[Rails] Why does rendered.should have_field pass when it shouldn't?

[David Zhang]

This is my new.html.erb_spec.rb:

  let(:meal) do
mock_model("Meal").as_new_record.as_null_object
  end
  
  before(:each) do
assign(:meal, meal)
  end

  it "shows the name text field" do
  render
  rendered.should have_field(:name) # checks for both the label and the 
text field... right?
end

it "shows the description text area" do
  pending "This passes when it shouldn't"
  render
  rendered.should have_field(:description) # have_field is for text 
fields and text areas (w/labels)... right?
end

it "shows the ingredients text area" do
  pending "This passes when it shouldn't"
  render
  rendered.should have_field(:ingredients)
end

==
This is my new.html.erb:


New Meal
<%= render :partial => "form", :locals => { :meal => @meal, :button_name => 
"Create" } %>

It renders this partial...
==
The partial - _form.html.erb

<%= form_for [:admin, meal] do |f| %>
<%= f.label :name %>
<%= f.text_field :name %>
 
 <%= f.submit button_name %>
<% end %>

=


The problem: rendered.should have_field(:description) and the one for 
ingredients are passing although I never specify the description / 
ingredient text fields or textareas in the form.  Why is this?  It seems 
that the presence of the label and text field for :name is enough to make 
any have_field pass...

(have_field DOES test for text fields or text areas, right?)
(why does the documentation basically tell you /nothing/? no example or 
anything 
http://rubydoc.info/github/jnicklas/capybara/master/Capybara/RSpecMatchers#have_field-instance_method)

Help would be greatly appreciated.

Re: [Rails] Does the asset pipeline (RoR 3.1) waste cycles?

[Dieter Lunn]

In a development environment it recompiles the assets on every
request. When in production it does it once and adds a hash to the
filename for caching.

[Rails] when to add validations to database

[Adrian Caceres]

Normally all my validation is done in my models.

Michael Hart in his rails tutorial explains why the uniqueness 
validation should also be done at the database layer ( 
http://ruby.railstutorial.org/chapters/modeling-and-viewing-users-one#sec:the_caveat).


I am curious if people have experienced other validations that should 
also be done at the database layer?


thanks

[Rails] Does the asset pipeline (RoR 3.1) waste cycles?

[Jeff Pickhardt]

With the Ruby on Rails asset pipeline in RoR 3.1, it's unclear if the
.coffee and the //= require files get processed only once or with each asset
request.

For example, I have a file that looks like this:

//= require source/main.js.coffee
//= require source/second.js.coffee
//= require source/third.js.coffee

Ideally, the server would compile these to js ONCE, then bundle them, then
create a static file.  Otherwise it's going to be wasting cycles repeating
effort.

Can someone clarify what happens?

Thanks,
Jeff

My guess would be that 'current working directory' doesn't mean the
same thing to a daemonized process; how are you specifying the target
directory? Regardless...

> Also the reason I want to run in Daemon mode is ...

Why Webrick? It's only intended for desktop development work; you
would be better off using e.g. unicorn (my preference) or passenger
in a production environment.

Alternatively, if those aren't an option, see if you have `screen` on the
system you're using (http://www.gnu.org/software/screen/).

[Rails] Web services - json-rcp

[Marketlija Pik]

Hello.


I am starting to write a web services in RoR, and considering different 
technologies to use. I am wondering if someone had experience working with 
json-rcp and what are its (dis)advandages over SOAP and REST.


Thank you,
Derek

[Rails] Can't upload files when WEBrick running in daemon mode.

[Jen]

Hi,
When running my app in development with WEBrick in daemon mode I get the 
following error when trying to upload a file:



 Errno::ENOENT in UploadController#create

No such file or directory - public/data/upload/google

|Rails.root: /home/resource_portal/website|

Application Trace  | Framework Trace 
 | Full Trace 



|app/models/upload.rb:29:in `initialize'
app/models/upload.rb:29:in `open'
app/models/upload.rb:29:in `filesave'
app/controllers/upload_controller.rb:16:in `create'
rake-0.8.7/ruby/1.9.1/gems/actionpack-3.0.3/lib/action_controller/metal/implicit_render.rb:4:in
 `send_action'
rake-0.8.7/ruby/1.9.1/gems/actionpack-3.0.3/lib/abstract_controller/base.rb:151:in
 `process_action'|
...

I do not get this error when not running in daemon mode. I've googled a bit but 
can't find a reason. Does anyone have any ideas?

Also the reason I want to run in Daemon mode is because I have to host my app 
on a uni virtual machine, and start the server after logging in with ssh. When 
I close the ssh connection the server (if not running in background) also seems 
to get killed.

Any ideas as to how I may be able to work around this?

Thanks,
Jen.

[Rails] Re: displaying attribute from related table with a collection_select

Well that was easy! After a little trial and error, I created a new
