[Grok-dev] overridding default form templates

[Joshua Immanuel]

Hello,

I was trying to override the default form template for grok.AddForm
using grok.PageTemplateFile

                class AddUser(grok.AddForm):
                    grok.context(UserFolder)
                    grok.name('add_user')
                    form_fields = grok.AutoFields(User)
                    label = "Add new user"
                    template = grok.PageTemplateFile(
                        os.path.join('form_templates','dash_form.pt'))
                
                    @grok.action('Add user')
                    def add(self, **data):
                        ...
                        return self.redirect(self.url(self.context))
                
In the overridden template file I was using a macro to fill a slot with
form contents.

        <div xmlns:tal="http://xml.zope.org/namespaces/tal"
             xmlns:metal="http://xml.zope.org/namespaces/metal"
             metal:use-macro=
        
        "path:context/@@dashboard/template/macros/dashboard_layout">
          <tal:block metal:fill-slot="dashboard_content">
            <form action="." tal:attributes="action request/URL" 
                  method="post" class="edit-form"
                  enctype="multipart/form-data">
              ...
          </tal:block>
        </div>

But, while rendering this page I get the following traceback

Am I missing something? Please guide me.
