Get slug from object in view won't work - mongodb

Question

I have created a new object named Project, that contains a gallery and some other fields in it. In the view, I'm showing some data from it and I want to put a link to previous and next project. I already managed to get the previous project but when I try to get the slug from it, somehow it doesn't work.
This is the Project model:
var keystone = require('keystone');
var Types = keystone.Field.Types;
/**
* Project Model
* ==========
*/
var Project = new keystone.List('Project', {
map: { name: 'title' },
autokey: { path: 'slug', from: 'title', unique: true }
});
Project.add({
title: { type: String, required: true },
state: { type: Types.Select, options: 'draft, published, archived', default: 'draft', index: true },
author: { type: Types.Relationship, ref: 'User', index: true },
publishedDate: { type: Types.Date, index: true, dependsOn: { state: 'published' } },
category: { type: String, required: false },
description: { type: Types.Html, wysiwyg: true, height: 150 },
shortDescription: { type: Types.Html, wysiwyg: true, height: 100 },
credits: { type: Types.Html, wysiwyg: true, height: 100 },
galleries: { type: Types.Relationship, ref: 'Gallery', many: false },
color: { type: String, required: false }
});
Project.schema.virtual('content.full').get(function() {
return this.content.extended || this.content.brief;
});
Project.defaultColumns = 'title, state|20%, author|20%, publishedDate|20%';
Project.register();
This is the controller:
var keystone = require('keystone');
exports = module.exports = function(req, res) {
var view = new keystone.View(req, res);
var locals = res.locals;
// Set locals
locals.section = 'projects';
locals.filters = {
project: req.params.project
};
locals.data = {
projects: [],
previousProject: []
};
// Load the current project
view.on('init', function(next) {
var q = keystone.list('Project').model.findOne({
state: 'published',
slug: locals.filters.project
}).populate('galleries');
q.exec(function(err, result) {
locals.data.project = result;
next(err);
});
});
//Load other projects
view.on('init', function(next) {
var q = keystone.list('Project').model.find({state: "published", publishedDate: {$lt: locals.data.project.publishedDate}}).sort('-publishedDate').limit(1);
q.exec(function(err, results) {
locals.data.previousProject = results;
next(err);
});
});
// Render the view
view.render('project');
};
And this is the view:
<div class="container">
<p>{{{data.project.title}}}</p>
<p>—</p>
<p>{{{data.project.category}}}</p>
{{#if data.project.galleries}}
{{#each data.project.galleries.images}}
<img src="{{url}}" />
{{/each}}
{{/if}}
<p>full project: {{data.previousProject}}</p>
<p>slug: {{data.previousProject.slug}}</p>
{{#if data.previousProject}}
<a href="/projects/{{data.previousProject.slug}}" >Previous project</a>
{{/if}}
</div>
Somehow, {{data.previousProject}} shows the correct record info but when I do {{data.previousProject.slug}} it returns nothing at all. I've been scratching my head against this for hours but I can't find where is the issue. Thanks in advance!!

Answer 1

I finally found what the issue was: in the controller I'm using model.find whereas I should be using model.findOne if I know I only need one record and I want to directly get the values from it with .slug. Using limit(1) was not enough.
