How to Dump Workflows
How to Dump Workflows¶
To help you debug your workflows, you can dump a representation of your workflow
with the use of a
DumperInterface. Use the
GraphvizDumper to create a
PNG or SVG image of the workflow defined above:
// dump-graph.php $dumper = new GraphvizDumper(); echo $dumper->dump($definition);
1 2 3 4
$ php dump-graph.php | dot -Tsvg -o graph.svg # run this command if you prefer PNG images: # $ php dump-graph.php | dot -Tpng -o graph.png
The result will look like this:
Inside a Symfony application, you can dump the dot file with the
$ php bin/console workflow:dump name | dot -Tsvg -o graph.svg
dot command is part of Graphviz. You can download it and read
more about it on Graphviz.org.
