Custom text for rails form_for label

问题

I want to display a label in form_for:

<div class="field">
  <%= f.label :name %><br />
  <%= f.text_field :name %>
</div>

This generates the label "Name", but I want it to be "Your Name". How can I change it?

回答1:

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.

回答2:

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.

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
