ERB question, not seeing variables..

[Aaron Smith]

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

e.result

I'm not sure if it will be helpful in your situation, but e.result
will accept a binding parameter. That binding is used to resolve local
variables in the template.

File.open(template, "r") do |f|
while line = f.gets
template_content << line
end
end
e = ERB.new(template_content, 0, "%<>")
e.result(self.send("binding"))
end
