How to get form.errors error text in view?

Question

Django

Good afternoon.
There was a task to drag an authorization form on each page of the site.
Made through the inclusion tag.

<form  method="post" action="{% url 'login' %}">
      {% csrf_token %}
      <tr>
          <td>
              <label class=""  for="name"></label>
              {{ auth_form.username }}
          </td>
          <td>
              <label class=""  for="pwd"></label>
              {{ auth_form.password }}
              <input type="submit" class="header__form_button" value="ОК">
          </td>
      </tr>
  </form>

But I don’t know how to return an error, of course, you can’t throw the form into any view.
It came to mind to use messages.

if request.method == 'POST':
        form = AuthUserFormPanel(data=request.POST)
        if form.is_valid():
            login(request, form.get_user())
            return HttpResponseRedirect(request.META.get('HTTP_REFERER'), '/')
        messages.add_message(request, messages.ERROR, form.errors)
        return HttpResponseRedirect(request.META.get('HTTP_REFERER'), '/')

However, form.errors returns:

<ul class="errorlist"><li>__all__<ul class="errorlist nonfield"><li>Пожалуйста, введите правильные имя пользователя и пароль. Оба поля могут быть чувствительны к регистру.</li></ul></li></ul>

I only need text

Please enter the correct username and password. Both fields can be case sensitive.

Do not parse this output?

Answer 1

Of course, you can’t throw the form into any view.

you can do this
https://docs.djangoproject.com/en/1.8/topics/auth/...
You make a function into which you pass request and return a dictionary of values ​​from it, depending on whether the user is logged in or not
You can make a mixin for CBV

Answer 2

the question, by the way, is a good one about getting errors. I also once wondered - to parse or not to parse :) it
is solved like this:

for field in form.errors:
               error[field]=form.errors[field].as_text()
