+ The form field {{ view.first_field_with_errors }} has errors,

+ you did not include the field in the page.
+ There are 2 ways to fix this:
+
+ -
+ Include the field with the
formfield tag, e.g.
+ {% templatetag openblock %}
+ formfield player.{{ view.first_field_with_errors }}
+ {% templatetag closeblock %}
+
+ -
+ If you are not using
formfield but are instead
+ writing the raw HTML for the form input,
+ remember to include
+ {% templatetag openvariable %}
+ form.{{ view.first_field_with_errors }}.errors
+ {% templatetag closevariable %}
+ somewhere in your page's HTML.
+
+
+
+ {% if view.other_fields_with_errors %}
+
The following other field(s) have the same issue:
+
+ {% for field_with_error in view.other_fields_with_errors %}
+ -
+
{{ field_with_error }}
+
+ {% endfor %}
+
+
+ While debugging, you can display all errors in the form with
+ {% templatetag openvariable %}
+ form.errors
+ {% templatetag closevariable %}.
+

+

error
+ form.errors or form.foo.errors:
