隐藏django模型字段，并在表单提交时自己生成它

from django.db import models

class MyModel(models.Model):
    name = models.CharField(max_length=100)
    hidden_field = models.CharField(max_length=100, editable=False)  # 设置editable=False使其不在管理后台显示

from django import forms
from .models import MyModel

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = ['name']  # 只包含需要用户输入的字段

from django.shortcuts import render, redirect
from .forms import MyModelForm
from .models import MyModel

def my_view(request):
    if request.method == 'POST':
        form = MyModelForm(request.POST)
        if form.is_valid():
            instance = form.save(commit=False)  # 先不保存到数据库
            instance.hidden_field = generate_hidden_value()  # 自定义函数生成隐藏字段的值
            instance.save()  # 现在保存到数据库
            return redirect('success_url')  # 重定向到成功页面
    else:
        form = MyModelForm()
    
    return render(request, 'my_template.html', {'form': form})

def generate_hidden_value():
    # 这里可以编写生成隐藏字段值的逻辑
    return "自动生成的值"

<form method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">提交</button>
</form>
