Optimize the QueryModel

[jieguangzhou]

For the Model

we can set a flag attribute: is_query (or use another name).

If is_query is set to True, then on the front end, all models with is_query can be automatically returned, eliminating the need to add a default QueryTemplate.

Additionally, the parameter box can be rendered dynamically based on the predict parameters.

model = MyModel(identifier="mymodel", is_query=True)

For the Query Select
This is built-in

class QueryModel(Model):
    query_func: Callable
    is_query: bool = True

    def __post_init__(self):
        self.identifier = self.identifier or self.query_func.__name__

    def predict(self, **args, **kwargs):
        return self.query_func(self.db, **args, **kwargs)

This is the user’s usage.

def get_limit_datas(db, table_name: str, filter: dict, limit: int=50, filter):
    select = db[table_name].find(filter).limit(limit)
    return list(select.execute())

q = QueryModel(query_func=get_limit_datas)

db.apply(q)

We can generate such a JSON, and the frontend can generate the corresponding page based on this JSON.​

{
    "model": "get_limit_datas",
    "parameters": {
        "table_name": "",
        "filter": {},
        "limit": 50
    }
}
