://stackoverflow.com/questions/1201901/rails-invalid-authenticity-token-after-deploy plus I'm not using mongrel. I've tried clearing cookies in the browser, and restarting passenger but no luck. Anyone have any ideas? The server is running nginx + passenger 2.3.11, and Rails 2.3.5. #production.rb config.action_controller.session[:domain] = '.domain.com' #environment.rb config.action_controller.session = { :session_key => '_app_session', :secret => '.... nums and chars .....' }

• How do I search for a phrase using search logic?

  - by fivetwentysix

  Imagine case scenario, you have a list of recipes that have ingredients as a text. You want to see how many recipes contain "sesame oil". The problem with default searchlogic searching using Recipe.ingredients_like("sesame oil") is that any recipe with sesame OR oil would come up, when I'm searching for sesame+oil.

• Passing hash as values in hidden_field_tag

  - by funkymunky

  I am trying to pass some filters in my params through a form like so: hidden_field_tag "filters", params[:filters] For some reason the params get changed in the next page. For example, if params[:filters] used to be... "filters"={"name_like_any"=["apple"]} [1] ...it gets changed to... "filters"="{\"name_like_any\"=[\"apple\"]}" [2] note the extra quotations and backslashes in [2] when compared to [1]. Any ideas? I'm attempting to use this with searchlogic for some filtering, but I need it to persist when I change change objects in forms. I would prefer not to have to store it in session.

• How much should I charge for Rails programming?

  - by Oskar Gantt

  I have been asked to quote an hourly rate for freelance programming for a Rails project. Although it would be my first paid project on Rails, I know the technology well from personal projects and have a decade of professional programming experience. This would be my first freelance project ever, so I have no idea how to find out what the going rate for my services should be. Obviously, if I quote a rate that is too high, they may choose someone else - too low and I may feel cheated later on. Any suggestions? Update: I am in NYC and the project is scheduled for 6 months to a year (but this seems unrealistic - I think it will be a multi-year project). I would develop on site (at a corporate location) with one other developer and the project would consist of about 200 custom-built pages initially. 10 hour days with weekends and additional overtime as required. The customer has given no information about how much they will pay - "a competitive rate" - they want me to start the discussion.

• Override Devise Sign-in with reCaptcha

  - by Bashar Abdullah

  I'm trying to override the Rails devise login to include recaptcha. I followed the steps here http://presentations.royvandewater.com/authentication-with-devise.html#8 however for some reason, authentication always fails. To isolate the problem, I removed all my code and called super directly class SessionsController < Devise::SessionsController def create super end end file is at: Rails.root/app/controllers/sessions_controller.rb the slide suggest Rails.root/app/controllers/sessions.rb but I assume that was just a mistake. Trying it out didn't help either. I even copied the full Sessions Controller code into my own, still gives the problem. Authentication fails here specifically: resource = warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#new") Any idea what I might be doing wrong?

• Updating protected using update_all

  - by Jack

  Since you cannot use the normal 'update' and 'update_attribute' methods from ActiveRecord to update a protected attribute, is the following the best way to update an attribute for a single user? User.update_all("admin = true","id = 1") I'm guessing this doesn't lie in the 'best practice' category, so I'm just curious if there is a more appropriate way.

Thank you

• How can I test ActiveRecord::RecordNotFound in my rails app?

  Hi, I have this code in my controller and want to test this code line with a functional test. raise ActiveRecord::RecordNotFound if @post.nil? which assert method should I use? I use the built-in rails 2.3.5 test framework. I tried it with this code: test "should return 404 if page doesn't exist." do get :show, :url => ["nothing", "here"] assert_response :missing end but it doesn't work for me. Got this test output: test_should_return_404_if_page_doesn't_exist.(PageControllerTest): ActiveRecord::RecordNotFound: ActiveRecord::RecordNotFound app/controllers/page_controller.rb:7:in `show' /test/functional/page_controller_test.rb:21:in `test_should_return_404_if_page_doesn't_exist.'

• What's a good plugin or guide I can use to create javascript widgets from a Rails App?

  - by nicosuria

  I've been looking around for a while now and the best guide I've seen so far is Dr Nic's DIY widgets how to (here). I haven't been able to make something like this work: Assuming this is my widget code: <script src="http://mysite/nomnoms.js"> </script> And my nomnoms controller looks like (assume that the list partial exists and simply lists down a link to the show page of each nomnom in the @nomnoms variable): class NomnomsController < ApplicationController def index @nomnoms = Nomnom.find(:all) @content = render_to_string(:partial => 'list') end end And in the index.js of my nomnoms_controller I have: page << "document.write('<div>'" page << "document.write('#{@content.to_json}')" page << "</div>" The above setup doesn't render anything :(. But when I change the second line of index.js to: page << "document.write('nomnoms should be here') ...the widget renders the text. Any help or even a point in the right direction would be greatly appreciated. Thanks in advance.

• Is strftime (hour) showing wrong time?

  - by ander163

  I'm using this line to get the beginning time of the first day of the month. t = Time.now.to_date.beginning_of_month.beginning_of_day When i display this using t.strftime("%A %b %e @ %l:%m %p") it shows: Monday Feb 1 @ 12:02 AM The hour is always 12 (instead of 00), and more wierd the minute changes to match the month in integers. For the February date, it shows 12:02 AM I use .prior_month and .next_month on the variable to move forward or backwards in time. So when I move to June, this would display as Tuesday June 1 @ 12:06 AM But when I just show the value of "t" using a straight t.to_s, I get this time of 00:00:00, which is what I expect: Mon Feb 01 00:00:00 -0700 2010 A similar error occurs using end_of_day, but the hour is always 11 PM and the minute is the same integer value that matches the month in integers, i.e the time is 11:06 PM in June, 11:02 PM in February. Qurky? Admittedly a noob to Rails. Thanks for any comments or explanations.
