View Source LiveAdmin
An admin UI for Phoenix applications built on Phoenix LiveView and Ecto.
Significant features:
- First class support for multi tenant applications via Ecto's
prefix
option - Overridable views and API
- Easily add custom actions at the schema and record level
- Ability to edit (nested) embedded schemas
- i18n via Gettext
installation
Installation
First, ensure your Phoenix app has been configured to use LiveView.
Add to your app's deps
:
{:live_admin, "~> 0.11.5"}
Configure a module to act as a LiveAdmin resource:
defmodule MyApp.MyResource do
use LiveAdmin.Resource, schema: MyApp.Schema
end
Note: if you use an Ecto schema you can omit the `schema' option.
In your Phoenix router, inside a scope configured to run LiveView (:browser
if you followed the default installation), add the resource to a LiveAdmin instance:
elixir import LiveAdmin.Router scope "/" do pipe_through: :browser live_admin "/my_admin" do admin_resource "/my_schemas", MyApp.MyResource end end
Finally, tell LiveAdmin what Ecto repo to use to run queries in your runtime.ex
:
config :live_admin, ecto_repo: MyApp.Repo
That's it, now an admin UI for MyApp.Schema
will be available at /my_admin/my_schemas
.
## Configuration
One of the main goals of LiveAdmin is to require as little config as possible.
It should work out of the box, with only the above, for the vast majority of common
app admin needs.
However, if you want to customize the behavior of one or more resources, including how records
are rendered or changes are validated, or to add custom behaviors, there are a variety of configuration options
available. This includes component overrides if you would like to completely control
every aspect of a particular resource view, like the edit form. For a complete list of options, see the LiveAdmin.Resource
docs.
For additional convenience and control, configuration in LiveAdmin can be set at 3 different levels.
From most specific to most general, they are resource, admin instance, and global.
For concrete examples of the various config options and to see them in action, consult the development app.
### Resource
The second argument passed to use LiveAdmin.Resource
will configure only that specific resource,
in any LiveView it is used. If the module is not an Ecto schema, the :schema
option must be passed.
If you would like the same schema to behave differently in different LiveAdmin instances, or different
routes in the same instance, you must create multiple resource modules to contain that configuration.
### Admin instance
The second argument passed to live_admin
will configure defaults for all resources in the group
that do not specify the same configuration. Currently only component overrides and the repo can be
configured at this level.
### Global
All resource configuration options can also be set in the LiveAdmin app runtime config. This will set a global
default to apply to all resources unless overridden in their individual config, or the LiveAdmin instance.
Additionally, the following options can only be set at the global level:
css_overrides
- a binary or MFA identifying a function that returns CSS to be appended to app css
session_store
- a module implementing the LiveAdmin.Session.Store
behavior, used to persist session data
gettext_backend
- a module implementing the Gettext API. It is expected to implement locales/0
returning a list of binary locale names
## i18n
LiveAdmin wraps all static strings in the UI with Gettext calls, but currently it does not provide any locales by default, so you will need
to make sure they have been set up correctly for a custom backend. Unfortunately it is not currently possible to use
Gettext's utilities to automatically extract the pot files so you will need to do this manually.
To avoid conflicts with your own app's translations, it is recommended to create separate Gettext backends for LiveAdmin.
## Development environment
This repo has been configured to run the application in Docker using Compose.
The Phoenix app is running the app
service, so all mix command should be run there. Examples:
docker compose run web mix test
