Django - custom non-model form field in admin panel
I would like to find a way to add another choice field next to actions form in my django admin panel. Here is my admin class: class InactiveSiteAdmin(SiteAdmin): change_list_template = 'admin/change_list_inactive.html' list_display = ('is_active', 'thumb', 'name', 'show_url', 'get_desc', 'keywords','category', 'subcategory', 'category1', 'subcategory1', 'group') fields = ('name', 'url', 'id', 'category', 'subcategory', 'category1', 'subcategory1', 'description', 'keywords', 'date', 'group', 'user', 'is_active', 'date_end',) readonly_fields = ('date', 'date_end', 'id') list_display_links = ('name',) actions = [activate_sites, activate_sites1, ] def get_queryset(self, request): return Site.objects.filter(is_active=False) def response_change(self, request, obj): return redirect('/admin/mainapp/site/{}/change/'.format(obj.id)) def has_add_permission(self, request): return False Here is top of my admin panel page: I am looking for way to add another choice field next to admin actions button. Something like: New form field is not related to any model. Choices are stored in database (I use django-constance). I tried to create new form in forms.py - for example with simple charfield: class EmailForm(forms.Form): email_form = forms.CharField(max_length=20) but I don't have any idea how can I use it in my admin template. -

Is there a Django way of comparing the results of a test to a fixture?
I'm trying to understand fixtures and unit tests in Django. I can successfully load a fixture and use the data in my unit test. What I want to do is compare the results of the test to a second fixture, fixture_2, which represents how the data should look. Here's a step-by-step of what I am talking about: Import fixture_1, generating the initial test data. Run the test on the data, changing it. Somehow compare the results of the test to fixture_2. Is there a way to do step 3? Should I somehow overwrite the test database with fixture_2 and do the assertions from there, or is there a way of comparing the test database to a fixture? -
Django 1.10 Template Renders Nested HTML Tags Outside Their Parent
I am a bit puzzled by the following behavior of the Django templates, which prevents me from successfully styling the output. Namely, I have the following template: <article class="article {% if article.is_featured %} featured{% endif %} {% if not article.published %} unpublished{% endif %}"> {% if not detail_view %} <div class="post-preview"> <a href="{% namespace_url 'article-detail' article.slug namespace=namespace default='' %}"> <h2 class="post-title"> {% render_model article "title" "" "" "striptags" %} </h2> {% if article.lead_in %} <h3 class="post-subtitle"> {% if not detail_view %} {% render_model article "lead_in" "" "" "truncatewords:'20'|striptags" %} {% else %} {% render_model article "lead_in" "" "" "striptags" %} {% endif %} </h3> {% endif %} </a> <p class="post-meta" style="margin-bottom: 0;"> Posted by {% include "aldryn_newsblog/includes/author.html" with author=article.author %} on {{ article.publishing_date|date:"F d, Y" }} </p> <p class="post-meta" style="margin: 0"> <h4 style="display:inline-flex">Categories:</h4> {% for category in article.categories.all %} <a href="/articles/category/{{category.name|lower}}">{{ category.name }} {% if not forloop.last %}, {% endif %}</a> {% endfor %} </p> <p class="post-meta" style="margin: 0"> <h4 style="display:inline-flex">Tags:</h4> {% for tag in article.tag %} <a href="/articles/category/{{tag.name|lower}}">{{ tag.name }} {% if not forloop.last %}, {% endif %}</a> {% endfor %} </p> </div> <hr> {% endif %} {% if detail_view %} <!-- <h3>Testing template!

How to make a website work with Django development server?
I understand that this is never to be done. But I have a situation where I need to get something done real quick. I have to do a website where may be 200 people would register for an event. I need to present a simple registration form. Very basic functionality, register and view list of registrants. Very few hits. It would be live for about a month or so. I know a little bit of Django which can allow me to put together this thing quickly. However, I have only worked with the Django development server. My problem is setting up Apache to work with Django. I understand that, for Django, I need mod_wsgi installed. I have a VPS but mod_wsgi is not installed. I have asked my hosting provider to install it for me. Even if I can get mod_wsgi installed, it appears that it may take me some time to configure it and it may take a while. I have the following questions. Can I run this website on the Django development server? Will it hold up for very light traffic? If I do, how do I get traffic to go from port 80 to the development server … -
trouble using python requests to POST to django 1.8 server
I tried using session and grabbing the cookie. s = requests.Session() s.get(myurl) csrf = s.cookies['csrftoken'] The get had status_code 200 as expected. Then I first tried just a post on the session hoping that the session would do magic. (yeah I know better) r = s.post(myurl, json=mydata) which gives a status_code of 405. And yes, before I forget I have the django settings CSRF_HEADER_NAME='HTTP_X_CSRFToken' CORS_ORIGIN_ALLOW_ALL = True and my view function is marked with @csrf-exempt as well. The view function is known to accept post from my Angular frontend as long as I have 'X-CSRFToken=csrf' where csrf is as in the above setting. So I tried r = s.post(myurl, json=mydata, headers={'X-CSRFToken':csrf}) as well with the same result of 405. I read that it might help to set the referer to the url so I tried that as well. r = s.post(myurl, json=mydata, headers={'X-CSRFToken':csrf, 'Referrer: url}) and still got 405. So what is the correct way to make this work? -

django-allauth mutli step signup form
I'm using pydanny/coockiecutter-django for a custom project, and I needed to build a custom multi-step signup for customers. django-allauth is a custom authentication tool inside cookiecutter so after some researching and reading the docs I found out how to customize allauth SignupForm and allauth-SignupView so it will fit my needs, but I have some problems, but please bare with me it's a long question. This custom signup needs to use some custom fields for state, zip-code and phonenumber. For this I'm using django-localflavor and for phonenumber-field I'm using django-phonenumber-field. Process of extending signup in django-allauth is a bit different. You can not define normal ModelForm field with class Meta rather you need to do it like this. This is two-step custom signup form. from django import forms from allauth.account.forms import SignupForm from localflavor.us.forms import USStateSelect, USPSSelect from ..models import User class CompanySignupStepOneForm(SignupForm): """ TODO: Custom Signup. :returns: TODO """ company_name = forms.CharField(max_length=225, required=True, strip=True) company_street_address = forms.CharField(max_length=225, required=True, strip=True) city = forms.CharField(max_length=225, required=True, strip=True) state = USStateSelect() zip_code = USPSSelect() def save(self, request): user = super(CompanySignupStepOneForm, self).save(request) company_user = User( step_one=user, company_name=self.cleaned_data.get('company_name'), company_street_address=self.cleaned_data.get('company_street_address'), city=self.cleaned_data.get('city') ) company_user.save() return company_user.step_one Step-two custom Signup Form: from django import forms from allauth.account.forms import SignupForm … -
postgresql query returned more than one row Django/heroku

I tried doing distinct(), that didn't work. -
Using Django with Firebase
I'm using Django, because I was familiar with it, and firebase together. Obviously the firebase db doesn't connect directly with Django, so I have written custom models like so: class MyModel(object): def __init__(self, var): self.var = var def db_snapshot(self, snapshot): snapshot_value = snapshot.val() var = snapshot_value['var'] return self def to_any_object(self): return { 'var': var, } So everything works out pretty well for creating model objects, I also have some custom get(), save(), create() functions as well. Because I'm not using models or a django db, I'm also not using forms... So my question is, do I need to use forms? Obviously I know its not necessary, because I'm doing it currently, but my question is, am I exposing my customers to any potential security flaws? Is there anything I should know? I do plan on implementing the django rest framework later on, and at that point I would either move to mongodb or figure out how to implement the drf with firebase. I know what I'm doing isn't conventional, and I would appreciate ANY input. I have no degree and I self taught myself everything. Sincerely, Denis Angell -
How can i update class variable by calling a class method from a base class
I am developing a package for my testing purpose. In this package all my database queries are placed. a simple version of package is shown below. I am not using django ORM in my app since it is slower. I am using MySQLdb for accessing database. package.py from django.test import TestCase dbcon='connector' class testcase(TestCase): flag_user=[] @classmethod def setUpClass(cls): global dbcon dbcon=MySQLdb.connect(host=dbHost,port=dbPort,user=dbUser,passwd=dbPasswd,db=dbname) super(testcase, cls).setUpClass() cursor = dbcon.cursor() sql=open("empty.sql").read() cursor.execute(sql) cursor.close() views.MySQLdb=Mockdb() @classmethod def tearDownClass(cls): dbcon.close() def user_table(self,username=username,email=email): cache=[username] self.flag_user.append(cache) cmpdata=(username,email) insert_table(tablename_user,cmpdata) def delete(self,table): delete_table(tablename) self.flag_user=[] tests.py from package import testcase class showfiles(testcase): def setUp(self): print "setup2" self.user_table(username='vishnu',email='vishnu@clartrum.com') def tearDown(self): print "teardown2" self.delete("user") def test_1(self): print "test dbtest link feature" def test_2(self): print "test health/errorfiles with valid device" self.user_table(username='vishnu',email='vishnu@clartrum.com') The insert_table in package execute insert operation in sql and delete_table deletes the entry from user. empty.sql creates tables for the database. Actually when i run the tests, finally the flag_user should contain only [['vishnu']]. But i get [['vishnu'],['vishnu']] and this is because delete function in teardown doesn't updating the value. I think this is due to class property or something? Can any one suggest me a way to do this? -
Django Inheritance and One-To-One issues
I've devised the following relationships: class Security(models.Model): .... class MajorSecurity(Security): inner = models.OneToOneField(Security, on_delete=models.DO_NOTHING) class MinorSecurity(Security): ... I then put together a saved object like so: s = MinorSecurity.objects.create(...) c = MajorSecurity.objects.create(inner=s) Then when I access c.inner I only see that it is a Security and not a MinorSecurity What do I have to do to get django orm to recognize what subclass the one-to-one relationship is pointing to? The idea is that a MajorSecurity can have another MajorSecurity in it, or a MinorSecurity... so it needs to be flexible, which is why I chose to set the class to Security instead of a specific subclass. I was hoping that there is a way for the ORM to differentiate which subclass it is. I'm assuming the type also needs to be stored within the record of the Security. -
Django - Does not insert null and producing ValueError

Formatting and incrementing a Django form in HTML
OK so I have a running form in Django that updates the model and displays this on the page, but I was hoping to better format it. What happens is that the page displays all data imputed in the form. What I want to do is to numerically list it. This is what I have in my home.html right now: {% extends 'base.html' %} {% block body %} <div class="container"> <h1>Home</h1> <form method="post"> {% csrf_token %} {{ form.as_p }} <button type="submit">Submit</button> </form> {% for post in posts %} <h2>Object:{{ post.post }}</h2> {% endfor %} </div> {% endblock %} So say I have data "a", "b", and "c". It would display itself as Object: a Object: b Object: c If I added d to the form, it would add Object: d What I'm hoping to do is add an increment to this so it displays itself as Object 1: a Object 2: b Object 3: c And add d as Object 4: How would I go about implementing this? Another thing I wanted to know is whether I can change the "Post:" comment next to the form. Right now my form displays itself with "Post:" at the left side. Is there … -
Django Building A Restful API
I want to build a Django Api App that allows me to render multiple variations of data. For example take a look at my code: urlpatterns = [ url(r'nav-func$', views.FundNavApi.as_view(option='nav_func')), url(r'fund_nav/(?P<fund_id>[0-9]+)$', views.FundNavApi.as_view(option='fund_nav')) ] Views.py class FundNavApi(APIView): option = 'default' model_class = NAV fund_id = None def get(self, request, format=None): if self.option == 'nav_func': res = self.nav_func print(res) elif self.option == 'fund_nav': print(self.kwargs['fund_id']) return Response("Hi") @staticmethod def nav_func(): querysets = NAV.objects.filter(fund__account_class=0, transmission=3).values( 'valuation_period_end_date').annotate( total_nav=Sum(F('outstanding_shares_par') * F('nav'))).order_by('valuation_period_end_date') df = read_frame(querysets, coerce_float=True) df.loc[:, 'valuation_period_end_date'] = pd.to_datetime(df.valuation_period_end_date) df.loc[:, 'timestamp'] = df.valuation_period_end_date.astype(np.int64) // 10 ** 6 df.loc[:, 'total_nav'] = df.total_nav df = df.round(0) print(df[['timestamp', 'total_nav']].values.tolist()) return df[['timestamp', 'total_nav']].values.tolist() As you can see, I want to use the same model but manipulate the data differently based on the url. So, I use the option='' parameter as a way to tell the controller what to render. So I have two questions: The nav_func function doesn't seemed to be called when res = self.nav_func is being run. The print statement isn't displaying anything. Is this the correct approach? Like is this what professionals do in terms of building an API that renders different variations of data while using one type of model? -
Django: display multiple objects on a single page
I have a lot of data from my fantasy basketball league displayed at index.html When I click a player name, I am taken to that player's single season's statistics. What I want to happen, when I click a player name, is for all of that player's career statistics to show up, not just a single year. What's the best method for going about doing that? I've been stuck on this for about two weeks now, lol Note: each 'player' object contains a separate "game_id" that belongs to each real-life player (e.g. each player object in this list of Aaron Brooks objects has the same "game_id"), but I haven't been able to figure out how to use it yet!

How to redo tables without dropping it in Heroku
Every time I change columns name or length or anything, I need to drop the entire database in heroku. This is after doing makemigrations and migrate. On local, it works fine. I don't need to adjust.

What is another way where I don't need to drop the entire database every single time i make an adjustment? -
How to setup URLs with subfolders in Django?
I have the following setup of links that allow me to navigate through the different URLs of my Django web app, however, I am missing something that is making my web app to throw a Page not found (404) error. This is the scenario: I have the following structure of folders and html files: personal_website (web app name) -no_results_graphs (folder) -graph_no_results.html --test_no_results_table (subfolder) --table_no_results.html -results_graphs (folder) -graph_results.html --test_results_table (subfolder) --table_results.html header.html home.html When I navigate from: graph_no_results.html -> graph_results.html = OK graph_results.html -> graph_no_results.html = OK table_no_results.html -> graph_no_results.html = OK table_no_results.html -> table_results.html = OK graph_no_results.html -> table_no_results.html = NOT OK graph_results.html -> table_no_results.html = NOT OK And I encounter the following errors: Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/graph_results/test_no_results_table/table_no_results/ Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/graph_no_results/test_no_results_table/table_no_results/ The setup of the views was set as the following: url(r'^test_no_results_table/table_no_results/$',views.tickets_current_week), url(r'^test_results_table/table_results/$',views.tickets_current_week, name='current_week'), What am I missing or why my pages cannot be found? -
