• Rails 2.3: How to turn this SQL statement into a named_scope

  - by randombits

  Having a bit of difficulty figuring out how to create a named_scope from this SQL query: select * from foo where id NOT IN (select foo_id from bar) AND foo.category = ? ORDER BY RAND() LIMIT 1; Category should be variable to change. What's the most efficient way the named_scope can be written for the problem above?

• creating proxy object in groovy

  - by IttayD

  Hi, I am looking for how to write a method that accepts some value and returns a proxy to that value where the underlying value can be retrieved with an accessor: def p = toProxy(1) assert p == 1 assert p * 2 == 2 assert p.underlying == 1 def p2 = toProxy(objWithMethodFoo) p2.foo() p2.underlying.foo() I want to do this per object instance (not for all objects of some class) and without the need to use special 'use' constructs.

• Resharper intellisense confusion

  - by Mystere Man

  Today I had something weird happen in my copy of Resharper 5. I have a class that looks like this: public class Foo { public string Username { get; private set; } public Foo (string userName) { Username = userName; } public void Bar() { DoWork(Username); } public DoWork(string userName) { } } When I start to type DoWork(us I get the following from intellisense: Notice that it's pulling up the constructor argument, and it ends with a colon: userName: What's going on here?

• C++ WCHAR: Cannot allocate an array of constant size 0

  - by Rosarch

  I'm trying to create a WCHAR: LONG bufferSize = foo.bar() + 1; WCHAR wszBaz[bufferSize]; The compiler issues an error: error C2057: expected constant expression error C2466: cannot allocate an array of constant size 0 error C2133: 'wszBaz' unknown size What am I doing wrong? UPDATE: I added const but it still gives the same error: const LONG bufferSize = foo.bar() + 1; WCHAR wszBaz[bufferSize];

• Beginner question about getting reference to cin

  - by John C

  I'm having problems wrapping my head around this. I have a function void foo(istream& input) { input = cin; } This fails (I'm assuming because cin isn't supposed to be "copyable". however, this works void foo(istream& input) { istream& baz = cin; } Is there a reason that I can get a reference to cin in baz but I cannot assign it to input? Thanks

• Dependency Injection and Moqing

  - by rkrauter

  The way I understand it, DI allows you to use an IoC container to do something like If a constructor needs an IFoo, use a concrete class Foo : IFoo. But how is a Mock object using Moq different? Doesn't it also use DI to create a fake Foo? Thanks.

• Deleting document attachments in CouchDb

  - by henrik_lundgren

  In CouchDb's documentation, the described method of deleting document attachments is to send a DELETE call to the attachment's url. However, I have noticed that if you edit the document and remove the attachment stub from the _attachment field, it will not be accessible anymore. If i remove foo.txt from the document below and save to CouchDb it will be gone the next time I access the document: { "_id":"attachment_doc", "_rev":1589456116, "_attachments": { "foo.txt": { "stub":true, "content_type":"text/plain", "length":29 } } } Is the attachment actually deleted on disk or is just the reference to it deleted?

• How to get attributes from parent?

  - by bribon

  Hi all, Let's say we have these classes: class Foo(object): _bar = "" def __init__(self): self.bar = "hello" def getBar(self): return self._bar def setBar(self, bar): self._bar = bar def getAttributes(self): for attr in self.__dict__: print attr bar = property(getBar, setBar) class Child(Foo): def __init__(self): super(Child, self).__init__() self.a = "" self.b = "" if I do something like: child = Child() child.getAttributes() I get all the attributes from parent and child. How could I get the attributes only from the parent? Thanks in advance!

• Python indentation in "empty lines"

  - by niscy

  Which is preferred ("." indicating whitespace)? A) def foo(): x = 1 y = 2 .... if True: bar() B) def foo(): x = 1 y = 2 if True: bar() My intuition would be B (that's also what vim does for me), but I see people using A) all the time. Is it just because most of the editors out there are broken?

• Can this be done in 1 line? [PHP]

  - by Angelo

  Can this be done in 1 line with PHP? Would be awesome if it could: $out = array("foo","bar"); echo $out[0]; Something such as: echo array("foo","bar")[0]; Unfortunately that's not possible. Would it be possible like this? So I can do this for example in 1 line: echo array(rand(1,100), rand(1000,2000))[rand(0,1)];

• Mercurial: include revisions in diff?

  - by David Wolever

  Is there some way to ask Mercurial to show the revisions being diffed in the output? For example: $ hg diff -r trunk:development diff -r 08d51ecf22cf:ff5673e55b9f --git a/foo.c b/foo.c ... Or something similar? I've found that there have been a few times that I've taken a diff (eg, to review), but have later been unable to recreate it because I've forgotten which revisions it was taken against.

  This question about web page 'inclusion' triggered my curiosity. The XML allows you to specify a reference to an 'external' portion. Can you do the same in XHTML, then? XML example: <!ENTITY foo SYSTEM "http://www.mydomain.com/logo.gif" NDATA GIF87A> ... <SOMETHING>&foo;</SOMETHING>

• Assignment in conditional operator

  - by DuoSRX

  I've seen a lot this kind of code recently : if ($foo = $bar->getFoo()) { baz($foo); } Is this considered good or bad practice ? For example, Netbeans IDE give a notice if you use this kind of code : Possible accidental assignment, assignments in conditions should be avoided What do you think ?

• CodeContracts: How to fullfill Require in Ctor using this() call?

  - by mafutrct

  I'm playing around with Microsoft's CodeContracts and encountered a problem I was unable to solve. I've got a class with two constructors: public Foo (public float f) { Contracts.Require(f > 0); } public Foo (int i) : this ((float)i) {} The example is simplified. I don't know how to check the second constructor's f for being 0. Is this even possible with Contracts?

• How do I branch if message.properties-code exists

  - by skurt

  I want to branch if a message-property-code does exist or not. <g:if test="${message(code: 'default.code.foo')}"> true </g:if><g:else> false </g:else> should answer true if there a message property named default.code.foo and false if not. It fails because it answers the code if there is no property for it.
