- What's this?
image_alt(src)
public
Returns a string suitable for an HTML image tag alt attribute. The src argument is meant to be an image file path. The method removes the basename of the file path and the digest, if any. It also removes hyphens and underscores from file names and replaces them with spaces, returning a space-separated, titleized string.
Examples
image_alt('rails.png') # => Rails image_alt('hyphenated-file-name.png') # => Hyphenated file name image_alt('underscored_file_name.png') # => Underscored file name
