Administrate::Field::NestedHasMany

A plugin for nested has_many forms in Administrate, forked for rails 5 support.

Usage

Add to your Gemfile:

gem "administrate-field-nested_has_many",
      git: "https://github.com/NedelescuVlad/administrate-field-nested_has_many"

Run:

$ bundle install

Add to your application.js:

//=require cocoon

Add to your Foo model:

accepts_nested_attributes_for :bars

Add to your FooDashboard:

ATTRIBUTE_TYPES = [
  bars: Field::NestedHasMany.with_options(skip: :foo),
]

The skip option takes a single symbol or list of symbols. It will prevent the nested form from displaying the fields for those attributes.

If a Customer has_many :orders, and you want to render orders as a nested form on the customer edit page, then it is generally necessary to add skip: :customer to the options for the NestedHasMany field. Otherwise, Administrate will try to render a field for the order's :customer attribute, which breaks the nested form logic.
