Customize django admin. Problem with no-model views - python

Im trying to create a extra view in django admin, on the left navbar. This view will be responsible for uploading a file, which will be parsed in some function (in future i would like to render result of this parsing in admin page). This file wont be saved in database, so there wont be a model. Is there any possibility to add a view to django admin (left navbar) which dont have a model? I was reading a lot, and could find a solution. What i have done for now:
Created a class which inherits from AdminSite. I tried to implement get_app_list method, but variable self._build_app_dict(request) was empty array, and this means, method couldn't find a installed aps. I wanted to add new object to app_list variable, to render it on website.
Tried to override a admin templates, but couldnt render it. I tried to override app_index.html which i put on folder: app_name/templates/admin/app_index.html
Here is my code, which ofc doesnt work:
class MyCustomAdmin(AdminSite):
def get_app_list(self, request):
"""
Return a sorted list of all the installed apps that have been
registered in this site.
"""
app_dict = self._build_app_dict(request)
breakpoint()
app_list = sorted(app_dict.values(), key=lambda x: x['name'].lower())
for app in app_list:
app['models'].sort(key=lambda x: x['name'])
return app_list
def get_urls(self):
from django.conf.urls import url
urls = super(MyCustomAdmin, self).get_urls()
urls += [
url(r'^my_custom_view/$', self.admin_view(MyCustomView.as_view()))
]
return urls
class MyCustomView(View):
template_name = 'admin/app_index.html'
def get(self, request):
print('fefef')
return render(request, self.template_name, {})
def post(self, request):
pass
admin_site = MyCustomAdmin()
admin_site.get_app_list(AdminSite.get_app_list)

Django 1.9 : Passing arguments from urls.py to a class view

I am creating a small web application as a mini project of mine to learn the Django framework. I'm on Version 1.9.4, on OS X. I'm trying to pass a string in the URL that will be sent to a class-based view, and it will return a different template based on the URL. To my knowledge, doing (?P) will allow the input of dynamic text. \w is for characters, and writing <name> will pass it as a variable. Is this configured right, or is this is not the correct way to do it?
The reason I'm concerned is that the Django documentation uses method views, while I am using class-based views.
urls.py
from django.conf.urls import url
from . import views
app_name = 'xyz'
urlpatterns = [
url(r'^create/(?P<ty>\w+)$', views.ArticleView.as_view(), name='article-form'), #.as_view() to turn Class into View
]
views.py
class ArticleCreate(View):
l = {
'weapon': WeaponForm,
'map': MapForm,
'operator': OperatorForm,
'gadget': GadgetForm,
'skin': SkinForm
}
ty = ty.lower()
template_name = 'xyz/create_article_form.html'
def get(self, request):
return render(request, self.template_name)
def post(self, request):
pass
The arguments that are being passed to the url should be "catched" within the view inside the relevant function, for example:
def get(self, request, ty):
ty = ty.lower()
return render(request, self.template_name)

How to convert a Django ListView to work on the admin site?

I have a list view (for the admin site) that uses a template as follows:
class UserImageListPendingView(ListView):
model = UserImage
queryset = UserImage.objects.filter(status=ImageBase.PENDING)
template_name = 'userimage_list_pending.html'
context_object_name = 'userimage_list'
paginate_by = 5
#method_decorator(staff_member_required)
def dispatch(self, *args, **kwargs):
return super(UserImageListPendingView, self).dispatch(*args, **kwargs)
Although this works there are problems with putting the URL in urls.py:
urlpatterns = [
url(r'^admin/app/pendinguserimages/?$', login_required(
UserImageListPendingView.as_view()),
name='pendinguserimages'),
...
]
...as this stops the redirection working properly.
I did try to define the URL through admin.py:
def get_admin_urls(urls):
def get_urls():
return patterns('',
url(r'^app/pendinguserimages/?$',
UserImageListPendingView.as_view(), name='pendinguserimages'),
url(r'^app/checkuserimage/(?P<pk>[0-9]+)/?$',
userimage_check, name='checkuserimage'),
...
) + urls
return get_urls
admin_urls = get_admin_urls(admin.site.get_urls())
admin.site.get_urls = admin_urls
... but there was an error when reversing the checkuserimage URL.
How would I go about converting this view to fit in better with the admin site, but still use the template?
I didn't need to rewrite the ListView afterall. After defining the URLs in admin.py instead of in urls.py, all I needed to do was put "admin:" in front of the name when reversing the URL in the template, as follows:

Django Admin Custom Pages and Features

I'm (new to) working in Django and would like to create two features that do not rely upon models/database tables. The basis of this app is as a web-based wrapper to a Python application.
The features are:
I would like to be able to load a ConfigObj text file into a page and edit it's configuration prior to saving again.
I would like to be able to call command line python/bash scripts and display their output on a page - like exec in PHP.
At the moment I'm working on simple custom admin pages without model as described here:
Django admin, section without "model"?
Would this be the right direction to go in? I'm not sure proxy tables apply as the features I desire have nothing to do with any data.
So far I have looked at is it possible to create a custom admin view without a model behind it and a few other links. At the moment I have:
main/urls.py
url(r'^admin/weectrl', include('weectrl.urls')),
which links with weectrl/urls.py
from weectrl import views
urlpatterns = patterns('',
(r'^admin/weectrl/manage/$', weectrl_manage_view),
(r'^admin/weectrl/config/$', weectrl_config_view),
)
which points to weectrl/views.py
def weectrl_manage_view(request):
r = render_to_response('admin/weectrl/manage.html', context, RequestContext(request))
return HttpResponse(r)
def weectrl_config_view(request):
r = render_to_response('admin/weectrl/config.html', context, RequestContext(request))
return HttpResponse(r)
The current error message is name 'weectrl_manage_view' is not defined
Ok, found something that works.
In the main url.py
url(r'^admin/weectrl/', include('weectrl.urls')),
In app/urls.py
urlpatterns = patterns('',
url(r'^config/$', views.config, name='config'),
url(r'^manage/$', views.manage, name='manage'),
)
and in app/views.py
def config(request):
context = ""
return render(request, 'weectrl/config.html', context)
def manage(request):
context = ""
return render(request, 'weectrl/manage.html', context)
html files are in app/templates/app/...

Override signup view django-allauth

I am asking user to fill extra fields with custom form. And in one of the fields, I have to let user choose multiple hierarchical tags. For this, I need to pass the tags from a view to the template signup.html
from classes.Tags import Tags
from django.shortcuts import render_to_response
from allauth.socialaccount import views as signup_views
def signup_view(request):
tags = Tags()
parameters={}
all_tags = tags.get_tags()
parameters['all_tags'] = all_tags
response = signup_views.signup(request)
return response
And in urls.py, I added this line before the allauth urls include line.
url(r'^accounts/social/signup/', 'mainapp.signup_views.signup_view', name = 'account_signup'),
url(r'^accounts/', include('allauth.urls')),
What I need is that I need to add all_tags to the response so that I can access it from the template. How do I do that?
This link has some details on using your own signup form. IMO, you can define your own form (eventually with a custom widget for the tags) and use it directly, without having to mess with the view.
Otherwise, #PauloAlmeida is correct. You could inherit a new class off SignupView with something like:
class MySignupView(SignupView):
def get_context_data(self, **kwargs):
ret = super(MySignupView, self).get_context_data(**kwargs)
ret['all_tags'] = Tags.get_tags()
return ret
I'd rather use the custom form approach as it won't mess up the urls.py.

django haystack - how to use with current view having some context

I have a view that puts some context and renders the template from this context. I want view display all the things if no search query is there, and show searhed things, if anything searched.
class MyCurrentView(View):
def get(self, request):
data = { 'users': User.objects.all() }
return render_to_response("mytemp.html", ..
urls.py:
url(r'^search/$', MyCurrentView.as_view())
Now, I am integrating this with SEarchView like this:
class MyCurrentView(SearchView): (If u observe, I subclassed SEarchView).
template = 'mytemp.html'
def get(self, request):
data = { 'users': User.objects.all() }
return render_to_response...
def get_context_data(self, ...):
print "....this should print" #But not printing. So, unable to add data
return data
urls.py:
url(r'^search/$', MyCurrentView.as_view())
# as_view() gave me error, so I did MyCurrentView() , may be thats y, get_context_data not calling.
Will provide more information if necessary.
New Django-style class based views were added via PR #1130 to django-haystack:
https://github.com/toastdriven/django-haystack/pull/1130
You can now use search views like you normally would with django (see changes in pull request).
from haystack.generic_views import SearchView
class MySearchView(SearchView):
def get_context_data(self, **kwargs):
# do whatever you want to context
