How to update progress bar while making a Django Rest api request?
My django rest app accepts request to scrape multiple pages for prices & compare them (which takes time ~5 seconds) then returns a list of the prices from each page as a json object. I want to update the user with the current operation, for example if I scrape 3 pages I want to update the interface like this : Searching 1/3 Searching 2/3 Searching 3/3 How can I do this? I am using Angular 2 for my front end but this shouldn't make a big difference as it's a backend issue. -

get_absolute_url with multiple foreign key
Hello Django Pros out there! Is it possible to get the pk of a model, which is not the direct foreign key of the model? But the foreignkey of the foreign key model?

It should redirect to the Patient detail page. Due to this it needs the pk of the Patient class. My try: def get_absolute_url(self): return reverse('member:detail', kwargs={'pk': self.examination__patient_id}) The error says that there is no URL to redirect to.

Upload a relatively big excel in Django and improve the write speed (Postgresql)
I am uploading a 4000 row excel in Django (I'm using django-excel as an external plugin), which is taking around 17 seconds. This sounds very low in comparison to a normal POSTGRESQL write qps (queries per second) expected to be about 600-700.To maintain data integrity and to add a specific column, I need to do entry of one row at a time.

django models/admin issue - admin displays table twice
We moved a django model from one app to another ("PollRunForJira" was moved from "reports" to "jira_fat"). All the code seems clean from the old model and the django_migrations DB table is clean from the old model too. Still the django admin display the 2 models: The new model is functional (we can drill into it in the admin", while the old one appears but we cannot drill into it. How is it possible to get rid of the old model display in the admin? Where does Django gets the information from if it doesn't appear in the code/DB. Thanks -

Revelants queries suggestion for autocomplete with Solr
I use Solr 6.4 with Haystack 2.6.1, pySolr 3.6: I'm looking for a google like suggestions autocomplete. Actually use EdgeNGram works good but it returns my documents titles only what is not what I want: example: typing: 'new y' return: New york, fabulous city that never sleep A trip to new york by night ... This give the user only the choice to select a document in particular in the suggestion list and the search will return only document with search based on suggested title. What I want is a suggestion of revelants words like: typing: 'new y' return: new york new york by night new york city trip to new york There is an article that suggest to use indexed queries by users that return results and then to use these queries as suggestions: https://lucidworks.com/2009/09/08/auto-suggest-from-popular-queries-using-edgengrams/ This mean parsing solr log or use a Data import (DIH) from a bunch of saved user's queries in DB.

updating a django model after saving it
I have a model like this: class Thing(models.Model): photo = models.ImageField(...) verified = models.NullBooleanField(default=None) Using django-rest-framework, I upload an image over an API, which I then need to run some checks on (postprocess it). I need Thing.photo to be saved so that I can run the checks. The checks need to happen within the request cycle, as the HTTP response depends on the outcome. I am using a post_save signal for this now, in which I check the created argument to avoid recursion (as explained in Django signal post_save update) and run the checks only the first time the object is saved. This works, but I am hitting the database twice, which seems unecessary. Ideally I would do something like: def save(self, *args, **kwargs): self.photo = store_the_uploaded_blob() self.verified = run_checks(self.photo) super(Thing, self).save(*args, **kwargs) Can I do this? And how? -
"django.conf.urls" is invalid syntax? Newbie here
I'm trying to create a website in python using Django, and while i was trying to point the root URLconf at the polls.url module. I am following the tutorial here: https://docs.djangoproject.com/en/1.10/intro/tutorial01/ When O test it using python manage.py runserver, the command prompt says django.conf.urls` is invalid syntax Pointing at the "o" in django to be precise. Code I'm using is the same as in the tutorial, this is what it is: from django.conf.urls import include, url from django.contrib import admin urlpatterns = [ url(r'^polls/', include('polls.urls')), url(r'^admin/', admin.site.urls), ] And I put it in mysite/urls.py. I'm a complete newbie, so I hope this doesn't sound like an incredibly dumb question. My Django version 1.10.6, Python is 2.7.12. -

Django How to get event of user choosing a file?

Exclude field from GROUP BY in Django ORM
We have a system written in Django to track patients recruited to clinical trials. Spread sheets are used to record the number of patients recruited each month throughout a financial year; so the sheet only contains 12 months of data even though a study may run for years. There is a table in a django database in to which the spread sheets are imported each month. The data includes the month/year, a count of patients, and some other fields. Each import will include all the previous months data; we need this to make sure no data has been changed on the import sheet since the last import. For example, the import table containing two imports (the first up to January and the second up to February) would look like this: id | study_id | data_date | patient_count | [other fields] --> 100 5456 2016-04-01 10 ... 101 5456 2016-05-01 8 ... 102 5456 2016-06-01 5 ... ... all months in between ... 109 5456 2016-01-01 12 ... 110 5456 2016-02-01 NULL ... 111 5456 2016-03-01 NULL ... 112 5456 2016-04-01 10 ... 113 5456 2016-05-01 8 ... 114 5456 2016-06-01 5 ... ... all months in between ... 121 5456 … -

Create a full-duplex communication between heterogeneous WebApps for long-polling (Django and other)
We have a microservices architecture with a chain of micro-services polling one with the other. All our webservices are written in Python, but using different frameworks The polling chain would be: Browser(JS) --polls N-status--> WS1(Django) --polls M-status--> WS2(Custom Python) --polls P-status--> WS3(Django) Between each web-services there is a polling of different status. We are looking at Django Channels, but it seems applicable to a communication between two Django web-services, even if it uses WebSockets. How can we have a standard, consistent way to create long-term full-duplex connections between heterogeneous web-services. So that a Producer dispatch changes, and Receivers can handle them. Seems that Websockets are use mainly for Browser->Server communications. What would be the way to go? -
Django Admin Fk grouping
How do I go about grouping a set of fields within the Django Admin. By this I mean Table 1: User - User Key - User Name Table 2: Post - Post Key - User Key (FK) In the PostAdmin I would like to display the User Name of the Author also perform an action on the blogs. This works but displays the user name for each blog created by the user. Is there a way I could just display the user name once but in the action update all blogs created by the user?

Adding objects to ManyToMany field
I have a model called 'Line', which has a ManyToMany relationship with 'User'. What I am trying to do is to render the form of the line excluding the User field in order to create a costum rendering for the ManyToMany field where the user can search within all the users and then he checks the checkboxes beside the users' names. Then I read the ids of the selected users and get the users from the database and try to set the users of the new line object. Here is the code: Model: class Line(models.Model): name = models.CharField("Name", max_length=50) owners = models.ManyToManyField(User, related_name="owners") def set_owners(self, users): self.owners.clear() for user in users: self.owners.add(user) self.save() Forms: class LineCreationForm(forms.ModelForm): class Meta: model = Line exclude = 'owners' def __init__(self, *args, **kwargs): super(LineCreationForm, self).__init__(*args, **kwargs) for filed in self.visible_fields(): filed.field.widget.attrs['class'] = 'form-control' Views: def new_line(request): if request.method == POST: form = LineCreationForm(request.POST) if form.is_valid(): line = form.save() if 'line_owner' in request.POST: get_integers_from_checked_checkboxes(request, 'line_owner') selected_users = User.objects.filter(pk__in=owners_ids) line.set_owners(selected_users) return redirect(home_page) The problem: I tested the users list and it is working fine. The problem is the owners list stays None after calling the 'line.set_owners(selected_users)' function.
