With <code>asyncio</code>, you can run multiple <code>async</code> functions in background concurrently and asynchronously in Django view as shown below.
<pre class="lang-py prettyprint-override"><code># &quot;store/views.py&quot;

import asyncio
from django.http import HttpResponse

async def test1(num):
 print(&quot;Test1&quot;)
 return num + 1

async def test2(num):
 print(&quot;Test2&quot;)
 return num + 1

async def test(request):
 result1, result2 = await asyncio.gather(test1(2), test2(3))
 total = result1 + result2
 print(total) # 7
 return HttpResponse(total) # Return 7
</code></pre>
This is the result below:
<pre class="lang-none prettyprint-override"><code>Test1
Test2
7
[03/Nov/2022 15:12:30] &quot;GET /store/test/ HTTP/1.1&quot; 200 1
</code></pre>
And, with threads, you can also run multiple functions in background concurrently in Django view as shown below.
<pre class="lang-py prettyprint-override"><code># &quot;store/views.py&quot;

from threading import Thread
from django.http import HttpResponse

def test1(num, r):
 print(&quot;Test1&quot;) 
 r[0] = num + 1

def test2(num, r):
 print(&quot;Test2&quot;)
 r[0] = num + 1

def call_tests_view(request):
 result1 = [None] # Here
 result2 = [None] # Here
 thread1 = Thread(target=test1, args=(2, result1), daemon=True)
 thread2 = Thread(target=test2, args=(3, result2), daemon=True)
 thread1.start()
 thread2.start()
 thread1.join()
 thread2.join()
 total = result1[0] + result2[0]
 print(total) # 7
 return HttpResponse(total) # Return 7
</code></pre>
This is the result below:
<pre class="lang-none prettyprint-override"><code>Test1
Test2
7
[03/Nov/2022 15:16:45] &quot;GET /store/test/ HTTP/1.1&quot; 200 1
</code></pre>

I have Django project with one view. When I refresh page I want to call some function which is very complicated and take same time to execute. How and what is the best way to do it in backround?
<pre><code>import time
import psycopg2
from django.http import HttpResponse

def long_time_function(sec):
 time.sleep(sec)
 print('DONE')

def index(request):
 
 long_time_function(100)

 return HttpResponse('INDEX page')
</code></pre>
<hr />
There is some built in solutions to do that or I need to run this function with thread or multiprocessing and set Deamon = True ?
