This commit keeps a stack of lookup contexts on the ActionView::Base
instance. If a format is passed to render, we instantiate a new lookup
context and push it on the stack, that way any child calls to "render"
will use the same format information as the parent. This also isolates
"sibling" calls to render (multiple calls to render in the same
template).
Fixes#35222#34138
This will silence deprecation warnings.
Most of the test can be changed from `render :text` to render `:plain`
or `render :body` right away. However, there are some tests that needed
to be fixed by hand as they actually assert the default Content-Type
returned from `render :body`.
`render :body` should just not set the `Content-Type` header. By
removing the header, it breaks the compatibility with other parts.
After this commit, `render :body` will returns `text/html` content type,
sets by default from `ActionDispatch::Response`, and it will preserve
the overridden content type if you override it.
Fixes#14197, #14238
This partially reverts commit 3047376870.
This is an option for to HTML content with a content type of
`text/html`. This rendering option calls `ERB::Util.html_escape`
internally to escape unsafe HTML string, so you will have to mark your
string as html safe if you have any HTML tag in it.
Please see #12374 for more detail.
This is as an option to render content with a content type of
`text/plain`. This is the preferred option if you are planning to render
a plain text content.
Please see #12374 for more detail.
This is an option for sending a raw content back to browser. Note that
this rendering option will unset the default content type and does not
include "Content-Type" header back in the response.
You should only use this option if you are expecting the "Content-Type"
header to not be set. More information on "Content-Type" header can be
found on RFC 2616, section 7.2.1.
Please see #12374 for more detail.
