The correct form action for customised crud templates is not simply
<form action="data" enctype="multipart/form-data" method="post">
as I stated in my previous post
The correct action for a create form for example can be found by
taking away '_create' from form.formname. For example
<form action="data/create/{{=form.formname.split('_')[0]}}"
enctype="multipart/form-data" method="post">
You can look at examples or the source code to get the appropriate
action names and so form name manipulations for form actions.
