Question

I’m trying to get a link on an articles show page so that when a user clicks write new review it takes them to the link

where they will be directed to the new reviews page

how can i accomplish this with

Answer 1

In your routes file you would specify a route like this

match '/comic_reviews/:comic_name/reviews/new' => 'reviews#new', via: :get

Then in your reviews controller you would need something like this

reviews_controller.rb

class ReviewsController < ApplicationController

  def new
    @comic = Commic.find_by_name(params[:comic_name])
    if @comic
      @review = @comic.reviews.build
      render 'new'
    else
      #Render some error page since comic was not found
    end
  end
end

You will then have access to @comic and @review in your reviews/new view so you could build a form that just makes a post to create a review and allows you to store it. This should get you going.

Edit

In your new view you’d need to have a form that looks something like this

<%= form_for @review do |f| %>
  <%= f.label :some_attribute %>:
  <%= f.text_field :some_attribute %><br />

  <%= f.submit %>
<% end %>

This will be expecting you have a route to create a review in your routes file and an action in your ReviewsController.

If you are struggling with such topics I suggest you read over this excellent tutorial

Or just read through the documentation for Rails API which will give you pretty accurate examples.
