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

i cant pass a created local variable ? – terrorista Mar 31 '16 at 02:13
Yes, you can, my mistake for misunderstanding your question. I've updated my answer and linked you to a similar question. – Mar 31 '16 at 02:16
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 – terrorista Mar 31 '16 at 02:25
It works for me, are attempting to access the local variable as a symbol? (You shouldn't be) – Mar 31 '16 at 02:27
im trying to access like this: `<%= a_local_variable %>` – terrorista Mar 31 '16 at 02:29
If you try <%= local_variable.nil? %> what shows up in your page? – Mar 31 '16 at 02:31
undefined local variable or method `local_variable' for #<# – terrorista Mar 31 '16 at 02:32
The code I posted was an example, when copying and pasting you need to replace "local_variable" with the name of your real local variable. – Mar 31 '16 at 02:33
i rendered like this: `<%= render @performance_indicator.improvement_actions, :local_variable => '1' %>` and called the variable like this: `<%= local_variable %>` – terrorista Mar 31 '16 at 02:35

Try this syntax out:

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