[Django] A memorandum when you want to communicate asynchronously [Python3]

A memo for getting data from DB with Ajax and returning it in JSON format with Django.

First of all, in order to use Ajax with Django, if it is post, processing like the following page is required. Django Official: https://docs.djangoproject.com/ja/1.10/ref/csrf/

It is necessary to create a js file according to this.

Also, Django has a library for JSON conversion such as JSON response and serialize by default, but since it takes Model data directly and converts it to JSON, it is delicate because unnecessary data such as pk is also sent. So, this time, I thought about using the Python library to define another function for Json conversion for Ajax and control it so that it is skipped by urls.py. EX.

sample/models.py 
class Sample(models.Model):
    name = models.CharField(max_length=30)
    first = models.CharField(max_length=30)
sample / ajax.py (instead of views.py) 
def SampleListAjax(request): 
    objs = Sample.objects.all()
    data = [dict(name = obj.name, first = obj.first) for obj in objs]
    json = json.dumps(data)
    return HttpResponse(json, content_type="application/json")
sample/urls.py 
class urlpatterns=[
    url(r'^sample/',ajax.SampleListAjax)
]

After that, as usual, just request the url set by Ajax with something JavaScript and get the JSON data. If you want to control with HTTP method Obtained with request ["method"]. PUT can be obtained with QueryDict.

Please let me know if there is a better way.
