datetime_field

Returns a text_field of type “datetime-local”.

datetime_field("user", "born_on") # => <input id="user_born_on" name="user[born_on]" type="datetime-local" /> 

The default value is generated by trying to call strftime with “%Y-%m-%dT%T” on the object’s value, which makes it behave as expected for instances of DateTime and ActiveSupport::TimeWithZone.

@user.born_on = Date.new(1984, 1, 12) datetime_field("user", "born_on") # => <input id="user_born_on" name="user[born_on]" type="datetime-local" value="1984-01-12T00:00:00" /> 

You can create values for the “min” and “max” attributes by passing instances of Date or Time to the options hash.

datetime_field("user", "born_on", min: Date.today) # => <input id="user_born_on" name="user[born_on]" type="datetime-local" min="2014-05-20T00:00:00.000" /> 

Alternatively, you can pass a String formatted as an ISO8601 datetime as the values for “min” and “max.”

datetime_field("user", "born_on", min: "2014-05-20T00:00:00") # => <input id="user_born_on" name="user[born_on]" type="datetime-local" min="2014-05-20T00:00:00.000" /> 

By default, provided datetimes will be formatted including seconds. You can render just the date, hour, and minute by passing include_seconds: false.

@user.born_on = Time.current datetime_field("user", "born_on", include_seconds: false) # => <input id="user_born_on" name="user[born_on]" type="datetime-local" value="2014-05-20T14:35" />
