Users can't visit other users in my ruby application - ruby-on-rails

Question

I looked around a lot and found only one question like the one I am asking, And the information in it did not help me with my issues. What I am having an issue with is my users, I have several users. You're able to navigate to the page that displays every user, each one is clickable. But when ever I'm signed in to a user say Profile(1) and I wanna visit Profile(2) page it just loads Profile(1)'s credentials. Age, Bio, and Picture. Whats my issues here? It may be a simple fix and if so then thank you for the help in advance!
This is the page that list all users index.html.erb,
<div class="all_users">
<div class="container">
<p id="notice"><%= notice %></p>
<h1>Listing Users</h1>
<table>
<thead>
<tr>
<th colspan="3"></th>
</tr>
</thead>
<tbody>
<% #users.each do |user| %>
<ul class="media-list">
<li class="media">
<div class="media-left">
<%= link_to image_tag user.profile_picture.url(:thumb) %>
</a>
</div>
<div class="media-body">
<h4 class="media-heading">Name: <%= link_to user.first_name, dashboard_path %></h4>
<p>Age: <%= user.age %></p>
<p><%= user.bio %></p>
</div>
</li>
</ul>
<tr>
<td><%= link_to 'Show', user %></td>
<td><%= link_to 'Edit', edit_user_path(user) %></td>
<td><%= link_to 'Destroy', #user, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</tbody>
</table>
<br/>
<%= link_to 'New User', new_user_path %>
<%= link_to 'Login', login_path %>
</div>
</div>
Here is the profile page for the users show.html.erb,
<div class="show">
<div class="col-md-3">
<div class="thumbnail">
<% else %>
<%= image_tag #user.profile_picture.url(:medium) %>

<%- #posts.each do |post| %>
<div class="panel panel-default">

<div id="comments-form">

</div>
<% end %>
</div>
Here is my users_controller.rb,
class UsersController < ApplicationController
before_action :set_user, only: [:show, :edit, :update, :destroy]
after_action :signed_in_after_register, only: :create
def index
#users = User.all
#user = User.find(session[:user_id])
end
def dashboard
#user = User.find(session[:user_id]) unless session[:user_id] == ""
redirect_to login_path, notice: "You're not logged in" unless #user
#posts = #user.posts.order("created_at DESC").limit(3)
#comment = Comment.new
#post = Post.new
end
def newsfeed
#user = User.find(session[:user_id]) unless session[:user_id] == nil
redirect_to login_path, notice: "You're not logged in" unless #user
#posts = #user.posts.order("created_at DESC").limit(3)
end
def nav
#user = User.find(session[:user_id])
end
def posts
#user = User.find(session[:user_id])
#posts = #user.posts
end
def destroy
#user = User.find(session[:user_id]) unless session[:user_id] == ""
redirect_to login_path, notice: "You're not logged in" unless #user
end
def welcome
#user = User.find(session[:user_id]) unless session[:user_id] == ""
redirect_to login_path, notice: "You're not logged in" unless #user
end
def show
#user = User.find(params[:user_id]) unless session[:user_id] == ""
redirect_to login_path, notice: "You're not logged in" unless #user
#posts = #user.posts.order("created_at DESC").limit(3)
#comment = Comment.new
#post = Post.new
end
def new
#post = Post.new(params[:post_id])
#user = User.new
end
def edit
end
def create
#user = User.new(user_params)
respond_to do |format|
if #user.save
format.html { redirect_to dashboard_path, notice: 'User was successfully created!' }
format.json { render :show, status: :created, location: #user }
else
format.html { render :new }
format.json { render json: #user.errors, status: :unprocessable_entity }
end
end
end
def update
respond_to do |format|
if #user.update(user_params)
format.html { redirect_to dashboard_path, notice: 'User was successfully updated.' }
format.json { render :show, status: :ok, location: #user }
else
format.html { render :edit }
format.json { render json: #user.errors, status: :unprocessable_entity }
end
end
end
def destroy
#user.destroy
respond_to do |format|
format.html { redirect_to users_url, notice: 'User was successfully destroyed.' }
format.json { head :no_content }
end
end
private
def set_user
#user = User.find(params[:id])
end
def signed_in_after_register
session[:user_id] = #user.id
end
def user_params
params.require(:user).permit(:first_name, :last_name, :bio, :password, :password_confirmation, :email, :age, :profile_picture, :post, :body)
end
end
and this is my user model user.rb,
class User < ActiveRecord::Base
has_secure_password
validates :first_name, :last_name, :email, presence: true, uniqueness: true
validates_inclusion_of :age, in: 10..100
validates :password, presence: true
has_many :posts
has_attached_file :profile_picture, :styles => { :medium => "300x300>", :thumb => "100x100>" },
:default_url => "app/assets/images/missing.png",
:path => ":rails_root/public/system/:class/:attachment/:id_partition/:style/:filename"
validates_attachment_content_type :profile_picture, :content_type => /\Aimage\/.*\Z/
I tried putting in User.find(params[:user_id]) and I get the following error
ActiveRecord::RecordNotFound in UsersController#show
Couldn't find User with 'id'=
EDIT: Here is my routes file,
Rails.application.routes.draw do
root 'welcome#welcome'
get 'login' => 'sessions#login', :as => :login
get 'dashboard' => 'users#dashboard', :as => :dashboard
post 'logging/user' => 'sessions#create'
get 'logout' => 'sessions#destroy', :as => :logout
get 'about' => 'about'
get 'newsfeed' => 'users#newsfeed'
resources :users, except: :show
get 'profile/:id' => 'users#show', as: :profile
resources :posts do
resources :comments
end
get 'index' => 'posts#index'
get 'register' => 'users#new', :as => :register
end

Answer 1

Which link are you clicking to view a user's profile?
<h4 class="media-heading">Name: <%= link_to user.first_name, dashboard_path %></h4>
or:
<td><%= link_to 'Show', user %></td>
If it's the first one why are you linking to dashboard_path? Seems like that should be linking to user_path(user) right?
Might also help to show us your routes file.
