Currently, I am working on a DFR project where can successfully get all data but i need some modify with the json data.
Here Is the code
class PermissionSerializers(serializers.ModelSerializer):
class Meta:
model = Permission
fields = ['id', 'name', 'codename']
def to_representation(self, instance):
return {
'model': instance.content_type.name,
'data' :{
'id': instance.id,
'name': instance.name,
'codename': instance.codename,
}
}
And i get this JSON format,
{
"next": "http://127.0.0.1:8000/en/ga/api-version/common/admin/permissions/?page=4",
"previous": "http://127.0.0.1:8000/en/ga/api-version/common/admin/permissions/?page=2",
"total": 33,
"page": 3,
"page_size": 10,
"results": [
{
"model": "user",
"data": {
"id": 25,
"name": "Can add user",
"codename": "add_user"
}
},
{
"model": "user",
"data": {
"id": 29,
"name": "Admistrative Access",
"codename": "admin_access"
}
},
But I want to modify with something like this which has model name on top and then all available data inside a dictionary:
{
"model": "user",
"data": {
"id": 26,
"name": "Can change user",
"codename": "change_user"
},
{
"id": 25,
"name": "Can add user",
"codename": "add_user"
},
},
I came up with this solution:
def list(self, request):
_models_list = [
'organization','user','group', 'logentry', 'organizationtype',
'keyword', 'productsupport','feedbacksupport','twittercredential']
models = ContentType.objects.filter(model__in = _models_list)
model_dict = {
'model': '',
'data':''
}
results = []
for model in models:
_permissions = []
access = ' Access'
if model.model == 'group':
model_dict['model'] = 'Role'+ access
elif model.model == 'organizationtype':
model_dict['model'] = 'Organization Type'+ access
elif model.model == 'productsupport':
model_dict['model'] = 'Product'+ access
elif model.model == 'feedbacksupport':
model_dict['model'] = 'Feedback'+ access
else:
model_dict['model'] = model.model.capitalize()+ access
permissions = Permission.objects.filter(content_type = model)
for premission in permissions:
_permissions.append(premission)
serializer = PermissionSerializers(_permissions, many=True)
data = serializer.data
model_dict['data'] = data
results.append(model_dict.copy())
return Response(results)
