Enhancement: Create new `isPublishDate` and `isModifiedDate` property to define date types

Discussed in #278

Hi

I've followed the documentation to try & get custom publish and last mod dates working - so far without success

My workspace editor settings appear correct

And I have edits frontmatter.json in my project also

"frontMatter.taxonomy.dateField": "publishedAt",
"frontMatter.taxonomy.modifiedField": "lastMod",

However, the FrontMatter editor fails to pick up those field value and sets a field "date" when I use the Dashboard to update

I am running on the Beta

Any tips appreciated

@jmatthewpryor you will now be able to test it out in the new beta version.

Information to migrate to these new settings can be found here: https://beta.frontmatter.codes/docs/troubleshooting#feature-migrations

works fine for me following those instructions @estruyf

I spoke too soon @estruyf - I keep getting an entry added to my MDX file when I first open the FM edit panel

This is my content defs

  "frontMatter.taxonomy.contentTypes": [
    {
      "name": "default",
      "previewPath": null,
      "pageBundle": false,
      "fields": [
        {
          "title": "Title",
          "name": "title",
          "type": "string"
        },
        {
          "title": "Description",
          "name": "description",
          "type": "string"
        },
        {
          "title": "Publishing date",
          "name": "publishedAt",
          "type": "datetime",
          "default": "{{now}}",
          "isPublishDate": true
        },
        {
          "title": "Updated date",
          "name": "lastMod",
          "type": "datetime",
          "default": "{{now}}",
          "isModifiedDate": true
        },
        {
          "title": "Article preview",
          "name": "preview",
          "type": "image"
        },
        {
          "title": "Is in draft",
          "name": "draft",
          "type": "draft"
        },
        {
          "title": "Tags",
          "name": "tags",
          "type": "tags"
        },
        {
          "title": "Categories",
          "name": "categories",
          "type": "categories"
        }
      ]
    }
  ],

Despite that, when I open an MDX file via the FM dashboard, it auto adds the following to the frontmatter section

date: "{{now}}"
Not sure how to fix that from here

[estruyf]

@jmatthewpryor if I understand it correctly, when you open an MDX file, without the lastMod or publishedAt date set in your front matter, it gets automatically added?

Ok, accidentally reproduced it, now I understand what is happening 🤓

[estruyf]

This commit should fix the above issue.

that works for me now too - thanks
