ERB help. not seeing variables?

Rails
1

This isn’t for rails specifically… I’m trying to do some ERB
operations…

I’m trying to do some template parsing in a class… here is my class:

require ‘erb’
class TemplateParser
def TemplateParser.parse(template, params)
params.each do |k,v|
self.instance_variable_set(:"@#{k}",v)
end
template_content = ‘’
File.open(template, “r”) do |f|
while line = f.gets
template_content << line
end
end
e = ERB.new(template_content, 0, “%<>”)
e.result
end
end

so in my template… if I have a variable called “revisions”. and it is
set in the params[:revisions] hash. It defines an instance on the class
called revisions, but ERB is not seeing that… What can I do get around
this?

Thanks
