Vee-Validate validateAll() with scope

问题

I have a scenario where I have sectioned out (scoped) a form so that I can validate small chunks at a time using the following function.

validateScope (scope) {
  return this.$validator.validateAll(scope);
}

I want to do one final validation of the entire form before I submit it to the server; however, validateAll() doesn't seem to pick up inputs that have been added to a scope. I've also tried just validating each scope and then submit the form if they are ALL valid, but I am not sure how to do that since everything is asynchronous.

validateAll () {
   let valid = true;

   // Not sure how to build this function since validateScope is asynchronous
   _.each(this.names, (name, index) => {
     if(this.validateScope('name-' + index)){
       valid = false;
     }
   });

   return valid; // Always returns true even though the _.each should set it to false
}

As mentioned in my comment, your code will end up looking something like this:

validateAll () {
   let valid = true;

   let validations = []
   _.each(this.names, (name, index) => {
     validations.push(this.validateScope('name-' + index))
   });

   return Promise.all(validations)
     // consolidate the results into one Boolean
     .then(results => results.every(r => r))
}

Then, of course, you'll have to use validateAll as a promise:

this.validateAll().then(isValid => {
  if (!isValid) {
    //do whatever you need to do when something failed validation
  } else {
    // do whatever you need to do when everything is valid here
  }
})
