如何使用django模型使用enter keyword to database逐行保存字符域？

from django.db import models

class Keyword(models.Model):
    keyword = models.CharField(max_length=255)

python manage.py makemigrations
python manage.py migrate

from .models import Keyword

def save_keyword(request):
    if request.method == 'POST':
        keyword = request.POST.get('keyword')
        Keyword.objects.create(keyword=keyword)
        # 或者使用以下方式保存
        # keyword_obj = Keyword(keyword=keyword)
        # keyword_obj.save()

<form method="POST" action="{% url 'save_keyword' %}">
    {% csrf_token %}
    <input type="text" name="keyword">
    <button type="submit">保存</button>
</form>
