Assembly in action
# views.py from assembly import (Assembly, response, request, HTTPError) # Extends to Assembly makes it a route automatically # By default, Index will be the root url class Index(Assembly): # index is the entry route # -> / index(self): return "welcome to my site" # method name becomes the route # -> /hello/ hello(self): return "I am a string" # undescore method name will be dasherize # -> /about-us/ about_us(self): return "I am a string" # The class name is part of the url prefix # This will become -> /blog class Blog(Assembly): # index will be the root # -> /blog/ index(self): return [ { "title": "title 1", "content": "content" }, ... ] # with params. The order will be respected # -> /comments/1234/ # 1234 will be passed to the id comments(self, id): return [ { comments... } ] # It's also Restful class Api(Assembly): # method named get, automatically accepts get method # -> GET /api/ get(self): return { "message": "This will show on get call" } # method named post, automatically accepts post method # -> POST /api/ post(self): return { "message": "This will show on POST call" } # Can change the response to json # -> /api/about/ @response.json about(self): return { "name": "Assembly", "version": "1.0.1" } # endpoint with different method # -> POST /api/submit/ @request.post submit(self): return { "message": "This will show on POST call only" } # This will throw an Unauthorize error error(self): raise HTTPError.Unauthorized()

Quickstart
This quickstart will allow us to go with Assembly from 0 to 100!
1. Install Assembly
Install Assembly with pip install assembly
It is highly recommended to use a virtualenv, in this case let's use VirtualenvWrapper (you can use any that is convenient for you)
mkvirtualenv my-first-app workon my-first-app pip install assembly
2. Initialize your application
Initialize Assembly with asm-admin init
CD into the folder you intend to create the application, then run asm-admin init
.
This will setup the structure along with the necessary files to get started
cd app-dir asm-admin init
Upon initialization you should have a structure similar to this:
-- / |- wsgi.py |- config.py |- requirements.txt |- main |- __init__.py |- __models__.py |- templates |- Index |- index.html |- layouts |- base.html |- static |- cli.py |- __data__/
3. Edit your first view
# main/__init__.py from assembly import (Assembly, response) class Index(Assembly): index(self): return { "title": "Assembly is awesome", "content": "That is a true fact" } @response.json api(self): return { "name": "Assembly", "version": "x-to-infinity" }
4. Edit your template
4.0 Edit base layout
<!-- main/templates/layouts/base.html --> <!doctype html> <html lang="en"> <head> <title>{% block title %}{% endblock %}</title> </head> <body> <div class="container"> {% block body %}{% endblock %} </div> </body> </html>
4.1 Edit Index/index.html
<!-- main/templates/Index/index.html --> {% extends 'main/layouts/base.html' %} {% block title %}Welcome to my Assembly Site {% endblock %} {% block body %} <div> <h1>{{ title }}</h1> </div> <div> {{ content }} </div> {% endblock %}
5. Serve your first application
If everything is all set, all you need to do now is run your site:
asm-admin serve
It will start serving your application by default at 127.0.0.1:5000
Two endpoints will be available:
http://127.0.0.1:5000/ http://127.0.0.1:5000/api/
