Need help debugging syntax error from Agile Web Development, 3RD Edition

Hi--

I''m having trouble with a syntax error, which I''m working with
on page
89 of Agile Web Development. I''m getting the following syntax error:

/Users/pdenlinger/Sites/depot/app/models/product.rb:4: syntax error,
unexpected tSYMBEG, expecting kDO or ''{'' or
''(''
  validates_numericality_of :price
                             ^
/Users/pdenlinger/Sites/depot/app/models/product.rb:9: syntax error,
unexpected tASSOC, expecting kEND
...                   :message => ''must be a URL for GIF,
JPG'' ...
                              ^

The original code I have on the model (product.rb) is:

class Product < ActiveRecord::Base

  validates_presence_of :title, :description, :image_url,
  validates_numericality_of :price
  validate :price_must_be_at_least_a_cent
  validates_uniqueness_of :title
  validates_format_of :image_url,
                      :with => %r{\.(gif|jpg|png$)}i
                      :message => ''must be a URL for GIF,
JPG'' + ''or
PNG image''

protected
  def price_must_be_at_least_a_cent
    errors.add(:price, ''should be at least 0.01'') if
price.nil? ||
    price < 0.01
  end

end


Thanks for your help.

Paul

Re: Need help debugging syntax error from Agile Web Development, 3RD Edition

That''s an easy one, really. You got a typo.


******************************************
class Product < ActiveRecord::Base

 validates_presence_of :title, :description, :image_url,
 validates_numericality_of :price
******************************************

remove the last comma from the line above the validation of the numericality
of :price

Cheers,
Chris

Re: Need help debugging syntax error from Agile Web Development, 3RD Edition

As far as I can see there is an extra '','' (comma) at the end
of the first
statement, the statement just before your validates_numericality_of. I have
indicated that below within *[]*. Removing that should solve your issue.

class Product < ActiveRecord::Base

 validates_presence_of :title, :description, :image_url*[,]*
 validates_numericality_of :price
 validate :price_must_be_at_least_a_cent
 validates_uniqueness_of :title
 validates_format_of :image_url,
                     :with => %r{\.(gif|jpg|png$)}i
                     :message => ''must be a URL for GIF,
JPG'' + ''or
PNG image''

protected
 def price_must_be_at_least_a_cent
   errors.add(:price, ''should be at least 0.01'') if price.nil?
||
   price < 0.01
 end

end

Thanks & Regards,
Dhruva Sagar.

Re: Need help debugging syntax error from Agile Web Development, 3RD Edition

Thank you.

I''m still getting an error for the second statement:

/Users/pdenlinger/Sites/depot/app/models/product.rb:9: syntax error,
unexpected tASSOC, expecting kEND
...                   :message => ''must be a URL for GIF,
JPG'' ...
                              ^

The code is as follows:

 validates_format_of :image_url,
                      :with => %r{\.(gif|jpg|png$)}i
                      :message => ''must be a URL for GIF,
JPG'' + ''or
PNG image''

Thanks,
Paul

I know it is difficult when just starting, but I would have thought
that following the previous problem with a comma that you could have
worked out this one yourself.  When you see a syntax error the problem
saying something unexpected found that means that there is likely an
error a bit before the point noted.  The basic syntax of
validates_format_of (or any function for that matter) is
validates_format_of <parameter>, <parameter>, ...   :image_url is
the
first parameter, :with => ... is the second and :message => .. is the
third.  I am sure you can see the error, or at least the one
generating the message.

Hi Paul,

This is the same error as the previous one, but in reverse. ;)

Hi Colin--

Thanks. Got the errors.

Two missing commas. Will try to avoid repeating that mistake in the
future.
