namespaces

问题 I am facing a very unusual problem. I've registered the namespace myapp using app_name in my main project's urls.py file like this: app_name = 'myapp' I'm writing a view where the user registers and is redirected to the homepage. However, when I'm using the redirect function in myapp's views.py file like this: return redirect('myapp: index') I'm getting the following error after clicking the registration form's submit button: NoReverseMatch at / 'myapp' is not a registered namespace I tired

问题 I'm getting a "too few arguments in function call" while trying to call a function from another namespace that happens to have the same name with the function it's being called from. Here, you can see what I mean: namespace doa::texture { using namespace internal::texture; Texture* const CreateTexture(const std::string& name, const std::string& pathToTextureImage) { //below should call internal::texture::CreateTexture, not doa::texture::CreateTexture Texture* texture{ CreateTexture

问题 I am trying to access some Nodes in my XML File, but I cant get it working because i probably don't understand XML-Namepsaces in Delphi. <gesmes:Envelope xmlns:gesmes="http://www.gesmes.org/xml/2002-08-01" xmlns="http://www.ecb.int/vocabulary/2002-08-01/eurofxref"> <gesmes:subject>Reference rates</gesmes:subject> <gesmes:Sender> <gesmes:name>European Central Bank</gesmes:name> </gesmes:Sender> <Cube> <Cube time="2018-01-18"> <Cube currency="USD" rate="1.2235"/> <Cube currency="JPY" rate="136

问题 I have this: class MyClass: """A simple example class""" i = 12345 def f(self): print i # self.i will work just fine return 'hello world' When I do: >>> x = MyClass() >>> >>> x.f() I get an error, as expected. My question is: Why do I get the error? Why is there no namespace between the namespace of the function(or method) definition and the global namespace of the module containing the class? Is there any other way to reference i inside f in this case other than using self? 回答1: You've got

问题 This question already has an answer here : Nested class is not defined in itself (1 answer) Closed 3 years ago . I have a class defined inside another class like this.

问题 I'm trying to make a Sublime Text-snippet that inserts a PHP boilerplate class, in the lines of: <?php namespace Namespace\Subnamespace; class TestClass { public function __construct() { //code... } } When using PHP-FIG standards(or similar), both the namespace and classname can be obtained from the path of the file. The file in the example above would be placed in /Users/Projects/Whatever/src/Namespace/Subnamespace/TestClass.php . This is what I have so far: <snippet> <content><![CDATA[ <

问题 With the XmlSerializer I can have my members in different namespaces to the parent type. Can I do the same thing with DataContractSerializer ?

问题 I encountered a peculiar difference in xslt behavior when the root element has a default namespace attribute as opposed to when it does not. I am wondering why this difference occurs. The XML input is <root> <content>xxx</content> </root> When the following transformation is applied <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" indent="yes"/> <xsl:template match="/"> <root> <xsl:apply-templates/>

问题 From other posts, it appears that if you have namespaces defined and want to dynamically create an object in another namespace, you have to construct a string and use that in the new call. However, I'm getting a weird behavior. It appears that this method does not work going across namespaces. User.php: namespace application\models; class User { public function hello() { echo "Hello from User!"; } } Controller.php: namespace application\controllers; use application\models; require('User.php')
