Question

我的表格中的值似乎没有在我的表格中正确插入。以下是我的代码： -

## my Forms.py ##

class AerialPhotoForm(forms.ModelForm):
    class Meta:
        model = AerialFoto
            fields = ['year_id', 'scale_id', 'index_id', 'location_id', 'size']

## my Views.py ##

if request.method == 'POST':
    form = AerialPhotoForm(request.POST)
        if form.is_valid():
    form.save()

## my Models.py ##

class AerialFoto(models.Model):
    AerialFoto_id = models.AutoField(primary_key=True)
    index_id = models.ForeignKey(No_index, null=True, blank=True)
    scale_id = models.ForeignKey(Scale, null=True, blank=True)
    location_id = models.ForeignKey(Location, null=True, blank=True)
    year_id = models.ForeignKey(Year, null=True, blank=True)
    file_directory = models.CharField(max_length=255)
    size = models.DecimalField(max_digits=19, decimal_places=2, blank=True, null=True)
    gsd = models.CharField(max_length=7)

我得到的结果是： -

要查看对象的详细表达式，您需要在模型中定义__unicoide__（或__str__ if python 3.x）方法：

class Location(models.Model):

    ...
    name = models.CharField.....

    def __unicode__(self):  # or __str__ if python 3
        return self.name  # assuming you have a name field, you can use any string field.
        # You could return any string here to test
        # e.g. return 'This is my object'

No_Index，Scale和Year模型也是如此。
