如何重写模型表单django上的单个项

from django import forms
from .models import YourModel

class YourModelForm(forms.ModelForm):
    your_field = forms.CharField(label='Your Field', max_length=100)

    class Meta:
        model = YourModel
        fields = '__all__'

from django.shortcuts import render
from .forms import YourModelForm

def your_view(request):
    form = YourModelForm()
    form.fields['your_field'].initial = 'Your Initial Value'  # 设置单个项的初始值
    return render(request, 'your_template.html', {'form': form})

<form method="post">
  {% csrf_token %}
  {{ form.your_field.label_tag }}: {{ form.your_field }}  <!-- 渲染单个项 -->
  {{ form.errors.your_field }}  <!-- 渲染单个项的错误信息 -->
  <input type="submit" value="Submit">
</form>
