Django Model Parser

The parser that detects django models from the provided python script. It's uses Python's AST (Abstract Syntax Trees) module.

Usage

Example usage:

import modelparser

print modelparser.loads("""

class Group(models.Model):
    name = models.CharField(max_length=255)

class User(models.Model):
    first_name = models.CharField(max_length=255)
    last_name = models.CharField(max_length=255)
    is_active = models.BooleanField()
    groups = models.ManyToManyField(Group)

""")

The result:

{
    'Group': [{
        'type': 'string',
        'name': 'name'
    }],
    'User': [{
        'type': 'string',
        'name': 'first_name'
    }, {
        'type': 'string',
        'name': 'last_name'
    }, {
        'type': 'boolean',
        'name': 'is_active'
    }, {
        'type': 'many-to-many',
        'name': 'groups',
        'relationship': 'Group'
    }]
}

And also you can parse file like objects:

import modelparser

print modelparser.load(open("foo.py"))
