Creating form_for for atributes User image and description - ruby-on-rails

Question

I have a rails application with devise, and I added to users a profile image, and a description. What I want to do is to create a page (DIFFERENT of the default registration/edit) where the users, after logged in, can set only this two atributes(image and description).
<%= form_for(:user, html: { method: :put, :multipart => true })) do |f| %>
<div class="form-group">
<%= f.label :Profile_Image %>
<%= f.file_field :image, class: "form-control" %>
</div>
<div class="form-group">
<%= f.label :Descrição %>
<%= f.text_area :description, class: "form-control", rows: "10" %>
</div>
<% end %>
I have already tried two different controllers and none of them worked:
def edit
end
def edit
#user = User.find(params[:id])
end
My config -> routes are:
get "edit" => "pages#edit"
post "edit" => "pages#edit"
But when i click submit it does nothing! I am new at rails and I am trying to figure this out for hours... How can I create a page to update only the image and the description? Thanks

Answer 1

You need an update method in your controller. Your edit method allows the form to render, but you need something like this:
def update
current_user.update(user_params)
end
Then you would have another method in your controller called user_params, which would look something like this. I was taught to put it under a private heading.
private
def user_params
params.require(:user).permit(:profile_image, :description)
end
I believe there is a shortcut way of including your params with your update method, but this will do.

Use registration controller devise and you should customize it.
You should have one method with the same name in one controller, you have two edit method. Change one edit method to update method ( reference : Allow users to edit their account )
pages_controller.rb
class PagesController < Devise::RegistrationsController
def edit
#user = current_user
end
def update
#user = current_user
successfully_updated = if needs_password?(#user, params)
#user.update_with_password(devise_parameter_sanitizer.for(:account_update))
else
params[:user].delete(:current_password)
#user.update_with_password(devise_parameter_sanitizer.for(:account_update))
end
if successfully_updated
set_flash_message :notice, :updated
# Sign in the user bypassing validation in case his password changed
sign_in #user, :bypass => true
redirect_to after_update_path_for(#user)
else
render "edit"
end
end
private
def needs_password?(user, params)
user.email != params[:user][:email] || params[:user][:password].present?
end
end
application_controller.rb
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
before_filter :configure_permitted_parameters, if: :devise_controller?
def configure_permitted_parameters
devise_parameter_sanitizer.for(:account_update) do |u|
u.permit(:description, :image, :email, :password, :password_confirmation)
end
end
end
You have wrong http verb (post), you need PUT/PATCH not POST
devise_scope :user do
get "edit" => "pages#edit"
put "update" => "pages#update"
end
On your view looks like (example and not tested)
<%= form_for(#user, :url => update_pages_path, :html => { :method => :put }) do |f| %>
<%= devise_error_messages! %>
<div class="form-group">
<%= f.label :image, "Profile Image" %>
<%= f.file_field :image, class: "form-control" %>
</div>
<div class="form-group">
<%= f.label description, "Descrição" %>
<%= f.text_area :description, class: "form-control", rows: "10" %>
</div>
<% end %>
<%= f.submit "Save Image" %>
