Implementation of user information edit page

First, specify the link destination so that the routed users / registrations # edit will be executed.

Prefix                 Verb   URI Pattern               Controller#Action
edit_user_registration GET    /users/edit(.:format)     users/registrations#edit

As described below.

<%= link_to 'My page', edit_user_registration_path(current_user), class: "user-nickname" %>

Edit devise controller

Since the function to update data without a password is implemented in devise's controller, Generate a devise controller in the terminal.

$ rails g devise:controllers users

Edit the generated RegistrationsController as follows.

`app>controllers>users>registrations_controlle.rb`


class Users::RegistrationsController < Devise::RegistrationsController
  before_action :configure_account_update_params, only: [:update]

  protected
  
  def update_resource(resource, params)
    resource.update_without_password(params)
  end

  def after_update_path_for(_resource)
    root_path
  end

  def configure_account_update_params
    devise_parameter_sanitizer.permit(:account_update, keys: [:nickname])
  end
end

I am updating with update_resource without a password. After_update_path_for specifies the redirect destination after updating. In configure_account_update_params, this time only the column called nickname of the User table is allowed to be updated.

See the official wiki for details. https://github.com/heartcombo/devise/wiki/How-To:-Allow-users-to-edit-their-account-without-providing-a-password

Edit view file of devise edit

Generate a devise view file in the terminal.

$ rails g devise:views

Edit edit.html.view of the generated view file so that it has only the required input form.

`erb:app>views>devise>registrations>edit.html.erb`


<h2>Edit <%= resource_name.to_s.humanize %></h2>

<%= form_for(resource, as: resource_name, url: registration_path(resource_name), html: { method: :put }) do |f| %>
  <%= render "devise/shared/error_messages", resource: resource %>

  <div class="field">
    <%= f.label :nickname %><br />
    <%= f.text_field :nickname, autofocus: true, autocomplete: "nickname" %>
  </div>

  <div class="field">
    <%= f.label :email %><br />
    <%= f.email_field :email, autofocus: true, autocomplete: "email" %>
  </div>

  <% if devise_mapping.confirmable? && resource.pending_reconfirmation? %>
    <div>Currently waiting confirmation for: <%= resource.unconfirmed_email %></div>
  <% end %>

  <div class="actions">
    <%= f.submit "Update" %>
  </div>
<% end %>

Edit routes.rb

Edit as follows and specify the controller at the time of registration.

`routes.rb`


devise_for :users, controllers: {
    registrations: 'users/registrations'
  }

User model password validation edit

When updating, be careful not to be hit by password validation It is added as on :: create. With this description, password validation will be applied only when the create action is executed.

`app>models>user.rb`


  with_options presence: true do
    validates :nickname, :birthday
    validates :email, uniqueness: true
    validates :first_name, :last_name, format: { with: regexp_name }
    validates :first_name_read, :last_name_read, format: { with: regexp_name_read }
    validates :password, format: { with: regexp_password }, on: :create
  end

By implementing the above, it was possible to update the table of devise's User model without a password. Thank you for visiting our website.
