It uses a method called 'build', which says (to me at least) that it doesn't
exist.

[Rails] Re: is Rack right for this?

2011-07-11 Thread BryanD

I've been using Sinatra for API stuff lately and love it. In
particular I've been getting great results with async Sinatra via Kyle
Drake's Sammy Davis Junior boilerplate.  I'm on a mobile device now,
otherwise I'd give you a link.

You could just write your own rack app, but that's probably not
necessary.

Another thing to check out is Goliath.

[Rails] is Rack right for this?

2011-07-11 Thread Bill Walton

Greetings,

My 2.3.2 app has 2 components.  It serves a browser-based client, and
it serves a web service client.  Each client has its own set of
controllers to separate authentication / authorization cleanly and
clearly.  The web service client sends gets, posts, and puts, some
with xml bodies, and the app responds with status / location and xml
bodies where appropriate.  I'm in the beginning stages of moving the
app to Rails 3.  One thing I'd like to accomplish is to reduce the
start-up overhead associated with the web service requests if
possible.  I really don't need / use the erb functionality in
constructing the responses, for example.  The thing I don't have my
arms around at this point is how to get the controller and model
'stuff' loaded without the bulk of the view 'stuff'.'  Anybody got any
experience / insight to share.  I don't seem to have my google fu in
order.

Thanks,
Bill

[Rails] Date Parsing Puzzlement

2011-07-11 Thread Leigh Daniels

Hi All,

When I enter a Start Date in the text field as "07/11/2011" it gets stored in 
the database as "2011-11-07" instead of "2011-07-11".

This change happens before the column is available in the controller. Is there 
some Rails setting that will make this happen magically or do I have to have 
some fun with date parsing?

Thanks!

**Leigh

-

[_form.html.erb]
<%= f.label :start_date, :class => 'label'  %>
<%= f.text_field :start_date, :size => 15 %>

[jobs_controller.rb]

@job = Job.new
@job.rate = 125

respond_to do |format|
  format.html # new.html.erb
  format.json { render json: @job }

I watched the screencast, and it covers the multi step form thing but
with only one model.
I'd like to the the same thing but each step would be a different
model. How can I do that?

Exactly -- if they're not *identical* they're not "duplicates".

On the other hand if you define "similarity" to some degree you can use
e.g. the Levenshtein gem to measure how "different" 2 given fields are.

[Rails] Re: Duplicate Record Detection

2011-07-11 Thread pepe

Whenever I have worked on similar projects in ended up being the
customer's idea of what a "close approximation" was that made a
possible duplicate. It was usually something like:
  same birth date
  same last name
  same city (optional)
  same state (optional)

Since there is not such a thing as a tried and true method for what a
duplicate record is I believe you'll just need to do some manual work.
My advise would be to ask your customer/boss for what the rules are.

Re: [Rails] Re: Duplicate Record Detection

Yes, this is all very true. I was thinking if a comparison was done on
multiple attributes that would help with just one name being wrong. I'm not
looking for magic, just wondering how others find duplicated records. I
could see this being used to detect data that links or is similar in nature.

Found this as well.

Re: [Rails] Re: Duplicate Record Detection

It would stop duplication of that unique string, but not fix a typo like
transposed numbers. Besides, that was a simple example, not meant to be
challenged. It's the process of detecting duplicates, I'm looking for. I
know how to validate and key tables. Maybe another example is loading a
million records from external source, and you need to find duplicates. I'm
just asking if anyone has seen api's or ruby utilities that preform this
function. Like SimString it seems to compare how close to strings are to
matching.

[Rails] Re: Duplicate Record Detection

2011-07-11 Thread pepe

I don't believe you're going to find a magic formula for what you're
suggesting. The same thing could be said about last or first names as
you are suggesting could happen with SSNs. What if somebody misspells
Smith for Smit, for example? But worse yet, what if it is not a
misspelling situation and the Smit is actually Smit? The same is true
for SSNs, switching the last 2 digits does not mean it was a
"misspell", it could just be that 2 different people have the same
name and very similar SSNs. You have to draw a line somewhere, I
think.

You could use auto-complete fields and then provide options based on
records found using the 'LIKE' option in the where clause using the
information currently being entered. That might help but I think
you'll find it's not worth the effort.

"slow the duplication"?? No, insuring that the SSNs *are unique* via
validations and unique indexes would prevent duplicates, period.

Re: [Rails] Help filling out a registration (I think it's called multi tenant)

2011-07-11 Thread Walter Lee Davis

And just FYI, multi-tenant usually means that you have one database
containing separate (unrelated) client accounts, for example Basecamp.
There isn't a separate database for my Basecamp account and yours, our
records are all commingled in one set of tables, and the server
enforces business rules to make sure I don't see your messages and
vice-versa.

I'd like to do that, but I have no idea how.

Basically I have a company model with its information, and a
contacts model, with belongs to my company (also each company has
only one contact), and I'd like for the user to fill in the company
specific information (like email, name, address, etc), and click
next down the page to fill in the contact information (telephone,

[Rails] Re: Preventing serialization of attributes in the model

2011-07-11 Thread jhaagmans

Hi Peter,

Your suggestion will work fine. Thank you. I was hoping there would be
a way to do this within ActiveModel or ActiveRecord because I also
want to do this the other way around: I would like to render some
javascript in which can dynamically define these attributes. I'll have
to do that with some kind of model variable or method.

The test claims to be failing because the languages table does not have a

http://stackoverflow.com/questions/5914736/rails-3-undefined-method-model-name-for-arrayclass
 .

I decided to change my ../ballot/new controller to:

def new
@survey = Survey.find(params[:survey_id])

@ballot = @survey.ballots.build

# Prepare the ballot
@ballot.preferences = @survey.questions.map{|question| 
question.preferences.build}
#for question in @ballot.survey.questions
#  p = Preference.new
#  p.ballot = @ballot
#  p.question = question
#  @ballot.preferences << p
#end

respond_to do |format|
  format.html # new.html.erb
  format.xml  { render :xml => @ballot }
end
  end

And the new view to:

<%= form_for [@survey, @ballot] do |f| %>
  <%=h @ballot.preferences[0].question.inspect %>

  <%= f.fields_for @ballot.preferences do |preference_form| %>
<%= preference_form.fields_for :question do |question_form| %>
  
<%= question_form.label :question %>
<%= radio_button("preference", "preference", "Yes") %> Yes
<%= radio_button("preference", "preference", "No") %> No
<%= radio_button("preference", "preference", "Decline") %> Decline
  
<% end %>
  <% end %>

  
<%= f.submit "Vote" %>
  
<% end %>

And now I receive the error:
undefined method `model_name' for Array:Class

for the fields_for line.

My guess is @ballot.preferences isn't a proper set of instances but just an 
array, though my Ruby on Rails skills aren't good enough to figure this out. 
Any ideas?

[Rails] stuck with permissions in using FileUtils

2011-07-11 Thread Erwin

Even if I am using PaperClip & Delayed_job, I guess the issue maybe
solved by FileUtisl gurus ...

here is the case :

I am testing a delayed video format transcoding , transcoding works
perfectly but I get an issue -trying to write back the transcoded
video from a tmp directory into the PaperClip path

the original uploaded video file is stored into the   :url => "/system/
clips/:data/65/original/swing.avi",

in the delayed_job, I get  the clip :
   clip = Clip.find(65)
  @clip_file = clip.data.path #   =>  ( ".. rails/myapp/public/
system/clips/data/65/original/NickFaldo.avi" )
  @clip_dir = File.dirname(@clip_file) #  =>  (".. /ls/myapp/
public/system/clips/data/65/original" )
  basename = File.basename(@clip_file, File.extname(@clip_file))
# => NickFaldo

the ffmpeg transcoding process, is writing an output file into the tmp
dir , without any problem
  @tmp_dir = FileUtils.mkdir_p(Rails.root.join("tmp", "converted",
"#{clip[:id]}"))#   =>  ( "../clips/tmp/65i" )
  @tmp_file = File.join(@tmp_dir, "#{basename}.mp4")#  =>
( "../clips/tmp/65/NickFaldo.mp4" )

until then everything works as expected ...

then I want to bring back the transcoded clip in place of the original
one ... with the same base name but with an .mp4 extension
  @converted_file = File.join(File.dirname(@clip_file),
"#{basename}.mp4" )  #   =>  ( ".. rails/myapp/public/system/clips/
data/65/original/NickFaldo.mp4" )

so I wrote :
FileUtils.rm @clip_file  # remove clip_file# to remove
the previous original
FileUtils.chmod(0777, @clip_dir )
FileUtils.cp @tmp_file, @converted_file  #  copy
transcoded file as  new  original
FileUtils.rm_r @tmp_dir #
remove tmp directory

but I get anexception raised
( not being root I believe I can't change the permissions and write
into the PaperClip path for this clip 

any suggestion will be welcome ... thanks

[Rails] Help filling out a registration (I think it's called multi tenant)

Do you know when you are filling out a registration for a new account, and
you keep pressing next to fill the rest of the information in separate
pages?

I'd like to do that, but I have no idea how.

Basically I have a company model with its information, and a contacts model,
with belongs to my company (also each company has only one contact), and I'd
like for the user to fill in the company specific information (like email,
name, address, etc), and click next down the page to fill in the contact
information (telephone, manager email, etc). Also I'd like to save it to the
database only if all the information in both pages are inputed.

Thank you,
Rodrigo

[Rails] when iterating tables with ActiveRecord::Base.connection, how do you check if a string is equal to the current table iteration?

2011-07-11 Thread John Merlino

Hey all,

This here is not working:

 task(:load_selected => :load_config) do
   IgnoreTables = %w('students')
  begin
   ActiveRecord::Base.establish_connection
   ActiveRecord::Base.connection.tables.each do |table|
  if IgnoreTables.include? table
puts "Its true"
next
  else
ActiveRecord::Base.connection.execute("TRUNCATE #{table}")
  end
 
end
   end
 end

Despite that some point table will be equal to students and students
is in the IgnoreTables array, it should skip to the next iteration,
but rather the else is triggered and the table is truncated.

Anyway know how to address this? Is there a method part of connection
that will help me achieve what I am trying to do?

Thanks for response

Re: [Rails] Re: Duplicate Record Detection

That would help slow the duplication, but if someone fills out a form and
submits fname, lname, ss#, and they typo the ss# I would have a duplicate. I
would like to display to admin users that this record has a related link, or
is similar. Similar to how Google finds duplicates in your contacts and
merges them.

It might help us if you showed us the failing test.  Also I think it
would be better to use name_id as the foreign key for language
belongs_to :name.

In this test, I have a before block setup as such:

[code]
  before do
setup_controller_for_warden
controller.session[:operation_id] = 1
@operator = Factory :operator
sign_in :operator, @operator

@persist_herd = Herd.new
@persist_herd.operation_id = 1;
@persist_herd.herd_name = 'Persisted Herd
(herd_rations_controller_spec)'
@persist_herd.save!
  end

  describe "GET new" do
it "assigns a new herd_ration as @herd_ration" do
  HerdRation.stub(:new){ mock_herd_ration }
  Herd.stub(:find).with(1) { @persistant_herd }
  
  get :new, :herd_id => 1
  assigns(:herd_ration).should be(mock_herd_ration)
  response.should be_success
end
  end


and here's my controller method:

  def new
@herd_ration = HerdRation.new
@herd = Herd.find(params[:herd_id])

if @herd
  respond_with(@herd_rations, :layout=> !request.xhr?)
else
  redirect_to(root_url, :notice => 'No herd selected for ration.')
end
  end
[/code]

Here's the catch - we have this groovy little plugin that globally enforces
a model scope via a session id, in this case: session[:operation_id].

Here's the code for the plugin:

[code]
module ApplicationScopeManager


   mattr_accessor :global_scope
   @@global_scope = []

   mattr_accessor :local_scope
   @@local_scope = {}

   def self.included(base)
  base.send :extend, ClassMethods
   end

   def self.setup
  yield self
   end

   module ClassMethods


  def method_missing(name, *args, &block)

 return acts_as_scope_manager($1, args) if name.to_s =~
/^acts_as_scope_manager_for_(.*)/
 
 return honors_scope_of($1, args) if name.to_s =~
/^honors_scope_of_(.*)/
 
 return current_scope_for($1) if name.to_s =~
/^current_scope_for_(.*)/
 
 super
  end

  def current_scope_for(scope)
 Thread.current[scope.to_sym]
  end

  def acts_as_scope_manager(scope, *args)
 options = args[0].extract_options! if args
 send :include, InstanceMethods

 set_global_scope(scope,options[:with_global_scope]) if
options[:with_global_scope]

 send :before_filter, "set_scope_for_#{scope}".to_sym if
self.ancestors.include? ActionController::Base
 send :default_scope, where(scope.to_sym =>
send("current_scope_for_#{scope}".to_sym)[:finder_scope]).create_with(scope.to_sym
=>
 send("current_scope_for_#{scope}".to_sym)[:creator_scope]) if
(self.ancestors.include? ActiveRecord::Base) && Thread.current[scope.to_sym]
  end

  alias honors_scope_of acts_as_scope_manager

  private


  def set_global_scope(scope, *args)
 Thread.current[scope.to_sym] = {:global_scope => args}
  end

   end

   module InstanceMethods

  def method_missing(name, *args, &block)

 return set_scope_for($1, args) if name.to_s =~
/^set_scope_for_(.*)/

 super
  end

  private

  def set_scope_for(scope, *args)
 if session[scope].class == Array
application_scope = {:finder_scope => session[scope],
:creator_scope => nil }
 else
application_scope = {:finder_scope => [session[scope]],
:creator_scope => session[scope] }
 end

 application_scope[:finder_scope] = application_scope[:finder_scope]
+ Thread.current[scope.to_sym][:global_scope] if
Thread.current[scope.to_sym][:global_scope]

 Thread.current[scope.to_sym] = application_scope

  end

   end
end

[/code]

This plugin enforces any model that calls the honors_scope_of_operation_id
to include a lookup of the session[:operation_id] in all database calls.  
For instance if I do a Model.find(params[:id])  it will automatically add a
WHERE "field_name"."operation_id" = to the where clause.The problem I'm
having is that I can't seem to mock the session[:operation_id] in my Rspec
tests.I thought setting it this way  controller.session[:operation_id] =
1 in the before block would have been sufficient.

Any ideas?

[Rails] [ANN] Zena 1.1.0 + dreamhost

2011-07-11 Thread Gaspard Bucher

Hi there !

If you want to test Zena between to rounds of beach volley, wave jumping,
ice climbing or whatever you do when not sitting in front of a screen, I
fixed many annoying bugs in the 1.0 release and created a brick to ease
deployment on shared hosting. There is even a small manual to deploy on
dreamhost:

http://bit.ly/oqoZ5i

Have fun

Zena is a CMS based on Rails that lets you rapidly create complex
applications (without ever restarting the server). The main features are:

* data modeling (virtual classes, properties, indexing, relations)
* multilingual, versioned, publication workflow
* access control lists (different/limited access for a client for example)
* secured access to every element based on groups (like unix does)
* image handling, full page caching, pdf generation, csv, etc.

[Rails] Pre-populating association

2011-07-11 Thread Christopher Thielen

Hello,

I think this is an easy one for the average Rails developer but I'm a bit stuck.

I'm creating a simple voting app: any user can create a survey, with any number 
of questions, and other users can then vote by creating a ballot for that 
survey.

Here's the modeling:

class Survey < ActiveRecord::Base
  has_many :questions
  has_many :eligibilities
  has_many :ballots

  accepts_nested_attributes_for :questions, :allow_destroy => true
  
  attr_accessible :title, :description, :status, :deadline, 
:questions_attributes
  
  def owner
Person.find(owner_id)
  end
end

class Question < ActiveRecord::Base
  belongs_to :survey
  has_many :preferences
end

class Ballot < ActiveRecord::Base
  belongs_to :survey
  has_many :preferences
end

class Preference < ActiveRecord::Base
  belongs_to :ballot
  belongs_to :question
end

To be clear: a survey is the set of questions and a ballot is a voter's set of 
answers (preferences).

I'm using the nested route: /surveys/[:survey_id]/ballot/new for the voting 
page.

What I'm having trouble with is pre-populating the ballot with empty 
preferences. When ballot/new is called, I do this:

def new
@survey = Survey.find(params[:survey_id])

@ballot = @survey.ballots.build

# Prepare the ballot
for question in @ballot.survey.questions
  p = Preference.new
  p.ballot = @ballot
  p.question = question
  @ballot.preferences << p
end

respond_to do |format|
  format.html # new.html.erb
  format.xml  { render :xml => @ballot }
end
  end

and on the ballot/new.html.erb page, I try this:

<%= form_for [@survey, @ballot] do |f| %>
  <%= f.fields_for :preferences do |preference_form| %>
<%= preference_form.fields_for :question do |question_form| %>
  
<%= question_form.label :question %>
<%= radio_button("preference", "preference", "Yes") %> Yes
<%= radio_button("preference", "preference", "No") %> No
<%= radio_button("preference", "preference", "Decline") %> Decline
  
<% end %>
  <% end %>

  
<%= f.submit "Vote" %>
  
<% end %>

But this merely shows one set of radio buttons with no question text, though 
I've confirmed the @survey.questions are populated with questions.

Does anybody see what I'm doing wrong here? My guess is looking at the 
new.html.erb is going to really show off something incorrect.

In addition to other replies note that logic in controllers should
rarely be sufficiently complex so as to require helpers.  Such code
should almost always be in the models.

Hi,

follow the steps from my Github repo 
https://github.com/gezope/InstallingRailsOnUbuntu
and get me back if you still have problems. Important: if you're usig
RVM (you definitely should) then don't use 'sudo' for install. First I
think just use SQLite3.

Dheeraj is correct, helpers are intended for views, but if you have a
method that you need access to in your controller and your view, and/
or your helper then, in order to keep things a little DRYer, you can
define your method in your controller, and make it available to the
view and helper as so:

class MyController < ApplicationController

  helper_method :my_method

  private

def my_method
  # do something
end

end

Now you can access my_method from your view or your helper as well as
your controller.

Helpers help generate code for the view. For example, if you have an array
of items that need to be rendered in a specific way, you can encapsulate
that functionality in a helper method, and call it from the view. It helps
clean up the view code, and adds code reuse. So helpers are meant to be for
views, not controllers.
