  • putting <%=yield %> in a partial for ajax jquery calls

    - by odpogn
    I'm trying to make the "home" link in my <%= render 'layouts/header' %> do an ajax/jquery call to change the <%= yield %> in a partial inside my content div. all i get are blanks in the view.. <%= yield %> works fine when put in a partial without ajax, but it doesn't display anything when using ajax... can yield not be used this way? all I'm really looking for is the ability to click on my sites navigation links without having to reload the entire page... my application.html.erb file looks like so: <head> $(function() { $("#home").live("click", function() { $.get(this.href, null, null, "script"); return false; }); }); </head> <body> <div id="container"> <%= render 'layouts/header' %> <div id="content"> <%= render 'layouts/content' %> </div> <%= render 'layouts/footer' %> </div> </body> my <%= render 'layouts/header' %> contains: <%= link_to "Home", root_path, :id => "home" %> my <%= render 'layouts/content' %> only contains: <%= yield %> home.js.erb $("#content").html("<%= escape_javascript(render("layouts/content")) %>");

  • 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!

  • Rails: generating URLs for actions in JSON response

    - by Chris Butler
    In a view I am generating an HTML canvas of figures based on model data in an app. In the view I am preloading JSON model data in the page like this (to avoid an initial request back): <script type="text/javascript" charset="utf-8"> <% ActiveRecord::Base.include_root_in_json = false -%> var objects = <%= @objects.to_json(:include => :other_objects) %>; ... Based on mouse (or touch) interaction I want to redirect to other parts of my app that are model specific (such as view, edit, delete, etc.). Rather than hard code the URLs in my JavaScript I want to generate them from Rails (which means it always adapts the latest routes). It seems like I have one of three options: Add an empty attr to the model that the controller fills in with the appropriate URL (we don't want to use routes in the model) before the JSON is generated Generate custom JSON where I add the different URLs manually Generate the URL as a template from Rails and replace the IDs in JavaScript as appropriate I am starting to lean towards #1 for ease of implementation and maintainability. Are there any other options that I am missing? Is #1 not the best? Thanks! Chris

  • Form With Quantity doesn't seem to submit

    - by Karl Entwistle
    Hey guys, I've been trying to understand the documentation and find an example, but I'm at a loss. This is just a submit form within the cart for updating the quantity. However, the updated quantity is not getting saved to the database -- it always makes the quantity 0. Please help. Form <% for line_item in @cart.line_items %> <% form_for :lineitems, :url => {:controller => "line_items", :action => "cart_update", :id => "#{line_item.product_id}"} do |l| %> <%= l.text_field :quantity, :size => '3', :value => line_item.quantity %> <%= l.submit 'cart_update' %> <% end %> Route map.connect 'line_item_update', :controller => 'line_items', :action => 'cart_update' Controller def cart_update @product = Product.find(params[:id]) item = LineItem.find_or_create_by_cart_id(:cart_id => current_cart.id, :product_id => @product.id, :quantity => 0, :unit_price => @product.price) item.quantity = (params[:quantity]).to_i item.save redirect_to :controller => 'products' end

  • How to make a control invisible?

    - by Nakilon
    I've made several TextCtrls and Button, but currently users of my application don't want to see them. So I have to hide them temporary (for current build). Here they are: class MainFrame < Wx::Frame def initialize (parent = nil) super nil,:title=>"sometitle",:size=>[600,600] set_sizer Wx::BoxSizer.new Wx::VERTICAL @tag1 = Wx::TextCtrl.new self sizer.add_item @tag1,:flag=>Wx::RIGHT|Wx::EXPAND @tag1.set_value 'property' @tag1title = Wx::TextCtrl.new self sizer.add_item @tag1title,:flag=>Wx::RIGHT|Wx::EXPAND @tag1title.set_value 'title' @tag2 = Wx::TextCtrl.new self sizer.add_item @tag2,:flag=>Wx::RIGHT|Wx::EXPAND @tag2.set_value 'description' @tag2title = Wx::TextCtrl.new self sizer.add_item @tag2title,:flag=>Wx::RIGHT|Wx::EXPAND @tag2title.set_value '' @button_parse = Wx::Button.new self sizer.add_item @button_parse @button_parse.label = "Parse XML" evt_button @button_parse, :click_parse # ...... end # ...... end I see nothing about it in docs and Google is also not a friend for me today.

  • Sending and receiving IM messages via controller in Rails

    - by Grnbeagle
    Hi, I need a way to handle XMPP communication in my Rails app. My requirements are: Keep an instance of XMPP client running and logged in as one specific user (my bot user) Trigger an event from a controller to send a message and wait for a reply. The message is sent to another machine equipped with a bot so that the reply is supposed to be returned quickly. I installed xmpp4r and backgrounDrb similar to what's described here, but backgrounDrb seems to have evolved and I couldn't get it to wait for a reply. If it has to happen asynchronously, I am willing to use a server-push technology to notify the browser when the reply arrives. To give you a better idea, here are snippets of my code: (In controller) class ServicesController < ApplicationController layout 'simple' def index render :text => "index" end def show @my_service = Service.find(params[:id]) worker = MiddleMan.worker(:jabber_agent_worker) worker.send_request(:arg => {:jid => "someuser@someserver", :cmd => "help"}) render :text => "testing" end end (In worker script) require 'xmpp4r' require 'logger' class JabberAgentWorker < BackgrounDRb::MetaWorker set_worker_name :jabber_agent_worker def create(args = nil) jid = Jabber::JID.new('myagent@myserver') @client = Jabber::Client.new(jid) @client.connect @client.auth('pass') @client.send(Jabber::Presence.new.set_show(:chat).set_status('BackgrounDRb')) @client.add_message_callback do |message| logger.info("**** messaged received: #{message}") # never reaches here end end def send_request(args = nil) to_jid = Jabber::JID.new(args[:jid]) message = Jabber::Message::new(to_jid, args[:cmd]).set_type(:normal).set_id('1') @client.send(message) end end If anyone can tell me any of the following, I'd much appreciate it: issue with my backgrounDrb usage other background process alternatives appropriate for XMPP interactions other ways of achieving this Thanks in advance.

  • How to pass form errors in session or flash? [Rails 2.3.5]

    - by yuval
    I have a create action for a form that potentially generates errors (i.e. first name is missing) and then redirects. The problem is, that when the redirect happens those form errors get lost. How could I pass those form errors in a session to be displayed back in the original form (which should still be filled out with the previous details, as in the original error_messages behavior)? Thanks!

  • Writing a simple incrementing counter in rails

    - by Trip
    For every Card, I would like to attach a special number to them that increments by one. I assume I can do this all in the controller. def create @card = Card.new(params[:card]) @card.SpecNum = @card.SpecNum ++ ... end Or. I can be blatantly retarded. And maybe the best bet is to add an auto-incremement table to mysql. The problem is the number has to start at a specific number, 1020. Any ideas?

  • Passing single attributes to associated factories

    - by lambdabutz
    I'm looking for a way to pass fields into the factories of associated models without having to explicitly call the factory itself. For example, lets say I have some factories like so: Factory.define :person do |person| person.name "Default Bob" person.sex "M" person.house {|p| p.association(:house)} end Factory.define :house do |house| house.color "Red" house.has_ac true house.suburb {|h| h.association(:suburb)} end Factory.define :suburb do |suburb| suburb.name "Little boxes" end This is fine and all, but if I want to use factories to create someone in a specific house in a specific suburb I have do this: sub = Factory(:suburb, :name => "Blue town") house = Factory(:house, :color => "Blue", :suburb => sub) person = Factory(:person, :name => "Bill", :house => house) While this isn't bad in this small case, my actual models sometimes have 7 or 8 associations, and when I want to create an object whose associations I only care about a single attribute, the code for this starts to get really heavy. Is there somewhat I can pass attributes to nested Factories without having to recall the Factory itself?

  • Using Cucumber With Modular Sinatra Apps

    - by Rob Conery
    I'm building out a medium-sized application using Sinatra and all was well when I had a single app.rb file and I followed Aslak's guidance up on Github: http://wiki.github.com/aslakhellesoy/cucumber/sinatra As the app grew a bit larger and the app.rb file started to bulge, I refactored out a lot of of the bits into "middleware" style modules using Sinatra::Base, mapping things using a rack-up file (config.ru) etc. The app works nicely - but my specs blew up as there was no more app.rb file for webrat to run against (as defined in the link above). I've tried to find examples on how to work this - and I think I'm just not used to the internal guts of Cuke just yet as I can't find a single way to have it cover all the apps. I tried just pointing to "config.ru" instead of app.rb - but that doesn't work. What I ended up doing - which is completely hackish - is to have a separate app.rb file in my support directory, which has all the requires stuff so I can at least test the model stuff. I can also specify routes in there - but that's not at all what I want to do. So - the question is: how can I get Cucumber to properly work with the modular app approach?

  • How can I see what capybara found in a failing cucumber step?

    - by ajmurmann
    I started migrating from cucumber + webrat to cucumber + capybara. Now the behavior of "I should see " seems to be somewhat different. Most of these fail now, although I didn't change anything on the page. I replaced the snippet that should be found with some stuff that is on every page and for some text it works and for other text it doesn't. I can't find any pattern in what is found in the page's content and what is not. Webrat used to print what the page content is that it found, in case it did not contain the required phrase. Is there anyway to have capybara show what text it got from the page in which it tried to find the text?

  • Organizing a lot of models that use STI in rails

    - by DavidP6
    I have a scenario where I am going to be creating a large number of models that use STI and I'm wondering what the best way to organize this is. I already have other models using STI and I really do not want to add any more files to my models folder. Is there any way to create a folder and add the models using STI there (there could be upwards of 40 b/c each uses its own methods to scrape a different site, but they all save the same data)? This seems like it would be best, or I could add them all to one file but I would rather separate them.

  • Why rails app is redirecting unexpectedly instead of matching the route?

    - by ruevaughn
    I asked this question earlier and thought it was fixed, but it's not. Previous question here My problem is I am trying to set my routes so that when I type in localhost:3000/sites/admin It should redirect to localhost:3000/en/sites/admin here is my routes.rb file scope ":locale", locale: /#{I18n.available_locales.join("|")}/ do get "log_out" => "sessions#destroy", as: "log_out" get "log_in" => "sessions#new", as: "log_in" resources :sites, except: [:new, :edit, :index, :show, :update, :destroy, :create] do collection do get :home get :about_us get :faq get :discounts get :services get :contact_us get :admin get :posts end end resources :users resources :abouts resources :sessions resources :coupons resources :monthly_posts resources :reviews resources :categories do collection { post :sort } resources :children, :controller => :categories, :only => [:index, :new, :create, :new_subcategory] end resources :products do member do put :move_up put :move_down end end resources :faqs do collection { post :sort } end root :to => 'sites#home' match "/savesort" => 'sites#savesort' end match '', to: redirect("/#{I18n.default_locale}") match '*path', to: redirect("/#{I18n.default_locale}/%{path}") But as of right now, it redirects to /en/en/en/en/en/en/en/en/en/en/sites/admin (adds en until browser complains). Any thoughts why it keeps adding /en?

  • Weird Rails URL issue when rendering a new action

    - by Tony
    I am rendering a new action but somehow getting the "index" URL. To be more specific, my create action looks like this: class ListingsController < ApplicationController def create @listing = Listing.new(params[:listing]) @listing.user = @current_user if @listing.save redirect_to @listing else flash[:error] = "There were errors" render :action => "new" end end end When there are errors, I get the "new" action but my URL is the index URL - http://domain.com/listings Anyone know why this would happen? My routes file is fairly standard: map.connect 'listings/send_message', :controller => 'listings', :action => 'send_message' map.resources :listings map.root :controller => "listings" map.connect ':controller/:action/:id' map.connect ':controller/:action/:id.:format'

  • Mongoid Embeds_many won't save on nested form

    - by Brandon J McKay
    I've got an embeds_many association I'm trying to set up which I've done successfully before, but I'm trying to do it all in one nested form and I can't figure it out. Let's say we have a pocket model: class Pocket include Mongoid::Document field :title, type: String embeds_many :coins, cascade_callbacks: true end and a Coin Model: class Coin include Mongoid::Document field :name, type: String embedded_in :pocket end in my form for the pocket, I'm using: = f.fields_for @pocket.coins do |coin| = coin.text_field :name My controller is the default scaffolded controller. When I use the console, it saves fine and I can see the new pocket and coin I've created. But when I try to create or update a coin from the form, the pocket saves but the coin remains unchanged. What am I missing here?

  • Rails address and routes?

    - by Danny McClelland
    Hi Everyone, I have created a custom action within one of my controlers as follows: # GET /kases/discharge/1 # GET /kases/discharge/1.xml def discharge @kase = Kase.find_by_jobno(params[:id]) respond_to do |format| format.html { } # discharge.html.erb format.xml { render :xml => @kase } format.pdf { render :layout => false } prawnto :prawn => { :background => "#{RAILS_ROOT}/public/images/discharge.png", :left_margin => 0, :right_margin => 0, :top_margin => 0, :bottom_margin => 0, :page_size => 'A4' } end end For the edit actions etc the link would be link_to edit_kase_path(@kase) Is there a way of linking to the discharge action already, or do I have to make a custom route? Thanks, Danny
