Further simplify the option_html_attributes method after the changes
introduced in dacbcbe55745aa9e5484b10b11f65ccca7db1c54 to not escape the
html options here (since they're going to be escaped down the chain in
content tag).
if nil or an empty array is passed into form_for you get a horrible error message, this one is much more indicative of what the programmer needs to know to fix the problem.
ActionDispatch railtie is a better place for
config.action_dispatch.default_headers settings, users can continue
overriding those settings in their configuration files if needed.
When you mount your application at a path, for example /myapp, server
should set SCRIPT_NAME to /myapp. With such information, rails
application knows that it's mounted at /myapp path and it should generate
routes relative to that path.
Before this patch, rails handled SCRIPT_NAME correctly only for regular
apps, but it failed to do it for mounted engines. The solution was to
hardcode default_url_options[:script_name], which is not the best answer
- it will work only when application is mounted at a fixed path.
This patch fixes the situation by respecting original value of
SCRIPT_NAME when generating application's routes from engine and the
other way round - when you generate engine's routes from application.
This is done by using one of 2 pieces of information in env - current
SCRIPT_NAME or SCRIPT_NAME for a corresponding router. This is because
we have 2 cases to handle:
- generating engine's route from application: in this situation
SCRIPT_NAME is basically SCRIPT_NAME set by the server and it
indicates the place where application is mounted, so we can just pass
it as :original_script_name in url_options. :original_script_name is
used because if we use :script_name, router will ignore generating
prefix for engine
- generating application's route from engine: in this situation we
already lost information about the SCRIPT_NAME that server used. For
example if application is mounted at /myapp and engine is mounted at
/blog, at this point SCRIPT_NAME is equal /myapp/blog. Because of that
we need to keep reference to /myapp SCRIPT_NAME by binding it to the
current router. Later on we can extract it and use when generating url
Please note that starting from now you *should not* use
default_url_options[:script_name] explicitly if your server already
passes correct SCRIPT_NAME to rack env.

Selecting which key extensions to include in active_support/rails
made apparent the systematic usage of Object#in? in the code base.
After some discussion in
5ea6b0df9a
we decided to remove it and use plain Ruby, which seems enough
for this particular idiom.
In this commit the refactor has been made case by case. Sometimes
include? is the natural alternative, others a simple || is the
way you actually spell the condition in your head, others a case
statement seems more appropriate. I have chosen the one I liked
the most in each case.
