  • Escape doube and single backslashes in a string in Ruby

    - by Nick Gorbikoff
    Hello. I'm trying to access a network path in my ruby script on a windows platform in a format like this. \\servername\some windows share\folder 1\folder2\ Now If I try to use this as a path, it won't work. Single backslashes are not properly escaped for this script. path = "\\servername\some windows share\folder 1\folder2\" d = Dir.new(path) I tried everything I could think of to properly escape slashes in the path. However I can't escape that single backslash - because of it's special meaning. I tried single quotes, double quotes, escaping backslash itself, using alternate quotes such as %Q{} or %q{}, using ascii to char conversion. Nothing works in a sense that I'm not doing it right. :-) Right now the temp solution is to Map a network drive N:\ pointing to that path and access it that way, but that not a solution. Does anyone have any idea how to properly escape single backslashes? Thank you

  • 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. So here goes: I am trying to have a nested form on my users/new page, where it accepts user-attributes and also company-attributes. When you submit the form: Here's what my error message reads: ActiveModel::MassAssignmentSecurity::Error in UsersController#create Can't mass-assign protected attributes: companies app/controllers/users_controller.rb:12:in `create' Here's the code for my form: <%= form_for @user do |f| %> <%= render 'shared/error_messages', object: f.object %> <%= f.fields_for :companies do |c| %> <%= c.label :name, "Company Name"%> <%= c.text_field :name %> <% end %> <%= f.label :name %> <%= f.text_field :name %> <%= f.label :email %> <%= f.text_field :email %> <%= f.label :password %> <%= f.password_field :password %> <%= f.label :password_confirmation %> <%= f.password_field :password_confirmation %> <br> <% if current_page?(signup_path) %> <%= f.submit "Sign Up", class: "btn btn-large btn-primary" %> Or, <%= link_to "Login", login_path %> <% else %> <%= f.submit "Update User", class: "btn btn-large btn-primary" %> <% end %> <% end %> Users Controller: class UsersController < ApplicationController def index @user = User.all end def new @user = User.new end def create @user = User.create(params[:user]) if @user.save session[:user_id] = @user.id #once user account has been created, a session is not automatically created.

  • link_to for calling an action, instead of a button_to

    - by Brian Roisentul
    I'd like to call an action with a link_to button without being redirected to another page(I don't want ajax). For you to have an idea, I'm trying to accomplish a sort "link button" in a search page. So, when the link is clicked, the page should be refreshed showing the list ordered as I tell it in the action. If I do the following in my view, it will ask me for a template called as the action, and I don't want it: <%= link_to 'M&Aacute;S RELEVANTES', search_filter_relevance_path %> My routes file looks like this: map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance' And my controller looks like this(I haven't developed the functionality yet): def search_filter_relevance end Any help on this will be appreciated.

    I'm using a partial from my messages controller in my tags controller. The portion in question looks like this: <% unless message.tag_list.nil? || message.tag_list.empty? %> <% message.tags.each do |t| %> <div class="tag"><%= link_to t.name.titleize, tag_path(t) %></div> <% end %> <% end %> Is there a way to hide this portion of the partial only when it is viewed from the tags controller?

  • Can I combine atom feeds from seperate resources into one?

    - by stephemurdoch
    I have two resource for which I would like to generate feeds; they are called podcasts and posts. The problem is that when I include the auto_discovery_link in my templates, I have to add one for each of the two atom feeds that I've generated. The reason why this is a problem is that there are now two feeds for users to choose from, and most people probably won't realise that they need both so will only pick one. Is there a way to combine atom feeds from different resources into one atom feed? Like application.atom or something? I'm using builder to generate the feed.

  • Creating an additional related model with Devise

    - by Tim Sullivan
    I've started to implement a new project using Devise, which is pretty fantastic for handling users. However, when a user signs up, they're not just creating a User model, but also need to create a related Account model that represents the company. Additional users will also belongs_to this Account model. I can't seem to find a hook for this in Devise, though it seems like a pretty common pattern. What's the best practice for this?

  • ActiveRecord field normalization

    - by Bill
    I feel bad asking this question, as I thought I knew enough about Activerecord to answer this myslef. But such is the way of having SO available ... I'm trying to remove the commas from a field in a model of mine, I want the user to be able to type a number , ie 10,000 and that number be stored in the database as 10000. I was hoping that I could do some model-side normalization to remove the comma. I don't want to depend on the view or controller to properly format my data. I tried ; before_validation :normalize def normalize self['thenumber'] = self['thenumber'].to_s.gsub(',','') end no worky :(

  • Nokogiri Truncating XML Input

    - by bdorry
    I am having issues with a colleagues machine truncating XML while using Nokogiri to parse a Media RSS feed. The feed is a standard Media RSS feed, and the XML is not malformed. It looks like it simply stops at a certain point in the XML and closes any tags that would have been open at that current point in the document. (Unfortunately I do not have the XML avialable to me right now, but I will update this question with the actual XML when I have it available to me). My confusion comes from it working fine on my machine (OSX 10.6, Nokogiri 1.4.4) while it in correctly on his machine using the same setup - however his machine is a few years older. I imagine that there is a difference somewhere but unfortunately I don't know what to look for. Any thoughts or direction would be greatly appreciated.

  • Redirects in RoR: Which one to use out of redirect_to and head :moved_permanently?

    - by scrr
    Hello, we are making a website that takes a generated incoming link and forwards the user who is clicking on it to another website while saving a record of the action in our DB. I guess it's basically what ad-services like AdSense do. However, what is the best way to redirect the user? I think html-meta-tag-redirects are out of question. So what other options are there? head :moved_permanently, :location => "http://www.domain.com/" This one is a 301-redirect. The next one is a 302: redirect_to "http://www.domain.com" Are there any others? And which is best to use for our case? The links are highly-dynamic and change all the time. We want to make sure we don't violate any existing standards and of course we don't want search-engines to tag us as spammers (which we are not, btw). Thanks!

  • Array::include? on ActiveRecord collection not calling op== ?

    - by tribalvibes
    Given a collection of named Foos from ActiveRecord, why does Array.include? not seem to call Foo.== but yet index does? class Foo < ActiveRecord::Base def ==(s) self.name == s end end class Bar < ActiveRecord::Base has_many :foos end bar.foos << Foo.new( :name = 'hmm' ) bar.foos.all.include?('hmm') # does select all from db every time = true bar.foos.include?('hmm') # does not go to db, but does not find the Foo! = false bar.foos.index('hmm') # does not go to db, but does find the Foo[0] ! = 0 bar.foos.index('eh') # no such object = nil I understand shallow about the proxies, but (without a detour into the AR source) why is index seemingly behaving correctly but include? is not !? Is this a bug in the proxy behavior, and/or is this behavior documented somewhere ? Thanks.

  • Why is YAML installing to my home directory instead of its proper directory?

    - by Zack Shapiro
    I keep getting the following error when installing Ruby 1.9.3-p125: It seems your ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml and reinstall your ruby. I've tried installing LibYAML and for some reason it's installing in my home directory on OS X Lion where the Documents, Music, Pictures, etc. folders are. Any idea how I can get rid of this error, properly install YAML and never have to deal with this again?

  • Overriding rubies spaceship operator <=>

    - by ericsteen1
    I am trying to override rubies <= (spaceship) operator to sort apples and oranges so that apples come first sorted by weight, and oranges second, sorted by sweetness. Like so: module Fruity attr_accessor :weight, :sweetness def <=>(other) # use Array#<=> to compare the attributes [self.weight, self.sweetness] <=> [other.weight, other.sweetness] end include Comparable end class Apple include Fruity def initialize(w) self.weight = w end end class Orange include Fruity def initialize(s) self.sweetness = s end end fruits = [Apple.new(2),Orange.new(4),Apple.new(6),Orange.new(9),Apple.new(1),Orange.new(22)] p fruits #should work? p fruits.sort But this does not work, can someone tell what I am doing wrong here, or a better way to do this?

Is testing for AR associations really required ?
