Normalizes the arguments and passes it on to find_templates.

Private Instance Methods
build_path(name, prefix, partial)

Helpers that builds a path. Useful for building virtual paths.
# File lib/action_view/template/resolver.rb, line 172 def build_path(name, prefix, partial) Path.build(name, prefix, partial) end
cached(key, path_info, details, locals) { || ... }

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 locals = locals.map(&:to_s).sort! if key @cache.cache(key, name, prefix, partial, locals) do decorate(yield, path_info, details, locals) end else decorate(yield, path_info, details, locals) end end
decorate(templates, path_info, details, locals)

Ensures all the resolver information is set in the template.
# File lib/action_view/template/resolver.rb, line 194 def decorate(templates, path_info, details, locals) cached = nil templates.each do |t| t.locals = locals t.formats = details[:formats] || [:html] if t.formats.empty? t.variants = details[:variants] || [] if t.variants.empty? t.virtual_path ||= (cached ||= build_path(*path_info)) end end
find_templates(name, prefix, partial, details, outside_app_allowed = false)

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 167 def find_templates(name, prefix, partial, details, outside_app_allowed = false) raise NotImplementedError, "Subclasses must implement a find_templates(name, prefix, partial, details, outside_app_allowed = false) method" end
