Django未显示所有身份验证表单错误

我正在使用django allauth，每当我在登录表单中输入错误的密码时，页面就会重新加载，并且不会显示任何错误。这是我的html代码：

    <form class="login" method="POST" action="{% url 'account_login' %}">
                        {% if form.errors %}
    {% for field in form %}
    {% for error in field.errors %}
    <div class="alert alert-error">
   <span><b> {{error}} </b><span>
    </div>
    {% endfor %}
    {% endfor %}
    {% endif %}
  {% csrf_token %}

   <div class="mdl-textfield mdl-js-textfield mdl-textfield--floating-label">
  {{ form.login }}
  <label class="mdl-textfield__label" for="id_login">Username/Email:</label>
  </div>
   <div class="mdl-textfield mdl-js-textfield mdl-textfield--floating-label">
  {{ form.password }}
  <label class="mdl-textfield__label" for="id_password">Password</label>
  </div>

  <label class="mdl-checkbox mdl-js-checkbox mdl-js-ripple-effect" for="id_remember">
   {{form.remember}}<span class='mdl-checkbox__label 'align='left'>Remember me</span>
  </label></br>
  {% if redirect_field_value %}
  <input type="hidden" name="{{ redirect_field_name }}" value="{{ redirect_field_value }}" />
  {% endif %}
  <a class="button secondaryAction" href="{% url 'account_reset_password' %}">{% trans "Forgot Password?" %}</a><br/></br>
  <button class="mdl-button mdl-js-button  mdl-js-ripple-effect mdl-button--raised mdl-button--colored" type="submit">{% trans "Sign In" %}</button>
  <br/>
  <br/>
</form>

        return ret

login = LoginView.as_view()

除了附加到特定字段的错误之外，请确保检查

{{form.non_field_errors}}

如果任何一个仍然有问题，那么您可以使用这个

{% if form.errors %}
{% for field in form %}
    {% for error in field.errors %}
        <div class="alert alert-error">
            <strong>{{ error|escape }}</strong>
        </div>
    {% endfor %}
{% endfor %}
{% for error in form.non_field_errors %}
    <div class="alert alert-error">
        <strong>{{ error|escape }}</strong>
    </div>
{% endfor %}
{% endif %}

{%if form.errors%}
{%形式的字段为%}
{%字段中有错误。错误%}
{{error | escape}}
{%endfor%}
{%endfor%}
{%表示表单中的错误。非\u字段\u错误%}
{{error | escape}}
{%endfor%}
{%endif%}

你能发布呈现

signup.html

的视图吗？@souldeux该视图不是我写的，它来自django allauthpackage@souldeux我在问题中已经上传了，我不确定，我对django allauth没有多少经验。我认为唯一有帮助的是检查模板中的

{{form.non_field_errors}}

。@souldex，它是正确的。您可以将其作为答案发布，这样我就可以勾选它。

{% if form.errors %}
{% for field in form %}
    {% for error in field.errors %}
        <div class="alert alert-error">
            <strong>{{ error|escape }}</strong>
        </div>
    {% endfor %}
{% endfor %}
{% for error in form.non_field_errors %}
    <div class="alert alert-error">
        <strong>{{ error|escape }}</strong>
    </div>
{% endfor %}
{% endif %}
