  • Apache + Passenger not passing on custom status codes

    - by harm
    I'm currently building an API. This API communicates with the client via status codes. I created several custom status codes (as per http://www.w3.org/Protocols/rfc2616/rfc2616-sec6.html#sec6) in order to inform the client on certain things. For example I introduced the 481 status code to signify a specific client error. The Rails app I wrote works like a charm. But when Apache and Passenger are serving it things run aground. When I provoke a 481 error the response header looks like this: HTTP/1.1 500 Internal Server Error Date: Wed, 19 May 2010 06:37:05 GMT Server: Apache/2.2.9 (Debian) Phusion_Passenger/2.2.5 mod_ssl/2.2.9 OpenSSL/0.9.8g X-Powered-By: Phusion Passenger (mod_rails/mod_rack) 2.2.5 Cache-Control: no-cache X-Runtime: 1938 Set-Cookie: _session_id=32bc259dc763193ad57ae7dc19d5f57e; path=/; HttpOnly Content-Length: 62 Status: 481 Content-Type: application/json; charset=utf-8 As you can see the original Status header is still there almost a the end. But the 'true' status header (the very first line) is quiet different. It seems that Apache doesn't like Status headers it has no knowledge of and thus assumes an error. Is there anyway to fix this? Maybe via the mod_headers ( http://httpd.apache.org/docs/2.2/mod/mod_headers.html) module? I don't know enough of Apache to figure this out on my own. Thanks,

  • Form to sort an index in rails

    - by shmichael
    I'm a newcomer to Rails. I want to build a simple form that determines the sort order of a list. I've implemented a form in the likes of - <%= radio_button_tag :sort, "rating" %> <%= label_tag :sort_rating, "order by rating" %> <%= radio_button_tag :sort, "name" %> <%= label_tag :sort_name, "order by name" %> And now I am unsure how to implement the sort at the controller/model level. The aspects I am puzzled about are: Where should the sort be performed How could the sort parameter be persisted How could the code be reused Right now, I can't even get the selected sort method to remain selected after a submit. I would most appreciate any guidance or reference to an example.

  • rendering specific fields with Rails

    - by Tam
    Hi, If I have an object say @user and I want to render only certain fields in it say first_name and last_name(I'm using AMF) render :amf => @user how do I do that? I know I can use :select when doing the 'find' but I need to use the other field at the server side but don't want to send them with AMF to the client side and I don't want to do a second 'find' Thanks, Tam

  • Rails form helper and RESTful routes

    - by Jimmy
    Hey guys, I have a form partial current setup like this to make new blog posts <% form_for([@current_user, @post]) do |f| %> This works great when editing a post, but when creating a new post I get the following error: undefined method `user_posts_path' for #<ActionView::Base:0x6158104> My routes are setup as follows: map.resources :user do |user| user.resources :post end Is there a better way to setup my partial to handle both new posts and editing current posts?

  • Why are my ActiveRecord class instance variables disappearing after the first request in development

    - by Paul C
    I have a class instance variable on one of my AR classes. I set its value at boot with an initializer and, after that, never touch it again except to read from it. In development mode, this value disappears after the first request to the web server. However, when running tests, using the console or running the production server this does not happen. # The AR class class Group < ActiveRecord::Base class << self attr_accessor :path end end # The initializer Group.path = File.join(RAILS_ROOT, "public", "etc") # First request in a view %p= Group.path #=> "/home/rails/app/public/etc" # Second request in a view %p= Group.path #=> nil Is there something about development mode that nukes instance variables from classes with each request? If so, is there a way to disable this for specific variables or classes?

  • Can 'locals' be used with 'collection' when rendering partials in Rails?

    - by Gav
    Everything works okay when I try to render a partial like this: = render :partial => "/shared/enquiry/car_type", :collection => @enquiry.available_car_types However, if I also want to pass a variable (in this case 'path', because I'm sharing this partial across two forms), the path is not available to me: = render :partial => "/shared/enquiry/car_type", :collection => @enquiry.available_car_types, :locals => {:path => customers_enquiry_path} I've tried moving things around, but nothing appears to work, leading me to believe one cannot use locals with collections. Any help would be appreciated. Gav

  • Sql query Error: Operand should contain 1 column(s) in rails

    - by dombesz
    Hi everyone, SELECT * FROM jobs WHERE (SELECT DISTINCT jobs.* FROM jobs, job_requests WHERE (jobs.user_id = 1) OR (job_requests.user_id = 1 AND job_requests.job_id = jobs.id)) This sql gives me Mysql::Error: Operand should contain 1 column(s). If i execute the select from the where clause it works SELECT DISTINCT jobs.* FROM jobs, job_requests WHERE (jobs.user_id = 1) OR (job_requests.user_id = 1 AND job_requests.job_id = jobs.id) Could somebody explain me why? This query is generated by rails activerecord so the main select is needed.

  • many to many query for ActiveRecord

    - by JP
    I have three data models, Users, Conversations and Lines, where each conversation has many lines and certain participating users, each line has one conversation and one user and each user has many conversations and many lines. I have arranged these in ActiveRecord like this: class Line < ActiveRecord::Base belongs_to :conversation belongs_to :user end class User < ActiveRecord::Base has_and_belongs_to_many :conversations has_many :lines end class Conversation < ActiveRecord::Base has_many :lines has_and_belongs_to_many :users end If I want to create a new conversation with 4 users, where the users are either found or created inside the users table, how would I go about doing this? I thought I could do: c = Conversation.new c.users.find_or_create_by_username('myUsername') c.save But this will create a new username in the Users table even if that username already exists! (ie. running the above code 3 times will result in Users having 3 rows with 'myUsername' as the username, one for each conversation, rather than three conversations all with the same 'myUsername' entry listed in their associated users) I'm not sure how to search for this kind of information with google - can anyone help?

  • Imagemagick Resizing in Paperclip

    - by jonathan.soeder
    So, I want to resize images to a FIXED width, but proportional height. I have been trying a wide range of operators: 380x242# 380x242 380!x242 380x242< none of them have the desired effect. Any help? I want it to fill or resize to the 380 width, then resize / shrink the height by the same factor it used to shrink or resize the image to 380 wide.

  • How do I best run a search on Date when it is not a :has_many association?

    - by Angela
    I have a number of activities that have a calculated scheduled date. The activities, for example, Email, have a email.days method which is the days from a Contact.start_date on which it should be sent. This means contact.start_date + email.days yields a date on which email is sent to contact. I would like to use link_to around the date, so I can see all the emails and associated contacts that are to be scheduled on that date. However, this "date" is not an attribute or an associate, so I'm not linking to a model's view. It's calculated. So: 1) What should the actual "format" of the date that gets passed in the URl be? What is the method to do the consistent conversion? 2) How do I (find) all instances, because this "date" is not an actual attribute, is it a calculated value which changes depending on the two associated models of Contact and Email. Thanks.

  • Multiple forms using Rails & jQuery & AJAX

    - by biggie8199
    I have multiple coupons on a page and I'm trying to get comments to work on each coupon. So for each coupon i have a comments form. Im using jQuery + Ajax to accomplish this. Here's what my code looks like. Coupon Page <p>Comments:</p> <% form_for(@comment) do |f| %> <%= f.label :body %><br /><%= f.text_field :body, :size => "24" %> <%= f.hidden_field :coupon_id, :value => coupon.id %> <%= f.submit "Save" %> <% end %> Application.js jQuery.ajaxSetup({ 'beforeSend': function(xhr) {xhr.setRequestHeader("Accept", "text/javascript")} }) jQuery.fn.submitWithAjax = function() { this.submit(function() { $.post(this.action, $(this).serialize(), null, "script"); return false; }) return this; }; $(document).ready(function() { $("#new_comment").submitWithAjax(); }) I tried changing the jQuery selector to a class $(".new_comment").submitWithAjax(); Thinking that would work, now all the submit buttons work, however it posts only the first form on the page. What can I change to make it so ajax submits the correct form and not the first one?

  • Unit Testing a rails 2.3.5 plugin

    - by brad
    I'm writing a new plugin for a rails 2.3.5 app. I've included an app directory (which makes it an engine) so i can easily load some extra routes. Not sure if that affects anything. Anyway, in the test directory i have two files: test_helper.rb and my_plugin_test.rb These files were generated automatically using script/generate plugin my_plugin When I go to vendor/plugins/my_plugin directory and run rake test they don't seem to run. I get the following console output: (in /Users/me/Repos/my_app/source/trunk/vendor/plugins/my_plugin) /Users/me/.rvm/rubies/jruby-1.4.0/bin/jruby -I"lib:lib:test" "/Users/me/.rvm/gems/jruby-1.4.0/gems/rake-0.8.7/lib/rake/rake_test_loader.rb" "test/my_plugin_test.rb" So it obviously sees my test file, but none of the tests inside get run, I just get back to my console prompt. What am I missing here? I figured the generated code would work out of the box Here are the two files test_helper.rb require 'rubygems' require 'active_support' require 'active_support/test_case' my_plugin_test.rb require 'test_helper' class MyPluginTest < ActiveSupport::TestCase # Replace this with your real tests. test "the truth" do assert true end test "Factories are supported" do assert_not_nil Factory end end File structure vendor - plugins - my_plugin - app - config - routes.rb - generators - my_plugin - some generator files.rb - lib - my_plugin.rb - my_plugin - my_plugin_lib_file.rb - rails - init.rb - Rakefile - tasks - my_plugin_tasks.rake - test - test_helper.rb - my_plugin_test.rb

  • Rails messing up with HTTP POST Params

    - by Julien Genestoux
    Our app provides an API that people can use to submit URLs like this: curl -X POST http://app.local/resource -d'url=http://news.google.com/newshl=en&q=obama&um=1&ie=UTF-8&output=rss' Unfortunately, it seems that Rails messes up with this param. Any idea on how to fix this? See the log below : Processing ApplicationController#index (for 127.0.0.1 at 2010-06-08 19:03:09) [POST] Parameters: {"um"=>"1", "url"=>"http://news.google.com/newshl=en", "output"=>"rss", "q"=>"obama", "ie"=>"UTF-8"} I would expect the following : Parameters: {"url"=>"hhttp://news.google.com/newshl=en&q=obama&um=1&ie=UTF-8&output=rss"}

  • Splitting PDF to png

    - by Josh Crowder
    I'm using paperclip to upload a pdf. Once the file is uploaded I need to split every page into a png. This is the command I think I need to use convert -size 640x300 fileName.pdf slide.png Now if I run that command from terminal it works fine, but I need a way of getting each slides name so I can add it into a model. What's the best way to achieve this?

  • Test if current page is inside a shadowbox? (so i can close the shadowbox and reopen that page in t

    - by Max Williams
    Hi all I have a couple of pages in my site which open in a shadowbox window rather than the main window. My problem is that if the user session expires, then the user clicks on one of the links that open in a shadowbox, they are redirected to the login page INSIDE THE SHADOWBOX, which i don't want. I've been trying to think of the best way to handle this - one way i thought of, which seems a bit clumsy tbh, was on the login page to test if we're in a shadowbox, and if we are then close it and redirect the parent window to the login page. a) does this seem like a sensible plan? I added the following to my login page, which works: $(document).ready(function(){ if(window.parent.location != window.location){ window.parent.location.href = window.location; } } but i have to wait for the shadowbox to finish loading the page and then redirect. So it's working but like i say a bit clumsy. Is there a nicer way? grateful for any advice - max

When I check the params array using the debugger the data is not sent. Does anyone have any idea or sugestions? Thanks

  • Help porting a bit of Prototype JavaScript to jQuery

    - by ewall
    I have already implemented some AJAX pagination in my Rails app by using the example code for the will_paginate plugin--which is apparently using Prototype. But if I wanted to switch to using jQuery for future additions, I really don't want to have the Prototype stuff sitting around too (yes, I know it's possible). I haven't written a lick of JavaScript in years, let alone looked into Prototype and jQuery... so I could use some help converting this bit into jQuery-compatible syntax: document.observe("dom:loaded", function() { // the element in which we will observe all clicks and capture // ones originating from pagination links var container = $(document.body) if (container) { var img = new Image img.src = '/images/spinner.gif' function createSpinner() { return new Element('img', { src: img.src, 'class': 'spinner' }) } container.observe('click', function(e) { var el = e.element() if (el.match('.pagination a')) { el.up('.pagination').insert(createSpinner()) new Ajax.Request(el.href, { method: 'get' }) e.stop() } }) } }) Thanks in advance!

  • Create calendardateselect from javascript

    - by 99miles
    Not sure why I can't figure this out. When a user makes a selection, a javascript method is called, at which point I want to add a calendardateselect to an existing div tag from the javascript. According to the docs, it seems like this should work: var a = new CalendarDateSelect( document.getElementById("date_area"), {embedded:true, year_range:10} ); $('date_area').insert(a); ... or maybe this.... var newScript = document.createElement('script'); newScript.type = 'text/javascript'; var tn = document.createTextNode("new CalendarDateSelect( $(this).previous() )"); newScript.appendChild(tn); $('date_area').insert(newScript); http://code.google.com/p/calendardateselect/wiki/JavascriptDocumentation But neither of them are working. I feel like I've tried everything. Ideas?
