fetch

问题 I've done a simple service-worker to defer requests that fail for my JS application (following this example) and it works well. But I still have a problem when requests succeed: the requests are done twice. One time normaly and one time by the service-worker due to the fetch() call I guess.

问题 Does Django caching have a method similar to Rails' cache.fetch? (http://api.rubyonrails.org/classes/ActiveSupport/Cache/Store.html#M001023) The rails cache fetch works like: cache.fetch("my_key") { // return what I want to put in my_key if it is empty "some_value" } It's useful because it checks the cache, and returns the value of the cache if it is there. If not, it will store "some_value" in the cache, and then return "some_value". Is there an equivalent of this in Django? If not, what

问题 I'm working on a Drupal 8 site where I have a custom module/block that fetches content from another server and injects it to a div. When a user clicks on a link (like read more) from the injected content, I need to serve the content (full html page) (that gets fetched from the server) without my template's header and footer.

问题 Does the method PDOStatement::fetch() throw an exception on failure, if the PDO error reporting system is set to throw exceptions? E.g. if I set: PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION Do you know such a case? Thank you very much. UPDATE: The method PdoStatement::fetch throws indeed exceptions on failure, instead of FALSE . Such a case is demonstrated in my answer: Simulate a PDO fetch failure situation In conclusion: PDOStatement::fetch returns FALSE if no records are found.
