Question

ORM settings in Coldfusion application.cfc run before anything else runs (onapplicationstart, etc). So how do you set a dynamic datasource (code before the ORM init) in application.cfc? we can set it after and it re-points the ORM to a dynamic datasource, but that requires that the hardcoded datasource must be valid as well. This is tenuous at best.

Here is an example:

<cfscript>
this.name = "someapp_#hash(cgi.http_host)#";
this.ormenabled = "true";
this.ormsettings = { cfclocation = "config/definitions", eventhandling = "true",datasource="STATICDATASOURCE" };
</cfscript>

If it’s not specified in application.cfc scope then you get errors like “ORM is not configured for the current application.”

We need to be able to get the datasource from a text file on the server.

Answer 1

this.datasource="YourDatasourceName";

Well, if you wanted to store a file, for this example we’ll call it “datasource.xml” consisting of:

<dataSourceName>Name goes here</dataSourceName>

You can read it in with:

dataFile = fileRead("pathToFile/datasource.xml");
data = xmlParse(dataFile);
dataSourceName = data.dataSourceName.xmlText;

this.datasource=dataSourceName;
