How to get the current user in the HTML page to insert in the Flask Python database

Question

Hello I need to get the user who is logged in to the system for when he does an Update or Insert in the database enter his record, currently in the template I can already get the user name with this command

 {{ current_user.name }}

However when the user calls a route I would like to take this user to enter in the register of manipulations of the database, today I am using python and Flask in my application, could give me a help ?

Below the View code where I can catch the current user, but I need his data when calling the next route

{% extends "base.html" %}
{% block conteudo %}

{% include 'components/notification.html' %}

<div class="container">
    <div class="row">
      <div class="col-sm-3">
        <span><p>Olá <label  name="usuario">{{ current_user.name }}</label>, escolha o arquivo com as informações para começarmos </p></span>
      </div>
      <div class="col-sm-6">
              <form action = "/uploader" method = "POST" enctype = "multipart/form-data">
              <input type = "file" name = "file" />
              <input type = "submit"/>
              </form>
      </div>
      <div class="col-sm-3">

      </div>
    </div>
  </div>
{% endblock %}

The flask-login works with the current_user in global scope in the application, just as you use current_user in the template, you can use it in your route '/Uploader', just you import the current_user of own flask-login, see the example below, taking into account that the user is logged in:

from flask_login import current_user

@app.route('/uploader', methods = ['GET','POST'])
def uploader():
    print(current_user.nome)
