Your text example doesn't really show how the script you provide works. Here's what you are probably after though - this could be a bit more robust but in this state it's clear:

...

In ruby if you don't know what class an object is you can use it's class method and the docs to find out.


% irb --simple-prompt
>> a = :something
=> :something
>> a.class
=> Symbol

In your controller do you have


@user = User.find(:first)


or something similar? Could you post your controller code?

No problem, its not the most obvious solution

Did your source file definitely have a .rb extension? Did anything at all appear in the output window?

Installed rails? I know its not the be-all and end-all of ruby web development but it is decently documented and probably the easiest way of getting an up and running ruby-based webapp.

Try starting it and navigating to http://localhost:3000

Thanks Ed :)

Looking at your code I can't see whats wrong.

What happens if in your view you do


<% for st in @stocks -%>
<%= h(st.inspect) %><br />
<% end %>

Although your solution is fine it can be a little more readable (and re-usable) in rails.

In the controller:


def banner(text)
span = String.new
text.split(//).each_with_index do |c, i| ...

From my experience using STI isn't too bad so long as too many models are involved; it can get messy using the rails method with the 'type' column.

Of course you could try with CTI but its...

You can add as many :has_many and :belongs_to statements to each model as you like.

Then you can access the associated like this:


#in controller
def view
@actor = Actor.find(1)
end

You should find the method described here (http://www.kanthak.net/opensource/file_column/) suitable. It works for any file type.

Rails wiki on plugins (http://wiki.rubyonrails.org/rails/pages/Plugins)

The params are in a hash (eg {"action"=>"list", "filter"=>"closed", "controller"=>"issue"}. If you want to iterate through them for example use:


params.each do |key, value|
#do something...

params[:param_name]


So say for example you're using pagination and you want the page_number param list?page_number=1:




params[:page_number]

Yeah; you would need to use AJAX to make the form dynamic.

I'm sorry but I disagree, Ruby is very versatile and used an awful lot in non-web applications.

It is Rails that has made Ruby popular as a Web development language
