    <p>Logical flow of the scraper: article links extracted from an XML feed are put into a list called self.raw_html. The following [simplified] method is then called to filter out the container the articles are in and remove text from the given articles:</p> <pre><code>def fetch_article_contents(self): for article in self.raw_html: self.css_selector_type == 'class': soup = article.find(self.html_element, self.css_selector) soup = soup.get_text() self.article_html.append(soup) return self.article_html </code></pre> <p>This works well on most feeds, but on two notable exemptions (Forbes and Official Google Blog) fails with the following message when get_text() is called:</p> <pre><code>AttributeError: 'NoneType' object has no attribute 'get_text' </code></pre> <p>My first logical step in debugging was to see what was returning a NoneType object, so I stuck a <code>print type(soup)</code> right before <code>soup = soup.get_text()</code>. I found:</p> <pre><code>&lt;class 'bs4.element.Tag'&gt; (25 times, condensed to save space) &lt;type 'NoneType'&gt; </code></pre> <p>This also strikes me as strange because there are currently 29 articles in <code>self.raw_html</code> when fetching the Forbes XML feed as verified by len(self.raw_html) when the class is initalized.</p> <p>The Google Official Blog returns:</p> <pre><code>&lt;class 'bs4.element.Tag'&gt; (just once this time) &lt;type 'NoneType'&gt; </code></pre> <p>and in reality has 25 fetched articles.</p> <p>What is the problem I'm encountering? Thanks!</p>

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.
