best aproach to pass an email from the url to a view?

[dk]

I put the Email that I got from a form into the url (I am using the url as a variable to store the email)

and look like this

http://127.0.0.1:8000/polls/vote/thank/a...@b.com/

url:

url(r'^vote/thank/(?<your_email>   #here should be RE catching the email    )$', views.thank),

view:

def thank(request, your_email=None):
    c = {"thanks_body": "thanks_body view"}
    c["his_email"] = your_email
    return render(request, "thanks.html", c)

I am having issues to try to come up with a RE to grab the email

I try http://stackoverflow.com/questions/201323/using-a-regular-expression-to-validate-an-email-address

using it on my url

such

url(r'^vote/thank/(?<your_email>^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$ ', views.thank),

 and I still don't catch it, I think because I am just copy pasting but in the url string should be arrenge diferntly?

I was reading about a  get function that can make a quary on the url like a dictionary?  any example on how to use it?

thanks,  (I order a book for RE  =)  just to be able to udertand a little bit more   )

Try adding a capital P after the ? in your named capture group.

Otherwise your capture group does not place its value in the your_email variable as you are expecting:

(?P<your_email>...

Check out the Python re module syntax for an explanation:

I think you're trying too hard here. Regexes for email are usually concerned with *validation*, ie checking in a form that the thing typed into the "email" field looks like an actual email. But that is not, or should not be, a consideration in a URL: at this point the email has already been validated, and all you want to do is to send it to the next page. So you probably just want to grab everything after the `thank` part:

'^vote/thank/(?<your_email>.*)$'

To be honest though, this is something I wouldn't even try to catch in the URL at all. Instead, pass it as a querystring parameter, so the URL would be in the format "/vote/thank/?email=f...@bar.com" and you get it in the view as `request.GET['email']`.

    if request.method == "POST":
        form = polls.forms_DK.NameForm(request.POST)
        if form.is_valid():
            your_email = form.cleaned_data["your_email"]
            ratio = str(form.cleaned_data["ratio"])
            adress = "thank/?email="+your_email+"/" # here I make the URL
            return HttpResponseRedirect(adress)
    else:
        form = polls.forms_DK.NameForm()
    django.setup()
    all_restaurants = Restaurant.objects.all()
    return render(request, "vote_form.html", {"all_restaurants": all_restaurants, "form": form})

def thank(request, your_email=None): # I don't need your_email=None
    c = {"thanks_body": "thanks_body view"} # I can rearenge the dictonary
    remail = request.GET["email"] #here I pick up the email
    c["thanks_body"] = remail
    return render(request, "thanks.html", c)

if you want to keep a value from one request to another, check the
Session feature. In short, it works (almost) like a persistent
dictionary private for each web user.
