Phoenix.View.render_one

You're seeing just the function render_one, go back to Phoenix.View module for more information.
Link to this function

render_one(resource, view, template, assigns \\ %{})

View Source

Renders a single item if not nil.

The following:

render_one user, UserView, "show.html"

is roughly equivalent to:

if user != nil do
  render(UserView, "show.html", user: user)
end

The underlying user is passed to the view and template as :user, which is inflected from the view name. The name of the key in assigns can be customized with the :as option:

render_one user, UserView, "show.html", as: :data

is roughly equivalent to:

if user != nil do
  render(UserView, "show.html", data: user)
end
