Django: How to create a new model with a foreign key associated to a previously visited model
I'm currently working on a web app, and I'm using config files to load up the names for certain models. How would I go about associating these created models to a foreign key associated to a parent model class that already exists in a different app. For example, I have the following models #Base models.py class Parent(models.Model): name = models.CharField() #Child models.py class child(models.Model): name = models.CharField() Parent = models.foreignKey('Parent', on_delete = models.CASCADE) The first base models will already exist within the database and will be used in a previous view. Then in the current views I'll call a function that will get or create a certain amount of child models, based on the number of rows in the csv file, and pass these generated models into the html template. What I'm not sure how to do is making sure that the models created in the function will have the appropriate foreign key that associates it to the right specific model used in the previous view. I'm still pretty new to Django so any help is appreciated. -
How to use correct oAuth2 redirect url in Django test case?
My Django webapp uses oAuth2 to get authenticated in Strava. I have a link in my webpage that sends a request to Strava indicating a redirect url amongst other arguments. In this example case http://127.0.0.1:8000/token_exchange Strava then makes a request to that url with the code to exchange for the access token. I have a view that does that exchange in that url. Everything works fine. My problem is that I am trying to build an automated test. But when I launch the tests (with python manage.py test) the server does not run in port 8000 but in a different port. Is there a best practice way to manage that redirect url so that it has production domain in production but uses the test server address when running the tests? Thanks!!! -
Getting Django ORM data to Javascript for evaluation
I have a ORM call that returns values from a database. I pass that to the HTML template, but need that data for a Javascript call. So the process is this: Form loads and calls ORM, gets values from Database (lets call it db_data) db_data is passed to HTML template return render(request, "foo.html", db_data) User in the UI clicks a button in foo.html On button click, JS function set_ui_data() is called set_ui_data() evaluates user selection and presents db_data to UI What is the proper way to give the data from db_data to a set_ui_data() method for evaluation? -
Django validate form with RangeWidget
I have a form: class MyForm(forms.ModelForm): class Meta: model = MyModel fields = ['name', 'description', 'slot',] widgets = { 'slot': RangeWidget(forms.DateTimeInput()), } I am receiving the form in the view: if request.POST: form = MyForm(data=request.POST) if form.is_valid(): But the form is never validated as the parameters posted are: name: 'TEST', description : 'fsd', slot_0: '2018/05/15 21:00:00', slot_1: '2018/05/15 21:30:00', submit: 'submit' The form.errors are: Enter a valid date/time. I assumed django would automatically create a tuple of datetime objects for the values posted, but apparently not. How can I validate this form and save it to the database? -
Django - Tutorial - Setting IndexView but Getting TemplateDoesNotExist
I have searched through all the questions here already on TemplateDoesNotExist. I have also been troubleshooting this for about 12 hours. There is something I am not understanding. I am new to django. I am following the following Thinkster tutorial: Building Web Applications with Django and AngularJS Here is the error: Template-loader postmortem Django tried loading these templates, in this order: Using engine django: django.template.loaders.app_directories.Loader: C:\Users\Workstation333\AppData\Local\Programs\Python\Python36\lib\site-packages\django\contrib\admin\templates\index.html (Source does not exist) django.template.loaders.app_directories.Loader: C:\Users\Workstation333\AppData\Local\Programs\Python\Python36\lib\site-packages\django\contrib\auth\templates\index.html (Source does not exist) django.template.loaders.app_directories.Loader: C:\Users\Workstation333\AppData\Local\Programs\Python\Python36\lib\site-packages\rest_framework\templates\index.html (Source does not exist) This is the code I do not understand, and I believe is where the problem lies.

Using collections.Counter() with a Django queryset that has negative integers
As a follow-on to this question which was resolved using Counter(), I've run into a new problem that seems easy enough to fix - except I can't get it to work. I'm trying to use Counter() to sum a series of dict entries which works if the sum is a positive integer, BUT returns an empty element if the sum is a negative integer. I was able to find this answer which is right on point in explaining that Counter() is designed to count and not sum, per se. I can recreate the example and get it to work, but with a django queryset, when coupled with the Counter() method, generates a more complex dictionary that looks like this. totals = { 'sumthing_a': Counter({'total': 48000}), 'sumthing_b': Counter({'total': 39050}), 'sumthing_c': Counter({'total': 8950}), 'sumthing_d': Counter({'total': 10000}), 'sumthing_e': Counter({'total': 17200}), 'sumthing_f': Counter({'total': 17750}), 'sumthing_g': Counter({'total': 30450} } I've tried variations of: totals.update('sumthing_e: Counter({'total': 300})) which replaces the original 17200 with 300 rather than adding them. I've also tried: totals['sumthing_e'].update('sumthing_e: Counter({'total': 300})) which throws: unsupported operand type(s) for +: 'Counter' and 'int' The documentation for .update() states: Elements are counted from an iterable or added-in from another mapping (or counter). Like dict.update() but adds … -
Get Model-object from view?
My views.py file has many functions that eventually call a HttpResponse. They render a template, individually, that is report, with a chart This report, previously has to be added in the /admin. This makes the Report object, which has many fields, but I only need the one called 'codename', that was given in the /admin. How do i get the current Report-object related to the view?

Getting type error while trying to authenticate user

Django: creating child objects within post_save
I have a site that updates data from a call to an API. So, in order to poll the API for the relevant fields, I have an "ingest_on_save" flag on the model, that's checked in a @pre_save handler, and after grabbing the API data will create or update the record. At the end of the @pre_save it turns the ingest_on_save to False and proceeds with save(). It works great! BUT the API also has pointers to child objects that are in a different model (e.g., a Book models with a FK to Author). If I change my Author model to also have a "ingest_books" flag, I can create/edit Books from it's @pre_save similarly (from the Author @post_save - necessary because I need the PK if the Author is newly-created to set the FK between Author and Book), but I can't figure out how to unset the Author.ingest_books since save() has already been called (and calling it from it's @post_save creates an infinite recursion loop). I've seen answers for other similar situations saying to use queryset.filter(pk=instance.pk).update except that there's no queryset that's reachable from @post_save (and those answers don't say how they were able to reach it)... ... ideas? -
In Django, for a OneToOne relationship between two objects of the same class, can an object be prevented from referring to itself at the db level?
I have the following in my app: class University(models.Model): ... sister_university = models.OneToOneField('self', related_name = 'university_sister_university', blank=True, null=True, on_delete=models.SET_NULL) As it is, under the Django Admin site, I’m able to select University A as the sister_university of University A (itself). Is it possible to enforce some sort of a rule at the database level so a university object can never be its own sister_university? Alternatively, is there a better way of accomplishing what I’m trying to do? -
Duplicate Title Tags with Django Pagination
I've recently deployed my website infortion. On the home page, I've used the django pagination so that users can see more content. Few days ago I connected the site to webmasters & it's showing an error Duplicate title tags in the HTML improvements section. Problem is coming from the home page because pagination is taking the users to next page but still keeping the same title. Which means these two pages, / /?page=2 will have the same title. How can we solve this problem? Thank You. -
Use Django signal when data is inserted into database from Scrapy
I would like to integrate Scrapy with Django. When I insert data into DB from Scrapy, Django signal is not working. This is the code snippet that is used for signal. @receiver(post_save, sender=Page) def create_page(sender, instance=None, created=False, **kwargs): if created: print('========== page created') This is pipeline.py that is used to insert data into DB. class CrawlerPipeline(object): def __init__(self, unique_id, *args, **kwargs): self.unique_id = unique_id @classmethod def from_crawler(cls, crawler): return cls( unique_id=crawler.settings.get('unique_id'), ) def close_spider(self, spider): pass def process_item(self, item, spider): site = Site.objects.get(id=self.unique_id) page = Page(url=item['url'], site=site) page.save() return item As you can see, data is inserted into DB on the Scrapy part and it works. But Django signal is not working as I expected. I am not sure how I can get Django signal to work. -

Django: Form for each entry of a model
I am trying to implement a form to edit a field 'comments' for each entry of a given model, which is in my case 'Rental'. class Rental(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) object = models.ForeignKey(Inventory, on_delete=models.CASCADE) quantity = models.IntegerField() returned = models.BooleanField(default = False) due_date = models.DateField() issue_date = models.DateField(default = datetime.date.today) comments = models.TextField(max_length = 500, null = True, blank = True) def __str__(self): return self.user.first_name + " - " + self.object.name I don't take input for comments when making a new record but the user should have an option to give a comment afterwards. I need to make multiple forms and user should be able to write a comment and submit it using a button exactly next to the box. I tried using formset and inlineformset but they don't do what I need. Is there any other way to solve this problem. Thank you in advance. -
how to get posted object in django rest framwork from a request

Getting Django error 'AnonymousUser' object is not iterable after redirecting back from Stripe page
So it is my understanding that this error comes about from trying to call request.user when a user isn't logged in. The problem I'm having is, I am using Stripe Connect Express so I can have users sign up with debit card or bank account for payouts in my marketplace app. This redirects the user to stripe for a few pages. When Stripe collects the data it needs it redirects the user back to my page where I use request.user to pull their info from the database so I can save Stripe data to their table. I'd say about 50% of the time this is successful and the other half I get the error TypeError at /pricing/ 'AnonymousUser' object is not iterable This leads me to believe that the user is logged out sometime during the redirect to Stripe. Is there a solution to this issue? Is my session expired? Did the CSRF token change? Also, Stripe allows you to pass a 'state' query parameter in the POST request to them which they suggest to is for matters like CSRF tokens. They then return this 'state' to you in the redirect GET request they send from their servers. Can I … -
Can't see my project's strings in Django Rosetta

Python Django URL Match Issues with Anchor Tag
I have a question regarding why Django isn't matching my the url in an anchor tag in my template. I'm finding that in this one instance, if I put a button inside an anchor tag, Django won't match it because it looks for a trailing slash. If I put the button inside a form, it matches fine. <a href="/reset"><button>Reset my account</button></a> The above code returns a 404 error: Using the URLconf defined in main.urls, Django tried these URL patterns, in this order: ^admin/ ^ ^$ ^ ^process$ ^ ^checkout$ ^ ^reset$ The current URL, reset/, didn't match any of these. If I put the button inside form tags, it works fine: <form action="/reset"> <input type="submit" value="Reset my account"> </form> Alternately, if I add a trailing slash to the path in my_app/urls.py, the anchor tag will work: url(r'^reset/$', views.reset) Why is Django trying to match a trailing slash in this instance? I have used this approach before without issue. Thanks! -

jQuery + django sending ordered list of numbers
I have a simple task list that the user can choose how to order. When the user order the tasks I want to send all the tasks' IDs in their order to the server. In short, what is the most convenient to send a javascript array and fetch the values in django view? If I do this: // tasks is an array of numbers, e.g [1,2,3,4] $.post('/save_tasks/', {tasks: tasks}).done(...) then I can access them in the view with request.POST.getlist('tasks[]') But this does not guarantee the order.
