I am trying to send a lot of GET requests to my back-end, but can not understand what happening here
viws.py:
from django.views.generic import TemplateView
class HomePageView(TemplateView):
template_name = "pages/home.html"
class AboutPageView(TemplateView):
template_name = "pages/about.html"
class TestPageView(TemplateView):
template_name = "pages/test.html"
def get(self, request, *args, **kwargs):
num = request.GET.get('num')
result = f"test {num} - status: ok"
return HttpResponse(result)
test.html:
{% load static %}
{% block title %}Test{% endblock title %}
{% block content %}
<!DOCTYPE html>
<html>
<body>
<h2>Test server</h2>
<form id="function_form">
<button type="submit" id="start_btn">Start</button>
</form>
<div id="result"></div>
<script>
document.getElementById("function_form").addEventListener("submit", function (event) {
event.preventDefault();
for (let i = 1; i <= 1000; i++) {
fetch('/test/?num=' + i)
.then(response => response.text())
.then(data => {
document.getElementById("result").innerHTML += data + "<br>";
});
}
});
</script>
</body>
</html>
{% endblock content %}
urls.py:
from django.urls import path
from .views import HomePageView, AboutPageView, TestPageView
urlpatterns = [
path("", HomePageView.as_view(), name="home"),
path("about/", AboutPageView.as_view(), name="about"),
path("test/", TestPageView.as_view(), name="test"),
]
After I path to /test/ or, for example, /test/?num=2 I receive a page which has only "test 2 - status: ok" and nothing common with test.html.
Why on /test there is no content that I expected to see?
The problem is that you send a HttpResponse as answer to your get request.
def get(self, request, *args, **kwargs):
num = request.GET.get('num')
result = f"test {num} - status: ok" # here you define the string that you see as http output
return HttpResponse(result) # this is the plain response type that you are sending
Utilize the render function!
from django.shortcuts import render
class TestPageView(TemplateView):
template_name = "pages/test.html"
def get(self, request, *args, **kwargs):
# num = request.GET.get('num')
# result = f"test {num} - status: ok"
return render(self.request, self.template_name, context=self.get_context_data())
render accepts arguments: First the request, second the template, third the context. Context is defined in the method get_context_data() for class based views. You could also just pass a dictionary there with your variables.
Actually my solution above is the default of the TemplateView. You just have to get rid of "defining the response as HttpResponse("some text")" yourself. So this should work as fine:
class TestPageView(TemplateView):
template_name = "pages/test.html"
# delete entire get method
