6.3 渲染表单

渲染表单 render form

There're 3 method to render form
1) define ModelForm
2) define model, use modelform_factory to get form
3) reuse add_view to get form which already has set all the fieldsets

built-in 渲染

form.as_ul
form.as_p
form.as_table

在django_comments/templates/comments/form.html里面，这个是评论的表单渲染

{% load comments i18n %}
<form action="{% comment_form_target %}" method="post">{% csrf_token %}
  {% if next %}
    <div><input type="hidden" name="next" value="{{ next }}"/></div>{% endif %}
  {% for field in form %}
    {% if field.is_hidden %}
      <div>{{ field }}</div>
    {% else %}
      {% if field.errors %}{{ field.errors }}{% endif %}
      <p
        {% if field.errors %} class="error"{% endif %}
        {% ifequal field.name "honeypot" %} style="display:none;"{% endifequal %}>
        {{ field.label_tag }} {{ field }}
      </p>
    {% endif %}
  {% endfor %}
  <p class="submit">
    <input type="submit" name="post" class="submit-post" value="{% trans "Post" %}"/>
    <input type="submit" name="preview" class="submit-preview" value="{% trans "Preview" %}"/>
  </p>
</form>

admin的表单渲染如下 django\contrib\admin\templates\admin\change_form.html里面会有如下fieldset.html调用

{% block field_sets %}
{% for fieldset in adminform %}
  {% include "admin/includes/fieldset.html" %}
{% endfor %}
{% endblock %}

admin/includes/fieldset.html

<fieldset class="module aligned {{ fieldset.classes }}">
    {% if fieldset.name %}<h2>{{ fieldset.name }}</h2>{% endif %}
    {% if fieldset.description %}
        <div class="description">{{ fieldset.description|safe }}</div>
    {% endif %}
    {% for line in fieldset %}
        <div class="form-row{% if line.fields|length_is:'1' and line.errors %} errors{% endif %}{% if not line.has_visible_field %} hidden{% endif %}{% for field in line %}{% if field.field.name %} field-{{ field.field.name }}{% endif %}{% endfor %}">
            {% if line.fields|length_is:'1' %}{{ line.errors }}{% endif %}
            {% for field in line %}
                <div{% if not line.fields|length_is:'1' %} class="field-box{% if field.field.name %} field-{{ field.field.name }}{% endif %}{% if not field.is_readonly and field.errors %} errors{% endif %}{% if field.field.is_hidden %} hidden{% endif %}"{% elif field.is_checkbox %} class="checkbox-row"{% endif %}>
                    {% if not line.fields|length_is:'1' and not field.is_readonly %}{{ field.errors }}{% endif %}
                    {% if field.is_checkbox %}
                        {{ field.field }}{{ field.label_tag }}
                    {% else %}
                        {{ field.label_tag }}
                        {% if field.is_readonly %}
                            <p>{{ field.contents }}</p>
                        {% else %}
                            {{ field.field }}
                        {% endif %}
                    {% endif %}
                    {% if field.field.help_text %}
                        <p class="help">{{ field.field.help_text|safe }}</p>
                    {% endif %}
