It's worth noting that the the "view function" of GraphQLView is contained in GraphQLView.__call__. So, when you create an instance, that instance is callable with the request object as the sole positional argument. To illustrate:
gql_view=GraphQLView(schema=Schema, **kwargs)
gql_view(request) # <-- the instance is callable and expects a `aiohttp.web.Request` object.
Supported options for GraphQLView
schema: The GraphQLSchema object that you want the view to execute when it gets a valid request.
context: A value to pass as the context_value to graphql execute function. By default is set to dict with request object at key request.
root_value: The root_value you want to provide to graphql execute.
pretty: Whether or not you want the response to be pretty printed JSON.
graphiql: If True, may present GraphiQL when loaded directly from a browser (a useful tool for debugging and exploration).
graphiql_version: The graphiql version to load. Defaults to "1.0.3".
graphiql_template: Inject a Jinja template string to customize GraphiQL.
graphiql_html_title: The graphiql title to display. Defaults to "GraphiQL".
jinja_env: Sets jinja environment to be used to process GraphiQL template. If Jinja’s async mode is enabled (by enable_async=True), uses
Template.render_async instead of Template.render. If environment is not set, fallbacks to simple regex-based renderer.
max_age: Sets the response header Access-Control-Max-Age for preflight requests.
encode: the encoder to use for responses (sensibly defaults to graphql_server.json_encode).
format_error: the error formatter to use for responses (sensibly defaults to graphql_server.default_format_error.
enable_async: whether async mode will be enabled.
subscriptions: The GraphiQL socket endpoint for using subscriptions in graphql-ws.
headers: An optional GraphQL string to use as the initial displayed request headers, if not provided, the stored headers will be used.
default_query: An optional GraphQL string to use when no query is provided and no stored query exists from a previous session. If not provided, GraphiQL will use its own default query.
header_editor_enabled: An optional boolean which enables the header editor when true. Defaults to false.
should_persist_headers: An optional boolean which enables to persist headers to storage when true. Defaults to false.
Contributing
Since v3, aiohttp-graphql code lives at graphql-server repository to keep any breaking change on the base package on sync with all other integrations. In order to contribute, please take a look at CONTRIBUTING.md.
