Read_only field using rendered form

Hi everyone!

I have a form view with an email text field and some other type of field in a view named _form.html.haml, as follows :

= easy_form_for @form, label_col: 'col-md-2', control_col: 'col-md-10' do |f|

    = f.text_field :name,  required: true
    = f.text_field :email, required: true
    = f.text_area  :description, rows: 5

And an edit.html.haml view that inherits from this form as follows:

... page_title

= render 'form'

I would like to make a Patch on this form in the edit.html.haml view just gray the email field and leave the other fields of the form as they are
