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

Renders a textfield ready to display a datepicker

A Javascript observer converts this into a fancy Datepicker. If you pass ‘datetime’ as :type the datepicker will also have a Time select. If you pass ‘time’ as :type the datepicker will only have a Time select.

This helper always renders “text” as input type because: HTML5 supports input types like ‘date’ but Browsers are using the users OS settings to validate the input format. Since Alchemy is localized in the backend the date formats should be aligned with the users locale setting in the backend but not the OS settings.

Date Example

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

Datetime Example

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

Time Example

<%= alchemy_datepicker(@meeting, :starts_at, type: 'time') %>

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):

  • :data-datepicker-type (String) — default: type —

    The value of the data attribute for the type

  • :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&.iso8601

  input_field = text_field object.class.name.demodulize.underscore.to_sym,
    method.to_sym, {type: "text", class: type, value: value}.merge(html_options)

  content_tag("alchemy-datepicker", input_field, "input-type" => type)
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)

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

    HTML options that get passed to the button_tag helper.
