Graphene-django: cookbook example doesn't work?

[zamesilyasa]

I am trying to run cookbook example and when I try to get item by ID, web client raises an error:

query {
ingredient(id: "SW5ncmVkaWVudE5vZGU6MQ==") { # actual id is takef rom the previous request
name
}
}

I followed the docs on Cookbook as well and it seems that those are not updated for the newest django-filter updates. Any idea what would be changing for the new filtering release?

Thanks!

I also followed the docs to build the cookbook example.

An error occurred, so I checked the issues and ended here. After that I tried @jtaylor32's graphene-tutorial repository that looks very similar to my code. The same error occurs.

The last lines of the traceback File "/Users/rm/.virtualenvs/graphene-tutorial/lib/python3.5/site-packages/django_filters/filterset.py", line 375, in get_ordering_filter "'order_by' is not compatible with the 'fields' dict syntax. Use OrderingFilter instead." AssertionError: 'order_by' is not compatible with the 'fields' dict syntax. Use OrderingFilter instead.. led me to django-filter.

django-filter==0.15.0 made a lot of related changes to OrderingFilter.

There is also a migration guide.

I hope the provided information helps to find out the problem.

if you're only using this for trying out and not for production, you can comment out django-filters assertion check on site-packages/django_filters/filterset.py line 374-375:

@classmethod def get_ordering_filter(cls, opts, filters): # assert not isinstance(opts.fields, dict), \ # "'order_by' is not compatible with the 'fields' dict syntax. Use OrderingFilter instead."

that will resolve the assertionerror issue and graphql cookbook will work fine

@zamesilyasa were you able find a solution for this? running into same issue here.

[zamesilyasa]

Not yet.

[chriscauley]

@zamesilyasa @nsuthar0914 I fixed it in PR #43. Briefly, graphene imports a lot of things to the root library so you can just do graphene.Blah and graphene.Foo. However, graphene.Field is not the same as graphene.Node.Field. I don't know what the difference is, I just (luckily) noticed this working through another example. After changing x = Field(XNode) to x = Node.Field(XNode) for category and ingredients I got the below screenshot. Cheers!

[lebeier]

@chriscauley, hi can u show what are the files that u have changed from graphene.Field to graphene.Node.Field? Apparently, I don't see any graphene.Field anywhere in the example code for cookbook.
