Fragments not working #1
Description
First of all: thank you for contributing this! Django is great, GraphQL is great, but Relay was too much for me.
I noticed that queries with fragments are not yet supported. For instance:
query Objects {
object {
results(offset: 0, limit: 20) {
...ObjectFragment
}
totalCount
}
}
fragment ObjectFragment on ObjectType {
id
__typename
}I have worked around the issue by changing utils.py on line 105, since it looks like that method only optimizes the query:
...
elif hasattr(field, 'selection_set') and field.selection_set:
...I found something that might help here. See the get_fields method.
Here is a traceback:
