Python framework bottle notes

Introduction

bottle is a lightweight framework for python. The main body seems to be only one file. If you google, many articles in Japanese will appear, so I will omit the details.

http://bottlepy.org/docs/dev/index.html

It will be updated gradually.

Environment

My machine

OS X Yosemite Ver 10.10.5

Install python (2.7.10)

Implementation

• Fixed because 2.7.11 is inserted by default
• Is 2.7.11 buggy? The bottle didn't work

brew edit python

• Put in with homebrew

brew install python
abridgement

which python
/usr/local/bin/python

• Upgrade of pip

pip2.7 install --upgrade pip

• Upgraded setuptools

pip2.7 install --upgrade setuptools

• Module installation
• Image processing system for the time being * pillow * matplotlib
• If you add matplotlib, you can add various other things. Is there a dependency? ??

pip2.7 install pillow

Bottle environment construction

• bottle installation

pip2.7 install bottle

• Prepare a nice code
• main.py does the routing
• top.py is logic

/path/to/bottle/app/main.py

from bottle import route, run, static_file, url
from top import index

@route('/static/<filepath:path>')
def static(filepath):
    return static_file(filepath, root="./static")

@route('/')
def top():
    return index(url)

run(host='localhost', port=8080, debug=True, reloader=True)

/path/to/bottle/app/top.py

from bottle import template, view
import const

@view("index")
def index(url):
    return dict(url=url, design_path=const.DESIGN_PATH)

/path/to/bottle/app/const.py

DESIGN_PATH = './static/startbootstrap-sb-admin-2-1.0.8'

• Start bottle

python main.py

• Access the following URL with a browser

http://localhost:8080/

Directory structure

• So far
• Example in static directory

myapp
    ├── const.py        //Constant
    ├── main.py         //routing
    ├── static          //Set up static files
    │ ├─ css            //Example: putting css
    │ ├─ js             //Example: putting js
    │ └─ img            //Example: Putting an image
    ├── top.py          //Top screen processing
    └── views           //Template storage
        └── index.tpl   //Top screen template

Function memo

• run
• Function to start the server
  • host
• Host
  • port
• Port
  • debug
• Whether to enter debug mode
  • reloader
• Whether to automatically restart the server when saving source changes
• If this is not set to True, the server will have to be restarted manually for the source changes to take effect.

others

• Those put in with pip entered the following path

/usr/local/lib/python2.7/site-packages/
