django 小部件调整表单控件而不是操作

Question

在制作django board的时候遇到了问题

django 版本是 3.

我想要这样的形式。但是我的代码无法提醒我 "This field is required"

但是小部件调整表单控制不起作用。

哪一部分有问题？

我的代码是这样的

{% extends 'base.html' %}

{% load widget_tweaks %}

{% block title %}Start a New Topic{% endblock %}

{% block breadcrumb %}
  <li class="breadcrumb-item"><a href="{% url 'home' %}">Boards</a></li>
  <li class="breadcrumb-item"><a href="{% url 'board_topics' board.pk %}">{{ board.name }}</a></li>
  <li class="breadcrumb-item active">New topic</li>
{% endblock %}

{% block content %}
  <form method="post" novalidate>
    {% csrf_token %}

    {% for field in form %}
      <div class="form-group">
        {{ field.label_tag }}

                {% if form.is_bound %}
        {% if field.errors %}

          {% render_field field class="form-control is-invalid" %}
          {% for error in field.errors %}
            <div class="invalid-feedback">
              {{ error }}
            </div>
          {% endfor %}

        {% else %}
          {% render_field field class="form-control is-valid" %}
        {% endif %}
      {% else %}
        {% render_field field class="form-control" %}
      {% endif %}

      {% if field.help_text %}
        <small class="form-text text-muted">
          {{ field.help_text }}
        </small>
      {% endif %}
    </div>
  {% endfor %}

  <button type="submit" class="btn btn-success">Post</button>
</form>
{% endblock %}

Answer 1

尝试在您的表单中使用 bootstrap 或 django crispy 表单。

Answer 2

只需将您的代码更改为适当缩进即可

{% load widget_tweaks %}
{% block title %}Start a New Topic{% endblock %}
{% block breadcrumb %}
  <li class="breadcrumb-item"><a href="{% url 'home' %}">Boards</a></li>
  <li class="breadcrumb-item"><a href="{% url 'board_topics' board.pk %}">{{ board.name }}</a></li>
  <li class="breadcrumb-item active">New topic</li>
{% endblock %}

{% block content %}
<form method="post" novalidate>
    {% csrf_token %}

    {% for field in form %}
      <div class="form-group">
        {{ field.label_tag }}

        {% if form.is_bound %}
          {% if field.errors %}

            {% render_field field class="form-control is-invalid" %}
            {% for error in field.errors %}
              <div class="invalid-feedback">
                {{ error }}
              </div>
            {% endfor %}

          {% else %}
            {% render_field field class="form-control is-valid" %}
          {% endif %}
        {% else %}
          {% render_field field class="form-control" %}
        {% endif %}

        {% if field.help_text %}
          <small class="form-text text-muted">
            {{ field.help_text }}
          </small>
        {% endif %}
      </div>
    {% endfor %}

    <button type="submit" class="btn btn-success">Post</button>
  </form>
{% endblock %}```
