Export/Import Overviews using the rails console

Changed the code to make it work better:

import json
import requests
from requests.exceptions import HTTPError

# Function to load JSON data from a file
def load_json_from_file(file_path):
    try:
        with open(file_path, 'r') as file:
            json_data = json.load(file)
        return json_data
    except FileNotFoundError:
        print(f"Error: The file '{file_path}' was not found.")
        return None
    except json.JSONDecodeError:
        print(f"Error: The file '{file_path}' does not contain valid JSON.")
        return None

# Function to delete all overviews from the API endpoint
def delete_all_overviews(api_url, api_token):
    headers = {
        'Content-Type': 'application/json',
        'Authorization': f'Token token={api_token}'
    }
    
    try:
        response = requests.get(api_url, headers=headers, verify=False)
        response.raise_for_status()  # Raise an HTTPError if the HTTP request returned an unsuccessful status code
        overviews = response.json()
        
        for overview in overviews:
            delete_url = f"{api_url}/{overview['id']}"
            delete_response = requests.delete(delete_url, headers=headers, verify=False)
            delete_response.raise_for_status()  # Raise an HTTPError if the delete request returned an unsuccessful status code
            print(f"Overview with id {overview['id']} deleted successfully.")
            
    except HTTPError as http_err:
        print(f"HTTP error occurred while deleting overviews: {http_err}")
        if response.content:
            print(f"Response content: {response.content.decode()}")  # Print response content for more details
    except Exception as err:
        print(f"An error occurred while deleting overviews: {err}")

# Function to import a JSON object to the API endpoint
def import_json_to_api(json_data, api_url, api_token):
    headers = {
        'Content-Type': 'application/json',
        'Authorization': f'Token token={api_token}'
    }
    
    # If json_data is a list, iterate over each item and send it separately
    if isinstance(json_data, list):
        for item in json_data:
            try:
                response = requests.post(api_url, headers=headers, data=json.dumps(item), verify=False)
                response.raise_for_status()  # Raise an HTTPError if the HTTP request returned an unsuccessful status code
                print(f"JSON data imported successfully: {response.status_code}")
            except HTTPError as http_err:
                print(f"HTTP error occurred: {http_err}")  # HTTP error
                if response.content:
                    print(f"Response content: {response.content.decode()}")  # Print response content for more details
            except Exception as err:
                print(f"An error occurred: {err}")  # Other errors
    else:
        try:
            response = requests.post(api_url, headers=headers, data=json.dumps(json_data), verify=False)
            response.raise_for_status()  # Raise an HTTPError if the HTTP request returned an unsuccessful status code
            print(f"JSON data imported successfully: {response.status_code}")
        except HTTPError as http_err:
            print(f"HTTP error occurred: {http_err}")  # HTTP error
            if response.content:
                print(f"Response content: {response.content.decode()}")  # Print response content for more details
        except Exception as err:
            print(f"An error occurred: {err}")  # Other errors

# Load JSON data from file
def import_overview(json_filename, api_url, api_token):
    json_data = load_json_from_file(json_filename)

    if json_data:
        delete_all_overviews(api_url, api_token)  # Delete all existing overviews before importing
        import_json_to_api(json_data, api_url, api_token)

# Example usage
domain_url = 'https://example.com'  # Replace with your actual domain URL
api_endpoint = '/api/v1/overviews/'
api_url = f'{domain_url}{api_endpoint}'
api_token = 'your_api_token'  # Replace with your actual API token

# Load JSON data from file and import it
json_file_path = 'path_to_your_json_file.json'  # Replace with your actual JSON file path
import_overview(json_file_path, api_url, api_token)

This way, we first delete all existing overviews and then import all the overviews again

My suggestion is to always cleanly import all overviews
