[Odoo 11.0]How to inherit "Add to cart" modal in website_sale: error View ID refers to an uninstalled module

Ermin Trevisan

I'm simply trying to change the text of the button in the "Add to cart" model of the module website_sale.

This is my view:

    <template id="tw_frapolli_website_sale_improvements_options.modal" inherit_id="website_sale_options.modal" active="False" customize_show="True">

<!--> Replace button text "Proceed to Checkout" </!-->    

      <xpath expr="//div[hasclass('modal-footer']" position="replace">
        <div class="modal-footer">
          <a class="btn btn-default a-submit js_goto_shop"><i class="fa fa-chevron-left"/> <span class="hidden-xs">Continue Shopping</span><span class="visible-xs-inline">Continue</span></a>
          <a class="btn btn-primary pull-right a-submit"><i class="fa fa-shopping-cart fa-fw"/> <span class="hidden-xs">Get Quote</span><span class="visible-xs-inline">Get Quote</span></a>

However, I always receive the following error message:

 File "/usr/lib/python3/dist-packages/odoo/tools/", line 255, in _test_xml_id assert modcnt == 1, """The ID "%s" refers to an uninstalled module""" % (xml_id,) "The ID "tw_frapolli_website_sale_improvements_options.modal" refers to an uninstalled module" while parsing None:16, near <data inherit_id="website_sale_options.modal" active="False" customize_show="True">

Hello Ermin,

The code seems fine but can you please check once whether you have activated the "Optional Products" in website->settings under customer experience.

Thanks Jainesh, you are right, meanwhile I have learned more about the extension view fields "customize" and "active" and was able to solve the problem by overwriting the original view.
