On an older ruby version? Try Date.strptime [0] or even better if you're
trying to parse natural dates as well - the chronic gem [1]

 In your example form you have three separate fields which you need to
 parse into a valid Date. You cannot expect DM to do this on your behalf nor
 should you. DM resources can parse date strings as properties of course,
 but you need to massage your params to get the date into an acceptable
  format. My point was that this would be a responsibility of your web
 framework or front-end not DM.

 A similar example of this is the DateHelper.date_select in rails which
 does some hocus pocus with param suffixes and Date::civil to get the values
 from the three options into a proper date that AR can understand.

Re: [DataMapper] Creating Dates from a form

[DAZ]

Thanks for the reply Ben, 

I'd suggest: 
> def released_on=date
>   super(Date.parse(date).iso8601)
> end


that certainly looks more elegant, but I get an 'invalid date' argument 
error for that if I try to enter the date in the format "10/09/2012", any 
ideas?

cheers,

DAZ

 I think my question is more to do with DataMapper, because DataMapper 
 requires the format to be a Date or DateTime object. My question is how I 
 change what is effectively a string in the params hash into a date object 
 in a neat way. Even if I used a date picker, I would assume that it sends 
 some sort of string to the server rather than an actual Date object?

 I want to be able to create a new song resource by using

   song = Song.create(params[:song])

 The problem I'm having is with the released_on property, since it
 needs to be a Date object.

 At the moment, I am doing this:

   date = Date.new(params[:year].to_i,**pa**rams[:month].to_i,params[:**

   song = Song.create(params[:song].**merg**e(released_on: date))

 Does anybody know any nicer ways of entering a date into a form and

 manipulate the form parameters first?

Re: [DataMapper] Creating Dates from a form

[DAZ]

Hi Ben,

Thanks for the reply. This is what I thought was the case, but I just 
wondered if there were any nice DM methods that I didn't know about that 
parsed strings in a certain format, ready to insert into the database as a 
Date object.

I've found that the jQuery datepicker gives the date in this format 
10/09/2012, so I have added the following method to the Song class to 
change it into a Date object:

  def released_on=date
dates = date.split('/').map{ |s| s.to_i }
super(Date.new(dates[2],dates[0],dates[1]))
  end

Not sure if that's the best way of doing it, but it certainly works!

thanks for the help and feedback!

DAZ

change what is effectively a string in the params hash into a date object 
in a neat way. Even if I used a date picker, I would assume that it sends

Hope that clarifies my question - is there a neat way of converting dates 
to Date objects or is there just some donkey work that needs doing before 
creating the resource?

Re: [DataMapper] Creating Dates from a form

[Ben Lovell]

I think this question would be better served in whichever list pertains to your 
chosen web framework (Sinatra I suspect?) but the simple answer is to use one 
of the many available date pickers.

[DataMapper] Creating Dates from a form

[DAZ]

I have a Song class that looks like this:

  class Song
include DataMapper::Resource
property :id, Serial
property :title, String
property :lyrics, Text
property :length, Integer
property :released_on, Date
  end

Here's my form for creating it:

  







  

I want to be able to create a new song resource by using

  song = Song.create(params[:song])

The problem I'm having is with the released_on property, since it needs to 
be a Date object.

At the moment, I am doing this:

  date = Date.new(params[:year].to_i,params[:month].to_i,params[:day].to_i)
  song = Song.create(params[:song].merge(released_on: date))

Does anybody know any nicer ways of entering a date into a form and being 
able to simply call Song.create(params[:song]) without having to manipulate 
the form parameters first?

cheers,

DAZ
