Setting result of find to variable, which has variables within it


Setting result of find to variable, which has variables within it

around this issue As seen in comments, the problem lies in using ${$var} instead of just ${var}:
code :
PART=$(find /mnt/hgfs/Audio\ Log/ -type f -name "LoggerAudio ${$DAY}-${$MO}-${$YR}\ ${H}*" | wc -l)
                                                               ^       ^      ^
PART=$(find /mnt/hgfs/Audio\ Log/ -type f -name "LoggerAudio ${DAY}-${MO}-${YR}\ ${H}*" | wc -l)

CakePHP find all not setting values to variables. All other find functions working

CakePHP find all not setting values to variables. All other find functions working

I wish this helpful for you After several hours of tracking the data until we figured out where it was being lost, we found that the problem was some of the data in the database. It was encoded and it was causing a while statement in the core cake files to reset when it encountered said data. The solution was to alter Config/database.php as such: class DATABASE_CONFIG {
code :
    public $default = array(
            'datasource' => 'Database/Mysql',
            'persistent' => false,
            'host' => 'localhost',
            'login' => 'login',
            'password' => 'Password',
            'database' => 'database',
            'prefix' => '',
            'encoding' => 'utf8',//this line allows the database to read utf8 data.
    );

this one helps. Typically, it is good practice for your class variables to be private, which means they can't be set except by methods and constructors of the class the variables belong to. The advantage of using methods to set variables (these methods are referred to as setters) is that you can provide validation logic within the method.
For example, if you have a variable within your class that is supposed to represent the hour of the day, you will only want it to hold a value 0 to 23. Your setter can throw an exception any time the user of the method attempts to set the variable to anything outside this range.

help you fix your problem Your $.ajax() call is asynchronous. The results of the call are not available until the HTTP response is received by the browser.
Put your console.log() calls inside the .then() function.

wish help you to fix your issue the console.log is outside the callback. so that it's undefined. Put it in the callback.
code :
var collection = req.db.get('myCollection');
collection.find( { foo: 'bar' },{
  fields : { myTargetField: 1, _id: 0},
  limit : 1,
  sort : {$natural : -1}
}
, function(err, doc) {
    if (err) {
      console.log(err);
    }
    var variableIWantToSet = doc[0].myTargetField;
    console.log(variableIWantToSet);
});
 //The callback function will be call after the mongodb response right value.
var callback = function(err, doc) {
    if (err) {
      console.log(err);
    }
    variableIWantToSet = doc[0].myTargetField;
    console.log(variableIWantToSet); // return doc[0].myTargetField;
}; 

var variableIWantToSet;

var collection = req.db.get('myCollection');
collection.find( { foo: 'bar' },{
  fields : { myTargetField: 1, _id: 0},
  limit : 1,
  sort : {$natural : -1}
}
, callback);
 console.log(variableIWantToSet); // return undefined;

wish helps you I don't think its necessary to add everything into path.Just add the JAVA_HOME , ANDROID_HOME and ANT_HOME to path and point out the corresponding bin directory as:
For android studio
code :
1.export ANDROID_HOME=/path/to/android/studio
2.export PATH=$PATH:$ANDROID_HOME/bin
1.JAVA_HOME=/path/to/jdk
2.JRE_HOME=$JAVA_HOME/jre
3.PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
4.export JAVA_HOME
5.export JRE_HOME
6.export PATH
