    <p>I have a series of python modules written which are held in the same directory and I am having trouble with an ImportError.</p> <p>The three modules I am using are <code>draw_menu.py</code>, <code>errors.py</code> and <code>file_operations.py</code>.</p> <p>In <code>errors.py</code> I requires a list of error codes, I am using a custom method defined in <code>file_operations.py</code> to open a file containing the codes therefore I am using <code>import file_operations</code> just below the she-bang (above the class definition).</p> <p>In <code>file_operations.py</code> I use a method defined in <code>error.py</code> to print error messages upon errors (e.g. file not found etc.). I therefore <code>import errors</code> in the same way here.</p> <p>The above has been working fine but when I come to using <code>draw_menu.py</code> which uses a file to define the options in an ascii menu (therefore I am using <code>import file_operations</code>) an ImportError is encountered. </p> <p><code>ImportError: cannot import name file_operations</code></p> <p>I understand that this is because the 'import tree' if you like flows as follows:</p> <p><code>draw_menu</code> &lt;- <code>file_operations</code> &lt;- <code>errors</code> &lt;- <code>file_operations</code></p> <p>It is important that each module can be used individually, why is this an issue and how can I overcome this without removing <code>import file_operations</code> from <code>errors.py</code>?</p> <p>Thankyou </p> <p>Tom</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.
