Error when validating model with two equal array names

[thomastvedt]

My model looks like this: Activity

• Id
• CategoryIds []
• Name
• Task
  • Id
  • CategoryIds['vacation']

When I call model.validate(), I get the following error: Uncaught TypeError: Cannot use 'in' operator to search for '0' in vacation

Is this because I have two attributes named "CategoryIds" in my model? One attribute "activity.CategoryIds[]" and one nested attribute "activity.Task.CategoryIds[]". Maybe flattening isn't working? Is this a bug, and can it be fixed? :-) Or am I doing something wrong? (validation works on simpler models).

Can you please include your model definition including its validation block? On Sep 18, 2015 5:46 AM, "Thomas Tvedt" [email protected] wrote:

The error appears even though there is no validation-block defined. (when I call model.set(), which calls .validate() etc.)

This is what my Activity-model looks like while debugging (js-code is minimal):

it fails in "flatten(obj, into, prefix) backbone-validation.js:78

var flatten = function (obj, into, prefix) {
into = into || {};
prefix = prefix || '';

_.each(obj, function(val, key) {
  if(obj.hasOwnProperty(key)) {
    if (!!val && _.isArray(val)) {
      _.forEach(val, function(v, k) {
        flatten(v, into, prefix + key + '.' + k + '.');
        into[prefix + key + '.' + k] = v;
      });
    } else if (!!val && typeof val === 'object' && val.constructor === Object) {
      flatten(val, into, prefix + key + '.');
    }

    // Register the current level object as well
    into[prefix + key] = val;
  }
});

return into;
};

When flattening Task.CategoryIds, _.isArray(key) is true.. then there is a recursive call to: flatten(obj="con", into=.., prefix="Task.CategoryIds.0."){

now on line 82 it fails, because obj is a string and not an array. obj = "con": _.each(obj, function(val, key) {

Uncaught TypeError: Cannot use 'in' operator to search for '0' in con

Activity.Task.CategoryIds is an array of strings. Is there something wrong with my model?
