This widget allows you to conveniently display, edit, validate json data on user form. It has multiple display options (tree, text, code). If a field is read-only, the widget opens only for viewing. The widget is based on JSONEditor by Jos de Jong. Usage: # model class Model(models.Model): json_field = fields.Json(string="Your JSON field") # view <form>; .... <field name="json_field" widget="json_widget" /> .... </form>
