Can a dictionary be passed to django models on create?
If title
and body
are fields in your model, then you can deliver the keyword arguments in your dictionary using the ** operator.
Assuming your model is called MyModel
:
# create instance of modelm = MyModel(**data_dict)# don't forget to save to database!m.save()
As for your second question, the dictionary has to be the final argument. Again, extra
and extra2
should be fields in the model.
m2 =MyModel(extra='hello', extra2='world', **data_dict)m2.save()
Not directly an answer to the question, but I find this code helped me create the dicts that save nicely into the correct answer. The type conversions made are required if this data will be exported to json.
I hope this helps:
#mod is a django database model instancedef toDict( mod ): import datetime from decimal import Decimal import re #Go through the object, load in the objects we want obj = {} for key in mod.__dict__: if re.search('^_', key): continue #Copy my data if isinstance( mod.__dict__[key], datetime.datetime ): obj[key] = int(calendar.timegm( ts.utctimetuple(mod.__dict__[key]))) elif isinstance( mod.__dict__[key], Decimal ): obj[key] = float( mod.__dict__[key] ) else: obj[key] = mod.__dict__[key] return obj def toCsv( mod, fields, delim=',' ): import datetime from decimal import Decimal #Dump the items raw = [] for key in fields: if key not in mod.__dict__: continue #Copy my data if isinstance( mod.__dict__[key], datetime.datetime ): raw.append( str(calendar.timegm( ts.utctimetuple(mod.__dict__[key]))) ) elif isinstance( mod.__dict__[key], Decimal ): raw.append( str(float( mod.__dict__[key] ))) else: raw.append( str(mod.__dict__[key]) ) return delim.join( raw )
For any model DummyModel
you can use DummyModel.objects.create(**data_dict)
. Does not require save after the create.
