• How can I retrieve the instance of an attribute's associated object?

  - by Brandon Linton

  I'm writing a PropertiesMustMatch validation attribute that can take a string property name as a parameter. I'd like it to find the corresponding property by name on that object and do a basic equality comparison. What's the best way to access this through reflection? Also, I checked out the Validation application block in the Enterprise Library and decided its PropertyComparisonValidator was way too intense for what we need.

• How do I use a string as a keyword argument?

  - by Issac Kelly

  Specifically, I'm trying to use a string to arbitrairly filter the ORM. I've tried exec and eval solutions, but I'm running into walls. The code below doesn't work, but it's the best way I know how to explain where I'm trying to go from gblocks.models import Image f = 'image__endswith="jpg"' # Would be scripted in another area, but passed as text <user input> d = Image.objects.filter(f) #for the non-django pythonistas: d = Image.objects.filter(image__endswith="jpg") # would be the non-dynamic equivalent.

• Is it safe to use connection.createStatement().executeQuery(String query);?

  - by javanix

  Is it safe to do connection.createStatement().executeQuery(String query);, or should each java.sql.Statement object be created and closed by "hand" on every use, even if the connection is closed in a finally block? If multiple queries are executed in one method by one connection it would use much less code if instantiating and closing each statement wasn't strictly necessary.

• One-liner javascript to collect values from object graph?

  - by Kevin Pauli

  Given the following object graph: { "children": [ { "child": { "pets": [ { "pet": { "name": "fido" } }, { "pet": { "name": "fluffy" } } ] } }, { "child": { "pets": [ { "pet": { "name": "spike" } } ] } } ] } What would be a nice one-liner (or two) to collect the names of my grandchildren's pets? The result should be ["fido", "fluffy", "spike"] I don't want to write custom methods for this... I'm looking for something like the way jQuery works in selecting dom nodes, where you can just give it a CSS-like path and it collects them up for you. I would expect the expression path to look something like "children child pets pet name"

• A more elegant way to parse a string with ruby regular expression using variable grouping?

  - by i0n

  At the moment I have a regular expression that looks like this: ^(cat|dog|bird){1}(cat|dog|bird)?(cat|dog|bird)?$ It matches at least 1, and at most 3 instances of a long list of words and makes the matching words for each group available via the corresponding variable. Is there a way to revise this so that I can return the result for each word in the string without specifying the number of groups beforehand? ^(cat|dog|bird)+$ works but only returns the last match separately , because there is only one group.

• How to make a macro which gives back a string into the source code?

  - by mystify

  Example: I want to do this: METHODNAME(5) { // do something } which results in: - (void)animationStep5 { // do something } Is there any way to do this? Basically, what I need is a way to generate a real source code string before the program is compiled, so the compiler does see - (void)animationStep5... Or maybe there's something different than a macro, which can help here to auto-generate method names (not at run-time)?

• Can I cache a ManyToOne hibernate object without it being lazy loaded?

  - by Andrew

  @ManyToOne @JoinColumn(name = "play_template_id", table = "team_play_mapping" ) public Play getPlay() { return play; } public void setPlay( Play play ) { this.play = play; } By default, this is eager loading. Can I get it so that it will read the play object from a cache without making it lazy loading? Am I correct that eager loading will force it to do a join query and hence no caching?
