I have a django view with html template with a form and a few buttons. When one of the buttons is pressed it sends a get request with a query param and depending on this param I render the page again but with different json paramethers. However I can’t return the webpage with a second return.
This is the important code of the view for the question. I also tried this without return, but it doesn’t work either. I tried using JsonResponce, but no success:
def card(request):
cur_rk = 0
if request.method == 'GET':
if request.GET.get('C', '') == '-1':
q1 = "SELECT MAX(RK) AS L_RK FROM B_DATA;"
with connection.cursor() as cursor:
cursor.execute(q1)
val = cursor.fetchall()
cur_rk = val[0][0]
return render(request, "card.html", get_db_data(cur_rk))
return render(request, "card.html", get_db_data(cur_rk))
Here is the html code if it might help you:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Create new card</title>
