Allow create user plans on Django Admin

[eduardo-matos]

Currently there is no way to create a user plan on Django Admin. The user field should be displayed.

This functionality is good for manual registration.

Hi there @eduardo-matos, Currently you can manually create a UserPlan by first creating a new User in the admin and then edit his UserPlan which is automatically created after user-creation. Is this what you were looking for?

As an aside: in order for this to work, you need at one plan marked as "default" plan. That way, all created users will immediately be assigned this plan after creation.

I have some users that were created before including the django-plans app. The only way I can associate these users with an userplan is by editing via shell, which I was trying to avoid.

My idea was to create a new userplan manually (via admin page), choosing an existing user in the "create userplan" page. Since the "user" field is omitted, There is no way to do that.

A quick fix is to override UserPlan inside your admin

from plans.models import UserPlan
from plans.admin import UserPlanAdmin

class UserPlanMyAdmin(UserPlanAdmin):
    fields = ('user', 'plan', 'expire', 'active')

admin.site.unregister(UserPlan)
admin.site.register(UserPlan,UserPlanMyAdmin)

Having user editable/writeable on the admin has one annoying con as well, which is when there are many users and simply loading them in a "select" html widget will cause load, especially when there are many users in the database.

If Django admin had a default feature to have a search-friendly select box for related field it would be much easier.

To learn more about this problem you may have a look at https://stackoverflow.com/questions/14912872/django-admin-dropdown-of-1000s-of-users.

To solve such issue there are:

• https://github.com/applegrew/django-select2
• https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.raw_id_fields

My vote for the second option which is using raw_id_fields in admin panel.
Which gives something like:

The solution provided by @maxpaynestory is also an hack that can be done as well, but still will have the same problem that I described.

I am open for any suggestion here and would love to discuss it.

For the problem with users created prior introducing django-plans, I would recommend introducing adminaction to the sources. The code might be pretty simple:

for user in UserProfile.objects.filter(userplan=None):
     UserPlan.objects.create(user=user, plan=Plan.objects.get(default=True))

Although there might be other cases, when the manual editation of UserPlans would be needed.

An complete fix here is to use @maxpaynestory solution with Django 2+ autocomplete.

class UserPlanMyAdmin(UserPlanAdmin):
    fields = ('user', 'plan', 'expire', 'active')
    autocomplete_fields = ['user', 'plan']
