Project Description

djcroco is a custom Django model field to add support for the Crocodoc API.

It behaves like standard FileField so you can still use most of its properties (e.g. name, size, url etc) while having extra ones to play with Crocodoc API.

djcroco is supported by Incuna (an awesome company I work for!).

Requirements

  • Python 2.6.x, 2.7.x
  • Django 1.3.x, 1.4.x, 1.5.x
  • crocodoc 0.1.1

Python 3.x will be supported soon!

Installation

To install djcroco, simply run:

pip install djcroco

Include in urls.py:

url(r'', include('djcroco.urls')),

Define Crocodoc API token in settings.py:

CROCO_API_TOKEN = '<api_token>'

Or alternatively as env variable:

export CROCO_API_TOKEN='<api_token>'

When optional parameters for URLs are used (see below for more details) - then you need to add djcroco to INSTALLED_APPS:

INSTALLED_APPS += ('djcroco',)

And load its template tags in the template you wish to use them in:

{% load croco_tags %}

Usage

Define the field in model you wish to extend:

from django.db import models

from djcroco.fields import CrocoField


class Example(models.Model):
    name = models.CharField(max_length=255)
    document = CrocoField()

    def __unicode__(self):
        return self.name

Custom thumbnails size

You can pass thumbnail_size like so:

document = CrocoField(thumbnail_size=(150, 150))

Where tuple is represented as (width, height).

If you do not pass custom thumbnail size, the default will be used (100x100). The maximum dimensions for thumbnail is 300x300.

Thumbnail caching

By default the thumbnail will be generated every time template gets rendered and this involves hitting Crocodoc API for each thumbnail. It could be time expensive if you have many items on a single page. To avoid above issue you can point to a field where the thumbnail will be saved and served from there the next time.

class Example(models.Model):
    name = models.CharField(max_length=255)
    document = CrocoField(thumbnail_field='my_thumbnail')
    my_thumbnail = models.ImageField(upload_to='whatever/')

Note that the thumbnail_field must be a type of ImageField.
