    <p>Sounds like the internals of your class should probably have a <a href="http://docs.python.org/2/library/logging.html#logger-objects" rel="noreferrer"><code>Logger</code></a> and that you'll want to add a <a href="http://docs.python.org/2/library/logging.handlers.html#filehandler" rel="noreferrer"><code>FileHandler</code></a> to the <code>Logger</code>. You might want to consider just using a factory method that creates <code>Logger</code>s and adds the handler instead of implementing your own class. You may need to create the directories that hold the log files. See <a href="https://stackoverflow.com/questions/273192/python-best-way-to-create-directory-if-it-doesnt-exist-for-file-write">this answer</a> for advice on creating directories.</p> <p>Edit:</p> <p>I don't think you need to write your own <code>Logger</code> class. Python's <code>logging</code> module has all the pieces you need. You probably just need a factory method. The key to realize is you need to create two separate, completely independent logging objects. You do this with <code>logging.getLogger</code>, and any time you pass it a different name, it gives you a different logger. You can use anything you want for the logger's name. For sure, you want to stay away from <code>basicConfig</code> for what you're doing. It's designed to be something simple for people who just want one <code>Logger</code> not doing anything too special.</p> <p>I think this demonstrates the functionality you're after. The key is create two different loggers with different handlers. Then use them separately. Keep in mind that my second call to <code>logging.getLogger</code> doesn't create a new logger; it gets the one we set up initially in <code>setup_logger</code>.</p> <p>log_test.py:</p> <pre><code>from __future__ import absolute_import import logging def setup_logger(logger_name, log_file, level=logging.INFO): l = logging.getLogger(logger_name) formatter = logging.Formatter('%(asctime)s : %(message)s') fileHandler = logging.FileHandler(log_file, mode='w') fileHandler.setFormatter(formatter) streamHandler = logging.StreamHandler() streamHandler.setFormatter(formatter) l.setLevel(level) l.addHandler(fileHandler) l.addHandler(streamHandler) def main(): setup_logger('log1', r'C:\temp\log1.log') setup_logger('log2', r'C:\temp\log2.log') log1 = logging.getLogger('log1') log2 = logging.getLogger('log2') log1.info('Info for log 1!') log2.info('Info for log 2!') log1.error('Oh, no! Something went wrong!') if '__main__' == __name__: main() </code></pre> <p>Sample run:</p> <pre><code>C:\temp&gt;C:\Python\27\python.exe logtest.py 2013-06-12 02:00:13,832 : Info for log 1! 2013-06-12 02:00:13,832 : Info for log 2! 2013-06-12 02:00:13,832 : Oh, no! Something went wrong! </code></pre> <p>log1.log:</p> <pre><code>2013-06-12 02:00:13,832 : Info for log 1! 2013-06-12 02:00:13,832 : Oh, no! Something went wrong! </code></pre> <p>log2.log:</p> <pre><code>2013-06-12 02:00:13,832 : Info for log 2! </code></pre>

    1. COI am new to logging module and I see even if I am giving different filename in basicConfig there is only one file created. Let me tell what my problem is Suppose there is a class A, class B and file C. C has a main function where I create object of class A and B. Class A logs should go to A.log file and Class B log should go to B.log file. I dont want any log of A to come B.log or viceversa. So can I create a common logger class and use this class in both A and B. Any example with psuedocode would help

    2. COI have added the generic class which I wanna create. Can you tell me what am I doing wrong?

    3. CO+1. `setup_logger()` might be a better name (getLogger() creates loggers if necessary). You might want `l.propagate = False` to avoid passing messages to ancestor loggers. Logger's name should probably be derived from a class name (a period in logger's name is special that is how logger hierarchy is created i.e., `.` in a name should be avoided unless explicitly desired (you could [use `logging_tree` to visualize it](https://pypi.python.org/pypi/logging_tree))).

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.
