My search form:

 <form class=" my-2 my-lg-0 d-flex flex-row-reverse" method=POST action="{% url 'memes:all' %}" >
        {% csrf_token %}
        <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
      <input class="form-control mr-sm-2" name="search" placeholder="Search" aria-label="Search">
    </form>

My List View:


class MemeListView(ListView):
    model = Meme
    paginate_by = 100
    ordering = ['-created_at']

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['now'] = timezone.now()
        search_value = self.request.GET.get("search", False)
        if search_value:
            memes = Meme.objects.filter(name_contains=search_value)
            objects = Meme.objects.filter(memes).select_related().distinct().order_by('-created_at')[:10]
            context['meme_list'] = objects
            context['search'] = search_value
        return context

My url:

path('', MemeListView.as_view(), name='all'),

error: "GET / HTTP/1.1" 200 4455

Method Not Allowed (POST): /all/

Method Not Allowed: /all/

[01/Feb/2022 19:23:22] "POST /all/ HTTP/1.1" 405 0

I've done almost identical search functionality in my other crud and it seems to work. What's the issue?

A search is normally done through a GET request, not a POST request: POST requests are usually used to create, update and delete entities.

So your form should have method="GET":

<form class=" my-2 my-lg-0 d-flex flex-row-reverse" method="GET" action="{% url 'memes:all' %}">
    …
</form>

Since this is a GET request, it is not necessary to use {% csrf_token %} since cross-site request forgery will not result in creating, updating or removing an entity.
