[RAILS] The devise error message is not displayed properly.


The devise error message didn't display well, so I figured out why. It's not a solution, but I've learned a little about how devicise works, so I'll leave it as a reminder.


When calling a partial template, I changed the variable name in the template from resource to @ model name.

Error message

<%= render "devise/shared/error_messages", resource: resource %>
<%= render "devise/shared/error_messages", resource: @profile %>

Since devise is a framework that can handle multiple model instances, it seems that resource can handle it well. ](Https://teratail.com/questions/139633) Actually, there seems to be another process, but if I changed this to @ model name, it worked.

Other code


Since user registration and profile registration are in a wizard format, profile is processed by the'users / registration'controller.


Rails.application.routes.draw do
  devise_for :users, controllers: {
    registrations: 'users/registrations'
  devise_scope :user do
    get 'profiles', to: 'users/registrations#new_profile'
    post 'profiles', to: 'users/registrations#create_profile'

Table design

I'm using devise to store user information in the users and profiles tables.


#The users table and profiels table look like this.

  create_table "profiles", options: "ENGINE=InnoDB DEFAULT CHARSET=utf8", force: :cascade do |t|
    t.string "favorite_beer"
    t.text "twitter_link"
    t.text "info"
    t.bigint "user_id", null: false
    t.datetime "created_at", precision: 6, null: false
    t.datetime "updated_at", precision: 6, null: false
    t.index ["user_id"], name: "index_profiles_on_user_id"

  create_table "users", options: "ENGINE=InnoDB DEFAULT CHARSET=utf8", force: :cascade do |t|
    t.string "nickname", null: false
    t.string "email", default: "", null: false
    t.string "encrypted_password", default: "", null: false
    t.string "reset_password_token"
    t.datetime "reset_password_sent_at"
    t.datetime "remember_created_at"
    t.datetime "created_at", precision: 6, null: false
    t.datetime "updated_at", precision: 6, null: false
    t.index ["email"], name: "index_users_on_email", unique: true
    t.index ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true

input form

The view of profile registration looks like this. The error message is called in the partial template here, but it seems that the information in the profiles table could not be passed to it.


<h2>Profile registration</h2>
<%= form_with model: @profile, local: true do |f| %>
  <%= render "devise/shared/error_messages", resource: @profile %>

  <div class="field">
    <%= f.label :avatar %><br />
    <%= f.file_field :avatar %>

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

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

  <div class="field">
    <%= f.label :info %><br />
    <%= f.text_area :info %>

  <div class="actions">
    <%= f.submit "sign up" %>
<% end %>

<%= render "devise/shared/links" %>

Source of error message

The error message of devise called by the partial template is as follows


<% if resource.errors.any? %>
<%#To the resource of this ↑ part@Passed profile%>
  <div id="error_explanation">
      <%= I18n.t("errors.messages.not_saved", #The description around here is devise.ja.Described in yml
                 count: resource.errors.count,
                 resource: resource.class.model_name.human.downcase)
      <% resource.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
<% end %>

A file that translates devise into Japanese

Since devise has already been translated into Japanese, the yml file is also translated into Japanese.


# ~abridgement~     
      profile:profile#I added it because I wanted to translate it into Japanese as well.
# ~abridgement~
      already_confirmed:Is already registered. Please login.
      confirmation_period_expired:Has expired.%{period}You need to confirm by. Please make a new request.
      expired:Has expired. Please make a new request.
      not_found:Was not found.
      not_locked:Is not frozen.
#This is not_It seems that the saved place is called by the partial template
        one:Because an error occurred%{resource}Was not saved.
        other: "%{count}Because an error occurred%{resource}Was not saved."


I would like to continue studying in the future. If this sentence contains a ridiculous misunderstanding, please point it out.
