My question is how does it work " form_for(resource, : as=>resource_name, ..."
resource is simple a record (or object) - with respect to Devise, it's usually something called User or similar. The rest of the parameters for form_for are options, detailed in the form_for docs.
I notice that both the :email and :username are calling for the email_field, which is a mistake.

I have a devise users table with a fully functioning sign in/up form.
What I was wondering was how to have that users form appear on a different table.
For example
users/sign_in works perfectly
but
I want to have that form appear on movies/index
Ive tried adding the form code to the movies/index but i get this error
undefined local variable or method `resource' for #<#<Class:0x00000102cbf0b8>:0x00000103bb6d78>
This is the sign in form
<%= form_for(resource, :as => resource_name, :url => session_path(resource_name)) do |f| %>
<div><%= f.label :email %>
<%= f.email_field :email, :autofocus => true %></div>
<div><%= f.label :password %>
<%= f.password_field :password %></div>
<% if devise_mapping.rememberable? -%>
<div><%= f.check_box :remember_me %> <%= f.label :remember_me %></div>
<% end -%>
<div><%= f.submit "Sign in" %></div>
<% end %>
<%= render "devise/shared/links" %>
Thanks!
You can generate the views (I understand you already did that) and you can override the controllers, or, in your case, you can watch the controllers of Devise, take the code that you need, and in your view call a partial (from the Devise views).
I did something like that a few months ago, but what I did (that I don't fully suggest but I haven't find a better way) was to take the code from the Devise views, and copy the code in another view with some modifications:
<%= form_for(User.new, :as => "user", :url => session_path("user"), :remote => true) do |f| %>
<div><%= f.label :email %><br />
<%= f.email_field :email %></div>
<div><%= f.label :password %><br />
<%= f.password_field :password %></div>
<div><%= f.check_box :remember_me %> <%= f.label :remember_me %></div>
<div><%= f.submit "Sign in" , :class=>"blue_submit_degradiant", :id =>"sign_in_user"%></div>
<% end %>
It works, but the right way is to have a #user instead of User.new
The form path is user/invitations/invitations/edit.html.erb and new.html.erb
Edit.html.erb
<h2><%= t 'devise.invitations.edit.header' %></h2>
<%= form_for resource, :as => resource_name, :url => invitation_path(resource_name), :html => { :method => :put } do |f| %>
<%= devise_error_messages! %>
<%= f.hidden_field :invitation_token %>
<p><%= f.label :username %><br />
<%= f.text_field :username %></p>
<p><%= f.label :password %><br />
<%= f.password_field :password %></p>
<p><%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation %></p>
<p><%= f.submit t("devise.invitations.edit.submit_button") %></p>
<% end %>
I added the following by myself in the edit.html.erb but the form isn't showing up the fields
<p><%= f.label :username %><br />
<%= f.text_field :username %></p>
Please let me know how to deal with this. And customize forms for devise_invitable
I Generated views again by following command:
rails generate devise_invitable:views users
and then found that the nesting done users/invitations/invitaions/edit.html.erb was wrong.
It should be like views/users/invitations/edit.html.erb
This solved my problem and now i am able to customize devise_invitable form.
Your replacement form should go here
app/views/devise/invitations/edit.html.erb
When users register, I want them to be able to upload an avatar. The new registration .html.erb looks like this:
<h2>Sign up</h2>
<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => {:multipart => true} ) do |f| %>
<%= devise_error_messages! %>
<div>
<%= f.label :username %><br />
<%= f.text_field :name %>
</div>
<div>
<%= f.label :image %><br />
<%= f.file_field :image %>
</div>
<div><%= f.label :email %><br />
<%= f.email_field :email %></div>
<div><%= f.label :password %><br />
<%= f.password_field :password %></div>
<div><%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation %></div>
<div><%= f.submit "Sign up" %></div>
<% end %>
<%= render "links" %>
User.rb:
class User < ActiveRecord::Base
....
mount_uploader :image, ImageUploader
ImageUploader exists...
When I try to visit the view, it tells me that User::ImageUploader doesn't exist. When I try to specify the fully qualified name of the class in the user model, either as an 'include' statement or as an argument to the mount_uploader function, it can't find that either. Do I need to somehow build in a separate form_tag in that view? I'm sure this has been done before. Any help is appreciated.
Have you:
Added an :image column to your User model?
Defined the uploader app/uploaders/image_uploader.rb?
Restarted your server?
You shouldn't need to have this as a separate form tag, as long as the image attribute exists on the User model.
You may need to check your form markup. I notice you have :username on the label and :name on the field.
Try changing:
<%= f.label :username %><br />
<%= f.text_field :name %>
to
<%= f.label :name, "username" %><br />
<%= f.text_field :name %>
I am trying to add forms fields to my Devise user registration view. This has been achieved and the validation runs when I submit the form. However, if I get any form errors, the input data does not re-populate the form field as per the original form although I can see the correct values in my little debugger I've added to the development views.
Here is my view:
<h2>Sign up</h2>
<% resource.build_profile %>
<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
<%= devise_error_messages! %>
<div><%= f.label :email %><br />
<%= f.email_field :email %></div>
<div><%= f.label :username %> <i>(this cannot be changed so choose wisely)</i><br />
<%= f.text_field :username %></div>
<div><%= f.label :password %><br />
<%= f.password_field :password %></div>
<div><%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation %></div>
<%= f.fields_for :profile do |profile_form| %>
<div><%= profile_form.label :full_name %><br />
<%= profile_form.text_field :full_name %></div>
<div><%= profile_form.label :birth_date %><br />
<%= profile_form.date_select :birth_date, start_year: Time.now.year, end_year: Time.now.year - 80, order: [:day, :month, :year], prompt: { day: 'Choose day', month: 'Choose month', year: 'Choose year' } %></div>
<div><%= profile_form.label :gender %><br />
<%= profile_form.select :gender, { "Male" => '0', "Female" => '1' } %></div>
<div><%= profile_form.label :postcode %><br />
<%= profile_form.text_field :postcode %></div>
<div><%= profile_form.label :description, "About you" %><br />
<%= profile_form.text_area :description %></div>
<% end %>
<div><%= f.submit "Sign up" %></div>
<% end %>
<%= render :partial => "devise/shared/links" %>
I don't have a controller code to show because it uses the Devise code inside the Gem. What am I doing wrong / not doing?
You are rebuilding the profile every time with build_profile, it means that when the form in going to be redisplayed, it's using a new instance of profile, not the one with errors. Just change that code so it only builds the profile if one does not exist:
resource.build_profile unless resource.profile
Something like that should work.
Carlos' answer helped me solve this exact issue.
resource.build_profile unless resource.profile
If your user model has a reference to the profile model, try passing
<%= f.fields_for resource.profile do |profile_form| %>
Right now, you're passing a reference to a model, but the form wants an instance.
When I go to the edit_user_registration_path provided by Devise I have fields such as email and username pre-filled.
I want to create custom user profile page with the similar form for edit user information containing additional fields of dependent model. And I want fields be pre-filled.
How should I do it properly?
The default form provided by Devise:
<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => { :method => :put }) do |f| %>
<%= devise_error_messages! %>
<div><%= f.label :email %><br />
<%= f.email_field :email %></div>
<div><%= f.label :username %><br />
<%= f.text_field :username %></div>
<div><%= f.label :password %> <i>(leave blank if you don't want to change it)</i><br />
<%= f.password_field :password, :autocomplete => "off" %></div>
<div><%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation %></div>
<div><%= f.label :current_password %> <i>(we need your current password to confirm your changes)</i><br />
<%= f.password_field :current_password %></div>
<div><%= f.submit "Update" %></div>
<% end %>
Use nested attributes
In your devise user model, if you have other dependent models, you can add a relationship between those models, like has_many and belongs_to. The do this:
Devise user model:
accepts_nested_attributes_for :name_of_other_model
Then in your form you can use fields_for. fields_for docs
Here's also a great railscast of this here
