Using the master key in a save hook

[juliusbtesh]

I am trying to refer to the Cloud Code example given for "beforeSave(Parse.Installation" and the function calls Parse.Cloud.useMasterKey(); But with the new Parse Server setups for the open source deployment, I read that I cannot use that line for using Mater Key anymore. How can I add that into this part of the function?

if (request.user) { request.object.set('user', request.user); } else { request.object.unset('user'); } response.success();

Thanks!

This is already covered in the migration guide, specifically in the document that covers compatibility issues between hosted Parse and Parse Server. We highly recommend going through each section to make sure your app transitions to Parse Server smoothly.

Thanks for the reply. I have read that guide and it says to use "useMasterKey: true" however I have not seen an example as the one I posted above with "useMasterKey: true" inside the function.

This is the reason why I have posted here.

Apologies, I misread your question. As a reminder you can use three backticks () followed byjsorjavascript` to denote a JavaScript code section, this will help with formatting and make it easier to understand the question.

If I understood correctly, you're asking for the proper way of implementing the following in Parse Server, given that useMasterKey() is not available and there is no explicit call to save():

Parse.Cloud.beforeSave(Parse.Installation, function(req, res) {
  Parse.Cloud.useMasterKey();
  if (request.user) { 
    request.object.set('user', request.user); 
  } else { 
    request.object.unset('user'); 
  } 

  response.success();
});

Yes sir. That is correct.

In this specific example you posted, I don't think you need to use the master key at all. The save should complete as expected, since the user updating their current installation should have write access to it.

Why would this exact code be on the Parse "AnyPic" example page if the Master Key isn't needed??

[hramos]

That's a great question. I don't think it is needed. Did you find otherwise?

[juliusbtesh]

I am not entirely sure because i cannot seem to get my app to receive the direct notifications even though the logs have no errors and the database shows an increased counter in the "installation" section

[juliusbtesh]

I don't think the above code will work, I am currently using without the master key. I have logged in with another device and noticed that the same user had a second 'installation' row in the database. Any ideas??

I have watched this video and I understand the way of using the master key
within the cloud code function, but I have asked how to use it with the
code I provided because it is a completely different function and I do not
see a place to put the master key.

You can read the Javascript API documentation and you will see you can do it like 4 different ways
https://parse.com/docs/js/api/classes/Parse.Object.html#methods_save

I've tested this and it works:

object.save(null, { useMasterKey: true });
