I know I figured this out sometime, but can't remember now. How does one make a variable that is automatically accessible to all views?
<div><br>
</div>
<div>I mean like the <font face="monospace">current_user</font> variable provided by Flask-Admin: it automatically calculates <font face="serif">current_user</font> and makes it available to the view for each request, without having to manually define it each
time.</div>
<div><br>
</div>
<div>Basically, make it so that instead of...</div>
<div><br>
</div>
<blockquote type="cite">
<div><font face="monospace">@app.route('/example')</font></div>
<div><font face="monospace">def example():</font></div>
<div><font face="monospace"> my_var = something()</font></div>
<div><font face="monospace"><br>
</font></div>
<div><font face="monospace">@app.route('/example/2')</font></div>
<div><font face="monospace">def second_example():</font></div>
<div><font face="monospace"> my_var = something()</font></div>
</blockquote>

<div>...it automatically calculates <font face="monospace">my_var</font> without having to manually define it in each view.</div>

</div>
<div>Okay, I hope that was clear. And thanks in advance!</div>
