WaterlineJS/SailsJS: Query array attribute contains a value

Question

Suppose I have a model attribute tags: ['tag1', 'tag2', 'tag3']. I want to find models that have a certain tag. How do I do it?

It appears contains does a string contains. Not array contains which I need?

Answer 1

You can make use of the $in feature which allows you to filter from an array. You can write the query like

    Model.find({
    }).where({
       tags : {
        $in : tagArray
       }
    }).exec(function(err, data) {
      if(err) {
       console.log(data);
      } else {
       console.log(data);
      }
    });

Answer 2

   ModelName.find({tags: 'tag1'}).exec(function(err, tags){
        if (err){
           //handle error
           }
//tags is array of all data containing tags = 'tag1'
        console.log(tags);
        });
