What libraries do you use for stemming? I've looked at Snowball-stemmer, but it tends to be unusable for general use, as it overstems the pretty much everything. For example,

football -> footbal
specifically -> specif
verifications -> verif

...and those are just three words off the top of my head.

I looked also at KStem, which seems to be less agressive, but it looks like nobody has ported it to Ruby yet. I'll probably do it myself tomorrow, if anyone doesn't have any better ideas.

Pushing a db is coming back with a timestamp error (postgres). Research has dictated that its because im using 1.9.3 and cedar stack only lets you push dbs from 1.9.2 for some unknown bullshit reason.

Any ideas?

Use PGBackups instead of db:push/puill. https://devcenter.heroku.com/articles/pgbackups#importing_from_a_backup Taps needs to die. It's a fantastic geewiz demo, but it has a lot of problems :smith:

Also if you use the new heroku-postgresql:dev plan, you can just psql straight in and/or use pg_restore from your machine.

Once everyone is on that, could probably switch push/pull to just use pg_restore under the covers.

Bob Morales: Aug 18, 2006; ~~Just wear the fucking mask, Bob~~

I don't care how many people I probably infected with COVID-19 while refusing to wear a mask, my comfort is far more important than the health and safety of everyone around me!

Any suggestions as far as load testing tools go? We had an issue the other day, our daily emails went out in the middle of the day instead of the middle of the night, and we got a huge traffic spike (from links in the emails). One of our apps has a dynamically generated menu, and the 'recipe of the day' and another similar link were being dynamically created instead of being cached. Combine 10,000 users trying to hit the site in a 20 minute period and a slow query to build the link and the site was basically unusable for a while.

I'm going to start by giving this a read:

http://guides.rubyonrails.org/performance_testing.html

I was going to write a script that I can give a list of users/passwords to and have it login then click a few links, and run x amount of those per minute.

I figure there's probably 10 tools out there that can do this already but it might be fun to write one.

We've fixed that issue (and have a list of others from NewRelic data) but I'm pulling for hitting a production app with some traffic BEFORE we let customers go at it. It seems like the last 3-4 new applications we put on the server have had issues like this at launch.

code:

require "rubygems"
require "nokogiri"
require "openssl"
require 'open-uri'
 
 # ignore SSL errors from staging server
 OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE
 doc = Nokogiri::HTML(open("https://staging.myapp.com/login/"))
 
# get the authentication token
 puts doc.xpath("//meta[@name='csrf-token']/@content")

Alright, so this can get the auth_token, and I can supply the username and password from a file . But what do I need to use to PUT the login request to the server so I can log in?

After that I'll choose some links to randomly 'click' on, and that's all I really need to do (times a thousand)

You could try combining third party solutions such as NewRelic for the measurement and blitz.io for the dummy users. I don't think you're going to get blitz.io to do logins, but it's good for just brute force testing of your resources.

It was pretty easy to do with mechanize:

code:

require "rubygems"
require "mechanize"
require "openssl"
require 'open-uri'
require "net/http"

# ignore SSL errors from staging server
OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE
I_KNOW_THAT_OPENSSL_VERIFY_PEER_EQUALS_VERIFY_NONE_IS_WRONG = nil

agent = Mechanize.new
 
target_url = 'http://test.website.com/login'
auth_email = 'bob@website.com'
auth_password = 'password1'

username_input_field = 'auth[email]'
password_input_field = 'auth[password]'

page = agent.get(target_url)
login_form = page.form_with(:action => '/login')

login_form.field_with(:name => username_input_field).value = auth_email
login_form.field_with(:name => password_input_field).value = auth_password

page = agent.submit(login_form, login_form.buttons.first)

page = agent.page.link_with(:href => '/news').click
page = agent.page.link_with(:href => '/live_talk').click
page = agent.page.link_with(:href => '/home').click
page = agent.page.link_with(:href => '/logout').click

So then I just opened up a couple terminals on a few machines and ran that script 10 times each and watched the traffic. Now I'm just working on adding some features.

* Take a CSV file of user, password, subdomain
* Command-line options for number of total times to run and how many in parallel
* Definition file for the site (our sites are similar but have evolved over the last 2-3 years and have slight changes)

Can anyone suggest a good Ruby book for someone who has a reasonable CS background and recent python experience but next to no ruby experience? I just took a job where I'm going to be doing a fair amount of it, and I like to have physical hard copies of a book or two when I'm trying to pick something up.

Design Patterns for Ruby might be good if you're familiar with GoF stuff and would like to see how it's implemented in Ruby. It goes over syntax at the beginning but at a rate that would probably be appropriate for someone with other languages under their belt already.

If you do get a book make sure it's really recent. Even stuff that covers 3.0 won't have the asset pipeline which is pretty drat important. Rails is still moving really fast and some of the stuff that's written in the earlier books is flat out wrong now.

The PragProg rails book is current for Rails 3.2, at least in ebook form. (Disclaimer: not a rails expert, for all I know the book has taught me many bad things.)

I'd also whole-heartedly endorse the pickaxe book for general Ruby education.

I'm afraid I don't really know how to ask for this properly, but here it goes.

I would like to provide users with the ability to use different view layouts based on their user settings, what would be the best way to accomplish this? ( similar to what Facebook & twitter has done recently )

So far my google-fu has not produced many results, and after reading the API on layouts and templates I feel I may be missing something fundamental.

Edit: from the layouts and rendering guide

code:

class ProductsController < ApplicationController
  layout :products_layout
 
  def show
    @product = Product.find(params[:id])
  end
 
  private
    def products_layout
      @current_user.special? ? "special" : "products"
    end
 
end

Where it will use the layout file in your "app/views/layouts/" folder.

If you want to use a specific view file rather than a layout you can mess around with render :template in your action.

I've decided to push my rails app to github to start building my 'portfolio'. I created a yaml file with all my configuration settings (passwords, email addresses, secret keys, etc) and added it to my .gitignore so that it wouldn't get pushed to github - revealing my passwords, etc.

My question: Now that git is ignoring my configuration settings, how do I successfully push app updates to Heroku without removing 'config.yml' from my .gitignore file?

Removing my configuration file from .gitignore, telling git to start tracking my config.yml again, THEN pushing to Heroku? Seems like that would be WAY too complicated. There must be an easier way, right? What am I missing?

For heroku you usually use environment variables instead of yml files, check out documentation for "heroku config" on how to add them to your heroku environment.

    themes
      theme1
        images
        stylesheets
        javascripts

I'm slowly going through Rails Tutorial Book and am enjoying it so far. The guide, and everyone else, recommends Heroku which sounds pretty awesome.

My issue is that I have my own dedicated webserver that I used to run a bunch of my other stuff. It's running apache and a whole slew of other stuff that I just throw on there whenever I feel like it. Since I'd like to utilize what I have available, what sort of configuration do you think I should use to set up my production environment so I can deploy to there instead of Heroku?

I want to mess around with Susy 1.0.rc.0 but it requires the alpha compass release v0.13.alpha.0. unfortunately they stripped regular compass of its rails integration starting in v0.12, and instead rely on compass-rails, which has not updated to the alpha release.

Any ideas? I keep getting this error:

File to import not found or unreadable: susy

Never mind, found a release candidate of compass rails.

Thanks tima and Pardot. I'm looking into Foreman and .env now.

EDIT: I successfully got Foreman running locally. I added all my config vars (which were spread across two separate yml files!) to one .env file in my root and added that to my .gitignore. Deleted all my config.yml files, committed, & pushed to Github painlessly. That's much better! Thanks guys!

My Foreman Procfile is pretty empty
web: rails s test: rspec

I'm not too keen on the lack of color formatting in my terminal output after running rspec. Though I understand that can be fixed if I also install and configure Guard for autotests.

For now, is there any way I can run rspec in pretty colors without Foreman, but still load in my testing environment variables from .env? I'm guessing no.

What other things can I do with Foreman that might be useful?

Strong Sauce: Jul 2, 2003; You know I am not really your father.

So I have 2 model types, Leagues and Players. Leagues can have Players, and Players can be in different Leagues.

You can add players and leagues separately, but I'm trying to assign an already created player to the current league. Before I would just do League.find(params[:league_id]).players.create(params[:player]) to add players to a league, but that method doesn't help me much for existing players.

Essentially what I want to do is just add into the join table that player with :player_id is now also in league :league_id. But I don't want a new entry in the player table.

I haven't done Rails in a while so I'm blanking out here. Any help?
