Re: New Document Validation

[John Le Brasseur <jo...@gmail.com>]

I have found an answer to this question [here][1].(In the
Adding Validation section about 2/3rds of the way down the article.(By
Robert Kowalski  August 28, 2014.))

The adapted code is: (hope I have copied it over correctly)

    {
    "_id": "_design/verifier",
    "_rev": "5-33f3ff3d650bf1594a9357af58153232",
    "validate_doc_update": "function (newDoc, oldDoc, userCtx, secObj) {\n
 if     (newDoc.type == \"xyz\"){\n    if (newDoc._deleted === true) {\n
   return;\n    }\n    if (!newDoc.abc) {\n      throw({forbidden:
\"Document must have an abc.\"});\n    }\n    if (!newDoc.def) {\n
 throw({forbidden: \"Document must have a def.\"});\n    }\n  if
(!newDoc.ghi) {\n      throw({forbidden: \"Document must have a ghi.\"});\n
   }\n  if (!newDoc.jkl.mno) {\n      throw({forbidden: \"Document must
have a jkl mno.\"});\n }\n  if (!newDoc.pqr.stu) {\n      throw({forbidden:
\"Document must have a pqr stu.\"});\n }\n if (!newDoc.vwx.yyy) {\n
 throw({forbidden: \"Document must have a vwx yyy.\"});\n   }\n   }\n  }"
    }

It works just as I wanted it to with the nested json objects.

Many thanks sir for that post.
