Project Description

A Django app providing database and form fields for matrices (arrays of arrays).

Examples

Database Field

from django.db import models
from matrix_field import MatrixField

class MyModel(models.Model):
    matrix1 = MatrixField(datatype='float', dimensions=(3, 2))
    matrix2 = MatrixField(datatype='str', dimensions=(2,))

my_inst = MyModel(
    matrix1=[[5.1, -1.2], [4.2, 0.0], [3.14, 2.71]],
    matrix2=['a list', 'of strings'],
)
my_inst.full_clean()  # validates datatype, dimensions
my_inst.save()        # values stored in DB as json

m1 = my_inst.matrix1  # values retrieved as matrices
repr(m1)              # '[[5.1, -1.2], [4.2, 0.0], [3.14, 2.71]]'

Form Field

import json
from django import forms
from matrix_field import MatrixFormField

class MyForm(forms.Form):
    matrix = MatrixFormField(datatype='int', dimensions=(2, 1))

my_form = MyForm({
    'matrix': json.dumps([[2], [1]]),  # assignment of json representation
})
my_form.full_clean()                   # validates datatype, dimensions

m = my_form.cleaned_data['matrix']  # values retrieved as matrices
repr(m)                             # '[[2], [1]]'
