I have a user model that has fields for first_name, last_name, email, and password. After a user signs up under their user profile page I would like to allow certain fields and not others to show on a form to update part of the user info.

For example I would like just the first_name to be shown as a field when I render a form for them to edit their name. How do I handle this? Should I make a new route and a controller action that lets me update just this one field? or do I just hide all the other fields and submit them in the background without the user seeing them?

<div class="signup_user">

  <div class="container-fluid">

    <div class="col-md-5 col-sm-12 centered">



      <%= form_for(@user) do |form| %>



      <%= render "shared/errors", object: @user %>

      <%= render "shared/flash" %>



        <div class="card card-default">

          <div class="card-body">



            <h1>Create account</h1>  



            <%= form.label :first_name %>

            <%= form.text_field :first_name, size: 40, autofocus: true, class: "required form-control" %>              



            <%= form.label :last_name %>

            <%= form.text_field :last_name, size: 40, class: "required form-control" %>



            <%= form.label :email %>

            <%= form.email_field :email, size: 40, class: "required form-control" %>



            <%= form.label :password %>

            <%= form.password_field :password, size: 40,  placeholder: "At least 10 characters", class: "required form-control" %>



            <%= form.label :password_confirmation, "Confirm Password" %>

            <%= form.password_field :password_confirmation, size: 40, class: "required form-control" %><br>



            <%= form.submit "Submit", class: 'btn btn-block btn-outline-primary' %>



           <% end %>



           <hr>

           <p>Already have an account? <%= link_to "Sign In", new_session_path %></p>



        </div>

      </div>



    </div>

  </div><!--./container-->

</div><!--./signup_user-->

after the initial signup I would like to just show 1 field like this for editing just the user name.

<div class="signup_user">

      <div class="container-fluid">

        <div class="col-md-5 col-sm-12 centered">



          <%= form_for(@user) do |form| %>



          <%= render "shared/errors", object: @user %>

          <%= render "shared/flash" %>



            <div class="card card-default">

              <div class="card-body">





                <%= form.label :first_name %>

                <%= form.text_field :first_name, size: 40, autofocus: true, class: "required form-control" %>              







        </div>

      </div><!--./container-->

    </div><!--./signup_user-->

The easiest way is use the action_name helper and create some conditional logic that will conditionally render the fields that you only want to show on the new action, e.g. action_name == "new"

I'd make two definitions of strong parameters on the controller:

def create_params

  params.require(:user).permit(:first_name, :last_name, :email, :password)

end



def update_params

  params.require(:user).permit(:email, :password)

end

Then in your create/update methods just allow each different definition. You don't need a new view or a new model if you just restrict the params based on the action.

def create

  @user.create(create_params)

  redirect_to users_path

end



def update

  @user.update_attributes(update_params)

  redirect_to users_path

end

Makes sense to me, and that way you don't have to create anything superfluous. Then fields will be rejected in a secure way the way they should be. Then you can adjust the view with action_name == 'edit' or similar.

You can generate an additional view by creating a new model.

Example :

models/user_edit.rb

class User_Edit < User

end

models/user.rb

class User < ApplicationRecord

...

end

routes

  resources :users

  devise_for :users, path: 'users', controllers: {

        sessions:           "users/sessions",

        passwords:          "users/passwords",

        registrations:      "users/registrations",

        confirmations:      "users/confirmations",

      }

  devise_for :users_edit, path: 'users_edit', controllers: {

        registrations:      "users_edit/registrations",

      }

And so you will have :

views/users/registrations/edit.html

and

views/users_edit/registrations/edit.html
