  1. POStripe payments, adding price from another model into payment method
    text
    copied!<p>I have added Stripe payment to my app to handle registration payments for events, the form is on the event show page so the method is in the events controller but I have created a registration model. My issue is trying to get the price of the event into the <code>save_with_payment</code> method inside the registration model(<code>total_price</code>).</p> <p>Any ideas? I have tried <code>attr_accessible :price</code> but with no luck.</p> <h2>Event Controller</h2> <pre><code>def show @event = Event.where(:slug =&gt; params[:slug]).first @registration = Registration.new end def payment @registration = Registration.new(params[:registration]) if @registration.save_with_payment RegistrationMailer.admin(@registration, @event).deliver RegistrationMailer.delegate(@registration, @event).deliver redirect_to root_path flash[:success] = "Thank you for registering for &lt;% @event.title %&gt;" else redirect_to root_path flash[:error] = "We're sorry, something went wrong" end end </code></pre> <h2>Registration Model</h2> <pre><code>def save_with_payment if valid? charge = Stripe::Charge.create({ amount: total_price, ##I can declare a integer here instead of a method and it works currency: "gbp", card: stripe_card_token, description: email }) save end rescue Stripe::CardError =&gt; e end def total_price @event.price = price price end </code></pre> <h2>Routes</h2> <pre><code>match 'registration' =&gt; 'events#show', :via =&gt; :get match 'registration' =&gt; 'events#payment', :via =&gt; :post </code></pre> <h2>View</h2> <pre><code>&lt;%= simple_form_for [@registration], :method =&gt; :post, :url =&gt; registration_path do |f| %&gt; &lt;%= f.input :first_name %&gt; &lt;%= f.input :last_name %&gt; &lt;%= f.input :email %&gt; &lt;%= f.input :job_title %&gt; &lt;%= f.input :company %&gt; &lt;%= f.input :stripe_card_token, as: :hidden %&gt; &lt;div class="input card_number"&gt; &lt;label for="card_number"&gt;Card number&lt;/label&gt; &lt;%= text_field_tag :card_number %&gt; &lt;/div&gt; &lt;div class="input card_cvc"&gt; &lt;label for="card_code"&gt;Security code (CVC)&lt;/label&gt; &lt;%= text_field_tag :card_cvc %&gt; &lt;/div&gt; &lt;div class="input card_dates"&gt; &lt;label&gt;Card expiration date&lt;/label&gt; &lt;%= select_month nil, { add_month_number: true }, { id: "card_month"} %&gt; &lt;%= select_year nil, { add_year: Date.today.year, end_year: Date.today.year + 15 }, { id: "card_year"} %&gt; &lt;/div&gt; &lt;%= f.button :submit, "Register", class: "button" %&gt; </code></pre>
