Excerpt
Is there any way to ask the Asset Pipeline if an asset exists? The suggestions I largely see involve manually checking the file path with File.exist?. The problem with that is that I have several gems that include assets, so I would have to look at the assets directories for each of those, right? This seems like something I would expect to be baked into the Asset Pipeline, but I can't find any reference to it.
My current solution is an ugly hack, so I hope you have something better. Calling asset_path(file) will either return a new URL (/asset/xyz) for an asset or the same path if it does not exists (or if it's an absolute path). So my ugly hack is:
def has_asset?(path)
# Asset pipeline only does relative paths
if path[0] == '/'
return false
end
asset_path(path) != '/#{path}'
end
