- Firstly import below modules in Python file or Django file .
- 1. csv
- 2. psycopg2
- Now Firstly create a connection with your database below way
- try:
- conn_string="dbname='user database name' user='database user name' host='localhost' password='your user password'"
- print ("Connecting to database\n->%s" % (conn_string))
- conn = psycopg2.connect(conn_string)
- print ("connection succeeded")
- except:
- print ("no connection to db")
- Hope if you insert correctly your database information. It should work.
- Now go next step.
- Now collect your data from csv file below way . I gave an example below
- My CSV data Sctucture was below
- Call 43,234234223,2017/08/08 06:47:21
- Call 44,234234234,2017/08/08 06:47:26
- Call 45,987654443,2017/08/08 06:47:30
- Call 46,Ext.301,2017/08/08 07:01:34
- with open("your file location", newline='') as csvfile:
- spamreader = csv.reader(csvfile, delimiter=',', quotechar='|')
- s = []
- for row in spamreader:
- s.append(row)
- s2 = filter(None, s)
- ids = []
- numbers = []
- dateDtime = []
- for i in s2:
- if i[1] == 'Ext.301':
- continue
- else:
- numbers.append(i[1])
- ids.append(i[0])
- dateDtime.append(i[2])
- idnumber = [i.split(' ')[1] for i in ids]
- date = [i.split(' ')[0] for i in dateDtime]
- time = [i.split(' ')[1]for i in dateDtime]
- t = tuple(zip(idnumber,numbers,date,time))
- # check connection
- cur = conn.cursor()
- cur.executemany("INSERT INTO csv_data (id, call_numbers, call_date,call_time) VALUES (%s,%s, %s, %s)", t);
- # Make the changes to the database persistent
- conn.commit()
- # Close communication with the database
- cur.close()
- conn.close()
- My tuple was look like below. If you try to above data , you must get tuple look like this.
- (('43', '234234223', '2017/08/08', '06:47:21'), ('44', '234234234', '2017/08/08', '06:47:26'),('45', '987654443', '2017/08/08', '06:47:30'))
- executemany means in a time it will execute many tuple data.
- That's all . Thanks
