python - 如何将起始序列号传递给 Django factory_boy 工厂？

Question

factory_boy 默认为序列 1。如何传递一个数字以用作不同的起始数字？我可以将 _setup_next_sequence() 方法子类化，但我怎样才能给它一个要使用的变量？

# 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)

除了Rob Bednark的回答

我们可以使用 reset_sequence() 函数，它将重置计数器为特定值。

# File: make_data.py
import factories

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