Login to webpage from script using Requests and Django

Question

I have written a web application in Django. I need to post some data to a form from a python script. The post (r2) works correctly when login is disabled. I have the request working correctly for the login (r1), but it gives me a 404 error now for the form post (r2). The login doesn't appear to be carried over to the second request. The csrftoken and sessionid are hardcoded for testing because it wasn't recognizing them. Relevant code (url base removed):

url_login='../pecasRunLog/accounts/login/'
url_add_run='../pecasRunLog/model/'+region+'/add_run/'

client = requests.session()
client.get(url_login)
csrftoken = client.cookies['csrftoken']
login_data = {'username':user,'password':password, 'csrfmiddlewaretoken':csrftoken, 'next': '/pecasRunLog/'}
r1=client.post(url_login,data=login_data)

payload={'model_region':region_id,'scendir':scendir, 'mapit_scenario': schema, 'run_name':schema+timestamp, 'run_computer_name':os.environ['COMPUTERNAME'], 'run_computer_ip':get_lan_ip(), 'declared_user':declared_user, 'logged_in_user':getpass.getuser(), 'sd_schema':schema, 'sd_database':database, 'sd_host':get_lan_ip(), 'sd_port':pgport,'mapit_schema':schema, 'mapit_database':database, 'mapit_host':get_lan_ip(), 'mapit_port':pgport,'start_date':start_date, 'start_time':start_time, 'end_date':end_date, 'end_time':end_time,'logged_manually':3, 'csrfmiddlewaretoken':csrftoken, 'sessionid':'jtvv50cs3iyo9bjthbr2diujfmrrlsnf'}
r2=requests.post(url_add_run,payload)

I just face same problem.

Looks like django use diferent url for login post than the login home page.

This code work for me

import requests
URL1='http://localhost:8000/admin/'
URL='http://localhost:8000/admin/login/?next=/admin/'
UN='bino'
PWD='sendhimin'
client = requests.session()

# Retrieve the CSRF token first
client.get(URL1)  # sets the cookie
csrftoken = client.cookies['csrftoken']

login_data = dict(username=UN, password=PWD, csrfmiddlewaretoken=csrftoken)
r = client.post(URL2, data=login_data, headers={"Referer": "foo"})
