From 73b7e8bb9d07a9911551b2fc7e59959cf3998f7d Mon Sep 17 00:00:00 2001 From: "Vasily.onl" Date: Fri, 30 May 2025 18:20:38 +0800 Subject: [PATCH] Refactor database configuration and schema for Crypto Trading Bot Platform - Updated `docker-compose.yml` to remove hardcoded passwords, relying on environment variables for PostgreSQL and Redis configurations. - Modified `env.template` to reflect new password settings and ensure secure handling of sensitive information. - Introduced a new `database/connection.py` file for improved database connection management, including connection pooling and session handling. - Updated `database/models.py` to align with the new schema in `schema_clean.sql`, utilizing JSONB for optimized data storage. - Enhanced `setup.md` documentation to clarify the initialization process and emphasize the importance of the `.env` file for configuration. - Added a new `scripts/init_database.py` script for automated database initialization and verification, ensuring all tables are created as expected. --- config/settings.py | 4 +- database/connection.py | 487 ++++++++++++++++++ database/init/init.sql | 18 +- .../init/{schema.sql => schema_clean.sql} | 63 +-- database/models.py | 19 +- database/schema_clean.sql | 20 + docker-compose.yml | 6 +- docs/setup.md | 80 ++- env.template | 8 +- scripts/dev.py | 4 +- scripts/init_database.py | 179 +++++++ tasks/tasks-crypto-bot-prd.md | 35 +- 12 files changed, 781 insertions(+), 142 deletions(-) create mode 100644 database/connection.py rename database/init/{schema.sql => schema_clean.sql} (82%) create mode 100644 scripts/init_database.py diff --git a/config/settings.py b/config/settings.py index 7e64d59..daecdd9 100644 --- a/config/settings.py +++ b/config/settings.py @@ -21,10 +21,10 @@ class DatabaseSettings(BaseSettings): """Database configuration settings.""" host: str = Field(default="localhost", env="POSTGRES_HOST") -
