问题 I am using django-import-export 1.0.1 with admin integration in Django 2.1.1.

问题 I'm attempting to create a formset for the following models: class Category(models.Model): name = models.CharField(max_length=100, unique=True) description = models.TextField(null = True, blank=True) class Recipe(models.Model): title = models.CharField(max_length=100) body = models.TextField() user = models.ForeignKey(User) categories = models.ManyToManyField(Category, null = True, blank = True) But any time I try to implement a formset, like so: FormSet = inlineformset_factory(Category,

问题 I'm having a bit of trouble grasping how to do this. I've put my best effort into searching Google without any luck.

问题 How can I make this loop to print form fields where XXXXXXXX is the value of ticket.id? {% for ticket in zone.tickets %} {{ ticket.id }}: {{ form.ticket_count_XXXXXXXX }} {% endfor %} So the output to be something like this... 1: <input ... name="ticket_count_1"> 10: <input ... name="ticket_count_10"> 12: <input ... name="ticket_count_12"> 3: <input ... name="ticket_count_3"> 回答1: You can't pass arguments in the django template, so no.

问题 In my Django app I have several different forms, which are similar in style. To not repeat myself over and over again, I try to rewrite the default form settings.
