CASE is an expression NOT a statement, which is made clear when referencing the official documentation i.e. a single case expression, regardless of number of branches, can return a single value. It does not allow you to run conditional parts of your query.

In addition you cannot compare NULL with = you use IS NULL.

I think the following contains the same logic you are aiming for, but it should trivial to tweak it now that you can see where you were going wrong.

QUESTION

Cannot assign "'1'": "staff.staff_type" must be a "staff_type" instance. Django Error in OneToOne field

Asked 2021-Jul-11 at 10:15

I am working on a small django-python project which has two models "staff_type" and "staff". In the staff_type model, only designation and date fields are populated. And in the staff model, there is OneToOneField relation of staff_type. Means whenever a user want to add staff first he/she will have to add staff_type and then in the staff module, user will choose the staff type (designation) from a select menu in which all the staff_type are shown respectively.

Now, whenever a user select any designation (staff_type) and fill the entire form, I want to store the selected staff_type id in the staff model/table.

Note: I have tried this from django admin, and it works perfectly but I want to do the same work in my own designed templates.

The problem is that you are sending number to Staff model into the field "staff_type". You either need to cast it to staff_type, or put an instance there

Best practices for often repeating background tasks in django and pythonanywhere

Asked 2021-Feb-25 at 10:55

So, I am currently working on a django project hosted at pythonanywhere, which includes a feature for notifications, while also receiving data externally from sensors through AWS. I have been thinking of the best practice in order to implement this.

I currently have a simple implementation which is a view that checks all notifications and does the actions as needed if required, with an always-on task (which simply means a script that is running independently) sending a REST request to the server every minute.

Server side:

views.py:

ANSWER

Answered 2021-Feb-25 at 10:55

To use Django background tasks on PythonAnywhere you need to run it using an always-on task, so it is not an alternative, but just the other use of always-on tasks.

You can also access your Django code in your always-on task directly with some kind of long-running management command, so you do not need to hit your web app with a special request.

Check for unique constraint inside the save method

Asked 2020-Oct-09 at 05:52

I have a model on which the unique_together parameter is not working. The reason is that most of the times the "client_repr" variable is set on the save() method. If someone creates a task with the same ('client_repr', 'task_type'... ) combination the model won't detect it because the "client_repr" value is null until the end of the save() method.

How can i call for a unique constraint verification inside the save() method?

Answered 2020-Oct-09 at 05:52

Option 1: Using clean()

It's not directly what you asked, but it's generally more django-friendly and does not require weird things like overriding save()

create golang bindings for a python module

Asked 2020-Oct-07 at 13:30

I want to write golang bindings for an existing (third party) Python module. The purpose is that I want to use the API that the Python module provides in Golang.

I already found golang bindings for Python's C API (go-python3 for py3 and go-python for py2), but I still haven't figured out how to translate a relatively complex Python module into Golang (i.e. how to deal with type safety in go for unsafe inputs and returns in python, etc).

What would be a good approach? Are there any pre-existing tools in that space? Are there any good examples for Golang bindings for Python code? (I couldn't find many tbh).

Any ideas or feedback would be much appreciated. Thanks a lot!

I want to use the API that the Python module provides in Golang.

Calling Python from Go is detailed recently in "Python and Go : Part I - gRPC" by Miki Tebeka.
You can see an example in ardanlabs/python-go/grpc

But, as shown in their next two articles, you can also:

compiled Go code to a shared library and used it from the Python interactive shell.
use a Python module that hides the low level details of working with a shared library and then package this code as a Python package.

Full example: ardanlabs/python-go/pyext.

Reformat the date times into one of the RFC5545 formats. Please see the RFC5545 specifications instructions for the datetime formats: https://tools.ietf.org/html/rfc5545#section-3.3.5.

There are 3 accepted datetime formats:

Local or 'floating' eg: 19980118T230000
Date with UTC time eg: 19980119T070000Z and
Date with local time and timezone reference eg: TZID=America/New_York:19980119T020000

Django: psycopg2.errors.UndefinedColumn: column "page_image" of "pages_page" relation does not exist

Asked 2020-Sep-04 at 21:42

Here is a brief backstory. I am using the Mezzanine CMS for Django. I created some models that inherited from the Mezzanine models. This caused an issue in my Postgres database, where one object was present in two tables. When I would try searching my site for a post, I would not get results from one table.

So, here is where I believe I messed up. I reverted my models to how they were before this issue. This meant that there was still a table in my database for those models, so my search function still wouldn't work. I wanted this relation gone, so I did something very stupid and deleted the entire database. This was fine for my local development, because I just recreated the database and migrated.

When I try deploying this project of mine with the newly created postgres database onto DigitalOcean, I get to this command:
$ python manage.py createdb --nodata --noinput which gives me the error:

Django "Illegal mix of collations" for MySQL utf8mb4 table

Asked 2020-Apr-17 at 23:16

I have reviewed other questions related to this topic, such as django python collation error

However, the solutions say to encode the table using a utf8 charset. That is not a viable solution for our modern Django app running on a utf8mb4-encoded database.

In my case, I need to enforce a charset or collation in the Django generated query, or in the DB itself, when utf-8 characters are being passed in (from a call to model.objects.get_or_create(), I believe with an emoji character being passed in one of the kwargs fields.)

I'm getting this error:

django.db.utils.OperationalError: (1267, "Illegal mix of collations (utf8mb4_unicode_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '='")

Any advice welcome. Thanks!

Install go-python

With Go 1 and the ``go`` tool, ``cgo`` packages can’t pass anymore additional ``CGO_CFLAGS`` from external programs (except pkg-config) to the "fake" ``#cgo`` preprocessor directive. ``go-python`` now uses ``pkg-config`` to get the correct location of headers and libraries. Unfortunately, the naming convention for the ``pkg-config`` package is not standardised across distributions and OSes, so you may have to edit the ``cgoflags.go`` file accordingly.
