How can I trigger a WhatsApp Notification? about frappe_whatsapp HOT 5 CLOSED

@ahassoun
On click of button you can call an api with below snippet
In you python code you can add the below snippet

doc = frappe.get_doc("<doctype name>", "<name>")
frappe.get_doc(
                "WhatsApp Notification",
                notification_name
            ).send_template_message(doc)

Thanks, worked perfectly.

@ahassoun can you share me code to which doctype you implemented? Complete code from button creation to trigger.

You can not directly call a Python method from the client script.

Here's how you can properly trigger a server-side method to send a WhatsApp message from a custom button in the "Sales Invoice" DocType:

Correcting the Client-side Script

1. Variable Scope: The variable name isn't defined in your function. You should use frm.doc.name to get the name of the current document.
2. Asynchronous Server Call: Use frappe.call to make an asynchronous call to a server-side method. You cannot directly call server-side methods like send_scheduled_message from the client-side without this.

Here's a corrected version of the client-side script:

frappe.ui.form.on('Sales Invoice', {
    refresh(frm) {
        frm.add_custom_button(__('Send Invoice'), function() {
            // Use frm.doc.name to get the current document's name
            frappe.call({
                method: 'your_app_path.your_module_name.your_method', // Specify the correct path to your server-side method
                args: {
                    docname: frm.doc.name,
                    notification_name: 'WN-0001' // Assuming 'WN-0001' is the name of your WhatsApp Notification DocType instance
                },
                callback: function(r) {
                    if (!r.exc) {
                        // Handle successful message sending here, e.g., show a message to the user
                        frappe.msgprint(__('WhatsApp message sent successfully.'));
                    }
                }
            });
        }, __("Send WhatsApp Alert"));
    }
});

Required Server-side Method

You'll need to implement a server-side method that the client-side script can call. This method will retrieve the WhatsApp Notification document and then call its send_scheduled_message method with the appropriate arguments.

Here's an example of what the server-side method could look like:

# Example server-side method in your custom app
import frappe
from frappe.core.doctype.whatsapp_notification.whatsapp_notification import WhatsAppNotification

@frappe.whitelist()
def send_whatsapp_invoice(docname, notification_name):
    try:
        whatsapp_notification = frappe.get_doc('WhatsApp Notification', notification_name)
        doc = frappe.get_doc('Sales Invoice', docname)
        whatsapp_notification.send_scheduled_message(doc)
        return {'status': 'success'}
    except Exception as e:
        frappe.log_error(frappe.get_traceback(), 'send_whatsapp_invoice Error')
        return {'status': 'error', 'error': str(e)}

Make sure to replace 'your_app_path.your_module_name.your_method' in the client-side script with the actual path to this server-side method, such as 'your_app.doctype.sales_invoice.sales_invoice.send_whatsapp_invoice'.

This setup ensures that when the "Send Invoice" button is clicked, it will make an AJAX call to the specified server-side method, which then handles the process of sending the WhatsApp Notification. Remember to adjust the server-side method path and any DocType names or field names to fit your actual setup.
