Routing form submits to home page view

Question

I have a form to collect names and emails to be stored for my mailing list and am having an issue with my routes.

I am using rails 4 with simple form and when the user hits submit they are automatically redirected to the "list" of all the details entered this is standard, I would like them to be routed to the home page instead?

I have basically generated a scaffold for this 'temporary' data collection, I am also wondering if there is a gem to handle this better?

I have been going round in circles for a while now any help would be greatly appreciated.

class DetailsController < ApplicationController
before_action :set_detail, only: [:show, :edit, :update, :destroy]

def index
 @details = Detail.all
end

def show
end

def new
 @detail = Detail.new
end

def edit
end

def create
 @detail = Detail.new(detail_params)

respond_to do |format|
  if @detail.save
    format.html { redirect_to @detail, notice: 'Detail was successfully created.' }
    format.json { render :show, status: :created, location: @detail }
  else
    format.html { render :new }
    format.json { render json: @detail.errors, status: :unprocessable_entity }
  end
 end
end

def update
respond_to do |format|
  if @detail.update(detail_params)
    format.html { redirect_to @detail, notice: 'Detail was successfully updated.' }
    format.json { render :show, status: :ok, location: @detail }
  else
    format.html { render :edit }
    format.json { render json: @detail.errors, status: :unprocessable_entity }
  end
end
end

def destroy
@detail.destroy
respond_to do |format|
  format.html { redirect_to details_url }
  format.json { head :no_content }
end
end

private
def set_detail
  @detail = Detail.find(params[:id])
end

def detail_params
  params.require(:detail).permit(:first_name, :last_name, :email)
end
end

def create
  @detail = Detail.new(detail_params)

 respond_to do |format|
   if @detail.save
     format.html { redirect_to root_path, notice: 'Detail was successfully created.' } #this is where the redirection is happening. change @detail to root_path
     format.json { render :show, status: :created, location: @detail }
  else
    format.html { render :new }
    format.json { render json: @detail.errors, status: :unprocessable_entity }
  end
 end
end

You want to change the redirect statement at the end of the action in the controller which your form is posting to.

For example, if you've got a form such as:

<%= form_for current_user do |f| %>
  <%= f.text_field :name %>
  <%= f.submit 'Save Changes' %>
<%= end %>

You want to keep the changes to current_user happening in the UsersController. You just want the response to the form submission, to land the user on your root_path as defined in your routes. You accomplish this by adding a redirect_to in your UsersController action.

class UsersController < ApplicationController
  def update
    user = User.find(params[:id])
    # ...
    redirect_to root_path
  end
end
