如何在 JavaScript 中使用 Mongoose 动态更新文档？

Question

I need to update attributes from a MongoDB document based on the value from the data-target from an HTML object. However, I don't know how to insert its data-target in the JSON.stringify

const save = (_id) =>{
    const token = localStorage.getItem('token')
    const saves= document.querySelectorAll(".flaticon-diskette")

    saves.forEach(function(save){

        console.log(`.input-${save.getAttribute("data-target")}`)
        const input = document.querySelector(`.input-${save.getAttribute("data-target")}`)
        var target = save.getAttribute("data-target")

        save.addEventListener('click', () =>{
            fetch(`https://janfa.gharsnull.now.sh/api/auth/edit/${_id}`,{
                method: 'PUT',
                headers: {
                    'Content-Type': 'application/json',
                    authorization : token,
                },
                body: JSON.stringify( { target : `${input.value}`} ), 
            }).then(console.log("done"))
        })
    })
}

target is supposed to contain the data-target of each save but instead it's read as "target" by JSON.stringify . I tried using a template strings, but it seems like JSON.stringify won't let me use it in the first field. What can I do?

Answer 1

To update a document using Mongoose you need to use the yourDocumentModel.findByIdAndUpdate() (if it's one document at a time) function.

If you've installed all the packages as you'll need to do is call the async function to update the document in the DB

Solved it just by changing body: JSON.stringify( { target: '${input.value}'} ) for body: JSON.stringify( { [target]: '${input.value}'} )
