In my latest project, I have successfully integrated a MongoDB database with a MEAN stack web application. Currently, the application is able to display the most recent set of data from the database. However, I am now faced with the challenge of refining this display to show only one specific section of the data, out of the total 50 sections available.
My approach involves using post.find to retrieve and sort the data in order to display the most recent record from the database. However, I am encountering difficulties in filtering this data further to only display information related to a particular section. The current data structure can be viewed here: https://i.sstatic.net/8TDJG.jpg. As shown in the image, the data is categorized by "S0", followed by corresponding details for each section labeled "S1", "S2", and so on. Ideally, I would like to query and display only the data associated with "S0".
exports.list = function (req, res) {
Post.find().sort({ _id: -1 }).limit(1)
.then(function (posts) {
return res.status(200).json({
status: 200,
data: posts,
message: 'Success'
})
})
.catch(function (err) {
return res.status(400).json({
status: 400,
message: err.message
});
});
}
I suspect that modifying the find query is necessary, but I am unsure about how to specify the retrieval of data specifically pertaining to "S0" instead of the range from "S0" to "S49". Any guidance on this matter would be greatly appreciated.
Thank you
