  • I want multipart/alternative; ActionMailer only sending text/html

    - by macek
    I'm following the Ruby on Rails Guide: ActionMailer Basics Section 2.7 Snippet: Action Mailer will automatically send multipart emails if you have different templates for the same action. So, for our UserMailer example, if you have welcome_email.text.plain.erb and welcome_email.text.html.erb in app/views/user_mailer, Action Mailer will automatically send a multipart email with the HTML and text versions setup as different parts. Well, I have both: app/views/user_mailer/welcome_mail.text.html.erb app/views/user_mailer/welcome_mail.text.plain.erb app/models/user_mailer.rb class UserMailer < ActionMailer::Base def welcome_mail(user) recipients user.email from "[email protected]" subject "Thanks for registering" body :user => user end end Any luck?

  • Sqlite3 activerecord :order => "time DESC" doesn't sort

    - by Ole Morten Amundsen
    rails 2.3.4, sqlite3 I'm trying this Production.find(:all, :conditions = ["time ?", start_time.utc], :order = "time DESC", :limit = 100) The condition works perfectly, but I'm having problems with the :order = time DESC. By chance, I discovered that it worked at Heroku (testing with heroku console), which runs PostgreSQL. However, locally, using sqlite3, new entries will be sorted after old ones, no matter what I set time to. Like this (output has been manually stripped): second entry is new: Production id: 2053939460, time: "2010-04-24 23:00:04", created_at: "2010-04-24 23:00:05" Production id: 2053939532, time: "2010-04-25 10:00:00", created_at: "2010-04-27 05:58:30" Production id: 2053939461, time: "2010-04-25 00:00:04", created_at: "2010-04-25 00:00:04" Production id: 2053939463, time: "2010-04-25 01:00:04", created_at: "2010-04-25 01:00:04" Seems like it sorts on the primary key, id, not time. Note that the query works fine on heroku, returning a correctly ordered list! I like sqlite, it's so KISS, I hope you can help me... Any suggestions?

  • Is there a way to make the flash[:notice] appear above, or before, the flash[:error] ?

    - by GoodGets
    So, I'd like to be able to display both a flash[:notice] and a flash[:error] on the same action, but I'd like for the :notice to always be displayed above (or before) the error. Is there a way to do this? In my controller, I thought I could just code the flash[:error] before the flash[:notice], so that rails will display it correctly, and it does a vast majority of the time. But every now and then they are randomly switched, and I can't seem to figure out why. So, how can I ensure that a flash[:notice] is always displayed above an :error ?

  • 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!

  • 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?

  • Help getting ActiveScaffold to work properly

    - by x3ro
    Hey there I was curious about the ActiveScaffold Rails plugin, but somehow I can't get it to work properly. I've followed the steps which are described on http://activescaffold.com/tutorials/ . The table and everything shows up and when I click on "Create new", the dialog pops up. However, when I fill out the form and click "Create", I just get "500 Internal server error". In the server log, it says "NameError (wrong constant name ###):", with ### being what I entered in the first form field. If I don't enter anything in the form, it says "NoMethodError (undefined method `new_record?' for #):"... So what am I doing wrong here? Thanks in advance for your help :)

  • problem with parsing string from excel file

    - by ohana
    hi, i have ruby code to parse data in excel file using Parseexcel gem. I need to save 2 columns in that file into a Hash, here is my code: worksheet.each { |row| if row != nil key = row.at(1).to_s.strip value = row.at(0).to_s.strip if !parts.has_key?(key) and key.length 0 parts[key] = value end end } however it still save duplicate keys into the hash: "020098-10". I checked the excel file at the specified row and found the difference are " 020098-10" and "020098-10". the first one has a leading space while the second doesn't. I dont' understand is it true that .strip function already remove all leading and trailing white space? also when i tried to print out key.length, it gave me these weird number: 020098-10 length 18 020098-10 length 17 which should be 9....

  • Correct way to safely store token/secret/etc from OAuth?

    - by viatropos
    I just started looking into OAuth and it looks really nice. I have oauth with twitter working in ruby right now. Now I'm wondering, what is the recommended safe way to store the responses in my local database and session? What should I store? Where should I store it? This example twitter-oauth-with-rails app stores a user.id in the session, and the user table has the token and secret. But that seems like it'd be really easy to hack and get the secret by just passing in a slew of test user ids, no?

  • Git + Capistrano = Automatic Release Notes Generator ?

    - by Matt Rogish
    We use git (github) and capistrano (like 99% of the Rails shops out there) to deploy our app to production. What I'd like to do is, after every cap * deploy generate a text file containing all the git commit comments since the last deploy. I can then take that list of commit comments, clean it up, and put it somewhere for consumption. "git log" http://book.git-scm.com/3_reviewing_history_-_git_log.html has plenty of options for fetching log messages, but I don't see an easy way in capistrano to return the current and previous commits, or even the last date/time a deployment occurred, so I can pass that to git log Thoughts? I can't be the first one doing this... Thanks!

  • Remapping design issue

    - by Sirupsen
    Hello, I'm currently developing a Ruby Gem and I'm a bit lost on the design currently. Basically, I'm remapping some APIs, so my skeleton is something like this: module MyApp module SomeApi class Function > Base::Function ... end class Function2 > Base::Function2 ... end ... end module SomeApi2 ... end class RemappedFunction def initalize # set some values and stuf ... end def remapped_method # Problem: # How would I know, if I should take contact to # SomeApi, or SomeApi2? end end def interact_with(api) # What would be the best way of letting RemappedFunction # know which API to use? end end someapi2 = MyApp.interact_with(:someapi2) someapi2.remapped_method Any ideas?

  • Using delayed_job to process file uploads across multiple servers

    - by Steve Klabnik
    Does anyone have any good resources on how to do this? Basically, I'm working on a project (in Rails) where people can upload files. They might be big. I'd like to process them using delayed_job before sending them to S3. I'd also like to do this processing on a separate job queue server, rather than on the webserver itself. I'd rather not have to upload the files to the webserver, then transfer them to the job queue server, and then upload them to S3 if I don't have to. Thanks.

  • HTML form requirements specification

    - by Peder
    I am building a framework that will validate forms both client-side (javascript) and server-side based on a form requirements specification written in json. The purpose is to get rid of logically equivalent code on the server and client to make the code more maintainable, faster to write, and less buggy. The specification format may look something like: { '&lt;field_name>' : ['&lt;validation_function>', 'req', ['&lt;requirement>', &lt;param>], ...], ... } ( the requirement list is ordered so that the user can get most basic error messages first, the 'req' requirement must come first if it exists and means that the field is required) e.g.) { 'name' : ['string', 'req', ['min',6], ['max',150], ['match', /^[\sa-z0-9ÅÄÖåäö&]$/i], ['not_match', /^tmp_/]], 'email' : ['email', 'req'], 'email_confirm' : ['same_as', 'email'], 'password' : ['string', 'req', ['min', 6], ['max', 64], ['match', /^[a-z0-9\!@#\$%^&*_+.]$/i] ], } Does anyone know of a similar technology? I think the Rails validation framework solves the problem on the wrong level because I have found that forms often operate on more than one model.

  • Generating PDF's via Delayed Job while maintaing a RESTful pattern.

    - by Jeff
    Hi, currently I am running a Rails app on Heroku, and everything is working great with exception of generating PDF documents that sometimes contain thousands of records. Heroku has a built-in timeout of 30 seconds, so if the request takes more than 30 seconds, it's abandoned. That's fine, since they offer delayed_job support built-in. However, all of the PDF's i generate follow a typical restful pattern. For instance, a request to "/posts.pdf" generates a pdf (using PRAWN and PRAWNTO) and it's delivered to the browser. So my basic question is, how do I create dynamically generated PDF's with delayed_job while maintaining the basic RESTful patterns Rail's so conveniently provides. Thanks.

  • Autotest notifications on Ubuntu virtual environment

    - by Luciano
    I am having trouble getting Rails autotest notifications to work on the Engine Yard Vagrant environment. On the Mac, I normally get the notifications via Growl. However, on the virtual environment (which runs Ubuntu) that doesn't work. I tried running Linux notification setups such as libnotify+autotest-notification, but I get the following error: libnotify-Message: Unable to get session bus: /bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed. ** (notify-send:1004): CRITICAL **: dbus_g_proxy_connect_signal: assertion `DBUS_IS_G_PROXY (proxy)' failed ** (notify-send:1004): CRITICAL **: dbus_g_proxy_connect_signal: assertion `DBUS_IS_G_PROXY (proxy)' failed ** (notify-send:1004): CRITICAL **: dbus_g_proxy_call: assertion `DBUS_IS_G_PROXY (proxy)' failed Another path would be to have Growl receive the notifications remotely, but I don't even know where to begin with that... Any suggestions?

  • How to get methods list in scala

    - by skyde
    In language like python and ruby to ask the language what index-related methods its string class supports (which methods’ names contain the word “index”) you can do “”.methods.sort.grep /index/i And in java List results = new ArrayList(); Method[] methods = String.class.getMethods(); for (int i = 0; i < methods.length; i++) { Method m = methods[i]; if (m.getName().toLowerCase().indexOf(“index”) != -1) { results.add(m.getName()); } } String[] names = (String[]) results.toArray(); Arrays.sort(names); return names; How would you do the same thing in Scala?

  • IsValidLocale returns FALSE - how to overcome this?

    - by sharptooth
    When run on a Spanish version of Windows XP my program invokes LANGID langId = (LANGID) MAKELANGID( LANG_ENGLISH, SUBLANG_DEFAULT ); LCID locale = MAKELCID( language, SORT_DEFAULT ); BOOL isValid = IsValidLocale( locale, LCID_INSTALLED ); IsValideLocale() return FALSE when asked about English locale. Obviously something must be tuned in Windows to change this behaviour. What exactly should I do? I understand that it's not completely a programming question but rather a deployment question. Still I think it will be better off here than anywhere else.

  • Scaffolding A model with an attribute of type datetime creates a 10 years range in the form

    - by b_ayan
    For a simple rails application ( 1.86 /2.3.5) , lets say I run a simple scaffold script/generate scaffold blog title:string content:text published:date When I open up the new / edit view for the blog controller in index/new.html.erb , I see that the drop down enabler for date select has a date range of 2005 - 2015 , i.e 5 years +/- I tried to change this default behavior by introducing this code f.date_select :entered, :start_year => 1970, :end_year => 2020 Apparently this has no impact to the behavior mentioned above. How do I increase the date_select range which seems to be default?

  • I want to use the fleximage gem and s3 for storage, but don't want dev/qa/test env's to use s3

    - by Kevin Bedell
    I have a rails app that I'm going to host on engineyard and want to store image files on s3. But I don't know if I want all developer machines to beusing s3 for storage of all our test and dev images. Maybe it's not an issue -- but it seems like a waste to have everyone storing all our images in s3. I've heard of some ppl who store images on s3 'hacking' dev environments to store images locally on the file system -- and then using s3 in prod only. What are other people doing?

  • Twitter @Anywhere oauth_bridge_code

    - by AngelCabo
    I'm having trouble with Twitter's implementation of an oauth_bridge_code for the @anywhere api. I've seen a few walkthrough's on how to use this functionality but I can't seem to get the request to work for me. I'm using Ruby on Rails with the oauth gem. My code is as follows: def callback consumer = OAuth::Consumer.new(APP_CONFIG['twitter_key'], APP_CONFIG['twitter_secret'], :site => "http://api.twitter.com", :request_token_path => "/oauth/request_token", :authorize_path => "/oauth/authorize", :access_token_path => "/oauth/access_token", :http_method => :post) request = OAuth::AccessToken.new consumer json = request.post("https://api.twitter.com/oauth/access_token?oauth_bridge_code=#{params[:oauth_bridge_code]}") end I keep getting 401 unauthorized responses from the signed post request even though this is supposed to be working according to this walkthrough: http://blog.abrah.am/2010/09/using-twitter-anywhere-bridge-codes.html and a presentation from Matt Harris on slideshare. Any ideas on what I'm doing wrong (besides possibly trying to hit functionality that may not be in place)? Greatly appreciated!
