I want to know if there is a way to parse a received email.
For example, someone sends me the following email:
{
product: "x_product",
quantity: "1",
price: "15",
}
What I want is a way to get this information and insert it in the database I know there is a method in ActionMailer::Base called receive. Is this the correct approach? How to parse this?
Yes this is the correct approach, just google "receive mails with ruby on rails" - there are plenty of tutorials to guide you.
The parsing depends on the kind of data you are about to receive. This looks like JSON, so you'd simply let a JSON parser do the work and it will give you a proper Ruby data structure. The rest (putting it into a DB) can be handled by a model.
It would look a bit like this:
class MailReceiver < ActionMailer::Base
def self.receive(message)
# depending on your Rails version you can use either TMail or Mail to parse the raw mail
mail = TMail::Mail.parse(message)
# parse the JSON
my_data = ActiveSupport::JSON.decode(mail.body)
# create something with the data
MyModel.create(my_data)
end
end
I did not cover the actual fetching of the mails from a mailbox. Again: google it, there are tons of tutorials out there. Have a look at Fetcher , which has always served me well.
