Although I wish that the latest trend in shoving javascript into loving EVERYTHING will go away, like having it be the front-end to your database store that these new and shiny NoSQL things have. What the HELL.

Which database is that? The only NoSQL database I am aware of that even comes close to using Javascript is CouchDB, and even there Javascript is just an option. You can use any language you want to create your views, including Ruby.

I do a lot of couchdb, and I don't know anyone who doesn't just use the built in javascript. But you're right that you can plug in different view engines.

I wrote a CouchDB adhoc query indexer that is a mixture of Ruby and C, but yeah, I see no reason not to use Javascript for regular views. It is the easiest way to work with JSON.

Secx: Mar 1, 2003; Hippopotamus retardus

I'm trying to parse an HTML file using Hpricot, but I'm having issues extracting "free floating" text which is not enclosed in tags like <p></p>.

code:

require 'hpricot'

text = <<SOME_TEXT
  <a href="http://www.somelink.com/foo/bar.html">Testing:</a><br />
  line 1<br />		
  line 2<br />
  line 3<br />
  line 4<br />
  line 5<br />
  <b>Here's some more text</b>
SOME_TEXT

parsed = Hpricot(text)

parsed = parsed.search('//a[@href="http://www.somelink.com/foo/bar.html"]').first.following_siblings
puts parsed

I would expect the result to be

code:

<br />
line 1<br />		
line 2<br />
line 3<br />
line 4<br />
line 5<br />
<b>Here's some more text</b>

But I am getting

code:

<br />
<br />
<br />
<br />
<br />
<br />
<b>Here's some more text</b>

Is following_siblings not what I should be using here?

The text aren't elements, so I guess they don't count as siblings.

code:

>> pp parsed.search('//a[@href="http://www.somelink.com/foo/bar.html"]').first.following
#<Hpricot::Elements[{emptyelem <br>},
  "\n  line 1",
  {emptyelem <br>},
  "\n  line 2",
  {emptyelem <br>},
  "\n  line 3",
  {emptyelem <br>},
  "\n  line 4",
  {emptyelem <br>},
  "\n  line 5",
  {emptyelem <br>},
  "\n  ",
  {elem <b> "Here's some more text" </b>}]>

_{You can make Javascript decent but why bother when there's Lua, IO, Lisp and much better functional languages about}

If the first HTML scripting language had been Lisp we would be living in a different world man - I am so serious.

But since that has not happened, Lisp has piss poor support and tooling (compared to, say, python), IO is too young to be taken seriously and Lua is, well Lua is good but it's not actually thaaat much better then JavaScript and JS just has a lot more momentum and mindshare.

Actually other then syntax and a few narrow and specific nit-picks (like boolean casting) there is exceedingly little to hate about JS.

We really could do a lot worse then JS!

I'm in the middle of a project and the guy I'm working with has been putting all of the database information straight into the production database. Nevermind if this is a good idea or not, is there a way to pull all of this information into the development database? The production database is Amazon RDS, and I'd like to use SQlite for development if possible.

I was at the announcement keynote, and Benioff swore up and down that they're commited to not touching Heroku culture, but really everyone says that and we'll have to wait and see.

One thing that could be interesting is if they pull off database.com and get it well integrated to heroku. One thing that I don't think Heroku has ever pulled off super well is a good database story - it's fine for small stuff but when you get into bigger stuff (particularly at the enterprise level) it's a bit too inflexible for my tastes.

You can use Amazon SimpleDB, RDS or MongoHQ with Heroku if you like, though. Heroku's philosophy is why do something when others can do it much better?

Yeah, that's true. I guess what I'm saying is that I think database.com is a bit more compelling on it's own. It's probably due to working more in the enterprise space, but having a solution for multitenancy baked right into the product is amazing.

Im almost finished making this Rails 3 CMS for someone, but Im trying to set it up so he can update his contact email and have the mailer use that user defined email address to send mail to.

Right now I have this in my mailer

quote:

@email = SiteSetting.first

default :from => "requests@innerquestonline.com", :to => @email.email
default :subject => "Inquiry From InnerQuestOnline.com"

def support_notification(sender)
@sender = sender
mail
end

which works fine on my local machine, but it crashes on heroku. Herplu doesnt seem to like calling the email field. Is there another way I should be doing this?

Nolgthorn: Jan 30, 2001; The pendulum of the mind alternates between sense and nonsense

I am having trouble wrapping my mind around how much more simplistic my application is expected to be using Mongoid rather than ActiveRecord. With AR, it felt like having a controller without a matching Model was extremely uncommon. But now it actually is starting to feel as though there is a distinct separation between the layers and the different purposes they are meant to have.

Every second or third model I am ending up re-writing around now, because I'm discovering I no longer need them.

Actually switching from AR to Mongoid is taking a really long time because I am having to re-learn everything I used to know about database best practices.

For a while I was getting confused about why I was meant to rely so heavily on inheritance. But it makes sense, inheritance in Mongoid fixes the following things about AR:

1) Long query times, includes, joins, etc. In general the database does far fewer writes than queries. Mongoid encourages you not to spend a lot of time building complex queries, but instead to just put the data you will need, into the correct places to begin with. Complex writes over complex queries. By using class (model) inheritance, you eliminate all 'polymorphic/habtm/has-many through' and join tables. You don't ned them anymore because any model is actually any other model or vice versa and can be grabbed just by being where you need it.

2) You may have a model that very simply stores an address. You can now take that and embed it anywhere you want without having to worry about load.

3) No more empty fields stored of any kind.

4) Ability to store ANYTHING.

5) i dunno, something.

I am having more problems with having to rewrite code than I was before, but that's because I am updating the application to work much more elegantly while utilizing far fewer models and certainly far fewer 'collections' (tables).

I am stripping out almost everything! It's almost like most of my workload shifted from writing code to interact with the database, to removing all of it.

This is getting ridiculous.

For instance I want to keep track of other users for each user. I used to have a table that stored those relationships but it isn't necessary anymore. I don't even need a second model. For any characteristic that I want to store about the relationship with the other user, the application just now stores two arrays of ids it keeps up to date for me.

Thanks guys that optimization slideshow is probably going to be really helpful later on. But I did something horrible and unforgivable to my environment and now I am regretting it.

The steps I took were approximately:
1) [start over remove all rvm'd ruby directories.]
2) rvm install 1.8.7
3) rvm 1.8.7 --default
4) gem install bundler
5) bundle install

Yeah then it works fine, it's faster than ever. This all started after I performed a restart, maybe I don't have mongoid set up as well as I thought I did.

I need to look into mongodb's settings and whatnot.

My friend (not me) is looking for a RoR dev for something that may well end up open source. The pay is market rate. It's a community sharing type site, he has a fairly clear idea of what he wants with wireframes/mockups etc. That is about all I know, you can get more details from him by sending a mail to dani.mcgoo@gmail.com with your cv and some samples.

I am seeking some kind of link related method that will extract information from external pages via url input. So, if it were a youtube link, perhaps it would return some thumbnail urls and a description. Vimeo would be similar and twitter posts would be, like the content of the twitter post. Things like that?

Something general, that helps assert what may be the content of the link. It would be great if it used apis where available, and otherwise best-guessed at the content of the page.

I've started something myself. In case there truly is not another case of this being attempted already, but I'm hoping a further along version is available.

code:

  def url_parse(url)
    if video = url.match(/http:\/\/(www.)?vimeo\.com\/([A-Za-z0-9._%-]*)((\?|#)\S+)?/)
      return {:website => "vimeo", :id => video[2]}
    elsif video = url.match(/http:\/\/(www.)?youtube\.com\/watch\?v=([A-Za-z0-9._%-]*)(\&\S+)?/)
