如何保存django模型形式，crispy，我无法将数据保存到数据库

Question

欢迎各位朋友

我需要你的帮助。

我无法将数据从表单保存到我的数据库。

这当然可能很简单，但我不知道该怎么做。

urls.py

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^$', views.product_list, name='product_list'),
    url(r'^busy/', views.product_busy, name='product_busy'),
]

models.py

from django.db import models
from django.core.urlresolvers import reverse

class Busy(models.Model):
    name = models.CharField(max_length=200, db_index=True)
    slug = models.SlugField(max_length=200, db_index=True)


    class Meta:
        ordering = ('name',)
        index_together = (('id', 'slug'),)
        verbose_name = 'busy'
        verbose_name_plural = 'busy'

    def __str__(self):
        return self.nazwa

    def get_absolute_url(self):
        return reverse('konfigurator:product_busy',
                       args=[self.id, self.slug])

forms.py

from django import forms
from django.utils.translation import ugettext_lazy as _, ugettext    
from crispy_forms import layout, bootstrap
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Layout, Fieldset, ButtonHolder, Submit, MultiField, Div, Field, Button
from .models import Busy

class Konfig(forms.ModelForm):
    class Meta:
        model = Busy
        fields = ['name','slug']

    def __init__(self, *args, **kwargs):
        super(Konfig, self).__init__(*args, **kwargs)

        self.helper = FormHelper()
        self.helper.form_action = "."
        self.helper.form_method = "POST"
        self.helper.form_class = 'order-form'

        self.helper.layout = layout.Layout(
            layout.Fieldset(
                _("XXX"),
                layout.Field("name"),
                layout.Field("slug"),
            ),

            bootstrap.FormActions(
                layout.Submit("submit", _("Send"),
                             css_class="right"),
            )
        )

views.py

from django.shortcuts import render, get_object_or_404
from .models import Busy
from django.shortcuts import render
from .forms import Konfig
from django.conf import settings
from django.http import HttpResponse
from django.template.loader import render_to_string

def product_list(request):
    return render(request,'konfig/product/list.html')

def product_busy(request):
    return render(request,'konfig/product/busy.html', {'form': Konfig()})

def konfig(request):
    form = Konfig()
    return render(request, "konfig/product/busy.html", {'form': form})

busy.html

{% extends "konfig/base.html" %}
{% load crispy_forms_tags %}
{% crispy konfig_form konfig_form.helper %}

{% block title %}
    XX
{% endblock %}

{% block content %}
    <div class="order-info2">
        {% crispy form %}
    </div>

{% endblock %}

如何解决问题？

非常感谢你的帮助。

更新views.py

def konfig(request):
    if request.method == 'POST':
        form = Konfig(request.POST)
        if form.is_valid():
            name = form.save()
            name.save()
            name = Busy.objects.create(name=name)
            return render(request,
                          'konfig/product/busy.html',
                          {'name': name})
    else:
        form = Konfig()
    return render(request,
                  'konfig/product/busy.html',
                  {'form': form})

我试过了，还是不行。也许有上下文处理器。

您正在初始化您的表单，没关系，但是您没有接受来自 POST 请求的任何内容。

如果你阅读更多有关 django 中的 http 请求的内容会更好。

无论如何，我会做这样的事情...

def konfig(request):
    if request.method == "POST":
        form = Konfig(request.POST)
        if form.is_valid():
            form.save()
    else:
        form = Konfig()
    return render ( request, 'your_template', {'form':form})
