Question

I am beginner to python Django . I have a string in json format , like

jsondict = {"name": "value", "pwd": "pwdvalue", "email": "[e-mail]"}  

i converted it to dict using json.loads(str)

From the above dict, i want to save only name,and pwd and many others except some keys. So, i am doing like this in the views :

u=users(name=jsondict['name'], pwd=jsondict['pwd'])
u.save()

Is my code having good quality ? or do i need to do that in any other way for having good quality .
In my question,automatic or manual in the sense, do i have to insert some dict directly or manullay have to do as i shown in the code ?
Will provide more information if necessary
Thanks

Answer 1

An option you have here is to filter your dict down, and then use ** to unpack it as keyword arguments.

user_fields = {"name", "pwd"}
jsondict= {"name":"value","pwd":"pwdvalue","email":"[e-mail]"}
userdict = {key: value for (key, value) in jsondict.items() if key in user_fields}
u = users(**userdict)

We use a dict comprehension to filter out everything but the values we want (stored in the set user_fields).
