After updating to gon 3.0.2 rails helper method not working

[brian-mann]

The rails helper methods: path_to_image and image_path (same thing, 1 is an alias) now return /images/YOURIMAGE.PNG instead of /assets/YOURIMAGE.PNG which is what it's supposed to return.

If I revert to an older version of gon -- say 2.3.0 the helper methods work as intended.

Hello, can you provide a little bit more information about your environment, because on new rails app with gon 3.0.2 and rabl and jbuilder I have normal assets path through helpers:

Gemfile

gem 'rails', '3.2.3'
gem 'rabl'
gem 'jbuilder'
gem 'gon', '3.0.2'

home/index.html.erb

<h1>Hello</h1>
<%= path_to_image('rails.png') %>

result - http://cl.ly/0N422w0R1m3w0v2N231d

Thanks for responding so quickly... I'd be happy to do a bit more testing. I'm actually headed out of town in a few hours so I'll work on this the next time I get the chance.

any updates?

Same issue with gon-5.0.4 and rails-4.0.5.

rails 4.2.4, gon 6.0.1 - same issue

I found that when gon calls for compute_asset_path it not enters in Sprockets::Rails::Helper#compute_asset_path but in ActionView::Helpers::AssetUrlHelper.compute_asset_path.

But when I pointed it to right method, it just not calculates asset_digest_path.

I take a stub at this issue.

Gemfile

  --snip--
gem 'rails', '4.2.4'
gem 'gon', '6.0.1'
  --snip--

views/homes/index.html.erb

<h1>Hello</h1>
<%= compute_asset_path 'rails.png' %>

Below is result.

I think that if you use sprockets, compute_asset_path calls Sprockets::Rails::Helper#compute_asset_path and if you do not use sprockets, compute_asset_path calls ActionView::Helpers::AssetUrlHelper#compute_asset_path.

As I sad when it calls Sprockets it didn't calculate asset_digest_path.
In your stub you use .erb and not gon + jbuilder
