from supabase import create_client
from abc import ABC, abstractmethod
from bisslog import Division, bisslog_db
from bisslog_supabase import BasicSupabaseHelper, bisslog_exc_mapper_supabase


class MarketingDivision(Division, ABC):

    @abstractmethod
    def find_sales_per_client(self, email: str):
        raise NotImplementedError("find_sales_per_client must be implemented")


class MarketingSupabaseDivision(MarketingDivision, BasicSupabaseHelper):

    @bisslog_exc_mapper_supabase
    def find_sales_per_client(self, email: str):
        return self.find_one("sales", {"email": email})


supabase_url = os.environ["SUPABASE_URL"]

## Components

### BasicSupabaseHelper

`BasicSupabaseHelper` is a helper class for interacting with Supabase tables via the official SDK.  
It provides convenient methods for performing insert, query, and count operations while maintaining traceability through `TransactionTraceable`.

#### **Initialization**
~~~python
BasicSupabaseHelper(client: SupabaseClient)
~~~

Initializes the helper with a `SupabaseClient` instance.

#### **Methods**

- `insert_one`
~~~python
insert_one(table: str, data: dict) -> Optional[dict]
~~~
Inserts a record into the specified table and returns the inserted data or None.

- `find_one`
~~~python
find_one(table: str, filters: dict) -> Optional[dict]
~~~
Fetches a single row matching the filters or returns None.

- `get_length`
~~~python
get_length(table: str, filters: Optional[dict] = None) -> int
~~~
Returns the number of matching rows in the given table.

### bisslog_exc_mapper_supabase
