Managing multiple user types in Django

[Frankline]

Hello Everyone,

I am developing an API based on Django Rest Framework
. Currently I have 4 user types i.e.
Buyer, Merchant, Insurer, and Admin.

The system I'm developing has an *API endpoint* and a *Dashboard* view.

Each of the above user types have different fields and may need to login to
the system at one point, so having one user model is the best way to go.
Note that, a user can only be of one type.

However, only the merchant will be actively using the API endpoint.

My question is then, how will I be able to manage the different user types
in the system?

My current options are:

1.

   1. class BaseUser(AbstractBaseUser):
   2. ...
   3.
   4. class Buyer(BaseUser):
   5. ...
   6.


   1. class Merchant(BaseUser):
   2. ...
   3.


   1. class Insurer(BaseUser):
   2. ...


2.


   1. from django.db import models
   2. from django.contrib.auth.models import User
   3.
   4. class Buyer(models.Model):
   5. user = models.OneToOneField(User)
   6.
   7. class Merchant(models.Model):
   8. user = models.OneToOneField(User)
   9.


   1. class Insurer(models.Model):
   2. user = models.OneToOneField(User)



   1. ...


Which is the most optimal way of handling this?

How to create a custom widget using django for use on external sites

[Frankline]

I hava a new site that I am working on. The site will have prior agreement
with eCommerce sites to include add-ons on their website.

Consider the following example:
My website, ABC.com is targeting ecommerce sites.
For every ecommerce site that sells product X, I want them to include an
add-on that gives buyers the option to purchase service Z if they so
desire.
ABC.com will be communicating with the ecommerce sites through a REST API.

My challenge is how to integrate my service as an add-on into the external
ecommerce sites. This I assume will be in the form of a widget, HTML code,
or a bit of javascript. Something similar to the attached image from
Amazon.com. I'm aiming to make a simple integration with the external sites
to avoid having them do too much on their end.

Is there a best practice on how to handle this?

Looking for a good Django Forum

[Frankline]

Hi all,

Anyone know of a good forum that integrates nicely with django?
Specifically both the Forum and django app should use the same userbase.
Also something that is easy to integrate and theme.

I have been looking at both LBForum and DjangoBB.

Interested to hear from those who have actually implemented it.

./FO

Multiple User Roles design

[Frankline]

*Hi all,*

*I am creating a project that will require two different user roles: An
Instructor role and a Student role. Both will use a common login form. An
Instructor can assign a Student to a Course. Both will have access to
different parts of the system.*

*I wish to know the best way to model this. Currently I'm thinking of the
following:*

*1) Use a single User model having a user_type field*

*2) Create Instructor and Student model that both inherit from base User
model.*

*3) Create an Instructor and a Student group and then assign people to the
correct group based on some value at the time of registration.*

*Is there a better way to handle this apart from the above? What are the
best practices to follow in this case? Or perhaps add a UserProfile?*

*Regards,*
*Frankline*

Re: How to handle model constants

[Frankline]

The reason for my strategy here is because I will need to have a
multi-select instead of a single select for choosing the TaskStatus in the
form i.e. A *Task* can have one or more *TaskStatus*.

Moreover, I will again have to create another class, *SomeClass*, which has
a direct relation to the *Task* model, but can only be associated with only
one *TaskStatus *available from the pool of *TaskStatus*' that were
selected for that *Task*. (Not sure I'm making sense here)

So, YES, the class will be used to compute values based on the stored
constants.

How to handle model constants

[Frankline]

Hi all,

I am getting confused regarding the use of constants and would be keen to
know how the rest of you handle constants in your models. Ofcourse I could
handle it easily similar to how it has been handled here:
https://docs.djangoproject.com/en/1.7/ref/models/fields/#django.db.models.Field.choices

But I wanted to put the constants in a separate class on their own. This is
what I hav so far:

models.py

class TaskStatus(models.Model):

CANCELLED = 0
REQUIRES_ATTENTION = 1
WORK_IN_PROGRESS = 2
COMPLETE = 3

STATUS_TYPES = (
(CANCELLED, 'Cancelled'),
(REQUIRES_ATTENTION, 'Requires attention'),
(WORK_IN_PROGRESS, 'Work in progress'),
(COMPLETE, 'Complete'),
)

status = models.IntegerField(choices=STATUS_TYPES,
default=REQUIRES_ATTENTION)
class Task(models.Model):
status = models.ManyToManyField(TaskStatus,
default=TaskStatus.REQUIRES_ATTENTION)


In my case, a Task can have one or more TaskStatus. I do not wish to store
the TaskStatus in the database since they are simply constants.

Does anyone have a better way of how I can approach this?

Unable to save object with images while using FormWizard in Django 1.7 and Python 3.4

[Frankline]

​Hi all​,
I am having a problem saving a Django form using the *FormWizard
*
while using *Django 1.7* and *Python 3.4*. Below is my code:

*models.py*

...class Advert(models.Model):

adtype = models.IntegerField(choices=ADTYPES, default=1)
price = models.DecimalField(_('Price'), max_digits=12,
decimal_places=2, blank=True, default=0,
help_text=_('Price'),
validators=[MinValueValidator(0)])
...class AdvertImage(models.Model):

def generate_new_filename(instance, filename):
IMAGE_UPLOAD_DIR = "advert_images"
old_fname, extension = os.path.splitext(filename)
return '%s/%s%s' % (IMAGE_UPLOAD_DIR, uuid.uuid4().hex, extension)

advert = models.ForeignKey(Advert, related_name='images')
image = models.ImageField(upload_to=generate_new_filename,
null=True, blank=True)


*forms.py*

 ("ad_details", AdvertDetailsForm),
 ("ad_images", AdvertImageFormset)]

TEMPLATES = {"ad_category": "adverts/advert_category_step.html",
 "ad_details": "adverts/advert_details_step.html",
 "ad_images": "adverts/advert_images_step.html"}


*views.py*

...class AdvertWizard(LoginRequiredMixin, SessionWizardView):

form_list = FORMS
file_storage = FileSystemStorage(location=os.path.join(settings.MEDIA_ROOT))

def get_template_names(self):

...

def done(self, form_list, **kwargs):
advert = Advert()
"""for form in form_list:for field, value in

form_dict = {}
for form in form_list:
form_dict.update(form.cleaned_data)

advert.owner = self.request.user
advert.save()
redirect(advert)


​The problem occurs in the done method while saving the form:

Evaluating variables in a blocktrans block within templates

[Frankline]

Hi all,

I recently had a weird problem in my django templates regarding evaluating
variables within a blocktrans, but I finally figured it out. I guess I just
want to know the reason why it worked, an explanation sort of.

THIS DID NOT WORK
{% blocktrans %}Approve all {{ objects.count }} users{% endblocktrans %}

HOWEVER, THIS WORKED
{% blocktrans with objects.count as objects_count%}Approve all {{
objects_count }} users{% endblocktrans %}

Can someone explain to me the reason behind why the last code statement
worked as opposed to the first one?

Thanks.

Making a field Read-Only in Django

[Frankline]

Hi all,

I'm running Django 1.7 and Python 3.4. I'm trying to make the username
field of my custom model to be read-only. I think this is usually set in
the form. Below is what I currently have in my *forms.py*

class AuthUserChangeForm(UserChangeForm):
"""
A form for updating users. Includes all the fields on the user, but
replaces the password field with admin's password hash display field.
"""
password = ReadOnlyPasswordHashField(label="password",
 help_text="""Raw passwords are not
stored, so there is no way to see this
 user's password, but you can
change the password using 
 this form""")

class Meta:
model = AuthUser
fields = ('username', 'email', 'password', 'is_active', 'is_staff',
'is_superuser', 'user_permissions')
widgets = {
'username': TextInput( attrs={'readonly':'readonly'} ),
'email': TextInput(),
}

def clean_username(self):
# Regardless of what the user provides, reset field to initial value
# Not appropriate to change usernames once set.
return self.initial["username"]

def clean_password(self):
# Regardless of what the user provides, return the initial value.
# This is done here, rather than on the field, because the field
does
# not have access to the initial value
return self.initial["password"]


What I'm I missing here?

AUTH_USER_MODEL does not accept sub application

[Frankline]

I am having problems with my custom user model while using Django 1.7.1 and
Python 3.4.
I have declared a Custom user model in an apps.users.AuthUser. I then have
another application (apps.pets) that will use the AuthUser as a ForeignKey
in a Pet model. See below:

class Pet(models.Model):
owner = models.ForeignKey(settings.AUTH_USER_MODEL, db_index=True,
blank=False, null=False)

This is my scenario:

In my INSTALLED_APPS I have: "apps.users"

If I set AUTH_USER_MODEL="apps.users.AuthUser" the exception is raised when
I run 'runserver':
  File
"/home/frank/.virtualenvs/myproj/lib/python3.4/site-packages/django/contrib/auth/checks.py",
line 12, in check_user_model
cls = apps.get_model(settings.AUTH_USER_MODEL)
  File
"/home/frank/.virtualenvs/myproj/lib/python3.4/site-packages/django/apps/registry.py",
line 201, in get_model
app_label, model_name = app_label.split('.')
ValueError: too many values to unpack (expected 2)


If I set AUTH_USER_MODEL="users.AuthUser" the exception is raised when I
run migrate:
  File
"/home/frank/.virtualenvs/myproj/lib/python3.4/site-packages/django/db/migrations/state.py",
line 89, in render
model=lookup_model,
ValueError: Lookup failed for model referenced by field pets.Pet.owner:
users.AuthUser

Similar issue reported here I guess:
https://code.djangoproject.com/ticket/19845


Does this mean that in AUTH_USR_MODEL setting I have to use
'app_label.model_name' instead of 'apps.app_label.model_name.'? Is there a
workaround for this?

Django 1.7 User login via Email or Username

[Frankline]

Hi all,

Just started looking at Django 1.7. I've followed the tutorials on
https://docs.djangoproject.com/en/1.7/.

However, I find myself in a position where I need to login users based on
either email or username, AND NOT just the username. I want my users to
register using email addresses. This presents some issues with the standard
Django user implementation since the authentication backend is still going
to look for the username when logging in.

I am keen to know how developers here implement this in their own Django
1.7 projects. And also what user models are preferable: AbstractUser or
AbstractBaseUser.

Any links to example tutorials will also be greatly appreciated.

How to implement chained/related dropdown lists in a page

[Frankline]

I am interested in knowing how other developers implement chained dropdown
lists that are dependent on one another. As an example, I have a page/form
that has two dropdown lists. When I select a value from the first select, I
want the second dropdown to be populated by records related to the first
one. This is more of a Country/City situation. Below is how my models look
like.

#models.py
class Category(models.Model):
description = models.CharField(max_length=100)

class SubCategory(models.Model):
description = models.CharField(max_length=100)
category = models.ForeignKey(Category)

I am guessing I will have to involve ajax in one way or the other. Anyone
has an idea on how to implement this?

Forcing Django to use INNER JOIN instead of LEFT OUTER JOIN

[Frankline]

I have implemented search in my Django application to allow searching by
more than one field. This results in Django always using a LEFT OUTER JOIN,
which in my case generates the wrong results. However, when I change the
SQL generated from a LEFT OUTER JOIN to an INNER JOIN, it returns the
correct result.

I am thinking it has to do with the way Q object in my code below.

from django.db import models, transaction...def construct_search(field_name):
if field_name.startswith('^'):
return "%s__istartswith" % field_name[1:]
elif field_name.startswith('='):
return "%s__iexact" % field_name[1:]
elif field_name.startswith('@'):
return "%s__search" % field_name[1:]
else:
return "%s__icontains" % field_name

class CoreSearchMixin(object):
"""Subclasses must define search_fields = [field_1, ...field_n]
where the field is a string, the name of a field, and can contain
the following prefix characters:

'^': the search field must start with the search term, case insensitive
'=': the search field must exactly equal the search term, case insensitive
'@': full-text search

If no prefix is given, any string that contains the search field will match.
"""
search_fields = None
search_form_class = SearchForm

@cachedproperty
def search_form(self):
return self.search_form_class(getattr(self.request,
self.request.method))

def get_query_help_message(self):
"""Returns a comma separated list of fields that are used in
the search, to help the user
create a search.
"""
fields = []
if self.search_fields:
for search_field in self.search_fields:
field = get_field_from_path(self.model, search_field)
fields.append(field.verbose_name.title())
return ",".join(fields)

def get_filtered_queryset(self, queryset):
if self.search_form.is_valid():
self.query = self.search_form.cleaned_data['q']
else:
self.query = None
if self.search_fields and self.query:
orm_lookups =
(construct_search(str(search_field).replace('.', '__'))
   for search_field in self.search_fields)
chained_or_queries = None
for bit in self.query.split():
or_queries = (models.Q(**{orm_lookup: bit})
  for orm_lookup in orm_lookups)
if chained_or_queries:
chained_or_queries =
itertools.chain(chained_or_queries, or_queries)
else:
chained_or_queries = or_queries
return queryset.filter(reduce(operator.or_, chained_or_queries))
else:
return queryset

def get_context_data(self, **kwargs):
return super(CoreSearchMixin, self).get_context_data(
search_form=self.search_form,
query_help_message=self.get_query_help_message(),
search_fields=self.search_fields,
**kwargs
)

How can I ensure that an INNER JOIN is used instead of a LEFT OUTER JOIN in
the case of my code above?

Instantiating a ModelForm with initial values in CBVs

[Frankline]

I am a Django newbie working with Django CBVs and having difficulty setting
initial values for my ModelForm. To give an overview, I am trying to learn
by creating a simple messaging app.

Here is my code:

models.py
-

import datetime
from django.contrib.auth.models import User
from django.db import models
from django.utils.translation import ugettext_lazy as _
from django.utils import timezone

class Message(models.Model):
subject = models.CharField(_("Subject"), max_length=100)
body = models.TextField(_("Body"))
sender = models.ForeignKey(User, db_index=True,
related_name='sent_messages')
recipient = models.ForeignKey(User, db_index=True,
related_name='received_messages')
parent_msg = models.ForeignKey('self', related_name='next_messages',
null=True, blank=True)


forms.py
---

from django.forms import ModelForm
from .models import Message

class MessageForm(ModelForm):
class Meta:
model = Message
exclude = ('sender', 'recipient', 'parent_msg',)


views.py
--

class MessageCreateView(CreateView):
form_class = MessageForm
model = Message
template_name = 'messages/compose.html'

def form_valid(self, form):
form.instance.sender = self.request.user
return super(MessageCreateView, self).form_valid(form)

urls.py
---

...
url(r'^compose/(?P[\w.@+-]+)/$', MessageCreateView.as_view(),
name='messages_compose_to'),
...

As you can see from the urls.py file, I am using the 'recipient' parameter
as such: http://localhost:8000/members/compose/someusername

Now my problem is that I wish to open the compose message view, and
initialize the recipient field by getting the username from the URL, then
using the username from the url to get User with that particular username,
and instantiate the form with it.

Where do I do this, in the view itself or in the form? Unless their is a
better way of how to handle this.

Django authentication by email

[Frankline]

Hi all,

I am thinking of developing a web application where users will have to
login by their email address instead of using their usernames.

Now I know I can do this by writing my own auth backend, but I'm just
curious how the rest of you handle this. Do you normally use third party
packages to handle this instead of writing a custom backend? If so, what
packages would you recommend that are actively maintained?

Any disadvantages to writing my own custom backend?

Thanks.

Re: No settings file in Django tutorial.

[Frankline]

You are trying to change directory through a file i.e. settings.py. This is
obviously not a directory but a file. In any case, it does not exist within
that directory level.

What you need to do is:
$ cd winker
$ ls

And you will see your setting file

I am assuming your directory structure is as follows:

winker
|
|- manage.py
|- winker
|
|- settings.py
|- urls.py
|- wsgi.py

Note that there are two winker directories. Pay attention to the current
directory that you are located in.

Re: What are the steps to build a website?

My advice: Stop making resolutions and just start something. You will be
happier if you do. Along the way, you'll have gained an understanding of
your project to so much more. That is how I learned.

Do not be afraid to make mistakes along the way.

Re: webhosting for django projects with SQLite

+1 for Webfaction. Simple to use. Though I'm using Postgres, SQLite can
also be used IMO.

Using Emails to authenticate

[Frankline]

Hi all,

I guess this question has been asked here a couple of times but I'm going
to ask it anyway.

I'm developing a Django application/website and I have a need to use the
email for authentication instead of username. I'm more keen to find out how
you handle the following:

- The default length of the email field
- Ensuring that the email field remain unique
- Making/Synchronizing the changes with the database

I'm more biased towards handling this myself rather than using the
available packages out there.

Does any one have a pointer to a link on how this is handled?

Thanks.

Regards,
F. O. O.

Re: To Use or Not to Use the admin backend

An example use case is if I need an admin backend with features for reports

To Use or Not to Use the admin backend

[Frankline]

Hi,

I'm creating a site in Python/Django and feel that the admin backend, as
good as it is, may not be a one-fit-for-all situations.

My question is this:

Have any of you ever had a need to have a custom admin backend?

In what example situations would one create his/her own admin backend
rather than using the default admin panel that ships with Django?

What are the disadvantages of rewriting your own backend?

Frank

Starting a Django Project the Right Way

[Frankline]

Hi all,

I found this on the internet and thought I should share it.

http://www.jeffknupp.com/blog/2012/02/09/starting-a-django-project-the-right-way/

By the end of it all, you should have:

1. A fully functional Django project
2. All resources under source control (with git)
3. An environment independet install of your project (using virtualenv)
4. Automated deployment and testing (using Fabric)
5. Automatic database migrations (using South)
6. A solid start to your new site

Re: Advices on what web programming language used in template?

[Frankline]

Hi Yu,

Your question is not really clear. Perhaps take a look at this:
https://docs.djangoproject.com/en/dev/topics/templates/

Since you have mentioned JSP, I'm thinking you are looking at Python/Django
alternatives. If that is the case, then you have the following alternatives:

- Ruby on Rails
- PHP
- Java/JSP/Spring or Struts and even JSF

But then again, it would help if you were more clear on what you need. This
is 'mostly' a Django forum.
