  • Why is this line breaking Rails with Passenger on DreamHost?

    - by Frew
    Ok, so I have a Rails app set up on DreamHost and I had it working a while ago and now it's broken. I don't know a lot about deployment environments or anything like that so please forgive my ignorance. Anyway, it looks like the app is crashing at this line in config/environment.rb: require File.join(File.dirname(__FILE__), 'boot') config/boot.rb is pretty much normal, but I'll include it here anyway. # Don't change this file! # Configure your app in config/environment.rb and config/environments/*.rb RAILS_ROOT = "#{File.dirname(__FILE__)}/.." unless defined?(RAILS_ROOT) module Rails class << self def boot! unless booted? preinitialize pick_boot.run end end def booted? defined?

  • Can using Chronic impair you sense of time?

    - by Trip
    Haha.. I'm using Chronic to parse the time users add in the Calendar. Where the code works and implements the right time, the end result is that, IF a user adds a time, then it has no date, and because it has no date, it will not show in results. Any ideas? def set_dates unless self.natural_date.blank? || Chronic.parse(self.natural_date).blank? # check if we are dealing with a date or a date + time if time_provided?(self.natural_date) self.date = nil self.time = Chronic.parse(self.natural_date) else self.date = Chronic.parse(self.natural_date).to_date self.time = nil end end unless self.natural_end_date.blank? || Chronic.parse(self.natural_end_date).blank? # check if we are dealing with a date or a date + time if time_provided?(self.natural_end_date) self.end_date = nil self.end_time = Chronic.parse(self.natural_end_date) else self.end_date = Chronic.parse(self.natural_end_date).to_date self.end_time = nil end end end

  • why is link generated in YUI javascript failing to render in rails?

    - by pmneve
    Using YAHOO.widget.treeview to generate a table with three levels of data: module, submodule, and detail. If there is an image associated with a detail row the javascript generates a link: "<td><a href=\"/screenshot/show/" + rowData.id + "\">Screenshot</a></td>" that is appended to the html for the row. The url is generated correctly and the link appears. When clicked nothing happens except the word 'Done' appears in the browser status bar. Am calling the very same url from another page that does not use javascript and the screenshot page appears as expected. Here is the controller. class ScreenshotController < ApplicationController def show if @detail.screen_path.length 1 @imagePath = "#{RAILS_ROOT}" + "/private/#{Company.find(@detail.company_id).subdir}/" + "#{Project.find(@detail.project_id).subdir}/screenshot/" + "#{@detail.screen_path}" send_file ( @imagePath, :type = 'image/jpeg', :disposition = 'inline') end end end A sample url: http://localhost:3004/screenshot/show/20854 This code from show.html.erb belonging to the detail model works: <%= link_to 'View', :controller = 'screenshot', :id = @detail.id, :action = 'show' % Any ideas???

  • Problem with url_for in ActionMailer template

    - by macek
    I'm attempting to provide a confirmation link in my user welcome email and I'm getting the following Rails error: Need controller and action! It makes a fuss about this line: <p>Please take a moment to activate your account by going to: <%= link_to confirm_user_url(:id => @user.confirmation_code) %>.</p> In my development.rb environment, I have the following line: config.action_mailer.default_url_options = { :host => "localhost", :port => 3000 } There's no problem with the @user variable. I've tested the email with things like @user.username and @user.confirmation_code. I'm only getting trouble with url_for and named routes like confirm_user_url. When I check my routes with rake routes, confirm_user shows up, so it's not an issue with the named route not existing. I can't seem to figure it out. What gives?

  • Simple Sinatra Ajax Not Working

    - by proteantech
    I was trying make an AJAX call from a static file on my computer to a simple sinatra service. The ajax call was returning with an error and no details. The server logged no errors either. Another strange symptom was that the Origin in the request header was null. I turns out that you can't make cross domain ajax calls without a little extra effort. You can set the Access-Control-Allow-Origin header on your sinatra response to expose your service to external domains using a snippet like this: get '/hi' do response['Access-Control-Allow-Origin'] = '*' content_type 'text/plain' "Hello World" end There's also another header you can set to allow other HTTP Methods besides gets, Access-Control-Request-Method. You can find more information by searching around for CORS: Cross Origin Resource Sharing and the previously mentioned headers. Oh, and in case you want to do this in Rails as well you can do something like this in your controller: after_filter :set_access_control_headers def set_access_control_headers headers['Access-Control-Allow-Origin'] = '*' headers['Access-Control-Request-Method'] = '*' end

  • jQuery slideDown() not animating (jquery-rails 3.0.4; jquery-ui-rails (4.0.5)

    - by Michael Guren
    I am following along in the latest Agile Web Development with Rails 4 book. In Chapter 11 (AJAX), the book instructs us to use the following code in the "create.js.erb" file: if ($('#cart tr').length == 1) { $('#cart').show('blind', 1000); } This code causes the #cart div to jump down without any content. After 1 second it appears. There is no sliding effect. I tried using slideDown(); as well, but the div just appears immediately. Out of curiosity, I tried slideUp(); when the div was visible. Voila. The div slid up. This appears to be a jQuery bug and wondered if anyone else has experienced this, or has any suggestions for me. Thanks.

  • Showing pagination with only single page using will_paginate

    - by James
    I'm using will_paginate as standard, but it only shows the pagination controls (< 1 2 etc) when there's more than one page to display. Normally, this would be what is wanted, but I want to see the pagination controls (for UI consistency and to get round an annoying CSS quirk in the system I'm working on) even when there's only 1 page to display (showing < 1 ). Is this possible?

  • Get content from HTML element in Rails

    - by Ignace
    Hey, I'm looking for a way to get the content of my div in my Rails view. I would like the literal HTML content, so only HTML and no Rails I thought inner_html would work, but I get a RJS exception (TypeError: $("content").innerHtml is not a function) Does anyone know how I can get the content? Thanks!

  • validation before ajax form submission

    - by ZX12R
    How do i introduce validation before remote_form_for submits? I have javascript function called validateForm(). I am able to call it before the AJAX request process. I tried to use return false and event.preventDefault. But there seems to be no effect. Here is what my code looks like <% remote_form_for :customer, :update =>"uxScreenLoaderDiv", :url => {:action => "login", :controller => "site"}, :html => {:id => "uxLoginForm"}, :onsubmit => "validateForm(event)" do |f| %> User name : <%= f.text_field "uxUserName", :class => "TextBox", :style => "width:100px;" %>&nbsp;* &nbsp;Password : <%= f.password_field "uxPassword", :class => "TextBox", :style => "width:100px;" %>&nbsp;* <%= f.submit "Go!", :class => "Button-Simple", :id => "uxSubmitButton" %> <% end %> the javascript function is simple as follows function validateForm(event){ return false; //event.preventDefault(); }

  • rake test and test_structure.sql

    - by korinthe
    First of all, I have to run "rake RAILS_ENV=test ..." to get the test suites to hit my test DB. Annoying but ok to live with. However when I do so, I get a long stream of errors like so: > rake RAILS_ENV=test -I test test:units psql:/path/to/project/db/test_structure.sql:33: ERROR: function "armor" already exists with same argument types [and many more] It looks like some DB definitions are getting unnecessarily reloaded. I can't find any mention of this on Google, so I was wondering whether others have seen this? I am using a PostgreSQL database with the following in my environment.rb: config.active_record.schema_format = :sql and using Rails 2.3.5 with rake 0.8.7.

  • Should I send patch against 2-3-stable or master

    - by Nadal
    I am trying to find a way to contribute back to rails. I was thinking I should validate if this patch https://rails.lighthouseapp.com/projects/8994/tickets/4154-expires_now-broken works or not. I was able to validate the problem. The problem still exists in 2.3.5 and in 2-3-stable branch of rails. I was not able to apply his patch at 2-3-stable branch of rails . Also the patch failed for master branch. Looked at the diff and manually changed the code and the new code solves the bug. Now if I want to attach my patch to the ticket should I create my patch against 2-3-stable branch or master branch? I believe master is more closely aligned with rails3 changes.

  • Open source equivelants to VS / web reference proxy classes?

    - by seraphym
    As an ASP.NET developer, I'm used to working with how VS/C# transparently autogens proxy classes for web references (yes, I know, we're spoiled), but now that I'm creating documentation for more than one coding platform I'm trying to discover what the equivelant to that is in any other framework. So is there a similar way to work transparently with web reference proxy classes for say, RoR, PHP, and Python? And if there's nothing integrated, are there tools you recommend to autogen the proxy classes, or do you recommend to roll custom classes?

  • Forms blank when rendering a partial when using a collection of objects. Help!

    - by dustmoo
    Alright, I know my title is a little obscure but it best describes the problem I am having. Essentially, I have a list of users, and want to be able to edit their information in-line using AJAX. Since the users are showing up in rows, I am using a partial to render the data and the forms (which will be hidden initially by the ajax), however, when the rows are rendered currently only the last item has it's form's fields populated. I suspect this has something to do with the fact that all the form fields have the same id's and it is confusing the DOM. But I don't know how to make sure the id's are unique. Here is a small example: In my view: <%= render :partial => 'shared/user', :collection => @users %> My partial (broke down to just the form) note that I am using the local variable "user" <% form_for user, :html => {:multipart => true} do |f| -%> <%= f.label :name, "Name*" %> <%= f.text_field :title, :class => "input" %> <%= f.label :Address, "Address" %> <%= f.text_field :address, :class => "input" %> <%= f.label :description, "Description*" %> <%= f.text_area :description, :class => "input" %> <% end -%> When the html is rendered each form has a unique id (for the id of the user) but the elements themselves all have the same id, and only the last user form is actually getting populated with values. Does anyone have any ideas?? :) Thanks in advance!

  • Setting new class variables inside a module

    I have a plugin I have been working on that adds publishing to ActiveRecord classes. I extend my classes with my publisher like so: class Note < ActiveRecord::Base # ... publishable :related_attributes => [:taggings] end My publisher is structured like: module Publisher def self.included(base) base.send(:extend, ClassMethods) @@publishing_options = [] # does not seem to be available end module ClassMethods def publishable options={} include InstanceMethods @@publishing_options = options # does not work as class_variable_set is a private method # self.class_variable_set(:@@publishing_options, options) # results in: uninitialized class variable @@publishing_options in Publisher::ClassMethods puts "@@publishing_options: #{@@publishing_options.inspect}" # ... end # ... end module InstanceMethods # results in: uninitialized class variable @@publishing_options in Publisher::InstanceMethods def related_attributes @@publishing_options[:related_attributes] end # ... end end Any ideas on how to pass options to publishable and have them available as a class variable?

  • Rails: Creating subfolders in model?

    - by keruilin
    I'm going to have a ton of subclasses, so want to organize them under a subfolder called stream. I added the following line to the environment.rb so that all classes in the subfolder would be loaded: Rails::Initializer.run do |config| ... config.load_paths += Dir["#{RAILS_ROOT}/app/models/*"].find_all { |f| File.stat(f).directory? } ... end I thought this would solve the issue in which by convention the model class is namespaced into an according module. However, when I try to call one of the classes called stream in the stream folder, I get the following error: NoMethodError: undefined method `new' for Stream:Module from (irb):28 from /usr/local/bin/irb:12:in `<main>' Here's the model for the parent and one child: class Stream end class EventStream < Stream end Any idea what the issue is?

  • "rake test" doesn't load fixtures?
