Load JSON from file

I need to load the JSON from a file on the device, instead of from the internet. How would I go about this with Maglev?

My JSON look like this:

But their rationale was never the money alone but the product feedback and consumer validation that the 8,000 funders could offer. The product builds on Fuelband and Fitbit’s shortcoming and offers a product that syncs via touch, works when biking and swimming and offers an open API. The price was also very favorable for the early funders, starting at $49 and now post-funding retails at $99.

      body: "<p class='body'><p>A small town in Wales made jeans for over three decades. As much as 10% of the population were involved in the manufacturing. One day the factory closed down and moved away. Left were the mastery of how to make fantastic jeans. The Hiut Denim Company was started to put those skills to work again and to breathe life into their beloved town.&nbsp;<br><br>Their story - which also happens to be true - resonates with people and their jeans have become very popular across the world among the early adopter crowd through earned media. But what makes them even more unique is that they are - in a world that is frantically multi-tasking and diversifying - committed to only doing one thing and doing it really well: jeans made to last. They only offer two types of denim in two different cuts for men - women have to wait until later this year. And every year they have a new release with upgrades based on their user’s feedback.<br><br>The jeans are sold primarily via their online shop but now also through select local retailers. Every pair of jeans have an unique number on the inside which can be registered with HistoryTag.com to capture it’s timelime to be shared with the world via Twitter. Hiut Denim creates the first tag with the name of the jeans master, the date of manufacturing and a few photos. The second tag is usually by the new owner, telling his followers that he has received his first Hiut jeans.<br><br>The jeans are designed to be simple and understated. If it wasn’t for their distinct logo - a red owl - on the rivet of the left back pocket the jeans would be unrecognizable for the untrained eye. But once you have owned one for a few weeks you start recognizing others wearing the very same jeans and that could be the start of a very beautiful friendship. It could be the selvedge, the high quality denim, the stitching or how they age beautifully into being yours. Hiut recommends not washing a new pair of jeans for at least 6 months so that your personal body fats in combination with everyday wear can allow for the jeans to hug you in the right places and create real wrinkles that could be yours.<br><br>Hiut Denim is not really a brand but the next generation lovemark. They have been brilliant at taking an iconic piece of clothing and making it matter again on a new level. Everything with their story resonates with people: make to last, honor craftsmanship, do things well, care about your community, care about people, think long-term, work hard and have fun.&nbsp;<br><br>Everything Hiut shares via their Twitter stream, weekly email newsletter and inspirational physical yearbook is turning into social objects that starts conversations. But it’s never about the transactional experience of the jeans but the transformational experience of having a purpose, a strong culture and making what matters. That’s what their brand “experience” is about. It’s not about them, it’s about you.<br><br>In a world where cheaper, faster and more short-term seems to be the prevalent modus operandi, Hiut is the honest, transparent and authentic challenger of the mindless business technorati culture. They are living their dream by using technology as an instrument, not a crutch and we are all invited to participate in their conquest of happiness without any false product promises or commitments to buying their jeans. That said, once you have tried on a pair of their jeans you never want to give them back no matter what. And that is genius.</p></p>"

I have 3 models:

class Publication < Maglev::Model
  remote_attributes :id, :headline

  has_many :issues

  collection_path ''
  member_path ''
end

class Issue < Maglev::Model
  remote_attributes :id, :headline, :color, :name, :date

  has_many :articles
  belongs_to :publication

  collection_path '/articles'
  member_path '/article/:id'
end

class Article < Maglev::Model
  remote_attributes :id, :headline, :lead, :image, :body, :byline, :name, :url

  belongs_to :issue
end

How would I go about loading my JSON from a file instead of an url and how would you go about linking it up to the models when my JSON file doesn't have a /publications extension?

Is this even possible with Maglev?

You can load the file using standard Cocoa (string = NSString#stringWithContentsOfFile:encoding:error:), parse it with something like my_hash = BW::JSON.parse(string), and then initialize your Publication object with Publication.new(my_hash).

Awesome thanks. I'll give it a shot.   — Sent from Mailbox for iPad
