[Rails] permissions and authorization

[Mike C]

In my app I have 3 different models in a linear fashion:

M1, M2, and M3. M1 has many M2 which has many M3.

M1 has 2 properties: private and completed. If it's private then only
the person who created M1 can do anything with it (all the rest
actions), and if it's completed then more M2 and M3 cannot be added.

For M2, only the M1 creator and the M2 creater (the M2 creator is most
likely a different person) can do anything with it (rest actions), and
the same goes for M3 except the people who can do anything with M3 are
the owners of M1, M2, and M3.

It seems these permissions are really complex and I'm not sure how I
should go about this. Before I just had protected methods in each of
the controllers of these models, but theres a lot of repeated code and
its just not pretty to look at. Should I abstract some of this into
the ApplicationController, or create a module/helper for this?

[Rails] ActiveRecord::StatementInvalid

[Tom Mac]

Hi
   I am using rails2.2.2 with mysql5.1. I have a text field 'EmailBody'.
And when I try to store data more than 65536  (Say for example 65550) in
linux it works properly by truncating it to 65536 characters and save
successfully to table.  But when I test this same application on a
windows machine I get the error ActiveRecord::StatementInvalid. I am
attaching the error I am getting on a windows machine. Is it a adapter
prblem. Please help

Thanks in advance

You can use Flying Saucer Library.Which convert XHTML to PDF.

[Rails] Re: RoR Tutorial : clear password field

The question comes from http://railstutorial.org/chapters/sign-up#sec:signup_exercises";>railstutorial.org.

The exercise in question:
Oftentimes signup forms will clear the password field for failed 
submissions, as shown in Figure 8.12. Modify the Users controller create 
action to replicate this behavior. Hint: Reset @user.password.

The solution: SPOLIERS!
In your user controller you defined 'create'.  If the save is 
successful(if @user.save) nothing needs to be changed.  If the save is 
unsuccessful(the 'else' condition in your code) we render new again with 
error messages.  You must reset @user.password before rendering the 
'new' page by setting it to nil.


  def create
@user = User.new(params[:user])
if @user.save
  flash[:success] = "Welcome to the Sample App!"
  redirect_to @user
else
  @title = "Sign up"
  @user.password = nil
  @user.password_confirmation = nil
  render 'new'
end
  end

Note: this code will not work if its placed after render 'new'.  It also 
will not work if you place it in 'def new' because you aren't calling 
that method, which is also why you have to set @title = "Sign up" again.

Hope that helps,

[Rails] injecting minitest/spec into IntegrationTest?

Hello,

I want to use the minitest/spec DSL inside an
ActionDispatch::IntegrationTest but I'm getting no-method errors:

# cat test/integration/wacky_integration_test.rb
#-
require 'test_helper'
require 'minitest/spec'

class WackyIntegrationTest < ActionDispatch::IntegrationTest

  end

  describe 'test' do
it 'should be wacky' do
  (2 + 2).must_equal 4
end
  end
end

Well, count() is just counting rows... it has to be an integer.  SUM() might be 
counting other things (decimals say) so maybe AR can't decide.

Still, it should be able to do it..

What's the SQL being generated?

Any difference if instead of joins() you includes() ?

 Quantity isn't on the model actually being queried so this doesn't
 surprise me. It does suck though. It looks like the sqlite3 driver is
 just smarter about asking the db for the types of the columns (I think
 that with sqlite3 you sort of don't have a choice the way the api is
 written, whereas with mysql you get all the columns as strings "for
 free". I could be wrong though. I don't know what the postgres api is
 like at all).

[IAmNan]

One other thing... the SQL generated by AR returns the correct column
types if pasted in the pgsql shell or in pgAdmin.

[Rails] Re: PostgreSQL aggregate function inconsistent (returns strings)

[IAmNan]

You're not too late and I appreciate your feedback.

But it gives the same stringified results. So, I don't think AR is
tries to interpret the types at all. It always thought it did in order
to provide a consistent interface. The fact that count works as
expected confuses me though. I'd think count and sum would behave
identically (except for the result, obviously).

I'm coming into this way late, but what happens if you...

sum('sales.quantity')

Would that give AR enough of a hint to figure out what table/type to cast it to?

Can you post the actual SQL being generated?  I didn't see it in the archives...

 In general AR doesn't know the type of non column expressions.
 If you did something like Product..group(:product_id).sum(:quantity)
 then AR knows you're doing a sum, and it knows that the sum of
 decimals should be decimals so it would cast what it got back from the
 db to the appropriate type

[Rails] Re: PostgreSQL aggregate function inconsistent (returns strings)

[IAmNan]

Okay, I understand what you are saying about :quantity not being on
the Order table. (Interesting, though... I just tried replacing "sum"
with "count" and guess what: numeric values come back.)

So two possible solutions: use ruby (in the model) to "fix" the hash
after the query, or use hardcoded SQL that explicitly declares the
return type instead of letting AR construct the SQL. Sounds about
right?

Quantity isn't on the model actually being queried so this doesn't
surprise me. It does suck though. It looks like the sqlite3 driver is
just smarter about asking the db for the types of the columns (I think
that with sqlite3 you sort of don't have a choice the way the api is
written, whereas with mysql you get all the columns as strings "for
free". I could be wrong though. I don't know what the postgres api is

I use Prawn, and might try WickedPDF at some point.  Correct me if I'm

With Rails, sometimes using a DB is the simplest thing, and it's 
actually harder not to do so.  But I agree with the sentiment.

If the OP only needs the *country* identified, GeoIP on the server is
the easiest solution.

For any finer granularity, GeoIP (or any IP-based system) is not very
reliable. (At the moment I'm in a moving vehicle south of Pismo Beach
California, and GeoIP thinks I'm in Manteca -- *way* off.)

But the client-side solutions are still a work in progress too, AFAICT  :-)

Your code just looks wrong to me - you're iterating over an array of
hashes, so client is a hash. Hashes don't have a name method so
client.name blows up. Did you mean client[:name]  or intend to use
that data to create an active record object first?

[Rails] Encoding error when trying to write file

I have to get email attachments ( mp4 files ) and store them...
I get easily all parts using Mail  (   )

attachment  = mail.attachments[0]
#, ,   >
got what I need,

but trying to store this attachment in a temp file , I get an encoding
error :

 File.open(filepath,File::CREAT|File::TRUNC|File::WRONLY,0644) { |
f| f.write(attachment.body) }

   Encoding::UndefinedConversionError Exception: "\x80" from

did I miss anything before writing the file ? or is it a known Ruby
bug ?
being an .mp4 attachment, it should be a binary file.. it comes as an
UTF-8 ( Base64) ? , right...
how should I write it as a binary too ?

Re: [Rails] Re: refactoring models

[Peter Bell]

It probably is, but why were you putting the data into a database? If there's a 
valid reason to do that, do it and then fix db performance with caching if it 
becomes a limiting factor.

If there's not a valid reason to put the data into a database, why would you do 
so? Start with the simplest thing that would possibly work to get your tests 
passing and go from there.

There was some discourse on one of the agile-like lists (maybe the XP list) 
recently with some people suggesting you shouldn't actually add support for a 
db to an app until you have the first test that won't pass simply by using in 
memory representations. That's a little extreme for me, but certainly I 
wouldn't put stuff into a db unless there was a good reason. And if there is a 
good reason for it being there, I wouldn't remove it for performance reasons 
until I had failing performance tests and profiling that pointed to that query 
as being part of my problem.

[Rails] Re: (JOB) Ruby on Rails Developers- Strongmail , Redwood Shores, CA

[dkerins]

The University of Victoria (Fine Arts Faculty) had a donation from Sun
of their workstations back in 1992-3 and I was hired as a junior
admin.  Around 1993-4, part of my job was creating web pages on SunOS
with HoTMetaL as an html editor and using NCSA Mosaic as the browser
and the CERN httpd daemon.  As cool as that was, I was totally blown
away by playing netrek on the server at Carnegie Mellon University
with people all over the continent.

In retrospect, it was pretty cool to have stumbled upon the early web
as a naive young student.  Since them, the changes and the speed of
change is awe inspiring.

[Rails] undefined method 'xxx' for {}:Hash rake db:migrate

[Billy]

Hi

I just installed rails 3 (3.0.3) and am trying to create a rake task.
I am seeing this:

rake aborted!
undefined method `name' for #

my rake task (simplified) is as follows:

namespace :app do
  desc 'Create dummy data'
  task :setup => :environment do
[
  { :name => 'Test User',   :email => 't...@xxx.com' },
].each do |client|
  puts '-'
  puts client.name
end
  end
end

Its barfing on that puts client.name

This appears to be an older bug.  The solution hinted at here

http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/d3e6af81dcbcce31/fded05c2c519a31f?lnk=gst&q=rake+aborted!+undefined+method+`name'+for+%23%3CHash#fded05c2c519a31f

is not working for me as rails 3 has a strong dependency on rake
0.8.7.

Anyone else seeing this problem?

A key fact missing previously was that you have a very small table and
could just hard code the data.
The answer is who cares?  Don't worry about it unless you have
performance or resource problems, in which case profile the code to
find out where the problem lies and then address it.  I can virtually
guarantee that the bottlenecks or resource hogs will not be in the
areas you might anticipate beforehand.

Re: [Rails] Re: refactoring models

[Peter Bell]

Just to be clear, what specific performance tests are you having a problem 
with? 

Refactoring for better readability/maintainability every time your tests are 
green is a good practice. 

Trying to make micro-optimizations in memory profile, sql queries, caching, etc 
without a specific failing performance test and profiling results showing which 
query or page load is causing the problem just burns time and obfuscates your 
code. Apart from anything else, the things that make your app slow are probably 
not those that you expect it to be.

The only thing I would say is that if you have a transient object that doesn't 
require persistence (I have a location object in a new app - I don't store 
locations - I just use them to handle geocoding and to return a list of places 
from a third party service) from what I understand (I'm still new to best Rails 
practices), it's quite reasonable to put that in the lib directory. I wouldn't 
wrap an entire AR lifecycle around a Class that I did not plan to persist the 
instances of. But that's not to improve performance (although it might in some 
way) but because it seems more semantically accurate - it better expresses my 
intent.

Best Wishes,
Peter

not sure what else to say.  If you have a db table with 2 lines that are 
never going to change.  You refactor that into the other model that 
references it and remove the original AR model.  I was wondering, when you 
remove the table if you were to keep the original model but refactor the

Not necessarily.  In terms of resources just loading models I would
think it is more down to lines of code than number of models.

Jeffrey,

Certainly another option but I would prefer not to have "network
config" logic in my application if I can help it.  If you want to
manage all of the housekeeping jobs from a remote curl or put in load
balancers you would need to change code.  I prefer to protect
resources like this in my httpd.conf that defines the server and
network environment.

[Rails] Re: PostgreSQL aggregate function inconsistent (returns strings)

[IAmNan]

As always, Fred, thanks for your reply.

The example you give works until you include a join, then you get
strings again.

Order.joins(:sales).group(:product_id).sum(:quantity)

That returns strings again. I don't think I did anything AR shouldn't
be aware of. BTW, the product_id is returned as a string too. I've
verified that SQLite3 returns numbers for both. This really seems
broken to me.

Order has_many :sales
Sale belongs_to :order
Order has a ordered_at datetime and the seller_id, Sale has the
product_id and quantity. This is why I need the join. (Oh, and Sale is
actually LineItem/line_item, although I doubt that makes a
difference.)

Are you asking whether a class derived from ActiveRecord::Base uses
more resources than one not so derived, apart from the resources used
by ActiveRecord::Base?  Sorry that seems to me to be not a useful
question to ask.  As I said previously if you could give some
background as to why you are asking the question it may make more

Could it be this?

It is ancient and I can't say I understand it, but the log looks very
like yours.

Otherwise I have reached the end of my knowledge span I think.

You do have the "responders" gem installed, in your Gemfile, and setup in

Thks for ur concern Colin. I even created a simple-mini app just using
the standard Rails Scaffold, in order to isolate the problem. And it
still remains. The main difference is that, in FF it passes (besides the
necessary parameteres) the "authenticity_token" and the "commit".

PS: I had to turn off protect_from_forgery in the
application_controller.rb in order to get it working in IE. Or else i'd
get a "invalid authenticity token".

If you don't provide a redirect_to, it will assume a view with
name create.html.erb or create.html.haml, etc. and try to render
it giving you a missing template.  The most common design is
create redirects to @model and destroy redirects to index_path.


If I put in create respond_with, for example respond_with(@sector) it 
seems that redirects automatically to show while respond_with(@sector) 
in destroy redirects to index.

How can it know where redirect?

Yes, you can omit respond_with. Most of my apps are entirely
without respond_with calls unless I have an explicit need for xml,
etc.


If I omit respond_with in some actions like create and destroy raise 
an error of missing template.

I'm not so sure. It depends on the use case, IMHO.

For example. Say you have http://www.mysite.com/ which needs to redirect the 
visitor to http://www.mysite.co.uk/ if the originating IP resolves to the UK. 
Using your method, a page would need to load, determine the geographical 
location and then use meta refresh or a Javascript in order to perform the 
actual redirect.

Using GeoIP on the server side, a redirect_to in the controller could take care 
of it all in one quick action.

But again, it all depends on what you need to do. If it's a matter of simply 
varying some sort of UI element, the client side way makes sense.

Your mileage may vary  :)

Do you wrap some security on those routes at the web-server level or

Well, of course Rails should *deal with* the data once acquired.  But 
acquiring the user's location is a job for the client side, isn't it?

[Rails] multiple fields_for on has_many relationship?

[Michael Mike]

I have a form for an ordered_special. An ordered_special has many
ordered_special_foods. Basically, within a loop in the form I am doing
something like the following:

<% special.foods.each do |food| -%>
<% fields_for OrderedSpecialFood.new do |os| %>
<% food.food_types.each do |food_type| -%>
<%= os.radio_button :food_type, food_type.id %> <%=
food_type.name %>
<% end -%>
<% end -%>
<% end -%>


So, I am trying to add OrderedSpecialFoods to the OrderedSpecial. The
problem is that I want the radio button to distinguish that we are
handling a different OrderedSpecialFood for each occurrence of the outer
loop. Right now, all of the radio buttons belong to the same group. I
understand why that is, but I want to distinguish between multiple new
OrderedSpecialFoods and I am not sure how to do that exactly. Any help
is appreciated.

I've seen in http://blog.plataformatec.com.br/tag/respond_with/

it says:

def create
@post = Post.new(params[:post])
flash[:notice] = "Post was successfully created" if @post.save
respond_with(@post)
  end

Can now be written as:

  def create
@post = Post.new(params[:post])
@post.save
respond_with(@post)
  end

Your locale just needs to have the following configuration:
  flash:
actions:
  create:
notice: "{resource_name} was successfully created"
  update:
notice: "{resource_name} was successfully updated"
  destroy:
notice: "{resource_name} was successfully destroyed"
alert: "{resource_name} could not be destroyed"

there is no notice definition in action create.

You may be correct in this statement, but there's also the option of segmenting 
the content on the server side. I.e., in Rails. It can arguably also be a nice 
attribute to have on a user model for future send-outs or similar.

Have a look at https://github.com/cjheath/geoip. Then check out 
http://www.maxmind.com/app/ip-location.

Could be but then again I don't look too closely at ads that don't
mention location so it could be seen as self defeating. Cryptic and
incompetent look much the same :)

But then why mention 'NFL athlete' in the subject line, is it meant to
pique our interest? Not sure I want to work somewhere where the
founder is a jock.

Tell me about the location, the offices, the local bagel shops, the pay.

I genuinely want to know why they included WAP and X-Windows. In an
interview I would judge the company on the answer they gave to such a
question.

[Rails] [ANN] TrackHistory: An easy way to track changes

[John Crepezzi]

Hey guys,

I made a gem for tracking changes on specific fields in ActiveRecord
models.
Its very easy to get started using, and automatically creates models
and
associations to history objects which contain the changes made.

If you have a table like:
users: (id, email, created_at)

And you'd like to track all of the changes the email has been through
over
time, in your model you'd just write:

class User < ActiveRecord::Base
  track_history
end

and create a table in a migration like:
user_histories: (id, user_id, email_before, email_after, created_at)

Automatically when you start up your server, user instances will have
#histories (an array of UserHistory objects) and UserHistory will have
some
convenience methods which you can read more about in the README.

You can also add annotations like:

class User < ActiveRecord::Base
  track_history do
annotate(:day_of_week) { Time.zone.now.wday }
  end
end

And the value of the annotation will be saved whenever the object is
updated.

There's are a bunch of other options to check out and configure,
such as the ability to track creates and deletes cleanly.

Check it out!

Yeah that really is an acronym soup he has there. I suspect that they

All three? And along with some of the other network stuff, considering getting

Really? Unless you have a really unique app, this is commodity. You don't want

The only reason for someone to know SOAP on this list is (a) so they can 
connect with painful legacy systems (I get that could be possible in retail for 
inventory) or (b) so they can be thankful they use RESTful web services and 
don't have to deal with that stuff any more. If you want to complete the usual 
annoying acronym soup, you missed XML. On a separate note, if you can find a 
programmer who can't figure out json, run very quickly in the other direction.

1) Modified spec_helper file
2) Added "-drb" to new line in .rspec file

If you're passing parameters in the url then you'll need to show that in the

map.connect 'projects/:your_parameter/draganddropsort, :controller =>

You can access that parameter in your controller with

It looks like you're right - thanks. Simply including fixtures.rb

I can't also use if sticking to those instructions. I suspect that I'll 
have to find another means to run the tests, avoiding fixtures.

[Rails] gem and rails3: LoadError

[Maurice Dubois]

Hi everybody,

I'm trying to use the prawn gem into a new rails3 application on debian.

What I did:

As root:
 - install rubygems, from
http://rubyforge.org/frs/download.php/73882/rubygems-1.4.2.tgz
 - gem install rails
 - gem install prawn
 - gem install pdf-reader
 - gem list | grep prawn =>
prawn (0.8.4)
prawn-core (0.8.4)
prawn-layout (0.8.4)
prawn-security (0.8.4)

As a user:
  - rails new myapp
  - cd myapp ; rails console =>
/usr/lib/ruby/gems/1.8/gems/activesupport-3.0.3/lib/active_support/dependencies.rb:239:in
`require': no such file to load -- prawn/core (LoadError)

Could somebody say what to do for prawn (or any other gem I suppose)
being
recognized in user's applications?

Thanks
Maurice

I think you did not define flash message in your controller action.
It should be like
 def create
  ...
   if @sector.save
flash[:notice] = t('flash.actions.created.notice')
   end
  ...
 end

I have not tested it but give it a Try.

Maybe just keep it very simple with:

map.connect 'projects/draganddropsort', :controller => 'projects', :action 
=> 'draganddropsort'

And just see if you can access the draganddropsort method by navigating to 
it in your browser. Also might be worth running rake routes to see what 
routes are getting set.

Even i think some mistake in routing ..i did some workaround on

I call draganddropsort method from roadmap view..and its route is been 
added like

map.with_options :controller => 'projects' do |projects| 
projects.with_options :conditions => {:method => :get} do 
|project_views|
.
 project_views.connect 'projects/:id/:action', :action => 'roadmap'

end
 Can anyone suggest possible routes that i can add.

[Rails] Re: ActionController::UnknownAction

[David White]

The only suggestion I can think of is to check there's no private or 
protected call on any of the lines above the method name or to check the 
routes file:

project_actions.connect 'projects/draganddropsort', :action 
=> 'draganddropsort'

Where is the project_actions coming from ? is it a block variable for 
map.resources :projects do |project_actions| ?

[Rails] Re: Running Spork with rspec in Rails 3 on Windows 7

[David White]

Rspec is compatible with Rails 3. https://github.com/rspec/rspec-rails

Have you looked at autotest (part of ZenTest) to save having to rake spec 
all the time. I'm sure I came across a windows Rspec, Autotest and Snarl 
notifications tutorial on the web once. A quick search will probably find 
it.

[Rails] Running Spork with rspec in Rails 3 on Windows 7

[veldtmana]

Hi,

As stated in the subject I require to set up the following:

Spork + Rspec on Windows using Rails3

It looks as if rspec is not Rails 3 ready yet and Spork does not play
nicely with Windows.

Is there a way to hack it all together or some viable alternative? the
time to run rake spec I killing me!

Any tips would be much appreciated

Regards,

Alex

[Rails] Re: Rails 3 + mongodb => test problems

[David White]

My only suggestion now would be that fixtures is part of ActiveRecord. If 
you're following that  tutorial then you removed the require 'rails/all' in 
favour of:

require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "rails/test_unit/railtie"

Which means you project doesn't include active record any more.

I did - sorry, should have mentioned it. That produces the same effect 
as putting it in test_helper.rb, ie.

undefined method `fixtures' for JobsControllerTest:Class (NoMethodError)

Checking back to my Rails 2 code I used to have fixtures :all in the 
test_helper, so perhaps something is missing as a result of using 
MongoDB.

yeah... wrong term... sorry for any confusion. Encapsulation and
separation of responsibility is more the gist of why I'd keep the User
and Profile stuff apart. All personal preference and project
requirements decisions though...
