  • Doctrine: Mixing YAML markup and db manager (navicat) editing?

    - by ropstah
    I think the answer to this question should be: No. However I hope to be corrected. I'd like to edit our database using a mixture of YAML markup + Doctrine createTables() and Navicat editing. Can I maintain the inheritance which is marked up? Example (4 steps, at step 4, Doctrine is in no way able to re-create the inheritance schema... or is it?): Step 1: Create YAML with inheritance --- Entity: columns: username: string(20) password: string(16) created_at: timestamp updated_at: timestamp User: inheritance: extends: Entity type: column_aggregation keyField: type keyValue: 1 Group: inheritance: extends: Entity type: column_aggregation keyField: type keyValue: 2 Step 2: Create tables using Doctrine (and drop/create db if nessecary) Created sql: CREATE TABLE entity (id BIGINT AUTO_INCREMENT, username VARCHAR(20), password VARCHAR(16), created_at DATETIME, updated_at DATETIME, type VARCHAR(255), PRIMARY KEY(id)) ENGINE = INNODB Step 3: Edit table using Navicat Step 4: Refresh YAML file because of 'external' edits...

  • Advice on creating simple web service

    - by London
    Hi all, I want to build simple SOAP web service. So far I've only worked with existing SOAP/Rest services. And now I'd like to create my own, simple one for starters. For example create simple hello + string web service where I provide the string in request from SOAP ui or similar tool. I have Jboss server installed already, what is the "simplest" possible way to achieve this? I realize I need interface, interfaceImpl, and a wsdl file(generated possibly). Does anyone have some useful advice for me ? thank you

  • PHP mysql_real_escape_string() returning `NULL`

    - by DavidYell
    I'm using PHP Version 5.1.6 and trying to escape a query string from my $_GET array. However my script is returning a NULL after it's escaped. It seems that mysql_escape_string() works fine, but it's deprecated, so I don't want to use it. Having checked over the phpinfo() the MySQL lib is all loaded fine from what I can see. Has anyone experienced this kind of thing before? $term = $_GET['q']; var_dump($term); // string(7) "richard" echo "<br />"; $sterm = mysql_real_escape_string($term, $db); var_dump($sterm); // NULL It's very strange to me, I can't imagine why this function wouldn't work.

  • What is a cross-platform way to get the current directory?

    - by rubenvb
    I need a cross-platform way to get the current working directory (yes, getcwd does what I want). I thought this might do the trick: #ifdef _WIN32 #include <direct.h> #define getcwd _getcwd // stupid MSFT "deprecation" warning #elif #include <unistd.h> #endif #include <string> #include <iostream> using namespace std; int main() { string s_cwd(getcwd(NULL,0)); cout << "CWD is: " << s_cwd << endl; } I got this reading: _getcwd at MSDN getcwd at Kernel.org getcwd at Apple.com There should be no memory leaks, and is should work on a Mac as well, correct?

  • How can I get the name of the Lead Owner in a Lead custom formula field?

    - by Jordan Hudson
    I've got an application that reads Lead records from Salesforce via the API and I want to link the Lead Owner field to an attribute in the application. The Lead Owner field doesn't up in the list of available fields but all the custom fields do. So, my first attempt at a solution was to create a custom field that displayed the Lead Owner name. In the SF formula editor, as far as I can tell, it doesn't display the actual data field but instead displays the ID string. Which is pretty meaningless in the context that I need it for. Is there a way that we can get at the data in the object that the ID string references? I have the RED BOX but need the GREEN BOX.

  • In Ruby, is there are better way of selecting a constant (or avoiding the constant altogether) based

    - by Vertis
    Not sure the title fully describes the problem/question I'm trying to ask, sorry. I'm One of my fellow developers has created classes as such: class Widget attr_accessor :model_type ... end and: class ModelType MODEL1 = "model1" MODEL2 = "model2" MODEL3 = "model3" end Now he wants me to convert a retrieved string "MODEL1" to the constant. So that when he is referencing that model elsewhere he can use ModelType::MODEL1. Obviously I've got to convert from the string I'm being given with something like the following: case model_type when 'MODEL1' @model_type = ModelType::MODEL1 ... end I feel like this is clunky, so I'd like to know if there is a better DRYer way of providing this kind of functionality.

  • Taking 2 attributes from XElement to create a dictionary LINQ

    - by AndyC
    I'm trying to take one attribute to use as the key, and another to use as the value. If I use (xDoc is an XDocument object in the example): Dictionary<string, XElement> test = xDoc.Descendants() .Where<XElement>(t => t.Name == "someelement") .ToDictionary<XElement, string>(t => t.Attribute("myattr").Value.ToString()); I get a dictionary with the myattr value as key (which is what I want) but the entire XElement object as the value. What I want to do, is to select a second attribute to set as the value property on each dictionary item, but can't seem to figure that out. Is it possible to do all of this in 1 Linq statement? Curiousity has caught me! Cheers!

  • Extracting two strings from quotations in Java using regex?

    - by user656710
    Hi everyone, I'm new to using patterns and looked everywhere on the internet for an explanation to this problem. Say I have a string: String info = "Data I need to extract is 'here' and 'also here'"; How would I extract the words: here also here without the single quotes using a pattern? This is what I have so far... Pattern p = Pattern.compile("(?<=\').*(?=\')"); But it returns ( here and 'also here ) minus the brackets, that is just for viewing. It skips over the second piece of data and goes straight to the last quote... Thank you!

  • Game doesn't Quit properly

    - by W.K.S
    I have an app that so far consists of two Activities: The Main Menu Activity. The Game Activity The Main Menu Activity contains a button that starts the Game Activity with the following code: public void onClick(View clickedButton) { switch(clickedButton.getId()) { case R.id.buttonPlay: Intent i = new Intent("apple.banana.BouncingBallActivity"); startActivity(i); break; } When the user is done with the Game Activity, he presses the back button. This calls the onPause() method first, which pauses the animation thread of the game. It then calls the onStop() which calls finish() on the activity altogether. The user is returned to the Main Menu activity. The code is outlined below: public class BouncingBallActivity extends Activity{ private BouncingBallView bouncingBallView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); bouncingBallView = new BouncingBallView(this); bouncingBallView.resume(); setContentView(bouncingBallView); } @Override protected void onPause() { super.onPause(); bouncingBallView.pause(); } @Override protected void onResume() { super.onResume(); bouncingBallView.resume(); } @Override protected void onStop() { super.onStop(); this.finish(); } } The problem is that this only works if I launch the application from Eclipse. When I click on the app icon, the game starts from the Game Activity. The main menu activity does not appear. I am not clear about why this happens. It could be something to do with the manifest. I've pasted the relevant portions below: <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <activity android:name=".BouncingBallActivity" android:label="@string/app_name" android:screenOrientation="landscape" > <intent-filter> <action android:name="apple.banana.BouncingBallActivity" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> <activity android:name=".MainMenu" android:label="@string/app_name" android:screenOrientation="portrait" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> I'd really appreciate any help with this. Thanks.

  • C++ vector pointer/reference problem

    - by sub
    Please take a look at this example: #include <iostream> #include <vector> #include <string> using namespace std; class mySubContainer { public: string val; }; class myMainContainer { public: mySubContainer sub; }; void doSomethingWith( myMainContainer &container ) { container.sub.val = "I was modified"; } int main( ) { vector<myMainContainer> vec; /** * Add test data */ myMainContainer tempInst; tempInst.sub.val = "foo"; vec.push_back( tempInst ); tempInst.sub.val = "bar"; vec.push_back( tempInst ); // 1000 lines of random code here int i; int size = vec.size( ); myMainContainer current; for( i = 0; i < size; i ++ ) { cout << i << ": Value before='" << vec.at( i ).sub.val << "'" << endl; current = vec.at( i ); doSomethingWith( current ); cout << i << ": Value after='" << vec.at( i ).sub.val << "'" << endl; } system("pause");//i suck } A hell lot of code for an example, I know. Now so you don't have to spend years thinking about what this [should] do[es]: I have a class myMainContainer which has as its only member an instance of mySubContainer. mySubContainer only has a string val as member. So I create a vector and fill it with some sample data. Now, what I want to do is: Iterate through the vector and make a separate function able to modify the current myMainContainer in the vector. However, the vector remains unchanged as the output tells: 0: Value before='foo' 0: Value after='foo' 1: Value before='bar' 1: Value after='bar' What am I doing wrong? doSomethingWith has to return void, I can't let it return the modified myMainContainer and then just overwrite it in the vector, that's why I tried to pass it by reference as seen in the doSomethingWith definition above.

  • Need help with cURL and POSTing in PHP

    - by alex
    I need to post to a payment gateway. The example PHP script for the gateway simply sets the XML like this curl_setopt($ch, CURLOPT_POSTFIELDS, $xmlRequest); // $xmlRequest is just a string of XML In all of my experience, generally you need to use an array with key/values or a string similar to GET params. I am using Kohana, and tracked down a cURL module. It accepts the POST key/values as an array only. Now, I could ditch the module and throw some cURL straight in, but I am using this module fine all throughout the site, so would prefer to use it here. So, my question is, how does that first one work? Does it just POST the whole thing without any named key? Is there a default key I could use for an array to get the module to work?

  • How to see "anti if" movement and its gaol?

    - by Vijay Shanker
    I have a developer for last 3 years, have been using if-else or if-else if statements a lot in my programing habit. And today, I found This link. One obvious sample i put here public void doSomthing(String target, String object){ //validate requests if(target != null && target.trim().length() < 1){ //invalid request; } //further logic } Now, I have seen this sort of check all over the places, libraries. So, I wanted to have a discussion about the worthiness of such a movement. Please let me know your views.

Please help. Thanks

  • Elegantly Handle Repetitive Property Code in C#

    - by Eric J.
    The language shortcut public string Code { get; set; } saves a bit of typing when defining trivial properties in C#. However, I find myself writing highly repetitive, not-quite-as-trivial property code that still follows a clear pattern e.g. public string Code { get { return code; } set { if (code != value) { code = value; NotifyPropertyChanged("Code"); } } } I can certainly define a Visual Studio snippet to reduce typing. However, if I need to add something to my pattern, I have to go back and change quite a bit of existing code. Is there a more elegant approach? Is a snippet the best way to go?

  • Writing to a file in Unicode

    I am having some problems writing to a file in unicode inside my c program. I am trying to write a unicode Japanese string to a file. When I go to check the file though it is empty. If I try a non-unicode string it works just fine. What am I doing wrong? setlocale(LC_CTYPE, ""); FILE* f; f = _wfopen(COMMON_FILE_PATH,L"w"); fwprintf(f,L"???"); fclose(f); Oh about my system: I am running Windows. And my IDE is Visual Studio 2008.

  • C++: Why does gcc prefer non-const over const when accessing operator[]?

    - by JonasW
    This question might be more appropriately asked regarding C++ in general, but as I am using gcc on linux that's the context. Consider the following program: #include <iostream> #include <map> #include <string> using namespace std; template <typename TKey, typename TValue> class Dictionary{ public: map<TKey, TValue> internal; TValue & operator[](TKey const & key) { cout << "operator[] with key " << key << " called " << endl; return internal[key]; } TValue const & operator[](TKey const & key) const { cout << "operator[] const with key " << key << " called " << endl; return internal.at(key); } }; int main(int argc, char* argv[]) { Dictionary<string, string> dict; dict["1"] = "one"; cout << "first one: " << dict["1"] << endl; return 0; } When executing the program, the output is: operator[] with key 1 called operator[] with key 1 called first one: one What I would like is to have the compiler choose the operator[]const method instead in the second call. The reason is that without having used dict["1"] before, the call to operator[] causes the internal map to create the data that does not exist, even if the only thing I wanted was to do some debugging output, which of course is a fatal application error. The behaviour I am looking for would be something like the C# index operator which has a get and a set operation and where you could throw an exception if the getter tries to access something that doesn't exist: class MyDictionary<TKey, TVal> { private Dictionary<TKey, TVal> dict = new Dictionary<TKey, TVal>(); public TVal this[TKey idx] { get { if(!dict.ContainsKey(idx)) throw KeyNotFoundException("..."); return dict[idx]; } set { dict[idx] = value; } } } Thus, I wonder why the gcc prefers the non-const call over the const call when non-const access is not required.

  • PHP: How do I access child properties from a method in a base object?

    - by Nick
    I'd like for all of my objects to be able to return a JSON string of themselves. So I created a base class for all of my objects to extend, with an AsJSON() method: class BaseObject { public function AsJSON() { $JSON=array(); foreach ($this as $key = $value) { if(is_null($value)) continue; $JSON[$key] = $value; } return json_encode($JSON); } } And then extend my child classes from that: class Package extends BaseObject { ... } So in my code, I expect to do this: $Box = new Package; $Box-SetID('123'); $Box-SetName('12x8x6'); $Box-SetBoxX('12'); $Box-SetBoxY('8'); $Box-SetBoxZ('6'); echo $Box-AsJSON(); But the JSON string it returns only contains the BaseClass's properties, not the child properties. How do I modify my AsJSON() function so that $this refers to the child's properties, not the parent's?

  • Updating .net 4.0 machine.config seems to have no effect

    - by Jon P
    I'm feeling stupid. I've just created my first ASP.net 4.0 site after working my way though over the years from 1.1 upwards. We have several settings at the machine.config level that I need to migrate to the new 4.0 machine.config. I though I had be adding the required connection strings to the connection string section of the following two files: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\machine.config C:\Windows\Microsoft.NET\Framework\v4.0.30319\machine.config When I created a new website in IIS and assigned it to the ASP.net 4.0 Application pool I only get the default LocalSqlServer connection string. I tried editing the name of this in the two files above to indicate which file it was in, but there was no change. Are there machine.config files in other locations I should be looking at?
