Visualizaçõesnodejs ejs how to display specific field from array of objects in ejs template
I am trying to display a specific field of the first object that is inside a array of objects.
index.js:
router.get('/chatroom', ensureAuthenticated, (req, res) => {
const user = req.user
chatroom.find({chatroom_users: user.name}, function (error, data) {
res.render("chatroom", {
data,
user: req.user});
})
}
})chatroom.ejs:
<script>
<% for (var i = 0; i < data.length; i++) { %>
var chatroom_message0 = "<%= data[i].chatroom_message.date%>"
<% } %>
</script>This is the structure in MongoDB:
But I can only so far show the entire object but not the specific field that I want, in this case the field "date".
I have tried many different combinations for example:
"<%= data[i].chatroom_message["date"]%>"
"<%= data[i].chatroom_message._date%>" But I can't get it to work, so any help would be appreciated.

the date is inside a array so it makes sense that you can't select like that depending on your data format it can be used like this:
<= data[i].chatroom_message[0].date %>
if the format is
data = [
{chatroom_message : {date, user_name, message} },
{chatroom_message : {date, user_name, message} },
]
<% for( let i = 0; i < data.length; i++ ) { %>
<% const {chatroom_message} = data[i] %>
<% for( let j = 0; j < chatroom_message.length; j++ ) { %>
<%= chatroom_message[j].date %>
<% } %>
<% } %>
or if the format is
chatroom_message = [
{date, user_name, message}
]
<% for( let i = 0; i < chatroom_message.length; i++ ) { %>
<%= chatroom_message[i].date %>
<% } %>

I figured it out, I made a typo mistake in my mongodb model I had written "dates"in the model instead of "date" thats why it didn't show up.
