Schema definition issues with solution for Gatsby source plugin for Kontent

Issues

• Mainly kontent-ai/gatsby-packages#106
• Might fix kontent-ai/gatsby-packages#107 as well

Solution

Queries with complicated filter:

  query BeltIdentifierTypeQuery(
    $url_slug: String!
    $language: String!
  ) {
    pitches: allKontentItemBeltPitch(
      filter: {
        usedByContentItems: {
          elemMatch: {
            system: { type: { eq: "belt_series" } }
            elements: {
              belt_type: {
                linked_items: {
                  elemMatch: {
                    elements: { url_slug: { value: { eq: $url_slug } } }
                  }
                }
              }
            }
          }
        }
      }
      ...

Could be extracted to isUsedInBeltSeries and beltTypeUrlSlug fields precalculated in gatsby-node.js and then use in the filter:

Example

query getPitchesInBeltSeriesByUrlSlug($url_slug: String!) {
  allKontentItemBeltPitch(filter: {fields: {beltTypeUrlSlug: {eq: $url_slug}, isUsedInBeltSeries: {eq: true}}}) {
    nodes {
      internal {
        type
      }
      system {
        name
        codename
      }
      ...
    }
  }
}

i.e. with query variables:

{
  "url_slug": "belt-type-1"
}
