How to tell browser that the form was wrong and do not save password
I have a website with a login form. My problem is that every time this form is submitted, chrome suggests to save the password, even if it's incorrect The form: <form method="POST" action="" id='sign-in'> {% csrf_token %} <div class="form-group inner-addon"> <input name="txt_login_username" type="text" class="form-control" placeholder="Username"> <i class="fa fa-user fa-lg fa-fw" aria-hidden="true"></i> </div> <div class="form-group inner-addon"> <input name="txt_login_pass" type="password" class="form-control" placeholder="Password"> <i class="fa fa-key fa-lg fa-fw" aria-hidden="true"></i> </div> {% for message in messages %} <p class='alert alert-danger'>{{ message }}</p> {% endfor %} <button type="submit" class="btn btn-primary" name="btn_login">Log In</button> </form> -
How to add the logged in user's username with django
I am building a basic blog site with Django. Here's my views.py (AddPostView should be the relevant class) : class HomeView(ListView): model = Post template_name = 'community.html' ordering = ['-id'] class ArticleDetailView(DetailView): model = Post template_name = 'articles_details.html' class AddPostView(CreateView): model = Post form_class = PostForm template_name = 'add_post.html' #fields = '__all__' And here's my forms.py: class PostForm(forms.ModelForm): class Meta: model = Post fields = ['title','author', 'body', 'image'] widgets = { 'title': forms.TextInput(attrs={'class': 'form-control'}), 'author': forms.TextInput(attrs={'class': 'form-control'}), 'body': forms.Textarea(attrs={'class': 'form-control'}), } And models.py: class Post(models.Model): title = models.CharField(max_length=255) author = models.CharField(max_length=255, null=True) #author = models.ForeignKey(User, null=True, blank=True, on_delete=models.CASCADE) body = models.TextField() date = models.DateTimeField(auto_now_add=True) image = models.ImageField(null=True, blank=True, upload_to='images/qpics') def __str__(self): return self.title + ' - ' + self.author def get_absolute_url(self): return reverse('community') I do get that I have to remove the author from forms.py and change it accordingly into models.py and write a code in views.py but i can't find a working solution to my problem. Most of the answers online are for class based views and do not work for me. Little help will be appreciated. THANKS! -

DjangoAdmin: How to get the Add/Edit/Del buttons for an `AutocompleteSelect` form field
I'm using the AutocompleteSelect widget for a ForeignKey field. To do this, you override the ModelForm class like so: class XForm(forms.ModelForm): ... x = forms.ModelChoiceField( queryset=X.objects.all(), widget=AutocompleteSelect(x.field.remote_field, admin.site) ) However, by using this widget I lose the ＋ ✎ ✕ buttons that are available on the Django Admin interface for a Foreign Key field by default.
