Fix PlayerUsageUsage validation for string inputs and hireDate null value handling for coaches

[AjJ132]

Fixes Issue #13 and #15

Problem

The PlayerUsageUsage class was failing to validate inputs when the API returned numeric values as strings.

Solution

Added a validator to convert string inputs to floats, allowing the model to handle both string and numeric inputs. This makes the PlayerUsageUsage class more robust and able to handle different input formats without breaking.

Changes

• Added a @validator decorator to convert string inputs to floats

Testing

Tested with test files in ./test folder

Backwards Compatibility

This change maintains backwards compatibility as it will still work with numeric inputs.

Fix hireDate parsing in Coach model

Changes

Modified the hire_date field in the Coach model to be an optional string.

File changed: models/coach.py

This PR addresses the issue with parsing the hireDate field in the Coach model. It changes the field to an optional string to avoid validation errors with null or improperly formatted dates.

from typing import Optional
from pydantic import BaseModel, Field

class Coach(BaseModel):
    first_name: str = Field(..., alias="firstName")
    last_name: str = Field(..., alias="lastName")
    hire_date: Optional[str] = Field(default=None, alias="hireDate")
    # ... other fields remain unchanged ...

    class Config:
        allow_population_by_field_name = True

# ... rest of the file remains unchanged ...

Testing

Tested with test files in ./test folder

I found another issue with parsing the coaches hireDate. Some coaches have a null hireDate. Example below

[
  {
    "firstName": "Steve",
    "lastName": "Addazio",
    "hireDate": null,
    "seasons": [
      {
        "school": "Temple",
        "year": 2011,
        "games": 13,
        "wins": 9,
        "losses": 4,
        "ties": 0,
        "preseasonRank": null,
        "postseasonRank": null,
        "srs": 5.4,
        "spOverall": 4.6,
        "spOffense": 26.4,
        "spDefense": 22.5
      },
      ..................
    ]
  }
]
