Rails 4. Attribute not saving when creating model - ruby-on-rails

Question

I am stumped as to why this isn't working. I have a review system, and a link to create a new review passing 2 attributes; user_id and gigid. Both id's are being generated as integers but when I save the review, the gigid saves as 'nil' rather than the integer.
View:
<%= link_to 'Click here to rate this user', new_user_review_path(:user_id => request.user.id, :gigid => request.gig.id) %>
Here both ID's are set correctly (according to server output). User_id is the user which is to be reviewed (works correctly) and gigid is a reference for post validation. (works correctly until I try and save)
_form :
<%= simple_form_for([#user, #user.reviews.build]) do |f| %>
<div id="rating-form">
<label>Rating</label>
</div>
<%= f.input :comment %>
<%= f.button :submit %>
<% end %>
Controller:
def new
if user_signed_in?
#review = current_user.reviews.new
else
redirect_to(root_url)
flash[:danger] = "You must log in to rate a user"
end
end
def create
#review = #user.reviews.new review_params
#review.reviewed_id = current_user.id
if #review.save
redirect_to user_path(#user)
else
render 'new'
end
end
private
def review_params
params.require(:review).permit(:rating, :comment, :gigid, :user_id)
end
end
Server output when clicking link:
Started GET "/users/21/reviews/new?gigid=17&locale=en" for 127.0.0.1 at 2016-01-13 18:08:26 +0100

I then add a comment and a rating and click create.

I notice that 'gigid' is being completely ignored here, but EVERYTHING else saves fine.
I don't understand why one attribute saves and the other doesn't, any insight would be greatly appreciated!

Answer 1

Your form doesn't have anything for gigid to send it to create action. You can use hidden field in the form like below
<%= simple_form_for([#user, #user.reviews.build]) do |f| %>
<div id="rating-form">
<label>Rating</label>
</div>
<%= f.input :comment %>
<%= f.input :gigid, :as => :hidden, :input_html => { :value => params[:gigid] }
<%= f.button :submit %>
<% end %>

Answer 2

There is no gigid in review params. Look carefully on your params when you are performing POST: "review"=>{"rating"=>"5", "comment"=>"sdfsdfdd"}. Just review and comment. And after it you are doing:
params.require(:review).permit(:rating, :comment, :gigid, :user_id)
