  • Plural to Singular conversion trouble in Rails Migrations?

    - by Earlz
    Hi, I'm a beginner at Ruby On Rails and am trying to get a migration to work with the name Priorities So, here is the code I use in my migration: class Priorities < ActiveRecord::Migration def self.up create_table :priorities do |t| t.column :name, :string, :null => false, :limit => 32 end Priority.create :name => "Critical" Priority.create :name => "Major" Priority.create :name => "Minor" end def self.down drop_table :priorities end end This results in the following error though: NOTICE: CREATE TABLE will create implicit sequence "priorities_id_seq" for serial column "priorities.id" NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "priorities_pkey" for table "priorities" rake aborted! An error has occurred, this and all later migrations canceled: uninitialized constant Priorities::Priority Is this some problem with turning ies to y for converting something plural to singular?

  • Using SOUNDEX and DIFFERENCE to Standardize Data in SQL Server

    My client wants to standardize address information for existing and future addresses collected for their customers, particularly the street suffixes. The application used to enter and collect address information has the street suffix separated from the address field, but it is a textbox instead of a drop down list therefore things are not standardized. I know there are some options out there to standarize data, but they would like a less expensive alternative. Are there any functions in SQL Server that I can use to standardized data?

  • Base 62 conversion in Python

    - by mikl
    How would you convert an integer to base 62 (like hexadecimal, but with these digits: '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'). I have been trying to find a good Python library for it, but they all seems to be occupied with converting strings. The Python base64 module only accepts strings and turns a single digit into four characters. I was looking for something akin to what URL shorteners use.

  • erroneous Visual C float / double conversion?

    - by RED SOFT ADAIR
    In Visual C++ i wrote the following sample in a C++ program: float f1 = 42.48f; double d1 = 42.48; double d2 = f1; I compiled the program with Visual Studio 2005. In the debugger i see the following values: f1 42.480000 float d1 42.479999999999997 double d2 42.479999542236328 double d1 by my knowledege is OK, but d2 is wrong. The problem occurs as well with /fp=precise as with /fp=strict as with /fp=fast. Whats the problem here? Any hint how to avoid this Problem? This leads to serious numerical problems.

  • Endianness conversion and g++ warnings

    - by SuperBloup
    I've got the following C++ code : template <int isBigEndian, typename val> struct EndiannessConv { inline static val fromLittleEndianToHost( val v ) { union { val outVal __attribute__ ((used)); uint8_t bytes[ sizeof( val ) ] __attribute__ ((used)); } ; outVal = v; std::reverse( &bytes[0], &bytes[ sizeof(val) ] ); return outVal; } inline static void convertArray( val v[], uint32_t size ) { // TODO : find a way to map the array for (uint32_t i = 0; i < size; i++) for (uint32_t i = 0; i < size; i++) v[i] = fromLittleEndianToHost( v[i] ); } }; Which work and has been tested (without the used attributes). When compiling I obtain the following errors from g++ (version 4.4.1) || g++ -Wall -Wextra -O3 -o t t.cc || t.cc: In static member function 'static val EndiannessConv<isBigEndian, val>::fromLittleEndianToHost(val)': t.cc|98| warning: 'used' attribute ignored t.cc|99| warning: 'used' attribute ignored || t.cc: In static member function 'static val EndiannessConv<isBigEndian, val>::fromLittleEndianToHost(val) [with int isBigEndian = 1, val = double]': t.cc|148| instantiated from here t.cc|100| warning: unused variable 'outVal' t.cc|100| warning: unused variable 'bytes' I've tried to use the following code : template <int size, typename valType> struct EndianInverser { /* should not compile */ }; template <typename valType> struct EndianInverser<4, valType> { static inline valType reverseEndianness( const valType &val ) { uint32_t castedVal = *reinterpret_cast<const uint32_t*>( &val ); castedVal = (castedVal & 0x000000FF << (3 * 8)) | (castedVal & 0x0000FF00 << (1 * 8)) | (castedVal & 0x00FF0000 >> (1 * 8)) | (castedVal & 0xFF000000 >> (3 * 8)); return *reinterpret_cast<valType*>( &castedVal ); } }; but it break when enabling optimizations due to the type punning. So, why does my used attribute got ignored? Is there a workaround to convert endianness (I rely on the enum to avoid type punning) in templates?

  • Automated Java to Scala source code conversion?

    - by Alex R
    (Yes I know I can call Java code from Scala; but that is pointless; I want to DELETE the Java code, not keep it around and have to look at it and maintain it forever!) Are there any utilities out there to convert Java source to Scala source? I believe theoretically it should be possible to accomplish with minimal lossage. I have found this but it seems inactive, probably buggy/incomplete... http://sourceforge.net/projects/java2scala/ Any alternatives?

  • UTF-8 conversion

    - by leachianus
    Hey guys, I am grabbing a JSON array and storing it in a NSArray, however it includes JSON encoded UTF-8 strings, for example pass\u00e9 represents passé. I need a way of converting all of these different types of strings into the actual character. I have an entire NSArray to convert. Or I can convert it when it is being displayed, which ever is easiest. I found this chart http://tntluoma.com/sidebars/codes/ is there a convenience method for this or a library I can download? thanks, BTW, there is no way I can find to change the server so I can only fix it on my end...

  • setting up Google Webpage Optimizer where text and conversion pages are the same

    - by Lukich
    Hi. I have a site where both landing and thank you page are index.php page with different content loaded dynamically. As I'm generating the javascript and trying to validate it, it gives me an error saying that JS is not installed on the thank you page, which makes sense, because its content is not loaded yet. I was wondering how I can circumvent this issue? Any suggestions? Thanks! Luka

  • HTML to Text Conversion

    - by JSS
    Internet Explorer has an option to save a web page as a text file, with all the tags removed. I need a way to batch process that stuff for a project at work. Or there any command line utilities or libraries that can do the same thing for me? COM-interop with IE(not my first choice!)? It doesn't have to format exactly like IE, just give me plain text.

  • About conversion of simplexmlobject to array.

    - by Rishi2686
    Hi guys, I tried the way you told but really messing up on some points. I am getting array fields but when it comes to children nodes, i go off the track. here giving single user's simplexml object only : SimpleXMLElement Object ( [users] = SimpleXMLElement Object ( [@attributes] = Array ( [type] = array ) [user] = Array ( [0] = SimpleXMLElement Object ( [id] = 1011 [name] = saroj [location] = SimpleXMLElement Object ( ) [description] = SimpleXMLElement Object ( ) [profile_image_url] = http://a5.example.com/profile_images/img_normal.jpg [url] = SimpleXMLElement Object ( ) [created_at] = Fri Apr 16 17:04:13 +0000 2010 [status] = SimpleXMLElement Object ( [created_at] = Wed May 26 02:56:03 +0000 2008 [id] = 1473 [text] = hi enjoying here! [in_reply_to_user_id] = SimpleXMLElement Object ( ) ) ) To get this into array I am writing code as below : $users = simplexml_load_string($xml); $arr2 = array(); foreach($users->users->user as $user) { $arr1 = array(); foreach($user as $k=>$v) { $arr1[$k] = (string) $v; } $arr2[] = $arr1; } I am getting all the fields as expected from arr2() instead of the status field which contains an array (imp: id & created_at fields repeated), it gives just key as status. While trying differently i get some of the fields of status array too. Please help me on this, i am really trying it from last two days. Help will be greatly appreciated.

  • What's the best way to keep java app data stored redundantly in a file?

    - by Bijan
    If I have systems that are based on realtime data, how can I ensure that all the information that is current is redundantly stored in a file? So that when the program starts again, it uses this information to initialize itself back to where it was when it closed. I know of xstream and HSQLDB. but wasn't sure if this was the best option for data that needs to be a literal carbon copy.

  • C# : Number Conversion Problem

    - by Sayem Ahmed
    Today I faced a strange problem in C#. I have an ASP.NET page where user can enter certain price, quantity etc. I get the price value, convert it to double, then multiply it with 100 and then typecast it to an integer. When the price is "33.30", after converting it to double it remains 33.3 (obviously...), but after multiplying it with 100, it becomes 3329.9999999999995, and when I cast it to integer by applying simple cast operator "(int) (price * 100) ", it becomes 3329. Right now I have no idea why this is happening. So I thought may be you guys can help :) .
