Answer 1

You can specify custom label text via i18n. In config/locales/en.yml, and assuming your user model is named user, you can add the following:

helpers:
    label:
      user:
        name: Your Name

This will allow you to keep using

<%= f.label :name %>

without having to hardcode Your Name.

For more information about i18n, see this. Documentation on the label refer to this.

Answer 2

i18n with rails 5.2.2 this works perfectly.

Translate labels, placeholders, and buttons on devise forms or other forms.

<%= form_for(resource, as: resource_name, url: session_path(resource_name)) do |f| %>
   <div class="mt-3">
     <label class="float-left"> <%= f.label t(:email) %> </label>
       <%= f.email_field :email, class: 'form-control', placeholder: t('.emailholder') %>
   </div>
   <div class="mt-3">
     <label class="float-left"> <%= f.label t(:password) %> </label>
       <%= f.password_field :password, class: 'form-control', placeholder: t('.passholder') %>
   </div>

   <div class="button">
     <%= f.button t('.signinbtn'), class: "" %>
   </div>
<% end %>

locals file: config/locales/en.yml

en:
  activerecord:
    ....others

  #Found in Views/devise/seasions/new <form> <*label*>
  email: "Email"
  password: "Password"

  #Views/devise <form> <placeholder & buttom>
  devise: #if your using devise forms
    #seasions/new.html.erb
    new:
      emailholder: "enter email here"
      passholder: "enter password"
      signinbtn: "SignIn"

  ....others

Answer 3

The second parameter to label helper will allow you to set custom text.

<%= f.label :name, 'Your Name' %>

Use Ruby on Rails Documentation to look up helper methods.
