Django - 分别打印每个 model/form

Question

我使用 {{form}} 打印出整个表格。我想知道有什么办法可以分别打印每个元素吗？我尝试了 {{survey.location}} 或 {{survey.get_location_display}} 但它不起作用。下面可能是 models.py、forms.py、views.py 和 home.html。

models.py

from django.db import models

class Survey(models.Model):
    location = models.CharField(max_length=120, blank=False, null=True)
    education = models.CharField(max_length=120, blank=False, null=True)

forms.py

from django import forms
from .models import Survey
    class Meta:
        model = Survey
        fields = ["location", "education"]

views.py

from django.shortcuts import render
from .forms import SurveyForm

def homepage(request):
    if request.method == 'POST':
        form = SurveyForm(request.POST or None)
        if form.is_valid():
            instance = form.save(commit=False)
            instance.save()
    else:
        form = SurveyForm()
    return render(request, "home.html", {"form": form})

home.html

<form method='POST' action= "" >{% csrf_token %}
    {{form.as_p}}
    <input type="submit" value="Submit"/>    
</form>

Answer 1

您可以使用{{form.field_name}}单独打印表格的每个字段。

来自 rendering fields manually:

上的 Django 文档

Each field is available as an attribute of the form using {{ form.name_of_field }}, and in a Django template, will be rendered appropriately.

{{form.location}} # renders 'location' field of a form

{{form.education}} # renders 'education' field of a form

模板中的

{{form.location}} 将呈现如下内容：

<input type="text" name="location" maxlength="120" ../>

Answer 2

是的，这是 docs 的一种方式：

<form action="/contact/" method="post">
    {{ form.non_field_errors }}
    <div class="fieldWrapper">
        {{ form.subject.errors }}
        <label for="id_subject">Email subject:</label>
        {{ form.subject }}
    </div>
    <div class="fieldWrapper">
        {{ form.message.errors }}
        <label for="id_message">Your message:</label>
        {{ form.message }}
    </div>
    <div class="fieldWrapper">
        {{ form.sender.errors }}
        <label for="id_sender">Your email address:</label>
        {{ form.sender }}
    </div>
    <div class="fieldWrapper">
        {{ form.cc_myself.errors }}
        <label for="id_cc_myself">CC yourself?</label>
        {{ form.cc_myself }}
    </div>
    <p><input type="submit" value="Send message" /></p>
</form>
