  • Passing value from :locals to link_remote_to

    - by Teef L
    In my edit.haml file, I have =render :partial => 'old_question_tags', :locals => {:current_question => @question.id}. I'd like to pass the value in :current_question to a link_to_remote call in _old_question_tags.haml: #{link_to_remote image_tag('red-x.png', {:alt => "Remove #{t.name} tag"}), :url => {:action => 'remove_old_tag_from_question', :tag_remove => t.id, :current_question => current_question}} But I get this error on the link_to_remote line: ActionView::TemplateError (undefined local variable or method `current_question' for #<ActionView::Base:0xdb2fec8>) In _old_question_tags.haml, if I just print current_question (using =current_question), it prints the number without any problems. How do I properly pass that value to the partial so that I can pass it to the link_to_remote call?

  • Sorcery/Capybara: Cannon log in with :js => true

    - by PlankTon
    I've been using capybara for a while, but I'm new to sorcery. I have a very odd problem whereby if I run the specs without Capybara's :js = true functionality I can log in fine, but if I try to specify :js = true on a spec, username/password cannot be found. Here's the authentication macro: module AuthenticationMacros def sign_in user = FactoryGirl.create(:user) user.activate! visit new_sessions_path fill_in 'Email Address', :with => user.email fill_in 'Password', :with => 'foobar' click_button 'Sign In' user end end Which is called in specs like this: feature "project setup" do include AuthenticationMacros background do sign_in end scenario "creating a project" do "my spec here" end The above code works fine. However, IF I change the scenario spec from (in this case) scenario "adding questions to a project" do to scenario "adding questions to a project", :js => true do login fails with an 'incorrect username/password' combination. Literally the only change is that :js = true. I'm using the default capybara javascript driver. (Loads up Firefox) Any ideas what could be going on here? I'm completely stumped. I'm using Capybara 2.0.1, Sorcery 0.7.13. There is no javascript on the sign in page and save_and_open_page before clicking 'sign in' confirms that the correct details are entered into the username/password fields. Any suggestions really appreciated - I'm at a loss.

    I have model Article it has field title with some text that may contain some "magic" patterns.

  • RoR Server won't detach with -d option

    - by Rodrigo
    I had to reinstall a bunch of my port installs the other day and now when I launch my RoR server with "ruby script/server -d -p 3000" the server wont work. I am not seeing any errors in the logs. If I start it with "ruby script/server -p 3000" it works fine. Any ideas of what I might have uninstalled that would cause this behavior?

  • Preventing ActiveRecord save() on an instance

    - by Craig Walker
    I have an ActiveRecord model object Foo; it represents a standard database row. I want to be able to display modified versions of instances of this object. I'd like to reuse the class itself, as it already has all the hooks & aspects I'll need. (For example: I already have a view that displays the appropriate attributes). Basically I want to clone the model instance, modify some of its properties, and feed it back to the caller (view, test, etc). I do not want these attribute modifications getting back into the database. However, I do want to include the id attribute in the cloned version, as it makes dealing with the route-helpers much easier. Thus, I plan on calling ActiveRecord::Base.clone(), manually setting the ID of the cloned instance, and then making the appropriate attribute changes to the new instance. This has me worried though; one save() on the modified instance and my original data will get clobbered. So, I'm looking to lock down the new instance so that it won't hurt anything else. I'm already planning on calling freeze() (on the understanding that this prevents further modification to the object, though the documentation isn't terribly clear). However, I don't see any obvious way to prevent a save(). What would be the best approach to achieving this?

  • Why would paperclip not assign an ID to my uploaded photos?

    - by Trip
    I just deployed to a cluster server, and my delayed_jobs recipe was overwritten in the process. I solved that, delayed_jobs is up and running but can't find the ID of images that are uploaded.

Anyone know where I could poke and pry from here? UPDATE: I created a clone application on a single server. And there are no problems. The images on the cluster do show up (occassionally). If I keep clicking on the folders that lead to photos, it will 50% of the time return a 404 with it not being able to find the photo, and the other half it will present the photo. So the problem has got to be with the server interaction between the ActiveRecord through multiple servers.

  • Customizing the Stars Image for Ajaxful_Rating RoR plugin

    - by Kevin
    I'm trying to come up with my own star image that's slightly smaller and different style than the one provided in the gem/plugin, but Ajaxful_rating doesn't have an easy way to do this. Here's what I've figured out so far: The stars.png in the public folder is three 25x25 pixel tiles stacked vertically, ordered empty star, normal star, and hover star. I'm assuming as long as you keep the above constraints, you should be fine without modifying any other files. But what if you want to change the image size of the stars to larger or smaller? I've found where you can change the height in the stylesheets/ajaxful_rating.css .ajaxful-rating{ position: relative; /*width: 125px; this is setted dynamically */ height: 25px; overflow: hidden; list-style: none; margin: 0; padding: 0; background-position: left top; } .ajaxful-rating li{ display: inline; } .ajaxful-rating a, .ajaxful-rating span, .ajaxful-rating .show-value{ position: absolute; top: 0; left: 0; text-indent: -1000em; height: 25px; line-height: 25px; outline: none; overflow: hidden; border: none; } You just need to change every place that says "25px" above to whatever height your new star image is. This works fine but doesn't display the horizontal part correctly. Anyone know where I would look to set the horizontal part as well? (I'm assuming it's in an .rb file somewhere based upon how many stars you specified in your ajaxful_rating setup)

  • dynamic searchable fields, best practice?

    - by boblu
    I have a Lexicon model, and I want user to be able to create dynamic feature to every lexicon. And I have a complicate search interface that let user search on every single feature (including the dynamic ones) belonged to Lexicon model. I could have used a serialized text field to save all the dynamic information if they are not for searching. In case I want to let user search on all fields, I have created a DynamicField Model to hold all dynamically created features. But imagine I have 1,000,000,000 lexicon, and if one create a dynamic feature for every lexicon, this will result creating 1,000,000,000 rows in DynamicField model. So the sql search function will become quite inefficient while a lot of dynamic features created. Is there a better solution for this situation? Which way should I take? searching for a better db design for dynamic fields try to tuning mysql(add cache fields, add index ...) with current db design

  • How do I find where id does not match any of an array?

    - by Nick5a1
    I have a Workout model that has and belongs to many Equipment models. I have an array of some Equipment IDs. I want to find all Workouts that don't have any Equipment assigned that matches any of the array of Equipment IDs. So, if my array = [2,3,5] I want to find all workouts where the assigned equipment ids does not include 2, 3 or 5. EDIT: Workout.joins(:equipment).where("equipment.id not in(?)",[2,3,5]).uniq Assuming five instances of Equipment, the code above returns workouts with equipment.ids 1 and 4 (good), but also returns partial matches for example Workouts with equipment.id = [1,2], [1,2,3].

  • Initialize child models at model creation

    - by Antoine
    I have a model Entree which belongs to a model Vin, which itself belongs to a model Producteur. On the form for Entree creation/edition, I want to allow the user to define the attributes for parent Vin and Producteur to create them, or retrieve them if they exist (retrieval based on user input). For now I do the following in Entree new and edit actions: @entree = Entree.new @entree.vin = Vin.new @entree.vin.producteur = Producteur.new and use fields_for helper in the form,and that works. But I intend to have much more dependencies with more models, so I want to keep it DRY. I defined a after_initialize callback in Vin model which does the producteur initialization: class Vin < ActiveRecord::Base after_initialize :vin_setup def vin_setup producteur = Producteur.new end end and remove the producteur.new from the controller. However, get an error on new action: undefined method `model_name' for NilClass:Class for the line in the form that says <%= fields_for @entree.vin.producteur do |producteur| %> I guess that means the after_initialize callback doesn't act as I expect it. Is there something I'm missing? Also, I get the same error if I define a after_initialize method in the Vin model instead of definiing a callback.

  • Removing a pattern from the beggining and end of a string in ruby

    - by seaneshbaugh
    So I found myself needing to remove <br /> tags from the beginning and end of strings in a project I'm working on. I made a quick little method that does what I need it to do but I'm not convinced it's the best way to go about doing this sort of thing. I suspect there's probably a handy regular expression I can use to do it in only a couple of lines. Here's what I got: def remove_breaks(text) if text != nil and text != "" text.strip! index = text.rindex("<br />") while index != nil and index == text.length - 6 text = text[0, text.length - 6] text.strip! index = text.rindex("<br />") end text.strip! index = text.index("<br />") while index != nil and index == 0 text = test[6, text.length] text.strip! index = text.index("<br />") end end return text end Now the "<br />" could really be anything, and it'd probably be more useful to make a general use function that takes as an argument the string that needs to be stripped from the beginning and end. I'm open to any suggestions on how to make this cleaner because this just seems like it can be improved.

  • Problem with user login validation by authlogic

    - by Andrei
    Hi, I want to use email for signing in, and to allow users to have similar names. One way to do this is to rename login/username field to something different. However, I want to do it just by setting up authlogic. I tried the following acts_as_authentic do |c| c.login_field :email c.validate_login_field false c.validate_email_field true end but it still complains that the login already exists. What must be done to avoid username validation without renaming the field?

  • Best wrapper for simultaneous API requests?

    - by bluebit
    I am looking for the easiest, simplest way to access web APIs that return either JSON or XML, with concurrent requests. For example, I would like to call the twitter search API and return 5 pages of results at the same time (5 requests). The results should ideally be integrated and returned in one array of hashes. I have about 15 APIs that I will be using, and already have code to access them individually (using simple a NET HTTP request) and parse them, but I need to make these requests concurrent in the easiest way possible. Additionally, any error handling for JSON/XML parsing is a bonus.

  • Ordering by Sum from a separate controller part 2

    - by bgadoci
    Ok, so I had this working just fine before making a few controller additions and the relocation of some code. I feel like I am missing something really simple here but have spent hours trying to figure out what is going on. Here is the situation. class Question < ActiveRecord::Base has_many :sites end and class Sites < ActiveRecord::Base belongs_to :questions end I am trying to display my Sites in order of the sum of the 'like' column in the Sites Table. From my previous StackOverflow question I had this working when the partial was being called in the /views/sites/index.html.erb file. I then moved the partial to being called in the /views/questions/show.html.erb file and it successfully displays the Sites but fails to order them as it did when being called from the Sites view. I am calling the partial from the /views/questions/show.html.erb file as follows: <%= render :partial => @question.sites %> and here is the SitesController#index code class SitesController < ApplicationController def index @sites = @question.sites.all(:select => "sites.*, SUM(likes.like) as like_total", :joins => "LEFT JOIN likes AS likes ON likes.site_id = sites.id", :group => "sites.id", :order => "like_total DESC") respond_to do |format| format.html # index.html.erb format.xml { render :xml => @sites } end end

  • Is there a way to undo Mocha stubbing of any_instance?

    - by Steve Weet
    Within my controller specs I am stubbing out valid? for some routing tests, (based on Ryan Bates nifty_scaffold) as follows :- it "create action should render new template when model is invalid" do Company.any_instance.stubs(:valid?).returns(false) post :create response.should render_template(:new) end This is fine when I test the controllers in isolation. I also have the following in my model spec it "is valid with valid attributes" do @company.should be_valid end Again this works fine when tested in isolation. The problem comes if I run spec for both models and controllers. The model test always fails as the valid? method has been stubbed out. Is there a way for me to remove the stubbing of any_instance when the controller test is torn down. I have got around the problem by running the tests in reverse alphabetic sequence to ensure the model tests run before the controllers but I really don't like my tests being sequence dependant.

  • Problem with Juggernaut and transparent wmode in Adobe AIR

    - by vortexmk
    Hi, I am trying to use juggernaut in Adobe AIR application, however the big issue with this is that the juggernaut flash file should have wmode parameter set to 'transparent'. This is a bit of a problem for juggernaut because it seems that it doesn't work with that parameter included. The interesting part is that it is working under Linux on all browsers and in air application, but on Windows it's working only with Safari all other browsers including the AIR application are not even connecting to the juggernaut server. So the question is, what is the cause of this and if anyone had similar problem I would be interested to hear about solutions or workarounds. Thanks, Peco

  • Regular expression in Ruby

    Hi, Could anybody help me make a proper regular expression from a bunch of text in Ruby. I tried a lot but I don't know how to handle variable length titles. The string will be of format <sometext>title:"<actual_title>"<sometext>. I want to extract actual_title from this string. I tried /title:"."/ but it doesnt find any matches as it expects a closing quotation after one variable from opening quotation. I couldn't figure how to make it check for variable length of string. Any help is appreciated. Thanks.

  • Set a datetime for next or previous sunday at specific time

    - by Marc
    I have an app where there is always a current contest (defined by start_date and end_date datetime). I have the following code in the application_controller.rb as a before_filter. def load_contest @contest_last = Contest.last @contest_last.present? ? @contest_leftover = (@contest_last.end_date.utc - Time.now.utc).to_i : @contest_leftover = 0 if @contest_last.nil? Contest.create(:start_date => Time.now.utc, :end_date => Time.now.utc + 10.minutes) elsif @contest_leftover < 0 @winner = Organization.order('votes_count DESC').first @contest_last.update_attributes!(:organization_id => @winner.id, :winner_votes => @winner.votes_count) if @winner.present? Organization.update_all(:votes_count => 0) Contest.create(:start_date => @contest_last.end_date.utc, :end_date => Time.now.utc + 10.minutes) end end My questions: 1) I would like to change the :end_date to something that signifies next Sunday at a certain time (eg. next Sunday at 8pm). Similarly, I could then set the :start_date to to the previous Sunday at a certain time. I saw that there is a sunday() class (http://api.rubyonrails.org/classes/Time.html#method-i-sunday), but not sure how to specify a certain time on that day. 2) For this situation of always wanting the current contest, is there a better way of loading it in the app? Would caching it be better and then reloading if a new one is created? Not sure how this would be done, but seems to be more efficient. Thanks!
