Build Status NPM version Dependency Status Development Dependency Status Gittip donate button

Import MongoDB collections into DocPad collections.

Inspired by https://github.com/simonh1000/docpad-plugin-mongo and based on https://github.com/docpad/docpad-plugin-tumblr/

Install

docpad install mongodb

Configuration

Simple example

Add the following to your docpad configuration file:

plugins:
  mongodb:
    collections: [
      connectionString: "mongodb://localhost/blog" # format is "mongodb://username:password@hostname:port/dbname?options"
      collectionName: "posts"
      relativeDirPath: "blog"
      extension: ".html"
      sort: date: 1 # newest first
      meta:
        layout: "blogpost"
    ]

Fancy example

plugins:
  mongodb:
    collectionDefaults:
      connectionString: "mongodb://localhost/blog" # format is "mongodb://username:password@hostname:port/dbname?options"

    collections: [
      {
        # connectionString is imported from the defaults
        collectionName: "posts"
        relativeDirPath: "blog"
        extension: '.html.eco'
        sort: date: 1 # newest first
        injectDocumentHelper: (document) ->
          document.setMeta(
            layout: 'default'
            tags: (document.get('tags') or []).concat(['post'])
            data: """
              <%- @partial('post/'+@document.tumblr.type, @extend({}, @document, @document.tumblr)) %>
              """
          )
      },

      {
        collectionName: "comments"
        extension: '.html.markup'
        sort: date: -1 #oldest first
        query: {isSpam: false}
        meta:
          write: false
      },

      {
        connectionString: "mongodb://localhost/stats"
        collectionName: "stats"
        docpadCollectionName: "websiteStats"
        extension: ".json"
      }
    ]

Config details:

Each configuration object in collections inherits default values from collectionDefaults and then from the built-in defaults:

    connectionString: process.env.MONGOLAB_URI || process.env.MONGOHQ_URL || "mongodb://localhost/localdev"
    relativeDirPath: null # defaults to collectionName
    extension: ".json"
    injectDocumentHelper: null # function to format documents
    collectionName: "mongodb" # name of the collection in mongodb
    docpadCollectionName: null # defaults to collectionName
    sort: null # http://documentcloud.github.io/backbone/#Collection-comparator
    meta: {} # automatically added to each document
    query: {} # optional MongoDB query to select a sub-set of the documents in the collection

The default directory for where the imported documents will go inside is the collectionName. You can override this using the relativeDirPath plugin config option.

The default content for the imported documents is JSON data. You can can customise this with the injectDocumentHelper plugin configuration option which is a function that takes in a single Document Model.

If you would like to render a template, add a layout, and change the extension, you can do it via the meta configuration option or you can get fancy and do this with (for example) the eco and partials plugins and following collection configuration:

extension: '.html.eco'
injectDocumentHelper: (document) ->
  document.setMeta(
    layout: 'default'
    tags: (document.get('tags') or []).concat(['post'])
    data: """
			<%- @partial('post/'+@document.tumblr.type, @extend({}, @document, @document.tumblr)) %>
			"""
  )

The sort field is passed as the comparator to Query Engine which tries it as a MongoDB-style sort first and then a Backbone.js comparator second.

The query is a standard MongoDB query and can be used to filter the documents before importing them into your DocPad database.

Creating a File Listing

As imported documents are just like normal documents, you can also list them just as you would other documents. Here is an example of a index.html.eco file that would output the titles and links to all the blog posts from the simple example above:

<h2>Blog:</h2>
<ul><% for post in @getCollection('posts').toJSON(): %>
	<li>
		<a href="<%= post.url %>"><%= post.title %></a>
	</li>
<% end %></ul>
