%{process_name} as filename in store operator

ml1n

Hello,
I'm trying to use the macro %{process_name}_results as the file name for the store operator but the object saved in the repository ends up being called process_name_results, which is not what I'd expected.
How do I set the object name to be the same as the process name?

The operator setup looks like this:
      <operator activated="true" class="store" compatibility="5.1.001" expanded="true" height="60" name="Store" width="90" x="380" y="300">
        <parameter key="repository_entry" value="%{process_name}_results"/>
      </operator>

Any help gratefully recieved.
M.

Hi ml1n

and welcome to rapidminer (at least it is your first post ).

The correct name of the macro is: process_file, hence

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.1.001">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="5.1.001" expanded="true" name="Process">
    <process expanded="true" height="370" width="614">
      <operator activated="true" class="retrieve" compatibility="5.1.001" expanded="true" height="60" name="Retrieve" width="90" x="112" y="120">
        <parameter key="repository_entry" value="//Samples/data/Iris"/>
      </operator>
      <operator activated="true" class="store" compatibility="5.1.001" expanded="true" height="60" name="Store" width="90" x="311" y="347">
        <parameter key="repository_entry" value="%{process_file}_result"/>
      </operator>
      <connect from_op="Retrieve" from_port="output" to_op="Store" to_port="input"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
    </process>
  </operator>
</process>

worked for me. I can only guess that this is a bug.

@developers: From MacroHandler#getMacro

case PROCESS_NAME:
	String fileName = process.getProcessLocation().getShortName();
	return fileName.substring(0, fileName.lastIndexOf("."))

This snippets work only if the process-name contains an ending. If one add a artificial ending when saving a process, it works. Otherwise not (I have tested it).

hope this was helpful,
