I'm migrating from Parse to Parse server. Most of my code is made without promises. For this to work, I have to send the parameter: useMasterKey: true (where necessary) for each query / save.

For find and get queries or fetch objects, I have no problems, example:

Parse.com (find)

query.find({
    success: function(results) {
    //...

Parse Server (find)

query.find({useMasterKey: true
    }).then(function(results) {
    //....

Parse.com (fetch)

user.fetch({
    success: function(user) {
    //...

Parse Server (fetch)

user.fetch({useMasterKey: true,
    success: function(user) {
    //....

The problem is with each functions:

Parse.com (each)

query.each(function(comment) {
    //...

Parse Server (each)

query.each({useMasterKey: true
      }).then(function(comment) {
      //....

It does not work.

Thanks

Although the docs don't suggest that the useMasterKey option is supported for an each query, having tested and verified myself it is in fact possible. Syntax as follows:

query.each(callback, {useMasterKey: true})

Where callback is a function that is called for each result of the query.

The each method of a query support useMasterKey, it's passed as an argument after the callback function, that will be executed for each result of the query.

The syntax is:

query.each(function (object, error) {
        // Your function code
    }, {
        useMasterkey: true
})

Where object is a result for the query and error is a possible error that happened.

But, as shown here, it's better to just use useMasterKey for when you're actually changing something in the database:

query.each(function (object, error) {
    object.destroy({
        success: function (object) {
            console.log("Successfully destroyed object.")
        },
        error: function (error) {
            console.log("Error: " + error.code + " - " + error.message)
        },
        useMasterKey: true
   })
})
