设置MyForm(data=data)时"user_id“为空(Django)

# 确保data字典中有'user_id'
data = {'user_id': 1}  # 示例数据
form = MyForm(data=data)

from django import forms
from .models import YourModel

class MyForm(forms.ModelForm):
    class Meta:
        model = YourModel
        fields = ['user_id', ...]  # 确保'user_id'包含在内

from django.db import models

class YourModel(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)  # 假设关联到Django的User模型

def your_view(request):
    if request.method == 'POST':
        form = MyForm(request.POST)
        if form.is_valid():
            # 处理表单数据
            ...
    else:
        form = MyForm()
    return render(request, 'your_template.html', {'form': form})

class MyForm(forms.ModelForm):
    def clean_user_id(self):
        user_id = self.cleaned_data['user_id']
        # 进行验证或其他处理
        return user_id
