Can't update existing record in django - python

I need to update existing recode in the database.I'm using mysql.
this my model class
class SuSurey(models.Model):
#id = models.IntegerField(db_column='ID', primary_key=True) # Field name made lowercase.
su_name = models.CharField(db_column='su_Name', max_length=30) # Field name made lowercase.

def __unicode__(self):
return self.su_name
class Meta:
managed = False
db_table = 'su_surey'
i didn't use any forms in my web application. In my view.py i have this
if request.method == 'POST':
date=request.POST.get('dates','').split('-')
survey_data=SuSurey.objects.get(id=survey_id)
survey_data.su_name=request.POST.get('Name','')
survey_data.description=request.POST.get('Description','')
survey_data.duration=request.POST.get('Duration','')
survey_data.audience=request.POST.get('Audience','')
survey_data.start_date=date[0]
survey_data.end_date=date[1]
survey_data.update_date=datetime.datetime.today()
survey_data.update_by=request.session['user_login_data']['id']
try:
survey_data.full_clean()
survey_data.save(update_fields=['su_name','description','duration','audience','start_date','end_date','update_date','update_by'])
messages={'success':'Successfuly data added'}
url = reverse('addQuestionSurveys', kwargs={'survey_id': survey_id })
return HttpResponseRedirect(url)
except ValidationError as e:
messages={'error':e.messages}
return render(request, 'pages/forms/newSurvey.html',{'dept_data': dept_data,'messages': messages},context_instance=RequestContext(request))
when i add data Django did update the recode that is find by survey_id recode. it will add new recode to database.how can i fix this problem ? need a quick help thank you.

How can I add a button inside DetailView template that sends ID to a form?

I have a App called "Properties" and I've created a DetailView that is working. Inside my Properties models I have a Property model and a Bedroom model with a ForeignKey to Property.
#views.py
class PropertyDetailView(DetailView):
template_name = 'properties/property-detail.html'
model = Property
def get_context_data(self, **kwargs):
contacts = ContactsOwner.objects.filter(owner__property=self.object)
context = super().get_context_data(**kwargs)
context['contact'] = contacts
return context
My models.py:
class Property(models.Model):
property_reference = models.CharField(db_column='Property_Reference', max_length=10) # Field name made lowercase.
address = models.CharField(db_column='Address', max_length=250, blank=True, null=True) # Field name made lowercase.
post_code = models.CharField(db_column='Post_Code', max_length=15, blank=True, null=True) # Field name made lowercase.
type = models.CharField(db_column='Type', max_length=25, blank=True, null=True, choices=HOUSE_TYPE_CHOICES) # Field name made lowercase.

class Meta:
db_table = 'Property'
def __str__(self):
return self.property_reference
def get_absolute_url(self):
return reverse("properties:property_detail",kwargs={'pk':self.pk})
class Bedroom(models.Model):
type = models.CharField(db_column='Type', choices=BEDROOM_TYPE_CHOICES, max_length=50)
bed_dimensions = models.CharField(db_column='Bed_Dimension', choices=BED_DIMENSION_CHOICES, max_length=30)

notes = models.CharField(db_column='Notes', max_length=500, blank=True, null=True) # Field name made lowercase.
property = models.ForeignKey(Property, null=False, on_delete=models.CASCADE, related_name='bedroom')
What I need is to create a button named "Add Bedroom" inside the template "property-detail.html" that sends me to a form with pre filled Foreign Key. Could you please help me on this?

You need to redirect that button submit to a view that gets the required info you want and then redirect that to another template with context the info you received (your Foreign key per se)

And then call it by using just
mouvements = ResumeMvtActif.objects.all()
But of course i get a Database error because i don't really have a ResumeMvtActif table.
How can i proceed to make this work ? do i have to create an extra table on my DB ? Is there a trick to tell Django that it's not a real table and just a join of two tables ?

Django Restful Framework - Limit Results Based on Role/Group

I'm trying to build an API in Django Rest Framework (Python 3.x). As a requirement from our b2b partners we can only redistribute their content to certain users. Therefore, I'd like to edit the view to only return certain data based on a users group/role in the system.
For example, I have the following model:

If the user is not in the auth_group 'admin' (id 1) then I'd like to restrict the results so that it shows all results except where user_provider_id in [1,3]. How can I do this?

You should override get_queryset() method to restrict results based on admin auth group.
class LocalDealsViewSet(viewsets.ModelViewSet):
"""
API endpoint that allows local_deals to be viewed.
"""
throttle_classes = (UserRateThrottle,)
serializer_class = LocalDealsSerializer
def get_queryset(self):
# check here if 'list' request and user not in admin auth group
if self.action == 'list' and self.request.user not in admin auth_group:
# exclude results with 'user_provider_id' in [1,3]
return LocalDeals.objects.all().exclude(user_provider_id__in=[1,3])
# Otherwise return all results
return LocalDeals.objects.all()

Thanks for helping.

The radiotipo_idradiotipo is a foreign key to a model called "RadioInfo", but you don't have any model called that: only one called "Radiotipo". Is that the one you meant?

Change:
radiotipo_idradiotipo = models.ForeignKey('Radioinfo', db_column='radioInfo_idRADIOINFO') # Field name made lowercase.
By:
radiotipo_idradiotipo = models.ForeignKey('Radiotipo', db_column='radioInfo_idRADIOINFO') # Field name made lowercase.
Notice that you are using the table_name instead of the Model_Name for the foreingkey

Django filter() returning object instead of contents

Brand new to Django so excuse the newbie question. I cannot for the life of me get a Google search to return what I need.
First, I imported these using inspectdb.
Second, before providing the:
def __unicode__(self):
return u'%s %s' % (self.id, self.cuisine)
in the models, every database showed what looked like bound objects versus the actual data when looking in the admin. I assumed this was normal.
Now I'm trying to query the database and show the results. Just doing something simple, the code is:
def expand(request):
userid = Userid.objects.filter(name__contains="Test")
return render(request,'expand.html',{'userid':userid})
The return should just be Test 1, Test 2, but instead I get:
[<Userid: Userid object>, <Userid: Userid object>]
Tried userid, userid.name in the template and both return the object versus the contents.
Thanks, sorry for what I'm sure is a repeat question!

class Meta:
db_table = 'userID'
Template:
<p>{{ userid }}</p>

You need to parse through the object elements individually.
Like this:
{% for user in userid %}
{{user}}
{% endfor %}
--OR--
{% for user in userid %}
{{user.name}}
{% endfor %}
The __unicode__ attribute is applied only to individual objects, and not a queryset. Hence the issue.
Make sure your __unicode__ is on the Userid model.
If you want to just display the name list, you can alternatively do
def expand(request):
userid = Userid.objects.filter(name__contains="Test").values_list('name', flat=True)
return render(request,'expand.html',{'userid':", ".join(list(userid))})
and your template would be just:
{{userid}}

In your Userid model, add the __unicode__ method:
class Userid(models.Model):
# all your fields
class Meta:
db_table = 'userID'
def __unicode__(self):
return unicode('{0} {1}'.format(self.name, self.id))
