Hello,

I need to change mysql database password and setup it on open project but didn’t find config file.

Please check config/database.yml file’s code, It is dynamic code.

<%

require ‘cgi’
require ‘uri’

begin
uri = URI.parse(ENV[“DATABASE_URL”])
rescue URI::InvalidURIError
raise “Invalid DATABASE_URL”
end

raise “No RACK_ENV or RAILS_ENV found” unless ENV[“RAILS_ENV”] || ENV[“RACK_ENV”]

def attribute(name, value, force_string = false)
if value
value_string =
if force_string
‘“’ + value + ’”’
else
value
end
“#{name}: #{value_string}”
else
“”
end
end

adapter = uri.scheme
adapter = “postgresql” if adapter == “postgres”

database = (uri.path || “”).split(“/”)[1]

username = uri.user
password = uri.password
host = uri.host
port = uri.port

params = CGI.parse(uri.query || “”)

%>

<%= ENV[“RAILS_ENV”] || ENV[“RACK_ENV”] %>:
<%= attribute “adapter”, adapter %>
<%= attribute “database”, database %>
<%= attribute “username”, username %>
<%= attribute “password”, password, true %>
<%= attribute “host”, host %>
<%= attribute “port”, port %>

<% params.each do |key, value| >
<%= key : <= value.first %>
< end %>
