Hi  
This is a database implementation question…I am currently using  
mydbname\_development  
mydbname\_test  
mydbname\_production in database.yml file…So now my requirement is  
suppose two (for example) companies use my application…And my purpose  
is to dynamically select separate databases for these two companies…For  
example company 1 uses say  
company1\_develeopment  
company1\_test  
company1\_production and company 2 uses  
company2\_develeopment  
company2\_test  
company2\_production and so on …So can I change db settings at  
database.yml dynamically( Am I right?)…Or is there any other  
method?Please help

Thanks in advance
