I am having trouble with the form in rails - ruby-on-rails

Question

How can i store image Tags in Tag model. I have albums controller in which i have images on show page .. and in those particular images i want to save tags when i enter.
My albums controller :
class AlbumsController < ApplicationController
before_action :authenticate_user!
def index
#albums = current_user.albums.all
end
def show
#album= current_user.albums.find(params[:id])
end
def new
#album = current_user.albums.new
end
def create
#album = current_user.albums.new(album_params)
if #album.save
redirect_to albums_path
else
render :new
end
end
def edit
#album =current_user.albums.find(params[:id])
end
def update
#album = current_user.albums.find(params[:id])
if #album.update(album_params)
redirect_to albums_path
else
render :edit
end
end
def destroy
#album = current_user.albums.find(params[:id])
#album.destroy
redirect_to albums_path
end
def delete_image_attachment
#image = ActiveStorage::Attachment.find(params[:id])
#image.purge
redirect_to albums_path
end
private
def album_params
params.require(:album).permit(:title, :desciption, images: [])
end
end
My routes.rb file :
Rails.application.routes.draw do
devise_for :users
root to: "albums#index"
resources :albums do
member do
delete :delete_image_attachment
end
resources :comments
resources :tags
end
end

My Tags Controller:
class TagsController < ApplicationController
def create
#image = ActiveStorage::Blob.find(params[:image_id])
tags = params[:tag_name]
tags.each do |tag|
image = params[:image_id]
#tag = Tag.create(tag_name:tag,image_id:image)
redirect_to album_path(#album)
end
end
end
My Tag model:
class Tag < ApplicationRecord
belongs_to :image
end
and this is my show page(well half of it) in which error is coming:
<%= form_for(#tag, url: album_tags_path(#album) ) do |form|%>
<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Enter Tags for your Image here</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<div class="tag-container d-flex flex-wrap">
<input class="form-control py-4 px-3" />
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<%= form.submit class:"btn btn-info"%>
</div>
</div>
</div>
</div>
<% end %>
what is wrong in form_for url here???
I am getting error
ArgumentError in Albums#show

Answer 1

How about letting Rails deduce the route
<%= form_for([#album , #tag]) do |form| %>
