can i model.get, specifying the type to return, with the field defined in the schema?

[Derick Bailey]

Hi!

I have a sub-sub-sub document that is changing... the old / original version of this field is defined as an object with 3 fields in it:

  stepFamily: {

    name: {type: String, required: true, default: ""},

    description: {type: String, required: true, default: ""},

    slug: {type: String, required: true, default: ""},

  },

the new version of the field needs to change this to a simple string

  stepFamily: {type: String, required: true, default: ""},

after changing my schema definition, i'm trying to write some code that will transform the original data in to the new string... and i'm running in to a problem. I can't get my original object out of the field.

every time I try to .get the field, specifying Object as the type to retrieve:

myObj.get("stepFamily", Object); 

it returns the value as '[object Object]' - the .toString() representation of an object literal... it's as if the .get method is ignoring the type parameter, because the field is defined in the schema as a type.

has anyone run in to this problem? know of a workaround for this, so that I can get my original object out of the field?

Thanks,

This is kind of "standard" for doing in-database schema updates like this.  

1) Update your schema to have both fields:

stepFamily: Object

strStepFamily: String

2) Copy and format the data from stepFamily to strStepFamily

3) Update your schema file again:

stepFamily: String

strStepFamily: String

4) Copy all the information back

5) Delete strStepFamily

I forgot to mention 2a: validate that everything made it.

Also forgot step 0: backup your database.
