Django Image field doesn't update image - django

Question

I recently got a problem that my django image field in my django app doesn't update the image after pressing "Post". In admin panel everything works fine. Maybe I missed something... Let me know.
models.py
from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
from django.urls import reverse
class Post(models.Model):
title = models.CharField(max_length=200)
content = models.TextField()
date_posted = models.DateTimeField(default=timezone.now)
author = models.ForeignKey(User, on_delete=models.CASCADE)
categories = models.ManyToManyField('Category', related_name='posts')
image = models.ImageField(upload_to='images', default="images/None/no-img.jpg")
def __str__(self):
return self.title
def get_absolute_url(self):
return reverse('post-detail', kwargs={'pk': self.pk})
class Category(models.Model):
name = models.CharField(max_length=20
)
views.py
from django.shortcuts import render, get_object_or_404
from django.contrib.auth.mixins import LoginRequiredMixin, UserPassesTestMixin
from .models import Post
from django.contrib.auth.models import User
from django.views.generic import ListView, DetailView, CreateView, UpdateView, DeleteView
def home(request):
content = {
'posts': Post.objects.all()
}
return render(request, 'blog/home.html', content)
def blog_category(request, category):
posts = Post.objects.filter(categories__name__contains=category).order_by('-date_posted')
content = {
'category': category,
'posts': posts
}
return render(request, 'blog/blog_category.html', content) #<--(didn't add content block) bug found 05.11.19
def upload_pic(request):
if request.method == 'POST':
form = ImageUploadForm(request.POST, request.FILES)
if form.is_valid():
m = ExampleModel.objects.get(pk=course_id)
m.model_pic = form.cleaned_data['image']
m.save()
return HttpResponse('image upload success')
return HttpResponseForbidden('allowed only via POST')
...
class PostCreateView(LoginRequiredMixin, CreateView):
model = Post
fields = ['title', 'content', 'categories', 'image']
def form_valid(self, form):
form.instance.author = self.request.user
return super().form_valid(form)
class PostUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView):
model = Post
fields = ['title', 'content', 'categories', 'image']
def form_valid(self, form):
form.instance.author = self.request.user
return super().form_valid(form)
I just have recently added Category and Image section in my web-application, the Category section works fine, but the image field just post default even if I'm selecting the current image. In the admin field it works well, so I decided to ask community about this annoying problem.

Answer 1

Make sure the form in your template has enctype set correctly:
Note that request.FILES will only contain data if the request method was POST and the that posted the request has the attribute enctype="multipart/form-data". Otherwise, request.FILES will be empty.
