offerte_supermercato's Issues

Prezzo al kg

Il prezzo al kg deve essere salvato in due campi distinti anziché una singola stringa:

  1. valore numerico del prezzo unitario unit_price.
  2. unità di misura unit (spesso €/kg o €/l).

Modificare funzioni scraping, invia a telegram, salvataggio nel db e tabella db

Poli via Fermi

Aggiungere script python per web scraping, simile a quanto fatto per eurospin

Lista prodotti da tracciare

Creare lista csv con keyword, marca e prezzo unitario massimo e implementare filtri sui prodotti da tracciare

Minor Issues

  • Fix paths (path to this repo + relative paths),
  • Fix structure (web scraping as function for every supermarket)
  • Add comments

Error fixing

File "/home/nicola/Projects/offerte_supermercato/src/WebScraping.py", line 134, in poli
element['Quantità'] = item.find("span", class_="band-volantino-prodotto-quantita").text
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'text'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "/home/nicola/Projects/offerte_supermercato/src/main.py", line 42, in
message("Errore nello scraping del sito Poli")
TypeError: message() missing 1 required positional argument: 'msg'

Aggiornamento giornaliero

Controllare se lo script funziona nel caso in cui venga lanciato una volta al giorno, senza riproporre le stesse offerte già mostrate.
