Rails 4 image-path, image-url and asset-url no longer work in SCSS files

Question

Are we supposed to use something else aside from image-url and others in Rails 4? They return different values that don't seem to make sense. If I have logo.png in /app/assets/images/logo.png and I do the following, this is what I get:

image-url("logo.png") -> url("/images/logo.png") #obviously doesn't work image-path("logo.png") -> "/images/logo.png" asset-url("logo.png") -> url("/logo.png") 

Of course none of these work because they need at least /assets in front.

UPDATE: Actually, I just noticed, how do I access images in Rails 4? I have an image at /app/assets/images/logo.png. But if I go to any of the following URLs, I still don't see my image:

http://localhost:3000/assets/logo.png http://localhost:3000/assets/images/logo.png http://localhost:3000/logo.png http://localhost:3000/images/logo.png 

UPDATE 2: The only way I can bring up my logo.png is by moving it into the /app/assets/stylesheets directory and then pulling up:

http://localhost:3000/assets/logo.png 

Answer 1

I just had this issue myself. 3 points that will hopefully help:

• If you place images in your app/assets/images directory, then you should be able to call the image directly with no prefix in the path. ie. image_url('logo.png')
• Depending on where you use the asset will depend on the method. If you are using it as a background-image: property, then your line of code should be background-image: image-url('logo.png'). This works for both less and sass stylesheets. If you are using it inline in the view, then you will need to use the built in image_tag helper in rails to output your image. Once again, no prefixing <%= image_tag 'logo.png' %>
• Lastly, if you are precompiling your assets, run rake assets:precompile to generate your assets, or rake assets:precompile RAILS_ENV=production for production, otherwise, your production environment will not have the fingerprinted assets when loading the page.

Also for those commands in point 3 you will need to prefix them with bundle exec if you are running bundler.
