  • Checking ActiveRecord Associations in RSpec.

    - by alokswain
    I am learning how to write test cases using Rspec. I have a simple Post Comments Scaffold where a Post can have many Comments. I am testing this using Rspec. How should i go about checking for Post :has_many :comments. Should I stub Post.comments method and then check this with by returning a mock object of array of comment objects? Is testing for AR associations really required ?

  • Echo items with value of three

    - by user342391
    I need to echo all items in my row that have the value of three. If a field has the value of three I then need to echo the 'name' and 'description' on that row. This is what I have so far $result = mysql_query($query1) or die(mysql_error()); while ($row = mysql_fetch_array($result)) { echo $row['status']; } I need to write 'if $row[`status´ == 3 echo 'description' 'name' else echo 'no current staus' I hope I made some sense because I am seriously confused

  • Special chars in Amazon S3 keys?

    - by Martin
    Is it possible to have special characters like åäö in the key? If i urlencode the key before storing it works, but i cant really find a way to access the object. If i write åäö in the url i get access denied (like i get if the object is not found). If i urlencode the url i paste in the browser i get "InvalidURICouldn't parse the specified URI". Is there some way to do this?

  • Change library load order at run time (like LD_PRELOAD but during execution)

    - by tylerl
    How do I change the library a function loads from during run time? For example, say I want to replace the standard printf function with something new, I can write my own version and compile it into a shared library, then put "LD_PRELOAD=/my/library.so" in the environment before running my executable. But let's say that instead, I want to change that linkage from within the program itself. Surely that must be possible... right?

  • Python string formatting too slow

    - by wich
    I use the following code to log a map, it is fast when it only contains zeroes, but as soon as there is actual data in the map it becomes unbearably slow... Is there any way to do this faster? log_file = open('testfile', 'w') for i, x in ((i, start + i * interval) for i in range(length)): log_file.write('%-5d %8.3f %13g %13g %13g %13g %13g %13g\n' % (i, x, map[0][i], map[1][i], map[2][i], map[3][i], map[4][i], map[5][i]))

  • In Python, can I single line a for loop over iterator with an IF filter?

    - by Tal Weiss
    Silly question: I have a simple for loop followed by a simple if statement: for airport in airports: if airport.is_important: and I was wondering if I can write this as a single line somehow. So, yes, I can do this: for airport in (airport for airport in airports if airport.is_important): but it reads so silly and redundant ("for airport in airport for airport in airports..."). Is there a better way?

  • How can I parse through a texutre in DirectX? (IDirect3DTexture9*)

    - by meds
    I've been trying to figure out how to parse textures in directx for two reasons: to write my own texture format and to manipulate data in existing IDirect3DTexture9 type textures. I've been looking at the IDirect3DTexture9::LockRect() function but I'm unsure how it works, are the void* pBits I get out of it in D3DLOCKED_RECT the data in the texture? Does that mean I can read it in by converting it to D3DXCOLOR or something? Really not sure where to go, any help would be appreciated!

  • FileStream to save file then immediately unlock in .NET ?

    - by aron
    I have this code that saves a pdf file. FileStream fs = new FileStream(SaveLocation, FileMode.Create); fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length); fs.Flush(); fs.Close(); It works fine. However sometimes it does not release the lock right away and that causes file locking exceptions with functions run after this one run. Is there a ideal way to release the file lock right after the fs.Close()

  • Play animation (storyboard) backwards

    - by drasto
    Is there a simple way to play some StoryBoad backward (reversed) ? As there is a method Storyboard.Begin() I would expect that there is some method like "Storyboard.BeginReversed()" but I cannot find it. If there is no way to play an animation backwards that I have to write for most of my animations complementary animations. That smells bad to me (code duplication of some kind). Basically I just animate a Grid that shows and than hides.

  • Complex JavaScript. What called me?

    - by tyndall
    Project I'm working on uses jQuery. I have a series of Ajax calls being made that load() other HTML fragments which in turn load() other fragments. The whole thing is confusing. I didn't write the code. Is there any tool which will allow me to walk the callstack so I can figure what is calling a method? any browser tools that would help me figure this out?

  • Dynamic sql vs stored procedures - pros and cons?

    - by skyeagle
    I have read many strong views (both for and against) SPs or DS. I am writing a query engine in C++ (mySQL backend for now, though I may decide to go with a C++ ORM). I cant decide whether to write a SP, or to dynamically creat the SQL and send the query to the db engine.# Any tips on how to decide?
