Re: [Rails] root_path and root_url undefined

[Darian Shimy]

Not sure what is the issue is, I am running 2.3.4 and it works fine.
I do have he map.root as the first entry although I don't think that
will matter.

Can you send your routes.rb file?

[Rails] Re: How do I implement this? run scheduler on one of cluster?

[Freddy Andersen]

You should code your own daemon that kicks of every min or so and this
daemon picks-up jobs and finishes these and marks them done. I think
there was a screen cast over with Ryan that shows how to implement a
simple daemon. (This way you can have multiple daemons.. )

Or you could use something like backgrounDrb as a scheduler...

Re: [Rails] Rails 2.3.5 - Cannot install plugin

[Hoang Nghiem]

Thanks Niels, I created dump folder dev/null at C drive and the problem
still occur. I found a way to work around to install plugin that just copy
the plugin to the vendor folder. Any plugins that have the install hook code
can be call through rake task.

Thanks again!

[Rails] How do I implement this? run scheduler on one of cluster?

[femto]

Hello all,
How do I implement this? run scheduler on one of cluster?
I now have a requirement, needs to run scheduler on one of cluster?,
my app is monitor app, user will specify rules on my apps, like say,
invoke jmx function, find out the connection pools' count, if > 10,
then invoke some function. Something like that, and needs to run/check
every 3min.
So like say, rule1, run every 3min, rule2, run every 5min,
how do I ensure that I only run in one machine of my server cluster(my
monitor cluster)?
my monitor cluster will follow the standard rails deployment, deploy
multiple instances,
on multiple machines.

[Rails] root_path and root_url undefined

[Matt Harrison]

Hi all,

I've just started working on another RoR project after a couple of months
away. I'm having trouble with named routes, specifically root_*

In previous apps I've used root_path and root_url without any problems, but
in this project (2.3.2 - the same as my last project where I used it) it
comes up undefined.

I've double and triple checking my routes.rb, and it all appears fine. I've
defined map.root and removed index.html. I just can't think what could be
causing this continuing problem.

I had upgraded this app to 2.3.5 and thought that might have been the cause.
I googled around for deprecation notices or anything and eventually
regressed rails back to 2.3.2 with no change.

I know I've probably missed something very simple, but it's completely
eluding me right now. Any insights you guys could send my way would be
appreciated.

Thanks

Matt

No.  It does.

Google for those method names and you'll find tutorials on how it works.

[Rails] Re: error using rails_sql_views

[db_333]

Did some more digging on this and there's an issue with the gem.
you'll need to update the gem and comment out the following code:
rails_sql_views.rb:29

#unless Kernel.respond_to?(:gem)
#  Kernel.send :alias_method, :gem, :require_gem
#end

the other issue is that there is an updated version of the gem, but
it's notreleased on rubyforge.  This version takes care of the above
issue.

In either case, I now have the gem working properly


see http://github.com/aeden/rails_sql_views/issues#issue/2
for details.

That looks like someone has been using alias_method_chain - there is
no method called execute_without_analyzer. alias_method_chain renames
the original execute method to execute_without_analyzer

[Rails] Problem with activesupport version

[Srdan Dukic]

Hi,

I'm fairly new to rails development and am using Ubuntu 9.04 as my
distribution. I'm trying to get the 'authlogic_example' sample app working,
however I run into this problem when I try to install the gems neccessary.

$ sudo rake gems:install
(in /home/srdan/rails/authlogic_example)
rake aborted!
can't activate activesupport (>= 0, runtime), already activated
activesupport-2.1.0

(See full trace by running task with --trace)


The output of 'gem list' shows that I do in fact have activesupport
installed, version 2.3.4

$ sudo gem list

*** LOCAL GEMS ***

actionmailer (2.3.4)
actionpack (2.3.4)
activerecord (2.3.4)
activeresource (2.3.4)
activesupport (2.3.4)
authlogic (2.1.3)
mysql (2.8.1)
nifty-generators (0.3.0)
rack (1.0.1)
rails (2.3.4)
rake (0.8.7)
rubygems-update (1.3.5)
sqlite3-ruby (1.2.5)


What exactly is causing the problem here? Is it that authlogic requires an
older version of activesupport or is it something else? Should I uninstall
the newer version of activesupport and replace it with the older version? If
so, how would I do that?

Thank you

[Rails] Online Auction

[Eric]

I'm looking for a script or engine that can be customized.  We are
building an site that has a specialized auction as part of it's
functions.

Somethings that will be different from a regular Dutch auction are
-multiple bidders will be accepted (grouped to complete the bid) as
they will be bidding on lending and borrowing
-Auctioneer will have the right to accept or reject bids
-Auctioneer will be able to set the duration of the auction and can
close it at anytime
-Both parties can negotiate counter offers/bids
-Auction will automatically end when the total requested bid is meet

These are not features we need to be include (though any would be
nice) rather we would like to start with a base environment that can
be modified

Thanks

[Rails] Re: Submitting a form onDrop, parameters don't come through

What surprises me the most is that it submits the form (it sends a
POST request to the right place), but it doesn't submit form data. Why
is that?

I hope someone can help, I'm stuck.

[Rails] Re: bad move? - complex form with *many* observe_field's

[chris.reis...@gmail.com]

1) Depends what you have the observer do...  Sounds like you are
hitting your site every 3/4 of a second for the first hit, and 1.5
seconds after that now.  If you are doing a save every time the
observer fires.  You can write an observer to call a local function
instead of doing the AJAX save.  but they whole point of doing AJAX
saves is to send the data to the server.

2) You can observer a form..  calls a function that looks at the field
type and does different work on the change...  AKA, start a timer on
text field, or call AJAX directly on select field.  It is a simple if
else on the local JS function.

3) You could remove all existing observers and create a new observer
on every new event on a new field.  But it would be a bit complex.
maybe the onFocus() would work for everything?  Not sure.  onFocus
removers all observers, and makes a new observer for the current
field...  You would not be able to move an observer around I would
think.  But this would make it seem like you were.

[Rails] Invalid gem format, for every gem in rails

[Brian]

I've been trying to upgrade InstantRails2.0 to a more recent version
of rails.  I've updated gem to version 1.3.5. When I do a simple 'gem
update rails', I got the 'Invalid gem format' error for
activesupport-2.3.5.gem.  After researching it and finding a couple
threads here, I tried to delete this gem from the cache.  Still didn't
work, it just got re-loaded when installing rails.  I tried going to
version 2.3.3 of rails, since I don't need the latest and greatest,
and a thread here suggested a problem in the latest repository.

I tried manually downloading the activesupport-2.3.3.gem and
installing from that local downloaded gem.  This appeared to work, so
I downloaded rails-2.3.3.gem and tried to install this local copy.  I
continue to get the 'invalid gem format' for a different gem each
time.  Each time I manually download and 'gem install local' the
version that last reported the error, and each time I get the 'invalid
gem format' for another gem.

What's the root problem? I've just finally got rails 2.3.3 to install,
but I need to do this on another machine as well, and am really not
looking forward to doing this process again.

Re: [Rails] Rails 2.3.5 - Cannot install plugin

[Niels Meersschaert]

That would explain it.  /dev/null is a Unix feature.  It's possible the plugin 
install feature lost Windows support in 2.3.5 by hardcoding /dev/null.  The 
vast majority of Rails developers are on Macs or Linux, so I can't say I'm 
surprised.  You might be able to work around it by adding an empty file at 
c:\\dev\null, though since I don't develop on Windows, I can't say for sure.

RE: [Rails] Re: accepts_nested_attributes_for and belongs_to

[Joe McGlynn]

It updates both parent and child models.  The Parent model is the order, you
can change the name of the order, add and remove children (line items), etc.
I kept the data model very simple so that the basics of the form didn't get
lost.  You can use the same setup for any Model with a has_many child
relationship.

Re: [Rails] Re: Very slow Mysql in Rails 2.3 versus Rails 2.1

[BW]

Well, I've come closer to tracking down the problem.  Running only
ActiveRecord, the problem does not occur.  So I created a fresh Rails 2.3
project and started adding the plugins I use.  Turns out rails-footnotes was
causing the slowdown.

But it's a specific call in queries_note.rb,

explain = execute_without_analyzer("EXPLAIN #{query}", name)

Comment this line out, and all works fine.  However, I can't find where this
call, execute_without_analyzer,  is actually defined.  It seems like it
might be behaving differently between Rails 2.1 and 2.3

What's the best way to add observers from a plugin?
Replicating the behaviour of rails for adding a plugin or
http://github.com/zilkey/active_model_listener or is there another

 I suspect the reason you have not had a reply is that most people have
 not the foggiest idea what you are trying to do or what your question
 is.  That certainly applies to me.  Perhaps you could explain what you
 are trying to do, how you are trying to do it, and what is going
 wrong.

[Rails] error upgrading InstantRails on WinXP, 'could not find rails gem locally or in a repository'

[Brian]

I'm trying to upgrade to the latest version of rails.  I've been
happily using InstantRails2-0 for awhile and it's been great.
However, I've hit problems trying to upgrade.  I get the error in the
subject when I do 'gem install rails'.

I've read the Rails Wiki about upgrading rails and it doesn't have any
info on this error. The Rails Wiki said I needed to first do
update_rubygems, and it appears I was able to do that successfully. My
ruby version is 1.8.6. I googled this particular error and got a few
hits about making sure the gem sources included gems.rubyonrails.org,
which mine does.

I also found an article that suggested I download the latest rails
from github, which I also tried.

Turns out the gem update didn't work, after I checked my gem version
and found it was 1.2.  When I do 'gem install rubygems-update', I get
the same error:

'could not find gem rubygems-update locally or in a repository'

What am I doing wrong?

[Rails] named_scope with at least one association

[Jeff Blasius]

How would I write a named_scope that checks if the parent has at least
one associated child?

For example,
class Post < ActiveRecord::Base
  has many :comments

  named_scope :commented_on, :conditions => "comments.count > 0"


class Comment < ActiveRecord::Base
  belongs_to :post



Thanks,
jeff

Re: [Rails] Re: Cucumber + ajax + error

Ok I came to know where I was getting wrong.

   Then "a" invitation message should be sent to "ab...@example.com"

The "a" should be in capital. "A"

Then "A" invitation message should be sent to "ab...@example.com"

[Rails] Re: Submitting a form onDrop, parameters don't come through

[jhaagmans]

I may have been unclear about this: it does make a POST request to the
action URL, but the POST data is empty. This results, of course, in
the controller failing to process the data.

Re: [Rails] Re: Massive memory eating

[Peter De Berdt]

On 01 Dec 2009, at 13:45, Trausti Thor Johannsson wrote:

OK, let's go one step further then and boil it down to RMagick (and  
not ImageMagick): install the mini_magick gem and change the thumbnail  
processor to minimagick explicitly and look at memory consumption.  
Since Minimagick uses the command line to process images, you should  
see no significant memory usage increase in your Rails instance. Also  
keep an eye on the total memory usage on your server and whether the  
imagemagick process stays around after the file has been processed  
(mogrify), it shouldn't.

It consumes less memory if I don't create thumbnails.

[Rails] Submitting a form onDrop, parameters don't come through

[jhaagmans]

Hi,

I'm trying to submit a form onDrop using Scriptaculous. I have a small
form with a multi-select box. My form is just a standard HTML form,
but it doesn't have a submit button.


  ...
  select box
  ...


My droppable element is created like this:

<%= drop_receiving_element 'multi_drop_'+attribute.id.to_s, :accept =>
'group', :onDrop => "function(element) { $('multi_drop_form_#
{attribute.id.to_s}').request({parameters:{id:element}}); } " %>

As you can see, what I'm trying to do is submit a form and send the id
of the dragged element along with it as the id. But when I look in
Firebug, it doesn't POST at all! No id, but also no values from the
select box.

What am I doing wrong? Ondrop forms aren't really documented anywhere,
but I thought I figured it out!

Re: [Rails] Re: Massive memory eating

[Peter De Berdt]

Pfew, that's one Rails instance just eating more and more memory  
indeed. Have you been able to boil it down to RMagick itself.  
Otherwise I would suggest leaving thumbnailing out for a second and  
just saving the uploaded file to see if it is in fact the thumbnailing  
that eats your memory. We can work our way down from there.

Did you remember to run
rake rails:update
in your project directory?

To revert to 2.3.4 simply put
RAILS_GEM_VERSION = '2.3.4' unless defined? RAILS_GEM_VERSION
at the head of environment.rb (you should see a similar line there
already, probably commented out).

reverting is easy. just uninstall your current rails-gem. if didn't
uninstall 2.3.4 it should still be there and your done. if you
uninstalled it, just install it with -v=2.3.4.

[Rails] Re: ActionView::TemplateError (can't convert ActiveRecord::Error into String)

[icke]

Abhis,

Well figured.  I had in fact installed the plugin from
http://rubyforge.org/projects/custom-error-message/ which I think I
picked up from one of the Railscasts.  This project is now invalid so
I am guessing that this has now been killed and that
http://github.com/gumayunov/custom-err-msg/tree must be the "current
version".

I am not sure how you are meant to keep track of things like that
(Using GIT?) .  My app started off under an earlier version of Rails
and the plugin worked ok. It still does  until last week!

Abhis awarded a Gold Star and a House Point.

[Rails] Rails 2.3.5 - missing gem problem

[ct9a]

hi guys,

  I just updated to rails 2.3.5 on os X snow leopard.

When I try to run "rake routes", I get the following error indicating
that the searchlogic gem is not installed.



bash-3.2# gem install -v=2.3.5 rails

Successfully installed rails-2.3.5
1 gem installed
Installing ri documentation for rails-2.3.5...
Installing RDoc documentation for rails-2.3.5...
bash-3.2#
bash-3.2# rake routes
(in /Users/anexiole/projects/rails/RealAutoParts)
Missing these required gems:
  searchlogic

You're running:
  ruby 1.8.7.72 at /System/Library/Frameworks/Ruby.framework/Versions/
1.8/usr/bin/ruby
  rubygems 1.3.4 at /Users/anexiole/.gem/ruby/1.8, /Library/Ruby/Gems/
1.8, /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/
ruby/gems/1.8

Run `rake gems:install` to install the missing gems.





That cannot be right as it "rake routes" ran fine when I was still
using rails 2.3.4 and that I even ran "gem install searchlogic" (with
sudo) as per searchlogic's documentation.

Any ideas?

Also, does anyone know how to revert the rails version back to 2.3.4 ?
That could be a quick fix until people fix the any potential issue
with rails 2.3.5 .

thanks

What do your passenger-memory-stats show if I may ask (before and

Here is the command I used:

ruby script/plugin install git://github.com/aaronchi/jrails.git

I'm using windows XP to develop.

Thanks!

Re: [Rails] Re: Massive memory eating

[Trausti Thor Johannsson]

Hi Peter, here is my gemlist

actionmailer (2.3.5, 2.3.4, 2.3.3)
actionpack (2.3.5, 2.3.4, 2.3.3)
activerecord (2.3.5, 2.3.4, 2.3.3)
activeresource (2.3.5, 2.3.4, 2.3.3)
activesupport (2.3.5, 2.3.4, 2.3.3)
cgi_multipart_eof_fix (2.5.0)
daemons (1.0.10)
fastthread (1.0.7)
gem_plugin (0.2.3)
mongrel (1.1.5)
mysql (2.8.1)
passenger (2.2.7)
rack (1.0.1, 1.0.0)
rails (2.3.5, 2.3.3)
rake (0.8.7)
rmagick (2.12.1)
rubyzip (0.9.1)

and these are my plugins

attachment_fu (1-2 months old)
easy-fckeditor  0.8.1  (not used anywhere)
modporter-plugin (installed today)
will_paginate 2.3.6


Thats all, I just updated passenger to 2.2.7 but

just by uploading one picture, private memory grows from 10.5 MB to
81.5 (with picture size 1.5 MB) and with next picture 118 MB

I never ever use find(:all).  This is beyond ridiculous.  There has to
be something I am doing wrong.


Best regards,


Trausti

Hi, what's the exact command you're using to install the plugin?

[Rails] Rails 2.3.5 - Cannot install plugin

[hnghiem]

I'm always get the message "Plugin not found: ["git://github.com/
aaronchi/jrails.git"]" when trying to install a rails plugin, even for
SVN or GIT. After google search, some people suggest that replace
"git://" with "http://"; and add "/" at the end of the url. I tried and
it still does not work.

I used the ruby 1.9.1-p243 and rails 2.3.5. I run in verbose mode and
it show the message "#". Does it an issue of ruby 1.9.1 in rails 2.3.5? I do google
search a lot and still not know how to fix. Please help!

Thanks!

By the looks of it (every spawned Rails process takes about 40-ish  
MB), you're wildly spawning extra Rails processes for some reason. We  
are using attachment_fu (and paperclip for that matter) intensively in  
a number of our applications and have no problems with high memory  
usage (except the initial RMagick hit). There must be something either  
in your server processes (RMagick, ImageMagick, other gem, …) that's  
miscompiled or outdated or you have something around the image  
uploading that kills your server (threads spawning). The simple fact  
of the matter is that something is keeping the Passenger rails process  
busy and it spawns new ones to cope with new incoming requests.

Re: [Rails] Re: Massive memory eating

[Trausti Thor Johannsson]

Now I just installed mod_porter and all.  But when I use passenger-memory-stats

I can see that my app uses 194 MB memory, I upload 1 picture and bang
it uses 285 MB and 2nd picture it uses 316 MB.

This is just ridiculous for an app that only does one thing, upload
pictures and display thumbnails.

Any ideas ?
