[RUBY] [Caution !!] Precautions when converting Rails devise and view files to haml

Good evening Aloha man, Yasunori!

Today I'm going to talk about the stumbling block I encountered while modifying the devise view file.

However, if you have the premise, please refer to it! !!

Premise

Gem while creating an application in Rails Those who use devise and also convert html.erb to html.haml with haml-rails etc.

Status

I wanted to add a name input field to the view file of the new registration page of devise and modified the code.

`ruby:views/users/registrations/new.html.haml`


%h2 Sign up
= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f|
  = render "users/shared/error_messages", resource: resource
  .field
    = f.label :name
    %br/
    = f.text_field :name, autofocus: true
  .field
    = f.label :email
    %br/
    = f.email_field :email, autofocus: true, autocomplete: "email"
  .field
    = f.label :password
    - if @minimum_password_length
      %em
        (#{@minimum_password_length} characters minimum)
    %br/
    = f.password_field :password, autocomplete: "new-password"
  .field
    = f.label :password_confirmation
    %br/
    = f.password_field :password_confirmation, autocomplete: "new-password"
  .actions
    = f.submit "Sign up"
= render "users/shared/links"

So, add the: name field and it's perfect! !! I thought ... ファイル名

...e? Has nothing changed? ?? that? ?? ??

Did you make a mistake in the view file to be corrected? Even if I check it, it definitely says registrations ...

For some reason, I'm referring to new.html.erb! ?? Moreover, the reference destination is ʻapp / views / deviseregistrations / new.html.erb`! ??

When I looked it up, I could see the cause.

Cause

Due to the configuration of my application, devise had a User model, so when I generated the view file of devise, I typed the command $ rails g devise: views users, but this seems to be the cause. If there is no model of devise other than ʻUser model in the first place, it seems that only $ rails g devise: views` was enough.

It may be more correct to say that there is only ___1 __ in the devise model, rather than other than the User model.

What is the difference between the two commands?

The directory structure of the generated view file will change a little. Specifically, if you type the command $ rails g devise: views users,

Directory and view files will be created under ʻapp / views / users / `.

On the other hand, if you type the command $ rails g devise: views

Directory and view files will be created under ʻapp / views / devise`.

_devise directory _...

This is it! !!

Yes, I was committing when I generated the view file, so after deleting the commit history and retyping the command, I modified the code in the new view file.

Then ...

Alright! !! A name input field has been added! !!

The reference destination is also properly new.html.haml! !!

Conclusion

When generating a view file of devise, __basic __ $ rails g devise: views is OK !!

Please be careful, too! !!
