我的观点：

@login_required
def editdoctorprofile(request, person_id):
    person_id = int(person_id)
    doc = DirectoryDoctors.objects.get(num = person_id)
    msg =''
    if request.method == 'POST':
        print("POST details", request.POST)
        form = DirectoryDoctorsForm(request.POST)
        if form.is_valid():
            print("Form is valid.")
            username = request.POST.get('username')
        else:
            msg = "Invalid details."
            print(msg)
    else:
        form = DirectoryDoctorsForm(instance=doc)

    return render(
        request, 'app/editdoctor.html', {

当显示此页面时，例如，对于pk为175的查询集，将无法正确显示表单字段血型。它显示值“ -------”

但是如果在django shell上，我会这样做：

>>> from app.models import DirectoryDoctors,DirectoryHospital
>>> DirectoryDoctors.objects.get(pk=175)
<DirectoryDoctors: Mike Dewey, Deputy Director, Deputy Directorate Angamaly, Angamaly>
>>> DirectoryDoctors.objects.get(pk=175).bloodgroup
'A+'
>>>

为什么仅此字段不能正确显示？

Answer 1

该字段似乎无效。

您将字段bloodgroup的首选定义为：

bloodgroup_choices = (
    ('apos', 'A+'),
    ...
)

但是在打印值时，它显示A+（如您向我们显示的那样）：

>>> DirectoryDoctors.objects.get(pk=175).bloodgroup
'A+'

，但小部件必须为apos才能以HTML格式识别它

如果您尝试对数据进行尝试，则此方法调用应突出显示该问题：

>>> DirectoryDoctors.objects.get(pk=175).get_bloodgroup_display()

仅一个表单字段无法显示数据库中的值
