I have error in sample_erp tutorial document!

[morteza06]

Greetings
I am a newbie in Python.
I followed the guide,
when I click on keys: [Clients][Expense][Products][Sales]
I have a error occurs!!
OR Key in left side .
Although all the data I entered in sample_erp was saved in admin.
All the add buttons work fine and then the error message comes.

`

You’re seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard page generated by the handler for this status code.

Got hit with the exact same issue.

I'm new to Django and RA framework too but I suspect it might be something to do with the addition of search_help_text in Django 4.1

get_changelist_instance() has the positional argument self.search_help_text on line 848 (django/contrib/admin/options.py) which is not reflected in the RaChangeList() class.

I found that adding search_help_text to the end of the positional arguments on line 83 and 87 of ra/admin/admin.py cleared the error (added it to both init and super).

As I've said I'm new to this too so I have no clue yet why (or if) this only seems to affect the sample_erp tutorial

Hopefully the whole RA framework will be updated to work with Django 4 but adding the argument above seemed to workaround this specific error.

A new version is released with this, and much more, fixed and added

I also have a problem with the sample_erp

In the models.py file

from django.db import models
from erp_framework.base.models import EntityModel, TransactionModel, TransactionItemModel, QuantitativeTransactionItemModel
from erp_framework.base.registry import register_doc_type
from django.utils.translation import gettext_lazy as _

What is this from erp_framework.base.registry import register_doc_type

There is no registry.py file in the base folder.

Can you help on this?
Thanks.

Hello , Thanks for reporting @ShopCartz
The sample ERP tutorial will be revised as there are some big changes in the codebase.

You can skip the doc type registry, i will post here once i push the documentation updates.

Let me know if you face other issues .

Similar issue with Docs. I've commented out the registry bit but when I attempt makemigrations I get.

from erp_framework.admin.admin import erp_framework_site, EntityAdmin #, TransactionAdmin, TransactionItemAdmin
ImportError: cannot import name 'erp_framework_site' from 'erp_framework.admin.admin' (/home/myuser/apps/myproject/env/lib/python3.10/site-packages/erp_framework/admin/admin.py)

This in admin.py
from erp_framework.admin.admin import erp_framework_site

Django 4.2 Python 3.10

Really looking forward to getting ERP going. Looks awesome.
