How to parse a Mash from LinkedIn to create a Ruby object

问题

I used LinkedIn gem by pengwynn to get authentication from LinkedIn. Everything works fine, and I get a Mash in a callback that looks like this:

#<LinkedIn::Mash all=[#<LinkedIn::Mash company=#<LinkedIn::Mash id=1422 industry="Banking"    
 name="Company" size="10,001+ employees" ticker="ABC" type="Public Company"> id=2851554 
 is_current=true start_date=#<LinkedIn::Mash month=12 year=2008> summary="" title="Boss">] total=1>

How can I parse it to something similar to Rails params in order to create a new object from it?

Thank you.

When you receive list of connections of any sort from LinkedIn, you need to get to the list from all. On the object you received from LinkedIn, you have {all, total}. total will give you the number of objects in the array, all will give you all of the objects. So if you wanted to turn the first company into a hash, you would call object.all.first.to_hash. You can iterate through all of them by doing object.all.each {|c| # your block}.

If your own Rails models match the objects being returned from the linkedin gem, you can do:

companies.all.each do |company|
  Company.create(company.to_hash)
end

If they don't map 1:1, you can just choose the fields you want:

companies.all.each do |company|
  c = Company.new
  c.name = company.name
  c.year_founded = company.start_date.year
  c.ticker = company.ticker
  # etc. etc. etc.
  c.save
end

You can just call .to_hash to turn a Mash into a Hash (like params).
