    <p>I'm using Google's OAuth2 API in a project, using Omniauth to enable creating the initial accounts with little effort, but in order to use the APIs I need to refresh the access_token since they're only valid for an hour, but I'm having an issue updating the expires_at value when I refresh the token.</p> <p>Here's the code I'm using for requesting the token refresh:</p> <pre><code>require 'oauth2' class Identity &lt; ActiveRecord::Base belongs_to :user def refresh_access_token case self.provider when "google" client = OAuth2::Client.new OAUTH_KEYS_CONFIG['google']['client_id'], OAUTH_KEYS_CONFIG['google']['client_secret'], { :site =&gt; 'https://accounts.google.com', :authorize_url =&gt; "/o/oauth2/auth", :token_url =&gt; "/o/oauth2/token" } response = OAuth2::AccessToken.from_hash(client, :refresh_token =&gt; self.refresh_token).refresh! self.update_attribute(:access_token, response.token) self.update_attribute(:expires_at, Time.at(response.expires_at)) end end end </code></pre> <p>I get an <code>undefined method 'change' for 1359936923:Fixnum</code> error on the final update_attribute line for :expires_at (I split it from the line above to try and figure out the issue).</p> <p>I've tried both the above <code>update_attribute</code> call, and also a simple <code>self.expires_at = response.expires_at</code>, with and without <code>Time.at</code> casting but all combinations result in the same error.</p> <p>The :expires_at attribute is a Timestamp datatype. I've checked the <code>response</code> variable, it contains the timestamp correctly as far as I can tell:</p> <pre><code>--- !ruby/object:OAuth2::AccessToken ... expires_in: 3600 expires_at: 1360019618 options: :mode: :header :header_format: Bearer %s :param_name: bearer_token ... </code></pre> <p>Stack trace</p> <pre><code>activerecord (3.2.11)

    2. COSorry, the error reports to be on the second update_attribute call, for :expires_at. Without that line the action finishes successfully, but of course then my code will constantly refresh the access_token, since it won't ever get told that it's not expired.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
