action methods is not allowed to have more methods rather than their viewsets

[Ali Yazdi]

1. I have a `viewsets.ModelViewSet` that has `http_method_names = ['get']`

2. and its action method needs to have `methods=['get', 'post']` 

3. But `post` method is not allowed for its action

4. I don't is it normal behavior to have this scenario or not?

If you set `http_method_names = ['get']` and the POST is on the same endpoint it won't allow a POST. You might want to add 'post' to that variable.

I, myself don't use ViewSets. I tend to use generic Views. In your case the ListCreateAPIView generic view in this case. You can find it at https://www.django-rest-framework.org/api-guide/generic-views/#listcreateapiview

Thanks for your answer. I try using `(mixins.RetrieveModelMixin,mixins.ListModelMixin, GenericViewSet)` without setting `http_method_names = ['get']` and my action works fine for `post` method.

Thank you Carl.

I've got a new problem with this new viewset that when I generate schema with `generateschema --file schema.yml` it says:

```

 UserWarning: <class 'recommendation.api.views.RecommendationViewSet'> is not compatible with schema generation

  warnings.warn(

```

But, it creates the schema of that viewset!

[Carl Nobile]

As I said I don't use ViewSets, but if you add in mixins that cause the signature of the ViewSet to change it cannot easily and automatically generate schemas--at least this is my understanding.

The mixins are used in generic views and are not generally needed when defining your own views except under very few situations when you need to override a lot of functionality in the given generic views.

You might want to just use the generic view I mentioned previously.

ViewSets are there to make things easy and give you some additional perks, but they take away a lot of flexibility.
