Ditto - total lifesaver! However, On ActiveAdmin 1.2.1, this gives an error:
ActionView::Template::Error (Can't be in the context of nil. [, <!DOCTYPE html><html lang="en">
You'll have to prepend to #build_active_admin_head and #build_body instead of directly to #build.
In my use case, I wanted to prepend a partial BEFORE the ActiveAdmin masthead/page header, so I did this:
module AdminPageLayoutOverride
def build_page(*args)
within @body do
render "layouts/global/environment_banner"
end
super
end
end
ActiveAdmin::Views::Pages::Base.send :prepend, AdminPageLayoutOverride
Here's the relevant class we're patching:
https://github.com/activeadmin/activeadmin/blob/1-2-stable/lib/active_admin/views/pages/base.rb
If you're on another version of the gem, you can look at the version from that branch to figure out your exact patching strategy.
Thanks all! This was helpful.
In Active Admin 1.4.3, it's like this:
module AdminPageLayoutOverride
def build_page(*args)
within body(class: body_classes) do
render partial: 'layouts/global/environment_banner'
end
super
end
end
ActiveAdmin::Views::Pages::Base.send :prepend, AdminPageLayoutOverrideReference:
https://github.com/activeadmin/activeadmin/blob/v1.4.3/lib/active_admin/views/pages/base.rb#L48
Is there a way to do this now in AA 2.7?
This approach gives me:
ActionView::Template::Error:
Can't be in the context of nil. [, <!DOCTYPE html><html lang="en">
... because @head is nil when this is evaluated. Same thing occurs with super at the end of the method too.
Actually, answered this myself based upon the source: just replace @head with head and @body with body, and you're off to the races.
module AdminPageLayoutOverride
def build_active_admin_head
super
# this will be added at the end of <head>
within head do
text_node(javascript_pack_tag("application"))
end
end
end
ActiveAdmin::Views::Pages::Base.send :prepend, AdminPageLayoutOverride
This worked for me in AA 2.2. But I noticed that it adds two head tags. Any clue on how to fix it?
LOL - I just looked at the HTML in AA 2.7, and found the JS and CSS tags in the <body>. Only one <head> though.
It works correctly if you put the super at the end instead of the beginning:
module AdminPageLayoutOverride
def build(*args)
# This will be added at the beginning of <head>
within head do
# stuff here
end
# This will be added at the beginning of <body>
# within body do
# end
super
end
end
ActiveAdmin::Views::Pages::Base.prepend(AdminPageLayoutOverride)That being said, I think the recommended way to do this now is via the # Register Stylesheets & Javascripts section of the active_admin.rb initializer.
If you don't have that section (I didn't), then assuming your codebase is in a repo, you can rerun the AA generator to get the updated initializer, skipping everything you can except the initializer generation, reverting everything except the initializer changes, and then using the diff to decide what to revert in the initializer. (There may be a better procedure than that, but that does work.)
Note that the above didn't work for me on AA 2.7, but this comment did: activeadmin/activeadmin#5201 (comment)

That worked. Thanks @tobycox.
Thanks. I was finally able to change AA color, even though we're using the same build to deploy to multiple environments
def build_active_admin_head
within super do
text_node("<style>:root {--primary-color: #{Rails.env.production? ? '#ff8b41' : '#505050'};}</style>".html_safe)
end
end
You are life saver! Thanks!
