File upload Queries

[pra17shant]

Upload files to a remote file server

• you can use a custom integration or library to transfer the file to the remote server after saving it locally. One popular library for transferring files to remote servers is paramiko .

import paramiko
from frappe.utils.file_manager import save_file

# default Frappe folder
file_doc = save_file(filedata, filename, dt, dn)

hostname = 'remote_server_ip'
username = 'remote_username'
password = 'remote_password'
remote_folder = '/path/to/remote/folder'

# Connect to the remote server using SSH
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname, username=username, password=password)

# Transfer the file to the remote server
sftp = ssh.open_sftp()
local_path = file_doc.file_url
remote_path = f"{remote_folder}/{filename}"
sftp.put(local_path, remote_path)

sftp.close()
ssh.close()

IF YOU HAVE NAS (Network Attached Storage) for Storage like Synology then

• you can use various methods such as FTP, SFTP, or SCP. We can transfer files to a using the paramiko library and SFTP:

# Define the Synology NAS details
hostname = 'nas_ip_address'
port = 22  # Default SFTP port for Synology NAS
username = 'nas_username'
password = 'nas_password'
remote_folder = '/path/to/remote/folder'

By Help of this you can achieve some logic to any kind of doctype

• Client Script

frappe.ui.form.on("YourDoctype", {
    upload_file_button: function(frm) {
        var file_input = document.createElement("input");
        file_input.type = "file";
        file_input.accept = "image/*";  // Specify the accepted file types here

        file_input.onchange = function() {
            var file = file_input.files[0];
            var reader = new FileReader();

            reader.onload = function(e) {
                var filedata = e.target.result;

                frappe.call({
                    method: "upload_file_to_remote_server",
                    args: {
                        filedata: filedata,
                        filename: file.name
                    },
                    callback: function(response) {
                        if (response.message) {

                            frappe.msgprint("File transferred successfully.");
                        } else {

                            frappe.msgprint("File transfer failed.");
                        }
                    }
                });
            };

            reader.readAsDataURL(file);
        };

        file_input.click();
    }
});

*Server Script

import paramiko
@frappe.whitelist()
def upload_file_to_remote_server(filedata, filename):
    remote_hostname = 'remote_server_ip'
    remote_username = 'remote_username'
    remote_password = 'remote_password'
    remote_folder = '/path/to/remote/folder'
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(remote_hostname, username=remote_username, password=remote_password)
    sftp = ssh.open_sftp()
    remote_path = f"{remote_folder}/{filename}"
    sftp.putfo(filedata, remote_path)
    sftp.close()
    ssh.close()
    return True

Hope you understand how do that…!
Thanks…!
