Reservations and Availability

rubyonrails-talk

Hello...this amounts more to SQL questions rather than Rails specific I guess. I'm new to both.

Basically what I'm trying to do is perform a search for sites which are available for a reservations system. I have a Sites model and I have a Reservations model. Reservations contains columns for checkindate and checkout date. I also created a model for Booking status, which has columns for site_id and date to show which dates and which sites are booked, but I'm not even sure I necessarily need this table if there's a way to query just using the Sites and Reservations models.

The parameters I want to use at this point for the query is to let the user choose a checkindate and a checkout date and I want to return a list of sites which are available.

Any help?

I've done something slightly different, where there was only one site, but that site could have multiple reservations for any given date (and with a varying number of available places on any given day). Effectively, what i did was have an availabilities table, where each row states that the site in question is available on the given time segment (in your case, a single day). You can then say 'give me the sites which have availabilities in the given date range' and then check that the sites returned have all of those availabilities, not just some of them (you may be able to roll that all into one query.
