No OCR tool found in python
I have downloaded Mayan EDMS-Electronic Document Management System from GitHub and I configured project using Django server. I had added the required libraries based on requirement. Now the project runs with error ocr.exceptions.OCRError: No OCR tool found When I searched this error, I found Pyocr looks for the OCR tools (Tesseract, Cuneiform, etc) installed on your system and just tells you what it has found.

How to reorder dropdowns in django-admin inlines?
I'm trying to give some order to our django admin dashboard. At the moment I am able to order dropdowns by the field name using this code in MyModelAdmin: def formfield_for_foreignkey(self, db_field, request, **kwargs): if db_field.name == "program": kwargs["queryset"] = models.ProgramModel.objects.all().order_by('name') return super(MyModelAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs) So, when I go to the MyModel I see the dropdown alphabetically ordered like in this image: The problem is that if I bring that model as an Inline in a different model, it is not ordered anymore: How can I have that dropdown ordered also in the inline element?? I already tried adding ordering to my MyModel meta class and it works, but I would like this to affect only the admin page and to be completely decoupled from the model. -
customising django auth.view or custom login view
in my Django app i need to provide rest api's for almost all the views. so what i need to do is provide login option by using an api. The default behaviour of auth_views.login is to redirect after login to a redirect url specified, however i need to check if content-type is application/json in the request i need to return the session id instead of redirecting to the redirect url & then the user can use this session id to use other api's? how could i do that. remember i cannot usedjango-rest-framework -
Django - PostgreSQL set statement_timeout
I'm using Django 1.10 and PostgreSQL DB. I'm trying to figure out whether I can set statement_timeout from Django. Seems like I can't do it the same way as for connect_timeout (in settings.py): DATABASES[DEFAULT]['OPTIONS'] = { 'connect_timeout': float(os.getenv('DEFAULT_DB_OPTIONS_TIMEOUT', 5)) } I saw something like this, but I can't find a way to verify it actually works: DATABASES[DEFAULT]['OPTIONS'] = { 'options': '-d statements_timeout=700' } I know I can set it directly from the DB like: set statement_timeout=5000 but I'm looking for a way to do it from Django. -
How to serialize nested model in Django-Rest

Rendering PagedownWidget in a formset
I'm unable to render the pagedown widget (widget that contains buttons for bold, italics, etc) in forms that are rendered as part of a formset. My model and form are as follows: models.py class Services(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, default=None) body = models.TextField(max_length=5000, null=True, blank=True) def __str__(self): return self.user.username forms.py class ServicesForm (forms.ModelForm): body = forms.CharField(widget=PagedownWidget(show_preview=False)) class Meta: model = Services exclude = ('user',) I've included the following template tags in the template in order to render the form. {% block head_extra %} {{ form.media }} {% endblock head_extra %} Essentially, I've gotten this code to work on a regular form, but it doesn't seem to work on a formset. Any thoughts? Do I have to manually render the widget with a template tag? Thanks! -

Django Rest Framework: How to get errors in a list when creating multiple records
I am trying to create a serializer to create multiple products with one payload.

For example, product A is created, but product B returns an error. [ { "id" : 1, "sku" : "12345", "product_name" : "Product A" }, { "error" : "Unable to create product" } ] How can … -

But with slash at the end is working fine. Is there any option to make this url without with slash at the end ? Especially for the post urls -
Checking tree modifications in django-treebeard ORM before saving
I want to double-check if I am correctly interpreting the following section of the django-treebeard docs: django-treebeard uses Django raw SQL queries for some write operations, and raw queries don’t update the objects in the ORM since it’s being bypassed. Because of this, if you have a node in memory and plan to use it after a tree modification (adding/removing/moving nodes), you need to reload it. Here's my understanding: If I've loaded a node from the database and am working on it in memory, I must use refresh_from_db() before saving. Also, in case the tree is modified between refresh_from_db and save, I should wrap the two calls in an atomic transaction. Is this correct?
