params with '.' dot in them

Hi this is my first post on the group and I think its an easy
question.

How do I assign a variable from parameter with a '.' dot in it.
For instance

filename=(params[:Manual.pdf])

Thanks

#2

filename = params['Manual.pdf']

Hope that helps.

#3

filename = params['Manual.pdf']
does not set filename for me. Any other ideas?

Why is the dot in the key?

Why does 'Manual.pdf' look like a value (a real name of a real file)
instead of an abstraction, like :filename?

If Manual.pdf really really is the key, try params[ :'Manual.pdf' ]

Any other ideas?

p params
raise params.inspect

Both of those .inspect the keys, and .inspect generally turns any
"instant value" into its own Ruby expression. That will show you how
to write your :symbol.

Yeah that was my problem, I just mindlessly switched the key with the
value.
