Lazy-Loading module for Django

Project description

=====
Django-Lazyloader
=====

Django-Lazyloader is a simple Django app which helps displaying Django objects as either HTML or JSON.

Quick start
-----------

1. Add "lazyloader" to your INSTALLED_APPS setting like this::

INSTALLED_APPS = (
...
'lazyloader',
)

2. Include the lazyloader URLconf in your project urls.py like this::

url(r'^lazyloader/', include('lazyloader.urls')),

3. Run `python manage.py migrate` to create the demo models.

4. Run `python manage.py loaddata lazyloader_initial.json` to load the initial data for the live demo.

5. Run `python manage.py collectstatic` to collect the static files of the live demo.

6. To allow your models to be displayed by Django-Lazyloader, define a VALID_LAZY_MODELS variable in your settings.py
file like this::

VALID_LAZY_MODELS = [
'MyApp.MyModel',
'MyOtherApp.MyOtherModel',
]

7. Create html templates and assign them to your models by adding a LAZY_TEMPLATES variable to your project's
settings.py file like this::

LAZY_TEMPLATES = {
'MyApp.MyModel': 'myapp/mylazytemplate.html',
'MyOtherApp.MyOtherModel': 'myotherapp/myotherlazytemplate.html'
}


8. Run the development server and visit http://localhost:8000/lazyloader/demo for the live demo.

9. To access your the first 10 entries of your model 'Myapp.MyModel' in the JSON format visit
http://localhost:8000/lazyloader/myapp-mymodel-json-0-10/

10. To access your the first 10 entries of your model 'Myapp.MyModel' in the HTML format visit
http://localhost:8000/lazyloader/myapp-mymodel-html-0-10/

11. To create custom queries you can add the get parameters 'column' and 'search_value' to your url:
http://localhost:8000/lazyloader/myapp-mymodel-html-0-10/?column=name&search_value=smith
This url will execute a django-query that looks like this::

MyApp.MyModel.objects.filter(name=smith)

12. The variable that is passed to the templates is called 'models' so if you want to iterate over the queryset in a
template you have to do it like this::

{% for model in models %}
{{ model.fieldname }}
{% endfor %}
