Update the question so it can be answered with facts and citations by editing this post. Closed 4 years ago . Now that Google allows Java on App Engine, I'm wondering what effect this has on a choice of web framework for App Engine. I realize Google provides the webapp framework which is pretty barebones. And the .96 version of django that's available for App Engine is restrictive.

问题 The q&a here (and the doc) describe the use of the format= argument to the define_table function. I have a problem getting that to work in a slightly more complicated case. I'm using web2py version (1, 99, 7, datetime.datetime(2012, 3, 4, 22, 12, 8), 'stable') , and Python 2.5.4 . (I'm using MySQL, but I assume that's irrelevant.) I have the following: 'Independent' (not a child) tables Institution and Person . Table Team is a child of Institution . Table Team_staff connects Person and Team

问题 I am currently working on a page where a user would select all the appropriate fields in a search form (html) which would than pass the values to the web2py query. I am having an issue with writing this query? I am wondering how to actually pass the values from HTML form to the web2py query to be run against the database? 回答1: When you submit a form to web2py (via GET or POST), all the form variables will be available in request.vars (for more on this, see the book sections on Dispatching and

问题 I've been trying to make URLs shorter. For example, change www.mydomainname.com/myapp/default/mypage to www.mydomainname.com/mypage I add the following code in routes.py under the web2py folder: routes_out=( ('.*:/sevenpeng/default(?P<any>.*)', '\g<any>'),) But this didn't work. The url still shows www.mydomain.com/default/mypage Am i missing something? Another problem, I deployed my website on google appengine, when I typed www.mydomainname.com, it directs to the right page, and the address

问题 I'm making an AJAX call to a python function. That function does a database query based on the information sent to the function. I can't work out how to get the variable that is sent to the function. I was using request.vars.variableName, and I know the function is valid, it's just not receiving the variable to use properly. How do I get POST sent variables from a python function, using web2py? ETA: This is the code I was using jQuery.ajax( {type: "POST", url: '../../Printed/printedballoons

问题 I have a thread doing a lot of CPU-intensive processing, which seems to be blocking out other threads. How do I limit it? This is for web2py specifically, but a general solution would be fine. 回答1: I actually just ended up diving into this issue not long ago, you wont be able to change the thread priority but there are ways around this. To give you a bit of background on the problem, in the cPython implementation CPU bound threads can cause other threads to starve because of the way the

问题 I am running web2py on a Windows machine. I'm working on an application, but it keeps erroring because it says the module I'm trying to use isn't installed. It is however installed in my local python install. How can I install modules so that web2py can recognize them? 回答1: web2py recognize any module you have in your local Python installation, unless you have a module with the same name under /modules folder of your application. If you are on windows I do not recommend the use of .exe

问题 Is there a web2py way of displaying images from a database table? Example: The model: db.define_table=('images',Field('picture', 'upload' )) The controller: def somefunction(): to get the image. How exactly should I "read" a picture from the database? The view: <img src="{{somefunction}}" /> 回答1: As is, your model will not store the image in the database -- instead, it will store the image on the filesystem, with its new filename stored in the database (in the 'picture' field).
