django forms render static text
I am using django form wizard to render a series of forms and in my last screen, I want to show the user a simple screen that says press the save button to continue. So, this last screen has no input elements. I, of course, need it to be part of the wizard workflow. I was wondering if there is a Form element that can be used for something like this or if there is some hack to basically just show this text. So basically I have something like: class FinalForm(Forms.Form): text = Forms.CharField(label="Press Save to update the record") def __init__(self, *args, **kwargs): super(FinalForm, self).__init__(*args, **kwargs) self.helper = FormHelper() # crispy-forms bit Here, of course, the CharField renders the text as a label and is an input field. Can it be done that we can have this form only contain some static text? The urls.py is declared as: url(r'^reviewrecord/(?P<pk>\d+)/$', views.ContactWizard.as_view([FirstForm, SecondForm, FinalForm]), name='reviewrecord'), -
How to modify wagtail CMS so that any user can post blog posts under their own blog
I have an existing website that is a Django App. I have installed Wagtail, and the Wagtail CMS is now accessible at www.example.com/cms. Wagtail is working correctly with my database, and all the existing users are visible when I go to settings and then users, in the wagtail CMS admin page. I want to use Wagtail to add blog functionality to my website. Requirements I want any user to be able to create a new blog and add posts to their blog. I want the blog created by a user to be visible at www.example.com/blogs/username/ How can I set Wagtail up to accomplish this? I have checked the documentation at http://docs.wagtail.io/en/v1.9/ but could not figure out where to start with my modifications. I have also installed the example blog project (https://github.com/wagtail/wagtaildemo) but I was also unable to figure out how to accomplish 1 and 2 above from this. Any complete answers, or general pointers, very welcome. -
Heroku seems to not use Django database?
I've got an app that works locally for me and has about ~50000 entires in an sqlite DB. The heroku app however, seems to have the same reaction searching for any day that I would have locally searching for data not in the database. So, I believe everything static is being served (pictures are static and are being served), and debugging in the JS console shows that the Django view is not returning data (because the JS function gets nothing). It also gives chrome something about loading unsecure scripts, and I have to turn of HTTPS to view the html/css/js properly. I think this is somewhat a seperate issue. These leads me to believe that Heroku does not have the database. How can I fix this or is there something else I can look into? Here is some code, I've added all Heroku recommendations: Views: def getTweets(request, tag): data = tweets.objects.filter(tag = tag).values('xcoord', 'ycoord', 'tag') return JsonResponse(list(data), safe=False) Model: class tweets(models.Model): id = models.AutoField(primary_key=True) tag = models.CharField(max_length=255, default=None) xcoord = models.CharField(max_length=40, default=None) ycoord = models.CharField(max_length=40, default=None) Settings: import os import dj_database_url # Build paths inside the project like this: os.path.join(BASE_DIR, ...)

Django: How can I provide different users a different subset of options for the same ManyToManyField
The Question: How can I provide different users a different subset of options for the same ManyToManyField in the admin, and have each user's selections only affect their options? The Scenario: I am building an interactive map web app. There can be many Maps. There can be many MapItems. MapItems can be on many Maps and Maps can have many Map Items. Thus a ManyToMany relationship. Each Map has an owner, and I want only the owner of a Map to be able to add or remove MapItems from his/her Map. Here are the relevant parts of my models: class Map(models.Model): # Omit owner = models.ForeignKey(User, default=1) class MapItem(models.Model): # Omit map = models.ManyToManyField(Map, default=None, blank=True) MapItem.map is represented by a <select> on the MapItem admin interface: <select multiple="multiple" id="id_map" name="map"> <option value="1">Bob's Map</option> <option value="2">Sally's Map</option> </select> I want Bob to only have the option to select/deselect Bob's Map and not even see Sally's Map as an option. I have been able to filter the options that are displayed in the admin <select> widget by overriding get_form() on the ModelAdmin. def get_form(self, request, obj=None, **kwargs): kwargs['form'] = MapItemAdminForm form = super(MapItemAdmin, self).get_form(request, obj, **kwargs) form.base_fields['map'].queryset = form.base_fields['map'].queryset.filter(Q(owner=request.user) | Q(groups__in=request.user.groups.all())) … -

instantiate django modelform with POST data and instance and prefix
I am instantiating an instance of a modelform. The modelform holds data for an object that will be updated, not created new. I want to populate the form with POST data and include an instance of prior data. So: myform = MyForm(request.POST, instance=instance, prefix=myPrefix)The catch is that the POST data for this modelform has a prefix. When I call .is_valid() on the modelform the fields from the instance are not recognized because they don't have the prefix. Can somebody help? Thanks! -

Django migrations not detecting all changes
I have the following models. BaseClass1 and BaseClass2 are abstract models used by models. In this case, the model AdBreak is used by a viewset and a serializer. When I run python manage.py makemigrations, the changes on AdBreak model is detected. The model AdBreakStatus is not getting created.

Django get the Model name using ORM's related field name
I have a string like this order__product__category__description which is a related expression of my Django's model structure Now I have a model called Shipment field = 'order__product__category__description' Here description is a column name of table/model Category. Here comes the question, just by having this model Shipment and this field string order__product__category__description how do I find these models Order, Product, Category. My use-case is I need to store all the field_names of Category in a list. Any idea on how to connect the dots? having left with just two details Shipment & that field string. First thing comes to mind is to split by __ and to come up with a list like this ['order','product','category'] and to iterate the model _meta based on the field name. Any other elegant ways would be appreciated. -

Django model inheritance: override restrictions in child classes
I will try to abstract my problem: I need to create two model classes for IPv4 and IPv6. I want to do it via inheritance; namely, to create a model class, and then to inherit from this class, but with the additional (different) limit for each of the child classes: class IP(models.Model): ip = models.GenericIPAddressField() class Meta: abstract = True class IPv4(IP): ip = models.GenericIPAddressField(protocol='ipv4') class IPv6(IP): ip = models.GenericIPAddressField(protocol='ipv6') I'm not sure whether or not this is the correct way to do that, and I would like to know which problems might be caused due to such a model. -
Django - user restriction from getting access to same value

Using Django Restframework to create Single User Sign On
I am currently using the Django Rest Framework. However an external cloud service provider would require a SSO. I was browsing through some answers but didn't get anything helpful. I can authenticate the user for the api curl -X POST -d "email=useremail&password=password" 127.0.0.1:8000 I get the token back. Now i can make api requests. I read something about using SAML, however all the packages are outdated. I was thinking about rewriting the authentication() function, to take in the username and the token to verify the user and redirect him to the App Dashboard. To clarify an external Cloud Service is trying to log in a user into our APP with a direct link. I can't find a nice, clean approach to use here. I don't think i should use something like request.GET.get('username') request.GET.get('password') because i don't think that will be very secure. On the other hand the curl call is pretty much doing the same thing to get the token. Any Advice, Ideas? -
