Nevermind, I found the problem. I was supposed to remove the @ because 
it's iterating from a loop:

<% @users.each do |user| %>

<%

  user_link = link_to 'User Details', user, 
:class=>'first_and_last_name'
else
  user_link = link_to user.first_name + ' ' + user.last_name, user, 
:class=>'first_and_last_name'
end
%>

  <% user_name = user.first_name.to_s + ' ' + user.last_name.to_s %>

  
<%= link_to user_name, edit_user_path(user) 
%>
<%= user.title %>
<%= user.email %>

<% if user.role == 'admin' %>
  <%= user.role %>

<% if can? :update, user %>

  <%= link_to 'Edit', edit_user_path(user) %>
  <%= link_to 'Destroy', user, :confirm => 'Are you sure?', :method

[Rails] Having trouble with CanCan

So I got CanCan and Devise working well. I have two types of users:
Admins and Nonadmins. Admins can edit all of Nonadmins profiles.

The problem is, every user (either Admin or Nonadmin) belongs to an
Account or Organization. Admins should only be able to edit users from
their own Account or Organization. I was able to do that too.

The problem is, I can't display the links to the edit buttons.
Everything seems fine, I don't see any errors.

Here is what I have in ABILITY.RB
---
if user.role == "admin"

  # can :manage, :all

  can :manage, Account do |account|
account.try(:id) == user.account_id
  end

  can :manage, Appointment
  can :manage, Client
  can :manage, Service

  can :manage, User do |u|
u.try(:account_id) == user.account_id
  end

elsif user.role == "employee"

---
this is what I have on the file that lists the users:
---
<% if can? :update, @user %>

  <%= link_to 'Edit', edit_user_path(user) %>
  <%= link_to 'Destroy', user, :confirm => 'Are you sure?', :method
=> :delete %>

<% end %>

[Rails] Re: rvm and gem confusion

Besides rvm and the gem directory there I have a .gemrc in my home 
directory and a .gem directory. Not sure why I have it there. It stops 
my installation of Rails 3, complaining about permissions of the .gemrc. 
Is that something I've created or has it to do with Mac OS Snow Leopard? 
That is, can I delete them?

[Rails] How to Redirect from http://mysite.com to https://www.mysite.com on Herok

2010-12-01 Thread CuriousNewbie

Hello I'm looking to learn how to redirect all non-www (mysite.com) to
https://www.mysite.com

I tried the following:

class ApplicationController < ActionController::Base

  before_filter :check_uri


  def check_uri
redirect_to request.protocol + "www." + request.host_with_port +
request.request_uri if !/^www/.match(request.host) if Rails.env ==
'production'
  end


Problem with this is since the SSL cert on Heroku is for www.mysite.com,
and not mysite.com, the browser throws the nasty SSL HTTPS invalid
warning.

Any ideas on how to redirect in a way that avoids the nasty SSL HTTPs
invalid warning?

Thanks

Right, SQL databases cannot be assumed to guarantee this.  That's why I

Well, if you create the factories in order, then there's a significant 
probability of this happening...

Probably.  I may be wrong but I believe that postgreSQL does not even
guarantee that an unordered query will produce the same results if the
same query is run twice.  Conceivably therefore I could test without
the order clause and check it fails, then, thinking I had added the
order clause re-run the test and find it pass.  I think though as I
said in an earlier post that I can use common sense and assume the
probability of this is so small as to be insignificant.

I agree this seems like overkill and would likely be fragile.

Absolutely, I will check that the test fails before adding the order
clause, but see my reply to Marnen below.

I don't think that is a valid argument.  I think effectively what you
are saying is that it doesn't matter if it actually tests what it is
supposed to as long as it passes.  If you later discover that the app
is not doing what it is supposed to then add more tests.

I am not trying to test that ActiveRecord sorts correctly, I am trying
to test that I have correctly coded the scope.  I don't know how I
would assert that the named scope is passing the correct sorting
params.  Can you enlighten me?

I think what I will do is use some common sense rather than being too
pedantic about the testing.  By creating a number of records in a
random order and then checking that they are sorted correctly I think
the possibility of accidentally finding them come back in sorted order
is negligible.  In addition I will have checked that the test fails
before I add the sort clause.

[Rails] Re: Error installing rails 3, get error: mail requires i18n (~> 0.4.1, runtime)

2010-12-01 Thread Mike Moretti

The short answer:

My guess: I had installed ruby and rails about two weeks apart. I 
believe they were out of synch with each other, hence the problem. I 
uninstalled all my ruby gems including rails and reinstalled them one 
after the other and they all work now.

The long Answer:

I would like to thank all of you who responded and made sensible 
suggestions. I tried almost all of them. Indeed, somehow I ended up with 
two versions of i18n gem and by removing the more recent version and 
rerunning the command “gem install rails” it did seem to complete the 
installation without error. However, nothing would work properly. 
Something’s worked yet others things did not. For example when I 
generated a new rails project the directory contained only two files and 
not the whole subdirectory structure that was supposed to be created.

The solution:

I successfully uninstalled ruby by using control panel’s ADD/REMOVE 
option. Yet, my original ruby directory was still there which included 
some subdirectory and files. I removed that directory as well. I 
reinstalled Ruby and rails again. This time all went smoothly and 
nothing went wrong. It seems everything is working now. My guess is that 
since my installation of ruby and rails were two weeks apart, ruby gem 
and rails gem were out of synch. So by removing my entire ruby related 
gems/apps and reinstalling them one right after the other may have done 
the trick.

Again thank you all for your help.

Mike

Try creating the factories in a weird order.  If they still are returned 
in the correct order, then your sorting is correct.

...or...

Write the test so that it checks that the appropriate :order clause is 
set.  This is probably too invasive and implementation-dependent for my 
taste, though I might do it occasionally.

I think this is right... also I would recommend you trying to use gemsets --
I have found that making a gemset for each of my apps has been working
nicely, and makes them easy to find, i.e.

.rvm/gems/ruby-1.9.2...@wavelineup3/gems

Where wavelineup3 is the gemset I created under ruby-1.9.2-p0 installation
for one of my apps. See: http://rvm.beginrescueend.com/gemsets/creating/

These are my notes on getting pg to install on rvm -- I think the big deal
was to make sure you are pointing to the actual bin directory of postgres,
wherever it happens to be installed, so you might need to change the
directory:

  PATH=/library/postgresql/8.4/bin:$PATH gem install pg --no-rdoc --no-ri
  (note - the path is to the postgres server bin)

I believe you are a little lost about how the whole thing works. At
first you said you wanted to change the contents of 'datos' but now
you say you want to change the contents of the tag . I'll
assume from now on it is the later.

<%= title %>

I think there is a typo in your code. Shouldn't it be <%= @title %>?.
Besides that, I have never tried to replace the contents of an element
in the section so I'm not sure it will work. I'd appreciate
if you let me know when you get your code working.

For your code to work you would have to give an id to the element you
want to replace, as in:

<%= @title %>

The raw Prototype code to update the content of the title tag (without
ID) is as follows:

$$('title').first().update('Foo bar baz');

Perhaps you can modify your script to make that call.

Walter

Then it might be a good idea to create a partial and render it to
replace the contents of the tag , although returning just a
string might be OK. You would also need to tell your 'link_to' helper
which HTML element to replace ('title' in this case) and as I
explained before I couldn't see how to do that by looking at the API
with Rails 3. Somebody else already using Rails 3 might be able to
help better than me there.

The issue isn't really the filenames directly, but that URLs cannot

encoded either as %20 (in the path portion) or as + (in the query-

it might not be strictly correct per some RFC.

A URL must not contain spaces, which is why browsers will silently

You just found it -- or at least one -- apparently :-)

Spaces in file or directory names are brittle -- some programs will
handle them OK, some won't. You're far better off avoiding them.

Colin:

I would argue that it's unimportant -- even at the unit-level -- *how*
the test is passing. If every time you run the test it passes, then
the code does what you specify it does. When there's a problem,
identify the bug and write a new unit, integration, or functional test
that eliminates the unexpected behavior, then make that test pass.

I might also argue that it's not up to you to test ActiveRecord. You
might assert that your named scope is passing the correct sorting
parameters to ActiveRecord; at that point, it's up to ActiveRecord to
hold up its end of the bargain.

What do you think of that?

[Rails] Re: Update div with Prototype

2010-12-01 Thread Alberto B.

The title variable is to change the title when the page is refreshed.

What you're doing with link_to_remote is what I want it.
The problem is that Rails 3 does not work the "remote => true" in the 
"link_.to" and is supposed to be the equivalent of link_to_remote in 
Rails 2.
And if I remove the option of remote: true, refreshes the entire page 
and not the HTML element that I want, in this case datos div.


Thank you.

AFAIK everything related to RVM is stored inside ~/.rvm. I've 
reinstalled before by simply deleting the directory and reinstalling.

If you want to know details about your RVM environment use...

rvm info

It will tell you where to find the gem folder and exactly what gemset 
you're using. All of this information can be found in the RVM docs on

[Rails] Mongrel, .htaccess, cpanel, rewrite, Mongrel::HttpParserError

2010-12-01 Thread Ralph Shnelvar

I just installed my RoR application on my ISP's server.

This is a Cpanel environment and it creates a .htaccess file:

  RewriteEngine on

  RewriteCond %{HTTP_HOST} ^xyz.com$ [OR]
  RewriteCond %{HTTP_HOST} ^www.xyz.com$
  RewriteRule ^(.*)$ "http\:\/\/127\.0\.0\.1\:12001\/$1" [P,L]

in a public_html directory.  (I changed my domain name in the text above
to xyz because we are not ready to do a product launch.)

The objective, I guess, of the .htaccess file in public_html is to
rewrite (i.e. redirect) www.xyz.com to 127.0.0.1:12001


When I access my website using
  www.xyz.com:12001
everything works fine.   All my pictures show up, all links work, there
are no errors in production.log and the only error I see in mongrel.log
is

  Rails signals registered.  HUP => reload (without restart).  It might
not
  work well.

But that message only occurs during mongrel startup.


When I attempt to access my website via
  www.xyz.com
or
  xyz.com
I get a ton of mongrel errors complaining that

  HTTP parse error, malformed request (127.0.0.1):

There is a shorthand for specifying the "notice" flash in the
redirect_to call. You were very close to having it correct.

The format is this: redirect_to(options = {}, response_status = {})

The :notice needs to be in the response_status hash.

The problem you had is that that :action and :notice were both passed
in the options hash. You can use the shorthand by explicitly
separating the hashes:

redirect_to( { :action => 'edit' }, :notice => 'User was successfully
updated.' )

[Rails] How to test sort order in named (or default) scope

Hi
I have a named scope that sets a sort order.  In my unit test I can
run the query on a set of records (using Factory or fixtures) and

I be sure that it is not just accidental that they are in the correct
order?

[Rails] Re: Redirect to edit form after update

ALRIGHT!! AWESOME!!!

Simple and it works!

I did this...

flash[:notice] = 'User was successfully updated.'
respond_to do |format|
  if @user.update_attributes(params[:user])
format.html { redirect_to(:action => 'edit') }
format.xml  { head :ok }
  else
...

Thanks Colin!

You don't want the :notice bit, just make sure that the flash is shown
on the edit page as it is on the show page. Probably something like
<%= flash[:notice] %>
in the layout. and set flash[:notice] in the update action (which it
probably is already).

[Rails] Redirect to edit form after update

By default, the controllers are coded in a way that you will be
redirected to the SHOW page of the item you are updating.

For example, if I edit a user, after I click the submit button, I will
be redirected to the SHOW page of that users.

Instead of being redirected to the SHOW page, I want to stay in the same
EDIT page with a notice that the user has been updated. How can I
accomplish that?

I tried this...
format.html { redirect_to(:action => 'edit' , :notice => 'User was
successfully updated.') }

And it did get me redirected to the EDIT form. But I don't see the
notice message and the resulting URL is this:
http://localhost:3000/users/4/edit?notice=User+was+successfully+updated.

So I must be doing something wrong.

[Rails] Re: Update div with Prototype

2010-12-01 Thread pepe

Hi,

I have not used Rails 3 yet and I see by your link_to helper that's
what you are using. Sorry if I can't be of much help, but I'll try to
point out what I see here that _could_ be wrong.

div class="menu_activado">
<% = link_to "Link", about_path,: remote => true%>


I am assuming the first div is missing the opening '<' because of a
mistake while copying the code?

A quick look at the Rails 3 API does not show how to indicate that you
want to update an HTML element's contents. Compare the link above with
the following, based on Rails 2.3.5:

<%= link_to_remote 'Get Time',
  :update   => 'current_time',
  :url  => {:action => 'get_time' },
  :complete => visual_effect(:hightlight_shake, :current_time) %>


Notice the :update line? It indicates what HTML element to update with
the contents returned by the server. I can't see in the Rails 3 API
how to do that. Maybe it's explained somewhere else but not in the
link_to helper docs, as far as I could see.

>     
>         <%= render 'layouts/header' %>
>         
>             <%= yield %>
>         
>         <%= render 'layouts/footer' %>
>     
>

I am not sure you really want to replace the contents of 'datos'. That
would replace the contents of the whole page except for the header and
the footer.

> class PagesController < ApplicationController
>   def about
>     @title = "About"
>   end
> end

>From the link_to_remote Rails 2.3.8 API:
"Returns a link to a remote action defined by options[:url] (using the
url_for format) that’s called in the background using XMLHttpRequest.
The result of that request can then be inserted into a DOM object
whose id can be specified with options[:update]. Usually, the result
would be a partial prepared by the controller with render :partial."

The last sentence is the important one. Your 'about' action does not
render anything, it only assigns a value to a variable. The returned
value of your action will be the string 'About' and that should be
what you get in 'datos' after the code executes, supposing that the
div gets updated.

[Rails] What is "Ruby on Rails" in your Language?

2010-12-01 Thread Edmond Kachale

RoRers,

I am often interested with technologies that interface with natural
languages. These include machine translation systems, automatic (POS)
taggers and speech recognition systems, to mention a few. Above all, I am a
hardcore preacher of localization of software.

I am curious about the *literal translation* of the phrase "Ruby on Rails".

Q: What is "*Ruby on Rails*" in your Language?
A: In my language, *Chichewa*, (a language in Malawi. ISO codes ny, nya.), "
*Ruby on Rails*" is *"Njero pa Njanje"* (read as *Njéro pâ Njânjé*).

This question has been influenced by some the code snippets I have been
seeing on this forum. They contain non-English words. They excite and
energize me very much.

Of course, "Ruby on Rails" is a proper noun which is often not literally
translated in localizations, but I am just curious about it.

More blessing,

I guess that it took the whole of the rest as the title, since the
title had not been closed.  You would have seen the problem if you had
copied the complete html of the page (View, Page Source or similar in
the browser) and pasted it into the w3c htlm validator website.  It
would have told you about the error.

A good tip when something apparently very strange like this is
happening is to look at the html source, you would then have seen that
there was something there that should have been displayed but was not,
this would have told you that it must be an error in the html rather
than any subtle rails issue.

[Rails] Re: rvm and gem confusion

2010-12-01 Thread Gogov

I recently had to reinstall rvm when I was upgrading from rails 3.0.0
to rails 3.0.3 (maybe too harsh but it worked), so in order to remove
the cached gems (on a single user install), I removed all the stuff in
$HOME/.rvm/gems

Btw, I don't think you should've used sudo in the first place so maybe
just doing a fresh single user install without sudo will help you.

AFAIK, deleting .rvm is the recommended way on rvm's site to delete a
single user install.

Thanks! Perfect.

I'm also waiting for a fix in 3.0.4. As you asked: Does anyone know if 
patch and Git exists in windows? If no; how to apply std nix patch 
files?

About mysql og not. It's religion, you know :-) I've used Oracle on 
Unix/Linux through many years. I like mysql, though.

Now I have a another problem. It works in my development environment but
no in production.

*** Exception ArgumentError in
PhusionPassenger::Railz::ApplicationSpawner (No association found for
name `machines'. Has it been defined yet?) (process 16052):
 from
/usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/nested_attributes.rb:245:in

But I don't understand why.
