FYI, There is some overlap in the initial description of this question with a question I asked yesterday, but the question is different.
My app has users who have seasonal products. When a user selects a product, we allow him to also select the product's season. We accomplish this by letting him select a start date and an end date for each product.
We're using date_select to generate two sets of drop-downs: one for the start date and one for the end date.
Including years doesn't make sense for our model. So we're using the option: discard_year => true
When you use discard_year => true, Rails sets a year in the database, it just doesn't appear in the views. Rails sets all the years to either 0001 or 0002 in our app. Yes, we could make it 2009 and 2010 or any other pair. But the point is that we want the months and days to function independent of a particular year. If we used 2009 and 2010, then those dates would be wrong next year because we don't expect these records to be updated every year.
My problem is that we need to dynamically evaluate the availability of products based on their relationship to the current month. For example, assume it's March 15. Regardless of the year, I need a method that can tell me that a product available from October to January is not available right now.
If we were using actual years, this would be pretty easy.
For example, in the products model, I can do this:
def is_available?
(season_start.past? && season_end.future?)
end
I can also evaluate a start_date and an end_date against current_date
However, in setup I've described above where we have arbitrary years that only make sense relative to each other, these methods don't work. For example, is_available? would return false for all my products because their end date is in the year 0001 or 0002.
What I need is a method just like the ones I used as examples above, except that they evaluate against current_month instead of current_date, and past? and future months instead of years.
I have no idea how to do this or whether Rails has any built in functionality that could help. I've gone through all the date and time methods/helpers in the API docs, but I'm not seeing anything equivalent to what I'm describing.
Thanks.
