Rails update_Attributes(params[:user]) - ruby-on-rails

Question

I have a User show function that makes an api call and updates the user attributes, but I'm having trouble saving the changes.
def show
#user = User.find(params[:id])
... change attributes of #user ...
if #user.update_attributes(params[:user])
p "Saved"
else
p "Failed"
end
end
I'm updated two attributes (:today_steps and :year). Both are accessible in the user.rb. The challenge is that :year is a Serialized Array, but I'm not sure how that changes anything
this setup has returned a 'Failed' every time. i have also tried 'params[:id]' but I receive the error
undefined method `stringify_keys' for "1":String
Any ideas on how to solve this? thanks

def show
#user = User.find(params[:id])
if (#user.device != nil)
#device = #user.device
client = Fitgem::Client.new(
#api client - haven't figured out my security yet, so I won't post it
)
now = Time.now()
last = #device.lastUpdated
while now.to_date > last.to_date
day = client.activities_on_date last.strftime("%Y-%m-%d")
break if day['errors'] != nil
day = day['summary']['steps']
last = last + 1.days
#user.year = #user.year.unshift(day)
end
day = (client.activities_on_date 'today')
if day['errors'] == nil
#user.today_steps = day['summary']['steps']
if now.day != last.day
#user.year.unshift(#user.today_steps)
else
#user.year[0] = #user.today_steps
end
end
#device.lastUpdated = now
p #user.year
#user.device.save
if #user.update_attributes(params[:user])
p "Updated"
else
p "Failed to Update"
end
end
#competitions = #user.competitions.paginate(page: params[:page])

Answer 1

Your code is as
#user = User.find(params[:id])
... change attributes of #user ...
if #user.update_attributes(params[:user])
#the log
Started GET "/users/2" for 127.0.0.1 at 2014-02-25 17:15:09 -0800
Processing by UsersController#show as HTML
Parameters: {"id"=>"2"}
the log clearly states that the show method receives only 'id' whereas in your controller your expect a hash 'user' which can be supplied to update_attributes.
'show' expects to get an attributes hash to stringify it's keys for the column names.
