Normalizes the arguments and passes it on to find_templates.

# File lib/action_view/template/resolver.rb, line 150
def find_all(name, prefix = nil, partial = false, details = {}, key = nil, locals = [])
  locals = locals.map(&:to_s).sort!.freeze

Handles templates caching. If a key is given and caching is on always check the cache before hitting the resolver. Otherwise, it always hits the resolver but if the key is present, check if the resolver is fresher before returning it.

# File lib/action_view/template/resolver.rb, line 180
def cached(key, path_info, details, locals)
  name, prefix, partial = path_info

  if key
    @cache.cache(key, name, prefix, partial, locals) do
      yield
    end
  else
    yield
  end
end

find_templates(name, prefix, partial, details, locals = []) click to toggle source

This is what child classes implement. No defaults are needed because Resolver guarantees that the arguments are present and normalized.

# File lib/action_view/template/resolver.rb, line 172
def find_templates(name, prefix, partial, details, locals = [])
  raise NotImplementedError, "Subclasses must implement a find_templates(name, prefix, partial, details, locals = []) method"
end
