Better still is:

code:

nicks = members.map(&:nickname)

drat, now I really wish I could come, especially since I have a developer here thats learning the ropes on Ruby and Rails after years of PHP and this would be some good experience. Unfortunately that developer is the owner of the farm we're all paintballing at.

Its also a bit of a drive as we're all pretty far out in the countryside. Rural Ontario Ruby developers

Any idea if 3.1 is going to be dramatically different than 3.0? I'm in the same boat and just to see how bad things were I upgraded one of our 2.3.11 apps yesterday and it was oddly painless. I think I changed one or two lines of code but everything just worked. I was kind of expecting apocalyptic app failure across the board but it doesn't look like all that much changed in the core MVC parts of rails.

So I tried creating my own validation. I know it's ugly but please forgive me!

code:

	validates :cant_have_more_than_one_guard

	def cant_have_more_than_one_guard
		total_guards = 0
		members.each do |member|
			if member.gen_pos == 'Guard'
				total_guards = total_guards + 1
			end
		end
		unless total_guards <= 1
			errors.add_to_base "Can't have more than 1 guard"
			return false
		end
	end

When I try to load the team view, I get the following error:

code:

ArgumentError in MembersController#create

You need to supply at least one validation

Not sure where to go from here. I guess I don't really have experience using validations when they're not for some sort of form. Do I need to put this within the method I'm calling from the TeamsController? I tried this as well and Rails didn't know what validates is so I'm assuming that's not the right way...

Thanks again for your help!

Edit: yeah it's Sinatra and not Rails, deal with it

code:

def cant_have_more_than_one_guard
  guards = members.select { |m| m.gen_pos == 'Guard' }
  errors.add_to_base "Can't have more than 1 guard" unless guards.count <= 1
end

Here is some less ugly code. I am too tired to figure out the validation thing though.

I usually use web: bundle exec thin start -p $PORT, then it grabs the config.ru

My fault. See http://api.rubyonrails.org/classes/ActiveModel/Validations/ClassMethods.html#method-i-validate - you want validate, not validates, which is used for something completely different.

I'm looking to further my skills and develop some database intensive sites. I'm new to Ruby, PHP, and SQL but have significant experience with HTML and CSS. How should I proceed? Will learning Ruby teach me what I need to know about PHP and SQL, or should I learn the basics of PHP and SQL and then transition smoothly to Ruby?

Sorry for the amateurish question but I'm just looking for some expert opinions.

So I tried using validate and the error went away, but no errors ever pop up.

Here's my memberscontroller:

code:

  # POST /members
  # POST /members.xml
  def create
    @team = current_team
  	player = Player.find(params[:player_id])
  	@member = @team.add_player(player.id)

  	respond_to do |format|
  	  if @member.save
    		format.html { redirect_to(@team, :notice => 'Member was successfully added.') }
        format.js { @current_member = @member }
    		format.xml  { render :xml => @member, 
  			:status => :created, :location => @member }	
  	  else
    		format.html { redirect_to(@team, :notice => @team.errors.full_messages) }
    		format.xml  { render :xml => @member.errors, 
  			:status => :unprocessable_entity }
  	  end
    end
  end

Doesn't seem like the validation is doing anything. When I change it to unless 2 > 1, the create member action still goes through and there's no error displayed. What am I doing wrong?

sounds like you're using rails 2. "rails new" is a rails 3 command. "rails /path/to/myapp/" is the rails 2 command. type "rails -v" to see what's up.

Guys this problem is stressing me out.

I installed Ruby, Rubygems and Rails the way "Agile Web Development with Rails" tells me to, but whenever I write something like "rails new demo", it creates a folder named new with, what I suppose are, the usual Rails files.

The thing is, it happens every time I write "rails". I wrote "rails server" and it only created a folder named server with the exact same files as before.

Any solution?

Make sure you're using the 4th edition of Agile Web Development with Rails if you're working in Rails 3.x, and the 3rd edition if you're working with 2.2 or 2.3

1.8 or 1.9?
If you're using 1.8 you want to use REE

kalleth posted:

Can I see the validate code from the model as well? Are you sure the create action still goes through; I.e. is something being persisted to the database? Perhaps call save! rather than save which will create an exception if the save fails?

A good way of debugging stuff is using the $ rails console command line to give you effectively an irb within your app environment.

This will let you do something like

> team = Team.find(:first)
#<Team:Object>
> team.add_player(Player.find(:first))
#<Team:Object player=#<Player:Object>>
> team.save!
> either backtrace or false or true

You can then use the console to inspect any errors.

My application serves profile images and I don't want any schlub who knows the URL for the image to be able to load it. That part is easy, I control access in Photos#show and use send_data (photos are stored in the DB btw). However it looks like browsers aren't caching the photos, which makes page load times unnecessarily long. This feels like a stupidly basic question, but what should I do here to speed up loads? Is there any way I can provide an etag before the controller method is invoked and I have to deal with the database hit?
