Hi, if you have lat and long in a specific model, you can use those coordenates for use gmap, you need a controller that pass those params. For example

@http.route('path', type='http', auth='public')
def url(self, **rec):
model = request.env['sale.order'].sudo().browse(id)
return request.render('path.qweb_id', {'model ': model})

After you need a qweb, in a xml file

<template id="remision_website" name="Remisión">
<t t-call="website.layout">

<script src="https://maps.googleapis.com/maps/api/js?key=Api&amp;callback=initMap" async="async" defer="defer"></script>
<script>
var map;
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
center: {lat: 19.3620379, lng: -99.130065},
zoom: 12,
});

var latitude_partner = <t t-esc="model.latitude_field"/>;
var longitude_partner = <t t-esc="model.longitude_field"/>;
var marker_partner = new google.maps.Marker({
position: {lat: latitude_partner, lng: longitude_partner},
map: map
});
}
</script>
<div id="map"></div>
</t>
</template>

You must use POST method in the controller, for example if you use box and the buttom send, each box is necesary have a key, and the controller is some similar to this

@http.route('/route/=<model("model.model"):feed>', type='http', auth="public", website=True)

def feedback_website_website(self, feed, **post):

if post.get('pregunta_1') or post.get('pregunta_2') or post.get('pregunta_5') or post.get('pregunta_10') or post.get('pregunta_11') or post.get('comentarios'):

for aux in range(10):

contador=str(aux+1)

exec("feed.pregunta_"+contador+" = post.get('pregunta_"+contador+"')")

feed.comentarios = post.get('comentarios_descrip')

feed.status_feedback = True

return request.redirect('/logistics/feedback/token='+str(feed.id)+'?submitted=1')
