Re: JSON file
I am not sure about the field names part, but you could probably create
that manually very easily.
For the data section, you need a list of lists, which you can get from code
like:
import json
data_ready_for_json =
list(mail_item_count_deliveries_perDate.objects.values_list('countDeliveries','Dates'))
json_string = json.dumps(data_ready_for_json)
(P.S. you may want to consider giving your classes more Python-like names
e.g. class MailDelivery )

I ‘m not sure if that is a JSON file because a JSON file is nothing but a python dictionary like structure and that doesn’t seem to be that.

Re: HTML form filled, proposes a download link for the data filled in a json file
Hello!
well in the form is there anything that will be saved in a database?
if so you can start by looking at models.py in your application.
if not you can jump directly to forms.py.
an example of a model and form:
*** in models.py
from django.db import models
class Company(models.Model):
"""This is your database model with the fields you want to store and
fetch!
"""
name = models.CharField(max_length=60)
telephone = models.CharField(max_length=15, null=True, blank=True)
info = models.TextField(blank=True, null=True)
is_awesome = models.BooleanField(default=False)
*** in forms.py
from django import forms
from .models import Company
class CompanyForm(forms.ModelForm):
class Meta:
model = Company
fields = '__all__'
widgets = {
'is_awesome': forms.HiddenInput(),
}
then when you have a form and model you can use the generic views like this:
*** in views.py
from django.urls import reverse_lazy
from django.views.generic import CreateView
from django.contrib.messages.views import SuccessMessageMixin
from .models import Company
from .forms import CompanyForm
class Add_Company(SuccessMessageMixin, CreateView):
template_name = 'company/add_a_new.html'
success_message = 'a new company was added!'
success_url = reverse_lazy('home')
form_class = CompanyForm
thats it!

Yes, I probably should validate the input that way, but what I'm concerned with at the moment is how the JSON details make it to the form object in the first place. I probably got overwhelmed reading the API Docs and thought there has to be a more elegant way to handle the JSON -> Form Object part than just writing a ``post`` method. > > On another note, there are several Models I want to work with in > > this way so it would be even better if I could select the model > > class according to the contents of the json file. > > > > This sounds like a validation job to me.

Filling out a form using a json file
Hi, I have a json file describing an object that I want to import into my app. For that purpose, I want to upload it using a form field and fill a ModelForm so the contents can be checked and edited by a user before saving it to the database. This is what I'm currently doing: # in forms.py class MyObjectRequestForm(forms.ModelForm): """ Form for generating a MyObject from a json file """ class Meta: model = MyObject exclude = () # in views.py class MyObjectFromFile(LoginRequiredMixin, View): def post(self, request): """ generate Form from json in 'message_file' parameter. """ context = dict() received_object = json.load(request.FILES['message_file']) new_my_object = MyObject() new_my_object.derive_from_message(received_object) context['form'] = MyObjectRequestForm(model_to_dict(new_my_object)) return render(request, 'myapp/my_object_form.html', context) I already have a CreateView and UpdateView for this kind of object so I probably should inherit from one of those to take advantage of the ``get_success_url`` method and to avoid writing a completely new view for editing Objects, but it seems that those views can only deal with objects that already are in the database. So is there a more idiomatic way to solve this or am I stuck with the above solution? On another note, there are several Models I want to work with in this way so it would be even better if I could select the model class according to the contents of the json file.

How to read the json file of a dinamical way in relation to their size structure
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:
{{session_data.paciente.sesion.juego}}
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

Creating JSON file
You want to output a list of one dict per object, and you want that dict to
contain another dict inside it. So you don’t need dict2. Instead
f = file('report.json','a+')
sys.stdout = f
result = []
objects = game_objects.objects.all()
for obj in objects:
time = time_stamp.objects.filter(user_id = obj.user_id)
obj_id = obj.object_id
per = performance.objects.filter(user_id = obj.user_id)
pat = pattern.objects.filter(user_id = obj.user_id)
dict1 = {'user_id' : obj.user_id, 'game_id': obj.game_id}
dict1[obj_id]={'color': obj.color, 'speed': obj.speed, 'energy':
obj.energy }
result.append(dict1)
