Transforming Django models into JSON format to be utilized as a JavaScript object

Looking to retrieve model data as an object in Javascript, I've been using the following approach in my Django view:

var data = {{ data|safe }};

Here is how my view is set up:

context = {
    'data': {
        'model1': serializers.serialize('json', model1.objects.all()),
        'model2': serializers.serialize('json', model2.objects.all()),
    }
};

The issues I'm encountering are:

1) An error occurs in JS unless I apply "safe" to the context variable,

2) Even with "safe", the object is returned as a string rather than a usable object (e.g. accessing data.model1[0] yields "[" instead of the first element).

Seeking guidance on the correct way to achieve this functionality.

Answer №1

The issue lies in the fact that even though the contents of data adhere to proper JSON format, the data object itself is a Python dictionary and not valid JSON.

An effective approach would involve splitting up the variables:

var data = {
    modelA: {{ data.modelA|safe }},
    modelB: {{ data.modelB|safe }}
}

Answer №2

If you're looking to utilize the functionality of the `json` module, one approach could involve:

import json

data = {
        'model1': json.loads(serializers.serialize('json', model1.objects.all())),
        'model2': json.loads(serializers.serialize('json', model2.objects.all())),
       }
context = {'data': json.dumps(data)}

After that, simply use var data = {{data|safe}}
