python - Flask redirects on GAE -

-

Hello I am using a flask on Google App Engine (http://flask.pocoo.org/) I have a low code 

  @ app.route ("/ edit.html", methods = ['GET', 'POST']) def (): If request.method == 'GET': form = ImageForm () return render_template ('edit.html', title = u'Add ', form = form) if request.method ==' POST ': image = Image () form = ImageForm (Request Form , Image) if form.validate () and request.files ['image']: form.populate_obj (image) if request.files ['image']: image.file = request.files ['image']. () Image.put () Return Redirect (url_for ("edit", id = image.key ()) Other: return render_template ('edit.html', title = u'Add ', form = form) @app ( AD): image = Image.get (id) form = ImageForm (request.form, image) route ("/ edit / & lt; id & gt; Html", methods = ['GET', 'POST'] ) Return to Reader_Template ('edit.html', title = u'Edit ', form = form)   
 But the browser sent me to a given URL  
  Return Redirect (url_for ("edit", id = image.key ()))   
 I get a message:  
 
 Image status: 302 content Type: text / html; Charset = utf-8 Location:  http: // localhost: 8080 / edit / agtyb3VnaC1kcmFmdHILCxIFSW1hZ2UYDQw.html  Content-Length: 299  
 Redirect ...  
 Redirecting ...  
 You must be automatically redirected to target URLs: /edit/agtyb3VnaC1kcmFmdHILCxIFSW1hZ2UYDQw.html. If the link is not clicked on.   
 I do not understand what's wrong with my code?   
 
 
 Output the text in response before the feedback of the FLAC framework is something in your code (it seems That's like printing 'image') - Maybe there's a print statement somewhere in your code. Consequently, the header tries to produce flasks instead of interpreted as part of the body of the reaction.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
