Irrelevant to the question and bad advice anyway.  Rubystack doesn't 
seem particularly well suited to Mac OS.

> And the problems were...?

I'll take another run at ActiveScaffold in a week or two.  Right now,
I'm applying ruiby-debug and logging in place of my long-years of
inserting ad hoc debugging, e.g puts in Ruby or printf in C++.  But
I'm letting A.S. distract me from my current path.

Nevertheless, thanks for asking.  I WILL get back to A.S. soon.

Best wishes,
Richard

[Rails] Re: Ajax fails in IE8

2010-06-04 Thread ct9a

Hi, Colin,

  Every page I make has to pass by W3C's validation.

It's a pity why IE8 doesn't really support prototype and rails' JS
helpers are made out of prototype...

Any more ideas guys?

[Rails] Visual Effect: insert new stuff, then slide open

2010-06-04 Thread Chris Kalaboukis

Hi guys: Thanks for your help so far - think I've progressed pretty far
down the Rails front but I think I'm getting stuck, maybe you can help
me out:

I've got a twitter like app where I'm trying to display new tweets as
they come in. This is what I'm doing right now:

render :update do |page|
page.insert_html :top, 'tweebs-box', :partial => 'livetweebs'
end

...which, of course, takes the new content and inserts it before the
current set on the screen. What i'd like to do is to have it slide down
elegantly upon the insert, instead of just snap down. I've been thinking
of an easy way to do this but this is the only way I can think of: maybe
there is an easier way?

1. display the page the first time with a div for the current stuff and
a hidden div above it for the new stuff to come
2. load the content into the hidden div
3. slide down the new div, thus pushing the current div down
4. insert a new div above this div for the next set to be inserted into

Is there an easier way?

Thanks...Chris

It probably is, but I've run into problems a couple of times,  so I
shelved the idea for the time being.  Anyway, writing some Ruby to
manipulate a Rails app is fun.  And I did post my question on the Ruby

You've got it backwards.  foreign_key gives the name of the key on the 
other table, so in this case, it would be 'rating', not 'id'.  But why 
not follow the Rails conventions, call the column Player.rating_id , and 
drop the foreign key clause?

[Rails] New to rails, a little model help please

2010-06-04 Thread Alex Smith

Hey guys I'm having a little trouble what I think should be a pretty
simple relationship between tables.

Player.rating is a f-key to Rating.id, both fields are integers

When I try to add a new player I get this error message

ActiveRecord::AssociationTypeMismatch in PlayersController#create
Rating(#38968656) expected, got String(#19165136)

In my form I have this for the rating dropdown
f.select :rating, options_for_select(Rating.all.map { |r| [r.level,
r.id] })

In my models I have

#player
has_one :rating

#rating
belongs_to :player, :foreign_key => "id"

The controller is pretty straight forward
  def create
@player = Player.new(params[:player])
respond_to do |format|
  if @player.save
flash[:notice] = "Registration Successful"
format.html { redirect_to root_url }
  else
flash[:notice] = "Error in registration"
format.html { render :action => "new" }
  end
end
  end

Any guidance?

[Rails] Mac OS/X and Rails 3 ?

2010-06-04 Thread Audrey Lee

Hello List,

Label me a newb, but how do you install Rails 3 on your Mac?

Google sent me to these URLs:

http://weblog.rubyonrails.org/2010/2/5/rails-3-0-beta-release/
http://guides.rails.info/3_0_release_notes.html
http://asciicasts.com/episodes/200-rails-3-beta-and-rvm

>From early Feb 2010 I see this short recipe:

gem install tzinfo builder memcache-client rack rack-test rack-mount
erubis mail text-format thor bundler i18n

gem install rails --pre

On April 1 2010 we have this from DHH:

gem install rails --prerelease after you make sure you’re on Ruby Gems
1.3.6 with gem update --system


But today is June 4 2010 and I'm curious if there is a more current
way to install Rails 3 on a Mac?

Also I noticed this on github.com:

http://github.com/rails/rails/tree/v3.0.0.beta.3

How do I install that?

If it were rails 2.x I would just git-clone it into /vendor/ and call it /rails/

Side note, my Ruby comes from rvm and it currently looks like this:

$
$ ruby -v
ruby 1.9.3dev (2010-06-04 trunk 28157) [i386-darwin9.8.0]
$
$

$
$ gem list

*** LOCAL GEMS ***

rake (0.8.7)
$
$


$
$ which gem
/Users/maco/.rvm/rubies/ruby-1.9.2-head/bin/gem
$
$

$
$ gem -v
1.3.7
$
$

Help !?!?

[Rails] [Rails 3] How to refer to birthday(1i) in a AR

2010-06-04 Thread ShellScripter

Hi , there , first of all i wanna to express my regard to the Rails 3
dev. team's effort ,
the work is really amazing ! Really speed up a lot the performance !!

Well , i still a rookie guy and have a question for ask T_T :

i have two association ARs : User has_one Account , and i have used
the
accepts_nested_forms for get all create up for only one line of code
in view
: @user = User.new(params[:user]

until this part i have done with the tutorial of RailsCast
http://railscasts.com/episodes/196-nested-model-form-part-1

However , in my Account AR , there is a birthdate colum ,
( t.date :birthdate in the migration)
, i have used the date_select helper to generate the corresponding
html code , and
get the return values : year , month , day with  birthday(1i) ,
birthday(2i) , birthday(3i)
, i have tried to use the virtual attribute in the Account AR for
combine all these values ,
but i can't refer them with
attr_accessor :"birthday(1i)", :"birthday(2i)" , :"birthday(3i)".

I don't know if there is another solution for kind of this , or
another way to get my objective:
get date(year, month, day) from html and combine name all in a
birthday value for save @_...@??

Thx in advance !

[Rails] Free Webinar! Using Cucumber + Webrat to Test Ruby Apps in the Cloud

2010-06-04 Thread Ashley

Thursday, June 15, 2010 at 11 am PDT
Register here: http://bit.ly/abJDuC

Cucumber, a Ruby on Rails tool, is incredibly useful for the full-
stack testing of web applications. Using domain-specific language that
reads similarly to plain English, it allows non-technical domain
experts to write executable requirement specs. By default, Cucumber
comes packaged with Webrat, a powerful testing tool that emulates a
browser that is many times faster than a normal one. Though Webrat
lacks support for JavaScript, it can be configured to use Selenium to
test for any cross-browser quirks in the JavaScript code using live
browsers.

In this webinar, Sauce Labs Developer Sean Grove will demonstrate how
to quickly set up a Cucumber application from scratch, and then
configure it to effortlessly switch between Webrat and Selenium. We'll
discuss the advantages of each tool and how to know which tool best
fits the situation. Finally, we'll go over how to overcome some of the
biggest problems of Cucumber and Selenium by using the Sauce OnDemand
platform.

Who should attend: Web developers and QAs with any level of Selenium
skills

Current testing environment: Preferably Ruby + Cucumber

Hosted by: http://saucelabs.com

And what would a native interface be in this case? "Mainframes" can run 
lots of different DB servers.

Of course there are such things as right and wrong.  And that's even 
more true where it concerns proper development practice than abstract 
philosophy.

If you disagree with the advice you're getting, that's fine.  If you're 
claiming that there is no right or wrong...well...then I don't want to 
be the one maintaining your codebase. :)

Development and architecture are all about value judgements -- deciding 
what the right way to do things is for a particular set of conditions.

And with that, let's leave philosophy and return to software 
development.

I am interested in native support. Of course it's possible to integrate 
Ruby with a mainframe if the mainframe exposed a http endpoint; this is 
beyond obvious.

[Rails] Ajax, jQuery

2010-06-04 Thread Ralph Shnelvar

I am not sure where I should post this since this seems to be an
"interdisciplinary" problem

I am having trouble communicating between my javascript and my Rails
app.

Here's the snipped of code from my controller
- - -
  def poll
p params
puts "Got here:"
# debugger
@some_object = 12345
respond_to do |format|
  format.json { render :layout => false,  :json => @some_object }
end
  end
- - -


I see
- - -
{"comment"=>"ch", "_method"=>"PUT", "action"=>"poll",
"controller"=>"reviews", "_"=>"1275680223825"}
Got here:
- - -
in the Webrick console log


Here's the relevant javascript:
- - - -
pollWithAjax = function() {
  $.ajax(
{
  // Define AJAX properties.
  type: "GET",
  url: "/poll",
  dataType: "script",
  data: { _method: 'PUT', "comment": 'ch' },
  timeout: (10 * 1000),
  beforeSend: function(xhr) {xhr.setRequestHeader("Accept",
"application/json")},

  // Define the succss method.
  success: function(){
alert('pollWithAjax Success')
  },

  // Define the error method.
  error: function( objAJAXRequest, strError, errorThrown ){
alert("pollWithAjax Error! Type: " + strError);
  }
}
  );
};
- - - -

The "error:" function returns with the value of strError being "error".


This is what FireBug says my headers look like
- - -

When I click on the response tab in Firebug, I see nothing.

Am I setting up the headers incorrectly?

Solved.

I double checked both of these items, but both were in order.  I solved 
the problem by grabbing hold of a libmysql.dll file and dumping it in 
C:\Ruby\bin, and all was well.  Windows is so touchy...

If you look at JRuby rather than 3 year old articles about AR in Java,  
you might be in a very happy place. JRuby lets you call Java from Ruby  
and there would be essentially zero cost to it.  You can run Rails  
under JRuby, too.

[Rails] Embedding a form is lots of various place

2010-06-04 Thread theduz

Hi,

I've been asked to put a 'contact us' form in many and various places
on our site.  Initially, I proposed we simply link to the contact us
form, which is already handled by a model, view and controller, but
the users would like the form itself to appear.  I can certainly
enclose the form in a partial, and include the partial, but then it
seems I have to update many and various controllers with code to
support the form loading, submission, and saving.  It doesn't seem
very dry.

Another thought - I could build the contact form controller and
view(s) with no layout, and then include the URL to the contact form
wherever necessary via iframe.  I think that would be workable, but
doesn't seem very rails-like.

Is there a rails idiom for including what I would term 'an unrelated
and self contained form' within some other model/view/controller ?


Thank you.


Regards,
Rich

Rails is not the only RESTful game in town.

Not lightweight so much as modular.  Rails generally wants to use AR or 
something similar (though this is less true of Rails 3 than Rails 2).

Easy.  JRuby or RJB.

You shouldn't need to do it that way, if I understand correctly.

In this case, you are wrong.  Rails is a full-stack framework.  If 
you're not going to use most of the stack, there is no point in 
incurring the extra overhead of using it in your project.

[Rails] Ajax post from a mobile app

Hi,
I'm a trying to create a user using Ajax from a mobile app with
javascript and I'm struggling!!!

Here is what I'm trying:
user = {username:'plop', password:'plip', password_confirmation:'plip'};
new Ajax.Updater('all', HOST + 'users/create',{
  method: 'POST',
  parameters:{'user': user}
});

When I look at the log It seems that is doesn't recognize first that is
a POST method and it doesn't recognize my user parameter.

Here is the log:
Processing UsersController#create (for 127.0.0.1 at 2010-06-04 20:40:07)
[OPTIONS]
  Parameters: {"action"=>"create", "controller"=>"users"}

Here is how it should be:
Processing UsersController#create (for 127.0.0.1 at 2010-06-04 20:35:46)
[POST]
  Parameters: {"commit"=>"Submit", "action"=>"create",
"authenticity_token"=>"/fkA8CQVp88xDB1Tbf/T2OHldbpc0QQlsBk7yk/7mxA=",
"controller"=>"users", "user"=>{"password_confirmation"=>"[FILTERED]",

[Rails] sqlite specified in database.yml, rails tries to use mysql

2010-06-04 Thread Les Peabody

Hi All,

I've run into an interesting (and annoying) problem.  I have a
development environment on a Windows machine and on a remote Linux
machine.  I cloned my environment on the Linux machine over to my
Windows box.  I have installed all the required gems for the project.
When I try to reconfigure database.yml to use sqlite3 instead of mysql,
and when I try to do a 'rake db:schema:load' I get prompted with an
error box saying:

"The program can't start because LIBMYSQL.dll is missing from your
computer.  Try reinstalling the program to fix this problem."

I have no idea why it would even be trying to access a mysql dll if I
specified that it should be using sqlite3.  Any thoughts?

Thanks,
Les

Quite so.  The bad idea here is using Rails only for the presentation 
tier.  If the OP is really dead-set on using Rails and on reusing the 
Java data access framework, then the right thing to do is to write an AR 
interface to the data access framework.

Right.  That's the *only* way in which I'd even consider using Rails in 
the OP's situation: writing an AR interface to the existing data access 
framework, if AR cannot replace it altogether.   But it really sounds to 
me like the OP is making his own life difficult by trying to shove Rails 
in somewhere that it doesn't really fit.

Then you are making a very poor decision.  Stop now.  Rails is an 
end-to-end solution.  Either use it as one or go with something like 
Sinatra or Ramaze that is better suited to your use case.

I thought for a second about attempting to answer this, but quickly 
realized. DO NOT DO THIS!

Pessimistic locking on databases is very, very bad form. Do not attempt 
to prevent concurrent editing. You're just asking for trouble. Users of 
modern applications will not accept pessimistic style record locking.

Instead, develop a recovery solution based on an optimistic locking 
scheme. ActiveRecord has some built-in support for optimistic locking, 
which will get you started. If the optimistic locking mechanism detects 
concurrent edits then present that to the user with enough information 
to recover.

P.S. Using *.rhtml extensions is so one-dot-ex.  If you're using a 
version of Rails 2.0 or higher, switch your views to use *.html.erb.

The point of avoiding ActiveRecord is because our data sources are 
disparate, meaning that they include databases, mainframes, and, in some 
cases, sources that expose only a message-based interfaces (JMS, etc). 
Furthermore, data from these sources needs to be mapped and processed 
through rules before being populated in model objects and presented to 
the client. Our Java data services layer handles all of this, so it's 
just a matter of integration Rails/Ruby with that interface. We intend 
to use Rails for our presentation tier only, not as a end-to-end 
solution.

The Java framework already exists, and we want to reuse what we have 
available.

Does that make sense now?

That doesn't follow.  ActiveRecord is capable of dealing with multiple

Can't you just use ActiveRecord and ActiveResource?  You probably don't 
need the Java framework, unless there's something I don't understand

So when using ActiveResource as the base for a model class, it basically 
populates the model using an external http resource? Like this...

 class Person < ActiveResource::Base
self.site = "http://api.people.com:3000/";

[Rails] Alternative to ActiveRecord for populating model objects??

Hi,

We are using Ruby on Rails for an internal project. The data for our
model objects exists in many different data sources (database,
mainframe, etc), so we we need to avoid using ActiveRecord. Our
development teams built a data service layer in Java that provides
access to our company's information. We want to place Ruby/Rails in
front of this data service layer and integrate our model components to
get populated from that same Java layer.

So, we want to replace ActiveRecord in our model classes and replace it
with code integrated with our Java data services framework. Is there an
example that demonstrates how to replace ActiveRecord with Java code?

Thank you

Just a thought, have you checked that your html is valid by pasting

Have you looked for it on your hard disk? It may be already installed but

When you find it you could copy it into c:\windows\system (or somewhere

I'm not intending to insult, I just don't like it when people point
out the most obvious thing to solve the situation especially when it's
in an error message.

At any rate, I'll have to go down to Ruby 1.8.6 and see if this works.

Yes, that's normal behavior in development mode.

Because it's a different kind of caching.  JavaScript caching simply 
involves using the browser cache for included files, whereas controller 
caching involves Ruby objects in memory on the server.

Haml and Sass shouldn't be having that effect.  Look elsewhere for your 
problems.

The fact that you're asking this makes me think that you want *page* 
caching, not controller caching.

[Rails] How to show a Timer for lock expiry when editing a record

2010-06-04 Thread Vijay

I'm newbie to ruby on rails.
In my application, i was trying to show the remaining time the user is
allowed to edit an instance record( like milestones, cheklists etc.).
I was locking it from multiple users to edit it at the sametime.
When the user clicks the edit link_to i need to display the timer in
the edit.rhtml


I have the javascript function for timer updation. when called it
updates the text_field with the time.

function update_timer() {
var page_loaded_ms = new Date().getTime();
var timeout_ms = 100*1000;
var time_left = Math.round((timeout_ms - new Date().getTime()
+ page_loaded_ms) / 1000);
var minutes = Math.floor(time_left/60);
var seconds = time_left - (minutes*60);
$('time_left_value').value = 'Time left: '+ minutes + ' min' +
zeroPad(seconds, 2)+ ' sec';
setTimeout("update_timer()", 1000);
}

function zeroPad(number, width) {
var s = number.toString();
while (s.length < width)
s = "0" + s;
return s;
}

could anyone suggest me a solution for this.

You're going to have to be a little more specific - the regular
expression /0/ matches the first string and not the second but that's
probably not what you wanted.

[Rails] Ajax fails in IE8

2010-06-04 Thread ct9a

hi guys,

  I am testing a new optional funtionality in my site with IE 8 after
success with Firefox 3.6.3, chrome and safari.

 The new functionality basically sees a "sub category" drop down list
get generated in my form as soon as a "Category" value is selected
from the "Category" drop down list.

 I have been using the standard rails api such as observe_field, and
collective_select.

Anyway, when I loaded up the webpage on IE8 and selected a value from
the "Category" drop down list, the form fails to show the subcategory
drop down list.

Ajax doesn't seem to be working here in IE8.
 I know that rails uses prototype.
 I have read that prototype 1.6RC2 is fully compatible with IE 8
(http://www.prototypejs.org/2009/3/27/prototype-1-6-1-rc2-ie8-
compatibility-element-storage-and-bug-fixes) .
I downloaded it and reloaded the webpage . No difference.

1) has anyone managed to get around the problem whereby ajax use in
IE8 fails?
2) has anyone got an alternative such as using observe_field/
observe_form and calling the whole url (appended with the selected
values at the time to load the other dynamic values (in this case,
category id which is appended to the url which would then load the
whole page with a bunch of sub category values ) )?

thanks

I believe that's correct.  But you should never need Ruby within 
JavaScript, nor should you ever need JavaScript within HTML (it's best 
to put it in a separate file).

Probably.

I'm surprised that #{} works here.

If you think you need Ruby in your JS, you've got a design problem.  Fix 
it.

If you use Sass (which I highly, highly recommend) then this is done for 
you.  You get lots of other advantages too.

[Rails] Re: difference between belongs_to and references keyword?

Correction to my previuos message: you can use "belongs_to" and
"references" as column types in scaffold (and migrations). They do
same thing: add belongs_to association to model.

Hey Smit,

Seem to be having the same issue myself whilst trying to install the

If anyone else could help shed some light on the situation it would be
greatly appreciated.

Thanks

[Rails] Password re-check with authlogic

2010-06-04 Thread Albus Dumbledore

Hi there!

I know what I am trying to do would seem laughably easy to some, but
pray accept my excuses for still being nothing more than a newbie where
rails is concerned. It seems there is so much to learn. And with rails
it's always not about doing it, but doing it easily and meaningfully,
i.e. I'm asking how to do it the RIGHT way.

Now, I am having a very simple User/Session model (implemented using
Authlogic). In fact it is so simple, that all the functionality
regarding profile editing is put on ONE page. I'd like the user to be
able to set some details AND to be able to change their password. In
case the user desires to change their password, i.e. does NOT leave the
password field blank, they must be required to enter their current
password (sounds logical enough to me) in another field.

However, there are a couple of problems I am experiencing with this
simple scenario.

Firstly, how could I tell the User model to forget about the password
fields and NOT save them if they are empty (I know how to validate them
but that alone doesn't seem to do it) and so Authologic wouldn't
complain either?

Secondly, is there any way to validate that the entered password in the
`password_check` field matches the current one, but do it using custom
validation callbacks (i.e. in the model, not in the controller)? I don't
see how one could have access to the params hash from within the model
validation methods (and it doesn't seems right to me to do so) so should
one use virtual attributes to do the check?!

Thirdly, even if all that validation was done in the controller (i.e. if
it is not possible to be done in the model), does anyone know how I am
to compare the entered password and the current one for it is stored in
encrypted form. There must be some method in Authologic that should be
able to do just that (i.e. not reviling the password, but comparing an
entered password against the current one).

And finally, is there any way to add errors to an ActiveRecord object
from within the controller (not the model) so as to be able to show them
along with the other validation errors if I can't make that validation
in the model?

Thank you awfully much!

...and sorry for the bunch of words but it's incredibly hard to express
extremely simple things simply.

[Rails] Can Rails cache a Controller "as long as code not changed"?

2010-06-04 Thread Jian Lin

At work, we have a situation where when

  script/server

is run, then all the controller code is cached.  This is to speed up the
development server.  But that will mean that whenever we change the
controller code, we need to restart the server.

So we can turn off the caching of controller code all together.  But
can't there be mechanism that is similar to the inclusion of javascript

  foo.js?1273424325

which is to use the cached version as long as there is no code change,
but recompile it when there is code change?

Maybe because we use HAML and SASS a lot, loading some page (such as the
homepage of the site) can take 40 seconds on the dev environment and it
is quite long.
