Example

In order to create a grid:

class UsersGrid

  include Datagrid

  scope do
    User.includes(:group)
  end

  filter(:category, :enum, select: ["first", "second"])
  filter(:disabled, :xboolean)
  filter(:group_id, :integer, multiple: true)
  filter(:logins_count, :integer, range: true)
  filter(:group_name, :string, header: "Group") do |value|
    self.joins(:group).where(:groups => {:name => value})
  end

  column(:name)
  column(:group, order: -> { joins(:group).order(groups: :name) }) do |user|
    user.name
  end
  column(:active, header: "Activated") do |user|
    !user.disabled
  end

end

Basic grid api:

report = UsersGrid.new(
  :group_id => [1,2], 
  :logins_count => [1, nil],
  :category => "first",
  :order => :group,
  :descending => true
)

report.assets # => Array of User instances:
              # SELECT * FROM users WHERE users.group_id in (1,2) AND users.logins_count >= 1 AND users.category = 'first' ORDER BY groups.name DESC

report.header # => ["Name", "Group", "Activated"]
report.rows   # => [
              #      ["Steve", "Spammers", false],
              #      [ "John", "Spoilers", false],
              #      ["Berry", "Good people", true]
              #    ]
report.data   # => [ header, *rows]

report.to_csv # => Yes, it is

Grid DSL

In order to create a report, you need to define:

  • scope of objects to look through
  • filters that will be used to filter data
  • columns that should be displayed and sortable (if possible)

Scope

Default scope of objects to filter and display. In common case it is ActiveRecord::Base (or any other supported ORM) subclass with some generic scopes like:

scope do
  User.includes(:group)
end

More about scope

Filters

Each filter definition consists of:

  • name of the filter
  • type that will be used for value typecast
  • conditions block that applies to defined scope
  • additional options

Datagrid supports different type of filters including:

  • text
  • integer
  • float
  • date
  • datetime
  • boolean
  • xboolean - the select of "yes", "no" and any
  • enum - selection of the given values
  • string
  • dynamic - build dynamic SQL condition

More about filters

Columns

Each column is represented by name and code block to calculate the value.

column(:activated, :header => "Active", :order => "activated", :after => :name) do
  self.activated?
end

Some formatting options are also available. Each column is sortable.

Front end

Using Generator

Datagrid has a builtin generator:

rails g datagrid:scaffold skills

That gives you some code to play with out of the box:

create  app/grids/skills_grid.rb
create  app/controllers/skills_controller.rb
create  app/views/skills/index.html.erb
route  resources :skills
insert  app/assets/stylesheet/application.css

Customize Built-in partials

In order to get a control on datagrid built-in partials run:

rake datagrid:copy_partials
