Ruby templates: How to pass variables into inlined ERB?

Question

I have an ERB template inlined into Ruby code:

require \'erb\'

DATA = {
    :a => \"HELLO\",
    :b => \"WORLD\",
}

template = ERB.new <<-EOF
          


        

Answer 1

Got it!

I create a bindings class

class BindMe
    def initialize(key,val)
        @key=key
        @val=val
    end
    def get_binding
        return binding()
    end
end

and pass an instance to ERB

dataHash.keys.each do |current|
    key = current.to_s
    val = dataHash[key]

    # here, I pass the bindings instance to ERB
    bindMe = BindMe.new(key,val)

    result = template.result(bindMe.get_binding)

    # unnecessary code goes here
end

The .erb template file looks like this:

Key: <%= @key %>
