Question

我使用Django 1.11.10和python 3.6;我想在管理面板中创建Item模型，并在同一页面添加多个File模型，因此我使用TabularInline。问题出在保存File模型之前我需要填写其他一些字段，例如上传文件的size。如果我在课堂上使用admin.ModelAdmin，那么save_model会有效，但不适用于admin.TabularInline。

class Item(models.Model):
    title = models.CharField()

class File(models.Model):
    name = models.CharField()
    size = models.PositiveIntegerField()
    file = models.FileField(upload_to='x/')


----


class FileForm(forms.ModelForm):
    class Meta:
        model = File
        fields = ['name', 'file']

    def clean(self):
        cleaned_data = super().clean()
        file = cleaned_data.get('file')

        self.size = file.size # file.size shows correct result

class FileInline(admin.TabularInline):
    model = File
    form = FileForm

    def save_formset(self, request, form, formset, change):
        logger.info('-- does not get here --')
        formset.save_m2m()

    def save_model(self, request, obj, form, change):
        logger.info('-- does not get here --')
        obj.size = form.size
        super(FileInline, self).save_model(request, obj, form, change)

class ItemAdmin(admin.ModelAdmin):
    inlines = [FileInline]


admin.site.register(Item, ItemAdmin)
