symfony - whats the point of using the @Method annotation -


Route method: A shortcut to specify the permitted HTTP method for the path is the @ method annotation. To use it, import the method annotation namespace: 

  Sensio \ Bundle \ FrameworkExtraBundle \ Configuration \ Route; Use Sensio \ Bundle \ FrameworkExtraBundle \ Configuration \ Method; / ** * Root ("/ blog") * / Class PostController Implementing the Administrator {@ ** (@ / "{ID}") * @ method ({"GET", "POST" }} / Public Function Edit Action ($ ID) {}}   
 I have seen many developers that the method is limited to limiting or posting, but since the controller By default both allow, why do developers want to restrict it to only one method? Is this some safety measure? And if so, what type of attack will protect you?  
 
 
 First of all, there are many ways available, not only received and posted  
 I do not think this is a security reason, it is a matter of respecting standards (for example). I personally use different methods for many behaviors. For me, see the version, and apply the version. 
 There are two different behaviors for a single URL even if the reaction  results  can not change at the end, the behavior at the controller level is different.  
 I think this is a matter of choice of person, I like to watch    / ** * @ Root ("/ edit") * @ method ( {"GET"}) * @template * / Public function editing action () {$ obj = new Foo; $ Obj- & gt; SetBaz ($ this- & gt; container- & gt; getParameter ('default_baz')); $ Type = new FooType; $ Form = $ this- & gt; Createform ($ type, $ obj, array ('action' => $ this-> generationalUrl ('acme_foo_bar_doedit'), 'method' = & gt; 'PUT')); Returns array ('form' = & gt; $ form-> createView ()); }   
 It is very clear what it does. It only instances the form you need, no user input is processed. 
 Now, you can add your action to process the version by adding another method  (@ / "*" @ route ("/ edit") * @ method ({"PUT" }) @ Template ("AcmeFooBundle: bar: edit.html.twig") * / Public Function doEditAction (Request $ request) {$ obj = new Foo; $ Type = new FooType; $ form = $ this- & gt; Createform ($ type, $ obj, array ('action' => $ this-> generationalUrl ('acme_foo_bar_doedit'), 'method' = & gt; 'PUT')); $ Form & gt; handleRequest ($ request); If ($ form-> isValid ()) {// $ obj} play with return array ('form' = & gt; $ form-> createView ()); }   
 It's easy, and can be easily accessed anywhere in your app (instead of the default version page)

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
