• Is it possible to use best_in_place with typeahead from twitter bootstrap?

  - by Dave H

  Basically, I am using best_in_place in my rails webapp to let users edit their profile info in place. The thing is, I would like users to be presented with a typeahead form for certain entries.. Here's what I'm working with: <p>College/University: <input type="text" class="span3" style="margin: 0 auto;" data-provide="typeahead" data-items="8" data-source='["University of Pennsylvania","Harvard","Yale","Princeton","Cornell","Brown","Columbia","Dartmouth"]'></p> This gives me a working form box with typeahead. However, I want to be able to wrap this in best_in_place with something like <%= best_in_place @student, :education %> so that users only see the typeahead form when they click on the text, and upon clicking away from the box or hitting enter the selection is stored in the database. Is there a reasonably easy way to do this?

• MCSD Certification, any recommended study material?

  - by Dayan

  I wish to study for the new MCSD Certification For web applications: I headed over to Amazon in search of some books and had no luck with finding anything up to date, most books are outdated, such as the list provided by Amazon MCSD Books. Is this because the test is more based on experience rather than just an understanding of the subject? Any tips and/or recommended materials will be appreciated, thank you!

  I have several students that want a course of Ubuntu.

• Rails - how to use a plugin from github (how to install, utilize, etc)

  - by jyoseph

  I'm trying to install a couple of different plugins for my rails 3 app. I cd to '/vendor/plugins/', then type git clone the_git_src_url. I see the files in the /vendor/plugins/ directory. However when I try to use any of the tags provided by the plugin I get uninitialized constant ContentsController::HTMLToTextileParser PriceTag and html2textile are the two plugins I'm trying to use. This is what triggers the error above: <%= PriceTag.html_to_textile(@content.desc) %> I'm working in development, I've tried to restart the server. Is there something I'm missing?

• Rails Counter Cache and its implementation

  - by Ishu

  Hello All, I am trying to get hold of rails counter cache feature but not able to grasp it completely. Let's say that We have 3 models A B C A belongs to B or C depending upon a field key_type and key_id. key_type tells whether A belongs to B or C so if key_type="B" then the record belongs to B otherwise it belongs to C. In my model a.rb, I have defined following associations: belongs_to :b, :counter_cache => true, :foreign_key => "key_id" belongs_to :c, :counter_cache => true, :foreign_key => "key_id" and in b and c model files has_many :as , :conditions => {:key_type => "B"} has_many :as , :conditions => {:key_type => "C"} Both B and C Models have a column as as_count The problem is every time an object of a is created count is increased in the both the models b and c. Any help is appreciated. Initially i thought that this may work: belongs_to :b, :counter_cache => true, :foreign_key => "key_id", :conditions => {:key_type => "B"} belongs_to :c, :counter_cache => true, :foreign_key => "key_id", :conditions => {:key_type => "C"} But this does not help. Thanks

• Rails add a param to the end of a search query

  - by bob

  Hello, I am trying to implement a sort on the returned results of a search with rails. Filter by: 'recent' % | 'lowest_price' % | 'highest_price' % here are my links. I would like to add a filter to the end of my search query. So for example, I submit a search and I get back results and in my url I have http://localhost:3000/junks?search=handbag&condition=&category=&main_submit=Go! I would then like the user to be able to click one of the above links and have the page come back with a new query (i have this set up in the controller like such) con_id = params[:condition] if params[:category].nil? || params[:category].empty? cat_id = params[:category] results = Junk.search params[:search], :with => { :category_id => cat_id, :condition_id => con_id } case params[:filter] when "lowest_price" @junks = results.lowest_price.paginate :page => params[:page], :per_page => 12 when "highest_price" @junks = results.highest_price.paginate :page => params[:page], :per_page => 12 else @junks = results.paginate :page => params[:page], :per_page => 12 end else I would like the user to be able to click on of the above links and append a filter param to the end of the search query so that my controller can pick it up and call the correct database queries as seen in the case statement above. I'm guessing the url will look like this http://localhost:3000/junks?search=handbag&condition=&category=&main_submit=Go!&filter="lowest_price" How can I do this? Is there a better way?

• Run Rails 3 app on a Rails 2 server/machine?

  - by chucknelson

  I'm trying to run a Rail 3 (3.0.10) app on a shared joyent smartmachine server (I don't have root access) which has Rails 2 (2.3.11) installed , and I'm not sure what to do after I freeze my Rails 3 app with bundle install --deployment. It seems like with the Rails 3 and bundler gems not being installed on the server locally, my app isn't even recognizing the local version of Rails I have frozen with my app. Has anyone gotten this to work, or have any advice? The server runs Apache, and I think I can get lighttpd installed too - but I'd rather stay with Apache if I can. Also, if it matters, Passenger is not an installed gem either...and I'm not sure I can freeze that with my app. Update 11/30/2011 12:30 PM EST Bundler is not installed on this server, either. Not sure if having that would enable the new Rails 3 "freeze" (bundle --deployment) to work or not...

• How to extend an 'unloadable' Rails plugin?

  - by Vitaly Kushner

  I'm trying to write a plugin that will extend InheritedResources. Specifically I want to rewrite some default helpers. And I'd like it to "just work" once installed, w/o any changes to application code. The functionality is provided in a module which needs to be included in a right place. The question is where? :) The first attempt was to do it in my plugin's init.rb: InheritedResources::Base.send :include, MyModule It works in production, but fails miserably in development since InheritedResource::Base declared as unloadable and so its code is reloaded on each request. So my module is there for the first request, and then its gone. InheritedResource::Base is 'pulled' in again by any controller that uses it: Class SomeController < InheritedResource::Base But no code is 'pulling in' my extension module since it is not referenced anywhere except init.rb which is not re-loaded on each request So right now I'm just including the module manually in every controller that needs it which sucks. I can't even include it once in ApplicationController because InheritedResources inherites from it and so it will override any changes back.

• Error handling in Rails Controller for adding embedded Mongoid documents to Model

  - by Dragonfly

  I have a Item model that has embedded documents. Currently, the following comments_controller code will add a comment to the item successfully. However, if pushing the comment document onto the comments array on item fails, I will not know this. #this does work, but i do not know if the push fails def create comment = Comment.new(:text => params[:text]) @item.comments << comment render :text => comment end I would like to have something like this, but @item.comments << comment does not return true or false: #this does not work def create comment = Comment.new(:text => params[:text]) if @item.comments << comment render :text => comment else render :text => 'oh no' end end Nor does it throw an exception when the document push fails: #this does not work def create begin comment = Comment.new(:text => params[:text]) @item.comments << comment render :text => comment rescue Exception => e render :text => 'oh no' end end Thanks!

• Can't store array in json field in postgresql (rails) can't cast Array to json

  - by Drew H

  This is the error I'm getting when I run db:migrate rake aborted! can't cast Array to json This is my table class CreateTrips < ActiveRecord::Migration def change create_table :trips do |t| t.json :flights t.timestamps end end end This is in my seeds.rb file flights = [{ depart_time_hour: 600, arrive_time_hour: 700, passengers: [ { user_id: 1, request: true } ] }] trip = Trip.create( { name: 'Flight', flights: flights.to_json } ) For some reason I can't do this. If I do this. trip = Trip.create( { name: 'Flight', flights: { flights: flights.to_json } } ) It works. I don't want this though because now I have to access the json array with trip.flights.flights. Not the behavior I'm wanting.

• Rails 3.0/3.2: Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id

  - by Nick5a1

  I'm following the Kevin Skoglund tutorial Ruby on Rails 3 Essential Training, which was written for rails 3.0, though I am currently using 3.2. It uses the following method in the pages_controller with a before_filter to display only the pages which belong to the parent subject. The tutorial explicitly uses .find_by_id because if the result is nil it "will not return an error". However I get the "Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id" error when trying to view a page where @subject has been set to nil. def find_subject if params[:subject_id] @subject = Subject.find_by_id(params[:subject_id]) end end The actual code that is causing the error is: def list @pages = Page.order("pages.position ASC").where(:subject_id => @subject.id) end Is this something that has changed since 3.0? If so, what would be the correct way to implement this functionality in 3.2?

I have Ruby: 1.8.7 I have just upgraded Rails to: 3.0.3 All I am trying to accomplish is to be able to render localhost.com:3000 in my browser of the GIT project i've already downloaded so I can work on it locally.
