Your goal is to produce consistent, reusable code for pages that allow users to view, edit, add, and remove entries (e.g., Grades, Silos, Compounders) within a multi-page Streamlit app. # Communication & Style Preferences - Use clear, descriptive variable names. - Follow the specific layout and widget patterns requested by the user (e.g., wide layout, expanders, specific column arrangements). - Ensure all code is syntactically correct Python compatible with Streamlit. - Maintain consistency across similar pages (Grade Config, Silo Config, Compounder Config). # Operational Rules & Constraints - **Data Loading**: Always load data using `st.session_state['DataManager'].load__dict()`. Assume `DataManager` exists in `st.session_state`. - **Data Saving**: Always save data using `st.session_state['DataManager'].save__dict(data_dict)`. - **Page Layout**: Always set `st.set_page_config(layout="wide")` at the start of the page function. - **Sidebar**: Always include a sidebar description at the top of the page function using `st.sidebar.title()` and `st.sidebar.info()` to explain how to use the page. - **Top Control Bar**: Always include three buttons in a row at the top of the page: "Expand All s", "Collapse All s", and "Save Configurations". - The "Expand All" button iterates through `st.session_state.keys()` and sets any key starting with 'expander_' to `True`. - The "Collapse All" button sets these keys to `False`. - The "Save Configurations" button calls the DataManager save method for the specific entity. - **Expanders**: Display each entry in an `st.expander`. The expander title should follow the format " " (e.g., "Silo 1", "Grade GE4760"). The expander state should be controlled by a session state key `f'expander_{id}'`. - **Forms for Management**: Include an expander at the bottom labeled "Manage s" containing two forms: one to add a new entry and one to remove an existing entry. - **Add Form**: Inputs should match the data structure. Use `st.form_submit_button` to trigger the add action. On submission, update the dictionary, save via DataManager, and call `st.experimental_rerun()`. - **Remove Form**: Use a selectbox to pick an ID to remove. On submission, delete the entry, save via DataManager, and call `st.experimental_rerun()`. - **Widget Keys**: Ensure all widgets have unique keys, typically constructed as `f'_{id}'` to avoid `DuplicateWidgetID` errors. - **Session State Initialization**: Initialize session state keys for expanders if they do not exist using `st.session_state.setdefault()`. # Anti-Patterns - Do not modify `st.session_state` directly after a widget with the same key is instantiated (e.g., do not assign `st.session_state.new_id = ...` after `st.text_input(..., key="new_id")`). Use the widget's return value or session state binding instead. - Do not iterate over a dictionary and modify it (delete keys) simultaneously; collect keys to remove and process them after the loop. - Do not hardcode specific entity names (like 'GE4760', 'Line 8') into the reusable logic; treat them as runtime data. - Do not use `on_change` callbacks for simple updates; rely on the "Save Configurations" button or form submission to persist changes. # Interaction Workflow 1. Set page layout to wide. 2. Render Sidebar Help. 3. Render Top Control Bar (Expand All, Collapse All, Save). 4. Load data from DataManager. 5. Iterate through data to render expanders for each item. - Inside each expander, render input widgets (text_input, number_input, selectbox, multiselect) with unique keys. - Bind widget values to session state or local variables to be saved later. 6. Render "Manage s" expander at the bottom. - Inside, render "Add New " form. - Inside, render "Remove " form. 7. Handle form submissions to update the in-memory dictionary, save to DataManager, and rerun. ## Triggers - create a streamlit page for configuration - generate a config page for grades silos or compounders - make a streamlit page with expanders and forms - create a sidebar help section for streamlit - implement expand all and collapse all buttons --- Source attribution: ECNU-ICALK Original project: https://github.com/ECNU-ICALK/AutoSkill License: MIT License information: https://opensource.org/license/mit Original upstream instructions; downloaded from Mega AI Hub. ## Upstream license notice MIT License Copyright (c) 2026 Gabriel Moreira Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
