django - How to convert many to many field to foreign key? -

lets have model class like;

class samplingquery(models.model):    brands = models.manytomanyfield(brand)

after while realize need convert manytomanyfield foreignkey need convert class foreignkey;

class samplingquery(models.model):    brands = models.foreignkey(brand)

is there way without losing data?

thank you

there no simple mechanism, can following:

create new foreignkey (say, brand)
copy existing data brands (by slicing first result since there can multiple manytomany relation) brand
delete field brands
