If you want to use mysql, then set up your rails project like this:
% rails --database=mysql 
If you leave out the database option, rails will assume you want
sqlite3.
(I think mysql used to be the default some time ago).

You can alter the database and connection settings in config/
database.yaml.

[Rails] Problem creating Hello World app in Ruby on Rails

[David Park]

Hi All,

I just installed Ruby on Rails on my MacBook Pro and tried to create the
Hello World app that is documented in the Agile Development with Rails
book.  I followed all the instructions for creating the Hello World app
but get the following error when I try to load
http://localhost:3000/say/hello

MissingSourceFile in SayController#index

no such file to load -- sqlite3


Can anyone please let me know what I need to do to fix this issue?
Thanks!

P.S., I have the following things installed on my MacBook Pro:

1. Ruby 1.8.6
2. Rails 2.1.2
3. MySQL 5.0.67

[Rails] SOAP::MAPPING::OBJECT

[Pallavi Gawas]

Hi,

 I have written a SOAP4R client and have called a method on the Server.
This method return me a SOAP::MAPPING::OBJECT. My problem is that I dont
know how to access the contents of this SOAP::MAPPING::OBJECT. The
method inspect displays the data but its displays it as a string. I want
to access and display individual elements so the method inspect is of no
use to me. Any help will be appreciated.

Thanks and Regards,
Pallavi

[Rails] Re: Problem starting WEBrick

[Rick]

Since rails comes in as a gem, it's doubtful that you don't have
rubygems installed.  It is possible that you have ruby and gems
installed in non-standard locations.

On my mac:

which ruby => /opt/local/bin/ruby
which gem => /opt/local/bin/gem
which rails => /opt/local/bin/rails

ruby --version => ruby 1.8.7 (2008-08-11 patchlevel 72) [powerpc-
darwin9]
gem --version => 1.3.0
rails --version => Rails 2.2.0

NOTE: This is not what ships on the mac - that's all found below:

/System/Library/Frameworks/Ruby.framework/...

You would probably do best if you go to: http://www.rubyonrails.org/down
and follow the directions there.

[Rails] Re: pagination in ajax

[Sijo Kg]

Hi
If u use gem install to install will_paginate the library files you 
can find inside /usr/lib/ruby/gems/#versionNo/gems/ (For linux) for 
windows you have to find out where the location..I think in 
ProgramFiles(right?)
 You can find all the installed gems there .And go to will_paginate 
directory there Inside that go to lib directory .There you can find out 
the required file..

[Rails] Re: Backwards N+1 problem

[Richard Schneeman]

That knocked off about 1000ms, thanks for the help! Is it possible to 
re-arrange the order of your database all together??

When I take out the :order => 'rank desc' my sql call time gets cut in 
half, is there any way to tell RoR to automatically sort my definitions 
(in the DB) by  rank descending??

I already have this code in my phrase.rb

"has_many :definitions, :order => 'rank DESC'"

but is it possible to have an entire model be automatically ordered by a 
specific column inside of the database?? In this case by rank.

[Rails] Re: backgroundrb misbehaving again

[Bharat Ruparel]

Please disregard.
For those who might be interested, the problem was that Backgroundrb had 
spawned a rogue linux process on the port that backgroundrb was supposed 
to listen on and will not go down when you shut Backgroundrb via normal 
commands.  I had to find it and then do a kill -9.
After that, it worked fine.
Are there any simpler to debug and more reliable alternatives out there? 
I mainly need a cron style functionality to send out scheduled reminders 
and download feeds  which are also scheduled.
Thanks.
Bharat

[Rails] Re: Acts as tree and belongs to

[boblu]

I think you' better write a method rather than using belongs_to.
In my opnion, if you use belongs_to :xxx, than you get xxx for all the
object of Category class, not just the root category.
If you write a seperate method, you can write your own logic in it,
for example, for every category, you first find its root category, and
then return the section object of that root category.
And I think you can just use that as the same as by using belongs_to

I don't know if I could recommend a license... I'm not a lawyer and
all that.  I will say that I don't believe there exists an OSS license
which would prevent someone from starting a competitive site using
your code.  The only all the open source licenses I'm aware of would
control is under what circumstances would they have to release their
code changes back to you & the world.

I can say this from personal experience:

Making code open source (regardless of the license) doesn't magically
cause people to contribute to your project. That takes a community of
individuals who want to solve a shared problem.

IMHO, if you're looking for people to help you with the project, then
your best bet is probably to seek out qualified developers (or people
interested in learning) within your existing user base who already
find it useful and would like to give back.

There are only two reasons I can think of that someone would download
your code and do anything with it:
1) They want to help you out
2) They want to start their own site using your code

You could easily have people email you to get access to the code for
#1 and filter out people interested in #2 all without releasing the
code under the GPL, etc.

I will say this though.  Either GPL your code or have people assign
their copyright to you.  I was involved in a web project where the
main developer kept the copyright and didn't assign a license which
allowed it to be redistributed other then the server.  Then when the
developer decided she didn't want to work on the site anymore she
wouldn't allow us to give it to other developers- which basically
meant we had to start over from scratch.

Good luck,
Aaron

[Rails] Re: TeachMate.org goes opensource

[torm3nt]

I guess that's the fear with making any project opensource -
competitors. But also bear in mind that that's one of the things that
makes opensource so powerful, it's how we grow as a massive global
community, living and learning from our mistakes and building off
others' mistakes as well.

Think of it as giving back to a community that has given you so
much :)

Before publishing I talked to some guys and they said publish it under
GPL. I looked through the license and it seemed good enough for it.
Personally, I give a damn about licenses and stuff, they really make

Have you checked what is consuming the memory?
The environment should take about 60mb (not 100% about that).
>From my experience most memory consuming operations are related with
creating objects from find(:all, ) queries.
Can you change the ActiveRecord find into raw sql queries and compare
results?
I remember case with my code - memory usage jumped from 600mb do 180mb
after changing find(:all, ...) into sql.

The other thing is the script/runner - I don't know if it will make
any difference but you could try with rake task's instead of script/
runner.

[Rails] Acts as tree and belongs to

[Panda Beer]

Hello all,
is that possible to define an association between Section and Category
just for the root of a category?

Here is my Category model:

class Category < ActiveRecord::Base
  acts_as_tree :order => "name"
  belongs_to :sections # just for the root of Category
end

Thank you.

Will all the pictures on the site be localized?
Probably not - maybe it would be better if you create a method called
something like

image_localized_tag

in your application helper. It could take "locale" from cookie and
change passed file name (locale isn't parameter now).
After changing the name it could just call image_tag and return the
result.

This is just a suggestion - IMHO it's easier to implement and cleaner
later on for other developers - some of them may expect different
behaviour from image_tag

[Rails] Script/Runner

[Oliver Nightingale]

I have a production site that has a couple of batch jobs, I have used
script/runner and cron to run these jobs.  This works ok for jobs that
only run once overnight during off peak.

I am expiring sessions older than 30 mins every 15 mins using
script/runner, but I'm concerned about the hit of script/runner loading
up the whole rails environment, specifically since I only have a 256MB
slice, at such regular intervals.

What is a more efficient way of clearing down these sessions (using AR
store btw).

Any help is appreciated

Thanks

[Rails] backgroundrb misbehaving again

[Bharat Ruparel]

I have a really strange problem with Backgroundrb.  On one of my staging
servers, it is not recognizing the RAILS_ENV variable for some reason.
I have tried everything I could, that is:

a) stopping and starting from the command line by issuing the following
command

RAILS_ENV=staging script/backgroundrb stop|start

b) script/backgroundrb stop|start -e staging

c) from the Capistrano script, here are the relevant snippets:

  namespace :backgroundrb do
desc "Start backgroundrb service"
task :start, :roles => :app do
  run "RAILS_ENV=#{rails_env} nohup
#{current_path}/script/backgroundrb start 2>&1 1>/dev/null"
end

desc "Stop backgroundrb service"
task :stop, :roles => :app do
  # echo at end makes the return code always 0
  run "test -f #{current_path}/log/backgroundrb.pid &&
#{current_path}/script/backgroundrb stop; echo"
end

desc "Restart backgroundrb service"
task :restart, :roles => :app do
  stop
  start
end

  end

When I look at the log, it is clear to me that it is picking up the
development environment since the backgroundrb workers are looking for
the development database.  See the following snippet from the log:

Started reminders processing at: 2008-10-28 21:40:01

`find_delinquent'

 12286,1
99%

That 'isabont_dev' is my development database.  Why is it failing to
pick up the right environment all of sudden?  If it had picked up
staging then my database would be isabont_staging since that is how my
database.yml is configured.  What is bad is that this used to work fine
on the same server.  That is; I have deployed on this server using the
Capistrano deploy.rb many times before.  Exactly the same script works
fine on yet another server in another staging environment (for UK).

Seems like Backgroundrb is stuck on not recognizing the RAILS_ENV no
matter how it is passed to it and defaults to development since it is
trying to query the dev database.

Anyone has experienced this kind of inconsistent behavior in
Backgroundrb?


Thanks in advance for your time and apologies for the long post.

[Rails] rubygems-update 1.3.0 causing rake task problems?

[lunaclaire]

I'm running into problems with some of my rake tasks and I think it's
since my host updated rubygems to v 1.3.0.

Has anybody else seen this message?

   Gem::SourceIndex#search support for String patterns is deprecated

   ./script/../config/boot.rb:26 is outdated


that line of code is as follows:

   rails_gem = Gem.cache.search('rails', "~>#{version}.0").sort_by { |
g| g.version.version }.last

I doint think it's affecting my main app code... only the rake tasks.

Any ideas on what happended? Or how to fix this?

[Rails] Re: How to override one method of AssetTagHelper

[Rémi Gagnon]

Thanks a lot for the quick response!

BTW the reason why I want to override a method is because I need to 
support images for different locale.

for instance :

logo_fr.gif (for french)
logo_en.gif (for of course english)

In my view I want something like :

<% image_tag('logo.gif', :locale => cookies[:locale])%>

any better way?

Thanks again

So as I was saying, I remember apache killing off fastcgi instances. I
think it logs (or can be told to log) when it does this. If you can
correlate this with when you get the errors then you'll have found
your cause.

This has nothing to do with periodically_call_remote and everything to
do with it being an ajax request.
If you want to redirect from an ajax request you need to use rjs (ie
remove the update option from periodically_call_remote) and use
page.redirect_to from the rjs

[Rails] Re: attributes on join model

[ara.t.howard]

yeah i'm aware of all that - the issue is that using HM:T give no
simple method of getting back at the *particular* model/row used for
the join.  of course there can by more that one, but it's also the
case that for any given pair of related objects there is exactly one
row in the join model making that relationship and AR provides no
handle on this record, which makes decorating it rather tricky.

[Rails] Re: How to override one method of AssetTagHelper

[reHa]

Hi,

In our project we are using lib file as suggested

file name would be:
lib/action_view_ext.rb

module ActionView
  module Helpers #:nodoc:
module AssetTagHelper
  def image_path(source)
compute_public_path(source, 'images')
  end
end
  end
end

the best way to include the file !always! (doesn't matter if the
application helper is loaded or not)
is to add one line at the end of the

config/environment.rb

the line would be:

require 'lib/action_view_ext.rb'


Cheers

Hi,

Have you thought of using limit and a offset with a regular find?
(below is the code but I didn't check if it's valid)

current_offset = 0
limit = 100

begin
  result = MyModel.find(:all, :limit=>limit, :offset=>current_offset)
  #some operations
  current_offset += limit
end while result.size == 0

[Rails] File upload via non-browser REST call (using attachment_fu)

[Maximilian Schulz]

Hi everyone,

this might be a really stupid question but I have hit a wall here. I
already tried various different strategies but I really cannot find a
solution. The only thing which have not tried is to fake a browser
request, but I do not wanna go that far. So I hope I missed something ;)

Ok, finally our problem:
We have an application which allows file attachments for a model. We
implemented this feature with attachment_fu. Now we have the case, that
another application (a native windows app) needs to access this feature
via the API. We can create the model with no problem. But when it comes
to uploading files and adding them as an attachment, we have no luck
with the calls. Any idea or link what we are missing here? We simply are
not able to upload/access the file (always a 500 or something similar).

Thank you very much,

Max

[Rails] perooidically_call_remote

[Shandy Nantz]

I am using the following for to peroidically call back to the control to
see if a certain amount of time has passed:

in .rhtml
<%= periodically_call_remote :url => {
:action => 'session_expiry' },
:update => '' %>

in controller
 if !session[:expire].blank?
   @time_left = (session[:expire][:expires] - Time.now).to_i
 else
   @time_left = 0
 end

 if @time_left.to_i < 0 or @time_left == 0
   flash[:notice] = "You have been logged out
due
 to inactivity"
   session[:user] = nil
   redirect_to :action => 'login'
 end

The idea being that if too much time has passed the user gets signed out
and get kicked back to the login page. Everything work right, except the
bit of code that check to see if an hour has passed since the users last
action and then it is supposed to redirect_to a login form. The problem
is that when it gets to that redirect_to it seems to skip right over it
and not do anything, even worse, it allows the user to continue to be
logged in. Has anyone used peroidically_call_remote before and has
similar issues and how did you fix them? Thanks,

Would you just link them together with generic html links into there 
respective controllers? or is there a way to link them together with 
rails?

my generic plan atm is to have a main page with our logo and a 
navigation bar for each department, then under that a feed aggrigator 
with industry news in it.

   logo
   finance  hr  it  sales  etc

  industry feed   industry feed  local weather

asci doesn't do many things justice

each department listed above will have a dropdown menu with a few items 
in it that would be the applications.

this part will also obviously be a rails app

I may be misremembering, but I have a vague idea that this can happen
if the mongrel/whatever is sent a TERM signal. How is your app
deployed? (in particular I seem to remember apache being a little
enthusiastic about killing fastcgi instances)

Broadly speaking I'm on the side of multiple smaller rails apps than
one huge one. Easier to write, easier to maintain. The answer also
depends to an extent on what levels of interaction you need between
the apps.

[Rails] attributes on join model

[ara.t.howard]

given a setup like

class Parent
  has_many :child_parents
  has_many :children, :through => child_parents
end

and assuming i'd like to store the style of relationship on the
child_parents table, for example

create table child_parents(
  parent_id
  child_id
  is_adopted
)

in otherwords, 'is_adopted' is an attribute of the link between child
and parent, not of the child or parent themselves, how can one access
this simply?

child = parent.children.first
p child.adopted?

is obviously desirable and used to be possible with HABTM
associations.  but that's deprecated however there seems to be no
easy way to accomplish something similar with full blown join models.

cheers.

[Rails] intranet applications

Hello,

I am getting ready to start building an intranet for a small company i
work for. I have a question about the general architecture of such a
thing. the intranet itself will contain multiple applications for
various departments. what i am trying to figure out is if i should start
by making each application as a seperate rails project or attempt to
design it from the top down, all in one project. I have a feeling i am
not being very clear here so please feel free to ask questions, also

I am having this same problem.  It seems the before_validation isn't 
working in mine:


before_validation :normalize_phone_number

validates_format_of :number,   :with => /^[0-9]{10,15}$/

protected

def normalize_phone_number
  self.number.gsub(/-/,"").gsub(/ /,"")
end


The object won't save since it fails the validates_format_of since it 
never runs the before_validation.  I'm running Rails 2.1.0.

Any ideas?

[Rails] Random SystemExit. ActiveRecord::StatementInvalid

[Carlos Garcia]

I have this recurrent problem that I just can't figure out. On several
parts of the application when active record is executing some query it
throws a ActiveRecord::StatementInvalid exit like this:

A ActiveRecord::StatementInvalid occurred in
someapplication#some_action:

 SystemExit: exit: SELECT * FROM project WHERE (project.`id` = 9)
 
/usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/connection_adapters/abstract_adapter.rb:128:in
`log'

The thing is that the next time you try the same action, it works fine,
also if you run that query directly in a console or any query browser it
returns a valid result. The occurrence is very random.

Any help or comments are greatly appreciated.

Hi Josh,

could you post some source code (of "add" action for example) and some
more info about your production env? Do you display flash messages in
your layout or view files? If in view files, do you include it on the
page where it is missing?

Best,

Unless I'm totally wrong on what you're trying to do, here's some  
pseudocode on how I see it:


37.4419, -122.1419put any  
content for your marker here
38.4523, -121.1887put other

Javascript pseudocode (won't work, but you get the picture):

$('positional-data').select('li).each(function(el) {
new GMarker(new google.maps.LatLng(el.down('em').innerHTML),  
el.down('.content'));
});

I won't guess what snitko wants to do (his list of reasons may or may
not be comprehensive), but I will say that snitko should choose a
license which is appropriate for his goals.  For better or worse his
stated goals aren't really legally enforceable.

I see Teachmate.org is GPLv3 and know at one point in time RMS was
complaining about websites using GPL'd code but since they weren't
redistributing binaries they didn't have to share their improvements-
I don't recall if/what changes were made in the GPLv3 to address this.

[Rails] Re: Ruby console problem

[Hubert Łępicki]

Hi Lawrence,

I am not an expert on Windows, and generally - ruby is painfully slow
in this environment, so you should consider switching to Linux or Mac
OS if you want to use ruby with comfort in long term, but I think I
know what's your problem.

Seems to me that InstantRails opens console windows for you, and sets
some environmental variables, like PATH to make it possible to use
ruby.
If you type "irb" in normal console window, you'll get "no such
command" or similiar, while started from menu - will spawn irb for
you.

You might need to navigate to your rails project in command line,
like:
> cd C:\myprojects\rails\blog

and run console:

> ruby script\console

Please let me know if this helps,
Hubert

[Rails] Re: Ruby application talking to Java application (IPC suggestions please)

[Hubert Łępicki]

Hi,

I went third route. I couldn't use web services as I was clearly told
not to use any Java web container. I also couldn't use jruby, as I am
dependent on some C++ libraries. Fortunately, there is nice library
Ruby Java Bridge (http://rjb.rubyforge.org/) that helped me get around
this issue and include my Java classes into project directly. Can't
say much about resources consumption/memory leaks or stability yet,
but all looks good for now.

Thanks,
H.

I think the key takeaway is that the term "open source" has nothing to
do with where the code actually runs (see disclaimer below).  It has
to do with who has access to the code and what they can do with the
code.  By opening up the source code according to most OSS licenses,
it's perfectly valid to take the code, rebrand the site and start a
competitor site- just like there have been forks of traditional
software (Emacs vs. XEmacs for example).

* Disclaimer: Depending on the license used I may not even have to
redistribute the changes I make to my competitor site (BSD, Artistic
and GPLv2 for example).  Of course some licenses have special clauses
for "web delivered applications".  So yes, where it runs is a factor
in the "redistribution" clause, but most OSS licenses don't force you
to share code changes for web applications.

[Rails] Scaffolding and dealing with generated actions in the controllers

[command0]

Hey Everyone,

I wanted to know if I could get some insight on something. I am using
Rails 2.1.2 and for something that needs beyond basic functionality, I
typically generate a scaffold so I don't have to manually create
everything and save some time. Well as you all most likely know, along
with generating a scaffold, comes predefined actions in the controller
that is generated, usually like show, new, create, index, etc...

The question I have regarding that is how and where are all those
actions tied to? I know Rails 2.* uses the REST model by default, so
everything is resourceful. And thats fine and all, but when I want to
do something outside of those predefined actions, it throws a fit so
to speak.

Let me illustrate what I mean by that. So lets say I wanted to create
a Rails app for a local brewery that has a UI frontend that would act
as the brewery site lets say which also contains a catalogue of their
various lagers and ales that they have for sell to take home. So I
would create an app called brew lets say - "rails -d mysql brew".

So the skeleton is created, but now I need a model, view, and
controller of course. I decide this needs a bit extra functionality
from the get go so I create a scaffold - "script/generate scaffold
beer". I generate a new migration for the table needed to store all
the various products that the brewery offers - "script/generate
migration add_products". I write in the fields that I want in the db
table, and run a rake db:migrate. Everything is great.

Now I can add a couple products, and show the details of them. Great.
But now, I want to do more than that. Now I want to be able to write
in a mashup into the app also so maybe someone could find the place,
so I'll integrate google and yahoo maps in with the GeoKit plugin, and
I want to play some videos on youtube that related the brewery
assuming there were any, so I'd use the YouTube API using something
like the YouTube-G plugin or something.

So now I install the plugins, and then write some methods into the
controller to act as something like a search functionality. But now
that say these methods are wrote, and I have a template called
search.rhtml in my view that will generate directions to the place
using the users remote public ip and geocoding that into coordinates,
then pulling up any youtube videos on a sidebar that has to do with
the place.

So I make sure everything is saved, and I fire up mongrel and test it
out. But instead of seeing the generated html form, instead I get an
action controller exception saying "Cannot find with ID=search" or
something to that affect, and I get lines that describe where it is
derived from, but it would be in the controller on the line with the
"def show" method, containing something like @beer =
Beer.find(params[:id]), in which is is querying for the sql id field,
which is the primary key in the table. But because I'm trying to find
anything but ID, it fights me tooth and nail.

So, I wanted to know if anyone really understand REST, and how
everything ties together. I have tried to delete the
map.resources :beers (or whatever it may be), but then it has a
routing issue. I am but I try to do anything beyond the basic methods
laid out in the generated controller and it throws a big fit.

Can anyone clarify this for me so I could understand it better?

[Rails] Re: How to override one method of AssetTagHelper

[Rémi Gagnon]

Thank you, you are really right I should put it in my 
application_helper.  But Here we will have a lot of projets and I want 
to share this kind of changes to all teams.  So that's why I would like 
to ultimatly put it in a gem.

So I'm curious to see how you would include mymodule on

[Rails] follow_redirect persistently breaks ActionController verify

[Fritz Anderson]

I've narrowed the problem a bit. It now seems that follow_redirect in 
one test will break an ActionController's +verify+ directive in another, 
later test.

I am ashamed to say my code fragment was not accurate. Here is the 
correct code:

==
class AdminControllerTest < Test::Unit::TestCase
# #setup puts user credentials in @session

def test_approve_not_post
get :approve, { :id => 3 }, @session
assert_response :redirect
assert_redirected_to :action => :list
assert_equal 'You cannot do this directly.', flash[:notice]

### OMITTED IN ORIGINAL - SORRY ###
follow_redirect
assert_response :success
end

def test_deny_not_post
get :deny, { :id => 3 }, @session
assert_response :redirect
assert_redirected_to :action => :list
assert_equal 'You cannot do this directly.', flash[:notice]

### OMITTED IN ORIGINAL - SORRY ###
follow_redirect
assert_response :success
end
end
==

Note that I have the tests follow the redirect_to arising from the 
failed +verify+.

I have discovered that if I comment-out the follow_redirect and 
assert_response calls in test_approve_not_post, then +verify+ will 
redirect correctly in test_deny_not_post. Remember it was the 
assert_redirected_to, and the redirection hash, that broke.

So now: follow_redirect breaks an ActionController's +verify+ handling. 
before_filter and after_filter don't have this problem. Is this a 
peculiarity of functional tests -- and can I therefore ignore it? I'd 
rather be able to test the redirection.

Should I update beyond Rails 1.2.6? 2.x is not feasible for my 
deployment.

Again, I'm sorry about mischaracterizing the code.

[Rails] Page does not seem to be reloaded on prod server

[Joshua Muheim]

Hi all

I've coded a small shop that works well on my dev machine (OSX 10.5).

But look at the following page:

http://shop.incense.ch/compact_discs/1

When clicking "Reservieren", the page is forwarded to a new page, where
the product is added to the shopping cart, and a flash notice is
prepare. Then the page is redirected back to the shop page.

On my dev machine this works well. But on the production server this
doesn't seem to work! But look what happens when you click on another
link, e.g. "Kontakt"! There the stuff seems to be!
What the heck? Never stumbled over this before...

Anyone has an idea what's wrong here?

Thanks
Josh

[Rails] Iterating through all model records without pre-instantiating them

[Pilaf]

Hi,

I'm writing a migration script which has to, well, actually migrate
all data from table A to table B, but I need to access the application
logic in model A for each row migrated. I could do this:

MyModel.all.each do |instance|
  # do stuff...
end

but as far as I know that would pre-instantiate all records in memory
beforehand, which could be *really bad* with the amount of records I'm
dealing with, and I only really need to work with a record at a time.
An alternative I'm currently using is:

execute("SELECT * FROM table_a").each_hash do |row|
  instance = MyModel.new(row)
end

but I believe this is also sub-optimal (especially since some
attributes are attr_protected, therefore I'm having to take care of
those manually, and other reasons).

Is there any obvious/elegant way of doing this I'm missing?

Thanks,

-Pedro

[Rails] How to override one method of AssetTagHelper

module ActionView
  module Helpers #:nodoc:
module AssetTagHelper
  def image_path(source)
compute_public_path(source, 'images')
  end
end
  end
end

But as soon I try this all the others methods from the overriden module
are not available anymore.

Any idea?

[Rails] Re: TeachMate.org goes opensource

[Jean-Marc (M2i3.com)]

Well the major distinction between a website and a local application
is precisely that... where it runs.

Lets take OpenOffice...

You download a copy and run it on your machine.
You can choose to alter your copy and be the sole user of those
changes
You can publish your changes and once approved/merged into the trunk
version, other people can benefit from it.
** The benefit of the improvements made takes a longer time (if ever)
to reach the potential users.

Lets take Joomla...

You download a copy and run it on your webserver
You can choose to alter your copy
You can publish your changes but there again people will need to
update their own copy.
** The benefit of the improvements made still takes a longer time (if
ever) to reach the potential users.

Lets take teachmate.org  and reddit.com...

You don't download anything unless you want to change it (or branch
and start your own)
Whoever have their published changes approved updates the final
website directly.
** The benefit of the improvements reaches all the users upon
approval.

Lets imagine Google was doing it where you could download the source
code of their website and suggest improvements to any aspect of it
where the whole user base of Google would benefit from the changes.


The distinction is probably too thin to justify a new term... "Open
Source Website" already says enough.  But new terms also carry with
them loads of meaning and in the case of Reddit and Teachmate the
meaning is: "the website, it's behavior and all aspects of it belongs
to the community an is actively maintained by the community".

@temp_download_file_path = session[:temp_file_path]
send_file @temp_download_file_path,
 :x_sendfile => true,
 :type => 'text/csv',
 :filename => "contacts.csv"
  end

No errors are generated.  Log says it is sending it.  I wind up with an
empty ( 1
byte) file on the other end.  I get the same results with and without
the "x_sendfile".

Any advice on where the file should reside on my server and how to set
the necessary permissions to allow send_file to get at it?  What else
could I be doing wrong?

Thanks for any additional help you guys can provide.

I believe I'm running Ruby 1.8.7 from source.  Again, being a complete 
nube, I really have no clue which file(s):

Macintosh-3:~ johnclaus$ ruby --version
ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-darwin9.4.0]

I'm also running Leopard 10.5.5.

[Rails] Sudden failure of redirect in ActionController +verify+

[Fritz Anderson]

= SUMMARY

An ActionController +verify+ directive redirects to an :action if
certain actions are not done by POST. In one case, the redirect is to an
empty hash instead; in another, nearly identical, it is to the correct
hash. This is seen in a functional test.

Will someone please tell me what is going wrong, and how I can correct
it?


= ENVIRONMENT

$ ruby --version
ruby 1.8.6 (2008-03-03 patchlevel 114) [universal-darwin9.0]
$ rails --version
Rails 1.2.6


= DETAIL

(Much of this may be easier to see in the "CODE" section, below.)

AdminController is a subclass of ActionController, acting on instances
of Permission, an ActiveRecord subclass. Permission#approve and
Permission#deny set the :approval attribute to one string or another.
admin/approve/:id and admin/deny/:id pass the respective methods to the
id'ed Permission.

AdminController has a +verify+ directive to require that #approve and
#deny be done by POST. If they are not, the session is to :redirect_to
admin/list.

Class AdminControllerTest, a Test::Unit::TestCase, challenges the
+verify+ by using GET requests instead. For many iterations of the test,
AdminController passed. I then added some tests to AdminControllerTest;
I did not change test_deny_not_post or test_accept_not_post.

test_deny_not_post then started failing at assert_redirected_to. The
fail message is:

"response is not a redirection to all of the options supplied
(redirection is <{}>), difference: <{"action"=>:list}>"

test_approve_not_post, which is nearly identical, DOES NOT fail.

Changing the +verify+'s :redirect_to to { :controller => :admin, :action
=> :list } gets the tests past the assert_redirected_to, but fails the
follow_redirect (Can't follow redirects outside of current controller
(from admin to admin)). This failure is in BOTH test_deny_not_post and
test_approve_not_post.

My controller is failing a functional test, and I don't understand why.
Will someone please tell me what is going wrong, and how I can correct
it?


= CODE (abridged)

class AdminController < ApplicationController
   verify :method => :post, :only => [ :destroy, :create, :update,
:deny, :approve ],
  :redirect_to => { :action => :list },
  :add_flash => { :notice => 'You cannot do this directly.' }

  def approve
 # before_filter sets @permission
 @permission.approve
 if @permission.save
flash[:notice] = 'This request was approved.'
 else
flash[:notice] = 'Could not approve the request (internal
error).'
 end
 redirect_to :action => :list
  end

  def deny
 # before_filter sets @permission
 @permission.deny
 if @permission.save
flash[:notice] = 'This request was denied.'
 else
flash[:notice] = 'Could not deny the request (internal error).'
 end
 redirect_to :action => :list
  end

class AdminControllerTest < Test::Unit::TestCase
  # #setup puts user credentials in @session

  def test_approve_not_post
   get :approve, { :id => 3 }, @session
   assert_response :redirect
   assert_redirected_to :action => :list
   assert_equal 'You cannot do this directly.', flash[:notice]
  end

  def test_deny_not_post
   get :deny, { :id => 3 }, @session
   assert_response :redirect
   assert_redirected_to :action => :list
   assert_equal 'You cannot do this directly.', flash[:notice]
  end
end

As someone who is also working on an open source website, I'd love to
hear your reasoning for suggesting a different term.  Why does it
matter if it's a website or code which runs locally?

[Rails] Re: Rails 2.2.0 and Gettext incompatible?

[grosser.michael]

Htis is only the top of the iceberg,
render_file can be fixed by patching gettext, but the rest of
gettext must largely be rewritten, since rails does not use class-
instance variables(@@) anymore
for thread safety reasons

therefore my guess is that the next version of gettext could take some
time...

[Rails] Passing a function with arguments to another function with arguments that is a loop

[tyliong]

Hi, I am a noobie. I just want to know what is the standard or most
effective way of doing this

I have two functions


def display_price(grocery,batch)
grocery_price = grocery.send(batch).price
if grocery_price
number_to_currency(grocery_price)
else
"NA"
end
end

def loop(func,matrix)

matrix.each { |matrix| display_price(@grocery,matrix) }

end


the "func argument" in the loop function is suppose to be
display_price but how do i put it in if the "batch" is the thing that
I want to be looped through?

Yes, that seems to be the problem. But I double-checked my parameters 
(which work for another, though newer RoR app), and it still gives the 
same error.

My db params are:

development:
  adapter: mysql
  database: bergschmuck_development
  username: XXX
  password:
  socket: /tmp/mysql.sock

[Rails] Old Rails app: strange problem with getaddrinfo

[Joshua Muheim]

Hi all

I'm trying to get an old Rails App (RAILS_GEM_VERSION = '1.1.6') to work
again;

Strangely I get the following error on most pages, and I don't have any
idea where it could come from:

 SocketError in Startseite#index

Showing app/views/partials/_menu.rhtml where line #6 raised:

getaddrinfo: nodename nor servname provided, or not known

Extracted source (around line #6):

3:   unikat_subitems = []
4:
5:   shop_subitems = []
6:   produkt_typen_for_produkt('MassenArtikel').each do |id|
7: produkt_typ = ProduktTyp.find_by_id(id)
8: shop_subitems << {:caption => produkt_typ.name, :action =>
:produkt_typ, :id => produkt_typ}
9:   end

Web Services; RESTFUL or otherwise.  Though you can do SOAP on Rails, I
recommend picking up "RESTful Web Services" by Leonard Richardson and Sam
Ruby.

On Windows, I think you need 1.2.3 - so you should do:
gem install sqlite3-ruby --version 1.2.3

That should get it working.

[Rails] Re: RESTful resource with multiple view representations

[Andrew Edwards]

Thanks, I think I looked at something similar to a mode/context param
previously but seemed to drift away. I might have another look.

In this scenario are you suggesting sticking the conditional logic
against the mode param in the action RJS view?

@display_context = params[:context]

respond_to do |format|
 format.js
end

Is there a way to specify the specific RJS file in the action?

Concept (format.js lines not necessarily valid, just to show
intention):

display_context = params[:context]

respond_to do |format|
 if display_context == "sales"
format.js { :render => 'sales_products' }
 if display_context == "purchase"
format.js { :render => 'purchase_products' }
 else
format.js { :render => 'products' }
 end
end

First off, what about using the same search action for each, and using
query parameters to specify the desired behavior?  That way you won't
need a new custom action every time you need a new "flavor" of search
call.  It's perfectly RESTful to append any query parameters you need
to your actions (/products/search?mode=purchase, or whatever).

However, maybe you really need a separate controller entirely, like a
ProductSearchesController, whose index action can take whatever
parameters you think are appropriate.  That might help encapsulate all
of your searching functionality and keep the ProductsController
restful and clean.

Just some ideas

you can do that anyway - :joins accepts arbitrary sql fragments.

Does anyone know if there are any plans to allow conditions to be

[Rails] RESTful resource with multiple view representations

[Andrew Edwards]

Hi,

Could somewhat offer guidance on this situation.

Say I have a Product model and an associated resource reference
defined:

map.resources :products, :collection => { :search => :get }

I need to access the search action but have a different view
(generally RJS) rendered depending on the context of the call.

For example, if called from an order assembly page I might need the
resulting product collection displayed with add to basket links.
Whereas on another page I might need them rendered with add to
purchase order links.

I see to obvious solutions:

1. Define multiple actions within a single resource. They would
essentially have the same code but would call different RJS view code
to render the result.

   map.resources :products, :collection => { :sales_order_search
=> :get, :purchase_order_search => :get }

2. Have multiple resources such as as:

   map.resources :sales_order_products, :collection => { :search
=> :get }
   map.resources :purchase_order_products, :collection =>
{ :search => :get }

If going down route 2 I'd probably just repurpose the index action to
check for a search_string param to narrow the results returned.

Both seem less than perfect, although I'm tended towards solution 1.
Although I've only highlighted two view contexts there could be more,
I would suggest 3 or 4 could be common. How would you handle this
situation?

Thanks, Andrew
