from pathlib import Path

from agno.agent import Agent
from agno.knowledge.docx import DocxKnowledgeBase
from agno.utils.media import (
    SampleDataFileExtension,
    download_knowledge_filters_sample_data,

# 下载所有样本简历并获取其路径
downloaded_cv_paths = download_knowledge_filters_sample_data(
    num_files=5, file_extension=SampleDataFileExtension.DOCX
)

# 初始化 LanceDB
# 默认情况下，它将数据存储在 /tmp/lancedb
vector_db = LanceDb(
    table_name="recipes",
    uri="tmp/lancedb",  # 您可以将此路径更改为存储其他位置的数据
)

# 步骤 1：使用文档和元数据初始化知识库
# ------------------------------------------------------------------------------
# 在初始化知识库时，我们可以附加将用于过滤的元数据
# 此元数据可以包括用户 ID、文档类型、日期或任何其他属性

# 将所有文档加载到向量数据库中
knowledge_base.load(recreate=True)

# 步骤 2：使用具有从查询中自动提取的过滤器的 Agent 查询知识库
# -----------------------------------------------------------------------------------

# 启用代理过滤
agent = Agent(
    knowledge=knowledge_base,
    search_knowledge=True,
    enable_agentic_knowledge_filters=True,
)

# 查询 Jordan Mitchell 的经验和技能，并在查询中包含过滤器，以便 Agent 可以自动获取它们
agent.print_response(
    "Tell me about Jordan Mitchell's experience and skills with jordan_mitchell as user id and document type cv",
    markdown=True,
)
