Page not found error in Django REST framework tutorial
I am doing the Django REST Framework Tutorial, and I got to the part when they add the view for an individual snippet (view snippet_detail, tutorial 2). When I start the server and point the browser to url http://127.0.0.1:8000/snippets, it returns the 3 snippets I have created before (ids:1,2,3), fine. At url http://127.0.0.1:8000/snippets/2, it returns only the snippet 2, perfect. But when I try http://127.0.0.1:8000/snippets/1, it raises a Page not found error: Using the URLconf defined in tutorial.urls, Django tried these URL patterns, in this order: ^ ^snippets/$ ^ ^snippets/(?P<pk>[0-9]+)$ ^admin/ The current path, snippets/1/, didn't match any of these. I don't understand why snippets/1 doesn't match the second url pattern. Can someone please clarify this error and help me overcome this. -

how to get absolute value of interval in django F expression?
I'm trying to sort by date difference between now and recorded date of a model instance.

How do I insert hidden input field in a Django / Bootstrap crispy form, before the password field?
I have a Django / Bootstrap crispy form for registering a new user: from django import forms from crispy_forms.helper import FormHelper from crispy_forms.layout import Layout, Fieldset, ButtonHolder, Submit class UserForm(forms.ModelForm): password = forms.CharField(widget=forms.PasswordInput( attrs={'autocomplete':'off',})) def __init__(self, *args, **kwargs): super(UserForm, self).__init__(*args, **kwargs) self.helper = FormHelper(self) self.helper.layout = Layout( Fieldset( '', 'username', 'first_name', 'last_name', 'email', 'password' ), ButtonHolder( Submit('submit', 'Submit', css_class='button white') ) ) The problem is that the browser autocomplete fills in the email and password fields. The HTML generated by Django crispy forms around the password is as follows: <div id="div_id_password" class="control-group"> <label for="id_password" class="control-label requiredField"> Password <span class="asteriskField">*</span> </label> <div class="controls"> <input name="password" autocomplete="off" required="" id="id_password" class="textinput textInput" type="password"> </div> </div> Now I understand that turning autocomplete off does not work. So I would like to do the usual trick of inserting a hidden field just before the password via Django crispy forms, so that the result is: <div id="div_id_password" class="control-group"> <label for="id_password" class="control-label requiredField"> Password <span class="asteriskField">*</span> </label> <div class="controls"> <input type="text" style="display:none;"> <input name="password" autocomplete="off" required="" id="id_password" class="textinput textInput" type="password"> </div> </div> Is there a nice way to insert this HTML via Djano crispy forms, unless there is another way to prevent the autocomplete? -
Form not submitting the user input to the corresponding url, Django
I was following this video tutorials and got lost inbetween. The app has a form where one can click radio buttons in the existing list to mark it as favorite. On submit, page should reload and display something like "your favorite" along with the list that has been marked favorite and rest same way. This feature exactly works as intended from the admin page of Django but not from the html form. I guess post request is not being sent as intended.

Show a logged in user their own information from a database model
I am relatively new to Django, and web development in general. Basically, I'm trying to build a website with two types of users: customers, and suppliers. Both the customers and suppliers have user accounts (containing a username, email, and password) created using Django's built-in 'from django.contrib.auth import login -forms.Form' and stored in the table 'auth_user' in my mySQL database. But, the suppliers can also create a more detailed profile (name, bio, images etc) which is created using a 'forms.ModelForm' called 'SupplierSignupForm' and stored in a separate table to 'auth_user', called 'home_suppliersignup'. What I want to happen is, when a supplier is logged in, they can click on their 'my profile' link in the header and be taken to their profile located in the 'home_suppliersignup' table in my database. Currently, I know how to call a logged in users ID from the table 'auth_user' using their session info, and then use that to link to their respective 'auth_user' profile: views.py user = request.user template <a href="{% url 'supplier_profile' id=user.id %}">My profile</a> urls.py url(r'^supplier-profile/(?P<id>[0-9]+)', supplier_profile, name="supplier_profile") But I don't know how to use this to pull up their information from another database table (i.e. home_suppliersignup). Any help would be much appreciated! -
