Я видел много руководств по этому вопросу (я новичок в Django), и единственная проблема, которую я смог найти, это поднять форму. Validation("...") не отображалась в моем шаблоне HTML и не отображалась не останавливать отправку формы.
Я пробовал много вариантов, включая искусственный интеллект, но все равно сталкивался с теми же проблемами. Если я допустил глупую ошибку, укажите на нее, чтобы я знал, что в следующий раз этот код — всего лишь мой проект, чтобы я мог научиться программировать Django.
HTML:
{% csrf_token %}
{% if form.non_field_errors %}
{{ form.non_field_errors }}
{% endif %}
{% if form.errors %}
{{ form.errors }}
{% endif %}
{{ form.username.label }}
{{ form.username }}
{% for error in form.username.errors %}
{{ error }}
{% endfor %}
{{ form.email.label }}
{{ form.email }}
{% for error in form.email.errors %}
{{ error }}
{% endfor %}
{{ form.password.label }}
{{ form.password }}
{% for error in form.password.errors %}
{{ error }}
{% endfor %}
{{ form.repassword.label }}
{{ form.repassword }}
{% for error in form.repassword.errors %}
{{ error }}
{% endfor %}
