从 2 个模型创建表单 python django: [Errno 2] 没有那个文件或目录
create form from 2 models python django: [Errno 2] No such file or directory
我正在尝试使用 python 和 django 从 2 个模型创建一个表单。
下面显示了我的模型：
# Create your models here.
class Action(models.Model):
name = models.CharField("Action name", max_length=50)
keywords = models.CharField("Keywords", max_length=50)
object = models.CharField("Object", max_length=50, blank=True, null=True)
uploadDate = models.DateField("Date", default=get_current_date)
UploadedBy = models.CharField("UploadedBy", max_length=50, default="")
class Image(models.Model):
image = models.FileField(upload_to=get_upload_file_name, default="")
action = models.ForeignKey(Action)
和表格 类：
class ActionForm(ModelForm):
#bind form to Action model
class Meta:
model = Action
fields = ['name','keywords', 'object', 'UploadedBy', 'uploadDate']
class ImageForm(ModelForm):
class Meta:
model= Image
fields =['image']
从 createForm.html 模板创建页面的视图中的代码：
def actioncreate(request):
if request.method == "GET":
#create the object - Actionform
form = ActionForm;
form2 = ImageForm;
#pass into it
return render(request,'app/createForm.html', { 'form':form, 'form2':form2})
elif request.method == "POST":
# take all of the user data entered to create a new action instance in the table
form = ActionForm(request.POST, request.FILES)
form2 = ImageForm(request.POST, request.FILES)
if form.is_valid() and form2.is_valid():
#prepare action model
act = form.save(commit=False)
#set the action_id Foreignkey
act.action_id = form2.save()
act.save()
return HttpResponseRedirect('/actions')
else:
form = ActionForm()
form2 = ImageForm;
return render(request,'app/createForm.html', { 'form':form, 'form2':form2 })
表单模板：
<form method="post" enctype="multipart/form-data">
{% csrf_token %}
<ul>
{{ form.as_ul }}
{{ form2.as_ul }}
</ul>
<button type="submit">Save</button>
<button name="cancel" onclick="navigate({% url 'home' %})">Cancel</button>
</form>
访问页面时表单显示正常，但是提交后出现此错误：
[Errno 2] 没有那个文件或目录
它似乎不喜欢这条线：
act.action_id = form2.save()
最确定创建的模型具有我所指的所有字段，尽管我收到此错误，但前半部分 (ActionForm) 已保存到数据库中，
但不是 imageForm。一些帮助将不胜感激！
