Change the syntax of a filter

[SBelkaid]

Is it possible to change the syntax of the filter to: filters: {[column_name]: {[operator]: [value_name]}}?

Not very easy but most likely possible, I think.

You need to override some parts of FilterSet:

• _generate_filter_fields to create a GraphQL schema in a different way https://github.com/art1415926535/graphene-sqlalchemy-filter/blob/f6c2123d4f19c99e2d48c342088f9ec7f09cb667/graphene_sqlalchemy_filter/filters.py#L571
• _translate_filter to implement a new method for getting the model field name and function key (FILTER_FUNCTIONS) https://github.com/art1415926535/graphene-sqlalchemy-filter/blob/f6c2123d4f19c99e2d48c342088f9ec7f09cb667/graphene_sqlalchemy_filter/filters.py#L724

This is an interesting task. It is possible that this module can have several types of GraphQL schema.

Pros:

• the user can choose the type of scheme

Cons:

• custom filters may not look consistent
• I think some queries may look strange ... filters: {username: {ne: "admin", in: ["user1", "user2"]}} ...

Example:

class UserFilter(FilterSet):
    is_admin = graphene.Boolean()

    class Meta:
        model = User
        fields = {'username': ['ne', 'in']}

    @staticmethod
    def is_admin_filter(info, query, value):
        ...

{
  allUsers(filters: {username: {ne: "admin", in: ["user1", "user2"]}, is_admin: true}) {
    edges { node { id } }
  }
}
