flow disappears from hugging face about langflow HOT 6 OPEN

To prevent your flow from disappearing on Hugging Face after a day when using Langflow 1.0 preview, ensure that your flows are being saved to the database. You can use the saveFlow method to save your flow data. Here is a relevant snippet from the code:

const useFlowsManagerStore = create<FlowsManagerStoreType>((set, get) => ({
  saveFlow: (flow: FlowType, silent?: boolean) => {
    set({ saveLoading: true });
    return get().saveFlowDebounce(flow, silent);
  },
  saveFlowDebounce: debounce((flow: FlowType, silent?: boolean) => {
    set({ saveLoading: true });
    return new Promise<void>((resolve, reject) => {
      updateFlowInDatabase(flow)
        .then((updatedFlow) => {
          if (updatedFlow) {
            if (!silent) {
              useAlertStore
                .getState()
                .setSuccessData({ title: "Changes saved successfully" });
            }
            get().setFlows(
              get().flows.map((flow) => {
                if (flow.id === updatedFlow.id) {
                  return updatedFlow;
                }
                return flow;
              })
            );
            resolve();
            set({ saveLoading: false });
          }
        })
        .catch((err) => {
          useAlertStore.getState().setErrorData({
            title: "Error while saving changes",
            list: [(err as AxiosError).message],
          });
          reject(err);
        });
    });
  }, SAVE_DEBOUNCE_TIME),
}));

Additionally, check your database settings in the .env file to ensure they are correctly configured:

LANGFLOW_DATABASE_URL=sqlite:///./langflow.db
LANGFLOW_SAVE_DB_IN_CONFIG_DIR=

Make sure LANGFLOW_DATABASE_URL points to your desired database and LANGFLOW_SAVE_DB_IN_CONFIG_DIR is set according to your preference. This should help prevent your flows from disappearing.

You can find the relevant code and configuration settings in the source files of this repository. Specifically, look for the FlowsManagerStore implementation in the frontend code, which is typically located in a file related to state management (e.g., store.js or flowsManagerStore.ts). For the database settings, check the .env file in the root directory of the project.

If you have cloned the repository locally, you can use a text editor or IDE to search for saveFlow and LANGFLOW_DATABASE_URL to locate these sections quickly. If you need further assistance navigating the repository, please let me know!

To ensure that your flows are being saved to the database in your Hugging Face deployment of Langflow 1.0 preview, you need to check two main components: the FlowsManagerStore implementation and the .env file.

1. FlowsManagerStore Implementation

The FlowsManagerStore implementation is responsible for managing the saving and retrieval of flows. You can find this implementation in the following file:

• File Path: src/frontend/src/stores/flowsManagerStore.ts
• Repository URL: FlowsManagerStore Implementation

2. .env File Configuration

The .env file is used to set environment variables for your application, including database configuration settings. This file is typically located in the root directory of your project. Here is an example of what the .env file might look like:

LANGFLOW_DATABASE_URL=sqlite:///./langflow.db
LANGFLOW_SAVE_DB_IN_CONFIG_DIR=

Ensure that the LANGFLOW_DATABASE_URL is correctly set to point to your database. This setting is crucial for saving your flows to the database.

By ensuring these configurations are correct, you can prevent your flows from disappearing and ensure they are saved persistently in the database.
