问题 I want to load data from csv file into SQlite database. My code is : Model: db.define_table('data_table', Field('Title',requires =IS_NOT_EMPTY()), Field('Link',requires =IS_NOT_EMPTY())) db.data_table.import_from_csv_file(open('mycsv'),'rb') Controller: def index(): query=((db.data_table.id)) fields = (db.data_table.id, db.data_table.Title, db.data_table.Link) headers = {'data_table.id': 'ID', 'db.data_table.Title': 'Title', 'db.data_table.Link': 'Link', } default_sort_order=[db.data_table.id

问题 I try to create an application in web2py framework. By default web2py server has Transfer-Encoding: Chunked header for response, but in that case when target remote web application sends GET request to my app it could get only first string of text from requested page (from file's content that displayed on page).

问题 My code: def return_post: form = SQLFORM(db.post) for c in form: form1= post.body form2 = form1.split() return dict(form2=form2) In view: {{=form2}} I get the error that form2 is not defined. The above is the actual code. I had actually posted this from the Samsung tab and could not get the curly brackets. 回答1: You have to use =form2 within curly braces, not parenthesis. {{=form2}} Change it and try again. If using your tablet, try copy-pasting the above line. That should work. 来源： https:/

问题 I'm using AngularJS (mainly the client side) and web2py (mainly the server side)together in an app. I have an issue now. At a point of the program, I use AngularJS to get some data from the client and these data are store in an AngularJS variable. I planed to use $http.post to submit these data to database directly, but it didn't work due to cross-orign problem. Right now I'm trying to pass these data(they are in JSON format) back to web2py and let web2py insert these data to database.
