• RoR - Associations into practise - forms (View)

  - by NicoJuicy

  I'm learning Ruby on Rails. I'm using some associations (has_many :through, ...) But i'm having some problems with it when i'm combining my views. How exactly do i combine these nested forms? Can i do this with partial forms and where do i have to write extra code for this? I have seen examples only use the "view" and others also edit the controller.... An example would be very nice :-)

• PCRE (recursive) pattern that matches a string containing a correctly parenthesized substring. Why d

  - by Anton N. Petrov

  Well, there are other ways (hmmm... or rather working ways) to do it, but the question is why does this one fail? / \A # start of the string ( # group 1 (?: # group 2 [^()]* # something other than parentheses (greedy) | # or \( (?1) \) # parenthesized group 1 ) # -group 2 + # at least once (greedy) ) # -group 1 \Z # end of the string /x Fails to match a string with nested parentheses: "(())"

• vim trick to align blocks/end keywords in Ruby?

  - by randombits

  Is there a way to simply have my blocks and their closing end keyword align properly with vim? If I have a function which is nested with several conditions, things can start to get ugly fast. Can vim save the day?

• format - Help with printing a table

  - by Michael Kohl

  This question will probably end in a facepalm, but I've tried for a while and am still stuck despite reading through the hyperspec. Basically what I want to do is something like (format t "~{|~{ ~5d~}|~%~}" '((1 23 2 312) (23 456 1 7890))) but instead of hard-coding the 5 it should be calculated from the list (length of longest element from any nested list + 1) to give something like | 1 23 2 312| | 23 456 1 7890| Maybe I'm thinking way too complicated here and there is an easier way to do what I want, but I think I ran myself into a mental corner that I can't get out of.

• SQL: How to order values inside group by

  - by Denis Yaremov

  Consider the following MS SQL Server table: ID | X | Y ------+-------+------- 1 | 1 | 1 2 | 1 | 2 3 | 1 | 3 4 | 2 | 40 5 | 2 | 500 6 | 3 | 1 7 | 3 | 100 8 | 3 | 10 I need to select the ID of the row that has the maximum value of Y grouped by x, i.e: ID | X | Y ------+-------+------- 3 | 1 | 3 5 | 2 | 500 7 | 3 | 100 The query will be nested several times so an optimal performance solution is required... Thank you!

  I have a page (telerik:RadPage) containing few grids and some nested controls and I was wondering how I can: have a particular cell in one of the grid make always visible even during scrolling.

• Maintaining property lists for xCode projects

  - by William Jockusch

  My project currently contains two largish property lists. One is currently 20KB; another is 8KB. So far, I have been maintaining them with xCode's property list editor. This is manageable but also a bit clunky. I am wondering if other people have better ways of doing this? So far, my lists consist of nested arrays of strings. The depth is not uniform.

• Facebook API, export group wall entries

  - by Guy David

  After trying to find a reference to an API/tutorial to such thing, I have come here. I would like to scan a specific group wall, pulling all posts from it, with PHP or C#.

EDIT: If this is not possible, should I consider cURL as an option?

• Generation of abstract class with JCodeModel

  - by SadJokerBY

  I'm trying to generate top-level abstract class with JCodeModel library, but I can't find any way to change class modifiers. It's possible for nested classes (JDefinedClass API provides methods that get modifiers as parameters). But for creation of top level classes I found only JCodeModel API methods that get fully qualified name with or without ClassType (class/interface/annotation/enum) as parameters. Does anybody can suggest me how to change modifiers of JDefinedClass to make it abstract?

• Convert any object to pretty HTML in java

  - by ripper234

  How can I convert a given object (in a generic way with reflection) to pretty printable HTML? What ready made library do you recommend that does this? I need support for simple nested objects (as long as they don't create loops in the object graph). I tried to convert it to JSON, but DefaultPrettyPrinter is not HTML friendly.

• Any Javascript optimization benchmarks?

  - by int3

  I watched Nicholas Zakas' talk, Speed up your Javascript, with some interest. I liked how he benchmarked the various performance improvements created by various optimization techniques, e.g. reducing calls to deeply nested objects, changing loops to count down instead of up, etc. I would like to run these benchmarks myself though, to see exactly how our current browsers are faring. I guess it wouldn't be too difficult to cook up some timed loops, but I'd like to know if there are any existing implementations out there.

• if with multiple conditions, order of execution

  - by markus

  Hi, In an if statement with multiple conditions is second executed if the outcome is clear after checking the first condition? example: if(i>0 && array[i]==0){ } If I swap the conditions a seg fault may occur for negative values of i but this way the memory debugger doesn't find a problem. Can I be sure that this works always or do have have to use nested if statements?

• SVN: Recurisvely add files?

  - by Mark

  I'm trying svn add *.py --force As the documentation suggests, but I know for a fact it's missing files nested in deeper folders. Why? Is there a standard way to do this with other unix commands too? */*.py will nab a few more files, but it's kind of a pain in the butt to do this for every possible depth.

• what is the equivalent of instruct! method in Nokogiri?

  - by Angela

  I'd like to use Nokogiri instead of builder to create an XML document because creating the nested appears easier in Nokogiri (I don't need to create a block for each nest). However, how do I create the equivalent of instruct! using Nokogiri?

  Given an object like this: var obj = { first:{ second:{ third:'hi there' } } }; And a key like this "first.second.third" How can I get the value of the nested object "hi there"? I think maybe the Array.reduce function could help, but not sure.

• C++ Arrays manipulations (python-like operations)

  - by Linai

  Hi Guys, I'm trying to figure out the best C++ library/package for array manipulations in a manner of python. Basically I need a simplicity like this: values = numpy.array(inp.data) idx1 = numpy.where(values > -2.14) idx2 = numpy.where(values < 2.0) res1 = (values[idx1] - diff1)/1000 res1 = (values[idx2] - diff2)*1000 In python it's just 5 lines, but the simplest way in C++ i can think of is quite a number of nested loops. Pls advise..

• Concatenating an array of arrays in Coffeescript

  - by user380572

  Hi everyone, I'm trying to find an elegant way in Coffeescript to merge an array of arrays, so that [[1,2,3],[4,5,6],[7,8,9]] == [1,2,3,4,5,6,7,8,9]. As you might imagine, I need this because I'm generating arrays from a function in a "for in" construct and need to concatenate the resulting nested array: result = (generate_array(x) for x in arr) Is there an elegant way to handle this? Thanks for any pointers!
