    <p>I'm trying out the shelve module and I'm running into some trouble. My intention is to have one module call a function in a second one which will modify a file inside a shelve. I made a prototype (below) that simply tries to set a variable to something stored in the shelve and print that object.</p> <p>When I attempt to do this I get the following attribute error:</p> <pre><code>AttributeError: 'module' object has no attribute 'User' </code></pre> <p>My guess is it doesn't realize my 'User' class exists but I'm unsure of the reason why. File1 calls the same function as File2 does in it's main function and it correctly works in that instance. I'd appreciate any help with this problem, I'm confused on what the issue is.</p> <pre><code>import SE_ex2 SE_ex2.cacheTest() </code></pre> <hr> <pre><code>import shelve cache_users = shelve.open("usersTest.cache") class User(object): def __init__(self, name, num): self.name = name self.num = num def __str__(self): return "Name:{0}, Num={1}".format(self.name, self.num) def cacheTest(): obj = cache_users[ "user_red" ] print obj if __name__ == "__main__": cacheTest() #Used for creating the cache for the first time # red = User("red", 11) # green = User("green", 22) # blue = User("blue", 33) # # cache_users['user_red'] = red # cache_users['user_green'] = green # cache_users['user_blue'] = blue # print "DONE" </code></pre> <hr> <p>Full Traceback:</p> <pre><code>Traceback (most recent call last): File "C:\Users\akaGrim\My Documents\Aptana Studio 3 Workspace\ShelveTest\SE_ex1.py", line 3, in &lt;module&gt; SE_ex2.cacheTest() File "C:\Users\akaGrim\My Documents\Aptana Studio 3 Workspace\ShelveTest\SE_ex2.py", line 14, in cacheTest obj = cache_users[ "user_red" ] File "C:\Python27\lib\shelve.py", line 122, in __getitem__ value = Unpickler(f).load() AttributeError: 'module' object has no attribute 'User' </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.
