Put this Nazi-lover on ignore immediately!

It really depends on what approach to multitenancy you want to take. If you're using scoping, you will need to make some sort of script that goes through the following steps:

Extract a backup from Heroku
Import the backup into a staging database on your local machine
Set the site id on all multitenanted tables to whatever site id you're working with
Repeat for each of your clients

If you're using schemas to seperate data, you could take a similar approach, but move tables to new schemas with ALTER TABLE after moving them over.

In any case, it's not going to be a trivial migration and you should plan for some downtime when doing it.

To be honest, if expanding beyond 5-10 sites seems like a possibility, and particularly if you want some interaction between different clients, I would probably look into using a library from the start. Getting apartment up and running really isn't all that complicated (set up a config file, and remember to use rake apartment:migrate instead of rake db:migrate and you're set.)

I'm heading to Seattle in mid-January, staying with friends and getting settled. I can't seem to find much about the area ruby-wise except Seattle.rb and a rails meet up. Can someone tell me what it's like around that area for rails and-or ruby work?

Be advised with the multi-schema approach: when you start getting into the several thousand relation (each schema gets its own copies of each table) range, pg_dump breaks and makes everyone sad.

Is ActiveResource really as goddamn slick as it seems? Automatically map REST resources from an external API to models in my application? :aaa:

what do you mean by this? as far as I can tell it doesn't require ActiveResource on the web service's end, just REST resources with JSON or XML representations. the big caveat I see to ActiveResource is that there's no baked-in OAuth support, and almost every interesting public-facing REST API (Twitter, Flickr) requires OAuth

Every time I've used it's seemed like more work than just grabbing a gem for the service.

So Heroku is deprecating "cron" in favor of daily, hourly, and decaminutely commands. Is there a good way to turn the hourly version of these into something cron-like, with day-of-week/day-of-month matching, de-repetition, etc.?

If you want super fine control, the best way is always going to be a clock process type in Procfile and something like clockwork. The obvious downside is that it's an additional dyno, so it's not free.

If you're using the scheduler addon, and want something different than what it offers you have some tradeoffs. The important thing to keep in mind is that it makes it's best effort to call your app every [whatever] time period, but it can slip. So if you keep a table of job types and the next time they are supposed to run. Then have your scheduler process check for which ones have a date less than now, run them, and update their next time.

That's pretty good, but it doesn't solve the issue if scheduler is down for an entire sunday. If instead you set the next time to run the weekly_mail task, when scheduler is back up on monday, you will know you still need to run that task.

That said, it's extremely unlikely that scheduler would be down for an entire sunday but there is nothing special about scheduler�it's just a heroku app.

Yeah, this is just a short-term thing; once we start doing recurring billing we'll probably move to clockwork or something else more robust.

If you have any of the following problems:

"rails server" doesn't work.
"gem install <any>" doesn't work.
"rake db:migrate" doesn't work

And you are completely confused by the problem and the error codes don't make sense... Uninstall and reinstall XCode.

A shameful amount of times, this has worked for me. Very frustrated with Apple right now; tying their compilers to the health of your XCode installation is absolutely painful, especially since my download speeds suck.

I spend more time fighting with ActiveResource than any other part of Rails. Of course, I'm trying to make it do crazy things like use non-numeric IDs. I have enough trouble getting it to work between two Rails apps, I wouldn't even bother trying it against a third party API.

The short version is: use http://git.io/osxgcc to install GCC, http://git.io/rbenv (and ruby-build) to install Ruby, Bundler to manage gems with your Rails projects, and http://pow.cx as your developer-mode app server.

My current customer has two apps that talk to each other. Whenever I cloned them from github, I just ln -s `pwd` ~/.pow in each one's folder, set the API_URL in the settings file of one of them, and that's pretty much it.

It's easier for me to set up on a new machine than Passenger, does the right thing with rbenv (and tried to with rvm but wayne :argh:

), and tbqh I just like hitting a .dev url and having the app run.

I just use passenger plus the preference Pane. We have 20 apps and it's easier than starting whatever one I need to work on for five minutes. Drag and drop the folder of the project onto the pane and bam.

I guess that's the answer, both to pow and passenger pref pane: You have several apps that you need running all the time. I just work on one at a time, so I don't need that.

Does either of them support Procfile to get your workers, clock, etc, up and running too?

No, but if you know node.js ( :barf:

I'd just use MailChimp for the mailing list, and maybe use some crummy blog plugin to put it on your site with comments and such. MailChimp does RSS-to-email if you want to push mails out with your blog editor.

I should clarify: I mean the type of mailing list where lots of people can contribute and it's mailed to everyone on the list. I know, old school, but these people are old and love their mailing lists.

I'm trying to put together a community type website for them and jam a mailing list/forum onto it without reinventing the wheel.

Need a refresher in object oriented programing. When working with spec, when am I supposed to use an "end" statement? Here is what I've been doing.

describe "GET 'stuff'" do

it "should have some stuff" do
.
.
.
end

it "should have some more stuff" do
.
.
.
end

it "should have the rest of the stuff" do
.
.
.
end
end

Is this the right format for end statements? Each "it should do" statement has an end, and the final end statement ends the description. Do I have it right?

Yes. While I love rspec, it's exceedingly complicated, so I'd focus learning OO not from how rspec works, but the code you're testing. Treat the rspec as incantations for now.

If you're interested though, the do..end placement doesn't have much to do with OO directly. Both describe and it are methods. They take one argument�a string that is the description�and a block. The block is code that is either surrounded by do...end or curly braces.

Ok, this clears things up a lot. I was overcomplicating rspec in my head as if, "It can't be this simple."

You still need to explicitly require the module.

So you have to require the file and then include the contents? That makes sense.

The require works but trying to include TestModule causes the baffling error "undefined method `include'". I mean that seems like a fairly fundamental method to be missing, surely?
