How to use anafero to create a referral system in django? - django

I want to create a two-sided benefit referral system, with different types of referrals in django using the anafero app.
I looked at this article and looked at the documentation for anafero and I cannot make sense of it. Can someone please give an simple example of:
What database changes need to be made, i.e. which models need to
be created and how the user object needs to be changed
Which view needs to be created
How to display the referral url in the template

Anafero is outdated. Instead of it you can use pinax_referrals
Install the package as it described in documentation, add middleware etc, synchronize database.
Depending on what do you use for signing up hack the view. In my case I have reimplemented SignUp view and added following lines inside:
profile = user.userprofile
referral = Referral.create(
user= user,
redirect_to= "/"
)
profile.ref = referral
profile.save()
You see that when User signs up the Refferal object is created and saved into User profile. It means that you have to change the model for UserProfile and add additional field:
Import:
from pinax.referrals.models import Referral
Inside model:
ref = models.OneToOneField(
Referral,
null=True,
on_delete=models.CASCADE,
)
Make migrations, migrate, check in the admin if new fields are added, try to sign up and see whether the new Referral object is created and saved.

Django: How to create a user action log/trace with vizualization

I am looking for a tool to track user actions like:
user logged in
user changed password
user got bill via email
user logged
user uploaded image
user send message
...
which I can include into my Django project. Afterwards I want to build queries and ask the system stuff like:
how often did a user a message within a month
how often did a user login within a month
does the user uploaded any images
and I would like to have some kind of interface. (Like google analytics)
Any idea? I am pretty sure that this is a common task, but I could not find anything like this.
There are many ways to achieve that. Try reading this link first. Also, you can use LogEntry for tracking the creation, deletion, or changes of the models you have. Also, it shows you the information you need in the admin panel, or also you can use some other third-party packages.
Or you may want to create your own Model to create logs for your application and this link may help you, but do not reinvent the wheel and analyze your situation.
from django.contrib.admin.models import LogEntry, ADDITION
LogEntry.objects.log_action(
user_id=request.user.pk,
content_type_id=get_content_type_for_model(object).pk,
object_id=object.pk,
object_repr=force_text(object),
action_flag=ADDITION
)
Create a model to store the user actions. OP will want the Action model to have at least two fields - user (FK to the user model) and action (user action).
from django.db import models
class Action(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
action = models.CharField(max_length=255)
Create a way to store the user actions.
def store_user_action(user, action):
action = Action(user=user, action=action)
action.save()
Then if one wants to store when the user changed password, one will go to the view that deals with the change password and call our method store_user_action(request.user, 'changed password') when successful.
To then visualise the user actions, OP can see the records in the Django Admin, create views and templates, ... There are different possibilities.

In Django, is there a way to show the admin for a model under a different app?

I've extended the standard User with a Profile model using a one-to-one relationship:
class Profile(models.Model):
user = models.OneToOneField(User, primary_key=True, editable=False)
# Additional user information fields
This is in an app called account_custom. The issue is that in the admin site, I would like this model to show up along with User under "Authentication and Authorization".
I was able to make this show up in the right place in the admin by setting Meta.app_label:
class Profile(models.Model):
class Meta:
app_label = 'auth'
db_table = 'account_custom_profile'
I set Meta.db_table so this uses the existing database table, and everything seems to function properly.
The problem is that Django wants to generate migrations for this, one in account_custom to delete the table and one in auth to create it again. I'm guessing this would either fail or wipe out the data depending on the order the migrations are run, but the deeper problem is that it's trying to create a migration in auth which isn't part of my code base.
Is there a way around this, or is there some better way to control where a ModelAdmin shows up in the admin site?

Create editable page for user User Account

So my question is what should I look for creating a page which will allow user to add some information after the registration. I took a look at Django Profiles, but it requires lower version of Python (2.7), if I'm not mistaken.
Another thing is I need to create two types of users - I'm thinking of maybe #permission to implement it, but another point is that I want to include something like checkbox while registration, and if user chooses one type of user, he will be allowed to see default account page for this type of user which he should fill up.
I'm running Django 1.10.5 and Python 3.6.0.
Thanks in advance.
If you want to add custom fields to your user object take a look at custom user model django implementation. Then, for updating user object you can just use generic update view, it will look something like this:
from django.contrib.auth import get_user_model
class UserUpdateView(UpdateView):
model = get_user_model()
fields = ['field1', 'field2', 'field3']
template_name = "core/user_edit.html"

Custom Django Authentication

I have an model named Customers(username,password ..etc) and also an model named User(username,password...etc).
I want to create two different APIs with different authentication.
One should authenticate with the User username,password
and the second should authenticate using the Customers username,password.
Any idea on how can I do this?
Thank you!
I suggest the following options:
1.
I am assuming User model is the "real" user of your app. If this is true use the django's default User model class. It will work out of the box.
For the Customer model, make it inherit from AbstractBaseUser, this will give you password functionality out of the box and you can add other fields as per your need.
Now you can create 2 different urls for login. 1 url for user which checks in the User model and the other for the customer model. This avoids any confusion for everyone.
If you prefer a single url, you have to mention the model class along with username and password to know in which table to verify them.
2.
Create two profile models: UserProfile and CustomerProfile
Each will have a one to one relationship with the django's default User model.
Basically a User can have the profile of a "real" user or of a customer.
In this case when you are creating any User you have check if you want to attach a UserProfile or a CustomerProfile.
In this case it makes sense to just use a single login url. From the user's login information you can first fetch the user from the User table and then check if it is a customer or not by running a query in the CustomerProfile table.
I recommend you to use the django.contrib.auth.user class for your classical authentication. You can either inherit from that class or add a OneToOne relation to your own model as follows
from django.contrib.auth.models import User
class YourUser(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
For the rest of your question you should add some more details and even some pieces of your code.

Extending the User model in django

http://scottbarnham.com/blog/2008/08/21/extending-the-django-user-model-with-inheritance/
When it comes to extending the User model, the above article list two methods: the old way (ForeignKey) and the new way (User model with inheritance). But at the same time, this article dates back to Aug 2008.
I am using Django's development version.
Would you recommend Extending the Django User model with inheritance or by using ForeignKey?
I read in a couple of posts that extending django.contrib.auth.models.User is not recommended, so I will not be looking at that.
AFAIK, the cleaner approach - if this can fit in your project architecture - is to have a distinct user profile model, and use the AUTH_PROFILE_MODEL setting to link it up to the Django User model.
See the Django Doc about storing additional information for Users
Dominique Guardiola is right. Use the AUTH_PROFILE_MODEL. James Bennett reiterated this in his 'Django in Depth' talk. http://www.youtube.com/watch?v=t_ziKY1ayCo&feature=related around 1hr:37mins.
Decide on the application where we want to house our user's profile, let's call it BngGangOfFour.
Define a Model class, lets name it UserProfile for clarity, and give it the extra field(s) we desire.
BngGangOfFour/models.py
from django.contrib.auth.models import User
class UserProfile(models.Model):
user = models.OneToOneField(User) #notice it must contain a 1 to 1 field with the auth user.
last_ip_address = models.CharField(max_length=20, default="")
Edit settings.py to designate our newly created model as the user profile.
settings.py
....
AUTH_PROFILE_MODULE = 'BngGangOfFour.UserProfile' #not case sensitive.
....
Access the profile directly off the user objects.
BngGangOfFour/views.py
....
def index(request):
if request.user.get_profile().last_ip_address = "127.0.0.1":
print("why hello me!")
return render_to_response('index.html', locals(), context_instance=RequestContext(request))
Sip a cold beer and call it a day.
The only time you can cleanly get away with extending User via inheritance is if you're writing an auth backend which will return an instance of the appropriate model instead.
