How to set custom user-agent for Mechanize in Rails

I know you have a set of pre-defined aliases you can use by setting agent.user_agent_alias = 'Linux Mozilla' for instance, but what if I want to set my own user agent, as I'm writing a web crawler and want to identify it, for the sites I'm indexing's sake. Just like Googlebot.

There seems to be a user_agent method, but I can't seem to find any documentation about it's function.

You can set the user agent from an alias

a =
a.user_agent_alias = 'Mac Safari'

Available aliases are stored in the AGENT_ALIASES constant.

p Mechanize::AGENT_ALIASES

Otherwise, use #user_agent to set your custom user agent.

a =
a.user_agent = 'Custom agent'
