Accessing another database wtih SQL queries - mysql

Question

I am attempting to access another database in my rails app, as well as query that database with SQL statements and return JSON.
The main database and secondary are on the same server running in MySQL. When testing to see if this would simply work as:
The datagbase.yml file:
development:
adapter: mysql2
encoding: utf8
database: onlineportal
username: root
password:
host: 127.0.0.1
port: 3306
socket:
android_mobile_developement:
adapter: mysql2
encoding: utf8
database: androidchatterdatabase
username: root
password:
host: 127.0.0.1
port: 3306
socket:
but then building out the method in the controller:
class RequestsController < ApplicationController
def getActivatedFriends
#results = User.find_by_sql("SELECT
a.id
, a.username
, a.phoneNumber
FROM androidchatterdatabase.users a
WHERE phoneNumber in (8754444444) and
removed = 0 and
is_user = 1;")
respond_to do |format|
format.html
format.json { render json: { friends_match: #results }}
end
end
and calling the route:
localhost:3000/getActivatedFriends/
from the routes:
match '/getActivatedFriends/', to: 'requests#getActivatedFriends', via: 'get'
yields the error:
Missing template requests/getActivatedFriends, application/getActivatedFriends with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}.

Answer 1

While sending the request, send it as local host:3000/getActivatedFriends.json.That way controller will respond to json request. By default it responds to html request.

Answer 2

You can access another database by specifying the database name before the table, such as:
SELECT * FROM onlineportal.table
- or -
SELECT * FROM androidchatterdatabase.table
Is this what you're looking to do? If they're on the same server this syntax would work.
