Correct yummly API call for a recipe - web-services

I'm trying to use the Yummly API. I've noticed that some of their developers have answered other questions here, so I'm hoping to catch their eye. I used the documentation at the yummly developer site https://developer.yummly.com/documentation#IDs.
Specifically here is my get request:
<http://api.yummly.com/v1/api/recipe/Avocado-cream-pasta-sauce-recipe-306039>
Which returns this:
Please include X-Yummly-App-ID and X-Yummly-App-Key
Seems like this is a sensible thing, except that I don't see anywhere in the documentation for the single recipe call where I'm supposed to insert that info. Any one out there know how to properly format this?

or include them as URL parameters:
_app_id=app-id&_app_key=app-key
https://developer.yummly.com/documentation#IDs
Try this:
http://api.yummly.com/v1/api/recipe/Avocado-cream-pasta-sauce-recipe-306039?_app_id=ID&_app_key=KEY

You need to take the URL you mentioned in the question and add your authentication parameters to it. So it becomes:
http://api.yummly.com/v1/api/recipe/Avocado-cream-pasta-sauce-recipe-306039?_app_id=ID&_app_key=KEY
Instead of ID and KEY insert the application id and key from your account on developer.yummly.com

API RESTful Resource Naming

I always have the doubt that you can see below when i need to create theresource URLs for a REST API. I wonder if some one can help me.
Let's suppose that i have two models.
User
Post
User can submit his own posts and can comment his own and another posts.
Main resources URLs for User would be:
GET /users # Retrieve all users.
POST /users # Create a new user.
GET/DELETE/PUT /users/{user_id} # Get, remove and update an user.
Main resource URLs for Post would be:
GET /posts # Retrieve all posts.
POST /posts # Create a new post.
GET/DELETE/PUT /posts/{post_id} # Get, remove and update a post.
My problem come when for example i want:
Top 10 submitters (filter for a parameter(external link, discussion, all)). The URL should be:
GET /users/top?type=ext
GET /users/top?type=disc
GET /users/top # for all
Or maybe it should be:
GET /users?top=ext
GET /users?top=disc
GET /users?top=all
The same but with posts:
Top 10 commented post (filter for a parameter(external link, discussion, all)). The URL should be:
GET /posts/comments?type=ext
GET /posts/comments?type=disc
GET /posts/comments # for all
Or maybe it should be:
GET /posts?top=ext
GET /posts?top=disc
GET /posts?top=all
Any of above options are good for you or it should be another way?
Regards
I like to think of the REST URI as a model representation in itself.
So /users/top doesn't make a lot of sense but /posts/comments seems to be fine (as comments could also be a different model). But for your case, I recommend other set of query parameters as they're widely used for filtering & sorting requests. So in your case, I'd recommend something like:
GET /users?sort=ext&order=desc&limit=10
which would help me understand that I'm requesting 10 user resources which have been sorted for ext in the descending order. (you can even change it to type=ext if you want)
As usual; REST doesn't care what spellings you use.
One place you might look for inspiration is... stack overflow itself. Do these URI look familiar?
/questions?sort=newest
/questions?sort=featured
/questions?sort=votes
The API has pretty decent documentation, which will also offer hints at decent spellings to deal with paging and search ranges.
That said, IMDB takes a different approach - The Shawshank Redemption uses a straight forward "I am an element of a collection" spelling
http://www.imdb.com/title/tt0111161/
But the top rated titles of all time? they appear as a chart
http://www.imdb.com/chart/top
But i want to know if there is a standard according to #Hawkes answer or there is no standard at all.
No standard at all; just local spelling conventions. Which is, to some degree, part of the point of REST: the server can use whatever spellings for URI make sense, and the client just "follows its nose" based on its understanding of the processing rules for the media type and the data provided by the server.

Correct REST API URL format for related objects

I'm designing a REST API where, amongst others, there are two objects.
Journey
Report
For each Journey there are many Reports enroute, and each Report has exactly one associated Journey.
A user might create a Journey using the API as follows...
POST /journey/
Then retrieve the details...
GET /journey/1226/
The first question is, if a user wanted to post an Report to their Journey, which is the 'correct' URL structure that the API should impose? This seems intuitive to me...
POST /journey/1226/report/
...or is this the case...
POST /report/
...whereby in the latter, the Journey ID is passed in the request body somewhere?
The second question is, how might one go about implementing the first case in a tool such as the Django REST framework?
Thanks!
The URL/URI structure is almost completely irrelevant. It is nice to be able to read it, or easily change or even guess it, but that is it. There is no "requirement" official or unwritten how they should look like.
The point is however, that you supply the URIs to your clients in your responses. Each GET will get you a representation that contains links to the next "states" that your client can reach. This means the server has full control over URI structure, the client usually has to only know the "start" or "homepage" URI, and that's it.
Here is an article which discusses this question, has some good points: http://www.ben-morris.com/hackable-uris-may-look-nice-but-they-dont-have-much-to-do-with-rest-and-hateoas/
Pass for the second question :) I didn't use that particular framework.

CookieAuthenticator restlet

I have built some RESTful api's with REstlet 2.3.4. I've been using HTTP_BASIC which let the browser prompt for credentials but it's time for a proper login form. I figure the easiest way to implement this is CookieAuthenticator. I can't find full working examples on github/google. I am sure i'm over looking them can someone provide a working example implementing CookieAuthenticator in Restlet?
I did get this to work after all. I have a longer answer here with some code examples. First, i was missing the fact that CookieAuthenticator is a filter and HAS the logic to handle login and logout. You need to create EMPTY ServerResources with a method annotated with #Post that has nothing in the body. Second, extend CookieAuthenticator and overwrite isLoggingIn(..) and isLoggingOut(..) with the code found in the link.

RESTful API and Foreign key handling for POSTs and PUTs

I'm helping develop a new API for an existing database.
I'm using Python 2.7.3, Django 1.5 and the django-rest-framework 2.2.4 with PostgreSQL 9.1
I need/want good documentation for the API, but I'm shorthanded and I hate writing/maintaining documentation (one of my many flaws).
I need to allow consumers of the API to add new "POS" (points of sale) locations. In the Postgres database, there is a foreign key from pos to pos_location_type. So, here is a simplified table structure.
pos_location_type(
id serial,
description text not null
);
pos(
id serial,
pos_name text not null,
pos_location_type_id int not null references pos_location_type(id)
);
So, to allow them to POST a new pos, they will need to give me a "pos_name" an a valid pos_location_type. So, I've been reading about this stuff all weekend. Lots of debates out there.
How is my API consumers going to know what a pos_location_type is? Or what value to pass here?
It seems like I need to tell them where to get a valid list of pos_locations. Something like:
GET /pos_location/
As a quick note, examples of pos_location_type descriptions might be: ('school', 'park', 'office').
I really like the "Browseability" of of the Django REST Framework, but, it doesn't seem to address this type of thing, and I actually had a very nice chat on IRC with Tom Christie earlier today, and he didn't really have an answer on what to do here (or maybe I never made my question clear).
I've looked at Swagger, and that's a very cool/interesting project, but take a look at their "pet" resource on their demo here. Notice it is pretty similar to what I need to do. To add a new pet, you need to pass a category, which they define as class Category(id: long, name: string). How is the consumer suppose to know what to pass here? What's a valid id? or name?
In Django rest framework, I can define/override what is returned in the OPTION call. I guess I could come up with my own little "system" here and return some information like:
pos-location-url: '/pos_location/'
in the generic form, it would be: {resource}-url: '/path/to/resource_list'
and that would sort of work for the documentation side, but I'm not sure if that's really a nice solution programmatically. What if I change the resources location. That would mean that my consumers would need to programmatically make and OPTIONS call for the resource to figure out all of the relations. Maybe not a bad thing, but feels like a little weird.
So, how do people handle this kind of thing?
Final notes: I get the fact that I don't really want a "leaking" abstaction here and have my database peaking thru the API layer, but the fact remains that there is a foreign_key constraint on this existing database and any insert that doesn't have a valid pos_location_type_id is raising an error.
Also, I'm not trying to open up the URI vs. ID debate. Whether the user has to use the pos_location_type_id int value or a URI doesn't matter for this discussion. In either case, they have no idea what to send me.
I've worked with this kind of stuff in the past. I think there is two ways of approaching this problem, the first you already said it, allow an endpoint for users of the API to know what is the id-like value of the pos_location_type. Many API's do this because a person developing from your API is gonna have to read your documentation and will know where to get the pos_location_type values from. End-users should not worry about this, because they will have an interface showing probably a dropdown list of text values.
On the other hand, the way I've also worked this, not very RESTful-like. Let's suppose you have a location in New York, and the POST could be something like:
POST /pos/new_york/
You can handle /pos/(location_name)/ by normalizing the text, then just search on the database for the value or some similarity, if place does not exist then you just create a new one. That in case users can add new places, if not, then the user would have to know what fixed places exist, which again is the first situation we are in.
that way you can avoid pos_location_type in the request data, you could programatically map it to a valid ID.

How can I retrieve all comments on a Facebook post using the php SDK?

I'm building an app which allows users to post articles to their facebook wall. When an article is posted, I retrieve the post id and store that in the database along with the rest of the article details. Now I want to be able to show the comments made on that post when someone views the article in my site; I would also like to allow users to add comments to the post from my site.
I know that the user is always logged into Facebook when they are viewing the article, as the system checks for that earlier on.
I've been using the PHP SDK, and thought all I had to do was something like:
$post_comments = $facebook->api('/' . $post_id . '/comments');
However, when I do this, I get the following error:
Fatal error: Uncaught GraphMethodException: Unsupported get request. thrown in /APP_PATH/facebook/src/facebook.php on line 560
I really don't have much of a clue what I'm doing here, to be honest, as I'm very new to the Facebook Graph API, and I can't seem to find a lot of documentation on it.
Can anyone tell me what I should be doing here, or point me to some documentation I could read about it?
Thanks!
It should work.
Here is the code I am using which is working for me.
$comments = $facebook->api($postid . '/comments');
Make sure your postid is a valid one.
Alternatively, you can directly type that url in browser to get details like this
https://graph.facebook.com/<postedid>/comments
Please refer this link for further reference
http://developers.facebook.com/docs/reference/api/Comment/
I don't know what your PHP library is doing, but you can actually access comments by reading graph.facebook.com/<post_id>/comments. Indeed, try with this one from the doc.
Are your sure of your post id? Try to call the buggy function with 19292868552_118464504835613 as post id. It has to work.
