<%= f.input :shoe_size, :as => :number, :in => 3..15, :step => 1 %>
@example Use :in with a Range as a shortcut for :min/:max
<%= f.input :shoe_size, :as => :number, :min => 3, :max => 15, :step => 1, :input_html => { :class => “special” } %>
@example Min/max/step also work as options
<%= f.input :shoe_size, :as => :number, :input_html => { :min => 3, :max => 15, :step => 1, :class => “special” } %>
@example Pass attributes down to the ‘<input>` tag with :input_html

@example Full form context and output
* change the validations to use `:less_than_or_equal_to` or `:greater_than_or_equal_to`
* change the database column type to an `:integer` (if appropriate)
* manually specify the `:min` or `:max` for the input
The solution is to either:
* the validation uses `:less_than` or `:greater_than`
* the model’s database column type is a ‘:float` or `:decimal`
* you haven’t specified a ‘:min` or `:max` for the input
will be raised when the following conditions are all true:
the model’s validations (when provided). An ‘IndeterminableMinimumAttributeError` exception
Sensible default values for the `min`, `max` and `step` attributes are found by reflecting on
but can be applied to any text-like input with `:as => :number`.
and `:decimal`, as well as `:integer` columns that aren’t used for ‘belongs_to` associations,
`<li>` wrapper. This is the default input choice for all database columns of the type `:float`
Outputs a simple `<label>` with a HTML5 `<input type=“number”>` wrapped in the standard
