This will return a template-friendly list of dictionaries when using custom SQL. The dictionary can be accessed just as a normal model/queryset.

Example of use (in view):

qkeys = ['artist','album']
query = """
    SELECT "artist","album" FROM "music"
    """ 
new_list = csql(request,query,qkeys)

(in template)

{% for row in new_list %}
    {{ row.artist }} {{ row.album }}
{% endfor %}

# custom query function:
def csql(self,query,qkeys):
    from django.db import connection
    cursor = connection.cursor()
    cursor.execute(query)
    rows = cursor.fetchall()
    
    # build dict for template:
    fdicts = []
    for row in rows:
        i = 0
        cur_row = {}
        for key in qkeys:
            cur_row[key] = row[i]
            i = i+1
        fdicts.append(cur_row)
    return fdicts
