Question

How to convert integer to string in a query in GAE?

Answer 1

+1 A:

Is this Python? I'm assuming so. In which case, use int():

p = Pet.all().filter('score =', int(self.request.get('searchquery'))).fetch(10)

Hi, Thanks. But can you explain why this works. Intuitively, I would think to use str()?

Zeynel 2010-10-17 03:27:56

@Zeynel: [`int()`](http://docs.python.org/library/functions.html#int) converts things to ints. [`str()`](http://docs.python.org/library/functions.html#str) converts things to strings. What about that doesn't make sense?

Matt Ball 2010-10-17 03:29:14

This is how I was reasoning: I enter an integer into the search form; but the "searchquery" in the query needs to be string. So I was trying to convert "searchquery" to string. But obviously this is wrong; because int() the way you had it works. Thanks anyway; I appreciated.

Zeynel 2010-10-17 03:38:22

@Zeynel: when you type **anything** in, you're entering strings. It's not magically an int just by being a string consisting solely of `[0-9]`.

What Matt Ball said, request.get returns a string but the filter logic requires an int as I assume you have made 'score' an IntegerProperty in the Pet class.

Answer 2

A:

I think you need to convert an Integer to a string as far as i understand therefore use str(int) in this case : p = Pet.all().filter('score =', self.request.get(str('searchquery'))).fetch(10)

You've got it backwards, my friend. `str()` converts things to strings.

Matt Ball 2010-10-17 03:25:41

And `str('searchquery')` is a no-op, `'searchquery'` is already a string.

Jason Hall 2010-10-17 14:13:40

@Jason : yes but here in this question Zeynel assumes 'searchquery' is an integer therefore he needs to convert it to a string.

Keshan 2010-10-17 15:05:42

@Keshan Then you want to do `str(self.request.get('searchquery'))`

Jason Hall 2010-10-17 17:56:56

ah ok sorry for the mistake :) Thanks Jason...

Keshan 2010-10-17 18:04:16

`self.request.get()` will never return anything but a string.
