Gatsby: Contentful ID is not the same in the GraphQL query, why?

[Steffi3rd]

Hi,

I just started Gatsby with Contentful and GraphQL.

I playing with GraphQL and I'm wondering why ID is not the same in GraphQuery and Contentful dashboard?

There is a c before the ID, if I remove it (exactly as the Contentful dasboard) I doesn't work anymore.

Contentful dashboard : 15jwOBqpxqSAOy2eOO4S0m

• GraphQL query : 15jwOBqpxqSAOy2eOO4S0m >> doesn't work
• GraphQL query : c15jwOBqpxqSAOy2eOO4S0m >> work

Why?

There are some graphql restriction that ID fields can't start with number so we prefix them with c. Contentful entries should have contentful_id field which does not have that restriction that you can filter by (instead of id)

Thanks for your answer.

I tried contentful_id so, then it seems to work.

But I just found that the edges returns "two nodes" instead one.

Why?

Before (with id)

After with contentful_id

That is interesting - do you use multiple locale/languages? can you add locale and actual id to query results?

Yeah, I add a local : "French", so I have 2 locals (US and FR) in my Contentful.

Can you show me how to query with locale, please? I don't find any documentation about this.

There should be field like locale, node_locale, lang or something like that available to query (and to filter by)

Yeah! Thanks, got it!

With Local

Without local

Final question to close this thread please.

Where I can translate my post on Contentful? I add the local but what's next?

Check https://www.contentful.com/developers/docs/tutorials/general/setting-locales/ - this is more about Contentful than Gatsby and I don't know enough about it to explain properly ;)

@Khaledgarbaya Do you think it's worth adding localization section to gatsby-source-contentful docs?

Thank you very much! Found to enable fields for locale : In the paragraph : Enabling on fields
