10,440 PointsWhat does ...methods['POST']) mean?
Kenneth Love : 'I want this to only be accessible, if you post to it...'?
@app.route('/save', methods=['POST'])
What does this mean and where does methods=['POST'] come from?

there are two http methods GET and POST. I think of it as GET being getting something from the url to be used in the view and POST posting values to the view. So if a user visits yourdomain/save/2 your getting the value 2 from the url which could be an ID of some sort and is GET request. POST is normally values coming from a form. In flask if your posting values from a form for example your route should look like this or you will get the error 'not allowed'.
@app.route('/save',methods=['GET','POST'])
def save():
#if you want to execute code only when the request is post you can do this
if request.method=='POST':
#do something.
If you are using WT forms then it is quite smart and you wont need the request.method line.

10,440 PointsOk. I kind of understood the POST bit. Still struggle to understand GET. I tested it in two ways, using GET and POST. So when I have only POST as a method, I get a new view (what function returns) if I submit a value through the form. For example, if we take a case from the video tutorial; I get to the next view (route) 'Saved!' if I submit a value in the form (this is with having POST as a method). If I have GET as a method, my submission through the form does not work, it works only if I add a route manually into URL.
Not sure if that makes sense but why do we need GET method and when should we use it?
