Save_as does not handle manytomany field gracefully

[karthikbgl]

Lets say there is a validation error on the object to be cloned, if the object has any many to many fields, it loses the reference to those.

Hi @karthikbgl,

I couldn't reproduce this bug. I added a couple tests for m2m fields, please see afaae0d9467c1af6777ceb55b8e7cdb2b01bdb3e. Did I cover your bug or is it another scenario?

Hi @igorsobreira

Thank you for the quick response. My scenario is:

class ModelAConfigInline():
    model = ModelAConfig

class ModelAAdmin(ClonableModelAdmin):
    inlines = [ModelAConfigInline]

and the model relationships:

class ModelAConfig(models.Model):
    premiums = models.ForeignKey(PremiumSet, null=True, blank=True)
    campaign = models.ForeignKey(ModelA)
    #Basically, the reverse foreign key relationship. 

My apologies for not giving enough details upfront.

I'm a bit confused. You mentioned Many to Many relationship in the issue but this code sample has a One to Many.

When you are editing a ModelA object and click Clone, all django-modelclone does is give you a form pre-filled so you can create a new ModelA; and if the original ModelA had inlines, that is ModelAConfigs referencing it, your clone form will have pre-filled inline forms to create new ModelAConfig objects, that will reference the new ModelA.
