我目前正在努力使用Django表单。基于票证模型,我生成了这个表单集,用户可以在其中选择所需票证的数量。将它们重定向到结帐页面后。
我的问题是,当我使用{{form.ticket}}时,我会得到一个选择字段,但这不是我想要的。我只想打印出票,如下面的截图所示。
任何人都可以帮助我吗?
应该如何:
目前情况如何:
views.py
from django.forms import formset_factory
from django.shortcuts import redirect, render
from .forms import EntryModelForm
from .models import Ticket
from orders.models import Order, Entry
# Create your views here.
def choose_ticket_and_quantity(request):
tickets = []
for ticket in Ticket.objects.all():
tickets.append({'ticket': ticket})
EntryFormSet = formset_factory(EntryModelForm, extra=0)
formset = EntryFormSet(initial=tickets)
if request.POST:
o = Order.objects.create()
request.session['order_id'] = o.order_id
formset = EntryFormSet(request.POST, initial=tickets)
if formset.is_valid():
for form in formset:
if form.cleaned_data['quantity'] > 0:
entry = form.save(commit=False)
entry.order = o
entry.save()
return redirect('http://127.0.0.1:8000/checkout')
return render(request, "tickets/choose_ticket_and_quantity.html", {'formset': formset})
forms.py
from django import forms
from orders.models import Entry
class EntryModelForm(forms.ModelForm):
class Meta:
model=Entry
fields = ['ticket', 'quantity']
choose_ticket_and_quantity.html
<form method="post" action="">
{% csrf_token %}
{{ formset.management_form }}
{% for form in formset %}
<ul>
<li>{{ form.ticket }}</li>
<li>{{ form.quantity }}</li>
</ul>
{% endfor %}
<p><input type="submit" value="Checkout"></p>
</form>
我在这里也尝试了这一点,但遗憾的是,由于我的表格无法再被验证并且所有票证类型已经打印在一起,因此无法正常工作:
{% for choice in form.ticket.field.choices %}
{{choice.1}}
{% endfor %}

您希望显示该字段的值:
<li>{{ form.ticket.value }}</li>

试试这个
在app / templatetags中添加模板标签get_ticket.py
(也添加__init__.py
)
from django import template
register = template.Library()
# import Ticket model
@register.simple_tag
def get_ticket(pk):
ticket = Ticket.objects.get(pk=int(pk))
return ticket.name # is it name?
在您的模板中
{% load get_ticket %}
<form method="post" action="">
{% csrf_token %}
{{ formset.management_form }}
<ul>
{% for form in formset %}
<li>
<strong>{% get_ticket form.ticket.value %}</strong><br>
<input type="hidden" name='{{form.ticket.name}}' value='{{form.ticket.value}}'>
{{ form.quantity }}
</li>
{% endfor %}
</ul>
<p><input type="submit" value="Checkout"></p>
</form>
