[Solved] Meteor Simple Schema Validate and clean object

help
1

I have defined a schema for a meteor mongo collection using smpl-schema to validate and clean object before insert and update data.

import SimpleSchema from 'simpl-schema';
const schema = new SimpleSchema({
  name:String,
  age:Number,
  address:{
   type:String,
   optional:True
  }
}, {
  clean: true,
});

My data :

let doc = {
  name:' ',
  age:10,
}

Here my function validate data:

function validateData(){
let validationContext = schema.newContext();
validationContext.validate(doc);
if (!validationContext.isValid()) throw JSON.stringify(validationContext.validationErrors())

return true
}

But it’s error and it’s output : Error: Cannot convert undefined or null to object [ValidateDataError]

First I believe you need to define the clean key as an object with the cleaning options defined like so:

clean: {
    filter: true,
    autoConvert: true,
    removeEmptyStrings: true,
    trimStrings: true,
    getAutoValues: true,
    removeNullsFromArrays: true,
  },

Next, since you are validating manually and not using Collection2, you’ll need to call the clean method manually.

Sure, you just have to call the clean method on the schema and pass it the document. It will return a cleaned document that you can pass to the validate method.

function validateData(){
  let validationContext = schema.newContext();
  let cleanDoc = shema.clean(doc); //Clean the document before validation
  validationContext.validate(cleanDoc);
  if (!validationContext.isValid()) throw JSON.stringify(validationContext.validationErrors())
    return true
}
