undefined method ''match'' with the Linkedin Gem

I have been building a small app to import a cv from linkedin.
Displaying the information is working out perfect, but saving it to
the database is turning out to be a challenge.

The full source code is at https://github.com/brunoamaral/lwork and
the source code of the import function is as follows:

def importcv

	@user = User.find_by_username(params[:username])
    client = LinkedIn::Client.new(@linkedin_apikey, @linkedin_secret)

	t =
current_user.authentications.find_by_provider(''linked_in'')
	client.authorize_from_access(t.token, t.secret)

	@cv = client.profile(:fields =>
[:headline, :first_name, :last_name, :educations, :positions])

	@user.positions << @cv.positions
	@user.positions.save

  end

When running it, I get the message:
undefined method `match'' for LinkedIn::Position::Resource:Class

The model adds the following to users:
has_many :positions, :class_name => LinkedIn::Position::Resource

What bugs me more is that I don''t even know where to start looking for
an answer to this, so any hints on where to search and what to look
for are welcome.

match is a method of String, so I wonder whether it is getting called
on the above type instead of a string.  The error should show a stack
trace which should show you which line of your code it is failing on.
Post the complete error and trace if you cannot work it out.

Re: undefined method ''match'' with the Linkedin Gem

The error message mentions line 44:
	@user.positions << @cv.positions
	@user.positions.save

the full output is here: http://dl.dropbox.com/u/109441/errormessagerails.html

@cv.positions is an array, so from what you''re telling me it should
not use "match" as a method.

Don''t you get a full error trace, in the server terminal window or
log/development.log?

You realise that, if user.positions is also an array that
@user.positions << @cv.positions
will attempt to add the whole array @cv.positions as a single element
on the end of @user.positions.  Not append the contents of
@cv.positions as multiple new elements.  Are you sure you do not want
@user.positions += @cv.positions

I don''t know what @user.positions is of course so I may be
misinterpreting something.

cv.positions is the information the user has in the experience bit of
their LinkedIn profile.
composed of user_id: integer, company: string, end_month: string,
end_year: string, start_month: string, start_year: string

Using += resulted in the exact same error message, which is strange I
was hoping to at least get more information from rails. Maybe it means
the problem is not the line 44 but something else.

Do you mean each member of the array (or association) positions is one
of those.   I am a bit confused by the line @user.positions.save.  Can
you do save on an array?  Or is positions a single record, in which
case it should be called position, singular.

Is there a Position model then, with cv has_many positions ?
What happens if you do something like
@cv.postions.each do |position|
  @user.positions << position
end

Can you  post the model definitions?  Not all the methods just the
definitions and associations and so on.

Have you used ruby-debug or a similar to technique to break in and
check that all the variables are as you expect.

Re: undefined method ''match'' with the Linkedin Gem

adding ruby-debug froze the import page, but I will keep trying to
check the variables as you said.

about the model, the source code is in the github project
https://github.com/brunoamaral/lwork/blob/master/app/models/user.rb

class User < ActiveRecord::Base

	has_many :authentications
	has_many :positions, :class_name => LinkedIn::Position::Resource

This looks wrong, since :class_name is supposed to be a string and
LinkedIn::Position::Resource isn''t

However, not using it only returns

Position(#2174910600) expected, got
LinkedIn::Position::Resource(#2173297260)

I am thinking about taking a different approach, since I can''t figure
out how to save the information I need in one go the other option is
to try to build an import form.
