how to push value in to object's property dynamically in mongoose?
You need to define your path using the dot notation instead of square brackets:
`authencity.${authencityType}`For instance authenticity.fake
try:
const result = await News.findOneAndUpdate({ name: newsName }, { $push: { `authencity.${authencityType}`: email } }, { new: true });Also note that in mongoose's findOneAndUpdate version you need to pass new: true parameter in order to return modified document
const newColumn = `authencity.${authencityType}`;const result = await News.findOneAndUpdate({ name: newsName }, { $push: { [newColumn]: email } }, { new: true });Here, I have created a dynamic string to construct a column name using template literal and then enclosed it with [], so mongo will consider this a column name
