Re: Simple Login Problem

Hi,

If you type your password wrong, user will be None, and your code will then redirect to the "register" page.

If you press "back" after a successful login, the CSRF token will be out of date and the form won't work.

Are you caching any pages?

I have a django app but I having problems with my login views and logout views. I do not have a html template designated to handle user login/logout view.

Django project is configured as follows:

INSTALLED_APPS setting:

1. 'django.contrib.auth' contains the core of the authentication framework, and its default models.
2. 'django.contrib.contenttypes' is the Django content type system, which allows permissions to be associated with models you create.
3. 'django.contrib.sessions',
   

 MIDDLEWARE_CLASSES setting:

1. SessionMiddleware manages sessions across requests.
2. AuthenticationMiddleware associates users with requests using sessions.
3. csrf.CsrfViewMiddleware 

Using Django Template Language and Template inheritance. The login form is on the base template on other templates extends from this base template.

All my login attempts result in some of the views rendering the user info (username to welcome user back) while other views rendering the page as if the user is an anonymous user. If I try to login in again I get an error page stating that there is a missing csrf token or incorrect. Adding to this I have identified many instances where I have tried to logout and it does not seem to log me out because it is still showing the last user login info. For my base template I have hard coded the form (meaning not using Django Form class).

Can You identify the possible fault in how i am implementing the login and logout views?

 

 Here is a copy of my login and logout views

def members_login(request):

    if request.method == 'POST':

        password = request.POST['password']

        username = request.POST['username']

        user = authenticate(username=username,password=password)

        if user is not None:

            if user.is_active:

                login(request,user)

                return redirect('members:index')

            else:

                #inactive users required to re-register

                return redirect('members:index')

        else:

            #no account required to register to create one

            return redirect('members:register')

    

    else:

        #test if login is a regular get request then redirect

        return HttpResponseRedirect(reverse('members:index'))

def members_logout(request):

    logout(request)

    return redirect('members:index')

simplifying double decorators?

Hi,

I'm running into the situation where I have several views with the same set of decorators:

@login_required()
@user_passes_test(some_test_function, login_url='/', redirect_field_name=None)
def some_view(request):
    # some code
    return render(request, 'some_template.html', locals())

How would I go about combining the two (or more) decorators into a single decorator that can be used instead and retain the functionality?

IE: this:

@login_required()
@user_passes_test(some_test_function, login_url='/', redirect_field_name=None)

def some_view...

becomes abstracted to something like this:

@my_custom_decorator_with_redirects()

def some_view...

Re: Newbie help - running django-admin.py produces empty mysite folder

Hi,

Are there any error messages?

Is there already an existing mysite folder?

What method did you use to install django? Did you really install django 1.8, not 1.7?

Collin

Title says it all really. Have just installed Django 1.8, can test django version and get correct response so am *fairly* happy it's installed correctly. I have had Python 2.7 installed and been using perfectly for several months.

Altered the PATH variable as discussed so it points to correct directory.

However when I run...

django-admin.py startproject mysite

The mysite folder is created - but it is empty, none of the following is created...

mysite/
    manage.py
    mysite/
        __init__.py
        settings.py
        urls.py
        wsgi.py

All tips gratefully received!

Many thanks,

Re: Newbie: How to implement a app/module, which I can include from my html?

Assignment tags are my favorite.

@register.assignment_tag
def get_categories():
    return Category.objects.all()

{% get_categories as categories %}
{% for category in categories %}
{{ category }}
{% endfor %}

so it would be something like:

in category-lists.html
{% load those_categories %}

The usual way would be to write a custom template tag that fetches the objects and puts them into the template context.

Re: Problem implementing django-sslserver

Hi,

A few things.

The stacktrace looks like it's getting gibberish. Maybe your cert and key don't match?

When I try, I can't get it to listen on a different port number. (It looks like you're trying to have it listen on 8020)

Why not have apache (or nginx) handle the SSL for you?

Collin

Any suggestions as to what is going on and how to fix this.

We are running the dev server with a separate Apache server acting as a proxy.

The comnmand line is

$ python manage.py runsslserver --certificate /path/to/certificate.crt --key /path/to/key.key  ip_adress:8020

Re: Python: Assign variable in if statement?

Hi guys,

coming from php I am wondering if there is a way to do something like this in Python/Django:

if variable = get_a_value_from_function():
  new_stuff = variable


Of course I can use

variable = get_a_value_from_function()
if variable:
  new_stuff = variable



But is there a shortcut similar to php?


Not as such. Python intentionally didn't include assignment within

statements (mostly conditionals) to avoid the common issue of

assignments-instead-of-equality bugs.

If `new_stuff` has a default value, you could always write.

    new_stuff = some_function() or new_stuff

which will reassign `new_stuff` to itself if `some_function()` returns a

falsy value. If you need a more complex conditional body than just an

assignment, you'll need the long one.
