问题 I have a method in my application which retrieves the last saved image in my DCIM/Camera folder and copies it to another location on the SD card. I've just tested it on another phone and found that it defaults saving to DCIM/100MEDIA . How am I able to get this path? I ended up writing some code which looped through all the folders in the DCIM folder and retrieved the path of the lastModified() folder. 回答1: Looks like it is manufacturer dependent. In addition to using methods described in

问题 I have the following output which I need to be inserted in the database: Array ( [Test] => Array ( ) [Question] => Array ( [0] => Array ( [category_id] => 3 [answer_style_id] => 2 [Answer] => Array ( [0] => Array ( [capital_category_id] => 14 [correct] => 1 ) ... ... Briefly, each Test hasMany Questions, and each Question hasMany Answer, with each associated model having a foreign key which need to be set by Cake (each Question has a test_id, and each Answer has a question_id). The problem is

问题 I have a UIDocument based app that uses NSFileWrapper s to store data. The 'master' file wrapper contains many additional directory file wrappers, each of which represents a different page of the document. When saving a large document for which only a small proportion of one page has been modified, UIDocument spends a LONG time in the background writing the changes (in writeContents:andAttributes:safelyToURL:forSaveOperation:error: ). Surely it should only be writing out this one small change

问题 I use xcode 3.2.4 on snow leopard. Today when I tried to save a file on my project I get an error message saying: The document "nameOfFile.m" could not be saved. I tried reinstalling xcode but no luck. The file can be edited with other editors and I see the same behavior on all my projects as well as newly created projects. Any ideas? 回答1: Simply by rebooting the computer the issue was fixed. 回答2: We were having this problem in a lab environment where user files are mounted via NFS. The

问题 I'm migrating from SubSonic to EF4. In SubSonic models had a function called Save, if the key of the model was 0 an insert was done, otherwise an update. Is there a way to make a generic Save function like in SubSonic? For exmaple using an extension method? 回答1: Yes but you have to do it yourselves. Try something like this: public interface IEntity { int Id { get; set; } } ... public void SaveOrUpdate<T>(T entity) where T : IEntity { using (var context = new MyContext()) { if (entity.Id == 0)

问题 This is baffling me... When I save my model, the book objects are unchanged. But if I open the invoice and save it again, the changes are made. What am I doing wrong? class Invoice(models.Model): ... books = models.ManyToManyField(Book,blank=True,null=True) ... def save(self, *args, **kwargs): super(Invoice, self).save(*args, **kwargs) for book in self.books.all(): book.quantity -= 1 if book.quantity == 0: book.sold = True; book.save() Edit: I've tried using the post_save signal, but it works
