Configure Avo's app-wide admin settings in config/initializers/avo.rb via Avo.configure — app name, timezone/currency, per-page and index behavior, layout width, home redirect, open-in-editor links, and the other global knobs that don't belong to a single feature. Use when the user wants to change how many records per page, rename the admin / change the app name, set the timezone or currency for the admin, default the index to grid view, make the admin full-width, keep clicking a row from opening the record, skip the show view / go straight to edit, open Avo files in Cursor or VS Code from the UI, keep the sidebar always open, redirect the admin home to a dashboard, add a class to the body tag, make rows denser, widen the sidebar or turn off sidebar resizing, persist filters/pagination across requests, or opt out of usage metadata.

Avo Admin Configuration
Avo's initializer, config/initializers/avo.rb, holds the app-wide settings that don't belong to any one feature — the app name, timezone, per-page count, index behavior, layout widths, the home redirect, the open-in-editor links, logging, and so on. They're all set inside a single Avo.configure do |config| block by assigning to config.<name>:
A handful of these have resource-level equivalents — set them globally here, or override per resource as a class attribute (self.default_view_type, self.pagination, self.density on dashboard cards). With no configuration at all, Avo computes the app name from your Rails app, uses UTC/USD, shows 24 records per page in constrained-width tables, and redirects the logo to your first resource.
This skill is partly a router. It owns only the genuinely-global knobs. For anything that belongs to a specific feature, hand off to its skill instead of duplicating it here:
Installing, mounting (root_path, prefix_path), and the license key → avo-setup
Authorization client and policy wiring → avo-authorization
Docs
Authoritative docs — fetch on demand rather than guessing, and verify every option name against the docs or the app's installed Avo source before writing it:
Explicit (Avo named): "set config.app_name", "change per_page in the Avo initializer", "set default_view_type to :grid", "use container_width = :full", "set resource_default_view = :edit", "configure default_editor_url", "enable persistence", "set body_classes".
Implicit (Rails-shaped, no mention of Avo): "change how many records show per page in the admin", "rename the admin / change the app name in the top bar", "set the timezone/currency the admin displays", "default the admin list to grid/card view", "make the admin full-width", "clicking a row shouldn't open the record", "skip the show page and go straight to edit", "open the admin's source files in Cursor/VS Code from the UI", "keep the sidebar always open / hide the collapse button", "make the sidebar wider by default", "stop people resizing the sidebar", "send people to a dashboard when they open the admin", "add a CSS class to the <body> tag", "make the admin rows denser / tighter", "keep my filters and pagination when I navigate away", "stop the admin from phoning home usage stats".
Common settings
Every option below is a config.<name> assignment inside Avo.configure. Most accept a literal value or a block/proc evaluated per request (useful for I18n lookups or per-user logic).
Naming and locale
config.app_name = "Avocadelicious"# navbar label next to the logo
config.app_name = -> { I18n.t "app_name" } # block form for dynamic/i18n names
config.timezone = "UTC"# for date/datetime fields
config.currency = "USD"# for currency fields
config.locale = "en-US"# force Avo's UI locale (default: I18n.default_locale)
app_name defaults to the humanized Rails application class name. To replace the single app-name link with a list of navbar links, that's the header menu → avo-navigation-search.
Index view behavior
config.per_page = 24# default page size (default 24)
config.per_page_steps = [12, 24, 48, 72] # options in the per-page picker
config.via_per_page = 8# page size inside has_many association tables
config.default_view_type = :grid# :table (default), :grid, :map, or a custom view type
config.first_sorting_option = :asc# direction on first sort click (default :desc)
config.density = :tight# row height: :tight, :normal (default), :relaxed
config.field_wrapper_layout = :stacked# label above value everywhere (default :inline)
config.click_row_to_view_record = false# stop the whole row linking to Show (default true)
config.id_links_to_resource = true# render id fields as links to the record (default false)
config.cache_resources_on_index_view = false# disable per-row index caching (default true)
config.search_debounce = 300# ms to wait after typing before searching (default 300)
config.pagination = { type::countless } # global pagination defaults; same keys as self.pagination
default_view_type, pagination, and density (on dashboard cards) also exist as per-resource class attributes — set globally here, override per resource. Row-control placement (resource_row_controls_config) lives on the table-view docs.
Layout
config.container_width = :full# one width for all views
config.container_width = { index::full, show::small } # or per view / group alias
config.sidebar = { # the sidebar's three knobs, merged over the defaultstoggle_visible:false, # hide the collapse button → sidebar stays open on desktop (default true)resizable:false, # remove the drag-to-resize handle (default true)default_width:320# px the sidebar starts at before a user drags it (default 256)
}
config.hide_layout_when_printing = true# drop sidebar/navbar/footer when printing
config.body_classes = "custom-theme compact-layout"# add classes to <body>; also accepts an Array or a block
config.sidebar is a hash merged over {toggle_visible: true, resizable: true, default_width: 256}, so set only the keys you change. On desktop the sidebar edge is a drag handle: users resize it and the width persists per browser (a cookie, not a user preference). default_width sets the starting width and is clamped to 200–480 — an unparseable value falls back to 256 rather than clamping to the minimum. Both settings apply at lg (1024px) and wider only; below that the sidebar is a full-height overlay at the 256px default. A width the user has dragged to wins over default_width. The flat config.sidebar_toggle_visible = false still works and writes into config.sidebar[:toggle_visible], but the hash is the canonical home.
container_width values are :large (default index), :small (default show/forms), and :full. The hash form accepts individual views (:index, :show, :new, :edit, :create, :update) and group aliases (:forms, :display, :single); a specific key wins over an alias. The body_classes block runs in Avo's ExecutionContext, so it has current_user, request, and params.
Navigation home and record flow
config.home_path = "/avo/dashboard"# where the logo / "/avo" redirects
config.home_path = -> { avo_dashboards.dashboard_path(:dashy) } # block form has route helpers
config.resource_default_view = :edit# skip the Show view; go straight to Edit
config.alert_dismiss_time = 8000# ms before flash alerts auto-dismiss (default 5000)
Pair home_path with set_initial_breadcrumbs for a cohesive landing (breadcrumbs detail → avo-navigation-search). Setting home_path also hides the development-only "Get started" sidebar item.
Editor and development
config.default_editor_url = "vscode://file/%{path}"# the </> "open in editor" links (dev only)
config.view_component_path = "app/frontend/components"# where generated field view_components land
config.model_generator_hook = false# stop `rails g model` from also generating an Avo resource
In development, Avo renders a small </> icon next to resources, actions, filters, dashboards, cards, and forms; clicking it opens that class's source file via default_editor_url, where %{path} is the absolute file path. It defaults to Cursor (cursor://file/%{path}) — switch the scheme for VS Code (vscode://file/%{path}), Sublime (subl://open?url=file://%{path}), etc.
Other global knobs
config.set_context do# attach a payload to the global `context` object
{ params: request.params }
end
config.persistence = { driver::session } # keep association pagination + static filters across requests
config.associations = { # global association defaults (set only what you change)lookup_list_limit:1000,
frames: { loading::lazy, auto_load_for:15.minutes }
}
config.turbo = -> { { instant_click:true } } # Turbo behavior inside Avo
config.default_url_options = [:account_id] # params appended to every generated path (route multitenancy)
config.logger = -> { ActiveSupport::Logger.new(Rails.root.join("log", "avo.log")) }
config.exclude_from_status = ["license_key", "ip"] # items hidden on /avo_private/status (license_key hidden by default)
config.send_metadata = false# opt out of usage metadata (Community licenses only)
Gotchas
container_width replaces the Avo-3 booleans.config.full_width_container = true → config.container_width = :full; config.full_width_index_view = true → config.container_width = { index: :full }; full_width_container = false → just remove the line. It raises ArgumentError on an unknown width or hash key.
resource_default_view replaces skip_show_view. The old config.skip_show_view = true is now config.resource_default_view = :edit (default :show). This retargets row links, post-create/update redirects, and association links to Edit.
persistence: { driver: :session } can overflow the cookie store. Rails' default cookie session store is capped at 4096 bytes; many stored pagination + filter states raise ActionDispatch::Cookies::CookieOverflow. Move to a scalable session store (Redis, Memcache) before enabling it broadly.
default_editor_url defaults to Cursor. If a user's </> icons open Cursor unexpectedly, that's the default — point it at their editor. The icons only render in development.
Disable cache_resources_on_index_view when fields vary by role. The index cache key uses the record's id/created_at and the resource file md5 — not the current user — so a resource that shows/hides fields per role (visibility:) will serve one user's row layout to another. Turn it off there. For the caching model and cache store, see avo-performance; for role-based field visibility, see avo-authorization.
Sidebar resizing is a drag-only gesture. It doesn't satisfy WCAG 2.2 SC 2.5.7 (Dragging Movements), so an app working to an AA conformance claim or a VPAT should set config.sidebar = {resizable: false}. Related: sidebar labels now truncate with an ellipsis (plus a hover tooltip) instead of wrapping — if a menu relied on long labels wrapping, shorten them or widen the sidebar.
click_row_to_view_record is JS-enhanced. Making a <tr> behave as a link isn't native HTML; Avo does it with JavaScript, which can have side effects. Disabling it (false) reserves navigation for the explicit row controls.
Verify before writing. Option names and defaults drift between versions and several were renamed in Avo 4 — check the docs URLs above or the app's installed lib/avo/configuration.rb rather than trusting memory.
Report
When done, tell the user:
The exact config.<name> lines you added or changed in config/initializers/avo.rb, and what each does.
Any Avo-3 → Avo-4 rename you applied (container_width, resource_default_view) and the old line it replaced.
Follow-ups the change implies: a server restart to reload the initializer; a scalable session store if you enabled persistence; disabling cache_resources_on_index_view if they gate fields by role.
When a setting has a per-resource equivalent (default_view_type, pagination, density), note it so they know they can override it on individual resources.
Redirect anything out of scope to the right skill: install/mount/license → avo-setup, appearance/theming → avo-branding-appearance, menus/search/breadcrumbs/shortcuts → avo-navigation-search, caching depth → avo-performance, authorization → avo-authorization.
