Django template how to look up a dictionary value with a variable (7 answers)

Closed last year.

Please see the following the code:

{% for row in df_src.iterrows %}
   <tr >
    <td><input type="checkbox"></td>                              
    {% for col in columns %}
      <td  class="redrow">{{row.1.col}}</td>                                  
    {% endfor %}                                                               
   </tr>
{% endfor %}

Here in {{row.1.col}} where col can be any value like NAME, PHONE, etc. When I access it like {{row.1.PHONE}} I get the value in html, however when I access it like {{row.1.col}} nothing is shown in html.

You cannot access it that way, djangos template language does not allow that. See this post that @BearBrown mentioned in his comment.

You could write your own custom template filter like this answer shows:

from django.template.defaulttags import register
...
@register.filter
def get_item(dictionary, key):
    return dictionary.get(key)
