ruby on rails - Rails3 and Liquid initialize error -


hi have rails 3 app gem liquid templates. problem error custom tag. using example of wiki.

in /lib/ created random.rb custom tag

 class random < liquid::tag     def initialize(tag_name, max, tokens)      super      @max = max.to_i    end     def render(context)      rand(@max).to_s    end end

in initializers folder liquid.rb register tag.

liquid::template.register_tag('random', random)

in console

@template = liquid::template.parse("{% random 5 %}")

and error:

argumenterror: wrong number of arguments (3 0..1) /users/artau/.rvm/gems/ruby-1.9.3-p385/gems/liquid-2.5.0/lib/liquid/block.rb:28:in `initialize' /users/artau/.rvm/gems/ruby-1.9.3-p385/gems/liquid-2.5.0/lib/liquid/block.rb:28:in `new' /users/artau/.rvm/gems/ruby-1.9.3-p385/gems/liquid-2.5.0/lib/liquid/block.rb:28:in `parse' /users/artau/.rvm/gems/ruby-1.9.3-p385/gems/liquid-2.5.0/lib/liquid/document.rb:5:in `initialize' /users/artau/.rvm/gems/ruby-1.9.3-p385/gems/liquid-2.5.0/lib/liquid/template.rb:58:in `new' /users/artau/.rvm/gems/ruby-1.9.3-p385/gems/liquid-2.5.0/lib/liquid/template.rb:58:in `parse' /users/artau/.rvm/gems/ruby-1.9.3-p385/gems/liquid-2.5.0/lib/liquid/template.rb:46:in `parse' (irb):14 /users/artau/.rvm/gems/ruby-1.9.3-p385/gems/railties-3.2.13/lib/rails/commands/console.rb:47:in `start' /users/artau/.rvm/gems/ruby-1.9.3-p385/gems/railties-3.2.13/lib/rails/commands/console.rb:8:in `start' /users/artau/.rvm/gems/ruby-1.9.3-p385/gems/railties-3.2.13/lib/rails/commands.rb:41:in `<top (required)>' script/rails:6:in `require' script/rails:6:in `<main>'

but if type:

 1.9.3-p385 :004 > @template = liquid::template.parse("{{random 5}}")  => #<liquid::template:0x007fa36b554108 @root=#<liquid::document:0x007fa36b553de8 @nodelist=[#<liquid::variable:0x007fa36b5536e0 @markup="random 5", @name="random", @filters=[]>]>>

and when render:

 1.9.3-p385 :005 > @template.render  => ""

any ideas?

thanks

i'm in rails 3.2.13

try rename class, because in standard ruby library there's class named random .

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
