First of all, I’ll apologize because this is going to be more of a
general setup question rather than a specific coding question. I’m
relatively new to Rails and I’ve never built a web service before. So,
here’s my problem:
I’m building 3 new applications that all relate to one another, but can
also be stand-alone. Meaning a user can register with each one
individually. However, one of the requirements is to only have one
login. So once a user registers with any of the 3 applications, they
are then in the system and can use the same username/password they’ve
Now, it seems to me that this is a perfect situation to have a web
service to manage users. If not, you can stop here and possibly explain
a better solution? (Note: I don’t want to use openID).
Here are the things I would want to do in the web service:
- Register a user, saving all information to the webservice (but only
email and password will be required).
- Login a user, returning their user_id to be held in session. This
would require a call to the webservice to verify that the user exists,
and if not, prompt them to register.
Those are the absolute minimum requirements. Now, what else should I
have? I want to keep track of last logins and login attempts as well,
so I was thinking about having the following tables: Users, Audits,
Logs. Users is obvious, Audits would keep track of logins and attempts,
Logs would record eroneous errors (or should I use a flat file for
If you’ve made it this far, and that sounds reasonable, what type of
code needs to be written to connect to the webservice? I’m not
completely sure I know how it works. Would I have a method like
“verify_user(email, pwd)” that would return xml data if the user exists,
and an error code if they don’t?
I’ll stop here for now, and ask more coding-type questions once I figure
out the general idea of how to accomplish this. If someone can explain
the basics of an implementation to have one way to track multiple users
across 3 applications, I’m open to suggestions.
Again, I’m sorry this is kind of general, but I didn’t know which forum
would be most appropriate. Thanks for any help on this matter.
