A little new to Rails here so really appreciate all the help!
I have a form where I get the user to input 2 date fields. I want to calculate the number of days between these 2 dates. How would I go about doing this? Do I create a new method in the controller to calculate this?
Also, after I calculate this number, I want to display a new form x number of times (x = the calculated number of days). Any direction on how to do this would be great! Thanks in advance!
Your form is most likely going to post to save data in rows of your database that represent an instance of a model. So you can use a model method (or, since some would argue that models should only contain persistence logic, a model decorator) to achieve this. For now, it's easiest to keep it in the model.
Say your model name is Event.
Then you can have start_date and end_date fields on it. These will likely be datetime fields.
Then, you can have a method in your model called, say, days_spread:
def days_spread
end_date.to_date - start_date.to_date
end
Calling to_date on those datetimes will make the result of that subtraction a number of days. You may also need to call to_i on that return value to get an integer.
Then you can just call days_spread.times do { |x| }
It's hard to give you a more specific answer without your data model, but that should get you started.
