This is my post app's urls.py file. Just to inform, I have 3 apps namely posts,groups,userAuth.
from django.conf.urls import url
from django.urls import path
from django.conf import settings
from django.conf.urls.static import static
from . import views
app_name='posts'
urlpatterns = [
url(r"^$", views.PostList.as_view(), name="all"),
url(r"new/in/(?P<pk>\d+)/$", views.CreatePost.as_view(), name="create1"),
url(r"comment/in/(?P<pk>\d+)/$", views.CreateComment.as_view(), name="create2"),
url(r"by/(?P<username>[-\w]+)/$",views.UserPosts.as_view(),name="for_user"),
url(r"by/(?P<username>[-\w]+)/(?P<pk>\d+)/$",views.PostDetail.as_view(),name="single"),
url(r"comment/delete/(?P<pk>\d+)/$",views.DeleteComment.as_view(),name="delete_comment"),
url(r"delete/(?P<pk>\d+)/$",views.DeletePost.as_view(),name="delete"),
]
if settings.DEBUG:
urlpatterns += static(settings.MEDIA_URL,
document_root=settings.MEDIA_ROOT)
This is post_detail.html, the template in which i am trying to render images(line 8) -
{% extends "posts/post_base.html" %}
{% block content %}
<div class="col-md-8">
<div class="post media ">
<div class="post media list-group-item" style="margin-top: 9px;"><h3 class="title list-group-item-heading" style="color: black !important; margin-bottom: 10px;font-size: large;">{{ post.question }}</h3></div>
<div class="post media list-group-item" style="margin-top: 9px;"><h3 class="title list-group-item-heading" style="color: black !important; margin-bottom: 10px !important; font-size: medium;">{{ post.description_html|safe }}</h3></div>
///line 8 <img src="{{MEDIA_URL}}/pics/{{ post.picture }}" class="img-responsive" style="width: 100%; float: left; margin-right: 10px;" alt="heyy"/>
<div class="media-body">
<h5 class="media-heading" style="margin-top: 7px;">
<span class="username">#{{ post.user.username }}</span>
<time class="time">{{ post.created_at }}</time>
</h5>
the uploading part works perfectly as i got pics/download.jpg on printing {{ post.picture }} on the template instead of line 8
This is my models.py of posts app-
from django.conf import settings
from django.urls import reverse
from django.db import models
import misaka
from groups.models import Group
from django.contrib.auth import get_user_model
User = get_user_model()
class Post(models.Model):
user = models.ForeignKey(User, related_name="posts",on_delete=models.CASCADE)
created_at = models.DateTimeField(auto_now=True)
question = models.CharField(max_length=255)
# question_html = models.TextField(editable=False)
description=models.TextField(blank=True, default='')
description_html = models.TextField(editable=False)
picture=models.ImageField(upload_to='pics',blank=True)
group = models.ForeignKey(Group, related_name="posts",null=True, blank=True,on_delete=models.CASCADE,)
def __str__(self):
return self.question
def save(self, *args, **kwargs):
self.question_html = misaka.html(self.question)
self.description_html = misaka.html(self.description)
super().save(*args, **kwargs)
def get_absolute_url(self):
return reverse(
"posts:single",
kwargs={
"username": self.user.username,
"pk": self.pk
}
)
class Meta:
ordering = ["-created_at"]
unique_together = ["user", "question"]
class Comment(models.Model):
post = models.ForeignKey(Post, related_name='comments',on_delete=models.CASCADE)
created_at = models.DateTimeField(auto_now=True)
comment = models.TextField()
text_html = models.TextField(editable=False)
user = models.ForeignKey(User, related_name="comments",on_delete=models.CASCADE)

self.text_html = misaka.html(self.comment)
super().save(*args, **kwargs)
def get_absolute_url(self):
# return reverse("posts:single" , kwargs={"slug": self.slug})
return reverse("posts:single" , kwargs={"username":self.post.user.username,"pk":self.post.pk})
def __str__(self):
return self.text
forms.py of posts app-
from django import forms
from posts import models
class PostForm(forms.ModelForm):
class Meta:
# fields = ("message", "group")
fields = ('question','description','picture')
model = models.Post
class CommentForm(forms.ModelForm):
class Meta:
# fields = ("message", "group")
fields = ('comment',)
model = models.Comment
