Rails表单日期选择器

Question

在结帐时，我提示用户确认他的地址和required_date接收部件。下面显示了需要确认的@auction属性的表单。所有的地址行都已经填满了。但是日期字段被清除，我希望日期字段用已经选择的日期(@auction.required_date)填充，这样如果required_date没有改变，用户就不必重新选择日期。

这是表单

.form-container
  %p#alert= alert
  = form_for(@auction, html: { class: "inline-form" }, remote: true ) do |f|
    - if @auction.errors.any?
      #error_explanation
        %h2
          = pluralize(@auction.errors.count, "error")
          prohibited this auction from being saved:
        %ul
          - @auction.errors.full_messages.each do |message|
            %li= message
    .field.form-group
      = f.text_field :destination_address, class: "form-control", placeholder: "Destination Street Address"
    .field.form-group
      = f.text_field :destination_city, class: "form-control", placeholder: "Destination City"
    .field.form-group
      = f.text_field :destination_state, class: "form-control", placeholder: "Destination State/Region"
    .field.form-group
      = f.text_field :destination_zip, class: "form-control", placeholder: "Destination Zip Code"
    .field.form-group
      = f.text_field :destination_country, class: "form-control", placeholder: "Destination Country"
    .field
      = f.date_field :required_date, class: "form-control datepicker", placeholder: "Required Delivery Date"
    %br/
    .actions.submit_button
      = f.submit 'Submit', class: "btn custom-btn"
    %br/

:javascript
  $('.datepicker').pickadate({
    selectMonths: true
  });

Answer 1

我相信你可以这样做:

= f.date_field :required_date, class: "form-control datepicker", placeholder: "Required Delivery Date", value: @auction.required_date

，它应该填充日期字段。

Answer 2

我想你必须使用strftime以正确的格式添加值，例如:

value: @auction.required_date.strftime('%m/%d/%Y')
