Lume Relations does not work?

[officialrajdeepsingh]

When I use the following code on my website, it doesn't show anything.

site.use(
relations({
  foreignKeys: {
    article: "article_id",

    author: "author", // replace to the author_id

  }
}));

In my posts, I already mention the author meta tag.

Sit culpa elit excepteur ea rest articles....

With article_id, it works fine, but it is a problem to remember the id every time. So I replace it with the author's name, but it is not working.

site.use(
relations({
  foreignKeys: {
    article: "article_id",

    author: "article_id",

  }
}));

The relations foreign Keys only accept the integer value as an id?

In your first example:

site.use(
relations({
  foreignKeys: {
    article: "article_id",
    author: "author",
  }
}));

The problem is author key and value cannot be equal, because the plugin creates a new author property that overrides your author value. The id can be anything, it's not limited to integers. Probably something like this should work:

site.use(
relations({
  foreignKeys: {
    article: "article_id",
    author: "authorName",
  }
}));

If you don't want to use the id field to link the pages, you can change it to any other value, but note that this will affect to all relations (cannot be configured individually per relation). Example:

site.use(
relations({
  idKey: "slug",
  foreignKeys: {
    article: "article_slug",
    author: "author_slug",
  }
}));

In this example, I've configured the idKey as "slug" so all related pages must have a slug key. And, for consistency, I've changed the foreign keys names to include _slug as suffix.

Thanks @oscarotero

Sorry I can use the following ways to add a relationship with the article and author. But it is not working.

site.use(
  relations({
    foreignKeys: {
      article: "article_id",
      author: "author_name",
    }
  }));

I think it's cause author_name is the foreign key, so it must be used in the post, not in the author (that must be the id).

I'll try to explain better how it works:

• idKey The key used to identify a page. By default is id.
• typeKey The key used to define the type of a page. By default is type.
• foreign key: The key used by other pages to relate themselves to a page.

The first two values are the same for all pages, and by default are id and type. This means all pages must have these two values. For example, your author could be type=author and id=jeanne-ballard.

The foreign key is different per type. For example, pages of type author may have the foreign key author_id. This is used by other pages to reference this page. For example, your post could have the variable author_id=jeann-ballard, so it's related with the page of type author and id jeanne-ballard.

Anyway, I'm working on improve this plugin to make it more easy to work with. Probably there will be changes in the incoming Lume 1.13.0.
