You can combine multiple predicates in a single query, for example querying for a certain custom type with a given tag.
You simply need to put all the predicates into a comma-separated array.
Here is an example that queries all of the documents of the custom type "blog-post" that have the tag "featured".
response = api.query([
Prismic::Predicates.at("document.type", "blog-post"),
Prismic::Predicates.at("document.tags", ["featured"])]
)
# response contains the response object, response.results holds the documentsHere is an example that queries all of the documents of the custom type "employee" excluding those with the tag "manager".
response = api.query([
Prismic::Predicates.at("document.type", "employee"),
Prismic::Predicates.not("document.tags", ["manager"])]
)
# response contains the response object, response.results holds the documents
