rails convert a string back to date format

In rails I want to check the following condition:

student.bday >= @from_date and student.bday <= @to_date

where @from_date and @to_date are determined as:

t = Date.today
@from_date = t.at_beginning_of_week.strftime("%d %b")
@to_date = t.at_end_of_week.strftime("%d %b")

But in the database student.bday is saved as a string (eg: 17 Aug). Its not a date field. How can I convert this string (17 Aug) into ("%d %b")format or convert to 17 08 or something like that so that I could check the above condition? Any suggestions?

Date.parse("17 Aug")
# Sun, 17 Aug 2014

You may want to bring everything to the same year for the comparison to be effective, just to make sure.

bday = Date.parse("#{student.bday} #{Date.today.strftime('%Y')}")

But default behaviour is to add current year, so this is just redundant...

Better still, provide a parse model, for parsing to be most accurate

bday = Date.strptime("#{student.bday} #{Date.today.strftime('%Y')}",'%d %b %Y')
# %d: day of month, %b: Short month, %Y: Year

You can convert your student.bday into the required format as:

Date.parse(student.bday).strftime("%d %m")

This will give the output as "17 08"
