If it's a layout object, we call its render method, otherwise we instantiate a BoundField and render it using default template 'CRISPY_TEMPLATE_PACK/field.html' The field is added to a list that the form holds called `rendered_fields` to avoid double rendering fields. :param form: The form/formset to which that field belongs to. :param form_style: A way to pass style name to the CSS framework used. :template: Template used for rendering the field. :layout_object: If passed, it points to the Layout object that is being rendered. We use it to store its bound fields in a list called `layout_object.bound_fields` :attrs: Attributes for the field's widget :template_pack: Name of the template pack to be used for rendering `field` :extra_context: Dictionary to be added to context, added variables by the layout object NZCRISPY_FAIL_SILENTLYTrenderrwidgetstypehiddenz"Could not resolve form field '%s'.)exc_inforendered_fieldsz(A field should only be rendered once: %s bound_fields)field labelclassZ flat_attrs)!keysr r rhasattrrrwidget isinstancedictlen enumeratezipZ hidden_widgetrattrsupdateKeyError ExceptionloggingwarningsysrraddZcrispy_field_templaterrrlistappendrflatten)rformZ form_stylecontexttemplaterZ layout_objectr$rZ extra_contextkwargsZ added_keysZ FAIL_SILENTLYZ bound_fieldZfield_instancerZ list_attrsindexrattrhtmlr r r render_fieldsp               r6cCstdd|DS)z Convert a dictionary of attributes to a single string.
