Getting Started with Python web py (10)-Implementing forum Registration

When a user wants to publish an article in a forum, it is necessary to register an account before they can log in and publish articles. So let's move on to the previous example to implement the registration function.
Above the underlying code in the previous example, the code example is attached below:
http://blog.csdn.net/caimouse/article/details/79343362

First to add a URL to the main program entry file forum.py the registered page, as follows:

URLs = (
'/', ' Index ',
'/register ', ' register ',
)

The addition of '/register ', ' register ', in this line, is to implement the Association of the Registration class, and then to create the Register class register:

Class Register:
    def get (self): return
        titled_render (' register '). Register ()

    def POST (self):
        try:
            i = Web.input ()
            user_id = model. User (). New (I.email, I.username, I.password)
        except Exception as E:
            print (e) return
            Titled_render (). Failed (' mailbox or account number already exists, please <a href= '/register ' > Registration </a> ')
        else:
            if user_id:
                # Set Cookies
                Web.setcookie (' user_id ', str (user_id), settings. Cookie_expires)
                raise Web.seeother ('/user/%d '% user_id)

In the registration class implementation of two methods, the first is a get method, mainly display a page, let the user input data, I do not know whether you remember the previous example, is it "the introduction of Python Web py (5)-to write the data of the Web page to the database", the realization is the same. The second method is post, which is to write the data submitted by the page to the database.
This line of code titled_render (' register '). Register () is to call the template register.html to render the display, let the user enter data, display the results as follows:


When the user presses the Submit registration button, the Post method will submit data to the server, you can use Web.input () to obtain the appropriate data, where to obtain the email address, user name and password, and finally through the model in class user to add to the database to save.

Call the new function as follows:

def new (self, email, username, password):
        Pwdhash = hashlib.md5 (Password.encode (' Utf-8 ')). Hexdigest ()
        return Db.insert (' Users ', Email=email, Name=username, Password=pwdhash,
                         picture= '/static/img/user_normal.jpg ', Description= "")

In this function, first call the Hashlib Library's MD5 algorithm to sign the password, so that the original password can not be seen from the database, followed by the call to the Db.insert to perform the database operation, the registration data into the database table, so that the entire registration process completed. If you successfully register, you open the Personal information page. Otherwise, you will be prompted with an unexpected error (Titled_render (). Failed), such as duplicate registration, and so on.

register.html Template:

$def with () <form id= "register" action= "" method= "POST" > <table> <tbody> <tr> <td& Gt;<label for= "Email" > Email </label></td> <td><input type= "text" id= "email" name= "email"/& Gt;<span class= "Validate_tip" ></span></td> </tr> <tr> <td><label fo R= "username" > account </label></td> <td><input type= "text" id= "username" name= "username"/>&lt ; span class= "Validate_tip" ></span></td> </tr> <tr> <td><label for= "pas Sword "> Password </label></td> <td><input type=" password "id=" password "name=" password "/><s" Pan class= "Validate_tip" ></span></td> </tr> <tr> <td><label for= "PASSW Ord_again "> Password confirmation </label></td> <td><input type=" password "id=" password_again "name=" password _again "/><span class= "Validate_tip" ></span></td> </tr> <tr><td><input type= "Submit" id= "Registe" R_btn "value="/></td></tr> </tbody> </table> </form>

The failed.html template file is as follows:

$def with (error)

<p>$:error</p>
