[Rails] Rails won't execute backticked OS commands
I'm at a loss as what to look for... I can issue a command result = `some_os_command_string` on my dev system just fine in both a pur ruby test file, and from Rails in dev mode. When I push that code to my server, the backtick command doesn't work. No failure message -- even if I wrap it in begin/rescue so I have no specific clues to work from. I can run that same back ticked command on the server from a simple ruby test file, but not from Rails. Any ideas what I could look for as to why Rails might be interfering with this?

[Rails] Multiple classes on form text_field
Consider :
- - - -
<% form_for(@z) do |f| %>
<%= f.error_messages %>
<%= f.label :x %>
<%= f.text_field :x, :class => 's' %>
<%= f.submit 'Update' %>
<% end %>
- - - -
The above form works fine. What I want to do is have two classes, s and
t, associated with text_field :x.
The following does not work.
- - - -
<% form_for(@z) do |f| %>
<%= f.error_messages %>
<%= f.label :x %>
<%= f.text_field :x, :class => {'s', 't'} %>
<%= f.submit 'Update' %>
<% end %>
- - - -
The code above will generate a single class class="st"
How can I have two classes in the same field using form helper? Do I
have to generate my own html?

You want awesome_nested_set, which will let you do that with one query.

I would not recommend using single quotations over double. One argument
against using single quotes is that you will not be able to embed ruby
code into your link:
"A link to a #{link_to("website", "http://ruby-forum.com";)}"
If you want consistency, consistently use double quotations.

[Rails] Re: Mac and Rails
There are some wonderful guides out there for this. Rails works great out-of-the-box on OS X. Out of the editors I've used, I believe textmate is the best. It's visually pleasing and very extensible. It also is the text editor seen in the famous "Rails Casts" from 37Signals. http://macromates.com/ I use Textmate in combination with Panic's Transmit ftp software (http://www.panic.com/transmit/) and Firefox armed with Firebug as my environment. I find it highly productive. (I love textmate and it seems to be one of the posterchild editors for Rails, but it will take some time to get used to. It has a lot of great features) You have a few options for your Rails installation... The absolute easiest is just to update the Rails app installed with OS X. You'll be up and running in just a few minutes: http://wiki.rubyonrails.org/getting-started/installation/mac If you don't want that, consider the RubyStack from BitNami: http://bitnami.org/stack/rubystack For maximum control, you can manually build Rails, as well: http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard Lastly, I've not needed to use a particular version of Rails so far, but I believe you can install older versions of rails as Gems, if you need them. See this article: http://www.nomachetejuggling.com/2008/03/12/using-multiple-versions-of-rails/ Hope that helps a little.

Not to worry about this as I'm happy where I'm going. Logically it's not a
huge problem, getting it Rubyish might be ;) Long time Perl programmer.
Thanks for the links, I'd already seen the second link.
Thanks for the bit about the fractions, it's given me something to think
about but from what I can see, they will still have to be tacked on to the
decimal. The decimals were done the way you suggested but now they're just
in a loop (more flexible) as time_units may well be added in the future.
I don't want to labour on this so I'll just do what I was going to do.
Again, thanks.

To be honest, I don't really understand what you're asking for help
with. If you can state your position in different terms, because what
you've said so far obviously hasn't clicked with anyone (or at least
we've clicked the same, wrong, way! ;-)
Feeling around in the dark a little:
http://snippets.dzone.com/posts/show/1137
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/170729
The code you posted does look a little smelly. I don't know why you're
turning your numbers into strings and then back into numbers again.
For instance, where you say " ## need validation (can't have hundtedth
without tenth, for example)", I think you could ignore if you just
approach adding up the seconds differently.
So for instance if :
time_units = {:seconds => 22, :hundredths => 0, :milliseconds => 8}
you can just do the arithmetic:
fraction = 0
fraction += time_units[:tenths] * .1 if time_units.has_key?(:tenths)
fraction += time_units[:hundredths] * .01 if time_units.has_key?(:hundredths)
fraction += time_units[:milliseconds] *.001 if
time_units.has_key?(:milliseconds)
should result in 0.008
Frankly, stuff the fraction variable. Treat @decimal_time the same:
@decimal_time += time_units[:seconds] if time_units.has_key?(:seconds)
@decimal_time += time_units[:minutes] * 60 if time_units.has_key?(:minutes)
@decimal_time += time_units[:hours] * 3600 if time_units.has_key?(:hours)
@decimal_time += time_units[:milliseconds] *.001 if
time_units.has_key?(:milliseconds)

[Rails] Re: Rails 3 link_to :remote
Update for anyone that needs help in this area. I found my problem. You
might have to do the same (if you are using this function the way I am).
In my controller, I don't know why I put this in the Index action
before. It is now in the SHOW (duh) action:
format.js {
render(:update) {|page| page.replace_html 'order_div', :partial =>
'orders/order_show'}
}
I took out all of the other junk in my "link_to" in the view and only
have this now:
<%= link_to "#{order.name}", order, :remote => true %>
So I have a list of orders in a column on the left side of the screen.
There is a right border separating it and the right column. When I click
on one of the orders, it shows the order info in the right column.
Exactly what I wanted. Piece of cake now that I think about it.
Enjoy!

[Rails] Re: Building a Cascading Drop Down Selection List for Ruby on Rails with jQuery Ajax
Easiest would be to make the select a partial and update the partial based on the object sent to the query.

OK, so you have an array of times. You sort through them based on: (predicted_time - actual_time).abs and pick the smallest 10 items.

I don't have a problem with comparing floats, but I might need to find the
10 closest times to the actual event time and 4 of those times could be less
than the actual event time and 6 could be higher.
I don't mind rolling my own and am quite looking forward to it, but I don't
want to re-invent the proverbial wheel.
FWIW, here's the conversion code to convert integer values to their
respective seconds.
@@time_constants = {:years => YEAR,
:months => MONTH,
:weeks => WEEK,
:days => DAY,
:hours => HOUR,
:mins => MIN }
def to_decimal(time_units={})
raise ArgumentError if time_units.empty?
time_units.each_pair do |key, value|
## skip seconds and fractions thereof
next unless @@time_constants.has_key?(key)
## convert integer time units into seconds
@decimal_time += @@time_constants[key] * value
end
## whack on the seconds
@decimal_time += time_units[:secs] if time_units.has_key?(:secs)
## need validation (can't have hundtedth without tenth, for example)
fraction = ''
fraction = '.' + time_units[:tenth].to_s if
time_units.has_key?(:tenth)
fraction << time_units[:hundredth].to_s if
time_units.has_key?(:hundredth)
fraction << time_units[:millisecond].to_s if
time_units.has_key?(:millisecond)
## concat fraction string to @decimal_time, convert to float for DB
@decimal_time = (@decimal_time.to_s << fraction).to_f

[Rails] Off Topic Advice Needed (Time objects)
I know this is a Ruby question but I'm not on any Ruby mailing lists and it's for a Rails project (so might come under select_time etc. ;) ) I thought I'd try here. A user can choose integer values from select drop down boxes to predict how long an event will take. Obvious values are secs (0-59), minutes (0-59) weeks (0-4), months (0-11) ... These values are then converted to seconds and stored as decimal in the DB (I allow fractions of a second, too (tenth, hundredth, millisecond). when they are retrieved form the DB, I convert the seconds to a string format of, for example, 01:39:11 (from 5951 seconds). If fractions are used, they are just appended to the string. (non of this is elegant IMO) That's all done in my Converter class. I am going to write a Calculator class to compare all times entered for an event and picking the closest times to how long the actual event took. So my question is, I know I can't use a Time object but it would be really nice to know if there is something out there that could help me with this as to write my own Calculator is going to be a bit of a pain. Also, by throwing this out there, somebody might say something that I haven't thought of doing and could totally change the way I'm doing this.

Firstly, I'd query why there has been a choice of any technology platform without anyone of experience to decide? Normally, I'd expect the CTOs platform of experience is what's plumbed for.

In Scotland, you might try to ask at http://rubaidh.com/company - although they may not be inclined to respond if you're starting a competitor! In the rest of the UK there does seem to be a fair spread of us, but it is a small pool. > If a CS grad, is it difficult to pick up - how long would you think it > takes to become proficient? Very few people I have met are straight to Ruby/RoR from uni. The majority have arrived after a period of their career and are thus quite senior. As far as CS grads (or self-taught techies) are concerned, you may find yourself in the position of having to teach them everything - even re-teach a some of what they've covered in their courses - from HTML, CSS upwards. But on the flip side (and I worked with one guy like this) very bright people *can* pick stuff up very quickly. > Thanks in advance for any insights shared.

Re: [Rails] Ruby on Rails Analyst/Programmers, Glasgow.
"If a CS grad, is it difficult to pick up - how long would you think it takes to become proficient?" It will be very difficult if you are just a CS grad. ROR is a framework of whole set of web technologies. So, it will be very difficult to master it in less than 6 months. You need a strong web development technical leader with reasonable ROR expertise for atleast a year. CS graduates dont get educated with open source technologies. They usually come up with Java background. If you get graduates with PHP background and who have self-learnt Ruby languages, you are lucky. Put an advertisement in ROR job sites, eg jobs.rubynow.comand see how many are turning from Glasgow. On 16 June 2010 11:37, Deirdre Shell wrote: > Hi All, > > I would like your advice.

This includes hosting, of course. RoR already has an extensive community and a growing API, with support from major banking bodies and other industry-specific experts.

Hi All, I would like your advice. I'm helping a young company set up a ROR team from entry level to Senior A/P. I've not worked with this tech before so have some basic questions. What are your thoughts: Is this a well exploited technology in Scotland/UK? What's the typical career path for an RoR A/P ( from a PHP background or other)? If a CS grad, is it difficult to pick up - how long would you think it takes to become proficient? Thanks in advance for any insights shared.

[Rails] Field validation
Hi
I have a field called "cost":
<%= f.text_field :cost, :size=>2, :maxlength=>4 %>
I want to check that user enter numeral value and this value is integer
In post.rb (model):
def cost_validate_int
errors.add_to_base("Error message") unless cost.is_a?(Fixnum)
puts "### #{cost}: "+cost.class.to_s
end
When I enter in field 100 I get:
### 100: Fixnum
when I enter 10.1:
### 10: Fixnum
when I enter 'asdf':
### 0: Fixnum
I completely can't understand what happen. In migration:
t.integer :cost
I think ActiveRectord converts value to Fixnum because in migration this
field signed as integer
Can I in some way check cost value in model (value should be numeral and
integer)?
Thanks in advance!

user has many contact and if it is nested you can use simply
form_tag([...@user,@contact])
It will works for creating contact under index action
In controller create @contact = @user.contacts.new
Try This,

[Rails] modifying an association during inheritance
I have a Team class that inherits from a Group class. Both Team and Groups have memberships through the same association. However, I need to run a method after a Team memberships is added but not a Group. I currently have something like this: class Group < ActiveRecord::Base has_many :memberships, :class_name => 'Connection', :foreign_key => 'connectable_id', :as => :connectable, :dependent => :destroy end class Team < Group has_many :memberships, :class_name => 'Connection', :foreign_key => 'connectable_id', :as => :connectable, :dependent => :destroy, :after_add => :add_company_membership private def membership_check(membership) end end Is there some way to modify the inherited association in Team so that I don't have to redefine the entire thing but rather just add the :after_add hook it?
