解决方案
我想你必须调用 is_valid ，即使您100％确定表单有效：
如果modelformset.is_valid（）：
modelformset.save（）
I'm trying to save a formset but I keep getting
list_ = super(MultiValueDict, self).__getitem__(key)
KeyError: 'form-0-id'
During handling of the above exception, another exception occurred:
...
django.utils.datastructures.MultiValueDictKeyError: "'form-0-id'"
modelformset.forms raises the same error.
Here's a question that seems very close, but adding {{form.id}} right before {%for field in form.visible_fields %} does not seem to help.
There is an autogenerated id field in the database table, but not specified explicitly in the model (not sure if that's relevant). id does not appear in any of the forms code or fields or model code. id is only a database column automatically generated by migrate.
Here's the view that I post to:
views.py
def list_page(request, list_id):
image_path = get_image_path(list_id)
ordered_men = OrderedTable.objects.filter(list_id=list_id)
ordered_men = list(enumerate(
sorted(ordered_men, key=str)
))
print(f'there are {len(ordered_men)} men')
OrderedManInputFormSet = modelformset_factory(
OrderedManInput,
fields=fields,
form=OrderedManInputForm, extra=0)
ordered_man_input_formset = OrderedManInputFormSet(
form_kwargs={
'choices': ordered_men,
}
)
return render(
request, 'collector/list.html',
{
'list_id': list_id,
'image_path': image_path,
'formset': ordered_man_input_formset,
}
)
def submit(request, list_id):
OrderedManInputFormSet = modelformset_factory(
OrderedManInput,
form=OrderedManInputForm,
fields=fields,
extra=0,
)
modelformset = OrderedManInputFormSet(request.POST)
print('testing validity')
if modelformset.is_valid():
print('saving')
modelformset.save()
return HttpResponseRedirect(
reverse('collector:thanks')
)
def thanks(request):
return render(request, 'collector/thanks.html')
forms.py
class OrderedManInputForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(OrderedManInputForm, self).__init__(args, kwargs)
if 'choices'in kwargs:
# This works
self.fields['full_name'] = forms.ChoiceField(
choices=[('', ' ')] + kwargs['choices'],
required=False
)
class Meta:
model = OrderedManInput
widgets = {}
text_fields = [
...
]
boolean_fields = [
...
]
widgets.update({
field: forms.TextInput()
for field in text_fields
})
widgets.update({
field: forms.CheckboxInput()
for field in boolean_fields
})
fields = text_fields + boolean_fields
labels = {
...
}
Here's the template that does the posting:
<form action="{% url 'collector:submit' list_id %}" method="POST" enctype="multipart/form-data">
{% csrf_token %}
{{ formset.management_form }}
<table id="id_data_table">
{% for form in formset %}
{{form.id}}
{% if forloop.first %}
<thead><tr>
{% for field in form.visible_fields %}
<th>{{ field.label|capfirst }}</th>
{% endfor %}
</tr></thead>
{% endif %}
<tr>
{%for field in form.visible_fields %}
<td>
{{field}}
</td>
{%endfor%}
</tr>
{% endfor %}
</table>
<p/>
<div class="div-submit">
<input type="submit"/>
</div>
</form>
so each row is a form and each column a field:

testing validity comes from this which I added in response to a proposed answer below.
print('testing validity')
if modelformset.is_valid():
print('saving')
modelformset.save()

解决方案
I think you have to call is_valid before saving the formset, even if you are 100% sure the forms are valid:
if modelformset.is_valid():
modelformset.save()
