Recently, I've been working on developing a like system similar to Instagram's using Django and Ajax. However, after completing the code, I encountered a frustrating error message that read "Post matching query does not exist." Despite thoroughly reviewing my code, I haven't been able to identify the issue. I suspect the problem may lie within the views.py file, as the traceback points to a specific line there. How can I troubleshoot and resolve this error?
models.py
class Post(models.Model):
text = models.CharField(max_length=200)
user = models.ForeignKey(User, on_delete=models.CASCADE, default='username')
liked = models.ManyToManyField(User, default=None, blank=True, related_name='liked')
def __str__(self):
return str(self.id)
views.py (includes upload functionality, displaying home content, handling post likes/unlikes, and serializing for non-reloading)
def upload(request):
... // (upload function code here)
def home(request):
... // (home function code here)
def like_post(request):
... // (like_post function code here)
def home_serialized(request):
... // (home_serialized function code here)
urls.py
urlpatterns = [
... // (URL patterns defined here)
]
home.html
... // (Home page HTML template code here)
traceback
