I have a problem, in my work I need to insert a system of likes to published posts but by clicking on the button that should give the post a like, nothing happens and this error comes out..."POST /posts/like/ HTTP/ 1.1" 405 0
views.py
#ajax_required
#require_POST
#login_required
def post_like(request):
post_id = request.POST.get('id')
action = request.POST.get('action')
if post_id and action:
try:
post = Post.objects.get(id=post_id)
if action == 'like':
post.users_likes.add(request.user)
else:
post.users_likes.remove(request.user)
return JsonResponse({'status': 'ok'})
except:
pass
return JsonResponse({'status': 'error'})
urls.py
from django.urls import path, include
from . import views
app_name = 'posts'
urlpatterns = [
path('like/', views.post_like, name='like'),
]
index.html
{% with total_likes=post.users_likes.count users_likes=post.users_likes.all %}
<div class="post-info">
<div>
<span class="count">

{% endfor %}
</div>
{% endwith %}
<p>{{ post.id }}</p>
<a class="normal-text" href="{{ post.get_absolute_url }}">Discover more...</a>

ajax code
<script>
{% block domready %}
$('a.like').click(function(e){
e.preventDefault();
$.post("{% url 'posts:like' %}",
{

I don't understand where the problem is... I thought in the url but I don't think so
From the documentation, it appears that your urls.py is at fault - you define a "like/" pattern, but there's nothing to tell the router that you mean for it to have a "posts/" prefix.
The examples given there explicitly use an include directive to do that, and you do no such thing. Try:
from django.urls import include, path
from . import views
urlpatterns = [
path('posts/', include([
path('like/', views.post_like, name='like'),
# Other posts/... endpoints
])),
# path('users/', include([ ...
]

so i have this html :
{% extends "encyclopedia/layout.html" %}
{% block title %}
{{ title }}
{% endblock %}
{% block body %}
<h1>{{ title }}</h1>
{% autoescape off %}
<p>{{ entry|safe }}</p>
{% endautoescape%}
<br>
<button type="button" name="button">Edit</button>
{% endblock %}
i want the url 'edit' to also get the value of the {{ title}} - instead of 'cat' ..i just used this value to test the rest of the code, but i don`t want to hard code it like that ...
here are my urls.py:
urlpatterns = [
path("", views.index, name="index"),
path("<str:title>", views.title, name="title"),
path("edit/<str:title>", views.edit, name="edit"),
path("error/", views.error, name="error"),
path("new/", views.new, name="new"),
]
this is the code in views.py :
def title(request, title):
entry = util.get_entry(title)
if entry == None:
return redirect("error")
entry_html = md.convert(entry)
return render(request, "encyclopedia/title.html", {
"entry": entry_html
})
def edit(request, title):
if request.method == "POST":
# get the changes from the user
form = EditEntryForm(request.POST)
if form.is_valid():
content = form.cleaned_data["content"]
# save the entry and redirect to the updated page
util.save_entry(title, content)
return redirect("title", title=title)
else:
redirect("edit", title=title)
entry = util.get_entry(title)
form = EditEntryForm(initial={'content': entry})
return render(request, "encyclopedia/edit.html", {
"form": form
})
as i said the code works as intended if i hard code the value of the title ....how do i get {{ title }} in the href url ?
You should just be able to pass it in as:
{% url 'edit' title %}
…or you may need to specify the argument name:
{% url 'edit' title=title %}
See this link in the documentation for more information.
I've been learning Django for like a month so apologies if I'm doing something stupid, but, I'm getting a NoReverseMatch Reverse for 'profile' with arguments '('',)' not found. 1 pattern(s) tried: ['profile/(?P<use>[^/]+)$'] error when trying to render a "profile" page under the url '/profile/[a user's name]', and I'm pretty sure all my paths/patterns are correct?? Here's my code, could someone help me with this? All my other url patterns work fine. This path also worked fine before, I just renamed the "user" variable into "use" and this happened.
urls.py:
urlpatterns = [

I assume you have not changed user foreignkey from Post model. So, I guess your error is from this line:
<h5>{{post.use}}</h5>
So, it should be like:
<h5>{{ post.user }}</h5>

Thanks in advance
Your "/post/like" URL is matching the URL pattern for CategoryListView, since it is "post" plus a string.
As you have done with the post detail view, bring the pattern for the like view earlier in the list of URLs so that it matches first.
I am encountering the following error when trying to set DetailView for each of the post in my postlist:
NoReverseMatch at /blog/post-list/ Reverse for 'postdetail' with
keyword arguments '{'id': ''}' not found. 1 pattern(s) tried:
['blog\/post-list/(?P\d+)/$']
Here the code:
views.py
def PostList(request):
postlist = Post.objects.all()
context = {
"postlist":postlist
}
template_name = "postlist.html"
return render(request,template_name,context)
def PostDetail(request,id):
post = get_object_or_404(Post,id=id)
context = {

template_name = "postdetail.html"

Does anybody know how to solve this?
I'm trying to build a little django "board" app for my classmates.
But I'm getting this error which I can't find a way around.
I presume it has to be something to do with template rendering, but I don't know what the problems is. It was working fine until I made some modifications to the views & template below. Even after when I undid all the changes I made, it stopped working and returned the same error.

From the traceback I find that the board.id you provide in url tag in the template is empty, and in fact, you haven't specified it in your context.
