Django CharField not defined

from django.db import models

class Pet(models.Model):
    SEX_CHOICES = [('M','Male'), ('F', 'Female')]
    name = CharField(max_length=100)
    submitter = CharField(max_length=100)
    species = CharField(max_length=30)
    breed = CharField(max_length=30, blank=True)
    description = models.TextField()
    sex = models.CharField(choices=SEX_CHOICES, max_length=1, blank=True)
    submission_date = models.DateTimeField()
    age = models.IntegerField(null=True)
    vaccinations = models.ManyToManyField('Vaccine', blank=True)


class Vaccine(models.Model):
    name = models.CharField(max_length=50)

With this code I am getting command line error when running "python manage.py makemigrations". name "CharField" is not defined.

How to fix it.

You should add CharField class to module imports, ie,

from django.db import models
from django.db.models import CharField



But, this isn't a right way to import modules in your projects. So change your models.py as follows,

from django.db import models

class Pet(models.Model):
    SEX_CHOICES = [('M','Male'), ('F', 'Female')]
    name = models.CharField(max_length=100)
    submitter = models.CharField(max_length=100)
    species = models.CharField(max_length=30)
    breed = models.CharField(max_length=30, blank=True)
    description = models.TextField()
    sex = models.CharField(choices=SEX_CHOICES, max_length=1, blank=True)
    submission_date = models.DateTimeField()
    age = models.IntegerField(null=True)
    vaccinations = models.ManyToManyField('Vaccine', blank=True)


class Vaccine(models.Model):
    name = models.CharField(max_length=50)

Shouldn't it be like this :

from django.db import models

class Pet(models.Model):
    SEX_CHOICES = [('M','Male'), ('F', 'Female')]
    name = models.CharField(max_length=100)
    submitter = models.CharField(max_length=100)
    species = models.CharField(max_length=30)
    breed = models.CharField(max_length=30, blank=True)
    description = models.TextField()
    sex = models.CharField(choices=SEX_CHOICES, max_length=1, blank=True)
    submission_date = models.DateTimeField()
    age = models.IntegerField(null=True)
    vaccinations = models.ManyToManyField('Vaccine', blank=True)


class Vaccine(models.Model):
    name = models.CharField(max_length=50)

You used CharField directly instead of models.CharField in some of your declarations.

This should do:

from django.db import models

class Pet(models.Model):
    SEX_CHOICES = [('M','Male'), ('F', 'Female')]
    name = models.CharField(max_length=100)
    submitter = models.CharField(max_length=100)
    species = models.CharField(max_length=30)
    breed = models.CharField(max_length=30, blank=True)
    description = models.TextField()
    sex = models.CharField(choices=SEX_CHOICES, max_length=1, blank=True)
    submission_date = models.DateTimeField()
    age = models.IntegerField(null=True)
    vaccinations = models.ManyToManyField('Vaccine', blank=True)


class Vaccine(models.Model):
    name = models.CharField(max_length=50)
