Narrative

In these narrative docs, we'll go through creating a todo application.

Installation

pip install guillotina

Generating the initial application

Guillotina comes with a cookiecutter template for creating a base application.

First, install cookiecutter if it isn't already installed.

pip install cookiecutter

Then, run the generate command:

guillotina create --template=application

Enter guillotina_todo for package_name.

Then, install your package:

cd guillotina_todo
python setup.py develop

Configuring

The scaffold produces an initial config.yaml configuration file for you.

You can inspect and customize your configuration. Most notable is the database configuration. If you want to run a development postgresql server, the scaffold ships with a Makefile that provides a command to run a postgresql docker: make run-postgres.

Creating to do type

Types consist of an interface (schema) using the excellent zope.interface package and a class that uses that interface.

Create a content.py file with the following:

from guillotina import configure
from guillotina import schema
from guillotina import Interface
from guillotina import interfaces
from guillotina import content


class IToDo(interfaces.IItem):
    text = schema.Text()


@configure.contenttype(
    type_name="ToDo",
    schema=IToDo)
class ToDo(content.Item):
    """
    Our ToDo type
    """

Then, we want to make sure our content type configuration is getting loaded, so add this to your __init__.py includeme function:

    configure.scan('guillotina_todo.content')

Running

You run you application by using the guillotina command runner again:

guillotina serve -c config.yaml

Creating your todo list

Create container first:

curl -X POST --user root:root \
  -H "Accept: application/json" \
  -H "Content-Type: application/json" \
  -d '{
  "@type": "Container",
  "title": "ToDo List",
  "id": "todo",
  "description": "My todo list"
  }' "http://127.0.0.1:8080/db/"

Install your todo list application:

curl -X POST \
  --user root:root \
  -H "Accept: application/json" \
  -H "Content-Type: application/json" \
  -d '{
  "id": "guillotina_todo"
  }' "http://127.0.0.1:8080/db/todo/@addons"

Add todo items:

curl -X POST \
  --user root:root \
  -H "Accept: application/json" \
  -H "Content-Type: application/json" \
  -d '{
  "@type": "ToDo",
  "text": "Get milk"
  }' "http://127.0.0.1:8080/db/todo"

curl -X POST \
  --user root:root \
  -H "Accept: application/json" \
  -H "Content-Type: application/json" \
  -d '{
  "@type": "ToDo",
  "text": "Do laundry"
  }' "http://127.0.0.1:8080/db/todo"

Get a list of todo items:

curl -H "Accept: application/json" --user root:root "http://127.0.0.1:8080/db/todo"
