undefined method `nil' for #<Admin:0x00000011ead6f0> - ruby-on-rails

I'm using rails_admin and I have overrided delete action with adding some line of code:
if request.get? # DELETE
respond_to do |format|
format.html { render #action.template_name }
format.js { render #action.template_name, layout: false }
end
elsif request.delete? # DESTROY
redirect_path = nil
# puts 'CUSTOM DELETE'
# This code to assign current user that will delete following object.
# History tracker can not assign current_user by itself.
if #object.has_attribute?(:updater_id)
#object.updater = _current_user
#object.save
end
#auditing_adapter && #auditing_adapter.delete_object(#object, #abstract_model, _current_user)
if #object.destroy
flash[:success] = t('admin.flash.successful', name: #model_config.label, action: t('admin.actions.delete.done'))
redirect_path = index_path
else
flash[:error] = t('admin.flash.error', name: #model_config.label, action: t('admin.actions.delete.done'))
redirect_path = back_or_index
end
redirect_to redirect_path
end
When the delete action is called it throws:
undefined method `nil' for #<Admin:0x00000011ead6f0>
Yes that is strange. I always get undefined methods for nilClasses but this. This is nil for defined object. This happens on #object.updater - _current_user line
#object is model that will be destroyed. _current_user is logged in Admin model.
Why this error is happening?
The models I use are: Category, SubCategory, Sub2Category and Admin.
Category has_many SubCategory, SubCategory has_many Sub2Category. Admin is updater and _current_user.
This error happened when I try to delete Sub2Category via rails_admin.
Backtrace:
NoMethodError (undefined method `nil' for #<Admin:0x00000013b9b960>):

Destroyed object still there?

The "destroy" method is not working on my site. I created a "delete" link, but when I click it I just get redirected.
Here is the controller with the destroy method:
class PostsController < ApplicationController
def index
#posts = Post.all
end
def show
#post = Post.find(params[:id])
end
def new
#post = Post.new
end
def create
#post = Post.new(post_params)
if #post.save
redirect_to #post
else
render :new, status: :unprocessable_entity
end
end
def edit
#post = Post.find(params[:id])
end
def update
#post = Post.find(params[:id])
if #post.update(post_params)
redirect_to #post
else
render :edit, status: :unprocessable_entity
end
end
def destroy
#post = Post.find(params[:id])
#post.destroy
redirect_to root_path, status: :see_other
end
private
def post_params
params.require(:post).permit(:title, :description, :image, :price)
end
end
Nothing fancy. And here is the link in my posts/show.html.erb view:
<%= link_to 'Delete', root_path,
method: :delete,
data: { confirm: 'Are you sure?' } %>
Doesn't work - I just get redirected to the root path, and the post I tried to delete remains.
I tried removing a post in the rails console, and that did work.

Looks like you have an issue with Turbo or Rails UJS.
These should really work and send a DELETE request via javascript:
# Turbo
link_to "delete", #post, data: { turbo_method: :delete }
# Rails UJS
link_to "delete", #post, method: :delete
If your javascript is broken than data and method attributes are ignored and you're just clicking a link to show #post, which is what's happening in the log.
On the other hand:
data-turbo-method changes the link request type from the default GET.
Ideally, non-GET requests should be triggered with forms, but
data-turbo-method might be useful where a form is not possible.
https://turbo.hotwired.dev/reference/attributes
To trigger a DELETE request with a form you can use button_to, which creates a little form and rails correctly handles routing to destroy action:
button_to "Delete", #post, method: :delete
https://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-button_to

Using index with Presenter causes NoMethodError

I tried to learn about presenter and did the following classes
User model with id, first_name, last_name, email
user_controller with the following methods
def index
#users = User.all
render_user_json #users
end
def show
#user = User.find_by_id(params[:id])
if #user.nil?
render json: { message: 'User can not be found' }, status: 404
return
end
render_user_json #user
end
def render_user_json(user)
render json: ::Presenters::User::UserPresenter.new(user).generate
end
UserPresenter class
module Presenters
module User
class UserPresenter
attr_reader :user
def initialize(user)
#user = user
end
def generate
{
id: #user.id,
first_name: #user.first_name,
last_name: #user.last_name,
email: #user.email
}
end
end
end
end
When I go to localhost:3000/users/id it works well
but when I go to localhost:3000/users I get the following error

It seems like it doesn't passed as single users
Rather than this:
render_user_json #users
Either make another method render_users_json (note the plural users) or just call the render from the index method directly like this:
# inside index method
render json: users.map do |user|
::Presenters::User::UserPresenter.new(user).generate
end

Devise sets current_user to nil after I change this users password and sign them back in

if #user.update(user_params)
# password_reset? check's parameter passed to action that a check box was
# checked (which enables/disables password/confirmation fields. If unchecked,
# fields are disabled and no password parameters are sent to this action.
# #user was set to current_user in a before_action already
# inspecting #user at this point returns the same thing as current_user here
sign_in(:user, #user) if password_reset?
# current_user is still set to #user and is valid
# after redirection current_user becomes nil
format.html {
redirect_to home_path, notice: 'Your profile was successfully updated.'
}
else
format.html { render :edit }
end
end
end
...

# Never trust parameters from the scary internet, only allow the white list through.
def user_params

def password_reset?
#user_params["reset_password"] == "1"
end
end

I've searched around and seen by_pass: true being passed to sign_in but that doesn't help. I've also tried #current_user = #user once I've signed the user in (#current_user is the direct instance variable for the Devise controller btw) and that does not help either.
Any ideas?
Devise ignores signin if the user is already signed in, try:
if #user.saved_change_to_encrypted_password? # for rails 5+, for previous - .encrypted_password_changed?
sign_in #user, force: true
end
You can signin new session if the user is already signed in.
Devise said
# Sign in a user bypassing the warden callbacks and stores the user
# straight in session. This option is useful in cases the user is
# signed in, but we want to refresh the credentials in session.
Please use like below one.
bypass_sign_in(#user)

Why isn't my form saving but working with the API only?

I have my form to save to my Stripe_account table. I recently nested the resources and now the form won't save to my database tables. I have it still working with the Stripe API and working there though.
What in my code is lacking?
User Model:
has_one :stripe_account
Stripe_account Model:
belongs_to :users
Stripe_account controller:
def new
#stripe_account = StripeAccount.new
#user = User.find(params[:user_id])
end
def create
#stripe_account = StripeAccount.new(stripe_account_params)
#user = User.find(params[:user_id])
acct = Stripe::Account.create({
.....
.....
#stripe_account.id = current_user.id
#stripe_account.acct_id = acct.id
respond_to do |format|
# #user = User.find(params[:id])
if #stripe_account.save
# current_user = #user
#user.stripe_account = acct.id
format.html { redirect_to new_bank_account_path, notice: 'Stripe account was successfully created.' }
format.json { render :show, status: :created, location: #stripe_account }
else
format.html { render :new }
format.json { render json: #stripe_account.errors, status: :unprocessable_entity }
end
end
end
View:
<%= form_for ([#user, #stripe_account]) do | f | %>
Routes:
resources :users do
resources :stripe_accounts
end
#added for testing
get 'stripe_' => "stripe_account#create"
get 'stripe_new' => "stripe_account#new"
Here's my routes maybe can help?: https://pastebin.com/RVWd2Qq9
Now even though I don't have the "bankaccount" controller or models set up correctly yet, shouldn't it be at least attempting to go there and saving the stripe_account? Just making sure that's not the issue. But it appears it's failing because a new form reloads.
The API is successfully going through as well and the accounts are appearing within stripe, just not my own database.
What in my programming is wrong?

You can either use optional :true to resolve the error

#^ should be singular
OR
Assign the user_id in the create action like so
#stripe_account.user_id = current_user.id #add this line
Update:
undefined method `user_id=' for StripeAccount:0x001234f4c58692ae8 Did
you mean? user="
The error is because you don't have user_id column in stripe_accounts table. Generate a migration that will do the job for you
rails g migration add_user_id_to_stripe_accounts user_id:integer
and do rails db:migrate

Error on rendering show action

I am trying to render show action by passing parameters, but the show page is not being rendered when there are no users signed in. This is my controller:
class QrCodesController < ApplicationController
def show
#user = User.find_by_qr(params[:id])
if #user.nil?
redirect_to root_path
end
end
end
and this is my view:
This is the qr-code page of <%= #user.fname %> <%= #user.lname%>
However, the show page is perfectly rendered when any user is signed in.
The rails server also shows perfectly rendered show action:

Please Help.
EDIT:
This is the link that triggers the show action:
http://localhost:3000/qr_codes/9M9JZLiemrNdS_g90mZ14w
Since #user is equal to # when you print it, it is clearly not equal to nil and the redirection is not happening. You need to either change the code in find_by_qr to return nil if not found, or determine what other way that that method is using to represent not found, and change your conditional to use that.
Try this instead:
#user = User.find_by_qr(params[:id])
if #user
respond_to do |format|
format.html
end
else
redirect_to root_path
end
