php - CakePHP: associating two models using different databases? -

-

I have two models, plants and amps, which have many relationships and I have configured them to join and The query is correct to get data for each, but the problem is that the plant and the AMP are on different databases. I am on the database database 1, Plant is on Database 2. Because of this, they do not query properly to join; The included table is only on database 1.

When the plant tries to use the table of joining, then it is querying Database 2, which does not have this data.

It is for the Association Emp Plant. 

  is $ var and Belongsomani = array ('Plant' => Array ('className' = & gt; 'Plant', 'JoinTable' => 'emp_plant', 'ForeignKey' = & Gt; 'Employee_ID', 'Association Leading' = & gt; 'LocationID', 'Unique' => True, 'Terms' =>, '',));   
  Update : I tried to set a "Finder query" attribute to allow the table to join, but I do not know how to use a raw SQL Queries are given, such as allowing the dynamically use of IDs for the model's  example  rather than a predefined value.  
 I [Plant] Join [DB] from [Plant], from  
  Selection]. [DBO]. [Emplant] AS [Emplant] on [[employee_id] = ** 4 ** and [amplant]. [ID] = [Plant]. [Location ID]]   
 Give me the right data for an employee  a , but I do not know how to make this finder dynamic query should be a way to work for it.   
 
 
 Try  
  Var $ useDbConfig = 'optional';   
 In your model class.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
