当尝试将迁移应用于Django 1.9.1项目时，我得到：
ValueError: Unhandled pending operations for models:
casos.caso (referred to by fields: oferta.Columna.casos, oferta.Columna_casos.caso, oferta.Producto.banners_casos, oferta.Producto.casos_de_exito, oferta.Producto_banners_casos.caso, oferta.Producto_casos_de_exito.caso)
项目运行正常，没有错误。 我已成功将所有迁移应用于“ casos ”和“ oferta ”，当我在其他应用上运行迁移时，这会显示出来。
这是我从django 1.4更新的遗留项目。我在'oferta'和'casos'之间有一个循环的迁移依赖问题，我设法通过将'oferta'的引用移到'casos'中的第二次迁移来解决。
要完整的追溯和迁移：
