Triggering particular function inside afterSave

[srameshr]

Issue Description

How do I trigger a particular function inside afterSave for a given collection.

As of now I manually set a column called updateType and then inside the afterSave block I check for the value of updateType on the request object.

Steps to reproduce

Please include a detailed list of steps that reproduce the issue. Include curl commands when applicable.

In Parse.Cloud.define()

  var query = new MyCollection();
  query.set("updateType", "update-1");
  query.save();

In Parse.Cloud.afterSave()

Parse.Cloud.afterSave('MyNewCollection', function(request, response) {
  function a() {
  }

  function b() {
  }

  if(request.updateType === 'updated-1') {
    a(); // Call function a
  }
});

Is there any other way to do this. Any option that lets me choose what block of code should be executed inside afterSave after a collection had been saved.

Logs/Trace

You can turn on additional logging by configuring VERBOSE=1 in your environment.

@srameshr have you tried moving the function a() declaration outside of Parse.Cloud.afterSave?

[srameshr]

@natanrolnik Sorry, I dont understand how would that help. My point is, is there any way to pass some data from Collection.save() so that it appears in afterSave's request object.

As I have pointed out earlier, I am creating a column called updateType in my collection and setting it to some value each time on Collection.save().

[natanrolnik]

@srameshr Yes, there is, and this is the exact reason why the beforeSave and afterSave hooks exist.

You can do:

var myObject = request.object; to access the object;

And then var updateType = myObject.get("updateType");

You can read the docs here for more examples.

[natanrolnik]

I also recommend reading the JavaScript SDK guide.

@natanrolnik Tried that. It does not work the way I want. I am trying to set a property on request object in beforeSave and also trying to access the same property on the request object in afterSave. It gives out undefined

[natanrolnik]

Can you post some of your code?

[srameshr]

@natanrolnik Never mind. Setting a column called updateType makes more sense to my use case.

[natanrolnik]

So it's working now?

[srameshr]

Not with the beforeSave method.

[natanrolnik]

So could you give some extra information? What are you trying, what are the logs you see (when running with VERBOSE=1)?

[srameshr]

I will. Give me sometime. Have to run some errands.

@natanrolnik Here is what I am trying to achieve:
Consider User class. Now I have 3 parse define functions that modify and save the User collection.

Parse.Cloud.define('one', (request, response) => {
  // do some manipulation and save user object
})

Parse.Cloud.define('two', (request, response) => {
  // do some manipulation and save user object
})

Parse.Cloud.define('three', (request, response) => {
  // do some manipulation and save user object
})

Now the afterSave block

Parse.Cloud.afterSave(Parse.User, () => {

  // After save has 3 different functions which has to be run, based on which Parse.Cloud.define() function was called.

  function one() {}
  function two() {}
  function three(){}
  
  if( Parse.Cloud.define('one') was called ) {
    one() 
  }
  if( Parse.Cloud.define('two') was called ) {
    two() //
  }
  // So on
    
});

Now, afterSave will be triggered after every Parse.Cloud.define block is run. How do I identify, which Parse.Cloud.define block triggered the afterSave inside the afterSave so that I can invoke the right function.
