Instance Method Details

#report_table(number = :all, options = {}) ⇒ Object

Creates a Ruport::Data::Table from an ActiveRecord find. Takes parameters just like a regular find.

Additional options include:

:only

An attribute name or array of attribute names to include in the results, other attributes will be excuded.

:except

An attribute name or array of attribute names to exclude from the results.

:methods

A method name or array of method names whose result(s) will be included in the table.

:include

An associated model or array of associated models to include in the results.

:filters

A proc or array of procs that set up conditions to filter the data being added to the table.

:transforms

A proc or array of procs that perform transformations on the data being added to the table.

:record_class

Specify the class of the table’s records.

:eager_loading

Set to false if you don’t want to eager load included associations.

The :only, :except, :methods, and :include options may also be passed to the :include option in order to specify the output for any associated models. In this case, the :include option must be a hash, where the keys are the names of the associations and the values are hashes of options.

Any options passed to report_table will disable the options set by the acts_as_reportable class method.

Example:

class Book < ActiveRecord::Base
  belongs_to :author
  acts_as_reportable
end

Book.report_table(:all, :only => ['title'],
  :include => { :author => { :only => 'name' } }).as(:html)

Returns:

an html version of the table with two columns, title from the book, and name from the associated author.

Example:

Book.report_table(:all, :include => :author).as(:html)

Returns:

an html version of the table with all columns from books and authors.

Note: column names for attributes of included models will be qualified with the name of the association.
