How to work with models in django(Important)-1

let us take some Example ie., ....

from django.db import models

class Blog(models.Model):
    name = models.CharField(max_length=100)
    tagline = models.TextField()

    def __str__(self):              # __unicode__ on Python 2
        return self.name

class Author(models.Model):
    name = models.CharField(max_length=50)
    email = models.EmailField()

    def __str__(self):              # __unicode__ on Python 2
        return self.name

class Entry(models.Model):
    blog = models.ForeignKey(Blog)
    headline = models.CharField(max_length=255)
    body_text = models.TextField()
    pub_date = models.DateField()
    mod_date = models.DateField()
    authors = models.ManyToManyField(Author)
    n_comments = models.IntegerField()
    n_pingbacks = models.IntegerField()
    rating = models.IntegerField()

    def __str__(self):              # __unicode__ on Python 2
        return self.headline 

================

here we will see what acutally here we wrote

1. to create database we need to use class 

ie., 

Syntax: 

class classname(models.Model):

     column_name=models.datatype(attributes)

     def __str__(self):

         return self.column_name

2. so here the data type are 

CharField()

-----------

attribute will be maxlength 

 
 
ForeignKey(), ManyToManyField() 

--------------

attribute will be class name

ImageField

--------------- 
 

attribute will be upload_to="images/"

DateTimeField

---------------- 
auto_now_add =True  

Other

----- 

IntegerField()
TextField()
EmailField()
DateField()
