yii - Using Multiple Database Connection Not Working For Extension -

-

I'm making many database connections using the tutorial. The code is working fine in the model but the problem is that I am using an extension where I have the Yi :: app () - gt; & Gt; Db; Here I am getting the exception property "CWebApplication.dbadvert" is not defined. The extension of the extension has been enhanced by the CExtController. Please help.

In the example you are setting dbadvert for custom code records class RActiveRecord , not for web application.

If you would like it to be Yii :: app () -> gt; Dbadvert , you will need to set it up in your config.php section 

  'dbadvert' = & gt; Array ('class' = & gt; 'CDbConnection' * parameter * *),   
  UPD   
 A wrapper component for you You can create CDbConnection, which you want in any way to change the connection string and put it as a webapp component.  
  & lt ;? Php class CMultiuserDatabaseConnection CaptureComment {public function __call ($ name, $ params) {$ db = $ this- & gt; Db; Return call_user_func_array (($ db, $ name), $ params); } Public $ dbConnectionClass = 'CDbConnection'; Public $ connection = zero; Public $ default configuration = null; Public function getDatabaseConfiguration ($ user) {if (! $ This-> Connection) {Return Array (); } Return_key_exists ($ user, $ this-> connection)? $ This- & gt; Connection [$ user]: $ this- & gt; Default configuration; } Public function getDb () {$ user = Yii :: app () - & gt; the user; If ($ user- & gt; isGuest) {return false; } $ Username = $ user- & gt; Name; $ Config = $ this- & gt; getDatabaseConfiguration ($ username); If (! $ Config) {return false; } $ Dsn = array_key_exists ('dsn', $ config)? $ Config ['dsn']: Faucet; If (! $ DSN) {return false; } $ User = array_key_exists ('user', $ config)? $ Config ['user']: faucet; $ Password = array_key_exists ('password', $ config)? $ Config ['password']: zero; $ Result = new $ this- & gt; DbConnectionClass ($ dsn, $ user, $ password); Return result; }}   
 This is a raw example of the component, which you can set as your 'DB' component, and then you can set the 'Connection' to store the per-user configuration The way to get the option:  
  'component' = & gt; Array (... 'db' = & gt; array ('class' = & gt; "CMultiuserDatabaseConnection", 'connection' = & gt; array ("first user name" => array = (// just other db Configuration here, for user-one), "second-user-name" = & gt; array (// just for other DB configuration herer, for two users), ...), 'default configuration' = & gt; The array (/ * * goes to the configuration for all other users, which were not specified in the connection. * /),), ...),

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the
