Gem to make it easier to use the PMP (Public Media Platform) API, which is a hypermedia API using the collection.doc+json format.
You can learn more about the PMP here:
https://github.com/publicmediaplatform/pmpdocs/wiki
Add this line to your application's Gemfile:
gem 'pmp'
And then execute:
$ bundle
Or install it yourself as:
$ gem install pmp
You should usually go through the PMP::Client as a convenience or start with a PMP::CollectionDocument.
Below is a basic guide, you can also see the examples for more info.
To see it used in a project, there is the PMP Importer which, as it says in the name, imports data from podcast feeds and www.prx.org into the PMP.
The importer super class is a good place to look.
# so you need a few things, like the endpoint, but default is "https://api.pmp.io"
endpoint = "https://api-sandbox.pmp.io"
# and you need credentials, the gem doesn't help you create these (yet)
client_id = "thisisnota-real-client-id-soverysorry"
client_secret = "thisisnotarealsecreteither"
# construct the client, setting some config in there
# this will automatically get a token as there is not one set
pmp = PMP::Client.new(client_id: client_id, client_secret: client_secret, endpoint: endpoint)
# or if you have a token already
token = 'thisisnotatoken'
pmp = PMP::Client.new(oauth_token: token, endpoint: endpoint)
# or if you want to get a token
pmp = PMP::Client.new(client_id: client_id, client_secret: client_secret, endpoint: endpoint)
oauth_token = pmp.token
# get the token string out of the token response
puts oauth_token.token
> 'thisisnotatoken'
# so let's get the root doc - an PMP::CollectionDocument instance
root = pmp.root
# or we can get it without the client, since PMP::CollectionDocument defaults to root
root = PMP::CollectionDocument.new(oauth_token: token, endpoint: endpoint)
# wanna get an attribute, act like it is a ruby attribute
puts root.guid
> '04224975-e93c-4b17-9df9-96db37d318f3'
# want to get the links, you can get a list of them by the rels
puts root.links.keys.sort
> ["creator", "edit", "navigation", "query"]
# don't feel like getting root first? Methods on the client get passed on to root
puts pmp.links.keys.sort
> ["creator", "edit", "navigation", "query"]
# want to get the creator link? (N.B. following a link always returns an Array, note use of `first`):
puts pmp.links["creator"].first
> #<PMP::Link href="https://api-sandbox.pmp.io/docs/af676335-21df-4486-ab43-e88c1b48f026">
# get the same thing as a method
puts pmp.creator.first
> #<PMP::Link href="https://api-sandbox.pmp.io/docs/af676335-21df-4486-ab43-e88c1b48f026">
# like the root doc itself, this is lazy loaded
# but ask for an attribute on there, and you'll get the doc loaded up
puts pmp.creator.first.guid
#### http get request to link href occurs, loads info about the creator
> 'af676335-21df-4486-ab43-e88c1b48f026'Once you have a doc, you can save or delete it like so:
# create a new blank doc, will generatr a guid automatically if not present
doc = PMP::CollectionDocument.new()
doc.title = "this is an example, ok?"
doc.save
# get that guid!
guid = doc.guid
# how about the link to self
self_href = doc.self.first.href
# get a new doc using self, could just have used the link, this is a bad example perhaps
doc = PMP::CollectionDocument.new(href: self_href)
# update an existing attribute
doc.title = "this is another awesome example, cool?"
# can add an attribute (doesn't check schema yet)
doc.adding_an_attribute = "this will get saved as a new attribute adding-an-attribute"
# can add links (doesn't check schema yet)
doc.links['some-new-link'] = PMP::Link.new({href:'http://somenewlink.io'})
new_link = doc.some_new_link
# save changes
doc.save
# never mind, delete it
doc.deleteVery big hat tip to the hyperresource gem: https://github.com/gamache/hyperresource
Think about integrating this lovely json schema parsing project: https://github.com/google/autoparse
or this one: https://github.com/hoxworth/json-schema
