if data does not exist 'get_object_or_404' will throw 404 error, As per your request You are trying to retrieve data with primary key 1, but data is not available
That’s why you get this error. so please check you table or try with other pk value
def change_quan(request):
qty = request.GET["quantity"]
cid = request.GET["cid"]
print(request.GET)
cart_obj = get_object_or_404(cart,id=cid) # please check this cid value
cart_obj.quantity = qty
cart_obj.save()
return HttpResponse(1)

get_object_or_404 is not the correct choice here. Since object with id=cid was not found in database, 404 error was raised. This is the expected behaviour of get_object_or_404.
Did you mean to use get_or_create object incase the object that is trying to be fetched from database is not found?

How to run python code in html page using django

I am learning web development using django framework. I have little trouble in running python code in an html page. I need to iterate through a list of strings which basically contains the paths of images that I want to show in a carousel. I am getting this error "Invalid block tag on line 83: 'with.i', expected 'endblock'. Did you forget to register or load this tag?" in galleryPage.html file when I try to open that page. These are the few lines of code that I've written so far
/views.py/
def galleryPage(request):
from os import listdir
from os.path import isfile, join
ImageList = []
imagePath = "static/images/gallery/"
for f in listdir(imagePath):
temp = join(imagePath, f)
if isfile(temp):
temp = "../" + temp
ImageList.append(temp)
return render(request, "galleryPage.html", {"imageList": ImageList})

</script>
{% endblock %}

{% with.i = 0 %}
should be
{% with i=0 %}
Why do you have imageList.0 instead of imageList?
Also, I think you may want to consider combining your current "with" and "for" into one "for" loop like in the docs I posted above:
{% for key, image in imageList %}
<div class="mySlides fade">
<div class="numbertext"> {% key %} / {{ imageList.size() }} </div>
<img src="{{ image }}" style="width:100%">
<div class="text">Caption Text</div>
</div>
{% endfor %}
This way you won't need to increment i yourself and you take away some complexity (and some sources of errors).

Dynamically increase the height of the div container

I have two div containers for which I have fixed the height and width. One of the containers holds the body of the blogpost and other holds the list of all the posts created. Since, body of a blogpost or list of posts can be larger than the size of their div container. So, I want to dynamically increase container's size when they exceed its size. How can I achieve it either using css or javascript?

Adding to Marcanuy's answer, you have to remove the bottom:50px given to the #container div.
And by removing position:absolute from unwanted places will make your css neat. If you want to position your div side by side, you can use display:flex for your parent (#container) div.
EDIT: Have also removed the position:absolute property and have added margin:50px to make your div center-aligned. (You can also use padding property)
Refer : JsFiddle
#container {
position:absolute;
top:50px;
left:100px;
right:100px;
}
#content {
padding:0;
width:70%;
min-height:550px;
border:1px solid black;
background-color: #282828 ;
color:white;
}
#rightnav {
width:275px;
min-height:550px;
background-color: #282828 ;
}

Change your height with min-height, this will make your containers have at least the specified height, then they will grow and fit their content needs.
#rightnav {
min-height:550px;
}
#content {
min-height:550px;
}

You can see this Django custom template tags
Django expects template tags to live in a folder called 'templatetags' that is in an app module that is in your installed apps...
/my_project/
/my_app/
__init__.py
/templatetags/
__init__.py
my_tags.py
#my_tags.py
from django import template
register = template.Library()
#register.inclusion_tag('other_template.html')
def say_hello(takes_context=True):
return {'name' : 'John'}
#other_template.html
{% if request.user.is_anonymous %}
{# Our inclusion tag accepts a context, which gives us access to the request #}
<p>Hello, Guest.</p>
{% else %}
<p>Hello, {{ name }}.</p>
{% endif %}
#main_template.html
{% load my_tags %}
<p>Blah, blah, blah {% say_hello %}</p>
The inclusion tag renders another template, like you need, but without having to call a view function. Hope that gets you going.
