Function to check frequency of customer ordering patterns

Function to check frequency of customer ordering patterns

Hi,

I'm no coder, so I thought I could make use of Chat GPT to generate some Deluge script to create a function that would check order frequency of our customers so that I could send an email if they go beyond their usual order pattern.

Chat GPT and Claude seemed super confident they could do the job, but failed. I keep getting errors.

Here's sample code:

string calculateOrderFrequency(string orderID)
{
    // Get the Contact associated with this order
    contactInfo = zoho.crm.getRelatedRecords("Contacts", "Sales_Orders", orderID);
    
    // If no contact is found, exit the function
    if(contactInfo.isEmpty())
    {
        return "No contact found for this order";
    }
    
    // Get the contact ID from the first related contact
    contactId = contactInfo.get(0).get("id");
    
    // Retrieve all previous orders for this contact
    previous_orders = zoho.crm.getRelatedRecords("Sales_Orders", "Contacts", contactId);
    
    // We need at least 2 orders to calculate frequency
    if(previous_orders.size() >= 2)
    {
        // Create a list to store order dates
        order_dates = List();
        
        // Add all order dates to our list
        for each rec in previous_orders
        {
            orderDate = rec.get("Order_Date");
            if(orderDate != null)
            {
                order_dates.add(orderDate);
            }
        }
        
        // Sort dates from oldest to newest
        order_dates.sort();
        
        // Calculate time between orders using a different approach
        total_days = 0;
        intervals = 0;
        
        // Calculate date differences without using a standard loop
        latest_index = order_dates.size() - 1;
        
        // Process manually if we have at least 2 dates
        if(latest_index >= 1)
        {
            // Manually calculate first interval
            days_diff_1 = dateDiff(order_dates.get(1), order_dates.get(0), "days");
            total_days = total_days + days_diff_1;
            intervals = intervals + 1;
            
            // Manually calculate second interval if we have enough dates
            if(latest_index >= 2)
            {
                days_diff_2 = dateDiff(order_dates.get(2), order_dates.get(1), "days");
                total_days = total_days + days_diff_2;
                intervals = intervals + 1;
                
                // Manually calculate third interval if we have enough dates
                if(latest_index >= 3)
                {
                    days_diff_3 = dateDiff(order_dates.get(3), order_dates.get(2), "days");
                    total_days = total_days + days_diff_3;
                    intervals = intervals + 1;
                    
                    // Manually calculate fourth interval if we have enough dates
                    if(latest_index >= 4)
                    {
                        days_diff_4 = dateDiff(order_dates.get(4), order_dates.get(3), "days");
                        total_days = total_days + days_diff_4;
                        intervals = intervals + 1;
                        
                        // Manually calculate fifth interval if we have enough dates
                        if(latest_index >= 5)
                        {
                            days_diff_5 = dateDiff(order_dates.get(5), order_dates.get(4), "days");
                            total_days = total_days + days_diff_5;
                            intervals = intervals + 1;
                        }
                    }
                }
            }
        }
        
        // Calculate average frequency (if we have valid intervals)
        if(intervals > 0)
        {
            avg_frequency = total_days / intervals;
            
            // Round to nearest whole number
            avg_frequency = round(avg_frequency);
            
            // Create map of fields to update
            update_map = Map();
            update_map.put("Average_Order_Frequency", avg_frequency);
            update_map.put("Last_Order_Date", order_dates.get(order_dates.size() - 1));
            update_map.put("Email_Sent_Flag", false);
            
            // Update the contact record
            update_response = zoho.crm.updateRecord("Contacts", contactId, update_map);
            return "Updated contact with average order frequency: " + avg_frequency + " days";
        }
        else
        {
            return "Could not calculate intervals between orders";
        }
    }
    else
    {
        // If this is their first order, just update the last order date
        if(previous_orders.size() == 1)
        {
            update_map = Map();
            update_map.put("Last_Order_Date", previous_orders.get(0).get("Order_Date"));
            update_map.put("Email_Sent_Flag", false);
            zoho.crm.updateRecord("Contacts", contactId, update_map);
            return "First order - updated last order date only";
        }
        else
        {
            return "No orders found for this contact";
        }
    }
}

Not sure if that is safe, but it's the best I can think of to be semi scalable and obviously better than sending emails. I am open to another idea, just thought this would be a great feature.  Thanks,
