From 688503a1ca723c4b4aafc91d18b2f1a40dd8cfd2 Mon Sep 17 00:00:00 2001 From: Eternity <1533512157@qq.com> Date: Mon, 20 Apr 2026 17:43:52 +0800 Subject: [PATCH] refactor(memory): integrate unified memory service into agent controller - Replace direct memory agent service calls with unified MemoryService in read endpoint - Update query preprocessor to use new prompt format and return structured queries - Enhance MemorySearchResult model with filtering, merging, and ID tracking capabilities - Add intermediate outputs display for problem split, perceptual retrieval, and search results - Fix parameter alignment and remove unused history parameter in memory agent service --- .../controllers/memory_agent_controller.py | 105 +++++-- api/app/core/memory/enums.py | 2 + api/app/core/memory/memory_service.py | 16 +- api/app/core/memory/models/service_models.py | 24 ++ api/app/core/memory/pipelines/memory_read.py | 59 +++- .../core/memory/prompt/problem_split.jinja2 | 269 +++++------------- .../memory/read_services/content_search.py | 65 ++++- .../read_services/query_preprocessor.py | 18 +- .../memory/read_services/result_builder.py | 4 + .../access_history_manager.py | 2 +- api/app/core/workflow/nodes/memory/node.py | 33 ++- api/app/services/draft_run_service.py | 70 ++--- api/app/services/memory_agent_service.py | 8 +- api/app/services/memory_config_service.py | 16 +- 14 files changed, 372 insertions(+), 319 deletions(-) diff --git a/api/app/controllers/memory_agent_controller.py b/api/app/controllers/memory_agent_controller.py index aa4d48e3..cba17f42 100644 --- a/api/app/controllers/memory_agent_controller.py +++ b/api/app/controllers/memory_agent_controller.py @@ -12,6 +12,8 @@ from app.core.language_utils import get_language_from_header from app.core.logging_config import get_api_logger from app.core.memory.agent.utils.redis_tool import store from app.core.memory.agent.utils.session_tools import SessionService +from app.core.memory.enums import SearchStrategy, Neo4jNodeType +from app.core.memory.memory_service import MemoryService from app.core.rag.llm.cv_model import QWenCV from app.core.response_utils import fail, success from app.db import get_db @@ -23,6 +25,7 @@ from app.schemas.memory_agent_schema import UserInput, Write_UserInput from app.schemas.response_schema import ApiResponse from app.services import task_service, workspace_service from app.services.memory_agent_service import MemoryAgentService +from app.services.memory_agent_service import get_end_user_connected_config as get_config from app.services.model_service import ModelConfigService load_dotenv() @@ -300,33 +303,90 @@ async def read_server( api_logger.info( f"Read service: group={user_input.end_user_id}, storage_type={storage_type}, user_rag_memory_id={user_rag_memory_id}, workspace_id={workspace_id}") try: -
