Re: How to intergrate openpyxl with django and using the excel sheet as the database to query data

In top of views files (views.py) you must put:

import openpyxl

from openpyxl import Workbook

from openpyxl.styles import Alignment,Border,Font,PatternFill,Side

from openpyxl.styles import colors

from openpyxl.styles import Font, Color,Fill

from openpyxl.styles.borders import BORDER_THIN

from openpyxl.drawing.image import Image as XLIMG

...and the view which prepare the excel out, you should review this example:

# CARTOLA DE RECAUDACION en excel

@login_required(login_url='login_ini')

def acsv(request):

nom_arch = nombrearch() # Se forma string para nombre de archivo excel

string_nombre = 'pac'+nom_arch

query = Pauta_aux.objects.all().order_by('rut') # viene filtrada x rango de fecha

reg_x = 0

if query:

for fech_x in query:

reg_x = reg_x + 1

else:

# estas dos instrucciones van juntas siempre

messages.error(request, "No existen movimientos que mostrar !!")

return redirect("info")

mes_x = fechapautas.strftime('%m')

ano_x = fechapautas.strftime('%Y')

fecha_ini = str(ano_x)+"-"+str(mes_x).zfill(2)+"-01 00:00:00"

#total dias del mes

totdias = calendar.monthrange(int(ano_x),int(mes_x))[1] 

fecha_fin = str(ano_x)+"-"+str(mes_x).zfill(2)+"-"+str(totdias)+" 00:00:00"

Hello Everyone,

I have a python file which I run on the terminal and give me the result that I want. I want to to do the same via a web app whereby instead of interacting with the terminal, I can do that via a browser through a form. I have decided to choose django as the server. Below is the file that I need to integrate to django. It works well in the terminal. I also have the excel file.

Now my concern was how can I integrate it with django such that fields like link_name can be filed through a form and when I click a button should give the required results. Thank you fo your time.

def find_fault(request):

wb = xl.load_workbook("Find Fault App Documentation.xlsx")

distance1 = distance * 1000 + sheet.cell(i, 2).value

for value in range(2, sheet.max_row + 1):

cell = sheet.cell(value, 2)

cell1 = sheet.cell(value, 1)

cell2 = sheet.cell(value, 3)

if cell.value in range(int(distance1) - error, int(distance1) + error):

if nature == "kink":

print()

print("Kink at {cell1.value}")

print("Pairs at this point:")

print(cell2.value)

print()

print("Break at {cell1.value}")

print("Pairs at this point:")

print(cell2.value)

else:

print()

cell1 = sheet.cell(value, 2)

cell2 = sheet.cell(value + 1, 2)

cell3 = sheet.cell(value, 4)

cell4 = sheet.cell(value, 1)
