How to properly load in game information for positional constraints?

[McCampy]

Hi there again, I am trying to use the restrict positions for opposing team constraint but I can't seem to load in the game variable correctly. I'm not exactly sure how to give each player the home_team attribute because it doesn't seem like you can add is a kwarg. Any insight on fixing this would be great. Cheers.

CSV: FD.csv

Code:

import pandas as pd 
from pydfs_lineup_optimizer import get_optimizer, Site, Sport, Player

dffd = pd.read_csv(r'E:\DFS\CSV_Downloads\08-08-21\FD.csv')
dffd[['home_team','away_team']] = dffd['Game'].str.split('@', expand=True)

o = get_optimizer(Site.FANDUEL, Sport.BASEBALL)

def row_to_player(row):
    """Converts dataframe row to Player object

    Args:
         row (namedtuple): dataframe row

    Returns:
        Player
    """
    valid_kwargs = {

        'min_deviation', 'max_deviation', 'is_confirmed_starter', 
        'fppg_floor', 'fppg_ceil'
    }

    kwargs = {}
    for name, value in row._asdict().items():
        if name in valid_kwargs:
            kwargs[name] = value    

    return Player (
        player_id=getattr(row, 'id') if hasattr(row, 'id') else row.first_name + ' ' + row.last_name,

You got this error because game_info is string in your code. It should be GameInfo object

Ah makes sense, thank you.
