I thought that

code:

<%= ... =%>

inserts the result of evaluating the expression inside the tag into the resulting HTML while

code:

<% ... %>

is for control/flow and other code that doesn't write to the document.

Yes but with old erb if you did <% if cond %> that line would leave a blank line into the output. Doing <%- if cond %> suppresses the line. Erubis, which Rails 3+ uses, doesn't leave blank lines and the <%- is unnecessary.

I can thank my crappy low-res display for making <%= look just like <%-

I'm starting to use jQuery for the first time in Rails (first time ever, really) and I'm running into a weird problem. Does Firefox do something different than IE/Chrome when it comes to waiting for page responses? When I update some records with a jQuery remote form submit I notice that the records updated don't always reflect their changes after a page refresh in IE/Chrome but they do 100% of the time in FF. In the former browsers sometimes I have to do two page refreshes to see the changes. What gives?

Thanks. I have another question that is probably more Rails related, though, so maybe someone can still help. I'm trying to figure out how to use check boxes to select multiple records and update them accordingly depending on what button a user presses (think GMail e.g., delete, archive, etc).

There's a really great Railscasts that introduced me to this functionality but I'm having trouble figuring out how to extend it to include more than one button. He essentially uses a form that includes a checkbox and the button but I don't want to have more than one checkbox! What is the best way to go about extending this functionality to include more buttons without adding the checkboxes?

So...Rails 3.1 is scheduled to drop tomorrow. Anyone have a decent set of links for getting up to speed on things? So far I've not touched it and have just cobbled together info from the links in this 3 month old blog post. In particular I'd appreciate thorough write-ups of asset pipelines and engines.

One thing that a lot of people don't realize is that submit fields actually pass their value through to the server when they submit - I'm imagining you could do something like this pretty easily:

(view)

code:

<ul>
  <%= check_box_tag 'items[]', 1 %> Item 1
  <%= check_box_tag 'items[]', 2 %> Item 2
</ul>

<%= submit_tag "Delete" %>
<%= submit_tag "Archive" %>

(controller)

code:


items = Foo.find(params[:items])

# :commit is the default name of submit buttons in rails.
case params[:commit]
when 'Delete'
  items.delete_all
when 'Archive'
  items.archive_all
end

One caveat - if you're using AJAX to send the form you'll need to set another hidden field called commit manually, since it's not technically the submit button sending the form (even if you hook into the submit event of the form.) It's still a good approach even if you have to do this as it will degrade nicely if your user doesn't have JS running.

I know this was answered awhile back, but how can I speed up the load time of a heroku app?

Pretty sure it had something to do with installing new relic to keep your instance running... just wondering if there is another method.

Yes I am currently using a free account, and am willing to spend money to keep it running. I am / was under the impression that adding a dyno or worker would not prevent the instance from dropping.

Damnit I was going through the documentation and didn't find that. Thanks VVV

looked it up. heroku has pretty extensive documentation.

heroku dev center posted:

What is dyno idling?
Apps that have only 1 web dyno will be idled out after a period of inactivity. The web dyno will be shut down. When a request comes in to an idled app your web dyno will be automatically spun back up, causing a few second delay for this first request. Subsequent requests will perform normally.

Apps that have more than 1 web dyno are never idled out. Workers dynos are never idled out.

Put this Nazi-lover on ignore immediately!

In regards to the New Relic "trick", there's an availability monitor on NewRelic that will ping your server every 30 seconds or so - if you turn this on with a free instance, you'll never have enough idle time for Heroku to spin down your instances.

On a related question, does anyone have any hints for speeding up Heroku loadtime immediately after deploys? It's probably the biggest obstacle in our way to being able to deploy fairly continuously, since every deploy means that users are going to see a loading screen for 10-15 seconds.

Also, the migration setup is somewhat weird on Heroku - I'd really like to be able to do database migrations BEFORE deploying code (since 99% of the time they are additive, and code that doesn't know about the new columns will still happily work, whereas the converse is very rarely true.)

Not idling worker dynos is really loving annoying. I realize it's only $34/month but it's dumb to wind down the free web dyno while leaving the worker dyno up, doing absolutely nothing.

It's an interesting (read: hard) problem. The safest thing is always going to be, maintenance mode, deploy, migrate, un maintenance mode.

If you're willing to do engineering work around it though, you could write your app to work with both schemas new and old, your app can run while the migrations are running. Especially if you use a good database like postgres (which you probably are if you're on us) , the alters can run in a transaction for extra awesome. That's hard to do though, especially with active record out of the box.

Also, if you wanted, I suppose you could copy your DATABASE_URL to a second app, and run migrations off of that second app. You'd still need to make sure your code ran on both versions. lovely experience though, but something to consider.

Not sure if this is an acceptable place for general Ruby questions, but I can't find any other Ruby thread so figured I'd try here.

Looking at the source for the Net::FTP.gettextfile method (http://ruby-doc.org/stdlib/libdoc/net/ftp/rdoc/classes/Net/FTP.html#M001274), I can't see how you can end up with the "localfile" argument as nil. Am I missing something here?

I'm trying to use that function to return the contents of a file from the FTP server into a variable rather than write it to a file. The comment for the function says "If localfile is nil, returns retrieved data" and it looks from the source like the intention is there to be able to do this, but I can't see how you can do this given that it sets localFile = File.basename(remotefile) in the argument list.

I thought I might be able to do gettextfile(my_remotefile, nil), but ruby complains about converting "nil" to a string.

Which version of Ruby are you using? That documentation link from your earlier post is for 1.9. In 1.8, #gettextfile doesn't have the option of not writing to a file and passing nil would result in the error you're getting.

e: But in 1.9 what you're attempting would work.

Default arguments only happen if the argument isn't given, not if it's nil.

What's the best way to pick up the documents and embed them into their parents-to-be? The object IDs correspond to files stored on Amazon S3 so I certainly don't want to lose those.

This is from another dev who I've been trying to troubleshoot the issue with:

Rails 3.0.7 (new app 1) uses considerably more memory than Rails 3.0.9 (new app 2) -- but neither is as good as Rails 2.x or 1.x in terms of memory usage.

For example, after serving 333 requests, one <old app> process (a Rails 2.x app) is using 69MB of RAM. On the other hand, after serving 64 requests, one <new app 1> orocess (a Rails 3.0.7 app) is using 207MB of RAM. I chose those two apps because they have so much in common that it seems like the only difference is the Rails framework.

I set passenger to kill (new app 1) processes after 75 requests. It looks like a bunch of memory is eaten on each request and it's not released. But if you kill the process, then the OS will reclaim the memory.

No idea what's causing it though. It's (new app 1)-specific because (new app 2) is a Rails-3 app that does not have any problems.

Memory leak of some sort? Garbage collection??

Rackspace wants a good-sized amount of money to add another 24GB to our server (split into 12gb app, 12gb db VM's)

But if we signed up another big customer or deploy a third rails 3 app, we'll just be eating up a ton more memory anyway.

Cocoa Crispies: Jul 20, 2001; Vehicular Manslaughter!; Pillbug

What Ruby implementation? 37signals uses 1.9.3dev to get tunable garbage collection for speed; REE has the same tuning options but is 1.8.7. Either of these will be better with Passenger than straight 1.8.7 or 1.9.2 due to the way gc and forking interact.

You might also want to test a different app server configuration; passenger has lots of knobs and dials you can play with, and unicorn has some too.

Finally, there's a reason lots of apps just go to Heroku; scaling is done by adjusting a "how much money you want to spend" slider in real-time.

Ruby retains and reuses its allocated memory, so if you need 200MB of memory at one point in time, the interpreter will allocate that and not release it back to the system. Make sure you're not doing anything like loading thousands of rows into ActiveRecord instances, or reading entire images into memory; stuff like that.

I am looking at setting up memprof right now, I'm just not sure what could I should be checking (or what the easiest way to check all of it is)

Signaled process 26502 with SIGURG
Waiting 30 seconds for process 26502 to create a new dump...
Usage:
    -p, --pid <pid>                  PID of the process to dump       (required)
    -n, --name <name>                Name for your dump               (required)
    -k, --key <key>                  Memprof.com API key              (required)
    -d, --[no-]delete                Delete dump file after uploading (default true)
    -s, --seconds <seconds>          Seconds to wait for the dump     (default 300)
    -t, --[no-]test                  Test run (don't actually upload) (default false)
    -f, --file <path>                Upload specific json dump        (optional)

                                     internal data on the internet    (required)
        --info

Timed out after waiting 30 seconds. Make sure you added require '/usr/local/lib/ruby/gems/1.8/gems/memprof-0.3.10/lib/memprof/signal' to your application.

I put the 'require memprof' line (like it is in the error message) as the very first line in my environment.rb - is there something else I have to do other than a touch tmp/restart.txt?

Also memprof.com isn't working so I don't know if that's part of the error, I'm trying to just get it to dump to a file by giving a made-up key and using the -f option
