<div dir="ltr">Hi Arthur!<br><br>Good point about documentation, I think we should change it as you said.<br><br>Regarding the exception, this is the standard Python behavior. Consider this example:<br><br>x = 10<br>def func():<br> print(x)<br> x = 5<br><br>func()<br><br>If you run this example, you'll get the exception "UnboundLocalError: local variable 'x' referenced before assignment" in the first line of the function. This is because when Python parses the program text, it sees "x = 5" assignment and assumes that the x is a local name. It then uses name x as a local name during all function body, even before "x = 5" line. You cannot use name x as a global name in the beginning of the function and as a local name in the end.<br><br>See for example: <a href="http://stackoverflow.com/questions/9264763/unboundlocalerror-in-python">http://stackoverflow.com/questions/9264763/unboundlocalerror-in-python</a><br><a href="http://stackoverflow.com/questions/21456739/unboundlocalerror-local-variable-l-referenced-before-assignment-python">http://stackoverflow.com/questions/21456739/unboundlocalerror-local-variable-l-referenced-before-assignment-python</a><br><br><br>Regards,<br>Alexander<br><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Oct 27, 2014 at 9:27 PM, Goldberg, Arthur P <span dir="ltr"><<a href="mailto:arthur.p.goldberg@mssm.edu" target="_blank">arthur.p.goldberg@mssm.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div>Hi guys</div>
<div><br>
</div>
<div> Generally, pony has been great. Thanks!</div>
<div><br>
</div>
<div>However I think this is a bug. I ran the attached program, and it generates this call stack. The error is reported in line 202 but it is actually in line 203. I know that the ID in 203 overrides the db.entity class of that name, but I would think that
the error does not exist until line 203.</div>

<div> Also, I have a documentation suggestion.for example, your documentation says:</div>

<div> whereas it is more convenient to say:</div>
</div>
<div><br>
</div>
<div>for p in Product.select():</div>
