RMagick at dreamhost

I’m getting the crazy error “undefined method `resize_to_fit’ for
#Magick::Image:0x41b74904

I have RMagick on dreamhost, but no resize_to_fit method? Am I missing
something?

You may be missing a sufficiently recent version of RMagick. The
resize_to_fit method was added in version 1.11.0. What version of
RMagick is installed? Try this:

ruby -r RMagick -e"puts Magick::Long_version"

If the version is older than 1.11.0, you can add it yourself. The
Image#resize_to_fit method is extremely simple to write. The code for it
in RMagick.rb is this:

def resize_to_fit(cols, rows)
    change_geometry(Geometry.new(cols, rows)) do |ncols, nrows|
        resize(ncols, nrows)
    end
end

Indeed on my host (clamato.dreamhost.com) I have Rmagick 1.6.0, a 2004
build.

This is my first public rails website and I’m still learning. Your
solution was perfect. I just added this on top of my model.rb. It needed
a small modification, so I’m posting this here, maybe to help another
newbie.

quick hack for dreamhost for an old version of RMagick

class Magick::Image
def resize_to_fit!(cols, rows)
change_geometry(Magick::Geometry.new(cols, rows)) do |ncols, nrows|
resize!(ncols, nrows)
end
end

def resize_to_fit(cols, rows)
change_geometry(Magick::Geometry.new(cols, rows)) do |ncols, nrows|
resize(ncols, nrows)
end
end
end
