How to get struct in array

@shahryarjb: Sorry, but I don’t know few things:

  1. What’s value of category_alias variable - "jsjsjs" ?
  2. What’s value of group_acl variable - root list from gist ?
  3. fetch_posts_by_category_alias function body

If I assumed correctly (about your variables) then:

def load_posts_by_category_alias(category_alias, group_acl) do
  group_acl
  |> Enum.find(& &1.seo_alias_link == category_alias)
  |> Map.fetch!(:cms_post)
  |> Enum.map(& &1.title)
end
