Views not refreshing correctly using SailsJS - node.js

Question

in my code, i have a view called "show.ejs" which shows client details. the proble; now is that if i update client details (image, associated docs, ...) the content remains the same and changes only if i refresh the page ( by F5 ) .
this my update and show actions in ClientController :
findOne : function(req,res){
Client.findOne({
id : req.param('id')
})
.populate('docs')
.populate('sites')
.exec(function(err,client){
if(err) throw err;
if(client) {
return res.view('client/show', {
client : client
});
} else {
return res.redirect('/client');
}
})
},
update : function(req,res){
var name = req.param('name'),
id = req.param('id'),
town = req.param('town'),
adress = req.param('adress'),
postalCode = req.param('postalCode'),
telephone = req.param('telephone'),
email = req.param('email'),
fax = req.param('fax'),
responsable = req.param('responsable'),
website = req.param('website'),
activity = req.param('activity');
Client.findOne({id : id}).exec(function(err,client) {
if(err) console.log(err);
client.name = name;
client.town = town;
client.adress = adress;
client.telephone = telephone;
client.fax = fax;
client.website = website;
client.email=email;
client.responsable=responsable;
client.postalCode=postalCode;
client.activity = activity;
client.save();
req.file('logo').upload({
dirname: require('path')
.resolve(sails.config.appPath+'/assets/uploads/clients/logos/')
}, function (err, logo) {
if (err) throw err;
if(typeof logo !== 'undefined' && logo.length > 0 ) {
require('fs').unlink('./assets/uploads/clients/logos/'+client.logo, function(err){
if(err) console.log(err)
client.logo = require('path').basename(logo[0].fd);
client.save();
})
}
return res.redirect('/client/'+client.id );
});
})
}
and this is how i setup the view :
<div class="row">

Answer 1

Actually following your code, the problems reside in
client.save()
which is an asynchronous function.
the problem is you are changing the client and you are not waiting for the changes to be saved to upload the logo and reload the data.
here's the official doc, which is stating that model.save has a callback to it.
client.save(function(){
/*your code */
})

Answer 2

The view, with those EJS functions is doing what is expected to do. You see, you are not providing some way to magically change data on-the-fly. Instead what EJS and your controller is doing is this: Get all data needed - with findOne -> Put that data on the view - with EJS and <% %> markers -> Render and serve a static HTML document - res.view.
If you need data to change on the fly you need a more powerful framework on the frontend, like Vuejs or Angular... EJS is meant to assembly a static page with dynamic data ONCE. Take a look at the docs
