If this is the special value `aggregation.FIELDNAME` then this reducer will be aliased using the same name as the field upon which it operates. Note that using `FIELDNAME` is only possible on reducers which operate on a single field value. This method returns the `Reducer` object making it suitable for chaining. z(Cannot use FIELDNAME alias with no fieldN) FIELDNAMEr ValueErrorr)r rr r r r s z Reducer.aliascCs|jSr)rrr r r r7sz Reducer.args) rrr__doc__NAMErrr rpropertyrr r r r rsrc@s&eZdZdZdZdeddfddZdS) SortDirectionz@ This special class is used to indicate sort direction.

This request may then be passed to `client.aggregate()`. In order for the request to be usable, it must contain at least one group. - **query** Query string for filtering records. All member methods (except `build_args()`) return the object itself, making them useful for chaining.

This can either be a single string, or a list of strings. both cases, the field should be specified as `@field`. - **reducers**: One or more reducers. Reducers may be found in the `aggregation` module.

The key is the alias for the projection, and the value is the projection expression itself, for example `apply(square_root="sqrt(@foo)")` APPLYNrA)itemsr2r<)r kwexprrexprrDr r r applys   zAggregateRequest.applyrnumcCst||}|j||S)a Sets the limit for the most recent group or query. If no group has been defined yet (via `group_by()`) then this sets the limit for the initial pool of results from the query. Otherwise, this limits the number of items operated on from the previous group. Setting a limit on the initial search results may be useful when attempting to execute an aggregation on a sample of a large data set. ### Parameters - **offset**: Result offset from which to begin paging - **num**: Number of results to return Example of sorting the initial results: ``` AggregateRequest("@sale_amount:[10000, inf]") .limit(0, 10) .group_by("@state", r.count()) ``` Will only group by the states found in the first 10 results of the query `@sale_amount:[10000, inf]`. On the other hand, ``` AggregateRequest("@sale_amount:[10000, inf]") .limit(0, 1000) .group_by("@state", r.count() .limit(0, 10) ``` Will group all the results matching the query, but only return the first 10 groups. If you only wish to return a *top-N* style query, consider using `sort_by()` instead. )rr2r<r)r rrL_limitr r r limits *zAggregateRequest.limitcOst|ttfr |g}g}|D]}t|tr||j|jg7}q||g7}qdtt|g}|||dd}|dkrC|dt|g7}|j||S)a, Indicate how the results should be sorted. This can also be used for *top-N* style queries ### Parameters - **fields**: The fields by which to sort. This can be either a single field or a list of fields. If you wish to specify order, you can use the `Asc` or `Desc` wrapper classes. - **max**: Maximum number of results to return. This can be used instead of `LIMIT` and is also faster. Example of sorting by `foo` ascending and `bar` descending: ``` sort_by(Asc("@foo"), Desc("@bar")) ``` Return the top 10 customers: ``` AggregateRequest() .group_by("@customer", r.sum("@paid").alias(FIELDNAME)) .sort_by(Desc("@paid"), max=10) ``` SORTBYmaxrMAX) rBrr$r%r&rCr<getr2)r r;kwargs fields_argsfrDrPr r r sort_bys     zAggregateRequest.sort_by expressionscCs.t|tr|g}|D] }|jd|gq |S)z Specify filter for post-query results using predicates relating to values in the result set. ### Parameters - **fields**: Fields to group by.
