calculate(operation, column_name, options = {}) Instance Public methods This calculates aggregate values in the given column. Methods for count, sum, average, minimum, and maximum have been added as shortcuts. There are two basic forms of output: * Single aggregate value: The single value is type cast to Fixnum for COUNT, Float for AVG, and the given column's type for everything else. * Grouped values: This returns an ordered hash of the values and groups them. It takes either

text_field(object_name, method, options = {}) Instance Public methods Returns an input tag of the âtextâ type tailored for accessing a specified attribute (identified by method) on an object assigned to the template (identified by object). Additional options on the input tag can be passed as a hash with options. These options will be tagged onto the HTML as an HTML element attribute as in the example shown. Examples text_field(:post, :title, size: 20) # => <input type="text"

str.to_r â rational Instance Public methods Returns a rational which denotes the string form. The parser ignores leading whitespaces and trailing garbage. Any digit sequences can be separated by an underscore. Returns zero for null or garbage string. NOTE: '0.3'.to_r isn't the same as 0.3.to_r. The former is equivalent to '3/10'.to_r, but the latter isn't so. ' 2 '.to_r #=> (2/1) '300/2'.to_r #=> (150/1) '-9.2'.to_r #=> (-46/5) '-9.2e2'.to_r
