Orquesta's "do" with variable

[argendo]

Hi!
I'm making an orquesta workflow, and i want to call next task via variable, for example, one of my tasks looks like this:

data_fetch:
  action: core.local_sudo
  input:
    cmd: "curl -ks -X GET 'example.com/?q=<%ctx(my_ctx)%>' > ./temp_data.json"
  next:
  - when: <% succeeded() %>
    do: <% ctx(my_variable) %>_flow

where my_variable is a string.

I need it to run different tasks in case of different values of my_variable.
For example: in case of value "first" i want to run first_flow, in case of "second" i want to run second_flow and so on.

Nevertheless stackstorm doesn't want to parse it as a string and move on.

Is it even possible to do such thing or how can i route my flow in case of different values of my_variable?

I think you're looking for this https://docs.stackstorm.com/orquesta/context.html?highlight=dynamic#dynamic-action-execution

Not really, as I understand this one allows to run different actions depends on a dynamic_action variable.
Meanwhile I need to call different tasks with help of variable. For example, I have a variable my_variable which is string with value "task_1" and call task with help of do: so I need this piece of code:
do: <% ctx(my_variable) %>_flow
to be interpreted like this one:
do: task_1_flow
Is it possible? And how exactly?

As far as I know, what you're trying to do is not supported in Orquesta.

Sounds sad :(
Thanks for your help!

So, you have, in your flow, a set of pre-defined tasks that are e.g. first_flow or second_flow etc and you want to branch the execution based on my_variable content. Why not do the evaluation of the variable in the when? for example when: <% succeeded() and ctx().get(my_variable) = 'first' %> do: first_flow etc?

Yep, that sounds like a solution, but i thought there was more pretty solution.
Thanks for your help!
