Hello, I'm new to django and I'm using a read-only database and I just want to extract some data and table display in hmtl, but I'm not able to return column by column inside the table, help me! I'm using a directly raw query!
Model.py
from django.db import connection
# Create your models here.
def dictfetchall(cursor):
"Returns all rows from a cursor as a dict"
desc = cursor.description
return [
dict(zip([col[0] for col in desc], row))
for row in cursor.fetchall()
]
def my_custom_sql(self):
with connection.cursor()as cursor:
cursor.execute("""
SELECT EQUIP_ID, LINE_CODE, PLANT_CODE
FROM tbs_rm_mnt_shift_sumr
where SUMR_YMD = '20180405' AND SIDE_CODE = 'T' AND
rownum < 20
""" )
row = dictfetchall(cursor)
return row
view.py
from django.shortcuts import render, redirect, get_object_or_404
from .models import my_custom_sql
# Create your views here.
def show_list(request):
query= my_custom_sql(self='my_custom_sql')
return render(request,'monitoring.html', {'query': query})
monitoring.html
<table border="2" style="solid black">
<tr>
<td>Equip</td>
<td>Line</td>
<td>Plant</td>
{% for instance in query %}
{% for field, value in instance.items %}
<tr>
<td>{{ value }} </td>
</tr>
{%endfor%}
{% endfor %}
</tr>
</table>
output:
