rails: pass variable to partial

Question

How can I pass a variable to a partial using this code? :

<%= render @performance_indicator.improvement_actions.order("created_at DESC") %>

I want to pass "id=1" and then in _improvement_action, use that variable like:

<%= id %>

EDIT:

This is my improvement_action partial:

You can pass a local variable like so:

render "a_partial", :a_local_variable => whatever, :another_variable => another

Yes, you can, my mistake for misunderstanding your question. I've updated my answer and linked you to a similar question.

I saw that question before and tried like that: <%= render @performance_indicator.improvement_actions, :a_local_variable => 'whatever' %> but dont work, when calling the variable in the partial

It works for me, are attempting to access the local variable as a symbol? (You shouldn't be)

Try this syntax out:

<%= render @performance_indicator.improvement_actions, locals: { local_variable: 1 %>
# then <%= local_variable %>
