How to read information from request data to controller

i'm trying to add the model Posts to Blog. Post has blog_id. I need to set it when post create.

= link_to 'New Post', new_post_path(blog_id: @blog.id)

Here is the button to create new post. In address i see:

http://localhost:3000/posts/new?blog_id=27

But I dont know how to send this blog_id to post_form. Should I use hidden form or what? Or maybe i need to write something in controller. Bear to me, i'm new at rails. Also, i want to know, is it the right way to set blog_id to post?

upd _post_form

= simple_form_for [@post] do |f|
  = f.error_notification

  .form-inputs
    = f.input :title
    = f.input :content

  .form-actions
    = f.button :submit

Just add a hidden_field and access params[:blog_id] which you are sending with new_post_path

= simple_form_for [@post] do |f|
  = f.error_notification

  .form-inputs
    = f.input :title
    = f.input :content
    = f.hidden_field :blog_id, value: params[:blog_id]

  .form-actions
    = f.button :submit

You should use relations between posts and blog, declare it in the posts model as has_many or has_one relationship so that will give you the chance to access to the object as:

@blog = blog.posts.find(:id)

i suggest you to follow this part of the tutorial: https://www.railstutorial.org/book/user_microposts it really helped my while doing a project
