Django can't find table, that exists in postgreSQL database - django

Question

I'm new to database programming, apologies if I ask something simply.
I newly add few tables into my DB use Django model and migrations, now I'm using python bring data and print on scripts
Now to point of my error:
DB is connected successfully
Failed to execute database program
relation "cgi_limit" does not exist
LINE 1: SELECT * FROM CGI_limit
^
connection of DB had close successfully
now I check twice on naming. I try others tables such as auth_user and its was able print the table contents and I check to see if table exit in my DB as shown below;
Farm=# SELECT * FROM pg_tables;
schemaname | tablename | tableowner | tablespace | hasindexes | hasrules | hastriggers | rowsecurity
public | django_session | FAT | | t | f | f | f
public | auth_permission | FAT | | t | f | t | f
public | auth_user_user_permissions | FAT | | t | f | t | f
public | auth_user | FAT | | t | f | t | f
public | django_admin_log | FAT | | t | f | t | f
public | CGI_ambient | FAT | | t | f | f | f
public | CGI_tank_system | FAT | | t | f | f | f
public | CGI_limit | FAT | | t | f | f | f
I my python code that render the DB;
#import liberys
import psycopg2 as pg2
from datetime import timedelta, datetime, date
############################################
# Function codes
def getDbConnection():
#Get Database connection
try:
connection =pg2.connect(user='FAT',
password='*******',
host='',
port='5432',
database='Farm')

return connection
except(Exception, pg2.DatabaseError) as error:
print("Failed to connect to database")
def closeDbConnection(connection):
#Close Database connection
try:
connection.close()
print("connection of DB had close succefully")
except(Exception, pg2.DatabaseError) as error:
print("Failed to close database connection")
def DisplayDBdata():
try:
connection = getDbConnection()
cursor = connection.cursor()
query = 'SELECT * FROM "CGI_limit"'
cursor.execute(query,)
records = cursor.fetchall()
for row in records:
print("date: = ", row[1])
except(Exception, pg2.DatabaseError) as error:
print("Failed to execute database program")
print(error)
finally:
closeDbConnection(connection)

I'm stump of what I should do. I did some google search and result only naming

Postgres does not like capitalized table names. You will need to put the table name in quotes to make it work. I would recommend sticking with lowercase names.
query = 'SELECT * FROM "CGI_limit"'
