       # Splicing the root directory and the created template file template is a template folder created by yourself, storing html filesof'DIRS': [os.path.join(BASE_DIR,'template')],

4. Write model class----write in models.py in app

   from django.db import models# Define the book model classclass Book(models.Model):# Title Price Quantity Aliasname = models.CharField(max_length=30,verbose_name="book title")# Up to 5 digits of which 2 are decimalsprice = models.DecimalField(max_digits=5,decimal_places=2,verbose_name="price")# IntegerField cannot write max_lengthnum = models.IntegerField(verbose_name="number")# define metaclassclass Meta:verbose_name_plural = "Books"db_table = "book" # Specify the generated table namedef __str__(self):# Return the description of the objectreturn self.name
