Rails nomethod error - ruby-on-rails

Question

I'm new to Rails and am trying to create an application that takes a user request. However this is what is happening when I am trying to create a new request.
Request Controller:
class RequestsController < ApplicationController
before_action :set_request, only: [:show, :edit, :update, :destroy]
# GET /requests
# GET /requests.json
def index
#requests = Request.all
end
# GET /requests/1
# GET /requests/1.json
def show
end
# GET /requests/new
def new
#request = Request.new
end
# GET /requests/1/edit
def edit
end
# POST /requests
# POST /requests.json
def create
#request = Request.new(request_params)
respond_to do |format|
if #request.save # <-------------- The problem is here
format.html { redirect_to #request, notice: 'Request was successfully created.' }
format.json { render :show, status: :created, location: #request }
else
format.html { render :new }
format.json { render json: #request.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /requests/1
# PATCH/PUT /requests/1.json
def update
respond_to do |format|
if #request.update(request_params)
format.html { redirect_to #request, notice: 'Request was successfully updated.' }
format.json { render :show, status: :ok, location: #request }
else
format.html { render :edit }
format.json { render json: #request.errors, status: :unprocessable_entity }
end
end
end
# DELETE /requests/1
# DELETE /requests/1.json
def destroy
#request.destroy
respond_to do |format|
format.html { redirect_to requests_url, notice: 'Request was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_request
#request = Request.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def request_params
params.require(:request).permit(:user_id, :description, :created)
end
end
The error says there is no "Create" method in the requests controller, however the method that is saying this is the create method. I think that a problem is that my view isn't passing the description as a parameter and I'm not sure how to do that/why it's not already.
_form.html.erb (Rendered by edit.html.erb):
%= form_for(#request) do |f| %>
<% if #request.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#request.errors.count, "error") %> prohibited this request from being saved:</h2>
<ul>
<% #request.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<center>
<div class="field">
<%= f.label 'Describe your favor' %><br>
<%= f.text_area :description %>
</div>
<div class="actions">
<%= f.submit %>
</div>
</center>
<% end %>
If someone could show me how to pass the description object as a parameter to my create method and get the method to not crash.
Here is the error log:
NoMethodError (undefined method `Request' for #<Request:0x007f9fbd8992e8>):

Using Request (or Response) as the name of a model is not a very good idea since you will end up shadowing the request object. Which is a core part of Rails controllers.
It will also make it very confusing to reason about your code since it will collide with a core concept in MVC and web development in general.
Use a thesaurus and find another name for your model.
