How do you add a widget to a form field in init in django?
Basically, I want to change a form field's widget in the init function. First of all, here is the form: class ModelForm(forms.ModelForm): date = forms.ChoiceField() def __init__(self, *args, **kwargs): super(ModelForm, self).__init__(*args, **kwargs) self.fields['date'].choices = DATE_CHOICES class Meta: model = Model fields = ( 'date', ) widgets = {'date': SelectDateWidget()} However, the widget SelectDateWidget() didn't seem to work for some reason. So, I want to instead add this widget to the init function so that the widget would be reflected on the form. However, this is just my thought. If adding this widget to the init function will not work, could you please give me some way to use this widget for the date field? Thank you, and please leave me any questions you have. -

Angular to Django - 'Unknown string format:'
I am building a front end using Angular where the user selects a file and a date (using a date picker). This is then sent to django using the django_rest_framework to to a standalone class that uploads this file onto an oracle database using sqlalchemy.

fork process under uwsgi, django
I need to execute some slow tasks upon receiving a POST request. My server runs under UWSGI which behaves in a weird manner Localhost (python manage.py runserver): when receiving request from browser, I do p = Process(target=workload); p.start(); return redirect(...). Browser immediately follows the redirect, and working process starts in the background. UWSGI (2 workers): Background process starts, but Browser doesn't get redirected. It waits until the child exit. Note, I have added close-on-exec=true (as advised in documentation and in Running a subprocess in uwsgi application) parameter in UWSGI configuration, but that has no visible effect, application waits for child's exit -

Could not resolve URL for hyperlinked relationship using view name "<viewname>". ResourceRelatedField URL/pk problem (django+rest+json api)
Summary Background I am trying to implement a JSON:API-compliant general Django app to be used in various projects. I am able to generate decent JSON:API, but I only get "related"-links for one-to-one relationships (foreignkey in the model). I cannot get "related"-links to reverse relationships (other models with a foreign key pointing to my object). Thank you! //S Questions Is ResourceRelatedField the correct way to implement reverse relationship links (e.g. "related")? How do you properly use ResourceRelatedField with related_link_view_name and _url_kwarg? Specifics There are three models in the database: TopObject, Status and RelatedObject. TopObject-objects has a foreignkey status pointing to Status RelatedObject-objects has a foreignkey topobject pointing to its 'parent' TopObject-object. All of the following url's work properly when entering them manually (e.g. browser or httpie): localhost:8000/topobjects/1/relatedobjects/ (gives a list of related objects with topobject foreignkey = 1) *localhost:8000/topobjects/ (gives list, currently without reverse links. The related link for Status [direct relationship] works). *localhost:8000/topobjects/1/ (gives topobject 1, currently without reverse links. The related link for status [direct relationship] works). localhost:8000/relatedobjects/ localhost:8000/relatedobjects/1/ localhost:8000/statuses localhost:8000/statuses/1/ The view name topobject-relatedobject-list works from views when tested with print(reverse...) When related_link_view_name='topobject-relatedobject-list' is set under ResourceRelatedField, localhost:8000/relatedobjects/ and localhost:8000/relatedobjects/1/ raises a Django error. I have not figured … -
is there a way to display a particular inline in a new page based on a condition?
I need to display only one inline in a new page based on the condition like if the url has the parameter country_id then i need to display only one inline. Since I cannot make it in one ModelAdmin since the model admin has form validations in it, I used two modelAdmins for the same model. I have a readonly field called get_countries in CorporateConfig(admin which has form validations) and it will display a list of countries.
