3.if 3 , 80th character made place_description,need truncate their.

all fields not mandatory,so whatever field comes display,it should show 80 character.

you use slice pre-django 1.4:

{% if place or other_place or place_description%}     {% place|add:other_place|add:place_description pl %}         {% if pl|length > 80 %}             {{pl|slice:80}}...         {% else  %}             {{pl }}         {% endif %}     {% endwith %} {% endif %} 

if using django 1.4 or greater,

you can use truncatechars

{% if place or other_place or place_description%}     {% place|add:other_place|add:place_description pl %}        {{pl|truncatechars:80}}     {% endwith %} {% endif %}
