问题 I am struggling to update the Jquery file upload plugin so when you upload a file it just overwrites an existing file with the same name instead of renaming it with an upcount. I have applied the change covered in this link: https://github.com/blueimp/jQuery-File-Upload/issues/1965 but I can't seem overwrite this plugin to get this working? there's an existing open question not yet answered here: jQuery File Upload by bluimp, how to replace instead of renaming any guidance on this would be

问题 In Odoo, the quantities of a product are calculated each time the products form is opened. This happens in model product.product ==> function _product_available. This function returns a dictionary called res. Example: res = {8: {'qty_available': 5000.0, 'outgoing_qty': 1778.5, 'virtual_available': 3221.5, 'incoming_qty': 0.0}} Now I want to modify those values. I've managed to do this by coding it directly in the original function _product_available. Since this is not the correct way to do

问题 Lets say you are having a user provide information. Array 1 But not all is required. So you have defaults. Array 2 Does PHP have a function which will overwrite all array values of Array 2 based on if they are supplied in Array 1 , and not empty? 回答1: I think what you are looking for is array_replace_recursive , especially for the case when your "defualts" may be an associative array more than one level deep. $finalArray = array_replace_recursive(array $defaults, array $inputOptions) heres an

问题 I'm attempting to use Python's tarfile module to extract a tar.gz archive. I'd like the extraction to overwrite any target files it they already exist - this is tarfile's normal behaviour. However, I'm hitting a snitch in that some of the files have write-protection on (e.g. chmod 550). The tarfile.extractall() operation actually fails: IOError: [Errno 13] Permission denied '/foo/bar/file' If I try to delete the files from the normal command-line, I can do it, I just need to answer a prompt:

问题 I'm trying to create a basic highscore system for a project I'm working on. The problem I'm having is, although I write the names into my main they just overwrite the previous. Currently I have this: void ManagePoint::saveScore(string Name, int Score) { ofstream newFile("scorefile.txt"); if(newFile.is_open()) { newFile << Name << " " << Score; } else { //You're in trouble now Mr! } newFile.close(); } and for testing I'm adding them like so: runner->saveScore("Robert", 34322); runner-

问题 I have two classes, Field and Background . They look a little bit like this: class Field( object ): def __init__( self, a, b ): self.a = a self.b = b self.field = self.buildField() def buildField( self ): field = [0,0,0] return field class Background( Field ): def __init__( self, a, b, c ): super(Background, self).__init__( a, b ) self.field = self.buildField( c ) def buildField( self, c ): field = [c] return field a, b, c = 0, 1, 2 background = Background( a, b, c ) This error is pointing to

问题 I am writing a program in Java where the output is written to a .txt file. Each time I run the program the file is overwritten. I do not want to use the append switch and add data to the file. I would like to have it so a new file, with the same name, is created each time I run the program. For example, if overflow.txt is the file name, and I run the program three times, the files overflow(1).txt , overflow(2).txt , and overflow(3).txt should be made. How can this be achieved? 回答1: Check if

问题 I have troubles with testing Model in CakePHP 2.0 and it seems the problem is on the model's constructor. public function __construct(){ parent::__construct(); $this->_pagi_cuantos = 2; } Even if I delete all its content, I still getting problems trying to run the test. Mark Story told me: if you have a constructor make sure you're overriding the constructor correctly. Failing to do so will cause errors like this. What do I wrong? 回答1: why don't you look into the core code its open source
