Rails Delegated Analyzer

Rails Delegated Analyzer is a Python package designed to help developers understand and apply the Rails Delegated Type pattern. It analyzes text-based descriptions of database relationships or use cases and provides structured explanations for implementing delegated types in Rails applications.

Features

• Analyzes user input about data models or scenarios
• Provides structured explanations for implementing delegated types
• Assists in designing polymorphic-like structures in Rails applications
• Supports custom LLM instances for flexible usage

Installation

pip install rails_delegated_analyzer

Usage

Basic Usage

from rails_delegated_analyzer import rails_delegated_analyzer

user_input = "Describe your data model or scenario here."
response = rails_delegated_analyzer(user_input)
print(response)

Using a Custom LLM Instance

The package uses ChatLLM7 from langchain_llm7 by default. However, you can safely pass your own LLM instance if you want to use another LLM.

Example with OpenAI

from langchain_openai import ChatOpenAI
from rails_delegated_analyzer import rails_delegated_analyzer

llm = ChatOpenAI()
response = rails_delegated_analyzer(user_input, llm=llm)
print(response)

Example with Anthropic

from langchain_anthropic import ChatAnthropic
from rails_delegated_analyzer import rails_delegated_analyzer

llm = ChatAnthropic()
response = rails_delegated_analyzer(user_input, llm=llm)
print(response)

Example with Google

from langchain_google_genai import ChatGoogleGenerativeAI
from rails_delegated_analyzer import rails_delegated_analyzer

llm = ChatGoogleGenerativeAI()
response = rails_delegated_analyzer(user_input, llm=llm)
print(response)

Using a Custom API Key

If you want to use a custom API key for LLM7, you can pass it directly or via an environment variable.

Using Environment Variable

export LLM7_API_KEY="your_api_key"

Passing API Key Directly

from rails_delegated_analyzer import rails_delegated_analyzer

user_input = "Describe your data model or scenario here."
response = rails_delegated_analyzer(user_input, api_key="your_api_key")
print(response)

Rate Limits

The default rate limits for LLM7 free tier are sufficient for most use cases of this package. If you need higher rate limits, you can get a free API key by registering at LLM7.
