Swagger UI examples using drf-spectacular and x-www-form-urlencoded requests
Is it possible to generate a swagger UI page (and redoc for that matter) that has examples for both application/json and x-www-form-urlencoded request bodies? I can get examples for application/json, but not when selecting x-www-form-urlencoded as the request type fro the swagger/redoc UIs. I'm using the following decorator for the "create" method (in a ModelViewSet) @extend_schema(request=MySerializer) where MySerializer looks like the following... @extend_schema_serializer( examples=[ OpenApiExample( 'Example input', description='Creation of an alias', value={ 'user_id': 1234567890, 'obj_id': 288, 'alias': 'my alias' }, request_only=True, response_only=False, ), ], ) class MySerializer(serializers.Serializer): user_id = serializers.IntegerField() obj_id = serializers.IntegerField() alias = serializers.CharField(max_length=50) The swagger/redocs UIs will happily provide an example dropbox with "Example Input" for an application/json request body (whereby selecting the example will populate the json), but for x-www-form-urlencoded will just show a form to fill in, with no example dropbox in order to populate the fields. I can get examples (and their selection drop boxes) for query strings, i.e. when making GET endpoints that use OpenApiParameter e.g. @extend_schema( parameters=[ OpenApiParameter(name='q', description='Query string to search for', required=True, type=str, examples=[ OpenApiExample( 'Search query', value='foobar' ), ] ), ... ] ) where selecting a drop box entry will populate the text field. However, for x-www-form-urlencoded, this doesn't … -
How can I get libdbcapi_r.so, libdbcapi_r.dylib needed for sqlany-django?
I installed and configured sqlany-django, but have error Could not load dbcapi: Tried: dbcapi.dll, libdbcapi_r.so, libdbcapi_r.dylib. I installed sqlany-django with pip install sqlany-django. According to this I should run $ . /opt/sqlanywhere16/bin64/sa_config.sh , but I don't have a script sa_config.sh.

How can I solve this? my system is Ubuntu 18.04 Django==1.9 sqlany-django==1.13 sqlanydb==1.0.11 -
Django: Loop through all attributes of a OneToOneField inside the template
I am trying to loop through all the related attributes of a OneToOneField inside a Django template but it gives an 'PropertyFeatures' object is not iterable error. This list of features is going to grow considerably and rendering them out individually with their own {% if %} statement is not a good idea. Is it possible to loop through OneToOneField attributes inside the template? Models class PropertyFeatures(models.Model): property = models.OneToOneField(Property, related_name="features", on_delete=models.CASCADE) is_pet_friendly = models.BooleanField(default=False) has_garden = models.BooleanField(default=False) Views def property_detailview(request, pk): template_name = "property/detail.html" property = Property.objects.get(id=pk) context = { "property": property, } return render(request, template_name, context) Template {% block content %} {% include "includes/navigation/navbar.html" %} <div class="container"> <h1> {{ property.title }} </h1> <div> {{ property.features.has_garden }} <-- This works {% for feature in property.features %} <-- This gives an error {{ feature }} {% endfor %} </div> </div> {% endblock content %} -

django access model attribute by subscription
I have a Profile schema: class Profile(models.Model): likedArticle = models.ManyToManyField('articles.Article', related_name='liked_article_set', blank=True) staredArticle = models.ManyToManyField('articles.Article', related_name='stared_article_set', blank=True) likedQuestion = models.ManyToManyField('questions.Question', related_name='liked_question_set', blank=True) staredQuestion = models.ManyToManyField('questions.Question', related_name='stared_question_set', blank=True) there are tons of other like-able and star-able object (only two examples Article and Question provided above), which follows the naming convention of liked<Model._meta.app_label>. I am coding a method for like and dislike serialisation: def tree(model, user): return { 'liked': model in user.profile.likedArticle.all(), 'stared': model in user.profile.staredArticle.all(), } The method is much more than the minimal example provided above, which if I write profile.likedModel, I need to define a method in each Model class, this is tremendous and not pythonic. therefore, I seek for a way, to automate the queryset. here are some methods that I am aware: model.__class__ # Model Model._meta.object_name # return Model in type of str First, I tried subscription: user.profile[f'liked{model.__class__._meta.object_name}'].all() # TypeError: 'Profile' object is not subscriptable Then I tried __dict__ method: model.__dict__ # returns attributes, except for callable, and many to many manager not included in the result Besides going with eval or exec, is there any other ways? thanks for your help. -
