Switching between currencies and displaying the corresponding price in Django template
There is Product model with price field in my Django app. Base currency is USD. There are couple of Product instances rendering in the template at the same time. I would like to add ability to switch between different currencies and render a corresponding price in template, but i don't know how. I've read Django-money app documentation and tried to implement currency exchange using FixerBackend and fixer free account. But i failed. Could you please share some experience from your projects and give some tips which way to implement this idea is the easiest and best, cause i'm stack.. -
Django: Update an object form form
I'm trying to make my view to update an existing object, filling its attrs with form data. I found the syntaxis for this: Auxi.objects.filter(id=auxi).update(name='The new name', age=23, role='The new role') But the problem is that it will become too extensive for my object since it has 52 attrs and I just want to tell Django to replace all the values from my object with the data from form. I tried: form = AuxiForm(request.POST) item = form.save(commit=False) Auxi.objects.filter(id=auxi).update(form) and also Auxi.objects.filter(id=auxi).update(item) But it's saying update() takes 1 positional argument but 2 were given. Could someone help me please? Sorry if it's a duplicate post, I already tried to find it somewhere but I couldn't. -
How to access tables from a different schema in oracle 11g using django?
I have a user named mi_abc in oracle 11g. The user do not have any table in the database but has access to all the tables in another schema sch_abc. When I run a normal select query from sqldeveloper on the sch_abc schema from mi_abc, it works perfectly fine, but when I use django, I am always getting the error:- django.db.utils.DatabaseError: ORA-00942: table or view does not exist I tried to set the db_table = sch_abc.tableName and also set db_table = tableName but both gives me the same error. Any clue how to resolve this? -

Django - create multiple elements of different model at once
I have 2 models with OneToOne relation between them.

Unable to bind event to datetimepicker in javascript
I'm running django-bootstrap-datepicker-plus==3.0.5. I'm attempting to bind an event to the datetimepicker so that that on a certain action, an attribute changes. The list of attributes that can be changed are found here: https://eonasdan.github.io/bootstrap-datetimepicker/ As the page above shows, I should just be able to use the following code to set inline to true (note: I'm able to set this attribute to true on the initialization of the form in forms.py and it works fine). $(document).ready(function() { $('#datetimepicker').datetimepicker({ inline: true, }); }); Unfortunately, this code doesn't do anything. Should I be using '.datetimepicker' in the code above? Is there anything different about the django version of this datetimepicker that is causing this code not to work? Not sure if this makes a difference, but the following code does work: $('.input-group').on("dp.change", function(e){ console.log('There was a change to the date'); }); Thanks for the help! -

How to filter objects by slug instead id

Django ModelFormSet object changes type on post
I'm converting a page from using manually rendered post/get functions to one using class-based views. I am attempting to move towards using all of Django's built-in functionality.

How do I configure multiple django applications to use the same database?
As I configure my Django applications to use containers I'm left with a problem as I try to separate my processes into smaller images. How can I break logic into smaller components that run in their own containers, yet access the same database? I realize that in a "true" microservices environment I'd want a different database for each service. However, consider a situation where I have a bit of logic that reads data from a database, and produces a CSV file. I'd like to break out that into a separate type of image, that contains only that logic and gets a special disk mount to write the file to. The rest of the applications remain stateless. So I'm left with needed two django applications, one that reads and writes data to its database, and another one that I can use to spin up and run reports against that same database. Option 1: Is that I keep using the same application, where the models have already been defined. I spin up one container for processing, and spin up another container of the same image for use for reporting. While this would work, it seems like it would be a better pattern … -
Django Blog Post Text Editor Deleting Leading Spaces
This seems to be a problem on all Django blog frameworks that I've come across, and I am currently experiencing it on Mezzanine's "Moderna" theme. When making a blog, in the contents section, if one pastes any text, it automatically loses leading spaces/tabs on each line. One cannot indent lines with the tab key either. Is there any way to keep the leading spaces in the text editor when pasting formatted text? -
Serialize foreign key's foreign key (DRF)

Django double post request after a Heroku application error
I was wondering if there is a way to prevent a double post request after an application error happens. I run a Django app on Heroku and sometimes when I hit a submit button, an application error occurs. I can't figure out why this happens, but that's another question ;-) When I refresh the application error page, I get redirected correctly, but the post request was done twice. Is there a way to prevent this double post? -

How to fix 'ImportError' while working with multiple Django apps

Error related to parser.add_argument() when writing a custom django-admin command
I am writing a custom django-admin command which is the module named populate_db.py. Its location is the following within the django project: restaurant/ __init__.py models.py management/ commands/ _private.py populate_db.py tests.py views.py formDict.py The purpose of populate_db.py is to add objects to DB tables from an external dictionary {'key1':[values], 'key2': [values]}. The formDict.py forms a dictionary (d), and prints json.dumps(d) to stdout. Therefore, the dictionary is serialized to a JSON formatted string with double quotes and printed to stdout. When I run python restaurant/formDict.py while being in the directory where manage.py is located, the program is successfully completed and the JSON formatted string (converted dict) is printed to stdout. When I run the command python resturant/formDict.py | python manage.py populate_db while being in the directory where manage.py is located, I immediately get the following error: AttributeError: 'NoneType' object has no attribute 'items' Here's some parts of populate_db.py.

In Django, how do you reference your project urls.py URLs?
I am making a django project with multiple apps inside of it. My directory structure is something like this: DjangoProject project_dir settings.py urls.py wsgi.py app1 urls.py ... app2 urls.py ... I understand how to access urls in my templates that are part of apps with {% url 'app1:url1' %} but that is because in my app urls.py files I can do something like this: app_name = 'app1' urlpatterns = [ path('', views.view1, name='home'), ] The project urls.py file seems to be different than app urls though. You cant give the project urls.py file an app_name so how is one supposed to reference project urls from inside a template? I have been just relying on relative links like this: <a href="/global_url"></a> but if I ever want to change the path of /global_url I have to go and update all my hard coded template urls. -
How to use Django FilterSet to filter MultiSelectField?
I've created a FilterSet using django_filters so users can filter through other user's profiles using filters such as city, age and gender. Those 3 fields in the FilterSet work fine, however I also want to filter by interest which is a MultiSelectField based on INTEREST_CHOICES. A user should be able to check multiple interests and filter based on those, in addition to the 3 fields listed above. I have been unable to get this to work. I managed to display an interest filter field however when a user selects one of the 4 interests from the dropdown box, the page does not return any matches, even if one of those interests is matched. I suspect it is because users select more than one interest, thus the interests are saved in a list and not individually, therefore the FilterSet can't find the standalone interest. If someone could look over my code and point me in the right direction, I would be most grateful. models.py class Profile(models.Model): INTEREST_CHOICES = ( ('FITNESS', 'Fitness'), ('CHURCH', 'Church'), ('VEGANISM', 'Veganism'), ('MOVIES', 'Movies'), ) GENDER_CHOICES = ( ('M', 'Male'), ('F', 'Female'), ('X', 'Neither') ) user = models.OneToOneField(User, on_delete=models.CASCADE) interests = MultiSelectField(choices = INTEREST_CHOICES) city = models.CharField(max_length=30) age …
