Why does Django raise "KeyError"? - python

I am currently trying to implement pagination to my Django web app. However, when I try to use template tags from the library, Django raises a key error. To be specific:
KeyError
KeyError: 'request'
Here is my settings.py:
from django.core.urlresolvers import reverse_lazy
from os.path import dirname, join, exists
import os
# Build paths inside the project like this: join(BASE_DIR, "directory")
BASE_DIR = dirname(dirname(dirname(__file__)))
STATICFILES_DIRS = [join(BASE_DIR, 'static')]
MEDIA_ROOT = join(BASE_DIR, 'media')
MEDIA_URL = "/media/"
# Use Django templates using the new Django 1.8 TEMPLATES settings
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [
join(BASE_DIR, 'templates'),
# insert more TEMPLATE_DIRS here
],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
# Insert your TEMPLATE_CONTEXT_PROCESSORS here or use this
# list if you haven't customized them:

# Ideally move env file should be outside the git repo

The template-tag I am trying to run is:
{% block pagination %}
{% bootstrap_paginate page_obj range=10 show_prev_next="false" show_first_last="true" %}
{% endblock %}
What to do?

The bootstrap_paginate template tag expects your template context to contain the request variable. Make it available by changing your context_processors to:
'context_processors': [
# Insert your TEMPLATE_CONTEXT_PROCESSORS here or use this
# list if you haven't customized them:
'django.contrib.auth.context_processors.auth',
'django.template.context_processors.debug',
'django.template.context_processors.i18n',
'django.template.context_processors.media',
'django.template.context_processors.static',
'django.template.context_processors.tz',
'django.contrib.messages.context_processors.messages',
'django.contrib.auth.context_processors.request', # <-- Here we add the request
],

if you have imported
import django_heroku
Then put this:
django_heroku.settings(local())
in the end of your settings.py file

The way above is the correct way to denote file paths in Python.

Django 1.11 ignoring tempate trans tag

I've set up everything right, and when I launch:
makemessages --locale fr --locale en
it only takes in account the translation string used in the Python files, not in the template files (NB: I have {% load i18n %} in the first line of all the template files). What did I forget?

Django static media not showing picture

after searching for a solution for hours which did not resolve my problem,I am posting this. The image from my media root is not showing up on my html. In chrome's console i get a 404 file not found.Even though the image is there. I am using Python 3 ,Django 1.10 in Pycharm.
This is the model which is where i upload images to:
from django.db import models
class Post(models.Model):
username = "anonymous"
post = models.ImageField(upload_to='anon')
creation_date = models.DateTimeField(auto_now_add=True)
def __str__(self):
return Post.username
views.py:
from django.shortcuts import render,get_object_or_404
from .models import Post
def home(request):
return render(request,"base.html",{})
def post_detail(request,id=None):
instance = get_object_or_404(Post,id=id)
context = {
"post": instance.post,
"instance": instance
}
return render(request,"post_detail.html",context)
post_detail.html(here the image isnt showing):
<body>
<img src = "{{ instance.post.url}}" height="520" width="500"><br>
{{ instance.creation_date }}<br>
{{ instance.username }}<br>

What my directories look like:
It's a common mistake to mix up the static and media settings. In your case what you are actually dealing with is user uploaded MEDIA and not STATICs.
<img src = "{{ instance.post.url}}" height="520" width="500"><br>
The settings that are most relevent are MEDIA_* settings described here
https://docs.djangoproject.com/en/1.10/howto/static-files/
But more importantly, in your dev sever you need to enable the delivery of MEDIA by adding
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
# ... the rest of your URLconf goes here ...
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

If you have only 1 settings.py file, you should change BASE_DIR value with
BASE_DIR = os.path.dirname(os.path.abspath(__file__))
In django 1.8 and later, you should also define a 'templates' folder like 'static'.
Put your html files into "templates" folder and add css/js files like "static/css/bootstrap.css" in your templates(html files).

Also this is my structure
environment/colectr/colectr/django-allauth,
Before take the files from git i got the pypi files for allauth(pip install).
I recommend you to create a project templates directory on the root of your project.
Then you can modify your TEMPLATES variable like this:
from os.path import join, normpath
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [
normpath(join(BASE_DIR, 'templates')),
],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
'django.template.context_processors.request',
],
},
},
]
Then, you will need to create the folder accounts and inside of it create a login.html file to override allauth templates.
Hope it helps,
