I have a model, using postman I am sending request to this model, and in response I am getting the complete record(suppose 25 columns I have), so in response I am getting 25 columns back. I want to see only one column in the response, how can I change that. In javascript file, I have already written before save and after save methods.

Instead of all the columns detail, i want only one column detail in response which i m getting in postman

Solution 1:

For one time requests, you can pass on the filter query object in the get request with fields options specifying the columns you need.

Example: To only return the id, and name column.

{
  "fields": {
    "id": true,
    "name": true
  }
}

fields can also be supplied on server side like this:

yourRepository.find({fields: ['id', 'name']});

Solution 2:

To disable returning the columns in every request, specify hiddenProperties in model definition.

Like below:

@model({
  settings: {
    hiddenProperties: ['password'] //
