fetching data from findAll and pass it to ejs file

fetching data from findAll and pass it to ejs file - javascript

I'm trying to fetch data from mysql and pass the data to ejs file. I want to display the passed data as a html datatable. but it seems to not work.
I'm using sequelize and node js and ejs.
Here is how i implemented findAll() method
router.get('/list', function (req,res, next) {
player.findAll()
.then( players => {
console.log(data);
var data = res.json(players);
res.render("list", {data:data})
});
});
And here is where i want the data to be displayed.
<table>

Thank you for helping in advance

Try passing players directly to the template
router.get('/list', function (req,res, next) {
player.findAll()
.then(players => {
res.render("list", {data: players})
});

How to print a div that has a canvas using JavaScript and html?

Hi I wanted to print a specific div that has a canvas consisting of a chart. I had written a script to print the specific div in my HTML body tag but it returns everything except the graph.
This is what I want:
This is what I get:
How can I achieve the results shown in image 1? Thanks in advance.
This is my code for the script:
<script>
//Print specific div
function printFunc() {
var tagname = $('#div-report').prop("tagName").toLowerCase();
var attributes = "";
var attrs = document.getElementById("div-report").attributes;
$.each(attrs, function(i, elem) {
attributes += " " + elem.name + " ='" + elem.value + "' ";
})
var divToPrint = $('#div-report').html();
var head = "<html><head>" + $("head").html() + "</head>";
var allcontent = head + "<body onload='window.print()' >" + "<" + tagname + attributes + ">" + divToPrint + "</" + tagname + ">" + "</body></html>";
var newWin = window.open('', 'Print-Window');
newWin.document.open();
newWin.document.write(allcontent);
newWin.document.close();
};
</script>
This is my code for the front-end HTML(in case you need it):
<body class="d-flex flex-column">
<div class="container p-2 pb-0 mt-5 pt-3" id="admin-dashboard">
<h2 class="pt-3 pb-5 display-6">Report Summary</h2>

You treat "filter" and "sort" as two different operations but those are two operations that need to be applied at the same time (so that sorting does not overwrite filtering result and vice versa). Also you are not using Vue reactivity at all. This is perfect use case for computed
This computed has 3 inputs:
unfiltered and no sorted original array
active filter
active sort

How to update a Datatable via Ajax call

I have a table that displays the content from a model whenever someone accesses the URL /project_page.
On that page, the user can add files and I would like the table to be updated in real-time without having to constantly refresh.
For that purpose, I have tried to implement an Ajax function that updates the table content every few seconds. Since it is something that was suggested a few years ago here
I think the function is implemented and I receive the data properly in the Ajax success function but I don't know how to 'inject it' to the table.
I would also like to know if there is a more optimal or pythonic way to achieve this result.
urls.py

file_hist = form.save(commit=False)
file_hist.user = request.user
# file is saved
file_hist.save()
file_hist_results = FileHistory.objects.all().filter(user=request.user)
context['file_hist_results'] = file_hist_results
print(type(context['file_hist_results']))

js
var intervalID = setInterval(updateTable, 10000);
function updateTable()
{
$.ajax({
method: "GET",
url: "/project_page_ajax/",
success: function(response) {
$("#ittFileUploadTable").hide(); // first hide the current table
$("#ittFileUploadTable").append(response); // and append the data
}
});
}

The solution largely depends on what the JSON response is.
HTML
If your response is the actual HTML chunk to be displayed, looking somewhat like this:
<tr><!-- Some tds --></tr>
<tr><!-- Some tds --></tr>
<tr><!-- Some tds --></tr>
<!-- ... -->
<tr><!-- Some tds --></tr>
Then you can do it like this:
document.querySelector("#ittFileUploadTable tbody").innerHTML = yourTemplate;
JSON
If your data is JSON, then it would be great to create a template function, like this one:
function fileUploadRecordTemplate(record) {
return `
<td>record.filename</td>
<td>record.uploaded</td>
<td>record.updated</td>
<td>record.user</td>
<td>
<button id="delete-itt-file" type="button" class="btn btn-secondary">
<svg xmlns="http://www.w3.org/2000/svg" width="25" height="25" fill="currentColor" class="bi bi-trash-fill" viewBox="0 0 16 16">
<path d="M2.5 1a1 1 0 0 0-1 1v1a1 1 0 0 0 1 1H3v9a2 2 0 0 0 2 2h6a2 2 0 0 0 2-2V4h.5a1 1 0 0 0 1-1V2a1 1 0 0 0-1-1H10a1 1 0 0 0-1-1H7a1 1 0 0 0-1 1H2.5zm3 4a.5.5 0 0 1 .5.5v7a.5.5 0 0 1-1 0v-7a.5.5 0 0 1 .5-.5zM8 5a.5.5 0 0 1 .5.5v7a.5.5 0 0 1-1 0v-7A.5.5 0 0 1 8 5zm3 .5v7a.5.5 0 0 1-1 0v-7a.5.5 0 0 1 1 0z"></path>
</svg>
</button>
</td>
`;
}
And hydrate your tbody like this:
let output = [];
for (let record of data) output.push(fileUploadRecordTemplate(record));
document.querySelector("#ittFileUploadTable tbody").innerHTML = yourTemplate;
Fiddle
let index = 1;
//t1
function updateT1() {
//We generate some HTML, but if you get an HTML from server-side, then you can
//skip this part
let template = "";
let rows = parseInt(document.getElementById("t1rows").value);
for (let i = 0; i < rows; i++) {
template += `
<tr>
<td>${index++}</td>
<td>${index++}</td>
<td>${index++}</td>
<td>${index++}</td>
</tr>
`;
}
//This is the actual operation which refreshes the HTML
document.querySelector("#t1 > tbody").innerHTML = template;
}
//t2
function fileUploadRecordTemplate(record) {
return `
<tr>
<td>${record.filename}</td>
<td>${record.uploaded}</td>
<td>${record.updated}</td>
<td>${record.user}</td>
<td>

I found a solution!
As #mark_b sugested, I used the datatables Ajax instead of jQuery AJAX
Now it works, here is my code:
$('#ittFileUploadTable').DataTable( {
responsive: true,
autowidth: false,
destroy: true,
deferRender: true,
ajax: {
url: '/project_page_ajax/',
type: 'GET',
data: {},
dataSrc: ""
},
columns: [
{"data": "fields.filename"},
{"data": "fields.uploaded"},
{"data": "fields.updated"},
{"data": "fields.user"},
{"data": "pk"},
],
columnDefs: [
{ className: 'text-center', targets: [1] },
{
