    <h2>Ruby Stripe</h2> <p>I'm trying to interface with the Ruby Stripe library, specifically with the subscription_update function as documented here: <a href="https://stripe.com/docs/api#update_subscription" rel="nofollow">https://stripe.com/docs/api#update_subscription</a></p> <p>This is what the syntax looks like:</p> <pre><code>c = Stripe::Customer.retrieve("cus_2BWdBuTAE3HboP") c.update_subscription(:plan =&gt; "basic", :prorate =&gt; true) </code></pre> <h2>Implementing Rails Model</h2> <p>I'm implementing a rails model that can interface with the ruby library. Since this api will update my subscription with nil values (that will over ride the defaults), I need a function that will crawl the writable attributes and create an array of only the attributes that are not nil that I can pass to this update_subscription function.</p> <p>Here's what I have now:</p> <pre><code> def get_non_nil_update_attributes attributes = Array.new([ :plan, :trial_end, :quantity, :coupon, :prorate ]) return_attributes = {} attributes.each do |attribute| if !self.send( attribute ).nil? return_attributes[attribute] = self.send( attribute) end end return return_attributes end </code></pre> <p>I would like to just call this:</p> <p><code>c.update_subscription( mymodel.get_non_nil_update_attributes )</code> </p> <p>But I get an error that I'm not passing in the plan param. At the console my output if this function is:</p> <pre><code>[{:plan=&gt;"7"}, {:trial_end=&gt;"bla"}] </code></pre> <p>I know this is a simply ruby question but how do I make this output just <code>:plan =&gt; "7", :trial_end =&gt; "bla"</code> to pass into my function?</p>

    1. COIs the output you posted from `get_non_nil_update_attributes`, or from `update_subscription`?

    2. COThe output needs to come from the get_non_nil_update_attributes and be passed to update_subscription.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
