Hi Daniel,
Thank you for your anwer. I tested the option for using level: INFO for the
django.template -logger. Your solution will suppress the
Exception while resolving variable 'is_popup' in template 'admin/index.html'
. ...
being caught. However, I do not understand why should I just *suppress
*Exceptions/KeyErrors
in the templates? I did not understand *why* this exception is raised. If
there is no such variable as 'is_popup', shoudn't I just provide one?
Forgive me for asking if the answer is too trivial.
I opened the 'admin/index.html' which extends 'base_site.html', which
extends 'base.html', which has following lines (from the beginning of the
file):
{% load i18n static %}<!DOCTYPE html>
{% get_current_language as LANGUAGE_CODE %}{% get_current_language_bidi as
LANGUAGE_BIDI %}
<html lang="{{ LANGUAGE_CODE|default:"en-us" }}" {% if LANGUAGE_BIDI
%}dir="rtl"{% endif %}>
<head>
<title>{% block title %}{% endblock %}</title>
<link rel="stylesheet" type="text/css" href="{% block stylesheet %}{%
static "admin/css/base.css" %}{% endblock %}" />
{% block extrastyle %}{% endblock %}
{% if LANGUAGE_BIDI %}<link rel="stylesheet" type="text/css" href="{% block
stylesheet_rtl %}{% static "admin/css/rtl.css" %}{% endblock %}" />{% endif
%}
{% block extrahead %}{% endblock %}
{% block blockbots %}<meta name="robots" content="NONE,NOARCHIVE" />{%
endblock %}
</head>
{% load i18n %}
<body class="{% if is_popup %}popup {% endif %}{% block bodyclass %}{%
endblock %}"
data-admin-utc-offset="{% now "Z" %}">
<!-- Container -->
<div id="container">
{% if not is_popup %}
<!-- Header -->
<div id="header">
<div id="branding">
{% block branding %}{% endblock %}
</div>
as we can see, there are exactly two lines in the (index.html) base.html
having 'is_popup'.
Could you, or someone else please enlighten me a bit more. Is it possible
to get rid of this Exception/KeyError, other than filtering out it from the
log?
