Access mongoose non-schema values in Jade

Question

Access mongoose non-schema values in Jade

I have a really weird problem in Jade where I cannot access the values that aren't defined in the Schema.

I'm using strict:false on my schema and saving values to it. My data looks like this:

{
 "title" : "This is a title in the schema",
 "notInSchema" : "This will never show up"
}

This works:

h1= post.title

This doesn't work:

h1= post.notInSchema

If I dump all my data into the template, I can see both pieces of data:

pre= JSON.stringify(options,null,'\t')      //{"title" : "This is a title in the schema", "notInSchema" : "This will never show up"}

If I add notInSchema to my schema, it shows up. How can I do this without adding it?

node.js
mongodb
express
mongoose
jade

Instead of passing the raw Mongoose document to Jade, pass its serialized version instead:

res.render('yourtemplate', {
  post : post.toJSON() // .toJSON() is also called by JSON.stringify()
});

I believe Mongoose only creates accessors on a document for fields that are in the schema. Any other fields, even though they are stored in the database, don't get one so can't be accessed directly.

The documentation seems to suggest something similar:

NOTE: Any key/val set on the instance that does not exist in your schema is always ignored, regardless of schema option.

EDIT: since you're dealing with result sets, you need to call toJSON on each document in it. The easiest way to do so is using map (hope I get the CF syntax right):

res.render "admin",
  title   : "Admin Dashboard"
  results : results
  users   : results.users.map (user) ->
    user.toJSON()
  messages: req.flash() || {}

Although that would still leave results 'unprocessed'. Alternatively, you could leave the mapping to the separate steps in your async.series. For instance:

 Company
   .find()
   .exec (err,companies)->
     next(null,companies.map (company) ->
       company.toJSON()
     )

Or use toJSON in your template on any object that you need to access those "unschema'd" properties for.

I use:

model.find({Branch:branch},function (err, docs){
if (err) res.send(err)

 res.render('index', 
    {tree: tree,
      articulos: JSON.parse(JSON.stringify(docs)) 
    })})
   });
