From bcfbd8ba2192c82aadef6a1d6ba3e87a603ca4f5 Mon Sep 17 00:00:00 2001 From: Matthew Erhard Date: Mon, 28 Sep 2015 18:00:01 -0400 Subject: Fix mounted engine named routes regression When generating the url for a mounted engine through its proxy, the path should be the sum of three parts: 1. Any `SCRIPT_NAME` request header or the value of `ActionDispatch::Routing::RouteSet#relative_url_root`. 2. A prefix (the engine's mounted path). 3. The path of the named route inside the engine. Since commit https://github.com/rails/rails/commit/44ff0313c121f528a68b3bd21d6c7a96f313e3d3, this has been broken. Step 2 has been changed to: 2. A prefix (the value of `ActionDispatch::Routing::RouteSet#relative_url_root` + the engine's mounted path). The value of `ActionDispatch::Routing::RouteSet#relative_url_root` is taken into account in step 1 of the route generation and should be ignored when generating the mounted engine's prefix in step 2. This commit fixes the regression by having `ActionDispatch::Routing::RouteSet#url_for` check `options[:relative_url_root]` before falling back to `ActionDispatch::Routing::RouteSet#relative_url_root`. The prefix generating code then sets `options[:relative_url_root]` to an empty string. This empty string is used instead of `ActionDispatch::Routing::RouteSet#relative_url_root` and avoids the duplicate `relative_url_root` value in the final result. This resolves #20920 and resolves #21459 --- actionpack/CHANGELOG.md | 8 ++++++++ actionpack/lib/action_dispatch/routing/mapper.rb | 1 + actionpack/lib/action_dispatch/routing/route_set.rb | 8 ++++++-- 3 files changed, 15 insertions(+), 2 deletions(-) (limited to 'actionpack') diff --git a/actionpack/CHANGELOG.md b/actionpack/CHANGELOG.md index a0a12f1b0e..a50b81b439 100644 --- a/actionpack/CHANGELOG.md +++ b/actionpack/CHANGELOG.md @@ -1,3 +1,11 @@ +* Fix regression in mounted engine named routes generation for app deployed to + a subdirectory. `relative_url_root` was prepended to the path twice (e.g. + "/subdir/subdir/engine_path" instead of "/subdir/engine_path") + + Fixes #20920.
