Django Builds online education platform _day_2: New users app to write models extension user table

1. Create an app using Pycharm

Tools toolbar running Run manage.py Task

Input: Startapp Users

2. To see the Default Users table Auth_User that Django generates, and to see if the fields meet the needs, you cannot write models custom user table Inheritance Auth_User fields in users/models.py.

 fromDjango.dbImportModels#Abstractuser contains the default generated user field for Django fromDjango.contrib.auth.modelsImportAbstractuser#Create your models here.classuserprofile (abstractuser):"""inherit the Abstractuser class, add a database field from a new class of meanings"""    #default= ' default is emptyNick_name = models. Charfield (max_length=50, Verbose_name=u'Nickname', default="')    #null=true, Blank=true allows users not to fill inBirday = models. Datefield (verbose_name=u'Birthday', Null=true, blank=True)#Choices Property, which provides the selected data, where sex is only male and femaleGender = models. Charfield (max_length=5, choices= ('male','male'), ('female','female')), default='female', Verbose_name=u'Sex')#SexAddress = models. Charfield (max_length=100, Default=u"', Verbose_name=u'Address') Mobile= Models. Charfield (max_length=11, Null=true, Blank=true, Verbose_name=u'Phone number')    #upload_to Specify Avatar Upload folderImage = Models. ImageField (upload_to='image/%y/%m', Default=u'Image/default.png', Verbose_name=u'Avatar', max_length=100)    classMeta:verbose_name= R'User Information' #别称verbose_name_plural=verbose_name #单数别称def __unicode__(self):"""overloaded functions to enable custom strings to be printed"""        returnSelf.username

3. Registering apps and overloaded methods in mxonline/settings.py

#application DefinitionInstalled_apps= [    'Django.contrib.admin',    'Django.contrib.auth',    'Django.contrib.contenttypes',    'django.contrib.sessions',    'django.contrib.messages',    'Django.contrib.staticfiles',    'Users',#Register App]#overloaded Auth_user_model method, app name + Custom models class nameAuth_user_model ='users. UserProfile'

4, the operation of the project, the following error occurred, the reason is that we use the ImageField in the custom class, need to install the Pillow image processing module:

Installing Pillow:pip install pillow, rerun, report the following error because the database does not have the users table

To create the Users table:

Tools toolbar running Run manage.py Task

Input: Makemigrations Users

Input: Migrate Users

Input: Yes

View database table input Users_userprofile created successfully

Run the project again, success
