undefined method

Hello Guys,

When i was trying to configure browser cms along with ruby 1.8.7 and rails 2.3.11. It raise the error like `==': undefined method `name' for "abstract":String.

Than i have find the related solution. So follow below things.

Replace method ==(other) at gems/rails-2.3.11/lib/rails/gem_dependency.rb:277

def ==(other)
   if self.respond_to?(:name) && other.respond_to?(:name)
       self.name == other.name && self.requirement == other.requirement
    else
      if other.respond_to?(:requirement)
        self.requirement == other.requirement
      else
        false
      end
    end

end

Hope this will save you life :)

Replace double space with in javascript

Hello Guys,

Last time when i was playing with double spaces.. found the interesting thing. When passing the double space string from javascript (view) to controller , it converts the valid space to non-breaking space.

Lets see the eg.

View: index.rhtml

a = "This is the pen"

a.gsub(" ", " &nsbsp;")

/* Now assign the value to input element by */

$('txtid').value = <%= a %>;

// Get value back encodeURIComponent($('txtid'))

</script>

at controller

def any_method

# replace '\xC2\xA0' or ' ' with ' '

params[:a].gsub("\xC2\xA0", " ").gsub(" ", " ")

end

Hope above article is helpful to you guys.
