  • Rails Functional test assert_select javascript respond_to

    - by Macint
    Hello, I am currently trying to write functional tests for a charging form which gets loaded on to the page via AJAX(jQuery). It loads the form from the charge_form action which returns the consult_form.js.erb view. This all works, but I am having trouble with my testing. In the functional I can go to the action but I cannot use assert_select to find a an element and verify that the form is in fact there. Error: 1) Failure: test_should_create_new_consult(ConsultsControllerTest) [/test/functional/consults_controller_test.rb:8]: Expected at least 1 element matching "h4", found 0. <false> is not true. This is the view. consult_form.js.erb: <div id="charging_form"> <h4>Charging form</h4> <div class="left" id="charge_selection"> <%= select_tag("select_category", options_from_collection_for_select(@categories, :id, :name)) %><br/> ... consults_controller_test.rb: require 'test_helper' class ConsultsControllerTest < ActionController::TestCase def test_should_create_new_consult get_with_user :charge_form, :animal_id => animals(:one), :id => consults(:one), :format => 'js' assert_response :success assert_select 'h4', "Charging form" #can't find h4 end end Is there a problem with using assert_select with types other than html? Thank you for any help!

  • How to override 'where' in rails 3

    - by Zakwan Alhajjar
    I have upgraded my application from rails 2.3.8 to 3.0.3 . But I'm facing a problem. I was using 'find' but the overriding doesn't work in rails 3: # override activerecord's find to allow us to find by name or id transparently def self.find(*args) if args.is_a?(Array) and args.first.is_a?(String) and (args.first.index(/[a-zA-Z\-_]+/) or args.first.to_i.eql?(0) ) find_by_login_slug(args) else super end end I'm wondering if there is a way to make this work in rails 3 or even by using where instead. thanks

  • Contents of a node in Nokogiri

    - by Styggentorsken
    Is there a way to select all the contents of a node in Nokogiri? <root> <element>this is <hi>the content</hi> of my æøå element</element> </root> The result of getting the content of /root/element should be this is <hi>the content</hi> of my æøå element Edit: It seems like the solution is simply to use myElement.inner_html(). The problem I had was in fact that I was relying on an old version of libxml2, which escaped all the special characters.

  • Rails - single ID for multiple models

    - by user352351
    I'm building an app which will allow a user to scan the barcode on a 'shelf', 'box' or 'product' which will then bring up that particular item or all the associated items. As these are all separate models with their own ID's, I need a global ID table. I was thinking of a polymorphic table called 'barcodes' barcodes id barcode_number barcodable Is there an easy way to do this? Or is polymorphic the best way?

  • session[:key] = value doesn't work

    - by Bill Leeper
    I am trying to make use of session data in my application and for some reason I don't have something setup right. The code: session[:key] = some_value Generates the following error: The error occurred while evaluating nil.[] Other controllers don't have an issue with the session, so I am guessing I missed some basic configuration thing somewhere.

  • Problem building relationships between models

    - by Brian Roisentul
    Until now, I've been using acts_as_taggable_on plugin for tagging announcements. That plugin creates the following tables: taggings: relates tags and announcements table(for the tagged item, it has a field called taggable_id, which I rename to "announcement_id" for what I'll explain below). tags: has the tag ids and names. The other day, I discovered that I had no way of getting the announcements tagged with a certain tag, but doing Announcement.tagged_with(tag_name), and I don't want to search by name, but for id. So, as I'm using almost nothing of the functionality in that plugin, I decided to create the models for taggings and tags tables, to accomplish this: Announcement.tags. The models' relationships look as following: class Tagging < ActiveRecord::Base belongs_to :announcement belongs_to :tag end class Tag < ActiveRecord::Base has_many :announcements, :through => :taggings end class Announcement < ActiveRecord::Base has_many :tags, :through => :taggings Why can't I execute the command Announcement.tags? Because when I try, I get undefined method `tags'

  • validates_associated not honoring :if

    - by James Ferguson
    I'm totally blocked on this. See this pastie for sample code: http://pastie.org/990040 The first test will fail. The user model validates an associated address model, but is only supposed to do it if a flag is true. In practice it does it all the time. What is going on?

  • No route matches - after login attempt - even though the route exists?

    - by datorum
    I am working on a rails application and added a simple login system according to a book. I created the controller admin: rails generate controller admin login logout index It added the following routes to routes.db get "admin/login" get "admin/logout" get "admin/index" I can got to http://localhost:3000/admin/login there is no problem at all. But when I try to login I get: No route matches "/admin/login"! Now, the first confusing part is that the "login" method of my AdminController is not executed at all. The second confusing part is that this code works like a charm - redirects everything to /admin/login: def authorize unless User.find_by_id(session[:user_id]) flash[:notice] = "you need to login" redirect_to :controller => 'admin', :action => 'login' end end Sidenotes: I restarted the server several times. I tried a different browser - to be sure there is no caching problem.

  • Rails 3 does not render HTML as markup

    Hello, Stackoverflow.

Or I just have to convert the < and > by Javascript? Thank you :)

  • Running a loop (such as one for a mock webserver) within a thread

    - by bob c
    I'm trying to run a mock webserver within a thread within a class. I've tried passing the class' @server property to the thread block but as soon as I try to do server.accept the thread stops. Is there some way to make this work? I want to basically be able to run a webserver off of this script while still taking user input via stdin.gets. Is this possible? class Server def initialize() @server = TCPServer.new(8080) end def run() @thread = Thread.new(@server) { |server| while true newsock = server.accept puts "some stuff after accept!" next if !newsock # some other stuff end } end end def processCommand() # some user commands here end test = Server.new while true do processCommand(STDIN.gets) end In the above sample, the thread dies on server.accept

  • rails log rotation behaves weird (rails version 2.3.5)

    - by robodo
    I'm trying to setup log rotation in rails. I have put this in my environment/development.rb: config.logger = Logger.new("#{RAILS_ROOT}/log/#{ENV['RAILS_ENV']}.log", 1, 5*1048576) 2 files are created :-) but it looks like rails is writing to them randomly and at the same time as well. This creates messy log files :-( what am I missing?

  • Multiple controllers with a single model

    - by Eric K
    I'm setting up a directory application for which I need to have two separate interfaces for the same Users table. Basically, administrators use the Users controller and views to list, edit, and add users, while non-admins need a separate interface which lists users in a completely different manner. To do this, would I be able to just set up another controller with different views but which accesses the Users model? Sorry if this is a simple question, but I've had a hard time finding how to do this.

  • Can I use a method as a lambda?

    - by NewAlexandria
    I have an interface the defines a group of conditions. it is one of several such interfaces that will live with other models. These conditions will be called by a message queue handler to determine completeness of an alert. All the alert calls will be the same, and so I seek to DRY up the enqueue calls a bit, by abstracting the the conditions into their own methods (i question if methods is the right technique). I think that by doing this I will be able to test each of these conditions. class Loan module AlertTriggers def self.included(base) base.extend LifecycleScopeEnqueues # this isn't right Loan::AlertTriggers::LifecycleScopeEnqueues.instance_method.each do |cond| class << self def self.cond ::AlertHandler.enqueue_alerts( {:trigger => Loan.new}, cond ) end end end end end module LifecycleScopeEnqueues def student_awaiting_cosigner lambda { |interval, send_limit, excluding| excluding ||= '' Loan.awaiting_cosigner. where('loans.id not in (?)', excluding.map(&:id) ). joins(:petitions). where('petitions.updated_at > ?', interval.days.ago). where('petitions.updated_at <= ?', send_limit.days.ago) } end end I've considered alternatives, where each of these methods act like a scope. Down that road, I'm not sure how to have AlertHandler be the source of interval, send_limit, and excluding, which it passes to the block/proc when calling it.

  • Clarifying... So Background Jobs don't Tie Up Application Resources (in Rails)?

    - by viatropos
    I'm trying to get a better grasp of the inner workings of background jobs and how they improve performance. I understand that the goal is to have the application return a response to the user as fast as it can, so you don't want to, say, parse a huge feed that would take 10 seconds because it would prevent the application from being able to process any other requests. So it's recommended to put any operations that take more than say 500ms to execute, into a queued background job. What I don't understand is, doesn't that just delay the same problem? I know the user who invoked that background job will get an immediate response, but what if another user comes right when that background job starts (and it takes 10 seconds to finish), wont that user have to wait? Or is the main issue that, requests are the only thing that can happen one-at-a-time, while on the other hand a request can start while one+ background jobs are in the middle of running? Is that correct?

  • has_many through and saving to join table

    - by Paul
    I have the following: class Invite < ActiveRecord::Base belongs_to :user has_many :invite_recipients has_many :recipients, :through => :invite_recipients end class InviteRecipient < ActiveRecord::Base belongs_to :invite belongs_to :user_comm validates_associated :user_comm, :invite validates_uniqueness_of :user_comm_id, :scope => :invite_id end class UserComm < ActiveRecord::Base end I'd like to create a method for Invite with invite_text and a list of UserComms as the variables and then have it create a new invite with the following validations: 1. All UserComms are unique 2. The invite isn't saved unless all the associated InviteRecipients are saved as well (in other words, the invite isn't valid unless all the created InviteRecipients are valid) I'm not familiar with how to create model functions. Moreover, when I try something like this: i = Invite.new(:invite_text => 'come join') ir1 = InviteRecipient.new(:invite => i, :user_comm => user_comm1) ir2 = InviteRecipient.new(:invite => i, :user_comm => user_comm2) i.invite_recipients = [uc1, uc2] i.save! I get: SystemStackError: stack level too deep

  • How to detect if an element exists in Watir

    - by Rijksband
    Hi, I'm relatively new to Watir but can find no good documentation (examples) regarding how to check if an element exists. There are the API specs, of course, but these make precious little sense to me if I don't find an example. I've tried both combinations but nothing seems to work... if browser.image (:src "/media/images/icons/reviewertools/editreview.jpg").exists then... if browser.image (:src "/media/images/icons/reviewertools/editreview.jpg").exists? then... If anyone has a concrete suggestion as per how to implement this, please help! Thanks!

  • nested has_many

    - by Nick Vanderbilt
    I am using Rails 2.3.5. Class User < ActiveRecord::Base has_many :phones end class Phone < ActiveRecord::Base has_many :frequency_bands end I want to get all the frequency_bands for a user. I know I can write a method def freq_bands for User but I would like to know if it is possible to have has_many freq_bands for a User. In this way I can chain the call. What I would like to have is class User < ActiveRecor::Base has_many :frequence_bands, :through => phones end I think it is possible to have nested has_many using this plugin http://github.com/ianwhite/nested_has_many_through However if possible I would like to avoid using another plugin and rely solely on rails.

  • How to exclude an array of ids from query in Rails (using ActiveRecord)?

    - by CuriousYogurt
    I would like to perform an ActiveRecord query that returns all records except those records that have certain ids. The ids I would like excluded are stored in an array. So: ids_to_exclude = [1,2,3] array_without_excluded_ids = Item. ??? I'm not sure how to complete the second line. Background: What I've already tried: I'm not sure background is necessary, but I've already tried various combinations of .find and .where. For example: array_without_excluded_ids = Item.find(:all, :conditions => { "id not IN (?)", ids_to_exclude }) array_without_excluded_ids = Item.where( "items.id not IN ?", ids_to_exclude) These fail. This tip might be on the right track, but I have not succeeded in adapting it. Any help would be greatly appreciated.

  • Click to select from a list of tags in jQuery

    - by Michael Doornbos
    I'm struggling to find a tag selection UI for a rails app. Ideally it would be something like the selection here on Stackoverflow, or on Delicious or Digg. I want users to be able to select multiple tags with a single click. We're already using jQuery, so it makes sense to use something that takes advantage of that. I've used the selection ui in jQuery and I'm not thrilled about having users need to hold down ctrl to select multiple tags.
