setting up multiple mutations

[anthonychung14]

Intended outcome:

We want to use the Mutation component, but conditionally execute on two Mutations (dependent on a prop received by the component it wraps).

I can't find documentation or use-cases that demonstrate this. Would this be a better use case for a HOC using graphql? or should I have a totally separate mutation function (that does A + B) rather than have one mutation that does A and maybe B?

Actual outcome:

<Mutation
        mutation={createMutation}
    >
        {(createNode) => {           
                const maybeCreateNewNodes = (propData) => 

                createNode({
                    variables: {
                        nodes: [newFolderNode],
                        options,
                    },
                });
               if (propData.specialProp) {
                   doSecondMutation({ variables: { specialProp }})
               }
            };

            return (
                <NewtemContainer
                    twoMutations={maybeCreateNewNodes}
                    {...props}
                />
            );
        }}
    </Mutation>

Stacking Mutation components doesn't seem to be a great use-case if I can just do

yield call (firstMutation)
if (specialProp)
yield call(secondMutation)

Thanks for the suggestion @anthonychung14. This is something that could be handled by using HOC's with graphql and Recompose's branch functionality. I agree though, it would be helpful to have something like this documented. PR's encouraged! 🙂

Just a quick update here - we're going to add a new nested mutation section to the docs shortly. This new section will cover:

• Example(s) showing how to handle nested mutations using the <Mutation /> component + render props
• Example(s) outlining how to leverage a composable render prop solution, like react-adopt (also covering the pros/cons of this approach)
• How leveraging too many mutations in a single component might mean it's time to refactor
• Outline how HOC's can still be used

Looking forward to those docs updates! I'm facing this situation, as well.

Same!! :) +1

+1: have need to mutate parent object, straight after create mutation of object itself.
Just managed this with 2 nested Mutation components, used their update props for cache and UI updates.
Question: Would it be equally good practice to nest Mutation component into ApolloConsumer component and use client.mutate({ mutation, variables, update }) ?

[denkrasnov]

Mutations can be more than just 2. So, looking forward for docs updates.
