Django Class Based Views not rendering variables in Template - django

Question

I'm pretty new to Django and already have read a lot about class-based views before coming here. I'm trying to build a one page website, with dynamic blocks that can be written from the Django admin. My problem is that I cannot manage to render variables from my database in my template. Here's what I wrote:
models.py
from django.db import models
from tinymce.models import HTMLField
class MyResume(models.Model):
subline = models.CharField(max_length=200)
content = HTMLField()
class Meta:
verbose_name = "My Resume"
verbose_name_plural = "My Resume"
def __str__(self):
return "My Resume"
class AboutMe(models.Model):
subline = models.CharField(max_length=200)
content = HTMLField()
cover_img = models.ImageField(upload_to="about_me")
class Meta:
verbose_name = "About me"
verbose_name_plural = "About me"
def __str__(self):
return "About me"
class Experience(models.Model):
subline = models.CharField(max_length=200)
pres_content = models.TextField()
exp_content = HTMLField()
date_exp = models.IntegerField()
class Meta:
verbose_name = "Experience"
verbose_name_plural = "Experiences"
def __str__(self):
return "Experience"
class ProjectPost(models.Model):
title = models.CharField(max_length=200)
technology = models.CharField(max_length=100)
subline = models.CharField(max_length=200)
content = HTMLField()
project_post_cover = models.ImageField(upload_to="projectpost_cover")
class Meta:
verbose_name = "Project Post"
verbose_name_plural = "Project Posts"
def __str__(self):
return self.title
class BlogPost(models.Model):
title = models.CharField(max_length=200)
overview = models.TextField()
timestamp = models.DateTimeField(auto_now_add=True)
content = HTMLField()
blogpost_thumbnail = models.ImageField(upload_to="blogpost_thumbnail")
class Meta:
verbose_name = "Blog Post"
verbose_name_plural = "Blog Posts"
def __str__(self):
return self.title
class Contact(models.Model):
subline = models.CharField(max_length=200)
presentation_content = HTMLField()
def __str__(self):
return "Contact section text"
views.py
from django.shortcuts import render
from django.views.generic.base import TemplateView
from .models import *
class IndexTemplateView(TemplateView):
template_name = 'index.html'
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs) # first, call super get context data
context['myresume'] = MyResume.objects.all()
context['aboutme'] = AboutMe.objects.all()
context['experience'] = Experience.objects.all()
context['projectpost'] = ProjectPost.objects.all()
context['blogpost'] = BlogPost.objects.all()
context['contact'] = Contact.objects.all()
return context
core.urls.py:
from django.urls import path
from .views import IndexTemplateView
urlpatterns = [
path('', IndexTemplateView.as_view()),
]
appname.urls.py:
from django.contrib import admin
from django.urls import include, path
from django.conf.urls import url
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('admin/', admin.site.urls),
url(r'^tinymce/', include('tinymce.urls')),
path('', include('core.urls')),
]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
and a snippet from my index.html template:
{% extends 'base.html' %}
{% load static %}
{% block content %}
(...)
<!-- ==================== ABOUT ==================== -->
<section id="about" class="section">
<h2 class="title">ABOUT</h2>
<div class="section-des">
{{ aboutme.subline }}
</div>
<div class="content-670">
<p>
{{ aboutme.content }}
</p>
</div>
<img class="about-img block-right" data-jarallax-element="0 -40" src="{{ aboutme.cover_img.url }}" alt="">
(...)
{% endblock content %}

Answer 1

All of the variables you've added to your template context are querysets, not objects. But you're trying to read them as individual objects in your template, which is why it doesn't work. You have two options:
Iterate over each queryset in your template:
{% for item in aboutme %}
<h2 class="title">ABOUT</h2>
{{ item.subline }}
{{ item.content }}
{% endfor %}
If you only want to display one of each model, then you need to fix your context method to only return one object, e.g.,
context['aboutme'] = AboutMe.objects.first()
Where here you're just returning the first AboutMe object in the database. If you do this, then your existing template logic will work. How you determine which object to return depends on what your data looks like.

Answer 2

{% for obj in myresume %}
<p>{{ obj.subline }}</p>
{% endfor %}
{% for obj in aboutme %}
<p>{{ obj.subline }}</p>
{% endfor %}
you can call your objects in this way in your templates. Also modify str function in models to get the dynamic content.
class MyResume(models.Model):
subline = models.CharField(max_length=200)
content = HTMLField()
class Meta:
verbose_name = "My Resume"
verbose_name_plural = "My Resume"
def __str__(self):
return self.sublime
