Sync events on local dev chain

Hey so you advised me to use beforeSave but I can’t change how the event will be saved right ?

#42

What you mean that you can’t change?

#43

As of now events are saved depending on the abi I would like to change how they are saved, edit the scheme in some sort of way.

Because right now all I can do is to create another Table which will be fed by the beforeSave trigger.

#44

You can change the fields names in the original abi that you use too, you should be able to make changes in event schema like adding a new column in beforeSave too

#45

My contracts are already deployed so i can’t change the abi. But is it possible to edit the field names also?
Could you show me how ?
Btw thank you very much for your help, what a team !

It doesn’t matter what you have as field name in your contract, when you add an event for sync you can change the name field for a column in something else directly in the abi that you paste there.

#48

Moralis.Cloud.beforeSave("Review", (request) => {
  const comment = request.object.get("comment");
  if (comment.length > 140) {
    // Truncate and add a ...
    request.object.set("comment", comment.substring(0, 137) + "...");
    request.object.set("new_field", comment.substring(0, 137) + "...");
  }
});
