A guide on looping through an array of objects to add information to a nested array in MongoDB

Currently, I am in the process of developing a blog application and working on an online editor feature. The schema I'm using for this project is outlined below:

 var blogSchema = restful.model('blog-schema', mongoose.Schema({
   title: String,
   preview: String,
   content: [{tag: String, body: String}],
   comments: [{ body: String, date: Date}],
   createdAt: {type: Date, default: Date.now}
 }

For the client-side implementation, I am utilizing react to POST data in the following format:

 [{"type":"h2","body":"azeaeazeae"},{"type":"p","body":"azeaeazeae"}]

In my server side code with express(), I have the following logic:

 blogSchema.update(
  {title: "please work AGAIN"},
  {
     $pushAll: {
      content: test
     }
 },
 function(err, stat, docs) {
  console.log(stat);
 }
)

After checking the stored data with POSTMAN, I noticed that the output was as follows:

"content": [    
{
  "tag": "[object Object],[object Object]",
  "_id": "57b2eced869e03821d446c38"
}

The challenge I am facing now is how to iterate through this array of objects on the server side and correctly push each item to its designated place within the tag and body fields.

Answer №1

After some searching, I finally found the solution:

Below is the code snippet that worked for me:

app.post('/admin', function(req, res) {
   var test = req.body;

   test.map(function(test, i) {
   blogSchema.update(
   {title: "please work AGAIN"},
    {
      $push: {
        content: {
          test: test.type,
          body: test.body
        }
      }
    },
    function(err,stat,dude){
      console.log(stat);
    })
})

I was able to successfully map the request body and use the $push method in MongoDB. Apologies for posting the question earlier, but I'm thrilled to have figured it out!
