NoMethodError in BlogsController#create

I've spent the last three hours trying to find a solution to this and checked everything I could find here on StackOverflow but no go.

I am specifically getting this error: "undefined method[]' for nil:NilClass"`

And the application trace gives me this: app/controllers/blogs_controller.rb:7:increate'`

I think it has something to do with how I am passing the params but I can't figure out what's wrong. Here's my Controller code:

class BlogsController < ApplicationController
def index
  @blogs = Blog.all
end

def new
  @blog_entry = Blog.new
end

def create
  Blog.create(title: params[:blogs][:title], content: params[:blogs][:content])
  redirect_to action: 'index'
end
end

Here's my new.html.erb file:

<%= form_for @blog_entry, as: :post, url: {action: "create"} do |f| %>
  Title: </br>
  <%= f.text_field :title %> <br />
  Content: <br />
  <%= f.text_area :content %> <br />
  <%= f.submit "Publish", class: "btn btn-primary" %> <br />
<% end %>

Here's the relevant log file:

Hopefully someone has an idea. Please?

this should do it:

def create
  Blog.create(params[:blog])
  redirect_to action: 'index'
end

let me know if it's not. I'll try to revise my answer, and paste please the full error trace here in case it's not working. The console logs too, as you initialize @blog_entry in the new action you might need to create blog with Blog.create(params[:blog_entry])

EDIT

from console "post"=>{"title"=>"first entry 5", "content"=>"new entry"}

means you need to create a blog entry with: Blog.create(params[:post])
