Update multiple values with button_to - Rails 4

I'm having trouble updating columns in my table with a button in Rails. I've looked around stackoverflow for answers, but can't seem to get anything working...

In my app, I want users to be able to "rent" and "return" pins. When they click the "Rent" button, I want it to change the pin's columns.

Example: rented: => true, renter_id: 1"

In my Pins controller:

def rent
@pin = Pin.update_attribute(:renter_id => @user.id)
end

In my View:

<%= button_to "Rent Now!", {:controller => "pins", :action => "rent", :renter_id => @user.id }, :class => 'btn btn-success btn-lg btn-block'%>

Schema:

create_table "pins", force: true do |t|
t.string   "description"
t.string   "link"
t.boolean  "rented"
t.integer  "renter_id"
end

One problem is that update_attribute is an instance method. But you are trying to call it as a class method on Pin. Perhaps do a controller like so.

def rent
  @pin = Pin.find(params[:id])
  if @pin.update_attributes(renter_id: @user.id)
    #handle success
  else
    #handle failure
  end
end

Also make sure that your routes are properly set up as a post request.

update_attribute takes 2 arguments, the attribute and the value

So it should be like this

update_attribute(:renter_id, @user.id)

If you want to update multiple attributes at once or if you want validations to be triggered, use update_attributes

update_attributes(:attr1 => value1, :attr2 => value2)
