Stupid Google Stupid App Stupid Engine

[jvmakin]

So I have a page on google app engine that can take information and I can print that out on the page. And I have a python program that can align sequences. I cannot, however, make them work together. Does anybody know where in the google app engine code you can stick methods that modify the information collected? Slash show them on the final page?

Are you following the examples in the Google docs? What does your app engine code look like so far? Are you getting any kind of error?

I think it should be possible to just import your sequence alignment code, and then call it from your app engine code, so, something like...

from my_sequence_aligner import align_sequences
...
    def post(self):
        submitted = cgi.escape(self.request.get('content')))
        sequence1, sequence2 = submitted.split_or_process_or_something()
        result = allign_sequences(sequence1, sequence2)
        self.response.write(result)

@jvmakin Based on what we were working on in office hours you should do something like this:

• Once you've passed all the parameters in from the HTML form and have them in your Sequence Aligner class you should pass those to the function that does the alignment.
• That function should return the alignment
• Pass the alignment as a parameter back to you MainApplication class (just like you were doing with sequence1 and sequence2).
• In your MainApplication class, you should format your alignment and then pass that along as a template variable to be rendered in HTML

You may want to adopt some simple formatting to pass your matrix around. Something like

1,2,3,4:5,6,7,8:9,10,11,12 

for

1 2 3
4 5 6
7 8 9

You can just split and parse that up to format as an HTML table to pass along as a template variable.

Everyone else: This is just one approach based on what we worked on in office hours. You may be doing it differently, but that does not mean it is incorrect.

Thank you! I will try new things. :)
