在Django中保存到模型后返回主键 [英] Return Primary Key after saving to a model in Django

问题描述

我看过文档

I've seen the documentation here and several similar stack Overflow posts, but after saving my form I'm still unable to return the ID/PK of that new model. It keeps telling me 'ProposalForm' object has no attribute 'id' How can I return the ID right after saving?

这是视图:

def proposal_create_view2(request):
        if request.method == 'POST':
            form = ProposalForm(data=request.POST)
            if form.is_valid():
                form.save()
                response = {}
                response['proposalID'] = form.id
                return response

推荐答案

my_saved_model = my_model_form.save()

my_saved_model = my_model_form.save()

打印my_saved_model.pk

print my_saved_model.pk

def proposal_create_view2(request):
    if request.method == 'POST':
        form = ProposalForm(data=request.POST)
        if form.is_valid():
            mysaved_model = form.save()
            response = {}
            response['proposalID'] = mysaved_model.id #or .pk
            return render(request , 'my_template_file.html' , response) 

            #return response statement is NOT valid as you need to return an HttpResponse not a dict

查看Django Docs在HttpResponses上
