Body
You didn't specify any error messages, but it's most likely that you're doing <code>fuctions.one()</code> - actually calling the one() function of that module before the Button is created. It's simply fixed by removing the () part - when you specify a function without (), you are passing a reference of the function object. Also keep in mind the scope of the <code>code_entry</code> variable - if you were using it as a module level global before (or function local, if <code>one()</code> was inside the same function as your <code>ttk.Button</code> call), it won't be available when you move it to a new namespace without <code>code_entry</code>. To solve this you should pass <code>code_entry</code> as a parameter to the callback without calling <code>one()</code> at first. The usual approach for this is creating a lambda - essentially creating a function that works on the same scope of the original <code>one()</code>, having access to variables like <code>code_entry</code>, but also calling a function in a different module. <pre><code>ttk.Button(mainframe, text="1", command=lambda: functions.one(code_entry)) </code></pre> Note that this is basically the same as: <pre><code>def some_anonymous_function(): functions.one(code_entry) ttk.Button(mainframe, text="1", command=some_anonymous_function) </code></pre> Both examples create a function object and pass that object as reference - the <code>functions.one()</code> call of the lambda is actually inside the body of the lambda function, to be called later by tkinter. Of course you also have to redefine one() to accept this new parameter: <pre><code>def one(code_entry): code_entry.insert(END,"1") </code></pre>

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.
