There is a router with handlers for GET and POST requests related to documents. When creating new documents and posting them, the redirection works smoothly. However, upon initial page load after creation, only existing documents are displayed. It's only upon refreshing the page that the newly created documents appear. Any insights on why this happens and how to resolve it?
The issue within your code arises from not allowing the update function to finish before proceeding. :) When you instruct the database to save the documents using:
Document.update({'_id': doc.id}, d, {overwrite: true}...
Since mongo performs updates asynchronously, this code will only query and move on without waiting for the actual update to occur. To rectify this, it is essential to execute res.redirect('/documents'); in the callback function (which executes after the update completes).
Therefore, your revised code should resemble the following:
Document.update({'_id': doc.id}, d, {overwrite: true}, function(err, raw) {
if (err) return handleError(err);
res.redirect('/documents');
});
Here is an example of Promise.all as requested by @XavierB
//Gather all promises into a single array
let promises = [];
promises.push(Document.update({'_id': doc.id}, d, {overwrite: true}));
//Wait for all promises to resolve
Promises.all(promises).then(function(){
//All promises have resolved successfully
res.redirect('/documents');
}).catch(err => {
//An error occurred with any of the promises.
console.log(err);
});;
Executing this function asynchronously may result in a delay before completion. To ensure proper execution, consider utilizing async/await or .then to trigger the redirect to '/' within the callback function.
