has_many :through association issue in rails5

user has_many project and project has many user.

project_user table has attribute project_id and user_id.

using devise gem for users.

when ever a user creates new project, project gets created by users. but project is not seen by user in index.html.erb view.

here is my code: project.rb

  has_many :project_users
  has_many :users, through: :project_users

project_user.rb

class ProjectUser < ApplicationRecord
  belongs_to :user
  belongs_to :project
end

user.rb

  has_many :project_users
  has_many :projects, through: :project_users

projects_controller.rb

  def index
    @projects = current_user.projects.all.order("created_at DESC")
  end

  def create
    @project = current_user.projects.build(project_params)

    respond_to do |format|
      if @project.save

        format.html { redirect_to projects_url, notice: 'Project was successfully created.' }
        format.json { render :show, status: :created, location: @project }
      else
        format.html { render :new }
        format.json { render json: @project.errors, status: :unprocessable_entity }
      end
    end
  end
      params.require(:project).permit(:project_name, :from_date, :to_date)

index.html.erb#project

<% @projects.each do |project| %>
<% end %>

form.html.erb(project)

<%= form_with(model: project, :html => {:id => 'project-form-validation'}, local: true) do |form| %>

<div class="row select-date-wrapper">
  <div class="field columns large-6">
    <%= form.label :project_name,:class=>"required" %>
    <%= form.text_field :project_name %>
  </div>

  <div class="field columns large-2">
    <%= form.label :from_date,:class=>"required" %>
    <%= form.text_field :from_date, class: 'datepicker', readonly: 'true' %>
  </div>

  <div class="field columns large-1"></div>

  <div class="field columns large-2">
    <%= form.label :to_date,:class=>"required" %>
    <%= form.text_field :to_date, class: 'datepicker', readonly: 'true' %>
  </div>

  <div class="field columns large-1"></div>
</div>

<div class="row">
  <div class="actions columns button-right">
    <br>
    <%= form.submit :class => "button primary" %>
  </div>
</div>
<% end %>

You need to append the created project to the projects of the user. I think you can do the following:

if @project.save
  current_user.project_users.create(project: @project)
  # rest of the code
end
