How to modify formset's forms in an iteration
As far as I know if you iterate over a list and update its element, you dont update list itself. list_var = ['a','b','c'] for l in list_var: l = 'x' print list_var it prints out ['a', 'b', 'c'], not X's Below code belongs to one of my project. if hasattr(self.model, 'get_disabled_always_fields'): for field in self.model.get_disabled_always_fields(): for form in self.formset_instance: try: form.fields[field].widget.attrs['readonly'] = True except KeyError as e: pass It updates the list element and it effect the list we were iterating. I didn't bother about it until below code didn't affect formset instances, it's almost the same. for form in self.formset_instance: if hasattr(form.instance, 'get_disabled_fields'): for field in form.instance.get_disabled_fields(): try: form.fields[field].widget.attrs['readonly'] = True except KeyError as e: pass They are almost identical except, First one,checked the attribute and started an outer loop, second one started to iterate over formset instance and, another loop inside that. Question is , why formset forms affected by for loop modifications , and why my second code block didn't affect. -

selecting specific object from list in django template
I am working with a formset_facotry and I am having an issue trying to figure something out. I have a list of users returned from a queryset in views.py file. I also have a list of forms that are created based on the number of objects returned from the list query. What I want to happen is that it selects the first object returned and display it before the first form that is to be displayed. Then grab the second object and displayed it right before the second form and so on... General idea behind it is the followoing: I want it to do something like this general template: header = 'Add record' + groupName if message: print(message) count = 0 for f in form: expenses[0] f.as_p count = count + 1 I want to grab a specific item based on the count within the loop: Here is the code that I have in the template: {% extends "base.html" %} {% block content %} <h2>Add expense - {{ currentGroup.name }}</h2> {% if message %} <p>{{message}}</p> {% endif %} <form action="." method="POST"> {% csrf_token %} {{ form.management_form }} {% with count=0 %} {% for f in form %} {% for expense … -
Anchor tag appending field to current url
I have a model with a field website_link class Partner(models.Model): website_link = models.CharField(max_length=120) And I access it in the template like so <div class="col-sm-3 col-sm-offset-1"> {% if instance.logo %}</a> <!-- website link just gets appended to the end of current url for some reason--> <a href="{{ instance.website_link }}"><img src='{{ instance.logo.url }}' class='img-responsive' alt=""></a> {% endif %} </div> When I call this in the template inside of an anchor tag the link navigates to the current url with the website_link appended to the end. So if instance.website_url = www.partnerone.com instead of the linke going to "www.partnerone.com" it goes to "http://127.0.0.1:8000/partners/partner-one/www.partnerone.com" -

Getting associated values from Python dictionary that is using lists

SAML SSO Authentication with Django REST Framework
I'm currently working on a AngularJS front-end and Django REST back-end. I've been using django-rest-auth in the past to authenticate my connections between the two, but I now have to integrate a SSO authentication using SAML. I've looked around and decided to use python3-saml, but any of the documentation and use case examples (for this package and any other) are applied for pure Django applications. I've been basing myself on OneLogin's django/flask guide and I tried making a custom Middleware that would catch my requests, but the implementation of the redirects provided by OneLogin does not work with REST call (obviously). I've also seen some people using the AUTHENTICATION_BACKENDS Django setting and I'm wondering if it's maybe more what I'm looking for. Thank you for any help. -

Blue footer in Gentelella Theme
I'm currently working with this fantastic theme. For context I'm using the django flavor django-gentelella. My problem is when I remove some elements from the side bar a blue footer appears, those elements are the following: Removing <div class="sidebar-footer hidden-small"> Blue Footer appears: Not removing the above class but if you remove some menu elements from the side bar when you click the hamburger to minimize the sidebar, blue footer again: I tried to replicate both scenarios on the demo: gentelella demo but only the first scenario can be reproduced, probably because the template is not being rendered. I'm not a CSS expert but if someone can help me I would really appreciate it.
