Re: Updating FK values for Stock Application

[Shazia Nusrat]

All I was asking to make FK editable. I can do it in views by making forms 
from "forms.Form" in Django and update models I needed to update.

Just thought that there might be a simpler way where I can choose an option 
from ManyToMany select box and then edit those values.

Updating FK values for Stock Application

[Shazia Nusrat]

Hi, 
I am developing a stock management application and I am stuck at simple use 
case.

Following is my model for Stock:

class LiquidChemicalML(Stock):
supplier_name = models.ManyToManyField(Supplier)
quantity_values = (
('Ounces', 'Ounces'),
('Millilitters', 'Millilitters'),
('Pounds', 'Pounds'),
('Liter', 'Liter'),
('Galon', 'Galon'),
('Kilogram', 'Kilogram'),
('Grams', 'Grams')
)
chemical_name = models.CharField(max_length=200)
chemical_quantity = models.IntegerField()
unit_of_measurement = models.CharField(max_length=20, 
choices=quantity_values)
purchase_date = models.DateField()
expiry_date = models.DateField()class LiquidChemicalML(Stock):
supplier_name = models.ManyToManyField(Supplier)
quantity_values = (
('Ounces', 'Ounces'),
('Millilitters', 'Millilitters'),
('Pounds', 'Pounds'),
('Liter', 'Liter'),
('Galon', 'Galon'),
('Kilogram', 'Kilogram'),
('Grams', 'Grams')
)
chemical_name = models.CharField(max_length=200)
chemical_quantity = models.IntegerField()
unit_of_measurement = models.CharField(max_length=20, 
choices=quantity_values)
purchase_date = models.DateField()

I need to update my orders model with available quantity and literals. My 
Orders are:

class Orders(models.Model):
 update_chemical = models.ForeignKey(…..

I just need your help to give me idea that how I can update my orders with 
multiple fields from Stock. For instance if I create a foreignkey I will 
only be able to select one of the "id" in available stocks. I need to let 
the user select or update multiple values in a FK based key. Please advise. 

Best Regards,
Shazia

Re: How can I host my django project on my pc for someone to see it outside my WIFI network

[Shazia Nusrat]

You also need to add your url provided by Ngrok to your Django settings.py 
"ALLOWED_HOSTS". Only then it will present your site on that URL.

Re: How can I host my django project on my pc for someone to see it outside my WIFI network

[Shazia Nusrat]

Ngrok will help you publish your site for development if you need to show 
your work remotely. Remember you need to run two terminals on terminal 1 
you will run your project as you normally do and on other terminal you need 
to run ngrok. It will provide you with couple of URLs one for http and 
another for https. Https is usually if you need to test it with social 
authentication etc. 

Hope this helps.

Re: Django - CreateView not saving form with nested formset

Hi,

Tried all suggestions above and nothing worked out.
To my surprise I heard Python/Django community is more robust and helping

Re: Multiple user roles with permissions

[Shazia Nusrat]

I just needed a working example of added permissions system in a project I
can run.
Django-rules is good and I've tried it in my test-project. I was hoping a
project with bunch of user types and assigned permissions hardcoded.
I know I can do things from default admin dashboard.

How to populate DB from PDF extracted data

[Shazia Nusrat]

Hi,

I am trying to work around with PDF's where user uploads PDF in image or
filefield and then way to extract it for Django and finally update DB table
based on it. Following are the models:

class StudentFee(models.Model):
   class_name = models.CharField(choices=CLASSES, max_lenght=200)
   fee_deposit_slip = models.ImageField(upload_to="students/")

   def __unicode__(self):
 return unicode(self.class_name)

All I need is to design a view where I can extract data from the PDF
uploaded in the model below:

class StudentInfo(models.Model):
first_name = models.CharField(max_length=200)
last_name = models.CharField(max_length=200)
email=models.EmailField()
phone = PhoneField() #using phoneField custom field
def __unicode__(self):
   return unicode(self.first_name)

All the fields in second model does exist in the PDF. In my Views.py

class StudentPDFReader(FormView):
  template_name = 'pdfdata.html'
  form_class = PDFForm
  success_url = '/success/'

  def form_valid(self, form):
   # here I need to extract and add entries to modelform
  return super(StudentPDFReader, self).form_valid(form)

Looking for kind help.

Shazia

GIS Address Form Creation

[Shazia Nusrat]

 Hi,

I am trying to create a simple location form from GIS models and following
GeoDjango tutorial and after completing the tutorial I am still confused
about how to go for it.

What I need is that users come in on my page and they select their location
from the map and it should save in the database. So I am looking for
ModelForm based form so I can save it. I tried to use Django-Map-Widgets
and found that it does not support python 3.


Your assistance is appreciated.

Shazia

Creating Forms from frontend like Google Survey Forms

[Shazia Nusrat]

Hi,

I need to develop a view that can help end-users create forms from the
frontend like SurveyMonkey or Google Survey Forms. Basically I need to get
admin forms at frontend and let the user's create forms on given set of
fields.

Can anyone point me to right direction please?

Thanks.
Shazia

Dynamic Model ID cannot be called

[Shazia Nusrat]

Hi,

I have a simple model like below:

class Artists(models.Model):
   name = models.CharField(max_length=200)
   description = models.TextField()

   def __unicode__(self):
 return self.name

I am trying to call it in my view like below:

def artistdetail(request, id):
   artista = Artist.objects.get(id=id # this line is giving me
error.


Can someone explain me how to get the id in operational mode. I can call
IDs with filtering by name in shell. But how to set it up for the user who
uses it.


Regards,
Shazia

Django Forms HorizontalRadioSelect Renderer not working.

[Shazia Nusrat]

Hi,

I need to select form values horizontally but couldn't get it work.

Following is the code:

class HorizontalRadioRenderer(forms.RadioSelect.renderer):
  def render(self):
return mark_safe(u'\n'.join([u'%s\n' % w for w in self]))

class ResponseForm(models.ModelForm):
class Meta:
model = Response
fields = ('interviewer', 'interviewee', 'conditions', 'comments')
def __init__(self, *args, **kwargs):
# expects a survey object to be passed in initially
survey = kwargs.pop('survey')
self.survey = survey
super(ResponseForm, self).__init__(*args, **kwargs)
self.uuid = random_uuid = uuid.uuid4().hex
# add a field for each survey question, corresponding to the
question
# type as appropriate.
data = kwargs.get('data')
for q in survey.questions():
if q.question_type == Question.TEXT:
self.fields["question_%d" % q.pk] =
forms.CharField(label=q.text,
widget=forms.Textarea)
elif q.question_type == Question.RADIO:
question_choices = q.get_choices()
self.fields["question_%d" % q.pk] =
forms.ChoiceField(label=q.text,

widget=forms.RadioSelect(renderer=HorizontalRadioRenderer),
choices = question_choices)

Error:

class HorizontalRadioRenderer(forms.RadioSelect.renderer):
AttributeError: type object 'RadioSelect' has no attribute 'renderer'

Re: Multiple Types of Account with Abstract User

[Shazia Nusrat]

I will try it but I have a question that how can I link this to
Django-regisration-redux app. Like if somebody tries to sign in they should
have registration choices within registration app to save my time.

As I visualize it that I should be able to login as supplier from
registration redux template system as supplier/designer or whatever role as
user I chose.


Thank you for your help and will try and let you know about the update.

Re: Multiple Types of Account with Abstract User

[Shazia Nusrat]

I've deleted DB and migrations I had previously.
But still can't figure this out. What I need isthat multiple shops
needs to get registered with my ecommerce store as well as designers and as
well as referrers to sell products and then simple registration while
checkout is in progress.

I have simple idea that I need to somehow create submodel from built-in
User model with abstract model. Then I want that if user selects Customer
then customer form should appear, if user says Designer it should present
designer and so on except the checkout user that I figured out to complete
the order with guest user by catching session ID and user's email upon
checkout.

This part I can't figure out. Moreover all these account should have access
to relevant content. Like Supplier should be able to manage inventory or
his/her products. Designer only should sell their products in bulk etc. So
if I fix this issue then I can move forward otherwise its a dead lock for
me from 4 last hours.

Multiple Types of Account with Abstract User

[Shazia Nusrat]

Hi,
I am trying to create multiple types of users in my django e-commerce
project by extending built-in Django user model but I am having issue.

Would appreciate if someone can guide me to right direction.
Following is the code in my "accounts" app.

from __future__ import unicode_literals
from django.db import models
from django.contrib.auth.models import AbstractUser

class CustomUser(AbstractUser):
type_choices = (
('Supplier', 'Supplier'),
('Designer', 'Designer'),
('Shop', 'Shop'),
('Referrer', 'Referrer'),
('User', 'User'),
)
user_type = models.CharField(max_length=2,
 choices=type_choices,
 default='User')

class UserDetails(models.Model):
type = models.OneToOneField(CustomUser)
extra_info = models.CharField(max_length=200)

My settings.py includes 'accounts' in installed app and variable included
for extending models in settings.py:

AUTH_USER_MODEL = 'accounts.Customer'

Error:


ERRORS:
accounts.CustomUser.groups: (fields.E304) Reverse accessor for
'CustomUser.group
s' clashes with reverse accessor for 'User.groups'.
HINT: Add or change a related_name argument to the definition for
'Custo
mUser.groups' or 'User.groups'.
accounts.CustomUser.user_permissions: (fields.E304) Reverse accessor for

User.user_permissions' clashes with reverse accessor for
'User.user_permissions'
.
HINT: Add or change a related_name argument to the definition for
'Custo
mUser.user_permissions' or 'User.user_permissions'.
auth.User.groups: (fields.E304) Reverse accessor for 'User.groups' clashes

reverse accessor for 'CustomUser.groups'.
HINT: Add or change a related_name argument to the definition for
'User.
groups' or 'CustomUser.groups'.
auth.User.user_permissions: (fields.E304) Reverse accessor for
'User.user_permis
sions' clashes with reverse accessor for 'CustomUser.user_permissions'.
HINT: Add or change a related_name argument to the definition for
'User.
user_permissions' or 'CustomUser.user_permissions'.

Please advise.

Shazia

[Kind Attention Requested] Django Zinnia blog error for entries

[Shazia Nusrat]

I am trying to fix issue with Zinnia blog application and its popping up
error related to aggregator and entries. Following is the code if someone
have a suggestion:

def get_authors(context, template='zinnia/tags/authors.html'):
"""
Return the published authors.
"""
entries = Entry.objects.all()
return {'template': template,
'authors': Author.published.all().annotate(
count_entries_published=Count('entries')),
'context_author': context.get('author')}

Above I don't think causing any issue but below is the code that might be
causing all the fuss in second last line.

def get_queryset(self):
"""
Return a queryset containing published entries.
"""
now = timezone.now()
return super(
EntryRelatedPublishedManager, self).get_queryset().filter(
models.Q(entries__start_publication__lte=now) |
models.Q(entries__start_publication=None),
models.Q(entries__end_publication__gt=now) |
models.Q(entries__end_publication=None),
entries__status=PUBLISHED,
entries__sites=Site.objects.get_current()
).distinct()

Please suggest a solution because overall Zinnia is an impressive app but
with one error its almost useless. Owner of the repo already got plenty of
users with same complain. Error is same with both Python2 and PYthon3.

For generous coders willing to work on this, repo is located at

Re: Error: int() argument must be a string or a number, not 'SimpleLazyObject'

[Shazia Nusrat]

Following is the dispatch function:

 def dispatch(self, request, *args, **kwargs):
try:
user_check_id = self.request.session.get("user_checkout_id")
user_checkout = UserCheckout.objects.get(id=user_check_id)
except UserCheckout.DoesNotExist:
user_checkout = UserCheckout.objects.get(user=request.user)
except:
user_checkout = None

obj = self.get_object()
if obj.user == user_checkout and user_checkout is not None:
return super(OrderDetail, self).dispatch(request, *args,
**kwargs)
else:
raise Http404

On line 27 color is red. Usually the error related to SimpleLazyObject
means that it's not able to grab the field with reference. I don't know
what to replace it with.

Non Admin Dashboard/Shop Login for Suppliers

[Shazia Nusrat]

Hi,

I am using Django-registration for registration process in my django
project. Now I need to add a shop login for resellers. Can some one provide
me the process to add Shop-Dashboard in NLP like in non coding format just
to give me idea how to go for it.

Do I need to build form from my Shop models and then present it in view and
that's it?
Kindly give me benefit out of your experience that what are the
considerations I should work with.

Regards,
Shazia
