#alchemy_datepicker(object, method, html_options = {}) ⇒ Object

Renders a textfield ready to display a datepicker

Uses a HTML5 <input type=“date”> field. A Javascript observer converts this into a fancy Datepicker. If you pass ‘datetime’ as :type the datepicker will also have a Time select.

The date value gets localized via I18n.l. The format on Time and Date is datepicker or datetimepicker, if you pass another type.

Date Example

<%= alchemy_datepicker(@person, :birthday) %>

Datetime Example

<%= alchemy_datepicker(@page, :public_on, type: 'datetime') %>

Parameters:

  • object (ActiveModel::Base) —

    An instance of a model

  • method (String or Symbol) —

    The attribute method to be called for the date value

  • html_options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (html_options):

  • :type (String) — default: date —

    The type of text field

  • :class (String) — default: type —

    CSS classes of the input field

  • :value (String) — default: value of method on object —

    The value the input displays. If you pass a String its parsed with Time.parse

def alchemy_datepicker(object, method, html_options = {})
  type = html_options.delete(:type) || 'date'
  date = html_options.delete(:value) || object.send(method.to_sym).presence
  date = Time.zone.parse(date) if date.is_a?(String)
  value = date ? l(date, format: "#{type}picker".to_sym) : nil

  text_field object.class.name.demodulize.underscore.to_sym,
    method.to_sym, {type: type, class: type, value: value}.merge(html_options)
end

#button_with_confirm(value = "", url = "", options = {}, html_options = {}) ⇒ Object

Note:

The method option in the html_options hash gets passed to the form_tag helper!

Returns a form and a button that opens a modal confirm dialog.

After confirmation it proceeds to send the form’s action.

Example:

<%= button_with_confirm('pay', '/admin/orders/1/pay', message: 'Do you really want to mark this order as payed?') %>

Parameters:

  • value (String) (defaults to: "") —

    The content inside the <a> tag

  • url (String) (defaults to: "") —

    The url that gets opened after confirmation

  • options (Hash) (defaults to: {}) —

    Options for the Alchemy confirm dialog (see also app/assets/javascripts/alchemy/alchemy.confirm_dialog.js.coffee)
