Hi, is it possible to insert a variable function in the pipe operartor?. Something like this: def list_long_trade_fe(schema, function) do long_trades_fe(schema) |> ^function() end

The snippet you have shown does not reference that name, perhaps its a problem on the callsite?

You need to invoke the anonymous function def list_long_trade_fe(schema, function) do long_trades_fe(schema) |> function.() end

@gregvaughn . It is working, however the function needs 1 parameter, and this parameter will be inserted during the pipe. But elixir is asking for the parameter during compilation. undefined function retest_long_select_fields/0 What would be the solution?

The complete functions are like these: In this case, I plan to execute this: list_long_trade_fe(RetestLong, :retest_long_category, retest_long_select_fields) def long_trades_fe(schema, category_atom) do schema |> join(:inner, [lt], er in assoc(lt, :exit_reason)) |> join(:…

list_long_trade_fe(RetestLong, :retest_long_category, &retest_long_select_fields/1)
