Can you please post the relevant parts of what you have so far?

The Pathom docs give a pretty clear example I think: https://blog.wsscode.com/pathom/#_parameters

corresponding fulcro section: https://book.fulcrologic.com/#_parameters

I am not able to get the parameters with (-> env :ast :params)

Here is my code

(defresolver werkers-by-service-location-resolver
  [env {:location/keys [position] :service/keys [id] :as input}]
  {::pc/input  #{:location/position}
   ::pc/params [:service/id]
   ::pc/output [{:werkers-by-service-location [:werker/id]}]}
  (log/spy input)
  (log/spy (-> env :ast :params))
  {:werkers-by-service-location []})

I believe ::pc/params is for pc/defmutation and not pc/defresolver.

I took it out, no change.

And the parameter will not be coming in the input argument (second one) of the resolver, it's in the env.

so you query for [([:location/position "something"] {:service/id 123})] but you do not see the 123 anywhere inside the env / ast?

Correct.

Can you show the query portion please?

[({[:location/zipcode "85286"] [:werkers-by-service-location]} {:service/id #uuid "ffffffff-ffff-ffff-ffff-000000000100"})]

I have a resolver from :location/zipcode to :location/position It is working properly.

I see a position in my input to my resolver.

Is the zipcode resolver receiving the param?

Ah. Maybe so…

Nope. That’s not it. Here’s the output: (-> env :ast) => {:type :prop, :dispatch-key :werkers-by-service-location, :key :werkers-by-service-location}

I can replicate it, Using my minimalist-fulcro-template-backendless' person resolver, the env contains :ast {:type :prop, :dispatch-key :person/name, :key :person/name} and the only place that seems to have the params is :com.wsscode.pathom.core/root-query which is [({[:person/id 1] [:person/name]} {:service/id 123})]

Ok. Thanks @U0522TWDA!

I think I recall running into situations where a join param didn't work but placing the param on the ident did. Try that?

Fulcro only supports params at the top level. The query above was actually generated by (df/load! [:person/id 1] (rc/nc '[:person/name]) {:params {:service/id 123}})

So, any suggestions on how to parse the ::p/root-query?

I would ask @U066U8JQJ for help figuring out why the params are inside root-query but not inside :ast , as https://clojurians.slack.com/archives/C68M60S4F/p1646083719605539?thread_ts=1646081061.832729&cid=C68M60S4F. I think the fact that the ast being {:type :prop, :dispatch-key :person/name ...} indicates that we are kind of "one level down" in the ast and we would need to get to the parent level, where :type join to see the params. I am not sure how this is supposed to work.

Perhaps https://github.com/fulcrologic/fulcro-rad/blob/develop/src/main/com/fulcrologic/rad/pathom.clj#L110 is relevant here

Thank you @U0522TWDA.

The plugin works indeed - after adding it, the env has :query-params {:service/id 123}

I confirm that @U0522TWDA. Thanks again for your help!!!!!

My pleasure
