将字典保存到模型对象

Question

I have a dictionary like this one:

{'company_name': 'Google', 'title': 'headline', ...}

I know that i can store the values using this way:

user = User(company_name=data_db_form['company_name'], title=data_db_form['title']...)

However this is not good if I have many form fields.

There is any way to do this without hard code all the maps? The key value of the dictionary is the same of his model.

Answer 1

You can use the following:

user = User(**data_db_form)

Here is the full example:

class User():
    def __init__(self, company_name='unknown', title='unknown'):
        self.company_name = company_name
        self.title = title

data_db_form = {'company_name': 'Google', 'title': 'headline'}

user = User(**data_db_form)

print user.company_name # prints Google
print user.title        # prints headline

Answer 2

使用for key, value in dic.iteritems():字典，然后在每次迭代中，key中都有company_name ， title等for key, value in dic.iteritems():则有Google ， headline等。
