How django LoginRequiredMixin use templates. How can we pass context_data to the login form template-CodePudding

How django LoginRequiredMixin takes templates. I cound not find anything how it is taking the templates.

I had added account folder inside templates and then LoginRequiredMixin is taking my template but how it is wokring and how can i pass a context data to the template of login form

CodePudding user response：

LoginRequiredMixin does not render anythings. This mixin just redirect to LOGIN_URL set in settings by default. You can ovveride the url directly in class with this mixin like this:

class MyView(LoginRequiredMixin, View):
    login_url = '...'

By default, login_url settings go to LoginView from django.contrib.auth.views and use the registration/login.html. So you can create a login.html in a registration directory in your templates dir for overriding just the default template used if you want

What I had done is to pass context data to LoginRequiredMixin Template is shown below. Whether is it a right approach?.

urls.py

path('login_url/', views.CustomLogin.as_view(),name='login'),

views.py

class SettingsPage(LoginRequiredMixin, TemplateView):
      login_url = '/login_url/'

class CustomLogin(TemplateView):
      template_name = 'login.html'

     def get_context_data(self, **kwargs):
         context = super(CustomLogin, self).get_context_data(**kwargs)
         context['redirect_field_name'] = 'next'
         context['redirect_field_value'] = self.request.get_full_path().split('=')[1]
    return context

<form   method="POST" action="/accounts/login/">
   {% csrf_token %}
   <input type="hidden" name="{{ redirect_field_name }}" value="{{redirect_field_value}}">

   <h4 >Login</h4> 
   <input  type="text" name="login" id="id_login">
   <input  type="password" name="password" id="id_password">    
   <button  type="submit" >Login</button>
</form>

Here it will automatically redirect to the redirect_field_value after login
