A quotes database in python.

1. Check out source code

   git clone git://github.com/Ramblurr/pyqdb.git

2. Install dependencies

   pip install -U -r requirements.txt

3. Setup Database

   ./sql_setup.py```
   
   

4. Start server

   python pyqdb.py

pyqdb tries very hard to be RESTful. As such there is no special API URI. Instead you can make requests to the same URIs used for browsing the page in HTML, but pass the Accept: application/json (or one of the custom mimetypes below) and pyqdb will return nifty json for the resource.

pyqdb treats HTML and JSON as two representations of the same state. It tries to respect the Accept and Content-Type headers at all times. In the spirit of HATEOAS there is no documentation describing every possible API call. Toss a GET at the root URI (with the Accept JSON header) to see the available resources.

pyqdb makes use of the Link header to hint to the consumer where to go next. A good example of this is pagination. When GETting the list of latest quotes the link header contains the URI to the next and previous pages.

$ curl -I -H "Accept: application/json" vtbash.org/quotes
HTTP/1.1 200 OK
Content-Type: application/json
Link: </quotes?start=15>; rel="next"
Content-Length: 4911

Similarly, when fetching a blank skeleton for quote submission the Link header contains the hint on where to submit the quote.

curl -i -H "Accept: application/json" vtbash.org/quotes/new
HTTP/1.1 200 OK
Date: Tue, 09 Aug 2011 16:42:32 GMT
Content-Type: application/json
Link: </quotes>; rel="submit"
Content-Length: 98

{"body": "Quote here", "link": {"href": "/quotes", "method": "post", "rel": "submit"}, "tags": []}

You can see above that pyqdb also embeds link information into the JSON using the link JSON object. Possible values for this key are:

• href (required)- the URI to the resource being linked
• rel (required) - the relation of the link to the containing resource
• method (optional) - the suggested method to use, if no method is specified GET is the assumed default
• title (optional) - a human readable description of the link

pyqdb uses relative URIs wherever possible.

Link Relations

self The href of a link with this relation refers to the containing resource.

pyqdb/quote The href of a link with this relation can be used to fetch a quote resource.

pyqdb/quote/new The href of a link with this relation can be used to create a quote resource.

pyqdb/quote/cast-vote The href of a link with this relation can be used to cast a vote on a quote.

pyqdb/quotes The href of a link with this relation can be used to fetch a list of quotes.

pyqdb/quotes/next pyqdb/quotes/prev The href of a link with these relations can be used to fetch the next or previous page of results.

pyqdb/tag The href of a link with this relation can be used to fetch a quote resource.

pyqdb/tags The href of a link with this relation can be used to fetch a list of tags.

Media Types

application/vnd.pyqdb-quote A representation of this media type contains a quote document.

application/vnd.pyqdb-quotes A representation of this media type contains a list of quote documents.

application/vnd.pyqdb-tag A representation of this media type contains a tag document.

application/vnd.pyqdb-tags A representation of this media type contains a list of tag documents.

application/vnd.pyqdb-vote A representation of this media type contains a vote.

application/vnd.pyqdb-error A representation of this media type contains an error.

Most of the time mimetypes will have a +format suffix indicating which format the data is in. For example ths is a JSON formatted quote:

application/vnd.pyqdb-quote+json

Currently only the json format is supported.
