[Rails] Re: Calling Rake from INSIDE the application

[Freddy Andersen]

def run_task
  result = %x(rake #{params[:rake_task]})
end

If you don't want to hold the thread you can install the crontab gem
and install a new crontab with a ts:in or use background-fu and push
the job to the background...

[Rails] Re: Rails on shared hosting

[Bobnation]

I tried running a Rails app through cPanel a long time ago and gave up
because I like to have finer control over everything. If money is not
too much of an issue, I think you would be better served by signing up
for a VPS from somewhere and then setting up your own virtual server
to run the app on if for no other reason than to gain a good
understanding for how Rails applications are served to your audience.

[Rails] Re: Rails on shared hosting

[James Englert]

Rails would need to be installed.  Do you have an .htaccess file that
resides in your public_html directory?  If so, that file is crucial for
getting your app up and running.

Dusty,

That may very well be it. I thought it was a longer list, but maybe
I'm just remembering the two lists (new vs. existing) and somehow
lumping them together.

Thanks for the reference, though! :-)

[Rails] Re: valid? is not working in Rails 2.2.2

[Vipin Vm]

Hi All,

My project was started in 1.2.6 then i upgraded to 2.0.2. Last week i 
updated it into 2.2.2. Then i got this problem. Then i again moved it 
back to 2.0.2 and it worked fine. These are the changes i have made in 
my config files.

in env.rb :-
RAILS_GEM_VERSION = '2.2.2' unless defined? RAILS_GEM_VERSION
config.time_zone = 'UTC'
config.threadsafe!

database.yml:-
pool: 10
wait_timeout: 10

when i upgraded to 2.2.2, got a new file called new_rails_defaults.rb in 
initializers folder.

I created a new project in 2.2.2 and connected to my original db. its 
also working fine.

[Rails] Calling Rake from INSIDE the application

[Dante Regis]

Hey there
I would like to know if I can call a rake task from inside my Rails App.
Something like

class MyModel < ActiveRecord::Base
  after_save :run_task

  def run_task
Rake.run("my:little:task")
  end
end

This is the deal: I use thinking-sphinx and need to update a bunch of data
through Model.update_all. But I would like sphinx to index it just after I'm
done, by running rake ts:index.

Is that possible?

Thanks,
Dante

[Rails] ActionMailer, unit testing and multipart mails

Hi all.

Is there a "correct" way of writing a unit test for a mailer which

I tried using the @expected variable as provided in
ActionMailer::TestCase, but it led to various problems.

Here's what I'm attempting...

Line 16 is commented in the above code.  Looking at mail.rb:551
suggests that body is nil, and I can confirm that the body passed in
was not nil.

I know I can just not use @expected and check each bit of the mail
separately, but I figure @expected is there for a reason (and also,
checking each bit of the mail only verifies what is supposed to be
there, not what isn't.)

Maybe I'm just doing things completely wrong, as I'm not 100% used to
Rails 2.x yet.

[Rails] Can I export db data to fixtures?

[Arthur Chan]

Hi Guys,

Is there any way to export db data to fixtures files?

(like the reverse of  "rake db:fixtures:load")

Thanks,
Arthur

[Rails] form_for with partial using do |@f|

[Richard Schneeman]

Is it possible to pass this FormBuilder object to a controller and then
back to a partial?


I have a form rendering a partial that i would like to update with a
call to my controller based on user selectable parameters, but when the
AJAX comes back, i get this error message because i cannot pass a form
builder object between the controller and the view:

"undefined method `text_area' for
"#":String"


My View looks like this:

<% form_for @phrase, :action => 'foo' do  |@f| -%>

 <%= select_tag(:language,
options_for_select(["Chinese","English"],
  :onchange=> remote_function(:with =>
  "'language='+this.value",
  :update => 'slang_form_partial',
  :url => {:action => :something,  :form => @f}
)) %>

 <%= render :partial => 'forms/slang_form_partial'%>

<%= @f.submit %>



In my controller i have something that looks like this:

  def something
  @default_language = params[:language]
  @f = params[:form]
  render :partial => 'forms/slang_form_partial'
end





Is it possible to pass this FormBuilder object to a controller and then
back to a partial? Rails 2.1.0 and Ruby 1.8.6.

[Rails] Non-Profit Start up

[Marvin Arnold]

Hi,
My name is Marvin Arnold. I am a junior at MIT in EECS. I am starting a
non-profit, uService, with the mission of getting more college students
volunteering.

Although uService is a non profit, it has a unique and scalable business
model, that promises much future success. We are looking for a few
developers to join our team. If you are interested in learning more
about the organization (or have suggestions on better places to post)
please send an email to maarnold [at] mit [dot] edu.

Thanks,

[Rails] Optional parameter in nested routes

[Constantin Gavrilescu]

All my charges belong to a company. On the new charge form, sometimes I
specify a company, sometimes I don't because I don't know the company
beforehand in all cases.

So, sometimes the @company object is nil.
I'm using this helper: new_company_charge_path(@company)
For a company object, it generates a path like
/companies//32/charges/new
For a nil object, it generates a path like /companies//charges/new, but
I get an routing error (No route matches...).

I don't want to use an if in my view to use either new_charge_path or
new_company_charge_path. I reckon that /companies//charges/new can be
parseable and rails can recognize the path. Any ideas?

map.resources :charges
map.resources :companies do |company|
company.resources :charges
end

[Rails] Re: Rails on shared hosting

[Nellboy]

As far as I know (and that's not much in this case), then Rails needs
to be installed by the hosting provider... and i'd say your chances of
making that happen are somewhere between nil and none... Maybe there's
some workaround to this, I know that phusion passenger allows
deployment to Apache webservers, but I haven't used it, so I don't
know about this case (although any day now i'm gonna investigate
it)... maybe there's another solution anyone??

Hey,
Thanks for the reply. The assert !l.valid? did not help. I still get the 
same error.

When I run the command with the --trace command, I can see that rake 
fails right after the execute db:test:purge step. I have included the 
trace.

** Invoke test:units (first_time)
** Invoke db:test:prepare (first_time)
** Invoke db:abort_if_pending_migrations (first_time)
** Invoke environment (first_time)

** Execute db:test:prepare
** Invoke db:test:load (first_time)
** Invoke db:test:purge (first_time)
** Invoke environment

rake aborted!
You have a nil object when you didn't expect it!
You might have expected an instance of ActiveRecord::Base.

Sorry for my ignorance but could you explain how would you do that. How 
would you yield and concat? A quick example would be worth a 1000 words

Perhaps another clue, maybe this will ring a bell for someone.  I'm
now slowly removing all of my views, running script/about after I
remove each one, and now I got this error:

$ script/about
/usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in
`gem_original_require': no such file to load -- rails/info
(MissingSourceFile)
from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in
`require'
from /home/jcohen/sites/pw/releases/20081201224923/vendor/rails/
activesupport/lib/active_support/dependencies.rb:155:in `require'
from /home/jcohen/sites/pw/releases/20081201224923/vendor/rails/
railties/lib/commands/about.rb:2
from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in
`gem_original_require'
from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in
`require'
from script/about:3

I can start script/console, and checking $LOAD_PATH reveals a few
differences from what's on my Mac OS X.  Here's what I get on my Mac,
for example:
>> $LOAD_PATH.select { |p| p =~ /railties/ }
=> ["/Users/jcohen/dev/pw/config/../vendor/rails/railties/lib/../
builtin/rails_info/", "/Users/jcohen/dev/pw/vendor/rails/railties", "/
Users/jcohen/dev/pw/vendor/rails/railties/lib", "/Users/jcohen/dev/pw/
config/../vendor/rails/railties/lib"]

Notice that first path to builtin/rails_info.  Doing the same on my
Ubuntu/Ruby 1.8.7 box shows this:

>> $LOAD_PATH.select { |p| p =~ /railties/ }
=> ["/home/jcohen/sites/pw/releases/20081201224923/vendor/rails/
railties", "/home/jcohen/sites/pw/releases/20081201224923/vendor/rails/
railties/lib", "/home/jcohen/sites/pw/releases/20081201224923/
config/../vendor/rails/railties/lib"]

In other words, the path to railsties/lib../builtin/rails_info is not
there!  And if the load path is messed up, then I bet other things are
also.

I've tried unfreezing rails and using 2.2.2 gems, with the same result
- so it's not the result of a borked version of vendor/rails.

Any ideas?

Thanks
Jeff

[Rails] Rails on shared hosting

[Joshua Partogi]

Dear all,

Has anyone run RoR on cPanel based shared hosting? I've got my RoR
application on http://mydomain:10024/

Now I've uploaded all my Product model, view and controller.

Then I tried hitting: http://mydomain:10024/products but it didn't work

Is there any configuration I need to do on a shared hosting? Has
anyone experience with this before?

I'm sorry I have to ask it here since the hosting provided weren't
very supportive as they said it's the problem with the apps, but this
seems to be a relatively simple question :-(

Thank you in advance for the support.

[Rails] call_rake results in sh: /opt/local/bin/rake: No such file or directory

[Rafael]

Hi

On my Linux Production Box, a Background Process results in following
error:

(rdb:5) call_rake(:send_mailing, {:mailing_id => params
[:id].to_i, :rails_env => Rails.env})
sh: /opt/local/bin/rake: No such file or directory

The strange thing is, that actually the path is set correctly.

-bash-3.1# sh
sh-3.1# which rake
/usr/bin/rake
sh-3.1# bash
bash-3.1# which rake
/usr/bin/rake

Does anybody has a clue, why / where I have to set this path, so that /
usr/bin/rake is taken as a valid path?
Thank you very much!

regards

Rafael

[Rails] Re: ActionMailer weirdness: bad html '=3d' for all '='

[minka]

the content type is text/html.
Where and how should I specify encoding?
Is it this:

 mail = TMail::Mail.new
 mail.transfer_encoding = "something"

What should "something" be?
this email is plain, vanilla, simple, nothing fancy, no special
characters, etc.
I just want something plain, simple etc that WORKS on ALL mail
servers.
thanks much!

That is correct and the statuses method probably isn't even defined in the 
context you are using this in. The write way to do this is to put

status: active

in that fixture. As long as you have the status belongs_to association, rails 
will figure out that this means that you want the status_id column to have the 
value of the id of the status fixture with label 'active'. This won't work if 
your fixture for statuses explicitly sets an id.

You might find this interesting -- it's a kind of explanatory scaffold, so to 
speak, for REST in Rails:

http://dablog.rubypal.com/2008/11/24/restful-rails-for-the-restless

(Or you might be past the point where it's useful, but I thought I'd throw it 
out there just in case.)

The email was encoded with quoted-printable. In that encoding = is a
special character so is escaped with =3D.

You can set the transfer encoding to something other than quoted-
printable (eg not encode at all), but if you don't encode at all the
mail could get garbled when passing through some mail servers. There's
an example in the docs of how to set the transfer encoding to base64,
you could instead just set it to 'identity' (actually actionmailer
won't do any encoding if that setting is not either quoted-printable
of base64 but you might as well pick a sensible name)

If your email is indeed html, why are you setting the content type to
text/plain ?

email = OrderMailer.create_price(@order)

Unless you had frozen rails, you could be running a different version

I know nothing about instant rails but it would be insane if you

[Rails] Re: localhost redirect/404

Hmm, I've noticed this problem only occurs if I type "localhost:3000" in 
the browser (without the http protocol).

So, no worries, although it is curious, I know how to properly access 
stuff now and have a better idea what to search on.

[Rails] Incompatible versioning of InstantRails?

[Scott Peterson]

I'm trying to get InstantRails running on a different computer than I
originally started and I've gotten stuck.  I kind of think it's a
versioning issue, but don't have a real good "reason why" I think that.

Here's the deal.  I'd started fooling around with Rails a while back on
my laptop and got to a point where I did a check-in to an svn
repository.

This turned out to be a good thing, as that laptop went away for a
while.

So, I've downloaded InstantRails 2.0 to my desktop, got the database set
up for this application, and recovered the Ruby code from the
repository, putting it in rails_apps.

I then did a 'rails ' to make sure it would show up in the
Rails Applications window, and asked the system not to overwrite any
files it asked to.  So I believe I have the same setup as was on my
laptop, with the possible exception of the version of InstantRails.

When I try to start this application, I see the window start and shut
down almost immediately.  I don't see anything in the /log directory to
help me out.

I'm kind of guessing that I didn't originally develop in 2.0, so there's
an incompatibility between my code and this framework.

Can anyone verify that could be a problem, or put me on a path to
further debug this issue?

Thank you.

Perhaps you need a line between 6 & 7 with:

assert !l.valid?

Otherwise the error object associated to the model will not have been  
created.

Really cool trick. It's exactly what I was looking for. Do you have any 
idea how to combine visual_effects? The doc for scriptaculous is broken 
at github, it misses the demo page.

That's basically what we do. Separate apps have separate databases and
never touch the database of another app (so it's dead easy to isolate
an app (eg if it needs more horse power than the others or if it is
criticial) by just running it off a different database server.
Apps usually communicate with each other via private APIs over http.
Depending on how your app works you may find that ActiveResource is
useful, most of our interapplication communications don't really fit
with that model and so we haven't used that much

I would avoid synchronizing data, sounds like a headache (the only
place we do this is with our single sign on system, so that apps can
operate when it isn't available)

You may be wondering what to do when you want to display data from two
apps on the same page. The way we do it is to have javascript objects
on the page that fetch content from the different apps via ajax. A
single page may contain fragments of html rendered by any number of
applications.

My colleague and myself presented on this subject at railsconf europe
2008. The slides should still be available, as well as demo code used
in the presentation. Both should be linked from
http://www.texperts.com/2008/09/08/code-from-the-railsconf-europe-presentation/

Well you could probably do it by messing around with bindings and eval
but that sounds like a sucky design. why not do something similar to
form_for, ie your my_cool_block method yields an object encapsulating
the state you want to share in its instance variables. usage could be

<% my_cool_block(5) do |helper| %>
  <%= helper.some_helper_method "My var %>
<% end %>

you could do other stuff too, eg call helper.with_value(5) and for the
block passed to with_value, my_var would have value 5

[Rails] communicating between multiple rails applications?

[Stedwick]

Short story:

My company has a rails application as our product. As we add more
functionality, we are thinking of building new small, self-contained
rails applications rather than just chugging along with our single
monolithic application that we have right now.

What is the best way to do this? Is it even recommended?

Long story:

My company, www.readMedia.com, specializes in press release
distribution over the web and our product is a 60,000 line Ruby on
rails application. We want to start adding some functionality that
sort of has to do with existing functionality, but not really. It
would use most of the same data, but the product could be sold
separately to new clients, or as an add-on to old clients.

The easiest thing to do would be to simply build that functionality
into our existing application. However, that has some drawbacks. As
the application gets bigger and bigger, and we hire more programmers,
the testing gets harder, the organization gets harder, deployment gets
harder, the code gets messier, et cetera.

What we would like to do instead is to build new functionality as a
separate rails application entirely. This has many advantages. Each
application/functionality can be upgraded independently, turned on or
off at will, have its own team of programmers who never have to worry
about stepping on the feet of other teams, source control becomes
easier, deployment is easier, et cetera.

The problem, to me, is that this seems to be technically really REALLY
hard, if not impossible. It sounds wonderful in theory, but can
(should) it even be done? Although the functionality of each
application would be different, they would share most of the same
data, such as our geographic table of zip codes and counties and our
history of sent releases.

One thought is to use the same database for each application. This
seems really tough. How would we keep the models in sync with each
other, because things such as validation is very important? Another
thought is to use multiple databases, one with the shared information,
and another for each application to hold its own stuff. Again, very
difficult. As far as I can tell, rails simply can't use multiple
databases. I've found a plug-in or two that supposedly does this, but
I'm not sure I would trust it.

Another thought is to have some API between the old system and the new
applications that we are making. Although certainly possible, this
seems like an extraordinary amount of work. How do we secure
communication between applications? How do we share user accounts?
Making an API would basically mean re-creating all of the existing
functionality in an outward facing manner that can be called from
another application. I don't really know how to do that, nor do I have
any experience with that sort of thing.

Another thought is to synchronize the data occasionally between our
applications. Have a background task that runs every night and updates
each database in sync with each other. This is a nice solution, but it
means that changes are propagated slowly, and syncing has historically
been very difficult in the programming world.

As my final thought, I've been thinking about what 37 signals does.
Their applications don't really interact at all. You have to login
separately to each one, data isn't shared between them, they are
basically separate products. In our situation we would like our
products to be more tightly intertwined than the 37 signals ones.
However, given that 37 signals doesn't do it, perhaps it's not
possible? It's not what rails was designed to do? It's a bad idea?

Anyway, what do all of you think? Do we just keep growing and growing
the main application? Do we force ourselves to create completely
separate products?

If we can somehow segment functionality into different rails
applications that still work together as a whole, what is the best way
to do it? Has anybody tried? Does anybody have any experience with
this? Please share any tools, plug-ins, or best practices that you
think could help.

Thanks a lot!

Just the first thing that springs to mind.

in your product class do

named_scope :green, ...
named_scope :recycled, ...

def self.scope_for_subdomain(subdomain)
  send case subdomain
  when 'green' then :green
  when 'recycled' then :recycled
  else
:all
  end
end

and then your index action is

Product.scope_for_subdomain(request.subdomains.first).find :all
You could also just use anonymous scopes

Depending on what's in your app it might be better to pull the
selecting of the scope out into a before filter.

Again a random thought: products have a base price, and you have a
price_overrides table (products has_many price_overrides etc...)
Assuming you have Store objects describing the stores and a filter
that sets the current store you could have a method in your product
class similar to

def overriden_price(store)
  override = price_overrides.find_by_store_id store
  override ? override.price : self.price
end

and when you want to display the price to a user you just do

product.overriden_price(@current_store)

[Rails] Views and bindings

[Joe Blow]

hello all, I was hoping someone could describe to me how this works.

Say I have some block of code like this

<% my_cool_block do %>
   <% my_var = 5 %>
   <%= some_helper_method "My var" %>
<% end %>

And in my helper

def my_cool_block(&block)
  content = capture(&block)
  concat(content, block.binding)
end

def some_helper_method(text)
  "#{text} = #{my_var}
end

How can i get some_helper_method to 'know' about my_var which is in the
scope of the my_cool_block block? And even better yet, how could I get
the some_helper_method only to work when it is nested inside a
my_cool_block block?

Let me know if I can clarify anything for you.

Thanks!

I am sure there's a few ways of doing this.  Here's an easy one:
declare a method in  the Country class and use that.

class Country
  

  def people_tribes
peoples.map{|p|p.tribes}.join(',')
  end
end

now in your view use country.people_tribes

[Rails] Ecommerce site w/multiple subdomains

[Wayne M]

My company is looking at redoing our legacy Classic ASP storefront,
and I'm thinking about doing it in Rails since the alternative is to
use a PHP-based solution called Magento that, while it looks nice, is
insanely abstract to the point of making me go blind (it uses a
database design principle called Entity-Attribute-Value or EAV which
basically is to keep database tables like hashmaps that can contain an
infinite number of values).

The principle requirement of this site is to be able to filter certain
products based on the subdomain, since we want to have different
"brands".  The products aren't specific to this subdomain, but the
subdomain only shows a subset of products.

For example:

www.mysite.com: displays all products with categories/subcategories
(i.e. no filtering)
furniture.mysite.com: displays only products/subcategories with a
parent category of furniture
green.mysite.com: displays only products/categories/subcategories with
a (boolean) flag recycled = true

How would I go about doing this?  The only way I can think would be to
have separate controllers for each "store", for example:

# Main store i.e. no subdomain
class StoreController < ApplicationController
  def index
@products = Products.find(:all)
  end
end

# furniture.mysite.com
class FurnitureStoreController < ApplicationController
  def index
@products = Products.find_all_by_category('Furniture')
  end
end

# green.mysite.com
class GreenStoreController < ApplicationController
  def index
@products = Products.find_all_by_recycled(true)
  end
end

But that seems rather unweildy.  This is a critical business
requirement since we want to create different stores with their own
unique look and feel, but the actual data displayed comes from one
master database and needs to be filtered appropriately based on the
store the user is browsing.

Another critical requirement we have is that each individual product
can have up to four prices, and the price is chosen based on the
"store" the user is viewing it on (e.g. Product A is $15.00 on the
mysite.com, but $12.00 on furniture.mysite.com).  I'm not sure what
the best way to tackle that problem would be.

Any assistance with either or both of these issues would be greatly
appreciated!

[Rails] rake test:units failing.

[Maulin Pathare]

Hello,
I am a rails beginner and am having some trouble running the unit tests
using rake. i am following the example in the simply rails 2 book.

I have a simple model with one field "name" and a validation for name
that it cannot be empty

my test file looks like this


   1. require 'test_helper'
   2.
   3. class LadderTest < ActiveSupport::TestCase
   4.
   5.   def test_create_ladder_name_error
   6. l = Ladder.create(:name => nil)
   7. assert l.error.on(:name)
   8.   end
   9.
  10. end

When I run rake test:units from the shell I get the following error

rake aborted!
You have a nil object when you didn't expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]

I am running rails version 2.2.2

Does anyone know whats wrong? Thanks.

[Rails] New to Rails... Help!

[Jay Mark]

I am new to Ruby/InstantRails. I am using InstantRails 2.0.2 with mysql
database

My application is named Area, it has two tables: people and country
Table people has two columns: name and tribe
Table country has two columns: location and population

In the models I have:
class People < ActiveRecord::Base
belongs_to :country
end
class Country < ActiveRecord::Base
   has_many :peoples
end

I have country_id in the people's table.

I know I can do this:
<% @peoples.each do |people| %>
<%= people.name %>
<%= people.country.location %> // This works

What I want to do is to display location on country\index.html.erb

<% @countries.each do |country| %>
<%= link_to country.location, :action => "show", :id => country.id
%>


Then when I click on 'location' as a link, I want to display the 'tribe'
along side with 'population' for that 'location' on
view\country\show.html

<%=h @country.population %>   // this works

<%=h @country.tribe %>   // this does not works

My question is, how can I reference a column from the people's table
with a country's object? I know it works the other round.

Please help!

[Rails] Re: Getting at DBI connection via ActiveRecord connection

[Wes Gamble]

Upon further inspection, I see that AR doesn't depend on DBI.  I wonder 
why not...

As it turns out, I'm in a JRuby environment, so I can just do prepared 
statements via that method.

Thanks,

Okay cool. Is there a better way to call gsub_file protected method

[Rails] localhost redirect/404

[Scott Peterson]

I think this is more of a windows question than rails per se, but I
can't see the answer.

I've just installed InstantRails 2.0 on my XP machine.  Both Apache and
mySQL start up fine.  I spark up the 'cookbook' app, and notice that
Mongrel starts it on port 3001, but other than that, pretty much the
same as my laptop (I think, I don't have access to that right now).

However, when I go to the browser, localhost:3001 directs to local:3001
and gives me the 404 page.

The only thing in my hosts file is a line for 127.0.0.1 going to
localhost, so it doesn't seem like that's the problem.

I've also tried port 3000, and hitting the server directly (127.0.0.1),
all result in 404.

Adding the mapping in hosts from 127.0.0.1 to 'www.mycookbook.com' per
the readme works great for the cookbook application, but I'd like to
just be able to hit locahost:3000 and run whatever application currently
is started for development.

Not sure where else to go from here.  Anyone got an idea what I'm
missing?

There's not a post-unzip setup step that I've forgotten for InstantRails
maybe?

[Rails] Getting at DBI connection via ActiveRecord connection

[Wes Gamble]

I have a standalone batch program that is going to move data between two
databases.

I am taking advantage of the AR connection semantics in database.yml to
get connections to these two DBs.  But I want to do all of my DB access
at the DBI/DBD level for performance reasons.

I am having trouble getting access to the underlying DBI handle so that
I can prepare SQL statements, execute them etc.

>From a connection retrieve via AR::Base.retrieve_connection, how can I
get at the DBI handle?

Is it possible that I've misunderstood that AR DB access is built on top
of DBI?

Thanks,
Wes

You would think so, but there doesn't seem to be.  `script/generate
resource` also adds routes, but looking at the source, they're doing
something similar:

def route_resources(*resources)
  resource_list = resources.map { |r| r.to_sym.inspect }.join(', ')
  sentinel = 'ActionController::Routing::Routes.draw do |map|'

  logger.route "map.resources #{resource_list}"
  unless options[:pretend]
gsub_file 'config/routes.rb',
/(#{Regexp.escape(sentinel)})/mi do |match|
  "#{match}\n  map.resources #{resource_list}\n"
end
  end
end

There is a :uniq option that will ignore duplicates:

  class Band < ActiveRecord::Base
has_and_belongs_to_many :users, :uniq => true
  end

This won't raise an error, but it will prevent duplicate associations.
 Hope that Helps

[Rails] Inserting to a View - Auto Incrementing Issue

[Paul Harv]

Hi,

My app has a model defined like this:

MyModel < ActiveRecord::Base
  set_table_name "SOME_LEGACY_VIEW"
  set_primary_key "LEGACY_ID"
end

The Database is DB2.
The view definition looks like this

SELECT
LEGACY_ID, NAME
FROM LEGACY_TABLE

When I create a new model and try to save it by doing this...

myModel = MyModel.new
myModel.name = "TEST"
myModel.save

Rails is creating an INSERT statement which includes the primary key -
LEGACY_ID - set to an ampty String. This blows up auto-increment on
LEGACY_TABLE.

Anyone seen this? Suggested solution.

Note - if LEGACY_ID is removed from the view it works OK, but I'm
working with requirements that say it should be there.

Thanks.

[Rails] Re: Sending mail templates to a mailinglist

[Dave Smith]

Hi Fred,

At present the recipient is a single email address coming from the 
emailer page (just to test the mailer works).

I have moved the sendmail form into the mailinglists index view page 
(and also moved the sendmail function from the emailer controller to the 
mailinglist controller) and it still works fine by sending the 
recipient, subject, message to the emailer model.

However I created a mailings scaffold which holds each of the email 
addresses, and names for the people on the mailinglist (with a one to 
many relationship).

So now I am stuck as I dont know how to create a button that sends an 
email to all the mailings in a mailinglist with the mailinglist_template 
associated with that mailinglist!!

Any help on this would be greatly appreciated!!

Kindest Regards,

Louis

You can use the scopt attribute of validates_uniqueness_of

users/bands has it's own model

in this model (BandsUsers)
validates_uniqueness_of :user_id, :scope => band_id

[Rails] Checking if an association already exists between two records

[Gearóid O'Ceallaigh]

Hey,

I'm creating an app which has two models - bands and users. A
relationship between users and bands in many to many.

However, when I'm adding an existing to user to a band (ie. updating
the bands_users table) how can i check if the relationship between the
user and the band already exists? For example, if a user with ID of 3
was already a member of a band with ID 5, and then somebody tried to
make this connection again - I want to output an error message. Is
there some special validation I can place in a bands_users.rb that
validated the uniqueness of the entire record?

Thanks,
  -ger

[Rails] Building a Root Route with a Generator

[Tim K.]

I'm looking for a better approach... then what I'm currently doing.

I'm working on a generator that will help me setup my base projects
with many of my common defaults that I use internally. Now I know that
generators have the route_resources method that allows a person to
create a resource in the routes file, but is there a way to create the
map.root :controller => 'name' entry as well?

Here is what I've done. I customized the route_resources method to be
something like this:

def add_root_route
  sentinel = 'ActionController::Routing::Routes.draw do |map|'
  gsub_file 'config/routes.rb', /(#{Regexp.escape(sentinel)})/mi
do |match|
"#{match}\n  map.root :controller => \"welcome\"\n"
  end
end

And then just copied the gsub_file method to my generator (it was a
protected method and I couldn't think of another way to execute it -
thoughts?).

I then have a bit that does:

  action = File.basename($0)
  case action
when "generate"
  add_root_route
when "destroy"
  puts
""
  puts "Make sure you remove the map.root from the /config/
routes.rb"
  puts
""
  end

Which makes sure it only runs when they are running generate.

My question is this... Is there an better way to be doing this? It
seems like a lot of insanity just to add a root route.

Thanks for your answer Fred..

I am in development environment, I have config.cache_classes =* false* (in

In the environment.rb file i have require File.join(File.dirname(*__FILE__*

I try  by instancing load_once_path: Dependencies.load_once_path?(RAILS_ROOT)
in my environment.rb
But does not work. I am not an ruby expert.

Can you explain me what can I do?

Well instead of doing

Emailer.deliver_contact(recipient, subject, message)

You could clearly do

recipients.each do |recipient|
   Emailer.deliver_contact(recipient, subject, message)
end

assuming that recipients was some collection of email addresses

Just look in development.log. It shows you what params are received.  
from that it should be clear.

[Rails] config.gem dependencies broken?

[Jörg Battermann]

Hello there,

I am having some strange problems with my project's gem dependencies
on my staging server and really don't know where this is coming from.

My config.gem entries in the environment.rb file are the following:

--- snip ---

  config.gem "geonames"
  config.gem "yelp"
  config.gem 'oauth', :version => ">= 0.2.1"
  config.gem "vikinggem", :lib => "viking"
  config.gem "RedCloth", :lib => "redcloth", :version => ">= 4.0"

  config.gem 'json'
  config.gem 'hpricot'
  config.gem 'uuidtools'

--- snip ---

Now when I do a gem list --local on the affected machine, it looks
like this:

First of all, why is it saying hoe/rubyforge is missing (as they are
listed in the gems list --local list) & secondly, why's there a
nil.dependencies exception?


Apparently this also does break my app, since all views that rely on
acts_as_textiled throw a "ActionView::TemplateError (uninitialized
constant Err::Acts::Textiled::ClassMethods::RedCloth) .." exception.


I already did a sudo gem uninstall/clean/install of all gems.. no
change :-/

[Rails] Functional Test - RJS Template not found

[Florian]

Hi Everyone,

i have the following Problem. For one of my controllers im using
a .js.rjs template for the create action. This works fine in
development and production mode. However, when i try to run a
functional test for this action, i get the following error:

ActionView::MissingTemplate: Missing template connectors/create.erb in
view path [...]/app/views:

Only if i explicitly use "render :template => 'connectors/
create.js.rjs'" the rjs template is found and the test runs through.
Do you have any idea why the template is not found and used without
this? Im now at Rails 2.2.2.

Thanks!

Florian

puts always appends a carriage return whereas write doesn't. if you  
changed it to STDOUT.write(line) it should be the same

You might try asking on the ruby list rather than here as it isn't

..good call on this one though, I added PRE tags on my index.rhtml and 
the data is looking the way I want it...which is great news.

I am still a bit baffled as to why I have to write the data to a file 
first, then open the file and put it in PRE tags as opposed to using 
PUTS statements in my original script and assigning that to a variable 
which gets called by my index page which still causes the format to be 
skewed.

my_data.rb code:
data.each do |line|
   a.write(line) #--this writes to my_data.dat
   puts line #--this puts the same data to STDOUT
end

def index
   @my_data = `/usr/bin/my_data.rb`   #this causes data to be skewed
   [EMAIL PROTECTED] = File.open("/usr/bin/my_data.dat").read #this works
end
---
index.rthml code:
<%= simple_format @my_data %>

Perhaps the way I'm writing to STDOUT in my_data.rb is causing the 
skewing of my data?

The old style include that did one big join would probably do that for
you.
Just to be sure  - I'm assuming that friendships and friends are a
self referential has many though relationship (ie back to users ?)

I'd write the above query like this:
u = User.find_by_username ...
u.friendships.find :all, :joins => :friends, :order =>
'last_activity_at desc'

You could squish that down to one query, but you'll have to work out
how it aliases the table names (I always have to look that one up)

Check again. I can assure you that resortclassid is not in params[:
resortclassid] but is somewhere else.
Don't flail around blindly, use the debugger to inspect the params
hash and you'll find out soon enough (or as a poor man's alternative
use
<%= debug(params)%> in the view to display all the parameters received

Hey Vipin, are you using the same application code for both Rails 2.0.2 and
2.2.2
execution of your tests.  If so, did you update the configuration files when
executing your application code against Rails 2.2.2?

Ohh I see, I was trying to sort friendships table, but there is no 
column last_activity_at. I guess that's it. :( or is there a way to 
re-sort the data by last_activity_at ? Cheers

[Rails] acts_as_versioned and rails 2.2.2

[Emuen]

Hi people I have tried to install the acts_as_versioned gem from
github in rails 2.2.2 but it seems to conflict with some methods in
the activerecords dirty.rb-file. I can solve some of the problem by
changing code in the activerecord, but I don't think that was the
intention.

That sort would have ordered the users (from the 'main' find) by  
descending last_activity_at, not the associations (which are loaded  
with a separate find)

[Rails] Can't restart memcached anymore

[Justus Ohlhaver]

Hi,

My memcached has been working perfectly.

But all of a sudden I am not able to restart it anymore
(RAILS_ENV=production rake memcached:start),

getting this error message:


failed to set rlimit for open files. Try running as root or requesting
smaller maxconns value.


This has never happened before.

Does anyone know where and how to request a 'smaller maxconns value'?

(Running root doesn't help me. It tells me 'can't run as root without
the -u switch'... not sure what that means. Running the sudo rake task
with '-u' shows no result at all..)

Thanks a lot for any help!
Justus

[Rails] find query

[Petr Bobek]

Hi,

I have user table (last_activity, last_activity_at, ) and
friendships table (many to many).
What I am trying to do is to show to the user the last actions of
his/her friends.

[EMAIL PROTECTED] = User.find_by_username(username, :order =>
'last_activity_at DESC', :include => [:friendships => :friend])[/code]

[code]<%= render :partial => 'friends_activity', :collection =>
@activities.friendships %>[/code]

But the descending ordering is not working :( What I am missing here?
Cheers, Pete
