Interpolation not working on Rails generator

For some reason the code I have included below does not interpolate the var开发者_运维技巧iables into the template. It simply copies the file over verbatim. I cannot figure out why.

The Rails version is 2.3.4.

Thanks in advance!

Is there NO interpolation going on, or is the interpolation just done with blanks? Reason I ask is, that I think

class <%= @model_name.camelize %>

should be written as

class <%= model_name.camelize %>
