I have the following JSON file named ProcessedMetrics.json which is
necessary read for send their values to some template:
{
"paciente": {
"id": 1234,
"nombre": "Pablo Andrés Agudelo Marenco",
"sesion": {
"id": 12345,
"juego": [
{
"nombre": "bonzo",
"nivel": [
{
"id": 1234,
"nombre": "caida libre",
"segmento": [
{
"id": 12345,
"nombre": "Hombro",
"movimiento": [
{
"id": 1234,
"nombre": "flexion",
"metricas": [
{
"min": 12,
"max": 34,
"media": 23,
"moda": 20
}
]
}
]
}
],
"___léeme___": "El array 'iteraciones' contiene las vitorias o
derrotas con el tiempo en segundos de cada iteración",
"iteraciones": [
{
"victoria": true,
"tiempo": 120
},
{
"victoria": false,
"tiempo": 232
}
]
}
]
}
]
}
}}
Through of the following class based view I am reading a JSON file:
class RehabilitationSessionDetail(LoginRequiredMixin,DetailView):
model = RehabilitationSession
template_name = 'rehabilitationsession_detail.html'
def get_context_data(self, **kwargs):
context=super(RehabilitationSessionDetail,
self).get_context_data(**kwargs)
is_auth=False
user = self.request.user
if user.is_authenticated():
is_auth=True
with open('ProcessedMetrics.json') as data_file:
session_data=json.loads(data_file.read())
#Sending a data to template
context.update({'is_auth':is_auth,
'session_data':session_data
})
return context
In my template rehabilitationsession_detail.html I put my tag of this way:
<td>{{session_data.paciente.sesion.juego}}</td>
Then I get the document json in my template:
<http://i.stack.imgur.com/SLZB2.png>
In my template, I want get the dictionary(before json document) values of a
separate way such as follow:
<http://i.stack.imgur.com/MsyHT.png>
The idea is that without matter the nested levels of the json document I
can get the values.
Sometimes, the json document will have more identation levels in their
structure and other times will be a json document more simple
I would that independently of the json document size (if this have more
than one item in your arrays) will be possible read and get all the values.
I try accessing to the specific item from the RehabilitationSessionDetail view
of this way:
segment =
data["paciente"]["sesion"]["juego"][0]["nivel"][0]["segmento"][0]["nombre"]
And this works, but not always I will get the same json document structure.
In summary, How to can I get the values (nested and parents) of my json
document for send them to the template?
I hope can be clear in my question. Any orientation is highly graceful
