我不确定你为什么要手工做这么多工作。以下是您需要做的事情：

# forms.py
from django import forms
from your_app.models import Entry

class EntryForm(forms.ModelForm):

    class Meta:
        model = Entry


# views.py
from django.shortcuts import render
from your_app.forms import EntryForm

def ins(request):
    form = EntryForm(request.POST or None)
    if request.method == 'POST' and form.is_valid():
        form.save()

    return render(request, 'homepage/index.html', {'form': form})


# index.html

{# code shortened for demonstration purposes #}

<form action="." method="post" enctype="application/x-www-form-urlencoded">
    {{ form.as_table }}
    {% csrf_token %}
    <button type="submit">Insert</button>
</form>

直接从request.POST字典中提取表单值而不通过表单进行验证是一个可怕的想法 - 请不要这样做。
