Project description

A collection of utilities to help in Django Projects

TravisButton

Installation

pip install django-tiamat

Add to your Python path or setup.py install and add 'tiamat' to your INSTALLED_APPS setting.

Usage

This is intended for general use in any project to save time writing helpers that are common to most projects.

View Decorators

as_json will return a JSON response:

from tiamat.decorators import as_json

@as_json
def some_view(request):
    #do something
    return {'key': 'value'}

as_jsonp will return a JSONP response:

from tiamat.decorators import as_jsonp

@as_jsonp('callback')
def some_view(request):
    #do something
    return {'key': 'value'}

`http://.../?callback=myFunctionCall`

returns `myFunctionCall({"foo": "1"})`

Model Mixins

SlugMixin will add a slug field (named slug) to your model that will be automatically generated from a field called ‘name’ on saving. If you wish to override the default field to generate the slug from set make_slug_from on the model. See the source for more details.

Generic Manager

A simple way to add a manager that overrides the queryset returned.

So this:

class SomeManager(models.Manager):
    def get_query_set(self):
        return super(SomeManager, self).get_query_set().filter(this=that)


class SomeModel(models.Model):
    # define the model
    objects = models.Manager()
    custom_objects = SomeManager()

Becomes this:

from tiamat.models import GenericManager

class SomeModel(models.Model):
    # define the model
    objects = models.Manager()
    custom_objects = GenericManager(this=that)

Pagination Helper

A simple way to handle pagination of your querysets:

from tiamat.paginate import page_objects

page = page_objects(Something.objects.all(), 25, 2)

Where 25 is objects per page and 2 is the current page number

ID Encoder

This is a good when you are using IDs in your urls. An example would be a link generated to confirm an email address, or a link generated to reset a user’s password.

Make sure you set the setting URL_ENCODER_KEY to something different than your SECRET_KEY then you can:

from tiamat.urlencoder import encoder

encoder.encode_id(id)
encoder.decode_id(identifier_string)

Email

send_async_email provides an easy helper to send email using a template:

from tiamat.mail import send_async_email

send_async_email(
    'path/to/template.html',
    {'name': 'Steve'},
    'Hello',
    [user.email for user in User.objects.all()]
)

Template Tags

As an alternative to using form.as_p() or form.as_table() and dealing with that you can define a generic template for forms by overriding the template tiamat/_form.html and using it like so:

{% load tiamat_tags %}
{% render_form form %}
