首先，我会像这样重组你的模型。按照您当前的设置方式，选项/应用复选框关系会表现不佳。每个选项只能有一个与所有应用程序对象共享的布尔检查值。
楷模
from django.db import models
from django.utils.translation import ugettext as _
class Option(models.Model):
condition = models.CharField(
verbose_name = _(u'Condition Text'),
max_length = 255,
)
option = models.CharField(
verbose_name = _(u'Option Text'),
max_length = 255,
)
def __unicode__(self):
return self.condition
class App(models.Model):
title = models.CharField(
verbose_name = _(u'App Name'),
max_length = 255
)
slug = models.SlugField(
max_length = 50,
unique = True
)
activated = models.BooleanField(
verbose_name = _(u'Activated'),
default = False,
)
options = models.ManyToManyField(
Option,
through="AppOption"
)
def __unicode__(self):
return self.title
class AppOption(models.Model):
app = models.ForeignKey(
App,
verbose_name = _(u'App'),
)
option = models.ForeignKey(
Option,
verbose_name = _(u'Option'),
)
condition_activated = models.BooleanField(
verbose_name = _(u'Condition Activated'),
default = False,
)
option_activated = models.BooleanField(
verbose_name = _(u'Option Activated'),
default = False,
)
class Meta:
unique_together = (("app", "option"),)
def __unicode__(self):
return "%s %s (%s | %s | %s)" % (self.app, self.option, self.app.activated, self.option_activated, self.condition_activated)
其次，您应该使用模型表单集和模型表单，其中包含自定义逻辑......
形式
from django.forms.models import modelformset_factory
from django import forms
class AppOptionForm(forms.ModelForm):
class Meta:
model = AppOption
fields = ("app", "option", "condition_activated", "option_activated")
AppOptionFormSet = modelformset_factory(AppOption, form=AppOptionForm)
class AppForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(AppForm, self).__init__(*args, **kwargs)
if self.instance:
self.appoptions_prefix = "appoptions-%s"%self.instance.pk
self.appoptions_formset = AppOptionFormSet(prefix=self.appoptions_prefix,
queryset=AppOption.objects.filter(app=self.instance).order_by('option'))
class Meta:
model = App
fields = ("id", "activated",)
AppFormSet = modelformset_factory(App, form=AppForm)
好的，刚刚发生的是我们为它创建了一个模型表单AppOption，然后将它变成了一个模型表单集。
然后，我们为其创建了一个模型表单，该模型表单App具有一个重写的initApp方法，该方法为模型表单的实例实例化一个 AppOption表单集。
最后，我们使用模型表单创建了一个模型App表单集。
这是保存所有应用程序和应用程序选项的视图
def one(request):
if request.method == 'POST':
formset = AppFormSet(request.POST, prefix="apps") # do some magic to ALSO apply POST to inner formsets
if formset.is_valid(): # do some magic to ALSO validate inner formsets
for form in formset.forms:
# saved App Instances
form.save()
for innerform in form.appoptions_formset:
# saved AppOption instances
innerform.save()
else:
formset = AppFormSet(prefix="apps")
options = Option.objects.all()
return render(
request,
"playground/example/one.html",
{
'formset' : formset,
'options' : options,
}
)
模板
this is a test
<style>
thead td {

height: 100px;
}
.vertical {
-webkit-transform: rotate(-90deg);
-moz-transform: rotate(-90deg);
-ms-transform: rotate(-90deg);
-o-transform: rotate(-90deg);
filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=3);
}
</style>
<form>
<table>
<thead>
<tr>
<td> </td>
<td><p class="vertical">Activate App</p></td>
{% for option in options %}
<td><p class="vertical">{{ option.condition }}</p></td>
<td><p class="vertical">{{ option.option }}</p></td>
{% endfor %}
</tr>

{% for form in formset.forms %}
{% if form.instance.pk %}

<td align="center">{{ form.instance.title }}{{ form.id.as_hidden }}</td>
<td align="center">{{ form.activated }}</td>
{% for optionform in form.appoptions_formset.forms %}
{% if optionform.instance.pk %}

{% endif %}
{% endfor %}
