Question

I have a ruby script for a photo with a link to its url:

<%= if property.images[0] then link_to image_tag (property.images[0].image.url('350x263', :jpg)), user_property_image_path(user, :id => property.images[0], :property_id => property) end -%>

How do I append #gallery to the end of the URL?

Answer 1

Try this (broken into multiple lines for clarity):

link_to(
  image_tag(property.images[0].image.url('350x263', :jpg)),
  user_property_image_path(user,
    :id => property.images[0],
    :property_id => property,
    :anchor => "gallery"
  )
)

The key bit is :anchor => "gallery". #url_for will recognize this and append it to the URL as a URL fragment.

See the documentation on url_for for a full list of available options.
