How to pass values into partials

[tg-mvooges]

I have zero experience with Ruby so maybe this is super simple, but I'm using partials in my docs as that significantly makes things actually maintainable. I have multiple code examples like this (these are minimal, just as example):

 # PHP
  $result = $yourApiClient->get('/api/v1/relation/customers');

 # Javascript
  let xhr = new XMLHttpRequest()
  xhr.open('GET', '/api/v1/relation/customers')
 
# CURL
 curl -I /api/v1/relation/customers

They're mostly the same and I have a lot of exactly that snippet, just with a different url. I want to make this codeblock into a 'simpleCodePreview.md.erb' which I can pass an url into.

According to what i've found only, something like this should work:

<%= render 'partials/relation/customer.md.erb', foo => "bar" %>
<%= render 'partials/relation/customer.md.erb', foo: "bar" %>
<%= partial 'partials/relation/customer.md.erb', foo => "bar" %>
<%= partial 'partials/relation/customer.md.erb', foo: "bar" %>

Using it like this:

<% @foo %>
<%= @foo %>

However, this becomes (something along the lines of):

undefined local variable or method `foo' for ...

Is there any way to use variables in partials/renders?

Current solution:

<%
@method='GET'
@url='/api/v1/catalog/assortments/<UUID>'
%>
<%= partial "partials/snippets/simple-codeblock.md.erb" %>

With the snippet:

```php
$result = $yourApiClient-><%= @method.downcase %>('<%= @uuidUrl %>');
\```

Which ends up in the docs like this:

$result = $yourApiClient->get('givenUrl');
