How do I get the highlight tag to dynamically detect and display the field(s) which contains a query match in Haystack?
I'm trying to create a search results page with django-haystack and elasticsearch backend, and it's working just fine in most cases, but I'm trying to account for the following edge case in a way that respects DRY. Let's suppose I have the following setup: apps/myapp/models.py from django.db import models class MyModel(models.Model): title = models.CharField() fieldA = models.Charfield() fieldB = models.Charfield() fieldC = models.Charfield() apps/myapp/search_indexes.py from haystack import indexes from .models import MyModel class MyModelIndex(indexes.SearchIndex, indexes.Indexable): text = indexes.CharField(document=True, use_template=True) title = indexes.CharField(model_attr='title') fieldA = indexes.CharField(model_attr='fieldA') fieldB = indexes.CharField(model_attr='fieldB') fieldC = indexes.CharField(model_attr='fieldC') def get_model(self): return MyModel templates/search/includes/myapp/mymodel.html {% load highlight %} <div class="result"> <h3><a href="{{ result.object.get_absolute_url }}">{{ result.object.title }}</a></h3> <p>{% highlight result.object.fieldA with query max_length 200 %}</p> </div> templates/search/indexes/myapp/mymodel_text.txt {{ object.title }} {{ object.fieldA }} {{ object.fieldB }} {{ object.fieldC }} As you can see in my mymodel.html template, I'm assuming that my query matched the contents of fieldA because I'm passing fieldA to the highlight tag. What if my query matched the contents of fieldB, but not fieldA? How do I get the highlight tag to dynamically detect and display the field that contains a match for my query? -
Django Ajax Form Works but Throws 500 (Internal Server Error)
I've researched this to death, but have not found exactly what I need to get the last part of my form completed. I have a simple 2-field form in my footer for newsletter signup. I am utilizing an inclusion_tag since I need to include the form on every page. The form works; with a couple of hitches, for arguments sake, it works, I hit submit and the email is sent to me. The problem is that I am getting a 500(internal server error) in console on the ajax url. I am assuming that its not really supposed to redirect to the url, but rather just process the form. Below is my code; I hope someone can easily point out my issues. Thanks. Inclusion Tag @register.inclusion_tag('includes/cta_form.html', takes_context=True) def footer_newsletter_signup(context): title = 'Newsletter Signup' form = CTASignupForm() context = { 'form': form, 'title': title, } return context Ajax $('#sendSignupForm').click(function (e) { e.preventDefault(); var mForm = $('#signupForm').serialize(); console.log(mForm); $.ajax({ type: 'POST', url: '{% url 'pages:cta_signup' %}', data: mForm, success: function (data) { $("input").val('') }, error: function (data) { $("input").addClass('error') } }) }) cta_form.html <form action="{% url 'pages:cta_signup' %}" method="POST" id="signupForm"> {% csrf_token %} {{ form.name }} {{ form.email }} <button class="btn btn-black no-margin-bottom … -

Using dokku run to dump data from Django
I'm trying to run python manage.py dumpdata ... within a Dokku app, but have not been able to get things to work. I'd like to occasionally dump the database so that I can replicate it on a development machine. Here is what I've tried so far: # Creates 20161207.json with 'python manage.py dumpdata app1 app2 app3' as the first line $> dokku run myapp 'python manage.py dumpdata app1 app2 app3 > /app/storage/db_dumps/20161207.json' # Dumps a bunch of json to the terminal $> dokku run myapp 'python manage.py dumpdata app1 app2 app3' # Of course, I can then save the output... $> dokku run myapp 'python manage.py dumpdata app1 app2 app3' > ~/db_dump.json # but I'd rather put this in shared storage for the sake of staying organized Any thoughts on why the first command doesn't work?

How do I control the order of form fields in Django?
Given that I have a generic form like this: from django import forms class TimesForm(forms.Form): hours = forms.DecimalField() description = forms.CharField() topic = forms.CharField() And I want to render this form in html, what is the best way to dynamically control the order of appearance? In other words, the user should be able to control the order in which those input fields are displayed on the screen. While I was able to iterate through the fields like this: {% for field in form %} {{field}} {% endfor %} I did not find a proper way to control the order of appearance of the input fields. How do I best do that? -

How can I safely look at the request body in a Django REST framework Authentication?
I've implemented a webhook. The caller provides a shared secret. They concatenate the request URL and body, sign it with the secret, and provide the signature in a header. To validate the signature, I need to repeat the process and compare the signature that I get to the one that the caller got. I'm using Django REST framework. I'm checking the signature in a custom Authenticator. The framework calls the Authenticator's authenticate method with the request as a parameter. I can get the request body from request.stream.read(). However, that consumes the stream, which prevents the framework from parsing it for me: when the framework calls the view the request has no data attribute as it normally would. request.stream doesn't allow me to seek(0). The request doesn't allow me to replace the stream with a rewound one such as a StringIO. My current workaround is to store the body in request.auth and parse it myself in the view, which works but is ugly. Is there a way to access the request body safely in an Authenticator? -
Django native query v "homemade" sql query to json
The following code works nicely: def jsonLiveLeaderboard(request): data = StraightredFixture.objects.filter(fixturematchday=12) json_data = serializers.serialize('json', data) return HttpResponse(json_data, content_type='application/json') However, if I try to do the same with a homemade query like so: def jsonLiveLeaderboard(request): cursor = connection.cursor() cursor.execute( """ select username as User, floor((count(Goals)/2)-(if(sum(Loss)>0,1,0))) as Round, sum(Win) as Wins, sum(Goals) as Goals, sum(Loss) as Losses from (select u.username as username, s.campaignno as campaign, if(f.hometeamscore>f.awayteamscore,1,0) as Win, if(f.hometeamscore<f.awayteamscore,1,0) as Loss, f.hometeamscore as Goals from straightred_fixture f, straightred_userselection s, auth_user u where s.fixtureid = f.fixtureid and s.teamselectionid = f.hometeamid and s.user_id = u.id union all select u.username as username, s.campaignno as campaign, if(f.awayteamscore>f.hometeamscore,1,0) as Win, if(f.awayteamscore<f.hometeamscore,1,0) as Loss, f.awayteamscore as Goals from straightred_fixture f, straightred_userselection s, auth_user u where s.fixtureid = f.fixtureid and s.teamselectionid = f.awayteamid and s.user_id = u.id) t group by username, campaign having Losses = 0 order by Round DESC, Wins DESC, Goals DESC """) pointsCurrentSeasonLive = cursor.fetchmany(size=8) json_data = serializers.serialize('json', pointsCurrentSeasonLive) return HttpResponse(json_data, content_type='application/json') I get the following error: AttributeError at /jsonLiveLeaderboard/ 'tuple' object has no attribute '_meta' Is there an easy way to convert a "homemade" query to json in much the same way you can with a native Django query?

Django 1.10: Setting admin.site.site_header and using default admin login view
I'm trying to: Use the default admin view (auth.views.login) as my login view Set the admin.site.site_header within ulrs.py so that it appears on the both the login and admin pages First, doing this does update the site_header on the admin page... # urls.py admin.site.site_header = "my header name" urlpatterns = [ url(r'^admin/?', admin.site.urls), url(r'^', include('django.contrib.auth.urls')), ... ] From here it would appear I should be able to either do this: # registration/login.html {% extends "admin/login.html" %} Or this (copy/paste from django/admin/templates/login.html): # registration/login.html {% extends "admin/base_site.html" %} {% load i18n static %} {% block extrastyle %}{{ block.super }}<link rel="stylesheet" type="text/css" href="{% static "admin/css/login.css" %}" /> {{ form.media }} {% endblock %} ... Neither employ the header with "my header name" like the admin view does. Thanks. -
Django. Saving session data for unauthenticated (annonymous) user
Django isn't saving session data from an anonymous (unauthenticated) user. Should this not work? Unauthenticated user goes to URL. Server-side a session variable is set. User clicks on link and another page loads. Server-side it checks for existence of session variable. I expect the previous session variable to be available, but it's not. If the user is authenticated then it works OK. if is_starting_url(): # user does get here the first time. request.session["my_param"] = "1" elif "my_param" in request.session: # user not getting here -
Django Objects of Objects
So, I am trying to pull data into a form. Right now I have a Class set up like this: class Player(models.Model): user = OneToOneField(User, on_delete=models.CASCADE) #some other variables that do stuff and are just static types. I am trying to create a form that enables the updating of data in the "user" variable of my Player class but I can't figure out how to even get to that data. Any help would be greatly appreciated. -
Django server-sent events in 2016
I'm trying to set up a multi user edit session, using server-sent events to warn the user that someone else is also editing that object (like in google docs) class Edit_Session(models.Model): #uuid is a global unique field for all models object_uuid = models.UUIDField(primary_key=True) user = models.OneToOneField(User, on_delete=models.CASCADE) So all I need is to send a message to the client if there is someone else editing the same uuid as him. I've read about websockets, tornado, twisted and all that, but is there a simpler way to achieve this in Django that doesn't involve having to learn another library and figure out how to integrate them with Django? -

How to enable a user to view the django admin home page if nothing but a custom view permission in given to the user?
By adding the following code in one of my models, I was able to add a view permission to the model. class Meta: default_permissions = ('add', 'change', 'delete', 'view') I have created a user in django-admin and given only view permission. I want that the user should be able to only view the values of this particular model. But after logging in with the user I am getting an error that the user dont have the permission to edit anything.(refer screenshot). Is there any way that I can allow the user to view a particular model only by giving the VIEW permission only? Any help would be greatly appreciated. Thanks in advance. -
Django Model Not Updating
I'm trying to count the amount of times a user visits a page: models.py: class Request(models.Model): user = models.ForeignKey(User) view = models.CharField(max_length = 250) visits = models.PositiveIntegerField() views.py def daygaps(request,*a, **kw): request_counter = Request.objects.filter( user__username = request.user.username, view = 'daygaps') if request_counter: request_counter[0].visits += 1 request_counter.update() else: Request.objects.create( user = request.user, visits = 1, view = 'daygaps') When a new user visits the page for the first time, 'visits' gets set to = 1. Each subsequent visit should iterate the count. The "else" block works fine, however "visits" stays at 1 and does not change with each new request a user makes. I've tried the ".save()" method, but that throws an error because "request_counter" is a queryset. -
Django alter model data before rendering ModelForm
I'm trying to generate an object that allows values to be stored in a standard unit, but displayed in different units based on the settings for the project. Below is an example where I need to be able to store the temperature of a room. I want the database value to be in Kelvin for ease of calulations, but want the users to be able to view/enter in F or C as the project requires. The model can take the values from a form and convert them to Kelvin on save. I know this can be done in the form, but I have it here for other data entry methods. A striped down version of the model is as follows: class Room(models.Model): name = models.CharField(max_length=255) temperature = models.FloatField(default=293.15) def save(self, *args, **kwargs): self.temperature = convert.temperature(self.temperature, from_unit=self.plant.temperature_scale) super(Room, self).save(*args, **kwargs) I created a ModelForm to use in CreateView and UpdateView. I needed the ModelForm to limit the queryset for other fields (which works fine). Here I was able to convert the temperature field to the desired units for a new object in CreateView, but I can not seem to find the way to pull this off for an existing record class … -
Django : Extends User model - Application Management
I want to create a projet for online courses, with professors and students. A professor can : Login, logout... Complete his informations (profil page) Accept a course requested by a student A student can : Login, logout... Complete his informations Request a course to a professor It's a good way to doing that like this : Create a first app named 'professors' with professor model (extends User) and views for : complete profil, login, logout A second app named 'students' with students model and views for : complete profile, login, logout A third app named 'courses', with course model, views for professor (accept a course) and views for student (request a course) i want to doing that because in my project, I risk to have big differences between professors and students possibilities...

Django expiring "password reset" model
Let's say my website will have a "reset password" button for when the user forgets his password, it will generate a link with a hash based on url_token field from Password_Reset_Token and email it to the user. If the user access the url, the view can then reset his password and delete the Password_Reset_Token object. But what if it expires and the link isn't accessed? Is there a way to add a daily task to clean expired objects? Or is there a more clever way to do this? Worth nothing that my application is entirely AJAX based and has no url redirecting class Password_Reset_Token(models.Model): url_token = models.AutoField(primary_key = True) created_date = models.DateTimeField(auto_now_add=True) user = models.OneToOneField(User, on_delete=models.CASCADE) expiringdays = models.IntegerField(default = 12)
