title: Where do you pass the :ignore-missing-mapping? keyword in reitit swagger to ignore unconvertable schemas?
body: <p>I've been following the <a href="https://github.com/metosin/reitit/blob/master/examples/ring-swagger/src/example/server.clj" rel="nofollow noreferrer">ring-swagger server.clj example</a> to set my own http server but with prismatic/schema coercion.</p>
  <p>Everything works just fine when my leafs are of basic type such as s/Str or s/Int, but I can't get it to work with (s/pred pos-int?) for example.</p>
  <p>Every time I try to get the server's swagger API page, an error is thrown:</p>
  <pre><code>don't know how to convert clojure.core$pos_int_QMARK_@1870c292 into a Swagger Schema
  </code></pre>
  <p>I understand I should be using the <code>:ignore-missing-mapping? true</code> setting from the <a href="https://github.com/metosin/ring-swagger#customizing-swagger-spec-output" rel="nofollow noreferrer">ring-swagger documentation</a> but I have no idea where do I pass that.</p>
  <p>I'm using reitit v0.5.12, and I see that inside <code>reitit-schema</code>, the settings I pass from my router definition are not passed to the <code>schema-tools</code> ns functions when I pass the <code>:coercion reitit.coercion.schema/coercion</code> coercion: <a href="https://github.com/metosin/reitit/blob/master/modules/reitit-schema/src/reitit/coercion/schema.cljc#L52" rel="nofollow noreferrer">https://github.com/metosin/reitit/blob/master/modules/reitit-schema/src/reitit/coercion/schema.cljc#L52</a></p>
  <p>I'm not sure how can I setup a prismatic-schema to work with swagger, besides constricting myself to only use plain schemas leafs such as s/Int, s/Str, etc.</p>
