Creating author pages with Gatsby and Sanity Studio

27 replies
Last updated: Apr 17, 2020
Hi, I'm trying to create a page (using Gatsby) for every author. I've got it to where a page is created with all their information entered into Sanity Studio, but I'd like to have all of their posts on the site displayed on the page too. Is there a way anyone has found to make this happen?

You can do a graphql filter with the authorId on an allSanityPost query.
Apr 17, 2020, 4:12 AM
something like allSanityPost (filter: { author: { id: { eq: $authorId }}})
Apr 17, 2020, 4:16 AM
Assuming you passed the authorId on your createPage context
Apr 17, 2020, 4:16 AM
Thanks for your help on this!. Here is what I have in gatsby-node.js:

const authorEdges = (result.data.allSanityAuthor || {}).edges || []

const _id = authorEdges._id

authorEdges

.forEach((_edge_, _index_) => {

const {name, slug = {}} = edge.node
`const path = `/author/${slug.current}/``

`
reporter.info (
Creating author page: ${path}
)`

createPage({

path,

_id,

component: require.resolve('./src/templates/author-page.js'),

context: _id

})

})

And then this is in the template file query:

posts: allSanityPost(filter: {authors: {elemMatch: {author: {_id: {eq: "{$_id}"}}}}})

No luck so far though, do you have any suggestions of what I might be doing wrong here?

The author is an object
Apr 17, 2020, 7:44 PM
It has a person inside it
Apr 17, 2020, 7:44 PM
Heres what it looks like
Apr 17, 2020, 7:45 PM
You’re missing another nested object person on the elemMatch
Apr 17, 2020, 7:47 PM
You also don’t need paranthesis. You can just do { eq: $_id }
Apr 17, 2020, 7:49 PM
Oh interesting, I don't have person in my schema, I have 'author' instead
Apr 17, 2020, 8:02 PM
Try the ___graphql playground that gatsby provides, it has an autocomplete feature to help with missing parameters. If you have an author on your schema, then use author instead to reach it’s _id
Apr 17, 2020, 8:06 PM
I got the query from the GraphQL playground.When I query 
allSanityPost(filter: {authors: {elemMatch: {author: {id: {eq: "$_id"}}}}})
I get this error message:

Variable "$_id" is not defined by operation "AuthorPageTemplateQuery".
Apr 17, 2020, 8:08 PM
So with the playground you cannot query with $_id since it doesn’t know where it’s coming from
Apr 17, 2020, 8:09 PM
Query one of your authors and grab it’s id and copy paste that to the filter
Apr 17, 2020, 8:09 PM
I get that error message when I query it in my template file
Apr 17, 2020, 8:09 PM
It should work
Apr 17, 2020, 8:09 PM
I was hoping to do this programaticaly where it would automatically create one for every author. Is that possible?
Apr 17, 2020, 8:10 PM
Di you do do a query ($_id: String!)
Apr 17, 2020, 8:11 PM
You need to define it first on your query
Apr 17, 2020, 8:12 PM
yep, this is what I've got:
query AuthorPageTemplateQuery($_id: String!) {
Apr 17, 2020, 8:13 PM
Oh i got
Apr 17, 2020, 8:17 PM
Remove the “” on your filter
Apr 17, 2020, 8:18 PM
It should be { eq: $_id }
Apr 17, 2020, 8:18 PM
Not { eq: “$_id” }
Apr 17, 2020, 8:19 PM
Oh I finally got it! Thank you so much. I don't know why I couldn't get _id to work, but I tried passing the author name through and matching to that, that worked for me. For anyone's future reference, the final query I used on the template page is:
`export const query = graphql``

query AuthorPageTemplateQuery($name: String!) {

post: sanityAuthor(name: {eq: $name}) {

name

_id

image {

...SanityImage

alt

caption

}

slug {

current

}

_rawBio

}


posts: allSanityPost(filter: {authors: {elemMatch: {author: {name: {eq: $name}}}}}) {

edges {

node {

id

authors {

author {

name

id

}

}

categories {

title

_type

_id

id

color

}

publishedAt

mainImage {

...SanityImage

alt

caption

}

title

_rawExcerpt

Action1Title

Action1URL

slug {

current

}

}

}

}

}
```

and this is the function in my node file:

async function createAuthorPages (_graphql_, _actions_, _reporter_) {

const {createPage} = actions
`const result = await graphql(``

{

allSanityAuthor {

edges {

node {

name

_id

slug {

current

}

_rawBio

}

}

}

}
``)`


if (result.errors) throw result.errors


const authorEdges = (result.data.allSanityAuthor || {}).edges || []

const _id = authorEdges._id

authorEdges

// .filter(edge => !isFuture(edge.node.publishedAt))
 
.forEach((_edge_, _index_) => {

const {name, slug = {}} = edge.node

// const dateSegment = format(publishedAt, "YYYY/MM");
 `const path = `/author/${slug.current}/``

`
reporter.info (
Creating author page: ${path}
)`

createPage({

path,

name,

component: require.resolve('./src/templates/author-page.js'),

context: name

})

})

}

Thanks so much again Vince
Apr 17, 2020, 9:24 PM
You might want to use the id since that’s unique. You might end up having authors with the same name. But yeah your query works because you don’t have the parenthesis on the $name. If you try it with _id it should work as well
