is it possible to use javascript to get data from django models db?

Question

I am trying to get the django model object to show on a html page. Of course when I tried to use {{ object }}, I get an error. How do I properly get the django data model and manipulate the attributes using javascript? the url: ``` ('^all_companies$', 'companies.views.all_companies') ``` the view: ``` def all_companies(request): companies = Company.objects.all().order_by('id')[:5]; return direct_to_template(request, 'all_companies.html', {'companies': companies} ); ``` the html: ``` {% block sidebar %} {% endblock %} ``` the js: ``` var tmp = {{ companies }} ```

Accepted Answer

In your view:

```
from django.core import serializers
json_serializer = serializers.get_serializer("json")()
companies = json_serializer.serialize(Company.objects.all().order_by('id')[:5], ensure_ascii=False)
```

In template:

```
var companies = '{{ companies|escapejs }}';
```

This is only for getting your data models into JS. For manipulating them, you should create some views that will get called from JS (by AJAX). They should probably return JSON.
