  • Where to put constants in Rails

    - by Sam
    I have a few constants which are arrays that I don't want to create db's for but I don't know where to store the constants without getting errors. For example CONTAINER_SIZES = [["20 foot"],["40 foot"]] Where can I store this so all models and controller have access to this?

  • In Ant, copy all files from a tree of folders into a single folder?

    - by Sam Washburn
    Is it possible to use Ant to copy all the files (not folders) from a hierarchy of folders into one destination folder? For instance, I have a tree like this: res |-images | |-fg.png | +-bg.png +-sounds +-music.mp3 And I would like a result like this: data |-fg.png |-bg.png +-music.mp3 The way things are named, filename conflicts are not an issue. Is this possible to do with Ant?

  • C#: How to detect . in string and insert a space after it/How to insert space after n chars?

    - by Sam Gentile
    Suppose I have a long string like "4600airportburlingame150anzablvd.burlingamecalifornia94010". My code is breaking on this string. This is UNUSUAL. 99% of entries will NOT have a period. The CSS in the browser wraps IF there are spaces in the string and there isn't any here. How do I detect the period (".") and insert a space directly after it? Remember 99% of strings will NOT have a period in them. The code has to detect if it has a period and if so, do the insertion, otherwise not. If I determine a maximum string length, how do I insert a space at some length? Thanks

  • ZF-Autoloader not working in UnitTests on Ubuntu

    - by Sam
    i got a problem regarding Unit-testing a Zend-Framework application under Ubuntu 12.04. The project-structure is a default zend application whereas the models are defined as the following ./application ./models ./DbTable ./ProjectStatus.php (Application_Model_DbTable_ProjectStatus) ./Mappers ./ProjectStatus.php (Application_Model_Mapper_ProjectStatus) ./ProjectStatus.php (Application_Model_ProjectStatus) The Problem here is with the Zend-specific autoloading. The naming convention here appears that the folder Mappers loads all classes with _Mapper but not _Mappers. This is some internal Zend behavior which is fine so far. On my windows machine the phpunit runs without any Problems, trying to initiate all those classes. On my Ubuntu machine however with jenkins running on it, phpunit fails to find the appropriate classes giving me the following error Fatal error: Class 'Application_Model_Mapper_ProjectStatus' not found in /var/lib/jenkins/jobs/PAM/workspace/tests/application/models/Mapper/ProjectStatusTest.php on line 39 The error appears to really be that the Zend-Autoloader doesn't load from the ubuntu machine, but i can't figure out how or why this works. The question remains of why this is. I think i've double checked every point of contact with the zend autoloading stuff, but i just can't figure this out. I'll paste the - from my point of view relevant snippets - and hope someone of you has any insight to this. Jenkins Snippet for PHPUnit <target name="phpunit" description="Run unit tests with PHPUnit"> <exec executable="phpunit" failonerror="true"> <arg line="--configuration '${basedir}/tests/phpunit.xml' --coverage-clover '${basedir}/build/logs/clover.xml' --coverage-html '${basedir}/build/coverage/.' --log-junit '${basedir}/build/logs/junit.xml'" /> </exec> </target> ./tests/phpunit.xml <phpunit bootstrap="./bootstrap.php"> ... this shouldn't be of relevance ... </phpunit> ./tests/bootstrap.php <?php // Define path to application directory defined('APPLICATION_PATH') || define('APPLICATION_PATH', realpath(dirname(__FILE__) .

  • Why doesn't this piece of php code work?

    - by Sam Gabriel
    Hey guys, I have a mysql database which stores an id for each picture, as well as the picture's url and its thumbnail url. the thumbnail url is something like thumbs/pic.jpg and the page I'm creating has the folder thumbs in the same place it is created. But when I run this piece of code, nothing shows up: <?php ini_set('display_errors', 'On'); error_reporting(E_ALL | E_STRICT); mysql_connect("localhost", "***", "***") or die(mysql_error()); mysql_select_db("pics") or die(mysql_error()); $results = mysql_query("select id from classpics") or die(mysql_error()); $data=mysql_fetch_array($results); foreach($data as $uno) { echo '<td valign="middle" align="center"><a class="neutral" href="../images.php?id=' . $uno['id'] .

  • What should I do if i have a factory method which requires different parameters for different implem

    - by Sam Holder
    I have an interface, IMessage and a class which have several methods for creating different types of message like so: class MessageService { IMessage TypeAMessage(param 1, param 2) IMessage TypeBMessage(param 1, param 2, param 3, param 4) IMessage TypeCMessage(param 1, param 2, param 3) IMessage TypeDMessage(param 1) } I don't want this class to do all the work for creating these messages so it simply delegates to a MessageCreatorFactory which produces an IMessageCreator depending on the type given (an enumeration based on the type of the message TypeA, TypeB, TypeC etc) interface IMessageCreator { IMessage Create(MessageParams params); } So I have 4 implementations of IMessageCreator: TypeAMessageCreator, TypeBMessageCreator, TypeCMessageCreator, TypeDMessageCreator I ok with this except for the fact that because each type requires different parameters I have had to create a MessageParams object which contains 4 properties for the 4 different params, but only some of them are used in each IMessageCreator. Is there an alternative to this? One other thought I had was to have a param array as the parameter in the Create emthod, but this seems even worse as you don't have any idea what the params are. Or to create several overloads of Create in the interface and have some of them throw an exception if they are not suitable for that particular implementation (ie you called a method which needs more params, so you should have called one of the other overloads.) Does this seem ok? Is there a better solution?

  • Making a rewriterule remove .php extension?

    - by Sam
    Hello, I have come up with a rewriterule to to go to any page on my website without typing in the .php extension because it is automatically added to the url. The rule is: RewriteRule ^(\w+)/?$ /$1.php It takes anything you type in my index and adds .php to it, so you can put in http://sampardee.com/index and it pulls up index.php Now my question is how to detect when a user enters http://sampardee.com/index.php and change it to http://sampardee.com/index How could I do so with a rewriterule?

  • Why is PHP discriminating between .php and .abc extensions for caching?

    - by Sam
    There seems to be a problem between how PHP engine handles identical files that differ only in their file extension. Problem: "An If-Modified-Since conditional request returned the full content unchanged." Also, I measured that the .php extension loads much faster than identitcal twin with .xxx extension even though the file contents are identical, and they differ only in their file extension. "HTTP allows clients to make conditional requests to see if a copy that they hold is still valid. Since this response has a Last-Modified header, clients should be able to use an If-Modified-Since request header for validation. RED has done this and found that the resource sends a full response even though it hadn't changed, indicating that it doesn't support Last-Modified validation." homepage ending with .php exact same file, but ending .ast Given: A home.php file is copied as home.xxx and this extension is added to htaccess to recognize it as a PHP file. The .php file listen to the php.ini where freshness is set to 3 hrs, the non .php files have to listen to htaccess where freshness is set to 2 hrs according to: AddType application/x-httpd-php .php .ast .abc .xxx .etc <IfModule mod_headers.c> ExpiresActive On ExpiresDefault M2419200 Header unset ETag FileETag None Header unset Pragma Header set Cache-Control "max-age=2419200" ##### DYNAMIC PAGES <FilesMatch "\\.(ast|php|abc|xxx)$"> ExpiresDefault M7200 Header set Cache-Control "public, max-age=7200" </FilesMatch> </IfModule> So far so good and everything loads, except, the non-php file doesn't cache properly, or it does cache well but doesn't validate well, to be more specific. See images enclosed. Only the non-php file extension causes the error and loads slower. The entire page.php loads faster as somehow all the elements in there then load properly from cache, while the page.abc has the full request returned while it ought to be cached, meaning the entire page is slower. Bottom line: What should be changed, in order eliminate the If-Modified-Since conditional request returning the full content unchanged?

  • function binding and the clone() function - Jquery

    - by Sam Vloeberghs
    Hi I have problems with my keyup binding when cloning an element. Here's the scenario: I have an html markup like this: <tr class="rijbasis"> <td> <input type="text" class="count" /> </td> <td> <span class="cost">10</span> </td> <td> <span class="total">10</span> </td> </tr> I'm binding an keyup function to the input element of my table row like this: $('.rijbasis input').keyup(function(){ var parent = $(this).parent().parent(); $('.total',parent).text(parseInt($('.cost',parent).text()) * parseInt($('.count',parent).val())); } I designed the function like this so I could clone the table row on a onclick event and append it to the tbody: $('.lineadd').click(function(){ $('.contract tbody').append($('.contract tbody tr:last').clone()); $('.contract tbody tr:last input').val("0"); }); This al works , but the keyup function doesnt work on the input elements of the cloned row.. Can anybody help or advice? I hope I was clear enough and I'll be surely adding details if needed to solve this problem. Greetings

  • Rails: render a partial from a plugin

    - by Sam
    I'm getting a missing template error after I try rendering a partial from a plugin. I have included the files with the following: %w{ models controllers helpers views }.each do |dir| path = File.join(File.dirname(__FILE__), 'app', dir) $LOAD_PATH << path ActiveSupport::Dependencies.load_paths << path ActiveSupport::Dependencies.load_once_paths.delete(path) end The Models are getting loaded, but as for other things I'm not sure what's going on. The helpers are not getting loaded too because I just copied the contents of the partial from the plugin instead of the render :partial = and then it came up with a helper error. Question is how to be able to :render :partial = from the views folder in my plugin

  • #nav css affecting all elements in page.

    - by Sam Gabriel
    Hey guys I set up this CSS file to use on the navbar: #nav { background-color: #98bf21; } #nav li { float:left; } #nav li ul{ position: absolute; width: 172px; left: -999em; } #nav li:hover ul{ left: auto; } #nav a:link,a:visited { display:block; width:164px; font-weight:bold; color:white; background-color:#98bf21; text-align:center; padding:4px; text-decoration:none; text-transform:uppercase; } #nav a:hover,a:active { background-color: #7A991A; } And it seems to be affecting all the elements. For example all elements take the styles if the #nav a styles. Is there something I'm missing here? I'm new to web design.

  • Force NCover 1.5.8 to use v4 framework like testdriven.net does?

    - by Sam Holder
    I want to run coverage from the command line, but can't seem to get NCover 1.5.8 to instrument the code. It must be possible as when I run coverage tests with TestDriven.net it works. the difference seems to be that TD.NET is able to get NCover to use framework 4.0 (you get this in the log when it runs : MESSAGE: v4.0.30319) but from the command line I can't make it (I get this in the log : MESSAGE: v2.0.50727) So how can I make NCover play nice with nunit from the commandline, like it does with TD.NET?

  • Strange problem with Random Access Filing in C++

    - by sam
    This is a simple random access filing program . The problem arises where i want to write data randomly. If I write any where in the file the previous records are set to 0. the last 1 which is being entered currently holds the correct value all others =0. This is the code #include <iostream> #include<fstream> #include<string> using namespace std; class name { int id; int pass; public: void writeBlank(); void writedata(); void readdata(); void readall(); int getid() { return id; } int getpass() { return pass; } void setid(int i) { id=i; } void setpass(int p) { pass=p; } }; void name::writeBlank() { name person; person.setid(0); person.setpass(0); int i; ofstream out("pass.txt",ios::binary); if ( !out ) { cout << "File could not be opened." << endl; } for(i=0;i<10;i++) //make 10 records { cout<<"Put pointer is at: "<<out.tellp()<<endl; cout<<"Blank record "<<i<<" is: "<<person.getid()<<" "<<person.getpass()<<" and size: "<<sizeof(person)<<endl; cout<<"Put pointer is at: "<<out.tellp()<<endl; out.write(reinterpret_cast< const char * >(&person),sizeof(name)); } } void name::writedata() { ofstream out("pass.txt",ios::binary|ios::out); name n1; int iD,p; cout<<"ID?"; cin>>iD; n1.setid(iD); cout<<"Enter password"; cin>>p; n1.setpass(p); if (!out ) { cout << "File could not be opened." << endl; } out.seekp((n1.getid()-1)*sizeof(name),ios::beg); //pointer moves to desired location where we have to store password according to its ID(index) cout<<"File pointer is at: "<<out.tellp()<<endl; out.write(reinterpret_cast<const char*> (&n1), sizeof(name)); //write on that pointed location } void name::readall() { name n1; ifstream in("pass.txt",ios::binary); if ( !in ) { cout << "File could not be opened." << endl; } in.read( reinterpret_cast<char *>(&n1), sizeof(name) ); while ( !in.eof() ) { // display record cout<<endl<<"password at this index is:"<<n1.getpass()<<endl; cout<<"File pointer is at: "<<in.tellg()<<endl; // read next from file in.read( reinterpret_cast< char * >(&n1), sizeof(name)); } // end while } void name::readdata() { ifstream in("pass.txt",ios::binary); if ( !in ) { cout << "File could not be opened." << endl; } in.seekg((getid()-1)*sizeof(name)); //pointer moves to desired location where we have to read password according to its ID(index) cout<<"File pointer is at: "<<in.tellg()<<endl; in.read((char* )this,sizeof(name)); //reads from that pointed location cout<<endl<<"password at this index is:"<<getpass()<<endl; } int main() { name n1; cout<<"Enter 0 to write blank records"<<endl; cout<<"Enter 1 for new account"<<endl; cout<<"Enter 2 to login"<<endl; cout<<"Enter 3 to read all"<<endl; cout<<"Enter 9 to exit"<<endl; int option; cin>>option; while(option==0 || option==1 || option==2 || option==3) { if (option == 0) n1.writeBlank(); if(option==1) { /*int iD,p; cout<<"ID?"; cin>>iD; n1.setid(iD); cout<<"Enter password"; cin>>p; n1.setpass(p);*/ n1.writedata(); } int ind; if(option==2) { cout<<"Index?"; cin>>ind; n1.setid(ind); n1.readdata(); } if(option == 3) n1.readall(); cout<<"Enter 0 to write blank records"<<endl; cout<<"Enter 1 for new account"<<endl; cout<<"Enter 2 to login"<<endl; cout<<"Enter 3 to read all"<<endl; cout<<"Enter 9 to exit"<<endl; cin>>option; } } I Cant understand Y the previous records turn 0.
