Look carefully and you will see that t is an array, containing all
rows that match, though only one in this case.  so you must do
t[0].name or t.first.name or similar.  I am not sure why t.name
evaluates to Ticket though.


 irb(main):004:0 t = Ticket.find 2

As you have asked for a single row this time it is not an array.

So your test is failing.  Either you have written the test incorrectly
or your application is not right.  If you do not understand why the
test is failing show us the code of the test and we may be able to
help.

Because it's not actually an array, it's a Arel scope and you can call
class methods on such scopes (the method is called with conditions
etc. set by the scope). In this case it's not very useful because the
class method name just returns the name of the class but it still
works.

If you cannot see what is wrong with that code (the code that prevents

You should possibly not be using .create as that does a save at that
point. The save will fail (because there's no story) and a won't be
assigned anything.

instead, try:
a = Annnette.new(:story = nil)

Or load a valid Annnette from your fixtures (or factories), set the
story to nil, and check the errors.

It is a very simple app made with scaffold to try and understand the 
problems with my main app which started this thread.

 I am losing track of this conversation.  I think we had better start
 again.  Can you explain:
 1. What the test you wrote is attempting to check.
 2. What code you have written in the application to perform the
 operation that the test is checking.

 Colin

 1.It should show an error if an attempt is made to create a story
 without a story entry.
 2.This is from annnettes_controller.rb

 def create
   �...@annnette = Annnette.new(params[:annnette])

    respond_to do |format|
      if @annnette.save
        flash[:notice] = 'Annnette was successfully created.'
        format.html { redirect_to(@annnette) }
        format.xml  { render :xml = @annnette, :status = :created,
 :location = @annnette }
      else
        format.html { render :action = new }
        format.xml  { render :xml = @annnette.errors, :status =
 :unprocessable_entity }
      end
    end
  end

I don't see anything there stopping a save if there is no story.
Anyway this code is not called when you call Annnette.create, the
create method of the model is called.  As Michael has pointed out you
probably want to use new rather than create in the test, but you still
need code to stop the save if there is no story.  Usually this would
be done by a validation in the controller.

If you're writing code to validate db updates in your controller, and
trying to test them with unit tests, I suggest you take a couple of
steps back, buy and read the Agile Web Development With Rails book,
and move forward from there.

Re: [Rails] Re: How do I create a function

I have a rails app.  I understand how to create a function in Rails.

I have a contact that is viewable by multiple users.  I want to create a

I assume I create a new function in the action controller or contact 
controller like:


def lock(contact_id)
  c=Contact.find(contact_id)
  c.locked = 1
  c.save
end

def unlock(contact_id)
  c=Contact.find(contact_id)
  c.locked = 0
  c.save
end


Is this the proper way to do this?  How do I make sure it's not 
accessible through the through the URL: /Contacts/lock?
  
You can create a 'private' section in your controller if you have 
something which belongs in the controller.  The stuff in private is 
accessable from methods in the controller but not through the url.

If you just want a test that works then change your existing test to
one that checks that you _can_ create an object if you _do_ provide a
story, use new instead of create and change the assert to assert_nil,
something like

class AnnnetteTest  ActiveSupport::TestCase
 def test_should_be_valid_with_story
a = Annnette.new(:story = 'Neil')
assert_nil a.errors.on(:story)
end

[Rails] Re: select helper with boolean and null/nil values

2010-11-20 Thread pepe

 At that point, you *did* need it.  Ugly or repetitive code is an example
 of a need -- in this case, for refactoring or generalization.

There might have been a 'personal' need but I don't think that makes
it a *real* need. The ugly code was just the way it is done. Changing
it was like saying I don't like the way Ruby lets me assign strings
to a variable so I am going to change it. and then you come up with
something that replaces my_var = 'my string'.

[Rails] Equivalent to View Page Source; No AJAX

2010-11-20 Thread Ralph Shnelvar

I am developing a website that does not use AJAX.

What I would like to be able to do on the server side is find the point
in RoR (assuming it exists) where the HTML is rendered and capture
that string so that I can manipulate it for my purposes.

To be a little clearer, the user at their browser can do a View Page
Source and then save that HTML to a file.  I would like to generate
(i.e. capture) exactly the contents of that string/file on the server
side so that I can save it on the SERVER.

I am not asking for the client to send back the contents of the View
Page Source back to the server.  I do not wish to interfere with the
sending of the HTML to the client.   I just want to get a copy of that
HTML so that I can save it to a file on the server and have that file
have exactly the same contents as a View Page Source and then Save File
as that file would be on the client.

Is this possible and/or easy to do?

You could probably do that from an after_filter - you should be able
to play around with response.body.

[Rails] Re: no route found to match - Routing Error on Dreamhost

2010-11-20 Thread Gonzalo Serrano

I'm a newbie to Ruby/Rails as well. When I tried 'my_test' in the URL 
(i.e. http://localhost:3000/my_test/index), and all permutations of it 
thereafter, I still kept getting the 'no route to found to match...' 
error. However, there is a configuration in the routes.rb file that will 
make these URLs work (apparently, since Rails 3, this is the 
configuration to put in). Just insert the below configuration anywhere 
in the routes.rb file

  match 'my_test/index' = 'my_test#index'

Restart Rails after this, and try the 
http://localhost:3000/my_test/index URL again. Hopefully, that should do 
it.

Good luck,
G.

What happens if you run one of the tests explicitly, for example
ruby -I test test/unit/comment_test.rb

That is a capital i in -I test, telling ruby to include the test folder.


Otherwise I am getting out of my depth I think.  Can anyone else
suggest what the problem may be?

From the stack trace, it does look like it's failing at story_test
(unless that list of test files includes every single test in the
directory...).
As an extension of Colin's suggestion to run one test; what if you
remove the story_test.rb file from the directory to test running
everything *apart* from that.

If it works without the story_test, I'd guess there's something in
there that's making it not parse...

[Rails] Global text search (and replace) on MacVim?

Been trying out Macvim and I think I have covered most of what I used in
other editors except for how to handle global searches and replaces for text
in files (i.e. not looking for file names, but search and replace text
within all files below a specific directory). Can anyone who uses MacVim
tell me what they use for such tasks? I have been poking around and see
:grep as the main method, although not sure if I can use it to do a replace?
If you can give me a few examples specific to MacVim that would be great.

Thanks,

David

[Rails] Gem environment has wrong ruby version

2010-11-20 Thread Eddie Du

Hi all,

This appears to be wrong, I'm not sure how to fix it.
Here's my output from gem environment


RubyGems Environment:
  - RUBYGEMS VERSION: 1.3.7
  - RUBY VERSION: 1.8.7 (2010-01-10 patchlevel 249) [x86_64-linux]
  - INSTALLATION DIRECTORY: /usr/lib/ruby/gems/1.8
  - RUBY EXECUTABLE: /usr/bin/ruby1.8
  - EXECUTABLE DIRECTORY: /usr/bin
  - RUBYGEMS PLATFORMS:
- ruby
- x86_64-linux
  - GEM PATHS:
 - /usr/lib/ruby/gems/1.8
 - /home/ed/.gem/ruby/1.8
  - GEM CONFIGURATION:
 - :update_sources = true
 - :verbose = true
 - :benchmark = false
 - :backtrace = false
 - :bulk_threshold = 1000
  - REMOTE SOURCES:
 - http://rubygems.org/


And here's ruby -v


ruby 1.9.1p0 (2009-01-30 revision 21907) [x86_64-linux]


So gem has the wrong version of ruby in the environment. I suspect this
may  be the reason of some weird errors I've been seeing. So how do I
change the gem environment?

Thanks,
Eddie

[Rails] How to get the :remote = true working to update a part of the page?

2010-11-20 Thread daze

In Rails 2, I used this kind of code to get a certain part of the page
to update.

!-- section/show--
% if @section.has_sidebar %
div id='sidebar_div' class='span-3'
ul class='sidebar_list'
% for page in @section.pages %
li%= link_to_remote #{page.name}, 
:update='show_page', :url
=
{ :controller='pages',:action='show_page', :id=page.id }, :html={}
%/li
hr/
% end %
/ul
/div
% end %
div id='show_page' % if @section.has_sidebar %class='span-18 last
vert_divider'% end %
%= render :partial = 'pages/show', :locals =
{ :page=@page } %
/div

-
In the controller :pages, I had a show_page method that just rendered
the partial again.

In Rails 3, I don't know how to accomplish this.  I want to use
jQuery, which I already know how to code, but I don't know how to get
it working in this way.  Should I create a js.erb file in my view?  I
watched the http://railscasts.com/episodes/205-unobtrusive-javascript
but I still don't know how to get it working to update one part of the
page! Basically, I have this sidebar with links on it, and each time a
user a clicks on one of them, the central part of the page should
update - AJAX!  How do I do this? Do I still need this show_page
method in the controller?

[Rails] Streaming video servers for Ruby on Rails App

2010-11-20 Thread Bharat Ruparel

We have an application that makes heavy use of Videos that need to be
served from a streaming server.  Ideally, this server should be able to
support both quick-time and flash clients (e.g. IPad and Android
tablets).

If anyone has any suggestions based on a product/vendor that has worked
well, please let us know.

Thanks.

2010-11-20 Thread Jose tomas R.

im using
%= button_to 'Rent', :controller = 'transaction' , :action = 'rent',
:id = @product.id %

on ProductsController to pass an :id to a TransactionController

but when searching for the product's id

  def load_product
@product = Product.find(:id).id
  end
i get Couldn't find Product with ID=id Error
i tried using @product = Product.find(1).id for testint an worked, also,
the URL is ok

transaction/rent/1
controller/action/id

BTW, how can i turn that button_to onto a link_to that works with an
action outside self controller

Re: [Rails] Gem environment has wrong ruby version

Hi all,

This appears to be wrong, I'm not sure how to fix it.
Here's my output from gem environment


RubyGems Environment:
 - RUBYGEMS VERSION: 1.3.7
 - RUBY VERSION: 1.8.7 (2010-01-10 patchlevel 249) [x86_64-linux]

- :verbose = true

And here's ruby -v


ruby 1.9.1p0 (2009-01-30 revision 21907) [x86_64-linux]


So gem has the wrong version of ruby in the environment. I suspect  
this

may  be the reason of some weird errors I've been seeing. So how do I
change the gem environment?


You need to install gem (and all your gems) again, under the new ruby.  
Each ruby gets its own gems, stored in its own version tree.

[Rails] Re: Rails2/Rails3 nested form, fields_for not displayed

2010-11-20 Thread Chris Miller

Nicolas,
  Sorry to drag up this old topic, but I'm having the exact same 
problem.  So what was your error?  I assume I'm making the same mistake.

Thanks in advance,
Chris

[Rails] Re: How to get the :remote = true working to update a part of the page?

2010-11-20 Thread daze

I found a clean answer, and I thought I'd explain the solution.
Basically, I was too caught up in the jQuery and etc. - in this case,
Prototype works very nicely.  With jQuery, I got to fumbling around
with a js.erb files.  With prototype, in this, case the solution is
really clean.

http://www.ruby-forum.com/topic/211467 describes a similar solution.

---The View---
!-- section/show --
% if @section.has_sidebar %
div id='sidebar_div' class='span-3'
ul class='sidebar_list'
% for page in @section.pages %
li%= link_to #{page.name}, page, :remote = true 
%/li
hr/
% end %
/ul
/div
% end %
div id='show_page' % if @section.has_sidebar %class='span-18 last
vert_divider'% end %
%= render :partial = 'pages/show_page', :locals = { :page=@page }
%
/div


---PagesController---
class PagesController  ApplicationController

  def show
@page = Page.find(params[:id])
  respond_to do |format|
format.js {
  render(:update) do |page| # uses Prototype, the JS framework
page.replace_html 'show_page', :partial = show_page, :locals
= { :page = @page }
  end
}
end
  end

end

Hopefully this will help anyone who's encountered this same problem,
so that person can come to the answer more quickly.  :D
