Issues to change the documentation
#16076

PROTECTION_RULES extended by an example of what works in the WEB UI.

Fixes: #1234

[jeremystretch]

Please change this to regular text, extending the paragraph above. Text emphasis should be used sparingly.

[jeremystretch]

All images presented in the documentation must be included in the code base.

[arthanson]

@LHBL2003 you actually need to include the image in the codebase and git-add it to the code so that it appears in the PR.

[LHBL2003]

OK feels strange. But this means that the image is displayed as a path. :)

[LHBL2003]

@arthanson I'm not sure if I understand you correctly. Do I have to insert the image paths "![ Image ] ( https://..." into the code block python... ![ Image ] ( https://.... Or do you think I have to upload the images as an attachment on the Git Hub page so that they get an image ID "![IMG_0047](https://".
Sorry for the stupid question, I have now done the latter. Because I don't have a code base for the 2nd image.

[jeremystretch]

It is not necessary to specify the navigation path.

Suggested change

	**Path:**
	- WebUI (v3.x.x) --> Admin --> Configuration Config Revisions --> Add (or Edit last Config)
	- WebUI (v4.0.0) --> Admin --> Configuration History --> Add (or Edit last Config)

[jeremystretch]

As above, please convert this to regular text in paragraph form.

[LHBL2003]

Revised according to jeremystretch suggestion.

[LHBL2003]

I hope I did it right. At first it was difficult to find out how to revise the file. I hope I have triggered everything so that the review can continue. My first revision :D

[LHBL2003]

Image inserted in code area

[LHBL2003]

Image uploaded as an attachment so that it has an image ID.

[arthanson]

@LHBL2003 see (https://raw.githubusercontent.com/netbox-community/netbox/develop/docs/index.md) for an example, specifically the line:

[![NetBox UI](./media/screenshots/home-light.png)](./media/screenshots/home-light.png)

It points to this location in the source-tree (https://github.com/netbox-community/netbox/tree/develop/docs/media) so you will want to put any images into the source-tree in the appropriate place in under docs/media and make the link point to that. We do this so the documentation will work for people who locally install it.

[LHBL2003]

Images netbox UI path specification.

[LHBL2003]

For God's sake, I would never have thought of that. You need documentation to insert pictures into the documentation :D
Now I know why there are only a few pictures in the folder :D Pictures are worth a thousand words. But I wouldn't have thought that you need a thousand words to show a picture :D
Thanks for the help. I hope it fits now. At least the pictures are displayed under the Change text.
I now have a question mark icon where the image should be, but hopefully that will disappear when it is where the documentation is hosted.

[LHBL2003]

Your are more familiar with the whole subject? If I understand it correctly, then example 1 is something that is stored in configuration.py. If so, then we should add it to the configuration that this must be entered in Configuration.py.

PROTECTION_RULES = {
    "dcim.site": [
        {
            "status": {
                "eq": "decommissioning"
            }
        },
        "my_plugin.validators.Validator1",
    ]
}

Wouldn't it make sense to document that you have to leave out the code if you don't use a validator class?

,
        "my_plugin.validators.Validator1",

Because I didn't understand it as a Newbie. And from current experience, I would say that the Codeshnipsel is interesting, but sometimes there are misunderstandings. I don't think the last comma at the end of the code snippet belongs there at all. But I don't know enough about the subject for that.
