无需在数据库中存储数据的Django项目

Question

I wrote a script to collect some informations about products offerred by few eShops. This script runs once an hour and collects data to csv file. File is overwritten everytime so it contains currently offered products only. Csv file contains fields - shop name, price, vendor, description, size, picture URL, product page URL and looks like this (just two lines of about 1500 lines)

sklep-presto.pl, 149.90, real, Deck Davis Northern Light 8,38 Real, 8.38, https://www.sklep-presto.pl/pol_il_Deck-Davis-Northern-Light-8-38-Real-59111.jpg, https://www.sklep-presto.pl/product-pol-59111-Deck-Davis-Northern-Light-8-38-Real.html
sklep-presto.pl, 169.90, real, Deck Embossed Elite Ferguson 8,5 Real, 8.5, https://www.sklep-presto.pl/pol_il_Deck-Embossed-Elite-Ferguson-8-5-Real-56151.jpg, https://www.sklep-presto.pl/product-pol-56151-Deck-Embossed-Elite-Ferguson-8-5-Real.html

This script is also generating dictionary csv files - price, vendor, size. These files contain unique values from particular field form main csv file. For example vendor dictionary loks like this

almost,blind,chocolate,deathwish,foundation,goodwood,machine,real,zero
3,3,4,2,3,2,2,9,7

It contains vendor names and occurence count (in main csv).

I would like to make a web page using django but I have never been using django.

I would like to make a web page that will present 5 choice lists and search button on top. Choice lists will be vendor, from price, to price, from size, to size. I would like possible choices to be imported (from csv files) to these choise lists on web page every time the page is loaded.

I don't need to store anything in database because I want to use only current values that are stored in my csv files. Do I have to make djagno model and store data in database?

After search button is pressed I would like chosen values to be passed to my another script that will search the main csv against sarch criteria. Of course this script has to be started after search button is pressed. This script returns may return saerch results line by line or as a list of lists.

I would like the search results to be displayed as tiles on web page. Every tile shoud present as picture and same text values below (name, price, etc.). Tiles should be aligned in columns and rows (20 products per web page).

I don't need to store search results in database because I want to use only current values that are passed from my search engine. Do I have to make djagno model and store data in database?

Can you point me similar porject that I can review to realize how I should do this?

No.

You want a basic Django setup with one view, template and form. Django tutorial project should be a good place to start.

From the documentation:

https://docs.djangoproject.com/en/1.10/topics/db/models/#abstract-base-classes

If you don't want your model to create database tables you put abstract=True in the Meta class

from django.db import models

class CommonInfo(models.Model):
    name = models.CharField(max_length=100)
    age = models.PositiveIntegerField()

    class Meta:
        abstract = True
