  • Path parsing in rails

    - by fl00r
    Hi! I am looking for method for parsing route path like this: ActionController::Routing.new("post_path").parse #=> {:controller => "posts", :action => "index"} It should be opposite to url_for Upd I've found out: http://stackoverflow.com/questions/2222522/what-is-the-opposite-of-url-for-in-rails-a-function-that-takes-a-path-and-genera ActionController::Routing::Routes.recognize_path("/posts") So now I need to convert posts_path into "/posts"

  • rails validation of presence not failing on nil

    - by holden
    I want to make sure an attibute exists, but it seems to still slip thru and I'm not sure how better to check for it. This should work, but doesn't. It's a attr_accessor and not a real attribute if that makes a difference. validates_presence_of :confirmed, :rooms {"commit"=>"Make Booking", "place_id"=>"the-kosmonaut", "authenticity_token"=>"Tkd9bfGqYFfYUv0n/Kqp6psXHjLU7CmX+D4UnCWMiMk=", "utf8"=>"✓", "booking"=>{"place_id"=>"6933", "bookdate"=>"2010-11-22", "rooms"=>[{}], "no_days"=>"2"}} Not sure why my form_for returns a blank hash in an array... <% form_for :booking, :url => place_bookings_path(@place) do |f| %> <%= f.hidden_field :bookdate, { :value => user_cart.getDate } %> <%= f.hidden_field :no_days, { :value => user_cart.getDays } %> <% for room in pricing_table(@place.rooms,@valid_dates) %> <%= select_tag("booking[rooms][][#{room.id}]", available_beds(room)) %> <% end %> <% end %>

  • How does Rails find models and controllers? How can I get it to load more models?

    - by David
    I'm trying to create a non-ActiveRecord model in app/models/gamestate.rb. Then inside my controller (PlayController) I should be able to do GameState.new, right? No go: NameError (uninitialized constant PlayController::GameState): app/controllers/play_controller.rb:23:in `play' (at least in the development environment) But! If I do have a model called app/models/play.rb, then it's automatically loaded and I can do Play.new. So my question is: how does Rails know which classes to load? What sort of name mangling does it do to get from play#action to PlayController to app/controllers/play_controller.rb to app/models/play.rb? It seems awfully fragile, but maybe a better understanding of how this works would help. And finally, how can I get it to load app/models/gamestate.rb?

  • Full text search for irregular rapper names with Solr

    - by Horace Loeb
    I'm implementing full text search functionality on my rap website, and I'm running into some issues with rapper and song names. For example, someone might want to search for the rapper "Cam'ron" using the query "camron" (leaving out the mid-word apostrophe). Likewise, someone might search for the song "3 Peat" using the query "3peat". "The Notorious B.I.G." is a bit of a weird case: both "The Notorious BIG" and "The Notorious B.I.G." both work (I guess because the solr.StandardFilterFactory removes dots from acronyms?), but "The Notorious B.I.G" (i.e., minus the trailing dot) doesn't. Ideally all reasonable variations of these names should work. I'm guessing the answer has something to do with the solr.WordDelimiterFilterFactory, but I'm not sure. Also, I'm using Sunspot with Rails if that's relevant.

  • Upgraded activerecord-sqlserver-adapter from 2.2.22 to 2.3.8 and now getting an ODBC error

    - by stuartc
    I have been using MSSQL 2005 with Rails for quite a while now, and decided to bump my gems up on one of my projects and ran into a problem. I moved from 2.2.22 to 2.3.8 (latest as of writing) and all of a sudden I got this: ODBC::Error: S1090 (0) [unixODBC][Driver Manager]Invalid string or buffer length I'm using a DSN connection with FreeTDS my database.yml looks like this: adapter: sqlserver mode: ODBC dsn: 'DRIVER=FreeTDS;TDSVER=7.0;SERVER=10.0.0.5;DATABASE=db;Port=1433;UID=user;PWD=pwd;' Now in the mean time I moved back to 2.2.22 and there are no deprecation warnings and everything seems fine but obviously for the sake of being up to date, any ideas what could have changed in the adaptor that could cause this?

  • What's the fastest way to check if a word from one string is in another string?

    - by Mike Trpcic
    I have a string of words; let's call them bad: bad = "foo bar baz" I can keep this string as a whitespace separated string, or as a list: bad = bad.split(" "); If I have another string, like so: str = "This is my first foo string" What's the fasted way to check if any word from the bad string is within my comparison string, and what's the fastest way to remove said word if it's found? #Find if a word is there bad.split(" ").each do |word| found = str.include?(word) end #Remove the word bad.split(" ").each do |word| str.gsub!(/#{word}/, "") end

  • Rails helper module undefined method `sort'

    - by Magicked
    I'm trying to create a simple helper module in rails, and I'm stumped on the following error message from my new person form (app/views/people/new.html.erb): undefined method `sort' for 97:Fixnum Extracted source (around line #17): 14: <p> 15: <% nations = { 'United States of America' => 'USA', 'Canada' => 'Canada', 'Mexico' => 'Mexico', 'United Kingdom' => 'UK' } %> 16: <%= f.label :country %><br /> 17: <%= radio_buttons(:person, :country, nations) %> 18: 19: </p> 20: <p> radio_buttons is a helper module I have created for my view. Here it is (app/helpers/people_helper.rb): module PeopleHelper def radio_buttons(model_name, target_property, button_source) html='' list = button_source.sort list.each do |x| html << radio_buttons(model_name, target_property, x[1]) html << h(x[0]) html << '<br />' end return html end end The problem appears to be on the "list = button_source.sort", but I'm not sure why it says the method is undefined. I have been able to use it directly within my view code. Am I not able to use methods like this within helper modules? Do I need to include something? Thanks for any help!

  • RoR - Polyline in GoogleMaps

    - by Arwed
    I'm using Ym4r and want to add a polyline to my map.

  • Access params[] and local attributes in static class as *_filter

    - by Mattias
    Hi! I'm trying to refactor some code and move some of my before_filter's from the controller to a class. Before: class UsersController < ApplicationController before_filter :find_user def find_user @user = User.find(params[:id]) end end ... After class FindUserFilter def self.filter(controller) @user = User.find(params[:id]) end end class UsersController < ApplicationController before_filter FindUserFilter end class GuestbookController < ApplicationController before_filter FindUserFilter end This results in an error because neither params[:id] nor @user is available/definable in the FindUserFilter-class. Any idea how to fix this?

  • Internationalization of static pages with Rails

    - by Gavin
    I feel like I'm missing something really simple and I keep spinning my wheels on this problem. I currently have internationalization working throughout my app. The translations work and the routes work perfectly. At least, most of the site works with the exception of the routes to my two static pages, my "About" and "FAQ" pages. Every other link throughout the app points to the proper localized route. For example if I select "french" as my language, links point to the appropriate "(/:locale)/controller(.:format)." However, despite the changes I make throughout the app my links for the "About" and "FAQ" refuse to point to "../fr/static/about" and always point to "/static/about." To make matters stranger, when I run rake routes I see: "GET (/:locale)/static/:permalink(.:format) pages#show {:locale=/en|fr/}" and when I manually type in "../fr/static/about" the page translates perfectly. My Routes file: devise_for :users scope "(:locale)", :locale => /en|fr/ do get 'static/:permalink', :controller => 'pages', :action => 'show' resources :places, only: [:index, :show, :destroy] resources :homes, only: [:index, :show] match '/:locale' => 'places#index' get '/'=>'places#index',:as=>"root" end My ApplicationController: before_filter :set_locale def set_locale I18n.locale=params[:locale]||I18n.default_locale end def default_url_options(options={}) logger.debug "default_url_options is passed options: #{options.inspect}\n" { :locale => I18n.locale } end and My Pages Controller: class PagesController < ApplicationController before_filter :validate_page PAGES = ['about_us', 'faq'] def show render params[:permalink] end def validate_page redirect_to :status => 404 unless PAGES.include?(params[:permalink]) end end I'd be very grateful for any help ... it's just been one of those days. Edit: Thanks to Terry for jogging me to include views. <div class="container-fluid nav-collapse"> <ul class="nav"> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown"><%= t(:'navbar.about') %><b class="caret"></b></a> <ul class="dropdown-menu"> <li><%=link_to t(:'navbar.about_us'), "/static/about_us"%></li> <li><%=link_to t(:'navbar.faq'), "/static/faq"%></li> <li><%=link_to t(:'navbar.blog'), '#' %></li> </ul> </li>

  • Should I define models that will be owned by many different models or use controller and views?

    - by jgervin
    I am struggling to figure out how to get a relationship between several models. I have sales_leads which I need to view by company and by event. So if someone looks up the leads by company they can see all leads across all events, but also see all leads by event. Not sure if this is ownership versus a where? Should it be something like Company.sales_leads where("event.event_id = ?", "2356") Or Models: sales_lead belongs_to event belongs_to company

  • Parsing a CSV File to a Rails Database

    - by Schroedinger
    G'day guys, I'm using fasterCSV and a rake script to parse a csv with about 30 columns into my rails db for a 'Trade' item. The script works fine when all of the values are set to strings, but when I change it to a decimal, int or other value, everything goes to hell. Wondering if fasterCSV has built in int etc parsing or whether I'll have to manage these within my model. Basically, I'm given a giant amount of trades data, need to import it, and then need to provide feedback with say the average trade volume, the times, etc. I understand I can do that all with the wonderful records provided to me by activeRecord but wondered if there was an easier way to populate a rather large Database with a given CSV? Several of the fields don't have values for certain rows, fasterCSV seems to work perfectly when they're all strings, but not when I try to get decimal or other.

  • Remove unncessary error raised by paperclip - filename is not recognized by the 'identify' command.

    - by kgpdeveloper
    I've been searching on how to solve this issue but could not find any real and working solution. User model: validates_attachment_content_type :avatar, :content_type = ['image/jpeg', 'image/pjpeg', 'image/x-png', 'image/png', 'image/gif'] Unnecessary error shows up when invalid file type is uploaded: Avatar /tmp/sample,23283,0.txt is not recognized by the 'identify' command. Server details: Ubuntu and Debian which identify results to /usr/bin/identify Specifying command path does not solve the issue: Paperclip.options[:command_path] = "/usr/bin" Any ideas? I looked at geometry.rb file and there seems to be something wrong with it. def self.from_file file file = file.path if file.respond_to? "path" geometry = begin Paperclip.run("identify", %Q[-format "%wx%h" "#{file}"[0]]) rescue PaperclipCommandLineError "" end parse(geometry) || raise(NotIdentifiedByImageMagickError.new("#{file} is not recognized by the 'identify' command.")) end Let me know if anyone has solved the same issue and how. Many thanks.

  • What's with bad function call in view generated via scaffold?

    - by meta
    I've scaffolded Things element: script/generate scaffold wip/thing name:string and got some invalid function call in views, like: <td><%= link_to 'Edit', edit_thing_path(thing) %></td> Which raise this error: ActionView::TemplateError (undefined method `edit_thing_path' for #<ActionView::Base:0xb5c00944>) on line #11 of app/views/wip/things/index.html.erb: 8: <tr> 9: <td><%=h thing.name %></td> 10: <td><%= link_to 'Show', thing %></td> 11: <td><%= link_to 'Edit', edit_thing_path(thing) %></td> 12: <td><%= link_to 'Destroy', thing, :confirm => 'Are you sure?', :method => :delete %></td> 13: </tr> 14: <% end %> What's with that function? Where is it? Is it some kind of automagic stuff or do I need to implement it (if so - where should it go?) I have resource defined in routes with namespace: map.namespace :wip do |wip| wip.resources :things end rake routes gives me this: wip_things GET /wip/things(.:format) {:action=>"index", :controller=>"wip/things"} POST /wip/things(.:format) {:action=>"create", :controller=>"wip/things"} new_wip_thing GET /wip/things/new(.:format) {:action=>"new", :controller=>"wip/things"} edit_wip_thing GET /wip/things/:id/edit(.:format) {:action=>"edit", :controller=>"wip/things"} wip_thing GET /wip/things/:id(.:format) I assumed that those names (wip_thing, new_wip_thing) are the correct names, but it's still gives me that error Thanks.

  • adding custom fields dynamically to a model

    - by pankajbhageria
    I have a model called List which has many records: class List has_many :records end class Record end The table Record has 2 permanent fields: name, email. Besides these 2 fields, for each List a Record can have 'n' custom fields. For example: for list1 I add address(text), dob(date) as custom fields. Then while adding records to list one, each record can have values for address and dob. Is there any ActiveRecord plugin which provides this type of functionality? Or else could you share your thoughts on how to model this? Thanks in advance, Pankaj

  • Multiple inputs on a single line with Twitter Bootstrap and Simple Form 2.0

    - by noel_g
    I am using simple_form 2.0 with twitter bootstrap. I am trying to determine what is the proper wrapper format in order to get something like [city] [State] [Zip] I believe my form needs to be <div class="control-group"> <%= f.input :city,:wrapper => :small, :placeholder => "City", :input_html => { :class=>"span2", :maxlength => 10},:label => false %> <%= f.input :region, :wrapper => :small , :placeholder => "Region", :input_html => { :class=>"span1", :maxlength => 5}, :label => false %> <%= f.input :postal_code, :wrapper => :small, :placeholder => "Postal Code",:input_html => { :class=>"span2", :maxlength => 10},:label => false %> </div> I tried this wrapper config.wrappers :small, :tag => 'div', :class => 'controls inline-inputs', :error_class => 'error' do |b| b.use :placeholder b.use :label_input end I believe I would need to define the CSS as well, but before I go down a rabbit hole I thought I would ask if this is built in somewhere.
