Django - 动态添加字段

Question

目标: 通过按下按钮动态地向表单添加字段.提交后,将这些值存储在列表中的所有字段中.

(我已经查看了Stack Overflow上的其他问题,并试图找到一个基本的教程/解释如何执行此操作:动态地向表单添加字段)

我不确定我需要查找/研究什么.我知道它将涉及JavaScript,但它的Django方面,我不确定它将如何工作.

我为初学者创建了一个基本表单:

Models.py

from django.db import models

class SimpleForm(models.Model):
    basic_field = models.CharField(max_length=200)

Forms.py

from django import forms
from models import SimpleForm

class SimpleForm(forms.ModelForm):

class Meta:
    model = SimpleForm
    fields = ['basic_field']

Views.py

from django.shortcuts import render
from forms import SimpleForm

def index(request):
    if request.method == "POST":
        # For loop to iterate over dynamically created fields
        # Store values in list
    else:
        form = SimpleForm()
    return render(request, "index.html", {'form':form})

的index.html

{% block content %}
    <h1>Simple Form</h1>
    <form method="POST" class="post-form">{% csrf_token %}
        {{ form.as_p }}
        <button type="button" class="btn-default">Add Another Field</button>
        <button type="submit" class="btn-default">Submit</button>
    </form>
{% endblock %}

Answer 1

尝试使用django-formsets.你可以从这个简洁的教程开始.

基本上,您需要做的是在views.py中从表单中创建一个formset.

    from django.forms.formsets import formset_factory
    CompoundFormset = formset_factory(SimpleForm,max_num=10,extra=1)
