Overview

A FormPanel with paging toolbar. Allows browsing and editing records one-by-one.

Configuration

Besides Netzke::Basepack::FormPanel config options, accepts:

  • scope - specifies how the data should be filtered. When it's a symbol, it's used as a scope name. When it's a string, it's a SQL statement (passed directly to ActiveRecord::Relation#where). When it's a hash, it's a conditions hash (passed directly to ActiveRecord::Relation#where). When it's an array, it's expanded into an SQL statement with arguments (passed directly to ActiveRecord::Relation#where), e.g.:

    :scope => ["id > ?", 100])

    When it's a Proc, it's passed the model class, and is expected to return an ActiveRecord::Relation, e.g.:

    :scope => { |rel| rel.where(:id.gt => 100).order(:created_at) }
