hello, I developed a django website ,can anyone suggest me best resource to learn howto deploy it on Linux server

*URGENT : * Pipenv install package-name will update other package too, but i don't want to update him other packages and i also didn't want to verify specific version in Pipfile. What are the other solutions or suggestions you have ?

There are just two options: you use the latest versions of every package or you use the spesific versions of each package. It doesn't work the way you want, as to have a specific old version of one package and the latest version of another one which is incompatible with the previous.

Try poetry

Thanks but the problem arises when you are working in big project and you want to install some package but that'll update the other package where you have no idea that this update will work for the module or not.

Try poetry

Is this correct ref : https://python-poetry.org/

You could try DigitalOcean. Their server is Linux based. Go for it. There are a lot tutorials provided by DigitalOcean itself.

These versions of the packages are obviously incompatible and cannot work together.

How to make history for a model that show me the old and new changed value in a field? I think to make history model to each model which have the same fields and when the user create or update the data from the first model go the second model too.

Please anyone help me out.

How to make history for a model that show me the old and new changed value in a field? I think to make history model to each model which have the same fields and when the user create or update the data from the first model go the second model too.

One of the approaches is to have second field in the same model to store the previous value if you need just one old value, or you may create another model, as you have done, and put there a foreign key to the main model and a timestamp field, so you can store the full history of changes. To make it simpler, you may create basic class with model fields (inherited from "object") and then use multiple inheritance from it and models.Model to create the real model class. Then, in the history model you'll just need to add 2 fields I've talked about, and when you want to add or change fields, you just edit the base class, and all changes will automatically go into both models. It depends on your real needs.

Also, be sure to create a history model instance only for updating the main model, but not for its initial save after creation.

Look into your migrations. It seems like you are using some additional application, like django-reversion.

Just delete the migration folder and run it again from scratch may this helps

Add the default value to it. Look into migrations to find out from which application it comes.

Then try adding all the fields from views.py

Okay

That d be perfect...

In my application I searched for this keyword manager_slug it is not there any where

Hello....I have been stuck from morning how to solve module not find error

??

I think you need to install lower version of that module

How do I do that

Can you please tell me ??

Error in which module

Should I delete reversion and give it a try

I guess you already have data in that table and now you're trying to add django-reversion which adds own fields to your model, and those fields neither have default value nor can be NULLed. That cause the integrity error, because there's no proper value for these new fields which could be written into the table for existing data.

Error in which module

Views

This is import error

Ohh sory

And another is in urls error

What kind of errors?

What version of Python are you using?

I will message personally the media file

What version of Python are you using?

Latest one 3.8

It's is working

Then after adding reversion and creating migration, edit it manually to set default value to empty string. Then migrate and after that manually edit your table in the database to remove the default value. Thus you'll have proper table structure and working application. But remember that already stored data will have incorrect values in new fields. Edit them somehow.

Latest one 3.8

With which version of pip have you installed DRF? Are you sure it was pip3 and not simply pip (which refers to Python 2.x)?

Is rest_framework the first registered application in settings.py? Isn't there any typo, like missed comma or underscore? Sorry for my errors, English is not my native language and I did not have any practice for rather long time.
