Subgrounds requests with arguments

[cvauclair]

Description

Subgrounds fieldpaths and requests creation whould allow developers to specify variables in their queries.

The requests containing variables would act as request templates which can be used to create actual requests.

Example

sg = Subgrounds()
uniswapV2 = sg.load_subgraph("https://api.thegraph.com/subgraphs/name/uniswap/uniswap-v2")

swaps = Query.swaps(
  orderBy=Swap.timestamp,
  orderDirection='desc',
  first=500,
  where=[
    Swap.pair == Variable('address')
  ]
)

req_template = sg.mk_request([
  swaps.timestamp, 
  swaps.pair.token0.symbol,
  swaps.pair.token1.symbol,
  swaps.amount0In,
  swaps.amount1In,
  swaps.amount0Out,
  swaps.amount1Out
])

actual_req = req_template(address='0xb4e16d0168e52d35cacd2c6185b44281ec28c9dc')

data = sg.execute(actual_req)
