datepicker_field_value error

[illnino]

Hi

It has errors when creating static pages and posts in spree 1.3.1. All returned below error message.

undefined method `datepicker_field_value' for #<#<Class:0x007fa109498f48>:0x007fa109230148>

However, it did list the static pages and posts in admin cms relating panel.

When I visit /pages , it returned

undefined method `each' for nil:NilClass

1: <% pages.each do |page| %>
2:     <div class="page-preview">
3:       <h2> <%= page.name %></h2>
4:       <div class="page-date"> <%= t(:write_in) %>: <%= post_date page %> </div>

It seems pages is null.

and when visit /blog, another error found

undefined local variable or method `get_taxonomies' for #<#<Class:0x007fa10561a938>:0x007fa107dca000>
Extracted source (around line #2):

1: <nav id="taxonomies" class="sidebar-item" data-hook>
2:   <% get_taxonomies.each do |taxonomy| %>
3:     <h6 class='taxonomy-root'><%= t(:shop_by_taxonomy, :taxonomy => taxonomy.name) %></h6>
4:     <%= taxons_tree(taxonomy.root, @taxon, Spree::Config[:max_level_in_taxons_menu] || 1) %>
5:   <% end %>

May you please kindly check?
