What did i want to accomplish:
I had a rails form where i wanted one of the required fields to auto fill with some values.
<% if @issue.safe_attribute? 'subject' %>
<p> <%= f.text_field :subject, value: @issue.project.name, :size => 80, :maxlength => 255, :required => true %></p>
<% end %>
The goal being, a user editing the form should not be able to edit this specific field.
If you're like me, your first thought would be to add disabled: true to the code. This disabled the field but it was triggering validation errors saying the field can't be blank.
After reading about the disabled option, i realized disabled elements are not submitted with the form(thus triggering validation) while readonly as its name says it, cannot be modified by a user interaction.
More info here
How did i accomplish it:
Replace disabled: true with readonly: true
Result:
<% if @issue.safe_attribute? 'subject' %>
<p> <%= f.text_field :subject, value: @issue.project.name, readonly: true, :size => 80, :maxlength => 255, :required => true %></p>
<% end %>
Moral of the story: Should've taken HTML course seriously😉
