Unpermitted parameter with has_many_and_belongs_to :param, through :param - ruby-on-rails

Question

I am having trouble inputting data into my new model.
I created a new model so I can assign Users to Affiliates.
I have a Users, Affiliates, and UserAffiliates model.
UserAffiliates:
belongs_to :users
belongs_to :affiliates
User:
has_and_belongs_to_many :user_affiliate
has_and_belongs_to_many :affiliate, through: :user_affiliate, optional: true
Affiliate:
has_many :user_affiliates
has_many :users, through: :user_affiliates
How it works, is an affiliate can have many users, but a user will ever only have one affiliate. I then have a commission column within the UserAffiliates table to set the commission based on a user by user basis.
I created this form, and it doesn't seem to be working (which is stemmed from a <% #users.each do |user| %> that goes through each user in a table:
<%= form_for user, remote: true do |f| %>
<% f.fields_for :user_affiliates, remote: true do |f| %>
<%= f.text_field :affiliate_id, class: "form-control" %>
<%= f.submit "Add Affiliate", data: {confirm: "Are you sure?"}, class: "btn btn-light" %>
<% end %>
<% end %>
I get this error:
Parameters: {"utf8"=>"✓", "user"=>{"user_affiliates"=>{"affiliate_id"=>"1"}}, "commit"=>"Add Affiliate", "id"=>"2"}
User Load (0.7ms) SELECT "users".* FROM "users" WHERE "users"."id" = $1 LIMIT $2 [["id", 2], ["LIMIT", 1]]

params.require(:user).permit(:name, :approved, :seller, :buyer, :admin, :stripe_account, :email, :password, :password_confirmation, :role, :affiliate_id, :affiliate_ids [], :user_affiliates, :commission)
end
Is my form wrong?
I want to be able to list users in a table as a user.admin, have a text field, and enter an affiliate_id, and then have the user_id and affiliate_id inputted into the UserAffiliate table. I also want to be able to add commission rates that both the user.admin and Affiliate can change.
How can I do this correctly?
Update:
I fixed my params but still have errors:
params:
def user_params
params.require(:user).permit(:name, :approved, :seller, :buyer, :admin, :stripe_account, :email, :password, :password_confirmation, :role, :affiliate_id, :user_affiliates, :affiliate, :commission, affiliate_ids: [])
end

I tried changing it to user_affiliate (non pluar) and plural in all the controller, model, and form. Is there anything i need to do to my update on the users controller?
User Controller update:
def update
#user = User.find(params[:id])
# #affiliate = current_affiliate
respond_to do |format|
if #user.update(user_params) # <- you'll need to define these somewhere as well
if #user.admin?
format.html { redirect_to '/admin/users', notice: "yahoo" }
format.json { render json: #user }
# elsif #affiliate
# format.html { redirect_to '/a/clients', notice: "yahoo" }
# format.json { render json: #user }
else
format.html { render :edit }
format.json { render json: { errors: #user.errors }, status: :unprocessable_entity }
end
end
