Ruby on Rails: hidden field value not inserting into database

Question

I have two hidden_fields, user_id and skill_id

<%= form_for @skill do |s| %>
  <%= s.label :image, "Upload your skill" %>
  <%= s.hidden_field :user_id, value: current_user.id %>
  <%= s.hidden_field :skill_id, value: params[:id] %>
  <%= s.file_field :image, multiple: true %>
<% end %>

In my controller I have this:

def reviews
  @skill = Skill.new
end

I'm able to get the value for skill_id into my database, but I'm not able to get the value from user_id. In my rails console, I see that user_id is being passed through "skill", but doesn't show in my database.

Parameters: {"utf8"=>"✓", "authenticity_token"=>"5+wxS929uxtt..", "skill"=>{"user_id"=>"7", "skill_id"=>"132", ...

I even checked to see if I'm getting any value with <%= current_user.id %>, which I am.

Maybe someone can guide me to the right path in debugging this issue.

Thanks

Does your HTML shows the user ID correctly? Is the form field named correctly on the generated HTML? — fotanus

Its showing as "user_id"=>"" in your params that is why it is not getting passed to database. — Kirti Thorat

Is your user_id set in the attr_accessible? Also I am assuming that a skill belongs to a user. Why not just use @skill=current_user.skills.new in your controller? — AbM

<%= form_for @skill do |s| %>
   <%= s.label :image, "Upload your skill" %>
   <%= s.hidden_field :user_id, value: current_user.id %>
   <%= s.hidden_field :skill_id, value: params[:id] %>
   <%= s.file_field :image, multiple: true %>
<% end %>

This will go to the create action

So what you really want is to update an existing one since you are passing an existing skills id

def reviews
  @skill = Skill.find params[:id]
end

Now your form can use this

<%= form_for @skill do |s| %>
   <%= s.label :image, "Upload your skill" %>
   <%= s.hidden_field :user_id, value: current_user.id %>
   <%= s.file_field :image, multiple: true %>
<% end %>

It is now go to the update action, in your controller.

def update
  @skill = Skill.find params[:id]
  @skill.update_attributes params[:skill]
  redirect_to root_path # redirect to somewhere
end

Try this.

I don't think you're understand my questions

sonnyhe2002 Over a year ago

Your problem is that you cannot get user_id into the database. You can get the user_id from the way above and then save it to your @skill. and do you have any line like this Skill.create params[:skill]

no, I have only .new. If I do .create, then my other fields don't get inputed unless I put it into create(params...)

Ok I updated my answer to have some kind of save in the database

You need a create controller that would look something like this:

def create
  @skill = Skill.new(params[:skill])
  if @skill.save
    # Handle a successful save.
  else
    render 'new'
  end
end

You may want to change the name of the def reviews controller to def new, and also add the new routes to config/routes.rb
