[Rails] Re: rails on ruby-1.8.7

[MaD]

the current stable version (for 1.8) is 1.8.7. that's all you have to
know.

but to answer your question:
of course development is focussing on compatibility with the next
generation of ruby. 1.8.8 is still to come out later this year (even
though 1.9.1 has been released). but it's not experimental or
anything. 1.8.7 is working fine. with 1.9.1 there are still problems
with some gems.

[Rails] Re: fastercsv, freezing into vendor/gems

[MaD]

well, i just looked at it again. you're right: "rake gems:unpack"
should provide exactly the functionality you're looking for. however i
don't know why it's failing for you.

and on that snippet of yours: try it and tell us whether it's working
or not. looks promising.

[Rails] Re: rails on ruby-1.8.7

[toy]

Thanks for answering!
and please :), one more question.

I looked for '1.8.7' all the time.
I read '1.8.7' is as pre-release(or experimental-release) for '1.9'.

and I found this, in CHANGELOG of rails-2.1.2.
* Ruby 1.9 compatibility.  #1689, #10546 [Cheah Chu Yeow, frederico]

Is this the point of the answer?

Hi Paryank,

Though I have no direct solution for you, I think compile/install Ruby

[Rails] Re: Full Ajax Application

[Geekyra]

I'm not looking for full RIA as well, cos ur right Rails is the best
tool for back end and I really love the agile way. I'm just wan't to
make the client side run faster by partial refresh everything, why do
we need to refresh whole page if what we wan't to do is just refresh
one single line of data ? My point is I just want to make Net app run
faster for country who doesn't have a good net connection (for example
dial up 64kbps) who will suffer for waiting the whole page refreshing
when they only want to update 1 line data.

Actually i have done a full ajax app in rails but i think i violent
the rest way, for 7 rest route that rails provide I'm only using
create and update using form_remote_for and destroy using
link_to_remote. For new, edit, and show i'm using link_to_function
(not link_to_remote) so the client doesn't bother server at all, so
actually I doesn't have new, edit, and show method in controller,
aren't that breaking the REST way ?

And now i have some project that is a crazier ajax way :) I just have
one page (called it dashboard) that have 2 region left and right. On
the left I want to put it all the navigation and link to the data and
the right region is the view of data itself. So the point is everytime
i i choose the navigation on the left dashboard it will replace the
right dashboard with the data so I the view doesn't refesh full page
but only partial right region so It will run as fast as possible.
After several trying i realized the javascript code is really
complicated, so I just wan't to know are there any easier way to do my
problem ?

[Rails] Problem in integrating Juggernaut chat plugin with Community Engine

[saideep a.v.s]

Hello,

  I have been trying to integrate juggernaut chat plugin with
Community-engline and as rails decided to deprecate
add_variables_to_assigns method
in rails 2.2. They don't include this on the list of deprecated methods so I
don't know how to find an alternative to this method. This method is used by
the juggernaut plugin and I wanna try getting it to work with rails 2.2. I
tried copying the source code of this method and add_instance_variable_names
source to the application.rb file but now I'm getting NameError
(uninitialized class variable @@protected_view_variables in
ApplicationController). Does anyone know if there are any alternatives to
these methods?


Following is the error

NameError (undefined local variable or method `add_variables_to_assigns' for

[Rails] How to install Rails on CentOS 5.2

[Paryank]

Hi

I have installed CentOS 5.2 on my PC. Ruby 1.8.5 and Ruby-devel
packages are already installed. I have downloaded rubygems-1.3.1.tgz
package and installed it. Now I am trying to install Rails by the
command below:

gem install rails

But it gives me the following error:

ERROR:  While executing gem ... (Zlib::DataError)
incorrect header check

zlib and zlib-devel are already installed on my pc. I can install
other gems like hpricot etc. But still I cannot install rails.

Can somebody please guide me how can I install rails on CentOS?

Thank you,
Paryank

You're not doing ['approved = ?',false] for the sanitization as much  
as for letting the database adapter fill in its own notion of what  
value it uses for false.  Even if you were doing more than counting,  
you have control of the inputs so there's no SQL injection here.

I love Rails as well, and my post was not at all an attack on Rails. It 
just a matter of "the right tool for the right job." Rails is built to 
design a certain type of application and is best used for that task.

It just sounded to me like you were looking for a full-on RIA 
application, and there are some really great frameworks out there for 
building those. Most of them, however, don't really stand on their own. 
They need a back-end. They need something running on the server-side to 
take care of managing the application's data. Rails would make an 
excellent choice to act as that server-side piece. Besides that it's not 
likely that your entire web site will be built as an RIA. That may be 
just one small part of the larger site. Rails would also be an excellent 
choice for handling that which is outside the scope of the RIA.

What is constant about a variable that changes everytime the locale changes?
And if you have multiple users with different locales, potentially changes
with every request?  Given how changeable it is, why do you want to confuse
the future maintainer by implying it is constant when it isn't.

Or put another way, why can't the variable be named available_locales.

Shrug,

[Rails] Re: How to remove special characters? (ie. &)

Yachtman,

Check out http://www.ruby-doc.org/core-1.9/classes/CGI.html#M000527
(It worked with 2.2 also)

>> ugly = CGI::escapeHTML('')
=> "
"

>> print CGI::unescapeElement(ugly, "A", "IMG")

=> nil

>> print CGI::unescapeElement(ugly, "A", "IMG", "BR")
=> nil

There might be a higher level function too, but this shows you how you
might use this directly

perhaps creating the app with the version you need will help avoid

However, what I am testing is a library that actually modifies 
ActiveRecord behaviour based on the default_timezone setting. So, it is 
pointless to mock or stub what I am actually testing.  I eventually just 
overrode the environment setting in the test itself.

  it "should set the UTC time (for _at/_on) correctly" do
ActiveRecord::Base.default_timezone = "utc"
...

[Rails] Re: favored development environment

[blasterpal]

AgileHack,

I work in an in-house Rails shop for a fairly large site (we are a
team of about 7 developers, not including operations and QA).  We use
OSX on PowerMacs and Mac Minis with Textmate and git. Some are
starting to poke around with MacVim and others swear by Netbeans.
Secondly, everyone uses OSX for dev personally except for one guy who
uses Debian.

Largely, everyone chooses OSX and Macs, its not a forced decision. All
the vendors who come in to staff augment or work on other projects
from respectable Ruby/Rails shops always show up with Macbooks.

For what it's worth, I don't use a MacBook pro, never have. I think
they are too much $$ for RoR dev. I use a bottom of the line with
extra RAM.

Thanks for the info.  I neglected to mention that this is on Rails 1.2.6 
(please no one "helpfully suggest" that I upgrade - thanks ;]), so these 
options are not available.  It's fine - I won't die.

One further question, if you use a "unified" helper like date_select in 
the current v. of Rails (obviously), can you set different promopts for 
each component input field of the date?

adding a method to application.rb lets controllers call it because you  
are adding a method to ApplicationController and your controllers  
inherit from that.
In a test you are subclassing Test::Unit::TestCase (or more recently  
ActiveSupport::TestCase or some other class if you are using a  
different testing framework), so clearly you can't call and  
ApplicationController instance method. Easiest thing is probably to  
put the methods in a module and include it in both places.

Is the issue date a date column or a datetime column ?
if you have a datetime column containing  2009-02-09 14:00 and compare  
it to 2009-02-09 then the 2009-02-09 is turned into 2009-02-09 00:00  
which can mess things up for you.

I currently have a generator which creates a directory of files. I

I have always executed this generator via terminal and it always

[Rails] controller utility method: want to use in tests. Where should it go?

Hi,

I've a simple method I call in my action methods. So far I've put it
in application.rb in the ActionController class.

However I can't call it from my test code. Where should I be putting
it? I've tried adding this to application.rb :

module ActionController

  def handy
  return dostuff
  end

end

just remove that - it's an option only available with rails >= 2.1
(which was the case when you generated the app, but now you're trying
to run with an older version)

certainly don't skip to ruby 1.9 unless you are using a version of
rails ready for it (which right now means rails 2.3rc1).  I would
stick to 2.2.2 if you're still learning

[Rails] Re: AR:BASE.default_timezone

[Foliosus]

in your test_helper:

require 'mocha'

Then, in your test

def test_something
  tz = :local
  ActiveRecord::Base.expects(:default_timezone).returns(tz)
  assert_equal tz, ActiveRecord::Base.default_timezone
end

The trick is to set tz to be whatever you want to get back from
AR::Base.default_timezone.  If you use AR::Base.expects, then your
test will fail if AR::Base.default_timezone is called more than once
or not at all.  If you don't care how many times it gets called (i.e.,
if that's not something you need to test), then use "AR::Base.stubs
(:default_timezone).returns(tz)" instead.

[Rails] Newbie - has_many :through case?

[gamericax]

hi,

i'm a newbie digging ROR for a week (and loving it i might add) and
trying to get a project done at the same time.  i'm more used to
direct SQL so trying to get hang of active record asssociations and
figure out what is done for me and what is not by script/generate
model and db:migrate.

in a nutshell, i have 3 core models where users enter competitions
with submissions.

entities:
- competition
- user
- submission

will need to:
pull all submissions by competition
pull all users by competition
pull all competitions by user
pull all submissions by user


1. is this a case of has_many :through like so?

class Competition < ActiveRecord::Base
  has_many :submissions
  has_many :users, :through => :submission
end

class Submission < ActiveRecord::Base
  belongs_to :competition
  belongs_to :submission
end

class User < ActiveRecord::Base
  has_many :submissions
  has_many :competitions, :through => :submissions
end


2. do i create joining tables and define FKs by updating migration
script manually?  if there are materials on step instructions you can
point me to, that will be great too!

3. if i need to add polymorphic behaviors(e.g. commentable and
rateable) to each of these models, do i just pile up the association
definitions?  after adding on media and various type/category models,
this probably will get pretty long and not sure whether cache/memory/
performance situation will become unmanageable.  An example of
relatively complex association definition will give me a good idea.

thx for reading.

[Rails] acts_as_textiled missing something, possibly config?

[mfabache]

I've got acts_as_textiled working on my Mac,no problems.
Same install process on RedHat FC8, is acting weird.

For example:

1.) Already inplace HTML tags are not translated.  An  appears as
.  However any new 'h1.' works fine
2.) putting in href substitues get blownout into some weird
representation.  a "Listings" which I want to get
translated as "Listings":/lists actually gets translated to
"
"Listings":/lists

Have I missed something, somewheres?
RedCloth is 3.0.4 and 4.1.1, acts_as_textiled I got from github (git
clone...)

I've also tried various browsers (lynx, opera, firefox, etc.), same
result.

[Rails] Fixtures load inconsistently

[Foliosus]

Hi all,

I've got a weird problem with loading fixtures, and I'm hoping someone
out there can help.  I'm having problems running my tests, because for
one of my models the fixtures are loading strangely.  Here's an
example fixture:

john_doe:
  status: student
  department:
  alumni:
  title:
  applicant:
  student_status:
  staff:
  pref_first_name:
  faculty:
  applicant_status:
  year_in_school: freshman
  chair:
  pidm: 12345678
  reed_id: L12345
  program:
  middle_initial:
  first_name: John
  student: Y
  login: doej
  last_name: Doe
  email: d...@reed.edu

This is a model that's wrapping a legacy table.  It has no id column.
However, its pidm column is the primary key, so in my model I've got:

  set_primary_key :pidm
  alias_attribute :id, :pidm

If I load up my fixtures using "rake:fixtures:load RAILS_ENV=test"
then everything works just fine.  My 5 fixtures for this model go in
to the test db exactly as written.  However, when I run my test suite,
and rails loads the fixtures, 3 of the 5 fixtures load up with their
pidm field set to 91.

It's surprising because it's only 3 of the 5. I've been poking at it
all morning, with no luck. I've changed data values, etc., and it's
always the same 3 that come out with 91.  The other 2 fixtures have
the pidm that's set in the fixture's yaml file.

Has anybody encountered this? Or does anybody have suggestions?

Thanks!

[Rails] Help with Scaffolding deprecation on Rails 2.2.2

[untz]

I am reading “Agile Web Development with Rails, 2nd Edition”, which is
based on 1.2.6. However, on my Leopard based iMac, I was running Rails
2.2.2.

When I got to the part with associating a scaffold to my :products
(located on the bottom of page 67), it outputted a No Scaffold method
error (because scaffolds are not included in 2.2.2).

After searching some web sites, particularly , I tried to install 1.2.6 by issuing: gem
install rails—version 1.2.6—include-dependencies.

This worked correctly, but when I still type check the current version
from bash it states:

Rails 2.2.2

I then went into my app’s config/environment.rb file and set
RAILS_GEM_VERSION to 1.2.6.

When I tried to re-start the WEBrick server, I got the following
error:

=> Booting WEBrick…
./script/../config/../config/environment.rb:46: undefined method
`time_zone=’ for # (NoMethodError)
from /Users/untz/.gem/ruby/1.8/gems/rails-1.2.6/lib/initializer.rb:
45:in `run’ from ./script/../config/../config/environment.rb:13

On line 46, on my WEBrick server, this is what is set:

config.time_zone = ‘UTC’

Question(s):

(1) Should I stick with learning Rails 2.2.2 and upgrade to Ruby 1.9?

(2) Is the 2nd Edition of this book now deprecated or is there a
workaround to my problem?

(3) Any good resources on learning the new version of Rails?

Happy programming!

[Rails] Re: can't call request.remote_ip from object?

[Foliosus]

Models should be blissfully unaware that they are attached to a web
app.  For example, if you use your models from the console, or a rake
task, there is no web app, so if your models assume that a controller
exists you're asking for trouble.

In this case, however, you can simply feed the :last_known_up
and :last_known_user_agent to your model this way:

class UserController
  def some_action
@user = User.find(params[:id])
@user.update_metadata(:last_known_up =>
request.remote_ip, :last_known_user_agent => request.user_agent)
  end
end

class User
  def update_metadata(options = {})
options.reverse_merge!(:last_login_at => Time.now)
self.update_attributes(options)
  end
end

If the :include_blank option is a string then that is used for the
blank option. There's also the :prompt option. I do recall that
support of this with the date_select stuff was only added recently.

I've tried that; there are lots of things out there that assume the

Even if I remove it, though, I still get the same weird loading

I'm not sure if it changes your situation, but you shouldn't need that  
alias_attribute.  Just use id and ActiveRecord should use your real  
primary key column under the covers.

[Rails] threading, returning from action method, blocking

[Jonathan Rochkind]

So, in a Rails 2.1 app, I'm doing a bit of threading. Even though this
isn't exactly recommended, it seemed to work (taking care to use
ActiveRecord in a thread-safe manner, or not at all in threads).

But I've noticed something odd.

The main thing I do with a thread, is in an action method (ie, an action
in a controller), right before returning from the method, I start a
thread to do some finishing up clean-up in the background. Since this
cleanup is potentially a lengthy process, the idea is that this won't
prevent the response from returning to the browser.

def someAction
  # some stuff

  Thread.new do
#background(?) stuff
  end

  return
end

The expectation was that the response would be returned to the browser
immediately, it would not wait for that Thread to execute. It wouldn't
matter how long the code in "#background(?) stuff" took to run, the
Thread would be started, and then the next statement would be read after
the thread, ending the action method, proceeding with the view, without
waiting on the Thread. Everything could be asynchronous.

However, I've recently noticed that this doesn't seem to be the case.
The stuff in the Thread _is_ keeping the response from being returned.
If I put a "sleep(10)" at the top of the Thread do body, then everything
clears up--it doesn't wait an extra 10 seconds for teh response, THEN
the response is returned immediately. But without this, it seems that
something in the Thread is blocking the rest of the Rails process to
return the response, not for the entire time it takes it to run, but...
for some time.

Does anyone have any ideas what's going on, or how else to accomplish
this? (Please don't same BackgrounDRB).

Thanks,

Jonathan

[Rails] Re: Help with routes and params

[Freddy Andersen]

I think you have to have a look at Rails basics. A basic forum would
be something like:

forums has_many categories
categories has_many topics
topics has_many replies

then you have has_many routes like /forums/1/categories/1/topic and in
your routes.rb you would do

map.resources :forums do |forum|
  forum.resources :categories do |cat|
cat.resources :topics
  end
end

You could add :has_many => :topics but if you need members and/or
collections later its better this way.

[Rails] Pretty Record Lists

[Chad]

Can anyone recommend a lightweight plugin that renders lists of
records nicely with ajax sort, pagination, edit/delete links, etc?  I
tried ActiveScaffold, which is really great, but it's too much for
what I'm trying to accomplish.

Ideally it would be used sorta like this (similar to AS):

controller:
@users = company.users

view:
<%= render :pretty_lists => @users %>

Thanks for any help,
Chad

[Rails] Re: Option on select form helper to customize "Select" text?

[Rick]

Try this:

script/generate scaffold Thing name:string when:datetime text:body

You'll see:

In migration:

create_table :things do |t|
  t.string :name
  t.datetime :when
  t.text :body
end

In view:

New thing

<% form_for(@thing) do |f| %>
  <%= f.error_messages %>
.
.
  
<%= f.label :when %>
<%= f.datetime_select :when %>

[Rails] Re: mysql install problem

[Brent Miller]

If you're on an Intel mac, try this:

sudo env ARCHFLAGS="-arch i386" gem install mysql -- 
--with-mysql-dir=/usr/local/mysql
sudo ln -s /usr/local/mysql/lib /usr/local/mysql/lib/mysql

Just be sure to get the mysql directories right to match your system 
setup.  These are the default for the MySQL binaries.

[Rails] dynamic constant assignment

[Erwin]

I have a constant set up like that :
ALL_LOCALES

GB"=>"English (UK)", "es"=>"Español (España)", "pt-PT"=>"Português",
"pl"=>"Polski", "en-US"=>"English (US)", "pt-BR"=>"Português
(Brasil)"}

my locale is set :  I18n.locale
=> :"en-US"

based on the current locale , dynamically changed, I would like to
define a new constant,   AVAILABLE_LOCALES which would be the
ALL_LOCALES minus the current locale...

AVAILABLE_LOCALES
=> {"it"=>"Italian", "fr"=>"Français", "de"=>"Deutsch", "en-
GB"=>"English (UK)", "es"=>"Español (España)", "pt-PT"=>"Português",
"pl"=>"Polski", "pt-BR"=>"Português (Brasil)"}

[Rails] Re: can't call request.remote_ip from object?

[Brent Miller]

Here's the sort of thing you're looking for:

class UserController
  def some_action
@user = User.find(params[:id])
@user.update_metadata(:last_known_ip => request.remote_ip,
  :last_known_user_agent => request.user_agent)
  end
end

class User
  def update_metadata(options = {})
options.reverse_merge!(:last_login_at => Time.now)
self.update_attributes(options)
  end
end

This will update the request data only if you're coming from a 
controller, where there is request data.

[Rails] dbd-odbc gem not

[Ben Lieber]

I have an application that requires dbd-odbc gem in order to work. So I
have to following in the environment.rb:

---
config.gem 'dbd-odbc', :version => '0.2.4', :lib => 'dbd/ODBC'
---

I recently had to switch to a new computer, so new install of ubuntu,
rails, gems, etc. I installed dbd-odbc as you can see:

---
$ gem list
...
dbd-odbc (0.2.4)
...
---

my app keeps failing though, and if I run a rake, it tries to reinstall
the same gem each time, but then the app still doesn't see it:

---
$ sudo rake gems:install
[trace ...]
no such file to load -- dbd-odbc
[trace ...]
gem install dbd-odbc --version "= 0.2.4"
Successfully installed dbd-odbc-0.2.4
1 gem installed
Installing ri documentation for dbd-odbc-0.2.4...
Installing RDoc documentation for dbd-odbc-0.2.4...

Has anyone seen this behavior before?

Thanks for any help!

[Rails] Re: AR:BASE.default_timezone

[Brent Miller]

What you really want to do is mock the default_timezone for the scope of 
a particular test.  For example,

require 'mocha'

class MagikTest < ActiveSupport::TestCase
  def test_something
tz = 'Alaska'
ActiveRecord::Base.stubs(:default_timezone).returns(tz)
assert_equal tz, ActiveRecord::Base.default_timezone
  end
end

This just shows you how the stubbing works; in practice, this test is 
testing the Mocha library, and not your app. :)  The trick here is to 
decide what you want the default_timezone call to return, and assign 
that value to tz.  Then every time you call AR::Base.default_timezone 
during that test, you'll get back the value of tz.

You'll need to grab the mocha library first: gem install mocha

You can use this to test your app against multiple timezones to really 
make sure it works.

[Rails] Fixtures loading *very* strangely

[Brent Miller]

Hi all,

I've just hit a snag, and I'm hoping somebody out there can help.

I'm working on an app that uses some legacy tables.  One of them doesn't
have a column named "id" so I've got the following:

class Student
  set_primary_key 'pidm'
  alias_attribute :id, :pidm
end

When I'm testing, I need 5 student fixtures.  I have them defined like
this one:

john_doe:
  status: student
  department:
  alumni:
  title:
  applicant:
  student_status:
  staff:
  pref_first_name:
  faculty:
  applicant_status:
  year_in_school: freshman
  chair:
  pidm: 12345678
  reed_id: L12345
  program:
  middle_initial:
  first_name: John
  student: Y
  login: doej
  last_name: Doe
  email: d...@reed.edu

When I load the fixtures into my test database with "rake
db:fixtures:load RAILS_ENV=test" everything works great.  However, when
I run my test suite, and rails loads the fixtures, I get a big problem:
three of the fixtures aren't loading with their pidm (id) correctly.
All three load with a pidm of 91, which is problematic since it breaks
any associations involving that primary key.

The two other fixtures load ok, though, which makes me very confused.

I've played around with the data differences between the fixtures, and
futzing the non-pidm data doesn't seem to do anything.

Has anybody encountered this?  Any advice?

Thanks!

[Rails] Re: Problems with SQL Server 2008 and migrations using activerecord-odbc-adapter gem

Huh, good post, I was having the same issue approx the same time 
(http://www.ruby-forum.com/topic/176528#773255), wish I had found your 
post then.

I'm on a SqlServer 2005 db, but it was the same exact issue. Ended up 
switching to the rails-sqlserver-2000-2005-adapter and most problems 
went away. But good to know the actual cause of the original issue.

Thanks!

[Rails] Re: Help with routes and params

[John Yerhot]

Hi John,

I highly suggest you take a peek as the associations that Rails
provides.  A good place to start is the Rails Guides.
http://guides.rubyonrails.org/association_basics.html
and also the guide on routes (particularly the part on nested
resources)
http://guides.rubyonrails.org/routing_outside_in.html
These will make life much easier for you if you follow them.

Sorry for not really answering your question... :)


Again, I would go this route though.  :)

[Rails] Re: Run rake tasks from the controller

[K. R.]

But why do you not use the 'ftools' of ruby? so you can forgot the rake 
task.

Create a folder:
FileUtils.mkdir_p 'name'

Destroy a folder:
FileUtils.rm_rf(path)


With after_save you can call the method who use .mkdir and with 
after_destroy .rm_rf...

for example:
after_save :create_folder
after_destroy :destroy_folder

private
def create_folder
  FileUtils.mkdir_p 'name'
end

def destroy_folder
  FileUtils.rm_rf(path)
end

to create a directory (folder) for a particular user when he/she
creates an account in my website. That will be the folder were all the
things he/she uploads will be stored. So I want to run a rake task
that will create the user folder once he registers. So the idea is to
have a rake task on an observer and pass the user business name that
will be used to name the folder.

I hope I explained myself.

Thanks

[Rails] Re: can't call request.remote_ip from object?

[K. R.]

request are only readable in the controller. Take the ip address in the 
controller and move it as a parameter into the model.

ip = request.remote_ip
@model.ip = ip

or put it into a hash (with all other parameters) and call the method in 
the model.

[Rails] Re: Run rake tasks from the controller

[K. R.]

Why do you run rake tasks in the controller? controllers are not really 
good to execute rake tasks. move it into the model and call it from the 
controller.

[Rails] Image rotator plugin

[Shockmeister]

Hi all,

Has anyone used farooq ali's rails plugin for media applications? (see
link below)

http://www.jroller.com/abstractScope/entry/flash_mp3_imageslideshow_media_player

I am trying to create a simple slideshow on my site and I am using
farooq's plugin for image rotator (http://www.longtailvideo.com/). I
have created an xspf playlist file to run through the images. When I
open the browser, however, the images are not displaying. I have never
written an xspf file before so I'm not sure what I'm doing wrong. Can
someone take a look at my xspf file to see if is correct? At least
then I'll know that the problem lies elsewhere.


http://xspf.org/ns/0/";>

[Rails] Specifying session_id in params?

[Brian Culler]

I am using a Flex based front end on top of a rails backend.  When the
SWF is first loaded from the rails app to the client's browser, a
session is created on the rails side.

However, subsequent requests from the loaded Flex app are also creating
whole new sessions as well.  I need the flex app's calls to continue
using the existing session.

So I am sending the flexapp the original session id, and am then
appending that session id into the params when it sends it back.  Is
there anything else you need to do besides inserting the specific
session id into the request params to get rails to use that session id
instead of making a new one?  If it makes a difference, this is a
multipart post from the flex app back to the rails server.

Here is an example sequence of events -- the first request is what
serves the SWF to the client's browser:

Processing MainController#index (for 127.0.0.1 at 2009-02-09 15:31:44)
[GET]
  Session ID: ff99a1a31c21bcd247390e8c54b65dc9

Next, I am doing a callback from within the flex SWF as a multipart post
request, with the "_session_id" parameter specified:

Processing ApiController#upload (for 127.0.0.1 at 2009-02-09 15:32:05)
[POST]
  Session ID: c104c28b75d712f3dd81f59dd39d963d
  Parameters: {"Filename"=>"att2.jpg",
"_session_id"=>"ff99a1a31c21bcd247390e8c54b65dc9", "action"=>"upload",
"Upload"=>"Submit Query", "controller"=>"api", "fb_sig_user"=>"null",
"Filedata"=>#}

As you can see, the "_session_id" parameter in the 2nd request matches
the first requests Session ID.  However, the 2nd request clearly is
getting a different session.

Any ideas?

[Rails] flickraw: flickr.tags.getListUserRaw

[ha we]

Hi!

I need to call the flickr.tags.getListUserRaw API method
(http://www.flickr.com/services/api/flickr.tags.getListUserRaw.html)
with the flickraw gem.

Unfortunately there is no documentation how to authenticate and then
call the method. Just calling flickr.tags.getListUserRaw doesn't work,
although flickr.tags.getListUser does work.

I set my FlickRaw.api_key and FlickRaw.shared_secret ... how do I go
about now?

Thanks.

[Rails] ferret - mysql server has gone away

[K. R.]

I've problem with ferret (acts_as_ferret). search-engine and webserver
are on the same machine. I use acts_as_ferret :field => ... to define
which columns are indexed. I recreate the index with
Search.rebuild_index (Search is my model).

To find some results, I use Search.find_with_ferret("keyword", {}, {}).
Sometimes, I merge conditions to this query in the last hash. I create
an index over 7'000 records.

For a while, the search is run correctly. Suddently, after perhaps 10
requests, I receive the error message below and the search doesn't run
anymore.

Has someone a solution for this problem Thanks for helping!

[Rails] Option on select form helper to customize "Select" text?

[Wes Gamble]

All,

Is there any built-in way in the "select" form helper to display
something other than "Select" in the :include_blank option?
Specifically, for a date helper, would like to show "Month", "Day",
"Year" respectively for those options in 3 selects.

Thanks,
Wes

[Rails] [ANN] The end of Capchas: Thorny Form plugin

[Wybo Wiersma]

Thorny Form is a Rails plugin for unobtrusively protecting forms
against form-SPAM.

It adds extra fields like a honeypot and some others which can then be
checked before the form-data is used in your application. 

To use Thorny Form you just need to change two lines per form. First
in the view 
  form_for has to be replaced by thorny_form_for
  (remote_form_for by remote_thorny_form_for). 
  
Then in the controller you have to add a check for spam in the shape 
of
  self.thorny_form_free_of_spam?. 
  
See the full Thorny Form docs for a code example and installation 
instructions here:
http://www.logilogi.org/pub/doc/plugins/thorny_form/

It is not an unbreakable solution, but it is likely to continue to
work for quite some time. The following joke from Ned Batchelders blog
nicely sketches why:

Jim and Joe are out hiking in the forest, when in the distance,
they see a huge bear. The bear notices them, and begins angrily
running toward them. Jim calmly checks the knots of his shoes and
stretches his legs.

Joe asks incredulously, “What are you doing? Do you think you can
outrun that bear!?”

Jim replies, “I don’t have to outrun the bear, I just have to
outrun you.”

Thorny Form is under the Affero GPL, and developed by the LogiLogi
Foundation (http://foundation.logilogi.org)

[Rails] can't call request.remote_ip from object?

[Taylor Strait]

class User

  def update_metadata
self.update_attributes({:last_login_at => Time.now,
:last_known_up => request.remote_ip,
:last_known_user_agent =>
request.user_agent})
  end

This does not work. It bombs out with:

undefined local variable or method `request' for #

But the request calls work in a controller such as:

@ip = request.remote_ip
@agent = request.user_agent

What is the proper way to get this data into my model?

[Rails] classpath Issue

[Ganesh Krishnan]

I am new to Ruby/RoR and would appreciate any help on the issue I am
trying to resolve far past 2 days.

I have a java application as a jar and I have included in the controller
as below.

  require 'java'
  require 'C:/Documents and Settings/user/Desktop/application.jar'

  include_package 'whatever.something'

After that I am calling a method from one of the classes in the jar.

  puts Java::WhateverSomething::Engine.helloWorld()

This helloWorld() program does a very complex thing :) and returns an id
string that I am trying to display in the console. This external
application has a call to the DB.

I have the driver jar in the application.jar. Also, I have included in
the RoR java runtime library and all places I can think of but still I
am getting the 'Class Not Found' exception. Can someone point what I am
doing wrong?

java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
...
java.sql.SQLException: No suitable driver
at java.sql.DriverManager.getConnection(DriverManager.java:545)
at java.sql.DriverManager.getConnection(DriverManager.java:171)
...

Thanks.

[Rails] Re: development Windows or Linux?

[EduardoChinchilla]

My 2 cents:

I never used Linux before, the first task I did after installing
Ubuntu, a month ago,  was to set up a Rails environment, if you´re
from Windows world it could take some time just because it´s different
to install software in Linux, but once all it´s set up you don´t have
to mess a lot with the OS. There are many good tutorials on the web.
Now i´m the happy owner of a linux box with a complete Rails
environment for free, if it helps I could tell you that I only had  2
problems:

1. Using Netbeans 6.5 for linux I had problems to configure it to use
my gems repository for the ruby interpreter (not JRuby), this is when
I realize that in Ubuntu I was not the root user! and NB require real
root user permissions. I tried to configure GEM_PATH to use a
repository inside my user dir but this did not work. After some hours
of battle I give up and tried Netbeans 7, and it works!! Of course if
you don´t plan to use Netbeans you do not have to care.

2.I recommend to install Git before you start any programming, sooner
or later you´ll need it. for example:
   script/plugin install git://github.com/thoughtbot/paperclip.git won
´t work if you do not have Git installed on your system,who knows
it!!!. Well this may not be a linux issue but if you are as clueless
as me this could save you some time

In the end it is a good learning experience, and I do not regret of my
decision.

Good luck

[Rails] AR:BASE.default_timezone

[James Byrne]

I have a requirement to test code whose execution depends upon the
default_timezone setting.  I have tried several approaches to this but
nothing that I do in my test seems to alter the behaviour that is set in
environment.rb.

Is there a way to dynamically alter AR's method of storing datetime
during a test? Currently I attempt to do this in this fashion:

[ "local", "utc" ].each do |tz|
  ActiveRecord::Base.default_timezone = tz
  @my_mage = Magik.new
  @my_mage.description = tz
  @my_mage.my_time_local = DateTime.now
  @my_mage.my_time_utc = DateTime.now.utc
  @my_mage.save!
  puts @my_mage.description
end

but the contents of the my_time_local and my_time_utc do not seem to be
what I expect:

default_timezone = local
Local: Mon Feb 09 14:20:06 UTC 2009 = 1234189206.0 <- AR.my_time_local
  now: Mon Feb 09 14:20:06 -0500 2009 = 1234207206.77585 <- Time.now
  UTC: Mon Feb 09 19:20:06 UTC 2009 = 1234207206.0 <- AR.my_time.utc
  now: Mon Feb 09 19:20:06 UTC 2009 = 1234207206.77609 <- Time.now.utc

default_timezone = utc
Local: Mon Feb 09 14:20:06 UTC 2009 = 1234189206.0 <- AR.my_time_local
  now: Mon Feb 09 14:20:06 -0500 2009 = 1234207206.77807 <- Time.now
  UTC: Mon Feb 09 19:20:06 UTC 2009 = 1234207206.0 <- AR.my_time.utc
  now: Mon Feb 09 19:20:06 UTC 2009 = 1234207206.7783 <- Time.now.utc
.

Is it possible to override AR default_timezone values for testing?

Thanks for your reply, and your help! It gave me a hint and solved the 
problem like this:

 self.cond << ["invoices.issue_date > ?", from - 1] unless from.blank?
 self.cond << ["invoices.issue_date < ?", to + 1] unless to.blank?

because issue_date is a datetime, and generating an invoice means saving 
both date and time of the day. This way the search will have the same 
results as in your example.

Once again, thank you for your help!

[Rails] rendering original view

[bingo bob]

  def create

# next statement is original and is removed
# @review = Review.new(params[:review])

@school = School.find(params[:school_id])
# @review = @school.reviews.create!(params[:review])
@review = @school.reviews.build(params[:review])


respond_to do |format|
  if @review.save

flash[:notice] = 'Review was successfully created.'
# format.html { redirect_to(@review) }
format.html { redirect_to(@school) }
format.xml  { render :xml => @review, :status => :created,
:location => @review }
  else
# format.html { render :action => "new" }
format.html { render :action => "new" }  #  <- HERE
format.xml  { render :xml => @review.errors, :status =>
:unprocessable_entity }
  end
end
  end


In this view the line

format.html { render :action => "new" }

renders the reviews new method when the validation fails...thing is I
want to show the school and the error messages, (schools controller show
method) like this line,  format.html { redirect_to(@school) }.

any help on how to do this?

[Rails] submit_to_remote change from 2.1 to 2.2 now gives wrong number of arguments

[Andres Paglayan]

Hi,

this snippet

<%= submit_to_remote('create_button', 'Add Phone',
  :submit =>
"phone_form",
:url =>
send( "#...@phonable_type.to_s.downcase.singularize}_phones_path",
@phonable_id),
:method => "post",
   :html => {:class =>
'submit'}
 ) %>


was working totally fine under 2.1.1,
it throws wrong number of arguments (3 for 2) on 2.2.2

submit_to_remote on 2.1.1
was

# File
vendor/rails/actionpack/lib/action_view/helpers/prototype_helper.rb,
line 412 

412:   def submit_to_remote(name, value, options = {})
413: options[:with] ||= 'Form.serialize(this.form)'
414: 
415: options[:html] ||= {}
416: options[:html][:type] = 'button'
417: options[:html][:onclick] = "#{remote_function(options)}; return 
false;"
418: options[:html][:name] = name
419: options[:html][:value] = value
420: 
421: tag("input", options[:html], false)
422:   end


while on 2.2.2 is

# File vendor/rails/actionpack/lib/action_view/helpers/prototype_helper.rb, 
line 421
421:   def submit_to_remote(name, value, options = {})
422: options[:with] ||= 'Form.serialize(this.form)'
423: 
424: html_options = options.delete(:html) || {}
425: html_options[:name] = name
426: 
427: button_to_remote(value, options, html_options)
428:   end


now it wraps the lower level button_to_remote,
but I don't get why mine is failing,


looks like submit and button to remote should be the same,
but not sure what's going on,

any help is appreciated,

Thank you,

[Rails] Help with routes and params

[John Smith]

I need some help with routes and params. I am developming some forums
for a web. I want to be able to create new replies once a post has been
created. So I create a post and then I have to put a link named "Reply".
What I want to do is Reply.create, and pass post_id as a param to this
Reply.create action. How can I make this link? How can I get this param
in replies controller?
I  think I can create a whole new action, but I would like to use
Reply.create.
