Server error appears again when adding an object. #76

Closed Mingzhao91 closed 8 years ago

Mingzhao91 commented 8 years ago

If I add an object with this address: http://127.0.0.1:8000/IAPTAssessmentmaster7/object/create#, the new object is successfully added to the collection. However, when adding an object with this address: http://127.0.0.1:8000/IAPTAssessmentmaster7/object/create?collection=1, I have a server error on the screen but there is on other information telling me what goes wrong. Could you guys help me with this issue? Thank you.

The link above is working fine for me. :(

When you run web2py, there should be two windows: the command line/terminal one and the server setup one. Is anything appearing in the command line/terminal one?

The server error occurs when the form is submitted for the second link. Google chrome only shows me the server setup window. There is no command line/terminal window for me and I am not sure how could I find it. The error link is: http://127.0.0.1:8000/IAPTAssessmentmaster8/object/create?collection=1#

OK. Think I've got it. Because the collection is being passed as both a url parameter and as a form POST parameter, the two were conflicting. This should be fixed by 4d9b27d.

(Specifically, if web2py finds two params with the same name it builds them into a list containing all the values, meaning that request.args['collection'] became ['1', '1'] - a list containing the two collection ids. Obviously this mucked up the database lookup.)

Not sure why the error handling disappeared though - I'll take a closer look at this.
