Django - Updating multiple models from a form - Data does not saved

[Bernardo Garcia]

I have a custom User model to manage some profiles user: is_student, 
is_professor and is_executive


In this model, in addition, I have the get_student_profile(),
get_professor_profile() andget_executive_profile() methods to get the user 
profiles data of each user from my different views.


class User(AbstractBaseUser, PermissionsMixin):

email = models.EmailField(unique=True)
username = models.CharField(max_length=40, unique=True)
slug = models.SlugField(max_length=100, blank=True)
is_student = models.BooleanField(default=False)
is_professor = models.BooleanField(default=False)
is_executive = models.BooleanField(default=False)

def get_student_profile(self):
student_profile = None
if hasattr(self, 'studentprofile'):
student_profile = self.studentprofile
return student_profile

def get_professor_profile(self):
professor_profile = None
if hasattr(self, 'professorprofile'):
professor_profile = self.professorprofile
return professor_profile

def get_executive_profile(self):
executive_profile = None
if hasattr(self, 'executiveprofile'):
executive_profile = self.executiveprofile
return executive_profile


In addition each profile user is_student, is_professor and is_executive have 
their own model in where I manage their own data:



class StudentProfile(models.Model):
user = models.OneToOneField(settings.AUTH_USER_MODEL, 
on_delete=models.CASCADE)

slug = models.SlugField(max_length=100,blank=True)
origin_education_school = models.CharField(max_length=128)
current_education_school = models.CharField(max_length=128)
extra_occupation = models.CharField(max_length=128)
class ProfessorProfile(models.Model):
user = models.OneToOneField(settings.AUTH_USER_MODEL, 
on_delete=models.CASCADE)
slug = models.SlugField(max_length=100,blank=True)

class ExecutiveProfile(models.Model):
user = 
models.OneToOneField(settings.AUTH_USER_MODEL,on_delete=models.CASCADE)
slug = models.SlugField(max_length=100,blank=True)


Is of this way that in my User model I override the save() method to denote 
that the usernamefield of an user which is created, to be equal in their 
value to the slug belonging to the profile user which will take that user (
StudentProfile, ProfessorProfile, ExecutiveProfile):



def save(self, *args, **kwargs):
user = super(User,self).save(*args,**kwargs)

# Creating an user with student, professor and executive profiles
if self.is_student and not 
StudentProfile.objects.filter(user=self).exists() \
and self.is_professor and not 
ProfessorProfile.objects.filter(user=self).exists() \
and self.is_executive and not 
ExecutiveProfile.objects.filter(user=self).exists():
student_profile = StudentProfile(user=self)
student_slug = self.username
student_profile.slug = student_slug

professor_profile = ProfessorProfile(user=self)
professor_slug = self.username
professor_profile.slug = professor_slug

executive_profile = ExecutiveProfile(user=self)
executive_slug = self.username
executive_profile.slug = executive_slug

student_profile.save()
professor_profile.save()
executive_profile.save()
# And so for all possibles profile combinations


To these three profiles which I have three forms in where their own fields 
are generated


class StudentProfileForm(forms.ModelForm):
class Meta:
model = StudentProfile
fields = ('origin_education_school', 'current_education_school',
'extra_occupation')
class ProfessorProfileForm(forms.ModelForm):
class Meta:
model = ProfessorProfile
fields = ('occupation',)
class ExecutiveProfileForm(forms.ModelForm):
class Meta:
model = ExecutiveProfile
fields = ('occupation', 'enterprise_name', 
'culturals_arthistic','ecological')



I access to view profile to user through of this URL:


url(r"^profile/(?P[\w\-]+)/$",
views.account_profiles__update_view,
name='profile'
),


In my function based view account_profiles__update_view() I am managing the 
request of the user, and creating the form instances (StudentProfileForm, 
ProfessorProfileForm, ExecutiveProfileForm) according to the profile to 
user (is_student, is_professor and is_executive)



@login_requireddef account_profiles__update_view(request, slug):
user = request.user
# user = get_object_or_404(User, username = slug)

# empty list
_forms = []
if user.is_student:
profile = user.get_student_profile()
_forms.append(forms.StudentProfileForm)
if user.is_professor:
profile = user.get_professor_profile()
_forms.append(forms.ProfessorProfileForm)
if user.is_executive:
profile = user.get_executive_profile()

Binding data to one o many forms from one view - BadHeaderError at - Header values can't contain newlines ()

[Bernardo Garcia]

I have the following forms to each user profile

class UserUpdateForm(forms.ModelForm):
class Meta:
widgets = {'gender':forms.RadioSelect,}
fields = ("username", "email", "is_student",   
"is_professor", "is_executive",)
model = get_user_model() #My model User

class StudentProfileForm(forms.ModelForm):
class Meta:
model = StudentProfile
fields = ('origin_education_school',current_education_school',
'extra_occupation')

class ProfessorProfileForm(forms.ModelForm):
class Meta:
model = ProfessorProfile
fields = ('occupation',)

class ExecutiveProfileForm(forms.ModelForm):
class Meta:
model = ExecutiveProfile
fields = ('occupation', 'enterprise_name', 
'culturals_arthistic','ecological')

I have an URL which call to my AccountProfilesView class based view which 
create an instance of the previous forms according to the user profile:

url(r"^profile/(?P[\w\-]+)/$",
views.AccountProfilesView.as_view(),
name='profile'
),


My AccountProfilesView  is this:

I this moment, from the AccountProfilesView class based view I am create 
the different instances of each one of these forms, according to the 
user profile, then, if an user have the is_student profile their related 
form will be generated, and so, of this way to is_professor  and 
is_executive profiles

If an user have the three profiles (is_student, is_professor,is_executive ) 
in one single form will be created or rendered the fields of the three 
forms associated to each user profile related.

class AccountProfilesView(LoginRequiredMixin, UpdateView):
# All users can access this view
model = get_user_model()
#success_url = reverse_lazy('dashboard')
template_name = 'accounts/profile_form.html'
fields = '__all__'

def get_context_data(self, **kwargs):
context = super(AccountProfilesView, 
self).get_context_data(**kwargs)
user = self.request.user

if not self.request.POST:
if user.is_student:
profile = user.get_student_profile()
context['userprofile'] = profile
context['form_student'] = forms.StudentProfileForm()
if user.is_professor:
profile = user.get_professor_profile()
context['userprofile'] = profile
context['form_professor'] = forms.ProfessorProfileForm()
print ("profesor form is", context['form_professor'])
if user.is_executive:
profile = user.get_executive_profile()
context['userprofile'] = profile
context['form_executive'] = forms.ExecutiveProfileForm()
return context

def post(self, request, *args, **kwargs):
self.object = self.get_object()
context = super(AccountProfilesView, self).post(request, *args, 
**kwargs)
user = self.request.user
# if self.request.method == 'POST':
if user.is_student:
context['form_student'] = forms.StudentProfileForm(
self.request.POST)
elif user.is_professor:
context['form_professor'] = forms.ProfessorProfileForm(
self.request.POST)
elif user.is_executive:
context['form_executive'] = forms.ExecutiveProfileForm(
self.request.POST)
return context

def form_valid(self, form):
context = self.get_context_data(form=form)
user = self.request.user
user = form.save()
if user.is_student:
student = context['form_student'].save(commit=False)
student.user = user
student.save()
if user.is_professor:
professor = context['form_professor'].save(commit=False)
professor.user = user
professor.save()
if user.is_executive:
executive = context['form_executive'].save(commit=False)
executive.user = user
executive.save()
return super(AccountProfilesView, self).form_valid(form)

def get_success_url(self):
return reverse('dashboard')

 And in my template, I have the following small logic:


{% csrf_token %}
{% if userprofile.user.is_student %}

My Student Profile data
{% bootstrap_form form_student %}
{% endif %}
 

{% if userprofile.user.is_professor %}
My Professor Profile data
{% bootstrap_form form_professor %}
{% endif %}

   

Accessing to objects of a dynamic way in django template

[Bernardo Garcia]

I have the following class based view in which I perform to queryset:

class PatientDetail(LoginRequiredMixin, DetailView): 

   model = PatientProfile 

   template_name = 'patient_detail.html' 

   context_object_name = 'patientdetail' 

   

   def get_context_data(self, **kwargs): 

   context=super(PatientDetail, self).get_context_data(**kwargs) 
   *queryset= 
RehabilitationSession.objects.filter(patient__slug=self.kwargs['slug']) 
*
* context.update({'patient_session_data': queryset,}) *
return context

When I acces the value of patient_session_data key sent, in my template:

{% extends "base.html" %} 

{% block content %} 

{{patient_session_data}} 
{% endblock content %}

I get this three QuerySet objects

, 
, ]>


I want access to specific attibute named upper_extremity of my 
RehabilitationSession model, then I make this:


{% for upperlimb in patient_session_data %} 

{{upperlimb.upper_extremity}} 

{%endfor%}

And I get this in my template:

Izquierda Izquierda Izquierda

This mean, three times the value, because my queryset return me three 
objects. This is logic.

For access to value of a separate way I make this in my template:

{{patient_session_data.0.upper_extremity}}

And I get:

Izquierda


*My goal*

I unknown the amount of querysets objects RehabilitationSession that will 
be returned by the queryset executed in my PatientDetail

 cbv, because the number is dynamic, may be any amount of objects returned.


I want read the value content of each patient_session_data upper_extremity and 
accord to the value make something in my template,

But I want read it of a dynamic way,without use {{
patient_session_data.<0-1-2-3>.upper_extremity}}


For example in a hypotetical case:


#if all objects returned have same value in upper_extremity 

{% if patient_session_data.upper_extremity == 'Izquierda' %} 

 

  Segmentos corporales a tratar

  Codo - mano - falange 

 

{%endif%}



I think that I have count the amount of objects and make with them some 
actions, because I don't have clear ... 


How to can I access of a individual way to the objects returned of a 
dynamic way without matter the objects number returned?

How to read the json file of a dinamical way in relation to their size structure

[Bernardo Garcia]

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:




In my template, I want get the dictionary(before json document) values of a 
separate way such as follow:










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

When you talk about of optgroup you mean the choicegroup?
In affirmative case, this can be that you looking

Also is possible that MultipleSelectField can be useful for you?
In affirmative case, this thread can be useful...

Deploy static assets to heroku from local machine - can't open file 'manage.py': [Errno 2] No such file or directory

[Bernardo Garcia]

I am trying deploy my assets files to heroku and I get this output in my 
command line interface:

(nrb_dev) ➜  neurorehabilitation_projects git:(master) ✗ heroku run python 
manage.py collectstaticRunning python manage.py collectstatic on

It's strange for me, due to I am currently in the directory/folder in which 
the manage.py file is located

I've applied chmod +x manage.py and try again and this is the output again:

You should install it of this way

1. Download the tar.gz file from 
https://pypi.python.org/pypi/django-multiselectfield
2. Inside of your virtual environment execute pip install 

3. Specify 'multiselectfield' in the INSTALLED_APPS in settings.py

view this 
source 
http://stackoverflow.com/questions/27332850/django-multiselectfield-cant-install

When you run the Django Server, if you are using Django 1.9.2 you see this 
warning 

site-packages/multiselectfield/db/fields.py:45: RemovedInDjango110Warning: 
SubfieldBase has been deprecated. Use Field.from_db_value instead.
  return metaclass(cls.__name__, cls.__bases__, orig_vars)

THis warning is related with this, but I unknown how to fix for the context 
of multiselectfield package application.


Another alternatives for multiselects fields are:
https://github.com/PragmaticMates/django-clever-selects
https://github.com/theatlantic/django-select2-forms
https://github.com/kelvinwong-ca/django-select-multiple-field
https://github.com/digi604/django-smart-selects which I am also using it! 
this works models based in ManyToMany relationships.

I hope that these resource are useful for you.

Best Regards.

django-smart-selects: ChainedManyToManyField value not selected after saving data via django admin

[Bernardo Garcia]

I am working with django-smart-selects 
 via django admin form. 
The idea that I have is try a model chaining or deployment of value fields 
accord to previous value in a previous separate field.


Accord to the first option value selected in the first field, I want that 
in the second field some values be deployed and which be of selection 
multiple. In fact, this idea I got it accomplished.


I have the following small level design approach for this:






The code that is related to the above design is this:

class AffectedSegment(models.Model):
SEGMENTO_ESCAPULA = 'ESCAPULA'
SEGMENTO_HOMBRO = 'HOMBRO'
SEGMENTO_CODO = 'CODO'
SEGMENTO_ANTEBRAZO = 'ANTEBRAZO'
SEGMENTO_CARPO_MUNECA = 'CARPO_MUNECA'
SEGMENTO_MANO = 'MANO'
SEGMENTO_CHOICES = (
(SEGMENTO_ESCAPULA, u'Escápula'),
(SEGMENTO_HOMBRO, u'Hombro'),
(SEGMENTO_CODO, u'Codo'),
(SEGMENTO_ANTEBRAZO, u'Antebrazo'),
(SEGMENTO_CARPO_MUNECA, u'Carpo/Muñeca'),
(SEGMENTO_MANO, u'Mano'),
)
affected_segment = models.CharField(
   max_length=12, 
   choices=SEGMENTO_CHOICES, 
   blank=False, verbose_name='Segmento afectado'
   )

class Meta:
verbose_name = 'Segmentos corporale'

def __str__(self):
return "%s" % self.affected_segment
class Movement(models.Model):
type = models.CharField(
  max_length=255,
  verbose_name='Tipo de movimiento'
  )
corporal_segment_associated = models.ManyToManyField(
  AffectedSegment, blank=False, 
  verbose_name='Segmento corporal asociado'
  )

class Meta:
verbose_name = 'Movimiento'

def __str__(self):
return "%s" % self.type
class RehabilitationSession(models.Model):
affected_segment = models.ManyToManyField(
  AffectedSegment,
  verbose_name='Segmento afectado'
  )
movement = ChainedManyToManyField(
  Movement, #chaining model
  chained_field = 'affected_segment',
  chained_model_field = 'corporal_segment_associated',
  verbose_name='Movimiento')



Until this section all this O.K.

*MY CHALLENGES*


*1. *When I save one movement (model Movement chained) which are related to 
affected segment (affected_segment in AffectedSegment model and 
ManyToManyField in RehabilitationSession model) , after I going to this row 
or rehabilitation sessions instance via admin and the movement that I 
select before is not selected, despite of that this is saved and I can 
explore via transitivity relationship the value inside my postgresql 
database.



In this video , I've been exploring the 
database records and showing the behavior of my form in which is denoted my 
inconvenient

I can see that this bug/error/issue or inconvenient was happen to 
others https://github.com/digi604/django-smart-selects/issues/112


*2.* Other inconvenient is that when I select more of than one affected 
segment, in the movements field. just are deployed the values related with 
the first affected segment selected and the movements associated to the 
second selected are not deployed ...

The explanation is the following accord to this picture:




When I select one second affected segment (segmento afectado field, *CODO* 
option 
in the red square number one), I want that the movements/exercises 
associated to these second affected segment that it's *CODO*


Currently, just are deployed the movements of Descenso,Elevación, 
Protracción y Retracción (options shown in the green square number two) and 
these are only or correspond to the first option of affected segment 
selected which is ESCÁPULA in the red square number one


In this video  I show you this in detail.


How I can do this I want?


In some sense, in the AffectedSegment model .. should be able to know the 
option (something seem to get_element_by_id in html?) is selected for know 
when one second option is selected and shown the movements of together 
options (affected segments selected)?


I hope that post a videos don't be a problem or inconvenient


Any support or orientation would be appreciated

Re: API REST - Url's Serialized models don't work with the hostname of my production server - Django Rest Framework

[Bernardo Garcia]

Hi James. 
Thanks for your attention and the stackoverflow reference

I try setup the headers in my nginx configuration file but I don't get 
success

My /etc/nginx/sites-enabled/myproject file I had so:

server {
server_name yourdomainorip.com;
access_log off;
location / {
proxy_pass http://127.0.0.1:8000;
proxy_set_header X-Forwarded-Host $server_name
proxy_set_header X-Real-IP $remote_addr;
add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM 
NAV"';
}
}


According to the 
reference 
http://stackoverflow.com/questions/19669376/django-rest-framework-absolute-urls-with-nginx-always-return-127-0-0-1
 
my /etc/nginx/sites-enabled/myproject file I stayed so:

server {
server_name yourdomainorip.com;
access_log off;
location / {
proxy_pass http://127.0.0.1:8000;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM 
NAV"';
}
}

But, the result was a bad request (400) how to you can see here 
http://ec2-52-90-253-22.compute-1.amazonaws.com/ 

What is the order in which I should setup the headers?
Thanks

Felipe, give me a couple of minutes and I tell to you, but If you see my 
first post in this thread, the api links is related with the serializers.py 
file, in the urls.py files the router.register sentence and the views.py 
the ViewSet class

In this post   is detailed

Re: API REST - Url's Serialized models don't work with the hostname of my production server - Django Rest Framework

[Bernardo Garcia]

Avraham, so yes, efectively ...

This is my gunicorn_config.py

command = '/opt/uleague/bin/gunicorn'
pythonpath = '/opt/uleague/pickapp'
bind = '127.0.0.1:8000'
workers = 3


I will should in the directive bind put the  internal ip address of my 
machine?
I have some doubts


   - The internal ip address of my machine is 172.31.60.141
   

root@ip-172-31-60-141:/etc/nginx/sites-enabled# ifconfig 
eth0  Link encap:Ethernet  HWaddr 12:73:40:a8:59:99

root@ip-172-31-60-141:/etc/nginx/sites-enabled# 

But in my dashboard console, the dns public of my ec2 instance is:
ec2-52-90-253-22.compute-1.amazonaws.com, in fact, you can copy this url in 
a browser...

I don't know that value of address put in my gunicorn_config.py in the 
directive bind.
I put the internal ip address but does not work my server deployment

And my nginx configuration is the following:

/etc/nginx/sites-enabled/myproject , in which I unknown if in the 
server_name and proxy_pass directives I should fix some values too..
server {
*server_name yourdomainorip.com;*
access_log off;
location / {
*proxy_pass http://127.0.0.1:8000;*
proxy_set_header X-Forwarded-Host $server_name;
proxy_set_header X-Real-IP $remote_addr;
add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM 
NAV"';
}
}

API REST - Url's Serialized models don't work with the hostname of my production server - Django Rest Framework

[Bernardo Garcia]

Hi everyone Djangonauts
:)

Currently I am exposing a Django application (for the momento is just thier 
users schema) with Django Rest Framework and happen that each serialized 
model, in the url attribute, I have is the localhost machine address 
development and don't take the hostname of my production server machine 
which is located in amazon like as EC2 instance


In this picture can detailed it.






How to make for the url of each model that I've serialized take the 
hostname of the production machine in which the application is deployed? In 
this case, an amazon ec2 instance ...


These are my serialized models userprofiles/serializers.py 


from django.contrib.auth.models import Groupfrom .models import User, 
PlayerProfile, CoachProfile, ViewerProfilefrom rest_framework import serializers
# Serializers define the API representation# Exponse the model and their 
fieldsclass UserSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = User
fields = ('url','id', 'username', 
'password','first_name','last_name','email','is_active',
  
'is_staff','is_superuser','last_login','date_joined','is_player','is_coach',
  'is_viewer','photo',)
class GroupSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = Group
fields = ('url', 'name')

class PlayerProfileSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = PlayerProfile
fields = ('url', 'user','full_name','position',)
class CoachProfileSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = CoachProfile
fields = ('url', 'user','full_name',)
class ViewerProfileSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = ViewerProfile
fields = ('url', 'user','full_name','specialty')



This is my urls.py global file (not belont to userprofiles application that 
contain all the serialized models.)


from django.conf.urls import url, includefrom django.contrib import admin
from .views import home, home_files
from rest_framework import routersfrom userprofiles import views
# Router provide an easy way of automatically determining the URL conf
router = routers.DefaultRouter()
router.register(r'users', views.UserViewSet)
router.register(r'groups', views.GroupViewSet)
router.register(r'players', views.PlayerProfileViewSet)
router.register(r'coachs', views.CoachProfileViewSet)
router.register(r'views', views.ViewerProfileViewSet)


urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^$', home, name='home'),

url(r'^(?P(robots.txt)|(humans.txt))$',
home_files, name='home-files'),

# Wire up our API using automatic URL routing.
url(r'^api/v1/', include(router.urls)),

# If you're intending to use the browsable API you'll probably also want to 
add REST framework's
# login and logout views.
url(r'^api-auth/', include('rest_framework.urls', 
namespace='rest_framework'))] 



And this is my userprofiles/views.py file in where I have expose the models 
serializeds


from django.shortcuts import renderfrom django.contrib.auth.models import 
Groupfrom .models import User, PlayerProfile, CoachProfile, ViewerProfile
from rest_framework import viewsetsfrom .serializers import UserSerializer, 
GroupSerializer, PlayerProfileSerializer, CoachProfileSerializer, 
ViewerProfileSerializer
# Create your views here.
# Viewsets define the behavior of the viewclass 
UserViewSet(viewsets.ModelViewSet):
"""
API endpoint that allows users to be viewed or edited.
"""
queryset = User.objects.all().order_by('-date_joined')
serializer_class = UserSerializer
class GroupViewSet(viewsets.ModelViewSet):
"""
API endpoint that allows groups to be viewed or edited.
"""
queryset = Group.objects.all()
serializer_class = GroupSerializer
class PlayerProfileViewSet(viewsets.ModelViewSet):
"""
API endpoint that allows players to be viewed or edited.
"""
queryset = PlayerProfile.objects.all()
serializer_class = PlayerProfileSerializer
class CoachProfileViewSet(viewsets.ModelViewSet):
"""
API endpoint that allows coachs to be viewed or edited.
"""
queryset = CoachProfile.objects.all()
serializer_class = CoachProfileSerializer
class ViewerProfileViewSet(viewsets.ModelViewSet):
"""
API endpoint that allows viewers to be viewed or edited.
"""
queryset = ViewerProfile.objects.all()
serializer_class = ViewerProfileSerializer


Any orientation or support about it, I will be grateful :)

Re: Amazon + Django each 12 hours appears that [Errno 5] Input/output error

[Bernardo Garcia]

Hi, luisza14

You have the reason, I had my project in DEBUG=True in production, and the 
main problem was a print sentence in some of my CBV's in the code in 
production
Here, recently I can write how to fix 
this 
http://stackoverflow.com/questions/34643170/amazon-django-each-12-hours-appears-that-errno-5-input-output-error/34667148#34667148
using also the reference that you provide me.

Thanks so much
:)

In addition I had this error yesterday, I restart my server, and today I

There is some problem with EC2 infraestructure with Django (I don't think 
so) or the problem is more for my application side?

I don't think so that the function get_context_data() of my application be 
the problem ...

Of this way, is possible create an user which have all the combinations 
possible (medical, physiotherapist, patient)

Thanks for the recommendations :)

Amazon + Django each 12 hours appears that [Errno 5] Input/output error

[Bernardo Garcia]

I recently setup and deploy an Amazon EC2 instance for deploy my django 
project.

I  was interacting with my application via browser when I get this error in 
the browser:


errno 5 input/output error django 


This error did reference to some function of my application, but in my 
console the server require restart and when I did this, the error was 
solved of a magic way ..


I've search this error and I found this ticket 
reported https://code.djangoproject.com/ticket/23284


This report is very similar to my error ...

Although I don't know if this error back inside 12 hours, I restart my 
server and this was solved and now all it's work O.K.



When one bug is declared as invalid in Django 


What does it mean? 


There is some problem with EC2 infraestructure with Django (I don't think 
so) or the problem is more for my application side?


Thanks

Working with Django signals

[Bernardo Garcia]

I have a custom users schema in Django for work with roles or users type, 
creating an application named userprofile which will be or will setup my 
custom user model.

In my settings.py I have the following configuration:

INSTALLED_APPS = [
...
'userprofile',]#Custom model Users
AUTH_USER_MODEL = 'userprofile.User'


I customize my User class (userprofile/models.py) that inherit of the 
AbstractUser class for add some fields to my User model due to my 
requirements demanded me.

I also create these another models for roles/profile users (MedicalProfile, 
PatientProfile, PhysiotherapistProfile) with their own fields or attributes


In addition MedicalProfile, PatientProfile, PhysiotherapistProfile have a 
OneToOneField relationship with my custom model/class User so:

So we’re defined a signal for the User model, that is triggered every time a

This signal checks if a new instance of the User model has been created,

*My Question*

I want to focus my question in relation about of the post_save signal 
operation, this mean in the create_profile_for_new_user() method:


@receiver(post_save, sender=settings.AUTH_USER_MODEL)def 
create_profile_for_new_user(sender, instance, created, **kwargs):
user = instance
# - Begin debug--
import ipdb
#
if created:
if user.is_medical:
ipdb.set_trace()
