Waterline error: "Unknown rule: default"

I'm getting the following error when calling

.create()
on a model.

Model:

attributes: {
user : {
type: 'integer'
},
number : {
type: 'string'
}
}


Call:

sails.models.phone.create({
user: 2,
number: '5555555555',
updated_at: Sun Nov 27 2016 16:59:45 GMT-0800 (PST)
});


Error:

How do I fix this?

I've looked into similar errors, but none of my models have a
default
attribute, including the
phone
model shown above. Why is this happening, and how do I solve it?




Solution

So it turns out that a Waterline call of
.update()
changes the input information. I had written a function to create or update waterline models, and when they fixed the auto updated_at issue, they must've altered the incoming info.

My previous code that did not work:

createOrUpdate: function(model, primary, data){
return model.update(primary, data)
.then(function updateCB(updated){
if (updated.length == 0){
return model.create(data) //data here had an added updated_at field
.then(function(created){
return created;
});
}

if (updated.length > 0){
updated = updated[0];
}
return updated;
});
}


My new code that does work:

createOrUpdate: function(model, primary, data){
const data1 = JSON.parse(JSON.stringify(data)); // deep copy
const data2 = JSON.parse(JSON.stringify(data)); // deep copy
return model.update(primary, data1)
.then(function updateCB(updated){
if (updated.length == 0){
return model.create(data2)
.then(function(created){
return created;
});
}

if (updated.length > 0){
updated = updated[0];
}
return updated;
});
}

Answer

You can't call update with:

updated_at: Sun Nov 27 2016 16:59:45 GMT-0800 (PST) 

Updated_at is automatically filled field. Remove it from request (call as you call it) and it will work.
