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

Question

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?

Answer 1

Validation failed: User must exist

You can either use optional :true to resolve the error

#stipe_account.rb
belongs_to :user, optional: true
            #^ 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
