如何将起始序列号传递给Django factory_boy工厂？

factory_boy默认为1表示序列.如何传入一个数字作为不同的起始号码呢？我可以继承_setup_next_sequence()方法,但是如何给它一个变量来使用呢？

# File: models.py
from django.db import models

class Book(models.Model):
    title = models.CharField(max_length=100)

# File: factories.py
from .models import Book
import factory

class BookFactory(factory.Factory):
  FACTORY_FOR = BookModel  
  title = factory.Sequence(lambda n: u'Title #{}'.format(n))

  @classmethod
  def _setup_next_sequence(cls):      
      # Instead of defaulting to starting with number 1, start with starting_seq_num.
      # But how do I set starting_seq_num?
      return starting_seq_num

# File: make_data.py
from factories import BookFactory

# somehow set starting sequence number here?

BookFactory().create()

我正在使用factory_boy 1.2.0(通过pip install factory_boy)
factory_boy代码：https://github.com/dnerdy/factory_boy

解决方法:

除了Rob Bednark的答案

我们可以使用reset_sequence()功能,它将计数器重置为特定值.

# File: make_data.py
import factories

factories.BookFactory.reset_sequence(100)
my_book = factories.BookFactory().create()
print(my_book.title) # Title #100
