django.template.base.TemplateSyntaxError: 'block' tag with name 'bottom_js' appears more than once

Question

I have this error : django.template.base.TemplateSyntaxError: 'block' tag with name 'bottom_js' appears more than once

But I have no clue which template is at fault, how do I find this out ?

django.template.base.TemplateSyntaxError: 'block' tag with name 'bottom_js' appears more than once

EDIT: In a template I found this :

{% render_block "bottom_js" %}
{% block bottom_js %}
    <script>
     stufff
    </script>
{% endblock %}

Does it make a duplicate of the bottom_js block ?

Do you have Debug=True in your settings.py? You should get a stacktrace. — Henrik Andersson
I have the stacktrace but it does not mention the template name — maazza
It should post where it originates from. Could you post it, please? — Henrik Andersson
Yes, that produces two blocks. It's from Sekizai. If you want to add to that block use the tags {% addtoblock "bottom_js" %} {% endaddtoblock %}. — Henrik Andersson
ok , but it seems i need to check all the templates for it , damn — maazza

Ok fixed using a search in Pycharm and spotting 2 usages in the same File. I hope there is way to find it out without PyCharm tough.

grep equivalent:

 grep -r -i "bottom_js" ./
